AT THE CENTER OF PLANT HEALTH

From the Editor Enduring and Advancing: Member Engagement CAPCA has been marching towards change for a while now. Some of CAPCA’s most influential members are retiring and stepping down from leadership positions. The insight, historical knowledge and professionalism that built and sustained CAPCA for so many years is stepping aside to make way for the next generation. These retirements hit me with mixed emotions as the leaders who were foundational for me when I joined CAPCA five years ago will no longer be just a phone call away. Those who built and established CAPCA’s reputation have had an incredible impact on how I approached telling the story of the PCA nearly three years ago when I took over as CEO. But I am also optimistic as I watch the reins being passed to new leaders with innovative ideas and fresh vision for our industry. This bridging phase, between the next generation of PCAs, fresh ideas and methods, and the retiring generation representative of the values that built CAPCA, is not unique to CAPCA. Other associations are also grappling with this same transition. The implications of the 2015 demographic survey, the healthy push from the CAPCA Forward Committee to continue our relevance as a source of information, the cultural climate and ever-present expectations to do more with less, continue to add pressure to our industry. CAPCA leadership has responded to each of these as opportunities to evolve and educate through joining the team of agriculture and engaging in proactive ways. In 2017, rebranding brought a fresh visual image and packaged talking points to the Capitol, members and industry at large. Our message is focused on PCAs not only being the Plant Doctors, but at the center of plant health. With the rollout of a more dynamic website last year, we created additional opportunities to connect with our membership online – which may strategically decrease our paper footprint over the coming years as we release unofficial certs, chapter information and membership reminders through the CAPCA website. The intention of these changes is to help serve new PCA members, but rest assured the CAPCA state office is just a phone call away for our members who still want to connect with a live person. At this month’s CAPCA board meeting, I challenged directors to look forward 5, 10 years to consider where we go next, how we best serve the membership with our resources, and what role the chapters and the state office play in executing that vision. Because, at the core, we remain a membership driven association, making decisions to best serve all our membership. █ Ruthann Anderson, Editor ruthann@capca.com

LEADERSHIP

Politics is Never Easy By Rick Wescott, CAPCA Chairman

So here we are in the middle of an election year that will be very pivotal for agriculture and the green industry going forward. As you know, the current administration has not been very friendly to agriculture and our jobs as PCAs. There has been a constant onslaught of legislation and CDPR decisions that make our jobs, and our growers' jobs, difficult to say the least. In November there will be a change in administration with the election of a new governor and, depending on who is elected, could be better for agriculture, or much worse. Let’s take a look at the scenario that is before us: It could be a race between a Democrat and Republican or two Democrats. The most likely scenario based on the latest polling is that in November we will be choosing between two Democrats. So on the one hand you have a very left wing “D” that makes the Brown administration look like a moderate, and on the other hand you have a “D” that is somewhat closer to being moderate though still leaning to the left. So what does all this mean for CAPCA and Agriculture? The fact is, of the two Democrats, only one has reached out to agriculture and has taken an interest in us: Antonio Villaraigosa. The majority of Agriculture, including CAPCA, is supporting Villaraigosa for governor of California. He understands the water issues, labor and the loss of crop protection tools, and is willing to work with team agriculture to help solve these issues. He has sat down with many Ag groups to discuss his plans and willingness to work with us. We will not agree on every issue, but the alternative choice isn’t even in the same ballpark. One thing is certain: You have to make a choice based on the facts and information presented. CAPCA has made its choice to be a part of the solution and take a stand for what is right! Now get out and vote. Your future may depend on it! █

HUANGLONGBING

The Growing Threat of Huanglongbing and How You Can Protect California Citrus The Asian citrus psyllid (ACP), a vector of the bacterium that causes Huanglongbing (HLB) disease, has been identified in southern California. Vigilant pest control is necessary to protect California citrus from the severe effects of HLB. HLB is the most devastating citrus disease worldwide and threatens all commercial citrus production. Florida has lost 72% of its citrus production since 2005/2006 as well as 119,000 acres of citrus trees and $674 million since the rise of ACP. In the U.S., 3.2 million metric tons of citrus were lost due to ACP.1

What’s at Stake for California Growers? California represents 41% of U.S. citrus production with 270,000 acres of citrus valued at $2 billion. According to California Citrus Mutual, 32 infected trees have been found in Southern California.2

ACP and Insect Management Options from Bayer Bayer has a proven portfolio of insecticides that provides the foundation for season-long ACP control and controls other important California citrus pests. Bayer’s portfolio encompasses multiple modes of action to limit insecticide resistance and is flexible relative to application timing and method to optimize crop quality and to help growers stay ahead of Huanglongbing.

