AT THE CENTER OF PLANT HEALTH

From the Editor Moving into a New Year This past year brought exciting changes for CAPCA with rebranding, a new website and an increase in our Government Relations outreach and engagement. With 2018 just beginning, you might notice some changes or new opportunities as we focus again on how to add value for our members each day, promote the value of the PCA license, and continue to offer support to local chapter leadership. CAPCA Ed has a streamlined calendar in 2018, reducing their meetings and increasing local support through collaborative Chapter meetings. Chapters accomplish their community outreach each year based on income from these local CE events and fundraisers, like golf tournaments and clay shoots. I encourage you to support these local events - your attendance at a Chapter CE event can impact scholarships and community outreach efforts. The CAPCA Annual Conference will be back in Anaheim October 14th-16th. This year’s theme, “At the Center of Plant Health,” is inspired by the new CAPCA brand. After selling out the Disneyland hotel and registration in 2016, we have worked with Disneyland to make some modifications to our room block. However, if you are planning to attend this year, register early to secure your hotel room on property before we sell out! (Registration will be available by May 15th.) Following the 2017 inaugural Spring Summit and field tour in the Temecula Wine Country, we will return to the Pechanga Resort April 24th and 25th. This year, we are collaborating with California Citrus Mutual for an educational Citrus Field Tour. Registration is open on our website but spots are limited for this smaller-format spring conference. Our Government Relations Committee is planning another Legislative Outreach Day to share in person with Sacramento politicians the value of the PCA license and a boots-on-the-ground perspective on issues impacting us. Visit the CAPCA website or read your spring Adviser for further details. Pathway to PCA expands outreach and continues to build on the success of the Student Networking Event. We will work with educators and students to support the transition from classroom to field, by fostering industry interactions with students and providing licensing resources. If you are looking for a college student to intern or field scout this season, we have a job posting board specifically designed for our student members. Check out this and other Pathway to PCA resources that have been integrated into the CAPCA website at www.capca.com/ pca/internships/. Thank you for your CAPCA membership in 2018! Without your ongoing engagement and support, CAPCA would not be able to grow outreach and programming as we have the privilege to do again this year! █ Ruthann Anderson, Editor ruthann@capca.com

LEADERSHIP

CAPCA Update: Expanding Our Outreach By Rick Wescott, CAPCA Chairman

It has been a year since I was elected to be your chairman and what a difference a year makes. There have been many changes and many challenges that CAPCA has had to engage in this past year.

come into compliance and register their hives with the Agricultural Commissioners so that PCAs will know where bees are located to mitigate any issues with pesticide applications.

We hired a new lobbyist, George Soares of Kahn, Soares & Conway, LLP. We changed the CAPCA logo to the leaf in hand, which better represents what CAPCA does in the agricultural and green industry. We resurrected the legislative day visits with legislators in Sacramento, and made it a new priority for our Government Relations Committee to be more engaged with matters happening with California government. We are building coalitions with other Ag organizations to create a bigger voice for agriculture and the green industry.

So what does 2018 have in store for us? One thing I can assure you is that there will be no shortage of issues affecting our ability to do our jobs as PCAs. Unfortunately, the climate in Sacramento is not favorable for agriculture or the green industry. Your CAPCA state board is up to the task of putting your best interests first and doing what it takes to preserve the industry and ensure that California remains the most productive agricultural region in the world.

We were challenged by federal and California EPA on several chemicals that they wanted to ban or severely restrict. CAPCA responded by writing letters of support for phyrethroids, neonics and chlorpyrifos. We opposed the school buffer zone proposal by CDPR as unwarranted and joined other Ag groups in opposition efforts. We have also been very active in mitigating nitrogen management liabilities for the CCAs signing off on nitrogen management plans. We are involved with getting beekeepers to

I would like to close by congratulating Harry Peck on his retirement from DOW AgroScience after 44 years of service. Harry was one of the founding members of the Tulare-Kings CAPCA chapter when CAPCA was first formed in 1975. He has served on the Tulare-Kings board for most of those years and held every office except treasurer. He also served as a state board representative for 14 years. He was awarded CAPCA Member of the Year in 2011. Thank you Harry for your many years of service to CAPCA and enjoy your retirement. â&#x2013;&#x2C6;

Full bloom is no time to take a chance on your crop. Itâ&#x20AC;&#x2122;s when yield is determined, as well as the quality and cleanliness of your crop. Merivon fungicide offers longer lasting disease protection and consistently delivers higher crop quality. It also provides Plant Health benefits that can help lead to higher crop quality and increased yields. Contact your BASF representative or visit GrowSmartAlmonds.com.

PATHWAY TO PCA

CAPCA Continues Student Outreach in 2018 Ariana Zamora, So. California Representative Pathway to PCA had a great resurgence in 2017. We visited eight target schools that include Cal Poly, Cal Poly Pomona, Mt. Sac, University of Arizona – Yuma, Modesto Junior College, CSU Stanislaus, CSU Fresno and UC Davis. We will plan visits to the same eight schools in 2018 with hopes to grow the program in years to come.

The Pathway program offers assistance with the application process and puts on the Student Networking Event (SNE) at the Annual Conference. The 2018 SNE will take place on October 14, 2018 at the Disneyland Hotel in Anaheim, CA! We hope to work with all 16 chapters to sponsor student registration and travel costs. Want more information on how to get involved, contact us today!

What does a Pathway to PCA campus visit look like? CAPCA Regional Representatives, Ariana Zamora and Jackie Tabarez, give a brief overview of the PCA profession and requirements for the application process. If we’re lucky enough to have CAPCA members join us for the visit, the PCA talks about their schooling and experience as a PCA. This usually generates many questions from students that vary from advice on curriculum to what kind of truck they drive.

How can you get involved with Pathway to PCA? • Volunteer to visit one of the target schools • If there’s a school that isn’t one of our target campuses, we can still help! Book an event with the campus and we’ll send you collateral and giveaways for students. • Sponsor the Student Networking Event or individual student registration and/or travel Scheduled 2018 Pathway to PCA Visits • April 11, 2018 – Cal Poly (sponsored by Central Coast CAPCA) █

PCA PROFILE

Dennis Fuller: Embracing the Diverse Demands of the PCA By CAPCA Staff Dennis Fuller obtained his PCA license in 2013, but has been involved in many aspects of California agriculture since growing up on a family farm near Riverdale. He attended Cal Poly San Luis Obispo and graduated with a Bachelor’s degree in Ag Science and minor in Ag Business. Following college, he combined a passion to help people with his background in agriculture to become a high school ag teacher at Hanford High School, before making a career change. He cites his time on the family farm as a part of shaping his career path. “It gave me the work ethic needed to be a part of agriculture.” Primarily, the farm produces walnuts and almonds, but when he was younger his family grew mostly cotton and alfalfa. He recalls running the module builder and even hoeing cotton as a kid, and a conversation with a PCA named Randy Davis. “I thought everyone took July 4th off,” Fuller recalls. “But Randy asked me ‘Do you think crops get the day off?’ so I worked all day in over 100-degree heat. It was miserable. That’s when I realized there was something different about people in this business.” The mentality that “crops never take a break” is a large part of his work ethic. Throughout high school and college, he’d considered becoming a PCA. It wasn’t until working as an intern for Helena that his eyes started to open: “I was always under the impression that a PCA was just a bug checker. But after those summers I found out there was much more to be being a PCA.” When looking to transition from teaching, Fuller became even more aware of the types of jobs available. “I didn’t realize being a PCA was so broad.” “After 5 years [of teaching], I was ready for a career change. This is where I found the manufacturing side of being a PCA,” Fuller says. “This job allows me to teach my peers – or more times than not my peers teach me – about chemistry while helping farmers make decisions that will directly affect production.” Now, in his current position with ADAMA, he has the privilege of being involved in a large array of crops from asparagus to walnuts. He prefers working in almonds and walnuts, but still really enjoys looking at cotton. Until recently, his area covered Hanford down to San Diego out to the coast. With the wide variety of crops grown throughout such a diverse geographical area, Fuller has gotten good at research and developed a strong network of resources to support the PCAs he works with. “When I first started, I got a phone call about dill – I had no idea what dill looked like in the field,” he recalls laughing. “That was part of why I joined CAPCA – for the networking.”

