From the Editor Bee Where? Agriculture is a team. The grower, PCA, Applicator, Beekeeper and everyone in between has to work together to cultivate from the soil what we eat on our tables each day. In California, we need bees for a variety of crops, but, most notably, almond bloom. Nearly 1.5 million hives arrive from out of state to help accomplish almond bloom along with the 500,000 native hives that are in-state year around. But numbers as low as 5% of the bee hives in California during almond bloom are registered with a local Ag Commissioner’s office. Although there are clear regulations in place, this time of year becomes stressful with extra work to identify hives and track down contact information to notify beekeepers of applications. The regulations set up under the Food and Ag Code were meant to facilitate communication, but with low compliance for registration by beekeepers, especially those coming from out of state, agriculture has continued to miss the opportunity for open communication between stakeholders during bloom. After traveling to different parts of the state during bloom last year, I started to wonder how the team of Agriculture could leverage technology and professionalism to ensure that the regulations already in place can be utilized during bloom for the success of all stakeholders. In working with Ag Commissioners, CDPR and CDFA over the last six months, we are close to a solution. Bee Where is poised to launch for bloom in 2019 as a new GIS mapping layer integrated into Cal Ag Permits (and subsequently any rec writing system linked in). This interactive map will track registered bee hive locations in real time and allow applicators to easily access all registered bee hives within a mile of an application during bloom. Replacing cork boards and push pins in some counties, this technology layer will bring a whole new level of efficiency to the entire process. Registration of the bees remains the key piece to this puzzle. Along with the Ag Commissioners Association (CACASA) running bill AB 2468 to drive registration compliance and CDFA allocating 1.5 millon/year towards bee registration and enforcement, CAPCA is working with key commodity groups and stakeholders to integrate a registration requirement into grower-beekeeper contracts. As CAPCA pivoted our Government Relations priorities and outreach last year, this has been a proactive project for us to lead and develop good will for our membership and association’s goals. We are looking forward to rolling out this project to the CAPCA membership this fall! █ Ruthann Anderson, Editor ruthann@capca.com

LEADERSHIP

Next Generation Education By Rick Wescott, CAPCA Chairman

I had the opportunity in January to attend the State Agriculture Ambassador Conference at Cal Poly, San Luis Obispo as one of their presenters for the program. The Ag Ambassador program is a college-based program of college students promoting agriculture. The conference had participation of colleges from Northern CA to Southern CA, with about 100 students in attendance. I was one of many industry representatives that were in attendance to educate the students about the variety of jobs available to them upon graduation. My presentation revolved around CAPCA and the job of being a PCA, and how CAPCA advocates for PCAs in California. I talked about the history of CAPCA and how following the activities in California government with the legislature and CDPR is one of our biggest priorities. I discussed some of the major issues we deal with, such as water availability and continued regulations regarding pesticides. I discussed how safe pesticides are today, as compared to what we had available to us years ago, and how growers are under constant attack on all aspects of how they farm and the environment. The biggest eye opener for me was what I learned from the students themselves. Out of the 100 in attendance, there were only eight who were interested in becoming a PCA when they graduate. A majority of the students had no agricultural background, but decided they wanted to pursue a degree in Ag. The other thing that I discovered is how little they knew about what is going on in agriculture today, like water issues and the constant environmental community pressures on farming practices. They had no idea how much time, research, and money it takes to get just one pesticide registered and the safety margin that is built into each and every one of them. They were so surprised that any of these issues existed but were thankful for the insight that I provided. After being a part of this program and learning what college students are learning, or in this case not learning, I have come to realize that our jobs as PCAs are more than just what we do day after day. We must always take the opportunity to educate others about our profession, the truths of Agriculture and the safety of their food supply. We should all be proud of the contributions we make to provide food for the entire world and never be afraid to talk about it!

CAPCA ADVISER | APRIL 2018

The discussion of the importance of the PCA profession is one area that CAPCA is working on ramping up this year through the Pathway to PCA program. State office staff will be increasing their outreach with more visits to campuses in the state, as well as other functions where students are present, thereby expanding the efforts of the Pathway program to have a greater presence and increase CAPCAâ&#x20AC;&#x2122;s messaging. We will be putting our best foot forward and doing our very best to engage students who are currently making their career choices to become the next generation of PCAs. In this way, CAPCA will continue to satisfy its mission to facilitate the success of the PCA profession. â&#x2013;&#x2C6;

Ensure season-long control of pre- and post-emergent weeds WEEDS REDUCE TREE HEALTH AND CROP QUALITY. Weeds compete with trees and vines for nutrients, water and light and can impact yield and hinder harvesting practices. Weeds can even compete with target plants for uptake of insecticides and other chemicals, making the crop more susceptible to insects and disease.