How ACP Affects Citrus Plants

The psyllid damages citrus directly by feeding on new leaf growth (flush).

More importantly, the psyllid is a vector of the bacterium, Candidatus Liberibacter asiaticus (CLas), that causes HLB and transmits the bacteria into the phloem when it feeds on flush.

HLB disease spreads from tree to tree when a bacteria-carrying psyllid flies to a healthy plant and transmits the bacteria as it feeds on the leaves and stems.

The bacteria multiply in the tree’s phloem tissue, blocking the flow of nutrients through the plant. If not well managed, trees will eventually die within 3 to 5 years.

Effective control of Asian citrus psyllid reduces the chance that a citrus tree will become infected by the bacteria and helps ensure a healthy, productive tree.

Make Bayer’s proven portfolio a cornerstone of your insecticide program to help ensure tree protection and productivity with season-long control of ACP, as well as other key citrus pests.

GOVERNMENT

Government Relations Update by CAPCA Staff In 2017, a unique coalition came together to draft and promote a water initiative, statewide in scope, to address a wide array of water quality and water infrastructure issues. The coalition includes agriculture, water, conservation, environmental, and labor groups. On April 25, 2018, the first phase of the coalition’s work was achieved. The Secretary of State has announced that there are sufficient valid signatures to place the initiative on the November 2018 ballot measure entitled the Water Supply and Quality, Watershed, Fish, Wildlife, Water Conveyance, and Groundwater Sustainability and Storage. Specifically, the bond will authorize $8.877 billion in state general obligation bonds for various water infrastructure projects such as $3.03 billion for safe drinking water and water quality, $2.895 billion for watershed and fisheries improvements, $940 million for habitat protection, $855 million for improved water conveyance, $685 million for groundwater sustainability/storage, and $472 million for surface water storage/ dam repairs. On May 3rd, the CAPCA State Board of Directors voted to endorse the Water Bond Measure slated for the fall ballot. Well over 200 organizations have endorsed the bond and many more are expected to add on in the next several months. (More information can be found by following the link in the QR code at the end of this article.) Along with joining coalition opportunities, the Government Relations Committee has set clear priorities for engagement in 2018 – the goals of the committee along with promoting the value of the PCA license and protecting the tools in the toolbox for PCAs to use in IPM include: • Active Ingredient Defense – writing comment letters on AI under review and joining coalition letters by offering perspective on use and impact to crops from the boots on the ground PCA. • Nitrogen Management – working on Nitrogen issues generally (see Water Bond above) and how to manage liability specifically for the CCAs who are signing off on Irrigated Lands, Nitrogen Management Plans. CCAs cross over with the PCA license is still around 82% for California. • Cannabis – although the CAPCA State Board issued a statement last fall in opposition to PCAs writing off label recommendations for Cannabis, CAPCA GR Committee has been committed to staying at the table with stakeholders to help explore solutions.

CAPCA ADVISER | JUNE 2018

• Pollinator Protection – CAPCA has led the way in the Bee Where project and in support of AB 2468, including testifying at a recent Assembly Ag Committee Hearing. This issue has been a great opportunity for CAPCA GR Committee to re-introduce the CAPCA brand to lawmakers and regulators as we have brought together the industry to address the communication between stakeholders that starts with registration of bee hives during pollination.

On May 3rd, the CAPCA State Board of Directors voted to endorse the Water Bond Measure slated for the fall ballot. • Legislative Outreach by Chapters – the Sutter Buttes, TulareKings and NorCal Chapters have recently visited with local legislators. These visits have provided CAPCA Chapters a new purpose in advising legislators on local issues and reinforces the relationships that CAPCA is building at the State Capitol in Sacramento with feedback and relationships direct from constituents. As efforts from the state office and committeelevel continue to gain momentum, we are excited to hear about more local chapters and individual members engaging with their representatives. If you are interested in coordinating a visit for your chapter and not sure where to start, contact Ruthann Anderson for assistance. █