DENNIS FULLER CAPCA Chapter: Tulare-Kings Education: Cal Poly San Luis Obispo Year of PCA License: 2013 Employer: ADAMA

Fuller currently serves as the Tulare-Kings Chapter Vice President and State Board Director. “I volunteered to be a part of this organization because I believe in the goals and understand that no one person can do what CAPCA does by themselves… I realized CAPCA has a lot of things to offer and without an organization backing our license we would be fighting the fight as individuals.” When talking about the satisfying highlights of being a PCA, Fuller remarks that in his position he doesn’t hear the ultra-success stories or get many thank you’s. “But you can’t be in it for the thank you… I enjoy seeing other people have success. Whether that is a farmer protecting his crop or a PCA trying to solve a problem, it’s fun to watch people succeed.” He and his wife Emily have a toddler named Jax, and are expecting another child in June. Outside of work, he enjoys hunting and riding standup jet skis. █

California Adopts Rules on Agricultural Pesticide Use Near Schools and Day-Care Facilities Louie B Mendoza Jr, Agricultural Commissioner, Butte County The California Department of Pesticide Regulation (DPR) has adopted new rules that would give further protections to children when agricultural pesticides are applied close to schools and child day-care facilities. School site means any property used as a child day care facility, as defined in Health and Safety Code section 1596.750, or a public kindergarten, elementary, or secondary school. This includes all areas of the property used on weekdays by children who attend such facilities or schools, or other similar areas identified by the commissioner, such as a park adjacent to a school that is used by the school for recess, sports, or other school activities. It does not include family day care homes as defined in Health and Safety Code section 1596.78; any private kindergarten, elementary, or secondary school facilities; or vehicles or bus stops not on school site property. Many K-12 schools and child day-care facilities are located near farming operations and increasingly teachers, parents and the public want to know whether the chemicals being applied could adversely affect them. Following extensive public and stakeholder input, the new regulation provides an extra measure of protection to these sites from the risk of short-term pesticide exposure. It also provides advance notification when certain pesticides are applied, so as to increase communication between growers and schools or child day-care facilities, and help them in responding to inquiries and potential incidents. The regulation is effective on January 1, 2018 which will: • Prohibit many pesticide applications within a ¼ mile of public K-12 schools and licensed child day-care facilities during school hours, Monday through Friday between 6 a.m. and 6 p.m. This means that during this time frame and for the allotted distance: o No pesticides can be applied by aircraft. This includes planes, helicopters, and all aerial means of application. o No pesticides by air blast sprayer or by sprinkler (chemigation). o Most dust and/or powder pesticide applications will be prohibited. o No fumigant applications will be allowed. • Growers with fields within ¼ mile of a school site/licensed child day care facility must provide annual notification; which lists all the pesticides expected to be used during the upcoming July through June school year. This must be provided to the principal or licensed

CAPCA ADVISER | FEBRUARY 2018

child day care facility administrator by April 30 each year. This notice must include among other things: o Name of each active ingredient and examples of pesticide products expected to be used. o A map showing the location of the field to be treated. o Contact information for the grower/operator and the County Agricultural Commissioner (CAC). o Web site address for the National Pesticide Information Center, which provides sources of information or additional facts on pesticides. In a cooperative effort, the California Department of Pesticide Regulation and the California Association of Agricultural Commissioners and Sealers (CACASA) have developed an on-line tool for growers to provide the notification to schools & daycare facilities. Calschoolnotify.org is a secure website which will include pesticide permit data and maps to both parties. The schools will verify its campus grounds, contact information, and any additional area that children may use during the school day. Growers will have the ability to see their property maps that are within the ¼ mile of the school, contact information, and list the potential chemical active ingredient to be used during the season. This is where PCA’s will play in key role in assisting growers with their selection of potential active ingredients. Once all the information is verified and entered the information will be sent to all parties including your local Agricultural Commissioner (CAC). Agricultural Commissioners throughout the state are providing updates on the new regulation through continuing education classes and grower/industry venues. As part of this outreach, we encourage growers to work with their PCA to review sites that are partially within a ¼ mile of schools/day care centers to see if they want to “split” a portion of the site affected by the new regulation. Additionally, growers will rely on PCA recommendations to help them comply with application exclusion time frames and notification. California has varying microclimates and schools have various extracurricular school activities. Therefore, the regulation will allow the individual school site/licensed child day care facility, the grower and the CAC to develop an alternative written agreement, to which all three parties must consent, that provides equal or more protection as the regulation. This agreement will be enforced by the CAC. For more information or detail into the regulation contact your local Agricultural Commissioner or the Department of Pesticide Regulation. █

CCA UPDATE

WR CCA Nitrogen Management Training Returns in 2018 The University of California Agriculture and Natural Resources (UC ANR) will be joining with the California Department of Food & Agriculture (CDFA) FREP to offer nitrogen management training once again to Western Regional CCAs. Additionally, CCA candidates who have passed both the International and State CCA exams and are in the CCA credential process will also be eligible for this training in 2018 (Note: Those CCAs who completed the certification previously are not required to take the certification training again.) The WR CCA program has been identified as an ideal resource to assist growers with developing nitrogen management plans and implementing best management practices. The main goal of the training program is to facilitate Western Regional CCAs’ understanding of sound nitrogen management practices and make informed recommendations to growers. The course will cover 1-½ days, with the first day being a general session focused on identifying the key objectives, nitrogen cycle in crop production systems, nitrogen sources, irrigation & nitrogen management, nitrogen budgeting and future resources. The second morning will have concurrent sessions with emphasis on annual and permanent crops and will include nitrogen planning practices. CDFA is offering just one opportunity in 2018 to attend this training: March 6-7, 2018 at the Wedgewood Wedding & Banquet Center in Fresno, CA. Registration will be online only – no on-site sign ups. Seminar fee will be $160.00 covering lunch on Day 1 and 11 CCA CEU hours. No refunds. Attendance is mandatory for both days of the seminar in order to be authorized to consult on nitrogen mitigation planning for water board regulatory purposes. Those CCAs who have previously received their CDFA Nitrogen Management training may attend for CCA CE hours (depending on space availability) but will not receive any additional certification of attendance. CAPCA is providing the registration and administrative services for the nitrogen management seminars. If you have questions, please contact Adam Barsanti at adam@capca. com or Jackie Tabarez at jackie@capca.com, or call CAPCA at (916) 928-1625. █

CCA UPDATE

The Water Board has published a new nutrient management Draft Order. What does it mean for CCAs? By Patrick Dosier, on behalf of the Western CCA Board

In October 2017, the State Water Board (SWB) released its second Draft Order for the Eastern San Joaquin watershed (an area also referred to as Region 5). This Orderâ&#x20AC;&#x2122;s language and timelines are directed at the Central Valley Regional Water Board (CVRWB). However, the SWB states very clearly that is also intended to set precedence for all of the other watersheds in California, including the Central Coast. The Draft Order is very lengthy and complex. This article sets out to summarize how it will affect Certified Crop Advisers (CCAs). The first Draft Order left many unanswered questions regarding liability risks to CCAs who certify the Irrigation and Nitrogen Management Programs (INMPs). The second Draft Order goes a long way towards addressing these concerns. CCA risk and liability will be limited by the following: 1. The Order states that CCAs are not responsible for verifying the accuracy of the information that they are given by their growers when developing an INMP. They must certify that it is accurate to the best of their knowledge. 2. The Order states that CCAs are not responsible for ensuring that the grower adheres to the INMP, nor are they considered responsible if the grower deviates from the INMP.