Key weeds present in orchards and vineyards have been found to be resistant to glyphosate. A best practice to slow down weed resistance to herbicides includes using multiple effective modes of action in your pre- and post-emergent herbicide sprays.

WEEDS RESISTANT TO GLYPHOSATE

While cultural and mechanical practices can provide some help in managing weed pressures, most growers utilize herbicides to deal with major threats. Whether or not resistant weeds are currently present, having an integrated approach to weed control can mean the difference to bottom lines.

Alion® and Rely® 280 weed program from Bayer are complementary pre- and post-emergent herbicides for tree nuts, grapes and citrus that effectively eliminate tough grass and broadleaf weeds with long-lasting residual control and excellent crop safety. Together, Alion and Rely offer versatile application approaches to ensure you start and stay weed-free.

LEADERSHIP

2018 Advocacy by CAPCA Staff In January, CAPCA members from the Government Relations and Public Relations Committees participated in a training event to equip them in effectively engaging local communities, media, public officials and lawmakers. Featured speakers included California Farm Bureau past president Paul Wenger, Riverside Agricultural Commissioner & incoming CACASA President Ruben Arroyo, and George Soares of Kahn, Soares, Conway, CAPCA’s lobbying firm. Mr. Arroyo provided an overview of CEQA Equivalency and the authority PCAs are licensed under. He gave insight into the Agricultural Commissioners system in California, and the different regulatory bodies involved at local levels. A valuable part of his training also included Crisis Management strategies, preparation and practice in talking with media in response to a crisis. He emphasized building relationships through listening before the crisis, and being prepared with the information you want to talk about when the time comes. CA Farm Bureau’s former president Paul Wenger shared with CAPCA leaders the importance of thinking of agriculture as a team, stressing the strategic value of working together and that advocacy is really work, in small ways over time. Success will come from individuals in agriculture, like PCAs, being able to reframe how decision makers and the public perceive issues - “Your voice counts more than hired ones sometimes."

CAPCA ADVISER | APRIL 2018

These ideas were also advocated by George Soares from CAPCA’s lobbying firm. Mr. Soares attended both the January Committee training and the February Presidents’ Summit to share his knowledge and experience with CAPCA Chapter Presidents and representatives. He provided insight into the workings of California’s government and ways that CAPCA PCAs would be successful in giving voice to ‘team ag’: practicing your communication, being disciplined in your storytelling and not speaking in ‘ag code’ to those outside the industry. With years of valuable experience between them, all three presenters shared many significant anecdotes that conveyed how valuable the voices of PCAs and those doing the work are to the future of agriculture. They each shared important insights that will be incredibly helpful to members in upcoming advocacy efforts. CAPCA thanks them for their time and willingness to share with our members. CAPCA advocacy efforts are primarily coordinated through local Chapters or State Committees.

CAPCA ED

Leadership Summit Engages Chapter Presidents CAPCA Ed Representative Ariana McCray On Wednesday, February 7, the CAPCA Chapter Presidents came together for the Annual Presidents’ Summit. The presidents discussed their chapters' goals, accomplishments, chapter purposes, and struggles. A common struggle that most, if not all, chapters are having is recruiting new members to participate in chapter activities and joining their local board.

CAPCA REPRESENTATIVE

Attending this Summit has given me, as CAPCA representative, a better understanding of where I can actively assist the chapters to aid in their success, whether it is assisting with a campus visit or providing supplies for successful outreach or events. Also in attendance was the Liberty Ranch FFA Chapter Parli Pro National Champions with their advisors, Melissa Porter and Brian Dodson. The FFA members and advisers presented the chapter presidents with an overview of Robert’s Rules to properly run a meeting. Thank you to Liberty Ranch FFA and Katie Otto for their enthusiastic participation. As your CAPCA Representative, I would like to thank those chapter presidents who attended and provided us with their insight. I look forward to working closer with your chapters! █