PCA PROFILE

Kristina Short: A Passion for Agriculture and PCA Advocacy By CAPCA Staff Kristina Short graduated from California State University, Chico with a Bachelor of Science degree in Agriculture and Plant Science. In addition to her PCA license, which she obtained in 2009, Kristina also holds a QAL. The major crops she consults in are tree nuts, wine grapes, stone fruit, pome fruit, grains and berries. She began her career as an intern working at the rice experiment station on weed control projects, and from there went on to work for Helena Research and Development where she learned more about pathology, entomology, weed control, and plant nutrition by conducting trials. In her current position with Westbridge Ag Products, she continues to learn about organic farming and new ways to solve crop management problems in the field using organic products. Her territory covers Chowchilla to Oregon, and Kristina meets with PCAs and growers, providing technical advice and assisting with solving problems in the field. “I have a lot of respect for PCAs who are walking fields every day, and I love getting to spend time with them creating crop programs and solutions.” She also works one-on-one in the field on plant nutrition, pest control, and IPM. But her interest in agriculture and being a PCA began early in life. “I guess you could say I’ve always wanted to be a PCA from a young age, but I just didn’t know what it was yet. I have always had a fondness for agronomy and learning more about plants. I learned a lot from my grandfather about farming and hard work in the field, and my passion grew from there. I decided to focus on agriculture since I knew it was my passion.” She credits all of her experiences in the industry–from 4H, college and each job along the way–with providing lessons that have put her on her current career path. “I have always been a problem solver and love that I get to mix my love of the outdoors and farming with my love of solving problems.” Building relationships within the industry is also a personal highlight for Kristina. When asked about advice for those considering the career or those new to it, she replied, “If I had to give any advice to young PCAs getting started, it would be to work while you’re going to school and start building relationships; they will be so crucial in building a career. I would also suggest finding a mentor to help guide you in your field knowledge and also in your relationship-building skills… Some of the most satisfying highlights I’ve had so far as a PCA have been the relationships I’ve made with other PCAs, researchers, and growers all over the state. I learn something new and exciting every day, and I love that that knowledge gets to come straight from the hard-working people in the field.”

The Grower’s Advantage Since 1982 JUNE 2018 | CAPCA ADVISER

When talking about the value of her CAPCA membership, Kristina is candid about why she initially joined: “As soon as I got my PCA license I signed up to be a CAPCA member. Originally, I just saw CAPCA as a means for tracking my hours. As I’ve grown into my career, I’ve realized that attending the local chapter meetings is a great resource for connecting to other PCAs in my area and for getting updates from the Ag Commissioners in our area. We are very fortunate to have the local county advisors at our monthly meetings and I enjoy their updates and information.” Kristina is a member of the NorCal Chapter and serves as their Vice President: “I was nominated to volunteer by another chapter board member, and I couldn’t be happier I was asked to get involved.” Her involvement with CAPCA also includes the Government Relations Committee and advocacy initiatives. “I am so excited to see CAPCA wanting to get more involved with our local government affairs. I think that, as an organization, we are very fortunate to have PCAs all over the state of California, and that if we can all meet with our local assemblymen, senators, and state representatives, we can create a united message and presence.” Asked about the NorCal Chapter’s recent advocacy event, Kristina shared about meeting with Colin Sueyres, the legislative director from Senator Jim Nielsen’s office, in early March at the State Capitol in Sacramento, along with fellow Chapter members Manny Salazar, JR Gallagher and Doug Elrich: “Prior to our meeting, we had lunch with Ruthann Anderson and George Soares. We had a great meeting with George and are so happy to have him representing CAPCA. Our meeting with Colin was very positive and he was very supportive of our industry and eager to learn more about what a PCA is and what CAPCA represents. We really wanted to build a relationship with Senator Nielsen’s office so we could have a future back-and-forth communication between our CAPCA chapter and his office. We touched on topics such as: What a PCA is, product registration, bee safety, recommendations, spraying around schools, water storage, nutrition, IPM, and crop diversity in our area. We plan to follow up with Colin after our chapter meetings and keep him in the loop with what’s going on in our area. He also seemed interested in reaching out to us when topics come up [where] he feels a PCA’s expertise is needed. I highly recommend other chapters try and setup a meeting with their local legislator. It was a valuable meeting and relationship for our Chapter.” Considering CAPCA’s future, Kristina is excited to see continued growth and involvement for local PCAs with state legislators to keep them informed and be an industry resource. “I would also like to see CAPCA become a talking voice for PCAs to better inform people who aren’t in our industry about what we do. I often think the general public is misinformed, or doesn’t understand all the effort PCAs take to make good IPM decisions. If our association could educate the general public on all the decisions we try to make as PCAs for what is best for our environment, I think it would be a great benefit.” █

PATHWAY TO PCA

Pathway Visits to Colleges: Central Coast and SoCal Chapters Ariana McCray, So. California Representative The Central Coast Chapter hosted a “Night with PCAs” event at Cal Poly on Thursday, April 26. Students sat down with groups of PCAs to hear about their job responsibilities and the many ways a PCA license can be used. Students had the chance to ask questions, and Chapter members gave advice on what subjects to focus on or skills that have helped them throughout their careers.