CAPCA ADVISER | FEBRUARY 2018

3. The certification will not create any liability for environmental violation claims. This limits the scope of what an INMP is and limits how it can be challenged in court. 4. The Order sets up a system by which growers who join thirdparty coalitions will be assigned an anonymous ID number known only to the grower and to that coalition. INMP reporting will be made to the SWB via these anonymous numbers. While this is designed to protect the privacy of growers, it also results in increased privacy for CCAs who write the INMPs for those growers. The above-mentioned components were included in the Order in response to educational efforts made by the Western CCA Board and to outreach made by CAPCA. The end result is that it appears that qualified CCAs will be able to obtain adequate insurance coverage, the regulations will contain language protecting CCAs and now CCAs will be able to confidently certify INMPs on behalf of their grower clients. Finally, in response to the second Draft Order, CAPCA responded to the SWB by acknowledging the liability protection language, emphasizing the critical need for accurate, science based, crop nitrogen removal coefficients and stating our position that the 925+ qualified Western Region CCAs can handle the coming INMP certification challenge. â&#x2013;&#x2C6;

Special to the Adviser

Take Control of Your Fertility Program Dylan Rogers, Sales Account Manager for AgroLiquid The 2018 almond crop is upon us. Trees are beginning to break dormancy, soon full bloom will occur, and the honeybees will be busy pollinating what will be our highest yielding crop to date - we hope. There are many factors that will affect the yield potential of this year’s crop; some we can control and others we cannot. Mother Nature and the weather are out of our hands - all we can do is hope that it works in our favor. We can fight disease and insect pressure, but we cannot prevent it completely. One factor we do have complete control over, however, is our fertility program and ensuring we supply the trees with the nutrients they need to produce that high-yielding crop. Soil Samples A great starting point for building your seasonal fertility program is by assessing what you have in the soil. Looking at a current soil sample will give you an idea of what needs to be done in season to ensure adequate fertility for maximum yields. There are multiple things to consider when reading a soil test. You may see that most or all of your nutrient levels read adequate or high, however, the ratios of some nutrients are more important than the levels. For instance, iron and manganese are antagonistic to each other. You may have adequate levels of both nutrients in your soil, but if the ratio is off, you may see symptoms of deficiency. You need more iron than manganese in the soil. The ideal ratio is 2:1 iron to manganese. The closer this ratio gets to 1:1, the more likely you will see an iron deficiency in season. The ratio of phosphorus to zinc is also an important factor. A ratio of 10:1 phosphorus to zinc is the ideal balance between these two nutrients. If phosphorus levels get too high, it may induce a zinc deficiency. These are just two examples of many ratios that should be addressed in your soil. A soil sample will ensure you have the information you need to get off on the right foot to maximizing this season’s yield. 24

CAPCA ADVISER | FEBRUARY 2018

Bud Break, Pink Bud, Bloom During the period in which fruit buds are swelling, the trees are also working below the soil surface. A new flush of feeder roots are pushing out, and having an adequate supply of phosphorus and soil moisture is critical in the development of these new roots. Choosing a phosphorus fertilizer that is protected from tie-up in the soil ensures the most return on this investment. Following bud swell and new root development will be bud break, a period in which flower and pollen development are crucial. These fruiting buds that will become flowers are the fate of this season’s crop, so we do everything possible to protect and ensure their viability. Foliar applications of phosphorus, calcium, zinc, boron, and molybdenum can be beneficial, as they play important roles in all aspects regarding pollen. Fruit Development The tree’s highest demand for nitrogen and potassium is from fruit set to harvest. Supplying these two nutrients in adequate amounts is crucial to achieve a high yielding crop. Nitrogen is a critical component of many plant parts and functions. It is needed to produce chlorophyll, DNA and RNA, and to synthesize amino acids. As an example, one acre of almonds, yielding 2,600 pounds, will remove about 83 pounds of nitrogen. Choosing a nitrogen fertilizer that is low in salts and less likely to leach or volatilize will ensure optimum uptake by the tree and give you the most return on your fertilizer investment. Potassium is also very important for many plant functions and is required in large amounts. Potassium plays a major role in the opening and closing of stomata, photosynthesis, translocation of sugars, and many other plant processes. Again using almonds as an example, that same acre, producing 2,600 pounds of almonds, will remove about 19 pounds of potassium. There are some important things to take into

consideration when choosing a potassium source. Almonds are very sensitive to salts such as chlorides and hydroxides. Some fertilizers can even be toxic if applied at higher rates. Choose a potassium source that is free of chlorides and hydroxides to ensure maximum uptake and to minimize potential for crop injury. Taking control of your fertility program this season will help achieve maximum yield potential. Again, there are multiple factors that are out of our control so taking advantage of the factors we can control is important. Choose your fertilizers this season with plant and soil health in mind to maximize your return on investment. █

Proper Selection and Use of Personal Protective Equipment (PPE) in California Lisa Blecker, Pesticide Safety Education Program Coordinator, UC Statewide IPM Program Personal protective equipment (PPE) is essential for preventing pesticide illnesses and exposure. A review of the Pesticide Illness Surveillance Program (PISP) database (DPR 2013) showed that 32% of reported handler pesticide illnesses that involved skin or systemic symptoms were due to failure to wear the appropriate PPE. Eye injury occurred in 55% of all handler illness cases (either alone or in combination with other symptoms/injuries). Skin injury occurred in 28% of all these cases (either alone or in combination with other symptoms/injuries).

Figure 1. Glove Category Selection Key developed by the California Department of Pesticide Regulation (DPR) to help label readers identify the correct glove material.

The data make it clear: selecting the appropriate PPE, and wearing it correctly, can reduce the risk of pesticide-related illness. The minimum required PPE for pesticide handlers in California is detailed in the California Code of Regulation and is often more strict than PPE listed on pesticide labels. For example, Section 6738.1 (CCR 2015a) specifies that chemical-resistant gloves and protective eyewear are required for most handling tasks, and that coveralls are required when handlers are applying pesticides with a WARNING or DANGER signal word. Gloves California regulations require employees to wear chemical-resistant gloves for most pesticide handling tasks, even if the label does not require them. Chemical-resistant glove materials are limited to: barrier laminate, butyl rubber, nitrile rubber, neoprene rubber, natural rubber, polyethelyene, polyvinylchloride (PVC), and viton rubber (CCR 2015c). Gloves made of most chemical-resistant materials need to be 14 mils (1 mil=0.001 inch) or thicker when handling pesticides. The only exemptions are polyethylene and barrier laminate, which can be any thickness. The U.S. Environmental Protection Agency (U.S. EPA) Chemical Resistance Category Selection Chart for Gloves (EPA 2016) is used

to determine the type of gloves to be listed on pesticide labels, based on glove material resistance to solvents used in pesticide formulations. That is to say, not all chemical-resistant gloves will protect you from exposure to all pesticides. The specific material and thickness are important for your protection. Pesticide product labels are required to reference the protective glove materials on labels, and they do so either by specifying by name (e.g., nitrile, butyl, etc.) or by code (A through H). The California Department of Pesticide Regulation (DPR) developed a wallet-sized Glove Category Selection Key to help label readers identify the correct glove material for their situation (Fig. 1). Viton gloves that are at least 14-mils thick can be worn when the label specifies viton gloves, or when it specifies gloves in categories A, C, E, F, G, and H.

Protect Tree Nut Orchards for the Long Haul Productive orchards require a lifelong approach to tree health and a long-term strategy for disease management. Choosing the right approach this year impacts the productivity of the tree next year and orchard health for the long haul. The first step in ensuring a healthy orchard is protecting trees at bloom when they undergo rapid growth amid the most intense disease pressure of the season. Brown rot blossom blight is among the most destructive. It can infect and kill flowers, fruiting spurs and shoots from pink bud to petal fall. In the case of severe infection, brown rot blossom blight can move into and kill the woodier tissue of the tree. This can lead to the formation of a canker that can kill the branch while serving as a host to the fungus to enable future infections. PREVENT RE-INFECTION

Brown rot blossom blight favors rainy conditions when temperatures are in the mid-70s, meaning spring in California is the ideal setting for the disease to thrive. Even in times of low rain, infection can occur due to dew and early morning moisture. If orchards are not sprayed for infection, brown rot can spread quickly, even in seasons with little rain. Controlling it early prevents inoculum from overwintering and re-infecting orchards the following season.