AG COMMISSIONER PROFILE

Rick Gurrola: Leveraging Technology and Building Relationships for Success in Tehama County By CAPCA Staff Rick Gurrola has served as the Tehama County Agricultural Commissioner, Sealer of Weights & Measures, and Director of Animal Services since 2004. He began his career in the industry over thirty years ago with the Tehama Department of Agriculture, after attending California State University, Chico and obtaining a Bachelor of Science Degree in Agriculture Business in 1981. Describing his role as the Ag Commissioner in Tehama County, Mr. Gurrola summarized it as protecting the public and environment through education and uniform enforcement at the local level of the California Food and Agricultural Code, and the California Code of Regulations. “I receive routine questions and comments about regulatory burdens. I empathize with the ranchers and farmers, who are the ultimate land stewards, concerning the myriad of laws, regulations and local ordinances they must contend with to provide consumers with a wholesome, safe and affordable food supply. I, and my department, strive to work with the local agriculture industry to ensure compliance of pesticide related laws and regulations through outreach and education.” In a recent survey of Tehama County Business Owners, the Agricultural Commissioner’s office was positively described as “very helpful” and “customer service orientated.” This focus on communication and collaboration, along with technology, is foundational to some of Mr. Gurrola’s career highlights as an agricultural commissioner. “Recent IT projects have improved efficiencies for industry and regulators. I’ve been actively involved in IT projects as a committee member with the California Agricultural Commissioners and Sealers Association (CACASA) beginning in 2010 with the CalAgPermit program. Through cooperative efforts, CACASA and the California Department of Pesticide Regulation (CDPR) sponsored CalAgPermits, a statewide permitting and pesticide use reporting information management system. The web-based system was deployed in all California counties at the end of 2011.” He explains that CalAgPermits is used by officials in all offices of county agricultural commissioners to create and modify permits and operator identifications, maintain licensed pest control business contact information, and perform data analysis and queries on permit and pesticide use data. The system includes features for businesses and individuals who apply pesticides in California to complete and submit required Pesticide Use Reports (PURs), including Notices of Intent (NOI) to apply restricted materials. NOI and PURs can be submitted using online forms, or 16

CAPCA ADVISER | APRIL 2018

transmitted electronically using a variety of commercial software products which have been interfaced with CalAgPermits. In January 2015, CACASA and CDPR launched development of the California Pesticide Enforcement Activities Tracking System (CalPEATS) and successfully began deployment in October 2016. CalPEATS is a standardized, modern, and coordinated information technology platform that integrates all county and CDPR pesticide enforcement records and activities throughout California and makes them readily available for assessment. Providing CDPR and county staff access to the same system will increase productivity, enhance the speed and accuracy of communications, and eliminate significant volumes of redundant data entry. Effective January 1, 2018, CDPR adopted new rules to further protect young students from pesticide exposure by regulating the use of agricultural pesticides near schools and licensed daycare facilities. The regulation is designed to encourage greater communication between growers and these entities. Building upon recent successful programs, CDPR and CACASA are continuing effective collaboration via utilizing CalAgPermits as a foundation for CalSchoolNotify.org. This new system will effectively allow for regulatory compliance with modern technology. This new regulation is cited by Mr. Gurrola as a significant concern to local farmers: Many pesticide applications are now prohibited within a quarter 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 includes all applications by aircraft, sprinklers, air-blast sprayers, and all fumigant applications. In addition, most dust and powder pesticide applications, such as sulfur, will also be prohibited during this time.

The regulation also increases the workload to all California County Agricultural Commissioner’s offices. His department has devoted hundreds of hours to this new program, from assisting with the development and implementation of the statewide program and accurately mapping of these facilities and agriculture properties within Tehama County, to training and outreach activities. The new notification program, CalSchoolNotify.org, will allow for these notifications to be prepared by farmers (and agriculture commissioner staff), and then submitted electronically to all affected daycare facilities and schools in California. Among other agricultural challenges noted in Tehama County are Walnut Blight, Navel Orangeworm and Walnut Husk Fly. Since walnuts are the primary crop in the county (accounting for 31% of the overall total county agriculture crop value), these diseases/ pests pose a serious economic concern. Almond growers routinely contend with Brown Rot and Navel Orangeworm also. In addressing these concerns and challenges, Mr. Gurrola plans to continue to build relationships and look to future technology: “I believe we effectively communicate with CAPCA and local PCAs now. Attendance from our respective organizations at local and statewide meetings and conferences of mutual interests helps to reinforce both communication and relationships. Strengthening our relationships through collaboration on current and future issues should serve us all well.” Another current endeavor he highlights is electronic mapping for all apiary locations through GIS mapping programs developed for the CalSchoolNotify.org program. This will further improve his office’s ability to work with PCAs, growers and beekeepers concerning pesticide applications. █