CAPCA ADVISER | JUNE 2018

The SoCal Chapter has also participated in Pathway to PCA events at Cal Poly Pomona and Mt. San Antonio College in February and April. It’s great to see the interest in the PCA profession that students have! Pathway to PCA would like to thank the Central Coast and SoCal Chapter for their participation in these events! █

Managing Mites:

Protection from the Unpredictable “Nealta® miticide provides a unique class of chemistry for strong knockdown power and residual control of spider mites at all life stages.” - Leigh Ann Harrison BASF Technical Service Representative Summer will soon be underway and so will the summer pest protection programs of California almond growers. One thing that can lead to an increase in insect pressures for growers are weather patterns that produce the ideal conditions for insects to survive. As a pest control advisor, you have the knowledge to make recommendations that help your customers protect their orchards, no matter what weather conditions or insect pressures they may face. Leigh Ann Harrison, BASF Technical Service Representative, shares some beneficial advice to help growers make the most of their pest protection programs.

weather patterns. Establishment of a consistent pest management plan helps growers control mite populations before they take over an orchard should mite pressure increase. “Nealta miticide is specifically formulated to be compatible with many beneficial insects, while controlling spider mites at all life stages, including eggs,” said Harrison. Another important consideration for growers is the application timing of miticides. Harrison notes that BASF recommends applying Nealta miticide at or before local action thresholds, including a preventative treatment recommendation.

“Although it’s impossible to predict exactly what type of weather growers will face throughout a summer, it’s better to have a plan in place before insects can have a major impact on a crop,” said Harrison. “Not only does this lessen the effect on crop yield and quality, but it also gives growers a sense of security.”

“No one can accurately predict the weather, but everyone can implement a solid pest management plan to handle whatever complications occur,” said Harrison. “An orchard is a long-term investment, with its success depending on the longevity and health of a grower’s trees, regardless of weather conditions.”

The spider mite is one pest almond growers are particularly familiar with. This pest’s populations depend highly on

2018 CAPCA Spring Summit Recap CAPCA Spring Summit April 24-25, 2018 April 24th was the start of the second Annual Spring Summit held at the Pechanga Resort in Temecula, California. The Spring Summit is a new conference that CAPCA is providing for those PCAs whose growing season does not allow them to attend our Annual meeting in October. This yearâ&#x20AC;&#x2122;s summit offered attendees indepth discussions on some of the critical issues faced by Southern California and the desert region. We also provided a tour of the UC Riverside Agriculture Experimentation Station. The show kicked off in the afternoon of the 24th with presentations from Dr. John Kabashima, Dr. Jesse Richardson, Mr. Steve Koike and Mr. Bob Atkins. Each presenter shared insight on their specialties as they relate to the local area. Then it was on to the Welcome Reception, where attendees visited with our Exhibitors and sampled wine from a local vineyard. On Wednesday, we began the morning with an update from Mr. Jahan Motakef of DPR's Southern Regional Office. Then the attendees broke into two smaller groups: one stayed on property to enjoy a collegiate lecture-style workshop and the other group was bussed off to UC Riverside for a tour of the Experimental Station. After lunch, the program was repeated so that everyone could participate in both learning opportunities.

Mr. Rick Wescott, the State CAPCA Board Chairman, addressed the assembly at lunch and shared updates on what CAPCA has accomplished this year. Overall, this was a great meeting, with attendance increasing by 25% over last year. Attendees loved the newly renovated rooms and conference center at the Pechanga Resort. The Board has decided to hold the Summit again next year at the same location. Look for dates in the next issue of the Adviser. â&#x2013;&#x2C6;

Two of the most common questions received are: ‘will AgroLiquid products really work at the “low rates” for many years,’ and, ‘can they do this without mining nutrients from the soil’. In an effort to answer those questions, the North Central Research Station (NCRS) has been proving AgroLiquid’s product performance for over 20 years.