ENSURE TREE HEALTH ALL SEASON, HARVEST AFTER HARVEST.

Handlers must wear chemical-resistant gloves made of the material specified on the pesticide product labeling. If the label does not specify that gloves are required, or if it only states that chemicalresistant or waterproof gloves are required, handlers can choose to wear gloves of any chemical-resistant material, provided they are the appropriate thickness.

Figure 2. Disposable chemical-resistant gloves allow for more dexterity and motor control when adjusting nozzles. Photo by C. A. Reynolds.

Disposable gloves made of chemical-resistant materials (e.g., nitrile and neoprene) are permitted. If they are less the 14-mils thick, they can be worn for a maxiumum of 15 minutes and only when the handler needs a higher level of dexterity and motor control, such as making fine adjustments to nozzles. Disposable nitrile gloves that are 15-mils thick are available, and their use is not restricted to 15 minutes. They can be worn for all handling tasks because they meet the minimum thickness requirement (Fig. 2). Chemical-resistant gloves must be unlined. Built-in glove liners are made of flock or cotton, which absorb pesticides and keep them trapped next to your skin. Handlers can wear separable, absorbent glove liners, such as cotton, under their chemical-resistant gloves. Glove liners can be worn only if all three of these conditions are met: 1) the pesticide label does not prohibit the use of a glove liner; 2) the glove liner does not extend beyond the chemical-resistant glove, and 3) the glove liner is disposed of at the end of the day or immediately after it becomes contaminated with a pesticide. Eyewear California regulations require employees to wear protective eyewear for most handling tasks, even if the label does not require it. Handlers must wear the type of eyewear that is specified by the pesticide product labeling. If the label does not specify that eyewear is required, or if it requires “protective eyewear”, handlers can choose to wear either a faceshield, goggles, or safety glasses that provide front, side, and brow protection (CCR 2015b). All types of protective eyewear must be labeled “Z87.1” or “Z87+” to indicate that it meets the 2010 American National Standards Institute standard for impact resistance (ANSI Z87.1). This is done using permanent, raised lettering (Fig. 3). This label means that the manufacturer certifies that its eyewear meets the defined baseline of protection. If you wear prescription glasses, your glasses must not interfere with the function of the protective eyewear. If a NIOSH-approved full face respirator is required, handlers do not need any additional protective eyewear. Coveralls California regulations require employees to wear coveralls when handling pesticides with the signal words DANGER or WARNING, even if the label does not require them. An exception would be a fumigant application, unless the label specifically requires it. A coverall is a one- or two-piece garment made of closely woven fabric that covers the arms, torso, and legs. Coveralls are most commonly made of Tyvek or tightly woven cotton, and must be provided by the employer. Coveralls are worn in addition to work clothing—that is long-sleeve shirt, long pants, socks, and closed-toe shoes.

UC IPM, CONT., Proper Selection and Use of Personal Protective Equipment (PPE) in California

Pest Control Advisers Pest control advisers (PCAs) that need to enter a treated field before the restricted entry interval (REI) has expired must wear PPE. During the REI, pesticide residues are more concentrated and are more likely to cause illness. PCAs can choose to wear PPE for early-entry tasks, which is listed in the “Agricultural Use Requirements” section of the label; PPE for handlers, which is listed in the “Precautionary Statements” section of the label; or a standard set of PPE, which includes: coveralls, shoes plus socks, chemical-resistant gloves and eye protection.

Figure 3: Protective eyewear must be labeled with “Z87.1” or “Z87+” in permanent, raised lettering. Photo by C. A. Reynolds.

PPE regulations in California are often stricter than the PPE that is required by pesticide labels. Chemical-resistant gloves of the appropriate thickness, and protective eyewear that meets the ANSI Standard are required for most handling tasks. Coveralls on top of work clothing are required when handlers are applying pesticides with a WARNING or DANGER signal word. Failure to wear the appropriate PPE is documented to cause handler illnesses—eye injury and skin exposure are the most common. We all have a responsibility to protect ourselves and our employees from pesticide exposure. █ References

Naturally Occurring Fungus as a Potential Microbial Control Agent for Spotted-wing Drosophila Surendra K. Dara, Strawberry and Vegetable Crops Advisor, UCCE, San Luis Obispo and Santa Barbara Counties, CA; Tom Mann, Mississippi Museum of Natural Science, Jackson, MS; De-Wi Li, Connecticut Agricultural Experiment Station, Windsor, CT, Blake Layton, Mississippi State University, Mississippi State, MS; Richard Cowles, CT Agricultural Experiment Station, Windsor, CT; Blair Sampson, USDA-ARS, Poplarville, MS

Spotted-wing drosophila (SWD), Drosophila suzukii is an invasive pest that attacks many cultivated and wild fruits. With the help of a strong, saw-like ovipositor or egg laying appendage, SWD is able to deposit eggs in ripe and occasionally in unripe or developing fruit unlike other Drosophila spp., commonly known as vinegar flies or fruit flies, that attack ripe or fallen fruit. Larvae develop in the fruit and pupation occurs either in or outside the fruit. Blueberry, caneberries, cherry, peach, and strawberry are some of the commercially important fruit crops in California that are vulnerable to SWD damage. Some of the control practices currently adopted in organic and conventional crops include monitoring with lures, application of pesticides, use of exclusion netting, and field sanitation. Among the microbial control options, entomopathogenic fungi such as Beauveria bassiana, Isaria fumosorosea, and Metarhizium brunneum (=M. anisopliae) against adults and entomopathogenic nematodes such as Heterorhabditis spp. and Steinernema spp. against pupae in the soil can be potential choices. A few laboratory studies that evaluated these options showed limited efficacy of the most except for B. bassiana treatments in Italy and M. brunneum in Oregon that appeared promising (Gargani et al., 2013; Cuthbertson et al., 2014; Woltz et al., 2015). Biocontrol potential with predators and parasitoids is also limited based on current research data (Haye et al., 2015; Renkema et al, 2015; Woltz et al., 2015).

In light of limited microbial and biocontrol control agents, a recent outbreak of fungal epizootics in SWD on fig offers a potential natural control option. SWD populations in a small fig orchard in Clinton, Mississippi were infected by a fungus in June, 2017. Unusually cool and wet conditions caused epizootics of a fungus, which was later identified by Connecticut Agricultural Experiment Station scientists as Entomophthora muscae or a closely related species. SWD first appeared in blueberry, blackberry, and mulberry plots of this orchard in 2012 and infestations on figs were noticed only in 2017. Other SWD hosts that are grown at this orchard include grapes, pears, and strawberries. Having a variety of hosts with extended availability of fruits could have supported SWD populations at this location. Unlike B. bassiana, I. fumosorosea, and M. brunneum (Class Deuteromycetes: Order Hypocreales), Entomophthora spp. belong to a different fungal group (Class Zygomycetes: Order Entomophthorales). Entomophthora spp. cause disease outbreaks in their host populations when environmental conditions are favorable with high humidity and low temperature aided by high host densities. Entomophthora muscae is considered to be a species complex infecting a variety of dipteran families including Drosophilidae (Goldstein, 1927; MacLeod et al., 1976; Gryganskyi et al., 2013). However, it appeared to be less pathogenic to the common fruit fly, Drosophila melanogaster compared to other dipteran species (Steinkraus and Kramer, 1987). Entomopathogenic fungi usually take 3-5 days to kill their hosts. Infection process typically starts when host insect comes in contact with the conidia (asexual spores) of the fungus (Brobyn and Wilding, 1983). Primary conidia either produce a germ-tube that penetrates through the host cuticle or produce secondary conidia (which later produce germ-tubes) or hyphae. Both enzymatic degradation of cuticle and mechanical pressure by the penetration peg of the germ-tube aid in fungus gaining entry into the host body. Hyphal bodies are formed inside the host, invade the fat bodies and other tissues, and eventually cause death of the host insect.