New Quarantine Regulations for Asian Citrus Psyllid and Huanglongbing

by Alyssa Houtby, California Citrus Mutual The devastating citrus plant disease Huanglongbing (HLB) continues to be found at an alarming rate in back yard trees in Los Angeles and Orange Counties. Recently the disease was detected in Riverside County, within close proximity to commercial citrus groves and nurseries and UC Riverside – adding a new level of urgency in the fight to save California citrus. As the disease threatens to invade commercial citrus orchards, it is critical that growers, packers, transporters, PCAs, and other industry partners continue working together to protect this vital industry. At the request of citrus growers and to more effectively protect California citrus from HLB, the California Department of Food and Agriculture implemented a new regional Asian Citrus Psyllid (ACP) quarantine for movement of bulk citrus and nursery stock. While the compliance process relies on growers, packers and transporters, PCAs should be aware of these new quarantines and resulting mitigation implications. Ensure loads are ACP-Free The ACP-free compliance standards for bulk citrus movement remain the same when moving citrus between regional quarantine zones, however, the quarantine zone boundaries have changed. One of the following mitigation options must be completed in order to move a bulk shipment to any zone outside of the zone in which the fruit was grown: • Field Cleaned Option: Fruit must be field cleaned and be practically free from all stems and leaves.

CAPCA ADVISER | APRIL 2018

• Treatment Option: Grove or fruit must be treated with a CDFA agreed upon pre-harvest or post-harvest product effective against psyllids within 14 days of harvest. A list of products and use rates recommended by University of California, Integrated Pest Management Program (UC IPM), and agreed upon by CDFA is available at http://phpps.cdfa.ca.gov/PE/InteriorExclusion/pdf/ acpgrowerinformation.pdf. Every load of citrus should be accompanied by an ACP-Free Declaration Form indicating which mitigation option was used. Tarping Requirement All fruit must be transported to the packer or processor in a fully enclosed vehicle or completely covered by a solid or mesh tarp to prevent exposure to ACP or the loss of any fruit or plant material. This requirement is being actively enforced by CDFA, county agriculture departments and local law enforcement. Vehicles with improper tarping or enclosure may be stopped and cited for regulation violation. Resources are available Information about ACP and HLB and the new quarantine regions is available on the Citrus Pest and Disease Prevention Program website CitrusInsider.org. Go to Citrusinsider.org for answers to questions such as: Are there new ACP-free compliance standards for bulk citrus movement when moving citrus between these new regional quarantine zones? What are the quarantine boundaries? What do I need to do to move citrus out of one quarantine and into another? █

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.

Biochemicals Versus Biologicals: How They Can Work Together Michael Larose, BioSafe Systems Whether we buy into the hype or not, sustainability and organics are two of the hottest buzz words in vegetable and fruit production in every region of the country and even more prevalent in Europe and Asia. Growers, packers, processors and ultimately retailers have all experienced the dramatic shift in consumer preference for sustainable practices in agricultural production. Conventional or organic, growers are facing relentless pressure from buyers across the globe to implement and then prove that they are incorporating sustainable practices in their production process. Not only has this trend driven changes in the agriculture market here in the United States, but it has dramatically impacted growers’ ability to develop and service overseas markets where chemical residue limitations and sustainability requirements has driven an even larger emphasis on developing effective, economical and sustainable practices that produce a quality crop. Large retailers are leveraging their purchasing power by incorporating sustainability goals and objectives that in the end are driven by the retail consumers. This rapid shift in production practices has spawned an enormous growth in Biopesticides that allows growers to produce a crop, whether they’re organic or conventional, that at the minimum reduces the amount of synthetic chemistries used in the production process. And here lies the challenge: the consumer demand for sustainability, which has influenced growers to adopt IPM (Integrated Pest Management) practices and incorporate biopesticide solutions, has outpaced the ability of our valued researchers and influencers to educate the agriculture industry in how to utilize these solutions effectively and, most importantly, economically. With the sustainability discussion out of the way, there’s another critical component that makes incorporating biopesticide products into crop protection programs highly attractive: RESISTANCE MANAGEMENT! It’s no secret that over-dependence on synthetic chemistries and the decades of reliance on such chemistries has led to an exponential growth in resistant pathogens, pests and weeds; the agricultural industry has strived to “slowdown” the resistance challenge, one by creating the FRAC/IRAC coding system providing growers with a guide for responsible resistance management and two by taking single active ingredients and formulating products that provide multiple modes-of-action. This is strictly a quick-fix to a never-ending challenge, nature and biology will inevitably out-whit our synthetically produced band-aids; however, this equation changes in our favor with the appropriate use of Biopesticides as a supplemental tool in at least managing pathogens and pests. It’s nature versus nature!