Special to the Adviser

Focus On Fruit Quality by Carlos Palavicini, AgroLiquid, Sales Account Manager One of the most important concerns of every grower, PCA or CCA, is how to get the best quality of any crop. In my experience, achieving consistently high quality is a challenge - and it is a different challenge for every crop and every grower. Because, when we are talking about quality, we can be referring to many things, like flavor, color, brightness, size, firmness, shelf life, etc., and all these characteristics mean one simple thing for the grower: profit. So, when we are talking about quality of the fruit, we are talking about how much the grower will make at the end of the season, sometimes when the crops struggled along the season with different vectors that are affecting the yield (quantity), what can save the season, and the investment, is the quality. Of course on the ideal world, what we want is the right balance between the "best yield" and the "best quality." Nutrient management in the plant after flowering is critical to achieving the quality goals on any operation. In this first in a series of articles, we will look at some of the nutrients that can directly affect plant health and fruit quality. Potassium (K) The essential roles of potassium are the synthesis of protein, photosynthesis processes and the transportation of sugars from leaves to fruits. From the early stages of the plants, a right amount of potassium will help the leaf in its role to growing fruit in later stages, and it will contribute to the positive effect of potassium in the yield and in the high content of total soluble solids (TSS), which means more sugars in the fruit, at the time of harvesting. Sixty to sixty-five percent of the potassium absorbed by the plant can be found in the fruit.

CAPCA ADVISER | JUNE 2018

Potassium is a cation that is involved in the maintenance of the osmotic potential of the cell, an implication of this is the movement of the stoma. The stomatal opening allows the plants to exchange gas and water with the atmosphere. This allows the plants to maintain adequate hydration under stress conditions such as high salinity or water shortage. For instance, a tomato crop with good or high levels of potassium will show a greater efficiency of water use. This means that these plants can consume less water and will generate the same amount of biomass than plants with less potassium content. One of the most important consequences of potassium management is the fruit maturation processes, such as the synthesis of the lycopene pigment, which is responsible for the color of the fruits. Potassium also promotes a high acid content, which is essential for a good tasting fruit. Calcium (Ca) Calcium is part of the salts in the soil solution. Calcium is absorbed by plants in Ca ++ cationic form and has little mobility within the plant. Calcium is a critical component of plant cell, it is an important component of the middle cell lamella, maintaining the structure of cell walls, and stabilizes their membranes. It also has a direct influence on the balance of salts within the cells, regulating its osmotic pressure, and activates the potassium that adjusts the opening and closing of the stomata for transpiration of the plant. Calcium promotes the germination of pollen, adjusts some enzymatic systems, and influences the growth and health of cells and conductive tissues. It is the key element in the development of shoots and roots (meristems), and in the absorption of nitrates. In addition, calcium is associated with the processes of fruit ripening.

When talking about quality of the fruit, all those functions will be reflected in adding shelf life to the fruit. Magnesium (Mg) Magnesium is a central element in the chlorophyll molecule. Between 15 to 25% of the total magnesium is located in the chloroplasts. It is responsible for the production of enzymes for various biochemical functions, such as energy transfer and protein synthesis. Studies have found that the use of magnesium at fructification helps to improve some quality characteristics of fruits in crops like tomatoes, grapes, pineapple, papaya, and apples. Those studies suggest the magnesium collaborates in transporting the sugars from the leaves to other areas of the plant. It is very important to always be careful on the ratio Ca:Mg, high levels of magnesium can block the Ca and therefore have negative affects on the quality of the fruit (i.e. it can induce bitter pit in apples, or blossom-end rot in tomatoes).

Micronutrients Micronutrients are often forgotten when talking about fruit quality. Often, the micros that get the most attention are iron and boron. Usually, this is to either avoid chlorosis or to improve the flowers. However, zinc is also an important micronutrient because it helps maximize the development of new tissues in fruits. When applied with phosphorus, zinc promotes the development of the root in the early stages of cultivation. Copper will help to avoid cracking of the fruit. A good blend of micronutrients is necessary to properly manage for quality fruit. In the next issue of the CAPCA Adviser, we will look at some of the environmental factors and cultural practices that can affect nutrient uptake in the plant – and therefore fruit quality and grower profit. █

My personal experience in the field has shown that a controlled application of Magnesium will help in the brightness, color and weight of the fruits.