CAPCA ADVISER | FEBRUARY 2018

entomophthoralean fungi may produce environmentally resilient resting spores to survive cold winters (Eilenberg and Michelsen, 1999) or survive as hyphal bodies in the dead (Keller, 1987) or winter hosts (Klingen et al., 2008). Other overwintering options for these fungi include infections in their host insects on winter crops (Dara and Semtner, 2001) or infections in alternative host insects (Eilenberg et al., 2013).

The fungus later emerges from the intersegmental membranes and conidiophores or spore bearing structures produce conidia that are dispersed to continue the infection cycle. Infected flies become sluggish and typically fly to the higher parts of the plant canopy where they become attached to plant surfaces with rhizoids (peg like structures that emerge from the ventral or lower side of the insect body) and sticky secretions (Steinkraus and Kramer, 1987). This process increases the chances of disease spread as insect cadavers are securely attached to plant surfaces and infective conidia are dispersed from a higher elevation in the canopy. When host populations diminish and during the winter months,

Entomophthoralean fungi are difficult to culture in vitro and do not have the biopesticide potential as the hypocrealean fungi. However, they can be significant mortality factors in some areas and bring down dense host populations. Neozygites fresenii epizootics in cotton aphid, Aphis gossypii (Steinkraus et al., 1995), Entomophaga maimaiga in gypsy moth, Lymantria dispar (Hajek and Elkinton, 1991), and Pandora neoaphidis in green peach aphid, Myzus persicae populations (Dara and Semtner, 2007) are some of the examples for the natural control of insects by entomophthoralean fungi. Anecdotal reports indicated outbreaks of a possible entomophthoralean fungus in aphids on some vegetables in California, but there are no published reports of fungal outbreaks except for a study in the 1980s. Mullens et al. (1987) reported E. muscae epizootics in house fly (Musca domestica), little house fly (Fannia canicularis), and predatory fly (Ophyra aenescens) populations in Southern California poultry facilities. Similarly, E. muscae infections in adult onion fly (Delia antiqua) and seed corn maggot (D. platura) caused significant population reductions in Michigan (Carruthers et al., 1985). In a recent study in North Carolina, E. muscae infected both cabbage maggot (D. radicum) and a predatory fly (Coenosia tigrina).

The extent of E. muscae epizootics in Mississippi populations of SWD show promise for the natural control of this pest. While large scale in vitro production of the fungus may not be practical at this moment, small scale production in vivo or a specialized culture medium is possible for laboratory and greenhouse studies. In vivo culturing of entomophthoralean fungi and releasing infected live arthropods was successful for a large scale release of Neozygites tanajoa for controlling the cassava green mite, Mononychellus tanajoae in West Africa (Hountondji et al., 2002) and a small scale release of P. neoaphidis for controlling M. persicae in Virginia (Dara and Semtner, 2006). Future studies will shed light on the potential of E. muscae in SWD integrated pest management. â&#x2013;&#x2C6; FEBRUARY 2018 | CAPCA ADVISER

Redbay Ambrosia Beetle Poses Potential Threat to California's Avocado Industry Sonia Rios, University of California Cooperative Extension (UCCE), Riverside/San Diego; Ben Faber, UCCE Ventura/Santa Barbara; Akif Eskalen, UC Riverside; Peggy Mauk, UC Riverside; Mary Lu Arpaia, UC Riverside California produces approximately 90 percent of the nation's avocado crop. California avocado growers compete in both the domestic and international markets with countries with much lower costs of production and better labor availability. To stay competitive will require more efficient farming strategies and a significant increase in productivity on the part of California growers, especially with the increase of water costs and labor constraints. To adapt, growers need to dramatically increase yield per acre using the same amount of water or less. In addition to cultivation challenges, invasive pests can cause even more challenges to growers. In recent years, California avocado growers have had to deal with the Polyphagous and Kuroshio Shot Hole Borers, collectively known as the Shot Hole Borer complex (SHB). These invasive wood-boring beetles attack over 50 tree species in Southern California, including the avocado tree. They spread a pathogenic fungus (Fusarium euwallacea) which can severely debilitate or even kill its host. Current research has determined that the SHB does not kill avocado trees, however, even this theory has its controversy since in Israel where the Polyphagous Shot Hole Borer also exists, it has been known to severely debilitate avocado trees. Another invasive ambrosia beetle, the redbay ambrosia beetle (RAB; Xyleborus glabratus), is currently spreading through the Florida avocado industry (Photo 1). This beetle has been slowly spreading across the southeastern United States and is currently found as far west as eastern Texas. Therefore, the California growers need to be aware that this pest-disease complex may spread to California and cause severe problems to the state's avocado industry. RAB has a fungal symbiont, Raffaelea lauricola, that causes the deadly Laurel Wilt Disease, LWD (photo 2). Laurel wilt affects redbay (Persea borbonia) and other tree species of the Laurel family (Lauraceae), including avocado. R. lauricola is introduced into host trees when RAB colonizes a tree. 36

Native to Southeast Asia, RAB has similarities to our current ambrosia pests, Polyphagous and Kuroshio shot hole borers. However, the fungus associated with laurel wilt is unlike the disease here in California. Trees become infected when female beetles attack host trees and introduce the pathogen into the xylem while boring their galleries (Photo 3). The infection restricts the flow of water in the tree, induces a black discoloration in the outer sapwood and causes the leaves to wilt. The tree dies so fast that it doesn't even have a chance for the leaves to fall off the dying branches (Photo 4). Adult RAB are very small (~1/16-inch-long), dark brown to black

in color, slender and cylindrical in shape and spend most of their life within the tree. Larvae are white, legless grubs with an amber colored head capsule and are found within galleries throughout infected trees. Female beetles can produce flightless male offspring without mating, but females may mate with their male offspring or sibling males to produce males and females. Females greatly outnumber males in populations. In the Southeast, the RABâ&#x20AC;&#x2122;s lifecycle from egg to adult appears to take 50-60 days, and there appear to be multiple overlapping generations per year (Hanula et al. 2008). Female beetles emerging from galleries may reinfest the same tree or disperse in search of new hosts. Host trees can remain standing for years and may continue to serve as host material for the beetles for several months after initial colonization. Their flight activity peaks in the late afternoon and early evening. It is known that ambrosia beetles are notoriously difficult to control because they are inside the tree most of their lifecycle versus being outside the tree.

more attractive to beetles. The beetles prefer dense canopies with overlapping leaves and branches. Chipping infected trees is effective in reducing the spread of the disease; however, chips must be small (1 square inch pieces or smaller) as possible and dried quickly so that the wood is not conducive to fungal growth. A potential pitfall to this approach is that the smell of the chipped wood can attract other wood boring insects. Research is currently being conducted to determine if different commercial formulations of insecticides can be effective in controlling the beetle.

RAB can fly short distances, but laurel wilt fungus spreads more quickly through the movement of insect infested plant material, such as firewood. Additionally, the pathogen also spreads to other ambrosia beetle vectors. This happens when beetles feed on diseased trees and become contaminated with spores of R. lauricola. Spread can also occur through root-grafting between trees. Sanitation is the most effective way to manage this problem. Scouting for wilted branches and quickly removing the wilted branches has been the key to early intervention and eradication. It is suggested to remove symptomatic trees immediately upon their identification. Since when frass and streaks in the wood are apparent, the tree is already infected and has been for some time. As soon as a grower sees the wilt in the branches, itâ&#x20AC;&#x2122;s time to move quickly. Verticillium wilt and Phytophthora root rot can be mistaken for laurel wilt so growers should check for these diseases before removing trees. Contact insecticides are ineffective because the insects are primarily inside the tree. One of the first goals to avoid infestation with the beetles by maintaining a healthy tree. Stressed trees are FEBRUARY 2018 | CAPCA ADVISER

Scouting for laurel wilt in commercial avocado groves Surveying for the symptoms of laurel wilt is a key component to limiting the spread of the disease. Growers and their workers should survey their groves weekly or more often if an infestation is detected in an adjacent grove. Pathogen sniffing dogs are currently being used in Florida, however there are less than half-dozen trained dogs for this purpose.