CAPCA ADVISER | APRIL 2018

Biopesticides are becoming and will continue to become an increasingly important tool in our ever-shrinking tool-box for both conventional and organic growers alike, providing a variety of implementation opportunities into growers’ IPM programs. Over the last 10 years researchers and manufacturers of biopesticide products have been working feverishly to provide real-world best practices and supporting information on how to effectively and economically utilize these innovative, new generation of crop protection tools. Biopesticides are generally put into 3 primary categories: 1) Biochemicals – naturally occurring substances that control pests by non-toxic mechanisms. Examples of biochemical tools include: a. Broad-Spectrum Contact Bactericides/Fungicides (Peracetic Acid-PAA, Potassium Bicarbonate, Copper, Sulfur and/or Lime-Sulfur) b. Plant Extracts (Neem Oil/Azadirachtin, Giant Knotweed, Pyrethrum Plant) c. Insect Sex Pheromones (Monitoring, Trapping, and Mating disruption) 2) Microbial pesticides – consist of a microorganism as the primary active ingredient, with many microbial pesticides targeting specific pests and thus less broad-spectrum. a. Bacillus spp. b. Pseudomonas spp. c. Trichoderma spp. d. Gliocladium catenulatum spp. 3) Plant-Incorporated-Protectants (PIPs) – pesticidal substances that plants produce from genetic material that has been added to the plant a. Bt gene from Bacillus thuringensis (i.e. Bt cotton & Bt corn) Understanding the differences between these various products all under the umbrella of “Biopesticides” is a critical first-step in knowing what each product can address and how it will improve your Crop Protection program.

COMMUNICATIONS, CONT., Biochemicals Versus Biologicals: How They Can Work Together

(BPIA), with their mission and goal focused solely on providing education and resources to CCAs/PCAs, growers, and consumers to help lift the vail on these new tools not only in agriculture, but also horticulture, landscape/nursery, pest control, and animal health industries. Two categories in the biopesticide portfolio, biochemicals and biologicals, provide unique synergies in crop protection programs. Biochemicals are traditionally broad-spectrum non-target specific chemistries that are ideal for eradicating established fungal pathogens and their spores as well as established bacterial diseases and their inoculum, which is critical when trying to stop the rapid spread through a field or orchard. The unique properties of biochemicals make them a critical partner when growers are also utilizing biological tools to aid in preventive control of foliar and soil pathogens. Biochemicals, such as Peracetic Acid (PAA), are highly effective at “cleaning” the foliar surface and treated area; providing rapid knock-down of pathogens and their dormant spores or inoculum. Biochemicals must be applied prior to the use of a biological product, allowing the biochemical to reduce the levels of fungal spores and/or bacterial inoculum on the treated surface. Most biochemicals provide a rapid broad-spectrum knock-down on a foliar surface or in the soil profile, converting into inert properties within 24 hours after application allowing for biological tools to be quickly applied following the application of the biochemical. It’s these unique principles that provide the synergistic properties between the biochemicals and biologicals: • The biochemical provides curative properties of established pathogens on the foliar surface OR when used in soil applications it helps reduce the populations of soil-borne pathogens and pests • The biological product can be applied after a short interval ensuring growers can confidently apply a biological product allowing the components of the biological fungicide to rapidly populate on the treated surface without having to overcome high populations of dormant or active fungal or bacterial pathogens.

CAPCA ADVISER | APRIL 2018

Biochemicals play a major role in reducing the moderate to high populations of foliar and soil pathogens that are present in the field, encouraging a clean and attractive environment for beneficial organisms efficiently populate in the treated area. With many of the biological products utilizing beneficial strains where the primary mode of action is exclusion, meaning these beneficial organisms populate at a rapid rate and inhibit plant pathogens from re-inoculating the treated surface, without having to overcome or compete against existing high populations of both plant pathogens or other yeasts, molds or fungus naturally present in the environment. An area that is in desperate need for new innovative treatment tools, this unique approach of utilizing biochemicals with biologicals has shown immense success in soil treatment studies, where a soil sterilant such as Peracetic Acid is chemigated through drip irrigation systems to eliminate soil pathogens such as pythium, phytophthora, and fusarium prior to or just at planting. Peracetic Acid breaks down within 24-hours into inert components of oxygen and water, allowing growers to quickly inject beneficial organisms back into their soil profile thus allowing them to rapidly colonize along the rhizosphere and root structure. Although producers have hesitated in the past in adopting biopesticide products into their operations, the agriculture industry is rapidly introducing new educational tools, best practices, and trade meetings to meet the increasingly vocal demand by consumers for sustainable production practices. In addition, incorporating these new and innovative crop protection tools collectively help lengthen the effectiveness of our traditional chemistries through reduced applications and longer chemical rotation cycles. Couple this with stringent residue limits set forth by European and Asian markets and the increasingly attractive profits to be earned in exporting crops abroad, adopting biopesticides into traditional production practices will continue to gain momentum and the whole industry will benefit for years to come! █