The Virulent Viruses: Codling Moth Virus and Its Role in Pest Management Michael B. Dimock, Ph.D., Certis USA Vice President of Field Development & Technical Support Codling Moth Virus CpGV is a naturally occurring virus that infects and kills larvae of the codling moth (Cydia pomonella). The scientific name for this beneficial virus is Cydia pomonella granulovirus or CpGV. It is also known as the codling moth granulosis virus. Widely used in apple and pear production, CpGV can be used on conventionally grown, as well as organically grown crops. It has a four-hour restricted entry interval and is exempt from the requirement for a residue tolerance, meaning it can be applied up to and including the day of harvest. Mode of Action Each CpGV virus particle is naturally microencapsulated within a protein occlusion body (OB). Each OB measures about 400 x 200 nanometers, meaning about 4,000 OBs placed end to end would span only about 1/16”. A codling moth larva must ingest the OBs to become infected with the virus. The highly alkaline environment of the larval digestive tract (where pH can be as high as 10) dissolves the OBs and releases the virus, which penetrates the cells lining the midgut. Once inside, the viral DNA “hijacks” the nucleus of the cell causing it to replicate numerous copies of the virus which rapidly spread the infection to other organs. Within a few days, the infected larva stops feeding, becoming sluggish and discolored as its internal organs fill with virus. Upon death the larva “melts,” its fragile outer skin disintegrating to release the liquefied remains of its internal organs that now contain billions of new virus OBs. Each OB is capable of initiating a new infection if ingested by another codling moth larva feeding at that site or wherever OBs have been deposited by raindrops, gravity or by spraying CpGV. Studies show that a dose of one or two OBs is all that is required to cause a lethal infection in codling moth larvae. A single ounce of CpGV can contain nearly one trillion OBs. While not every OB in a CpGV spray will be ingested by a codling moth larva, the extremely virulent nature of CpGV toward its host means that it is effective at very low use rates. Transmission of CpGV CpGV occurs naturally in codling moth populations, but usually at levels too low to prevent damaging outbreaks in commercial orchards. The virus can persist for years in protected environments such as soil and leaf litter on the orchard floor or in tree cavities. Rainfall, wind, cultivation, movement of animals and birds, and other physical forces can move OBs onto foliage or fruit where

they can be ingested by codling moth larvae to begin another cycle of infection. However, the most effective way to initiate CpGV infection is to spray the virus onto the tree in much higher amounts than would otherwise occur naturally. Once CPGV infection has occurred within a larval generation, there are several ways it can be maintained within the codling moth population. Horizontal transmission occurs when larvae become infected by ingesting virus released into the environment when diseased larvae die. Sometimes infection occurs too late and at too low a dose to kill a larva outright, even though the virus has entered the host cells. A female that survives this sub-lethal infection may transmit the virus to her offspring, a process known as vertical transmission. In some cases a latent infection can occur, in which the virus lies dormant in the host until stress brought on by overwintering, overcrowding, lack of food or insecticide exposure causes and outbreak of virus that kills the host. Latent virus can kill host insects even years after initial infection. Timing and Applications Upon hatching, codling moth larvae wander in search for a spot to penetrate fruit, usually within a day or two after hatching. They may drink water droplets and feed on foliage if no fruit are available, but most don’t eat until after they enter the fruit and typically do not ingest the skin of the fruit when making an entry hole. Since CpGV must be ingested by the larva to be effective, optimal application timing for CpGV requires the virus to be present whenever small larvae are wandering on foliar or fruit surfaces seeking a penetration site. Virus picked up on the larva’s body and mouthparts will contaminate its feeding site and infect the larva when it starts to feed. CpGV applications should therefore coincide with egg hatch and this early wandering phase of newly hatched larvae. First Timing CpGV must replicate within the host larva in order in order to be effective, so CpGV is slower to kill larvae compared to many chemical insecticides having a toxic mode of action. Virus-infected larvae may still cause superficial “sting” damage where they attempt to enter the fruit, but they usually die before causing the deeper entry wounds that make fruit unacceptable for harvest.