Sorghum Seeding Rates for California Grain Sorghum Production Michelle Leinfelder-Miles, Delta Farm Advisor, UC Cooperative Extension, San Joaquin County; Jeff Dahlberg, Director, UC Kearney Agricultural Research and Extension Center In recent years, the University of California Division of Agriculture and Natural Resources has augmented research efforts on growing grain and silage sorghum [Sorghum bicolor (L.) Moench] in California. The purpose of the Delta sorghum seeding rate trial was to better understand optimal seeding rates for grain sorghum grown in the Sacramento-San Joaquin River Delta. While such information exists for Midwest sorghum production, applied information is lacking for California, and more specifically for the Delta – a unique agricultural region known for its organic soils, shallow groundwater, and cooler climate conditions. This information is important because sorghum has similar growth habits as corn and is sometimes grown as a substitute for corn because of its tolerance of drought and low-input conditions. In the United States, sorghum is used in a wide array of feedstocks for biofuels, pet foods, dairy, cattle, pork and poultry feed, and more recently as a gluten-free cereal grain for human food systems. The trial took place during the 2016 and 2017 growing seasons on Tyler Island in Sacramento County. In 2016, the plot was established on a Rindge mucky silt loam, and in 2017, the plot was established on a Gazwell mucky clay. The 2016 trial was planted on May 20th, and the 2017 trial was planted on May 25th using a cone planter. Seed was planted approximately 2 inches deep. We used the grower’s varieties, which were white sorghum varieties having 16,000 seeds/lb and 85 percent germination, according to the labels. Five seeding rate treatments (5, 6, 9, 12, and 15 lbs/acre) were tested. Each plot consisted of four rows (30-inch row spacing) that were approximately 50 feet in length. The previous crops in the fields were wheat (2016) and corn (2017). The fields were managed similarly in both years. Subsurface irrigation by “spud ditch” was employed twice. (This is an irrigation method unique to the Delta where water is applied through ditches running parallel with the crop rows. Spud ditches are dug approximately 60 feet apart. Irrigation water moves down the spud ditches and laterally across the soil between spud ditches, drawing up shallow ground water to the root zone. With this method of irrigation, it is difficult to ascertain the amount of applied water.) The fertility program was 35 gallons/acre of 8-24-0 with ½ percent of zinc at planting. The field was cultivated one time, and bromoxynil and atrazine, plus adjuvant were applied for post-emergence weed control in mid-June. The plots were harvested on November 14, 2016 and October 12, 2017 using a research combine, harvesting the center two rows from the four-row plots.

Data were collected for plant establishment characteristics, plant maturity characteristics, and yield and represent mean values for the four (2016) or five (2017) replicates. The experimental design was changed from a Randomized Complete Blocks Design (2016) to a Latin Square Design (2017) in order to control field variability both down and across the rows. Tukeyâ&#x20AC;&#x2122;s range test was the statistical method used to compare the means. Treatments were considered statistically different if the P value was less than 0.05, or 5 percent. Differences among treatments are indicated by different letters following the mean. The seeding rates are expressed as plant populations in Table 1. The number of sorghum seeds/lb is highly variable across varieties. For this reason, when determining seeding rates, growers should first determine their desired plant population. Stand counts were made as the number of plants/10-foot row length approximately two weeks and one month after planting. The counts were scaled up to plants/acre. Across both years, stands generally decreased from the first count date to the second. Stand counts were lower in 2017 compared to 2016, but this did not translate into lower yields. Weeds were also counted in the month after planting (data not shown), but overall weed pressure was very low in both years. Sorghum bloom occurs when at least half of the panicle is shedding pollen (Fig. 1). There were no differences in the number of days to bloom among treatments in either year; however, there were differences among treatments in the other maturity characteristics (data not shown). In both years, plants in the higher seeding rate plots were taller and/or had longer panicle exsertion (the length of the stem from the top leaf to the bottom of the panicle), suggesting that at higher densities, plants were competing with each other and growing longer internodes. In both years, panicles were longest in the 5 lb seeding rate and statistically longer than the panicles in the higher rate treatments. There were no statistical differences in grain moisture at harvest in either year. In 2016, when harvest occurred later in the season, grain moisture at harvest averaged 17.9 percent across treatments. In 2017, grain moisture at harvest averaged 12.3 percent across treatments. In 2017, the weight of 1000 seeds

was also analyzed to understand whether certain treatments were producing heavier seeds. We found that the seed of the 6 lb rate had the heaviest weight and was statistically heavier than the 12 lb rate but not different from the other treatments. While there were no statistical differences in yield across treatments in either year (Fig. 2), the take-home message of the trial is that there appears to be no benefit to planting the highest seeding rates. In both years, the trend was for the 15-lb seeding rate to have the lowest yield. In 2016, there was a lot of variability in the data. There was a trend for the 9-lb treatment to have higher yield; however, we suspect this was due to the experimental design. In 2016, by random chance, there were several 9-lb treatment plots next to the sub-irrigation ditches, which were exterior to the

experiment on both sides. For this reason, the 9-lb treatment may have been inadvertently favored with better moisture conditions. To correct this, the experimental design was improved in 2017 by blocking in both directions, in order to better control field variability in the data analysis. The 2017 yields were consistent across treatments, around 7000 lbs/acre. The 2017 results best illustrate how planting the higher seeding rates provided no yield benefit, yet would incur a higher seed expense. We recognize that growers will need to consider site characteristics, like weed or wireworm pest pressure, when determining optimal seeding rates; nevertheless, this research indicates that good yields can result from seeding rates of 5 or 6 lbs/acre (estimated plant populations of 80,000-96,000 plants/acre), and that planting higher plant populations would not only cost growers more in seed expense but could also cost them in yield.

environment, and the research has applicability to grain sorghum production elsewhere in the state. The results indicate that there is no yield benefit to planting seeding rates greater than 6 lbs/ acre (estimated plant population greater than 96,000 plants/ acre), and that planting higher rates is just added expense for the grower. Future research should investigate these plant populations on narrower row spacing, as is done in other states. The researchers wish to thank the growers for their cooperation. More information on the trial, including a worksheet for calculating seeding rates from plant populations, is available from ucanr.edu/sites/deltacrops. █

In summary, it is important to study sorghum cultural practices in California because currently most applied information comes from the Midwest. California growers need information on sorghum cultivation because sorghum may be grown as a lowerinput substitute for corn.

Stinky in high numbers: What’s new with brown marmorated stink bug in California? Jesús R. Lara1, Charlie Pickett2, Beth Grafton-Cardwell1,3, Phoebe Gordon4, Joshua Reger3, Samuel Figueroa1, Mariana Romo1, Joshua Oliva1, Mark S. Hoddle1 University of California Riverside, Department of Entomology; California Department of Food and Agriculture; 3 UC Lindcove Research and Extension Center; 4 UC Cooperative Extension Madera 1

Brown marmorated stink bug (BMSB), Halyomorpha halys (Hemiptera: Pentatomidae), is an invasive stink bug native to Asia. Genetic analyses indicate BMSB populations in the U.S. originated from China (Valentin et al. 2017). BMSB is exhibiting growing potential for widespread economic damage to U.S. agriculture. This threat is reflected in the expanding geographic distribution of this insect and accumulating evidence of crop losses. Since the establishment of BMSB in the northeastern U.S. during the 1990s, it has now established in 44 U.S. states. BMSB has generated agricultural problems in 9 of these, most notably to the apple industry in Mid-Atlantic States (Leskey et al. 2012), and a mixture of emerging nuisance and/or agricultural problems in 21 other states, including Washington, Oregon, and California (NIC 2017). BMSB adults and nymphs pierce and injure plant tissue with their prominent needle-like mouthparts and more than 170 feeding and/ or reproductive host plant species have been recorded from the U.S. (NIC 2016). BMSB adults can overwinter in human-made structures, are strong fliers and excellent hitch-hikers with the ability to reach new areas. Consequently, the presence of BMSB in California is an emerging threat to the state’s multi-billion dollar agriculture industry. This concern has generated stakeholder support to develop proactive sustainable management options for this pest, one of which is classical biological control with egg parasitoids imported from China. What’s the problem in California? In California, BMSB was first detected in 2002 from Riverside County and has now been recorded from 34 counties, 15 with established populations and 19 others where continued monitoring should confirm if permanent populations exist (Fig. 1). Several nuisance cases from residential areas, arising from BMSB detections in backyard gardens and inside homes throughout the year, have been documented from California (Fig. 2). However, the pressing concern is with the movement of BMSB from urban centers to neighboring agricultural areas during the spring-summer growing season. Presently, there are no records of economic damage by BMSB to food crops in California, but recent field evidence suggests that BMSB has the potential to become problematic in some key agricultural areas.