BOTRYOSPHAERIA

Taking Control of Botryosphaeria in California Walnut Orchards

The disease has a multi-season impact on orchards. Bot infects and damages the current year’s fruit, and also the fruit wood that will produce fruit the following year. “In some mature walnut orchards, we’ve seen yield declines of 25 percent or more in the first year, with additional declines the second year and potentially devastating impacts to the health of trees in the orchard,” said Chuck Gullord, a technical sales representative for Bayer. Botryosphaeria spores germinate and enter the tree through existing wounds or scars, such as those from pruning, leaf and fruit drop or bud scars. Research conducted by the University of California in 2014 found that untreated wounds can be susceptible to infection from Bot fungi for extended periods. For example, pruning wounds in medium to large branches can be infected for at least four months after the pruning cut is made.

Chemical control programs are highly effective in controlling Bot fungi as well as scale and other damaging insects that allow disease to spread.

“Walnut trees with scale infestations are

60 to 70 percent more

prone to Bot infection.”

While walnut scale damage has historically not been considered a significant economic threat to walnut production, the lesions on trunks and old branches caused by scale are a key entry point for Bot infection. Walnut trees with scale infestations are 60 to 70

Bayer provides several solutions for walnut growers. Luna Sensation® and Luna Experience® fungicides are highly effective in controlling Bot fungi, and Movento® insecticide provides effective control of scale and other major insects and mite pests.

Botryosphaeria are a group of fungal pathogens that have been well-known for decades in the California pistachio industry, with initial discovery in 1984 and significant production loss to the disease in the late 1990s. However, Bot pathogens have emerged as a growing challenge to walnut tree health and yields in California in the past three to four years. In walnuts, Bot can easily spread from tree to tree by wind or water, and spores germinate with a quarter-inch of rain or as little as 90 minutes of exposure to water.

Cell Wall Calcium: A Good Tool for Diagnosing Alterations in Fruit Quality Kenny Lam, Agronomy Director, AGQ Labs USA

It is well known that post-harvest is a key period with a direct influence on the quality and appearance with which fruits and vegetables reach their point of sale. Even if we have done a superb job in the field, if the product does not successfully endure the period between harvest and sale, we will have failed. Several factors have a bearing in this process. One factor with a major role is tissue calcium content. Calciumâ&#x20AC;&#x2122;s structural function is directly related to plant tissue stability and thus to the productâ&#x20AC;&#x2122;s post-harvest behavior (rotting, brown spots, loss of consistency, etc.), as well as its probability of being affected by pre-harvest damage (creasing in citrus fruit, cracking in stone fruits, bitter pit in apples, etc.). In addition to having a structural function (for cell wall bound calcium in the form of calcium pectates), calcium is involved in other functions in plant cells. It is thus also found in other plant parts, as soluble calcium in the apoplast and symplast (in the form of nitrates, chlorides and amino acids), insoluble calcium in form of precipitates in the vacuoles (mainly in the form of phosphates,

carbonates and oxalates) and residual calcium in highly insoluble forms (mainly). Historically, it has been difficult to correlate structural damage in fruits (pre- or post-harvest) to total calcium content of the tissue. Now, a number of scientific studies have demonstrated a direct relationship between the cell wall calcium fraction in the form of calcium pectates, on the one hand, and structural behavior of the tissue on the other. This makes wall cell calcium a powerful, innovative tool for diagnosing alterations in the quality of fruits and vegetables. Up until now, the majority of the tests conducted have estimated cell wall calcium indirectly, as the difference between total calcium and soluble calcium. Such a procedure is inexact; it overestimates the bound fraction by adding the insoluble and residual fractions, which are sometimes greater than the bound fraction. The evolution of calcium fractions throughout the ripening period of the fruits (e.g. tomatoes) has been studied, comparing fruits that do and do not experience specific alterations (e.g. bitter pit in apples or cracking in peaches). As a result of these tests, the concussion is that that cell wall calcium is a diagnostic tool for evaluating quality parameters related to the appearance and market life of the product. And in certain matrices, total calcium, with quantification limits adapted to the fruit, is also a very reliable marker for assessing a number of concrete alterations. â&#x2013;&#x2C6;