CAPCA ADVISER | JUNE 2018

Forest and shade trees

Initial CpGV applications can be targeted against the first summer generation of larvae; a low level of early and superficial damage can be tolerated in most orchards and in many cases will be taken care of by thinning. Establishment of CpGV infection in the first generation may also carry over into later generations, making them easier to control with other tactics. When targeting larvae of the first summer generation (late May to mid-June), make the first application of CpGV at the beginning of egg hatch or shortly thereafter. If using a degree day model to predict codling moth development then the first CpGV application should be around 250 degree days after codling moth biofix, assuming a base temperature of 50 degrees F. Make a second application after seven sunny days (two cloudy days should be counted as one sunny day). Third and fourth applications may be required under conditions of unusually high codling moth pressure, sustained egg laying or prolonged sunny weather. If you can only make two applications, it may be more effective to hold the second spray until peak egg hatch. █

Areawide Monitoring of Armyworms in Rice: An Update Luis Espino, Rice Farm Advisor, UCCE Colusa County Michelle Leinfelder-Miles, Delta Crops Resource Management Advisor, UCCE San Joaquin County

Rice PCAs are very familiar with the armyworm issue in rice. But in case you havenâ&#x20AC;&#x2122;t been following it, hereâ&#x20AC;&#x2122;s a short summary. Armyworms have always been present in rice, but have never been a key pest. In 2015, several areas experienced outbreaks, with record-breaking infestations, defoliation, and yield losses. Year 2016 was not as bad, but the worms were still causing problems. Then, in 2017, things got worse. More areas were affected. To try to control the infestations, growers used methoxyfenozide, an insect growth regulator that was granted a Section 18, and pyrethroids. The last three years have confirmed that the pyrethroids are not as effective as methoxyfenozide against armyworms. Our last armyworm damage survey showed that yield losses due to armyworms in 2017 were as high as 25%, and yield losses in fields treated with methoxyfenozide were 64% lower than yield losses from pyrethroid-treated fields. In a field trial conducted during heading, lambda-cyhalothrin reduced panicle injury by 45%, while injury reduction with methoxyfenozide was 70%. The first indication growers and PCAs have that armyworms are present in a field is defoliation. Armyworms consume very little foliage during their initial instars, and only start consuming enough

CAPCA ADVISER | JUNE 2018

foliage to be noticeable when they reach the 5th instar. At this point, control with any insecticide is going to be difficult. Ideally, insecticides should target earlier instars, when armyworms are more susceptible. However, finding these smaller worms is challenging because they are small, remain hidden during the day, and do not cause much defoliation. This is when the pheromone trap network we have established may help PCAs. Last year was the first time we tracked the flight of armyworm moths during the whole season (fig. 1). We set up pheromone traps in seven locations across the Sacramento Valley, from Richvale to the Sacramento airport, and in two locations in the San Joaquin Valley. In the Sacramento Valley, moths were detected at low numbers early in the season. Then, numbers started to increase at the beginning of June, peaked by mid-June, and then went back down by early July. After that, the number of moths trapped remained low. This pattern fit the observed dynamics of the armyworms in the field during 2017. One of the locations that I inspected closely was in Glenn County (fig. 2). This location has had severe infestations in the past. Small

INNOVATION IN PLANT NUTRITION TO IMPROVE GROWER PRACTICES

Developing solutions that bring forward the right level of tradition while changing farming practices forever Plant nutrition that is stuck in the past isn’t helpful for the future, which is why companies should be committed to finding innovative solutions to refresh the industry and develop new offerings to help growers for years to come.

Compass Minerals Plant Nutrition, which manufactures a diverse portfolio of plant nutrition products, including Wolf TraxTM DDP® Nutrients, Protassium+® sulfate of potash and ProAcquaTM, has recently opened a Kansas-based innovation center aimed at accelerating plant nutrition technologies to influence grower practices and spur crop efficiency. A diverse staff of chemists, agronomists, soil scientists, engineers, geologists and plant physiologists make up the research team focused on proprietary product development and application processes. With on-site chemistry and formulations expertise, they’re dedicated to balancing the right combination of business acumen and science to accelerate product realization and speed to market. “Our goal is to directly influence farmers’ growing practices through science,” said Dr. Ryan Bartlett, vice president innovation and product development. “In the world of agriculture R&D, the lion’s share of funding has consistently gone toward advanced breeding techniques, developing transgenics

and crop protection products. We’re working to compound the gains realized with those innovations by developing similar advances in plant nutrition.” These advances build upon an existing product line that already pushes the boundaries in improved plant nutrition. For example, the ProAcqua line of products is uniquely formulated with proprietary adjuvant blends to deliver nutrients through irrigation, foliar or fertigation. “This line is highly compatible with crop protectants and other fertilizers for one-pass efficiency in sprayer applications, which allows for the solubility and flexibility growers don’t always see,” said Bartlett. One of the most important ways our scientists learn about challenges in the field is through input from PCAs, agronomists, sales teams and customers who all contribute to next generation products. “By receiving feedback and results from our partners, we’re able to maximize their investments in the seed or jug and develop specialized nutrient solutions tailored to fit their needs,” added Bartlett. “We believe that our future is to develop next generation effective, efficient and sustainable crop nutrition products and we’re well on our way.”