CAPCA ADVISER | FEBRUARY 2018

In 2016, BMSB was detected in commercial ‘Cling’ peach acreage from Stanislaus County (Rijal and Duncan 2017). This is a concern because BMSB has already been documented attacking ‘Redhaven’ peaches in the eastern U.S. and this cultivar was shown to be susceptible to BMSB feeding (Joseph et al. 2015). Additionally, BMSB has been recorded from kiwifruit acreage (Butte County), almond acreage (Stanislaus County), and mixtures of backyard fruit (e.g. citrus, avocado) and ornamental host plants in urban areas (Sacramento and Los Angeles counties) (Lara et al. 2017; Daane and Rijal pers. comm.). Quarantine trials run at UC Riverside demonstrated that BMSB can injure developing ‘Kerman’ pistachios kernels and on-the-vine quality ‘Hayward’ kiwifruit, two important specialty crops grown in California (Lara et al. 2017). While chemical control is an option, applications are not always effective and there is concern that overreliance on chemical control could disrupt valuable pest control services provided by resident natural enemies (Kuhar and Kamminga 2017). Research is underway to develop a sustainable management strategy for BMSB in urban and agricultural habitats in California. These efforts include the expansion of BMSB monitoring to delineate its distribution and developing a biological control program. Keeping up with BMSB in the field The objective of BMSB monitoring is to track the spread and phenology of this insect with pheromone-baited pyramid traps (Fig. 3). The pheromone, held in a quart-size plastic collection jar on the top of the trap, is attractive to immature and adult BMSB (Khrimian et al. 2014). Stink bugs enter through the bottom of the jar, but cannot escape because of the cone-like funnel. The BMSB pheromone can also be paired with other trap designs like sticky panels that are staked to the ground or secured to branches. During 2017, pyramid traps with pheromone were deployed in Siskiyou, Butte, Sacramento, Santa Clara, Merced, Madera, Fresno, Tulare and Los Angeles Counties. BMSB have only been detected from Siskiyou, Butte, Sacramento, Santa Clara and Los Angeles counties as part of this monitoring effort. In Sacramento County, two generations per year are known to occur (Ingels et al. 2016). BMSB finds reported by the public in Southern California extend from the San Fernando Valley to San Diego, mainly along coastal areas (Fig. 1). No BMSB have been caught in traps deployed in the San Joaquin Valley, but these traps did assist with the detection of several resident stink bugs, including Euschistus sp., Chlorochroa ligata, Chinavia hilaris, and Tepa sp. Most recently, Dr. Kent Daane (UC ANR) detected BMSB from Fresno County suggesting that BMSB is becoming established further into the San Joaquin Valley, an area with significant agricultural production. As BMSB continues to spread and build within urban

centers, populations could make their way with greater frequency into agricultural areas. Biological control: What natural enemies attack BMSB in California? Biological control represents a promising approach to suppressing BMSB populations as it relies on predators and parasitoids to find and kill different BMSB life stages. Research by the University of California Riverside and the California Department of Food and Agriculture is taking two approaches. One is to take an inventory of stink bug resident natural enemies (Fig. 4) already present California that attack BMSB life stages (i.e., eggs, nymphs and adults). The second is to use a co-evolved natural enemy, an egg parasitoid imported from China, part of the home range of BMSB, for potential establishment in California. Generating an inventory of resident BMSB natural enemies has been possible with the use of sentinel egg cards. These cards consist of frozen BMSB eggs that are of excellent nutritional quality for predators and permit successful parasitism under field conditions

(Fig. 5). Species identification of collected specimens is still in progress, but the major groups of collected egg parasitoids so far have been Anastatus spp. (Hymenoptera: Eupelmidae) and plastygastrids (Hymenoptera). In some cases, deployment of these cards has been paired with time-lapse cameras to learn more about which animals can prey on BMSB eggs. Some carabids (Laemostenus complanatus), earwigs (Forficula auricularia and Euboreliia annulipes), cockroaches (Blatta orientalis), sac spiders (Trachelas spp.), and even rodents (rats) have been documented visiting egg cards in Sacramento County as part of these extended efforts. BMSB pheromone traps have also played an added role in detecting insects that attack mobile BMSB life stages. Two major insect groups sampled so far have been Euclytia sp., a parasitic fly (Diptera: Tachinidae) that lays eggs on the external body of stink bugs, and a predatory wasp Astata sp. (Hymenoptera: Crabronidae). Astata females capture and kill stink bug nymphs and adults and take them to underground nests to feed their offspring. The prospect of using these resident natural enemies for augmentative releases or conservation biocontrol to control BMSB in California is unclear, but is under investigation in other parts of the U.S. (Biddinger et al. 2017). Classical biological control: Specificity for BMSB is key In California, another complementary solution would be to develop a classical biological control program using key BMSB natural enemies, especially egg parasitoids from China. Significant progress has been made in this research area. Foreign exploration by USDA researchers recovered several candidate BMSB parasitoids from Asia. Among them is the egg-parasitoid Trissolcus japonicus (Hymenoptera: Platygastridae), the samurai wasp, from China (Fig. 6). Samurai wasp females lay a single egg within each BMSB egg. Wasp larvae feed on and kill the developing BMSB nymph. This egg parasitoid is the most important BSMB natural enemy in China (Lan-Fen 2007; Zhang et al. 2017). Interestingly, the samurai wasp has self-introduced itself into western (i.e., WA, OR) and eastern parts (i.e., DC, MD, VA, WV, DE, PA, NJ, NY) of the U.S., but it has not been detected in California. Sentinel BMSB egg cards deployed in California may detect the samurai wasp. FEBRUARY 2018 | CAPCA ADVISER

FARM ADVISORS, CONT., Stinky in high numbers: Whatâ&#x20AC;&#x2122;s new with BMSB in California?

Currently, host specificity of the samurai wasp is being evaluated under quarantine laboratory conditions at UC Riverside. The results from quarantine safety testing indicate that the host range of the samurai wasp is not restricted to BMSB. Seven of eleven native pentatomid species from California experienced some level of successful parasitism by the samurai wasp. Nevertheless, laboratory results also show that the samurai wasp has greater parasitism success on BMSB, and these results are encouraging. Supporting evidence of this assessment also comes from safety testing evaluations that focused on eight nontargets occurring in the home range of the samurai wasp and BMSB in northern China (Zhang et al. 2017). In that study, seven out of eight non-targets were successfully parasitized by the samurai wasp under laboratory conditions. Field studies in China suggested that some non-targets exposed in the lab may experience similar or relatively low levels of parasitism by the samurai wasp compared to BMSB. Thus, it is important to understand that lab studies alone that provide candidate natural enemies with maximum exposure to non-target hosts may not entirely predict the risk to nontarget populations under field conditions. In California, the self-introduction of the samurai wasp, should it occur, will warrant field studies to study its ecological host range to validate the conclusions from quarantine trials. In conclusion, BMSB has potential to be a significant agriculture pest in California. At this time populations are largely confined to residential areas and it is likely that BMSB will continue to migrate from these areas into agricultural production zones. Resident natural enemies may be able to provide some control of BMSB, but we anticipate that significant population reductions could be achieved with the samurai wasp, an egg parasitoid that evolved with BSMB in China. We are continuing to work on this parasitoid for BMSB biocontrol and will continue to provide future updates on this pest and its natural enemies. If you find BMSB in your area, please report it to your local Agricultural Commissionerâ&#x20AC;&#x2122;s office. You can also contact the authors of this article for more information.