State Water Resources Control Board Adopts Agricultural Order for Eastern San Joaquin River Watershed by Johnny Gonzales, CalEPA, State Water Resources Control Board

On February 7, 2018, the State Water Resources Control Board (State Water Board) adopted a Waste Discharge Requirement Order (WDR) revising agricultural requirements for the Eastern San Joaquin River Watershed (ESJ) that include requirements to reduce nitrate contamination of groundwater and surface water. The State Water Board recognizes that addressing water quality impacts associated with agriculture poses a complex challenge. The same activities that are relied upon in producing an essential and reliable food supply, such as pesticides used to control pests, nitrogen to fertilize crops, and irrigation to water crops, also may have environmental consequences. Further, many of the impacts from agriculture are due to historic rather than existing practices. The ESJ WDR seeks to take advantage of technical advances that allow for more precise use of agricultural inputs to minimize potential overuse of these inputs, which should make California agriculture more sustainable. Following extensive public comment and expert input, the ESJ WDR is aimed at protecting communities that rely on groundwater for their drinking water. Nitrate contamination of drinking water is a widespread problem that poses serious public health risks. Nitrates can also have adverse impacts on surface water and aquatic ecosystems. The ESJ WDR also directs protections for surface water and groundwater quality from other chemicals, including fertilizers, herbicides, and pesticides that many be found in agricultural discharges. The ESJ WDR revises waste discharge requirements for the Eastern San Joaquin River Watershed issued by the Central Valley Regional Water Quality Control Board in 2012. The watershed comprises an area of about one million acres of irrigated agriculture in the eastern San Joaquin Valley. The ESJ WDR also establishes a model for all regional water boards to follow in their subsequent orders to reduce pollutants from irrigated agriculture around the State. The ESJ WDR sets precedence statewide and directs the regional water boards to revise their respective agricultural orders to incorporate testing of drinking water quality for on-farm wells and address the long-term goal of improving groundwater and surface water quality through 34

monitoring and controlling agricultural practices, specifically nitrogen management. To improve monitoring of nitrogen impacts, the ESJ WDR also sets precedence statewide directing the regional water boards to require the reporting of nitrogen application to crops from fertilizers, organic soil amendments, and in irrigation water, as well as data on nitrogen removed when crops are harvested and taken from the fields. For the Eastern San Joaquin River Watershed, starting in 2021, the order extends some of the same nitrogen reporting requirements previously only required for areas considered high vulnerability for impacts to groundwater to all agricultural areas, with some exceptions. The ESJ WDR makes other changes to the reporting requirements, including the inclusion of new reporting on potential groundwater loading from nitrogen fertilizer use and targets for groundwater quality. The WDR also directs the regional water boards to require that growers report on the management practices they are implementing to control pollutants in addition to the use of nitrogen. Reporting the amount of nitrogen applied and removed, along with management practices, allows analysis by the regional water boards of whether regional regulatory programs are effective in protecting water quality to assure that progress is made. The State Water Board also required review of how the different regional board approaches to the irrigated lands programs are doing within three years of the date of the order. To protect people presently using on-farm drinking water wells, starting in 2019, the ESJ WDR requires that growers monitor for nitrate levels in on-farm drinking water supply wells and notify the users of those wells if water is found to be above drinking water standards. This provision will come into effect if there are no statewide programs requiring the testing of domestic wells by January 1, 2019. Many of the changes the ESJ WDR incorporates are recommendations from the following: a nitrogen tracking task force and an agricultural expert panel convened as a result of legislation

CCA Update, CONT., State Water Resources Control Board Adopts Agricultural Order for Eastern San Joaquin River Watershed