OUR GOAL IS TO DIRECTLY INFLUENCE FARMERS’ GROWING PRACTICES THROUGH SCIENCE. — Dr. Ryan Bartlett, Compass Minerals Plant Nutrition, VP Innovation + Product Development

FARM ADVISORS, CONT., Areawide Monitoring of Armyworms in Rice: An Update

armyworms (1st and 2nd instars) were first detected on June 12. Severe defoliation and large armyworms (5th and 6th instars) were observed by June 21st, just nine days later. Using developmental information based on degree-days available in the scientific literature, we can estimate that egg laying started around June 5th, when trap catches were about 7 moths/day, and that the third and fourth instar larvae were in the field between June 16 and 17, when catches were about 15 moths/day. Armyworm eggs are very difficult to find in the field. An anecdote I found in a scientific paper describes that C. V. Riley, a famous nineteenth century agricultural entomologist, once offered a $20,000 reward to anyone that could find the eggs in the field. Adjusted for inflation, that reward is now equivalent to $447,000, so Iâ&#x20AC;&#x2122;m pretty certain he wasnâ&#x20AC;&#x2122;t expecting anyone to find the eggs. This illustrates the difficulty of finding eggs and using them to monitor for armyworm activity. However, we could use the number of moths trapped to estimate when 3rd or 4th instar worms are going to be in the field. This would be the time to intensify monitoring and initiate insecticide sprays. More years of trap data will be needed to develop a robust system.

Figure 1. Average number of armyworm moths caught daily using pheromone traps in rice fields during 2017. The pheromone attracts male moths.

This year, we will increase the number of sites we will monitor with pheromone traps to about 15. The idea is to give PCAs more localized data. The traps will be checked weekly, and we will summarize the numbers and post them in our armyworm website (http://rice.ucanr.edu/armyworm_traps/). We will be sending an e-mail each week once the numbers are updated. If you receive our rice newsletters through e-mail, you will receive this armyworm alert email. If you are not subscribed to our rice newsletters, then you can subscribe to the armyworm alert email on the armyworm website. Why are we seeing this big armyworm outbreak? Armyworms have been a problem in the past, but not in the magnitude we see now. There are several possible explanations, but it is difficult to be certain which is the main one. Armyworms overwinter as late instar larvae in grassy areas, probably in levees and ditches. In the past few years, our winters have been a bit milder than normal, and that may have resulted in more 40

armyworms surviving the winter, which would mean that we are starting the season with a larger than normal population. Figure 3 shows the monthly average minimum temperature registered in Durham during the last six winters. During armyworm years (2015, 2016, and 2017), average minimum temperatures during the winter leading to those years were about 4 degrees higher than minimum temperatures during non-armyworm years (2012, 2013, 2014). Minimum temperatures during 2018 are similar to the pattern of non-armyworm years, except for January. We will have to wait and see what happens. Other areas of the western US and Canada have also experienced severe armyworm outbreaks. This indicates that the problem we are experiencing is regional, and migration of moths may play a role. We will be collaborating in research exploring the origin of moths and trying to determine if our populations are permanent or depend on populations coming from other areas. More to come in the future. █

Figure 3. Average minimum monthly temperatures during winter months for nonarmyworms and armyworm years. Non-armyworm years are 2012, 2013, and 2014. Armyworm years are 2015, 2016 and 2017.

IF PLANTS WERE ROCKETS, THEN YES, THIS WOULD BE ROCKET SCIENCE.

Protassium+® sulfate of potash (0-0-50-17S) has less than 1% chloride and the lowest salt index per unit of K2O of all major potassium sources. This ensures efficient water and nutrient uptake. The result is healthier plants and higher yields — whether conventionally or organically farmed. What is scientifically better for your crop is also better for your business. So, if plants were rockets ... well then, we might just be NASA. To review field trials, plot studies and research, visit ProtassiumPlus.com.