Special to the Adviser

The Biochemicals of the Biopesticide World By Tim Damico, Executive VP-North America, Certis USA

Biopesticides are used more often in fruit and vegetable production than in any other crop group. In these specialty crops, managing the development of pest resistance is a primary concern for PCAs who need to avoid relying on products with similar modes of action. Biopesticides, with their complex modes of action, are especially important tools that prevent or delay the emergence of resistant pest populations. A class of biopesticides—the biochemicals—represent a wide array of active ingredients that are unique from the more common microbial-based biopesticides and also feature novel modes of action. These materials also play a valuable role in resistance management programs and sustainable pest management strategies. The Biological Products Industry Alliance (BPIA) defines four categories of biochemicals used for their pesticidal properties: Insect growth regulators, organic acids, plant extracts and minerals/other. Insect Growth Regulators (IGRs) IGRs, generally, prevent insects from reaching a reproductive stage, thereby reducing the expansion of pest populations. Azadirachtin is one of the most widely used botanical IGRs. Because of its structural resemblance to the natural insect molting hormone ecdysone, azadirachtin interrupts molting, metamorphosis and development of the female insect reproductive system. Immature insects exposed to azadirachtin (mainly by ingestion) may molt prematurely or die before they can complete a properly timed molt. Those insects that survive a treatment are likely to develop into a deformed adult incapable of feeding, dispersing or reproducing. Organic Acids Organic acids include fatty acid active ingredients and the peracids. Potassium salts of fatty acids, commonly referred to as insecticidal soaps, contain long-chain fatty acids that control soft-bodied insects and arthropods on contact. The fatty acids penetrate the body of the pest and disrupt its cell membranes causing the cell contents to leak out. The insect dehydrates and dies. Short-chain fatty acids have herbicidal effects and are manufactured as herbicides (ammoniated soap of fatty acids). These materials are fast-acting control measures that desiccate and dehydrate weeds, grasses, algae, lichens, liverworts and mosses.

CAPCA ADVISER | FEBRUARY 2018

Peracids are highly effective sanitizing agents used for control of pathogens and algae. Also called activated peroxygen, peracids use hydrogen peroxide as their base component combined with organic acids, typically acetic acid. This forms a new compound called peroxyacetic acid (PAA). This new activated form of hydrogen peroxide produces a stable and powerful oxidizing compound to treat pathogens and algae in water. The PAA mode of action is by oxidation of cell membranes and penetration into cell structures of algae, bacteria and fungi. More specifically, PAAs form free hydroxyl radicals (OH), which oxidize and disrupt thiol groups in proteins and enzymes. Plant Extracts Plants are natural laboratories in which a great number of chemicals are biosynthesized. Many plants have developed natural, biochemical mechanisms to defend themselves from weed competition and animal, insect and fungal attacks. Some of these biochemicals discourage feeding by insects and other herbivores. Others provide protection or even immunity from diseases caused by some pathogens. Still others help plants compete for resources by discouraging competition among different plant species. Naturally found in chrysanthemum flowers, pyrethrins are a mixture of six chemicals classified as terpenoids that have insecticidal properties. Pyrethrins target the nervous systems of insects. Upon contact or ingestion, they disrupt a pests’ sodium channels. Hyperexcitation of the insect nervous system follows, leading to paralysis and death. The oil of the neem tree, indigenous to the arid regions of India, yields the IGR azadirachtin and another biochemical: clarified hydrophobic extract of neem oil. Neem oil is a botanical fungicide and miticide. It works as a protectant to prevent infection of plant tissues by preventing the germination and penetration of fungal disease spores on the leaf surface. It also eradicates light infestations by desiccating the spores and mycelia present on the leaf. The biochemical neem oil also works as a knock-down material for mites. The plant extract category also provides materials that induce resistance (IR). Crops treated with these plant extract biochemical produce and accumulate elevated levels of specialized proteins and other compounds that inhibit the development of fungal and bacterial diseases. In effect, they trigger the crop’s immune system to defend itself against destructive diseases.

As of April 2016, there are 299 registered biopesticide active ingredients and 1401 active biopesticide product registrations. Source: US EPA.

Minerals/Other Minerals are the mechanics of the biochemicals. Some create barriers to keep pests from plant tissues and/or to impact a pathogen’s water supply, to deliver physical impacts such as smothering or abrasion of the pest, or act as an inert carrier for companion biologicals. Kaolin clay is an example of a biochemical that creates a physical barrier between insects and plant tissues. It acts as a repellent that coats the plant surface and makes it unsuitable for insect feeding and/or egg laying. Kaolin also breaks off in small particles that attach to insects, agitating and repelling them. Potassium silicate is another mineral biochemical. It works as a desiccant to soft-bodied insects and mites and creates an amorphous silicon layer within the leaf tissues to prevent the penetration of fungal pathogens.

Case Study: Aphid Control on Lettuce Due to their unique mode of action, biochemical insect growth regulators (IGRs) are in use in the Salinas Valley to manage resistance. Due to restrictions placed on certain crop protection products, the lettuce industry has relied on the use of contact and systemic control measures—some with overlapping modes of action—which creates concern for pesticide resistance. Integrated use of azadirachtin provides control by impacting the larvae and nymphs of multiple aphid species, breaking the life cycle before they become reproducing adults.

Case Study: Pear Psylla Control on Pears Biochemicals excel when they are used in conjunction with multiple types of pesticidal approaches. Pear growers find that they can maximize the effectiveness of their pest management programs for pear psylla by integrating the use of traditional control products, the biochemical azadirachtin and the biochemical product kaolin clay.

Diatomaceous earth (DE) combats insect infestations through abrasion. DE contains fossilized microscopic plants that give the biochemical compound sharp surfaces that cut through insect exoskeletons, a process that leads to the desiccation and death of the insects. Mineral oils smother insect pests in nesting stages.

Case Study: Greenhouse Sanitation

Mineral biochemicals are also used as inert carriers for companion biologicals. Minerals included in formulations deliver or enhance pest control materials, but the mineral itself is considered an inert ingredient. Examples of these mineral types include montmorillonite, attapulgite, kaolin and talc, all of which have physical structures that allow biopesticides to be carried on them, often in powder or granular forms. █

Peroxyacetic acids (PAAs) are used for sanitation of greenhouse surfaces, shock applications for tanks and piping, and as bactericidal and fungicidal applications to plant foliage or roots.

IN MEMORIAM

Linda Pangle LaVanne Linda Pangle LaVanne passed away on November 10, 2017. Linda was born in Calexico, California on October 16, 1956. She graduated from Mountain Empire High School in 1974. Following her love of horses, she earned her degree in Animal Science from The University of Arizona in 1978. Linda was part of the inaugural concentration in Race Track Management. She worked several tracks in the west in Spokane, Phoenix and Tijuana. Her work ethic and competence earned her the distinction of becoming the first female official at Agua Caliente in Tijuana. In 1983, she changed careers entering into the agricultural animal and plant protection industry with ICI Americas. Her first assignment was in Louisville, Kentucky where she met her husband Tom. They moved to Westlake Village, California in 1984 when ICI offered her a technical sales position in a territory covering the California coast from San Diego to San Luis Obispo and Hawaii. Over the next 33 years with ICI, Zeneca and Syngenta, Linda built a broad following through her commitment to her customers, colleagues and to agriculture. Linda served as CAPCAâ&#x20AC;&#x2122;s State Chair (1993-1994) and participated for many years as an advisor to the State of California Agricultural Pest Control Advisory Committee (APCAC) on behalf of all PCAs. As a loving wife to Tom and mother to their children, Christine and Paul, she balanced a very demanding job with making time for volunteerism in school activities, Scouting and church. Linda had an infectious smile, an unmistakable laugh and an outgoing, engaging and considerate personality. She was witty, smart and compassionate. No matter what, she always committed herself to excellence at home, at work and in the community. For this and more, she is a profound loss to this world and will be adored and fondly remembered by all those fortunate people who knew her. â&#x2013;&#x2C6;