[Chapter 1 of the Second Extraordinary Session of 2008 (SBX2 1, Perata)]; a Board-adopted Report to the Legislature that made recommendation on how to address nitrates in drinking water, and the State Water Board’s previous WDR from 2013 regarding a petition of the Central Coast Regional Water Board’s agricultural regulatory program. CAPCA-CCA representatives brought up a concern regarding potential liability from any failure in the execution of an Irrigation and Nitrogen Management Plan. In expanding the certification requirement, the State Water Board acknowledged sensitivity to the concerns expressed by professionals certifying the INMP regarding potential liability for groundwater nitrate impacts, as well as the scope of their professional insurance coverage. With regard to liability under the Water Code, the State Water Board notes that consultants to dischargers are generally not considered to be dischargers of waste and therefore not liable for violations of the dischargers’ waste discharge requirements. Program Background California’s agricultural industry produces more than 400 commodities at more than 75,000 farms and ranches. A significant part of the state’s economy, agriculture is valuable for the food and fiber it produces for people and animals. Agriculture is especially significant within the Central Valley, where it represents more than seven million acres of irrigated lands, of which approximately one million are in the Eastern San Joaquin Watershed. At the same time, the water quality impacts from agriculture include toxicity in surface water that threatens aquatic species, and salts, nitrates, and other chemicals in groundwater that adversely affect the quality of groundwater for irrigation, municipal, and other uses. An especially significant public health issue, particularly for pregnant women and infants, is drinking water from wells with high levels of nitrates.

CAPCA ADVISER | APRIL 2018

The State Water Board and regional water boards have been working with growers and other interested parties to address the environmental and public health impacts from agriculture, while at the same time ensuring the continued viability of agriculture in California. The Central Valley Water Board began regulating agricultural discharges to surface water in 1982 with limited conditions focused on preventing toxicity or excess sediment discharge. In 2003, in response to revisions to legal requirements, the 1982 permit was re-examined and the regulatory strategy was modified to include surface water monitoring to determine if and where irrigated lands might be contributing to water quality problems. The 2003 changes also allowed growers to form discharger coalitions, with a third-party representative responsible for grower outreach and education and implementation of program requirements. In 2006, the Central Valley Water Board modified the permit again to require management plans where water quality problems had been identified. In 2011, the Board certified an environmental impact report for a long-term irrigated lands program that would address both surface water and groundwater quality protection and proceeded to issue several watershed- or commodity-specific permits. The Eastern San Joaquin Agricultural General Waste Discharge Requirements were the first of the long-term irrigated lands program permits issued and have been in effect since 2012.

Special to the Adviser

Importance of Potassium in Nut Trees & Grapes Armando Gutierrez, Sales Account Manager, AgroLiquid Spring is here! It brings a sense of rejuvenation, renewal, resurrection and regrowth. Spring also brings a new growing season, and we, as growers, PCAs and suppliers, will do our best to overcome every challenge that comes our way this growing season. Blooming on nut trees in January in the Chico area and February in the Central California area gave us the first indication that we were going to have an early start to this growing season. Likewise, the grapevines are looking vigorous this spring and in the process of producing high quality grapes for the tasting pleasure of millions of people. With the growing season well underway, there is no time to waste. We need to continue considering the benefits of applying K2O to trees and plants to provide for their general health. Nut Trees Nut trees use more potassium (K) than any other nutrient except nitrogen. Their highest usage of K is typically during the months of May, June, and July. It is vital to evaluate the availability of K in our soils each year to make sure that we provide the quantity required to grow a healthy crop. The application of K2O also promotes healthy root growth, which is key for nutrient uptake. K regulates the opening and closing of stomata, it helps increase the size and quality of the fruit or kernel, and helps protects the trees from weather conditions such as heat, drought, or winter stress. Potassium is a highly mobile nutrient in the plant, and deficiencies will be visible first on the older leaves. The problem is that when leaves have visible symptoms of a potassium shortage, the tree has already been lacking the nutrient for some time, and it will take a long time to correct the deficiency in the tree. Therefore, I recommend that in addition to annual soil analysis reports, growers take leaf tissue samples, based on UC Davis guidelines. Tissue tests in mid-July will show the nutrient status of the trees mid-season, 38

CAPCA ADVISER | APRIL 2018

when the concentrations are more stable. The results of these leaf samples help guide adjustments to the original nutrient application recommendation. Based on calculations from the University of California Cooperative Extension, we know that every year around 92 lbs. of K2O are removed from the almond orchard for every 1,000 lbs. of kernel harvested. We need to replenish this same amount removed at harvest every year. We should also add to our calculations both the soil analysis report and the leaf tissue reports as reference to determine the actual quantity of K2O needed to prevent future deficiencies. This formula for determining an application rate gives growers the best chance to maximize their fertilizer return on investment next growing season. Grapes Grapevines are also great users of potassium. Potassium affects the health and vitality of vines in much the same way as is nut trees, but it also greatly affects the Brix (sugars), fruit size, weight and quality in the grapes, as well as promotes better cell structure. Wine grapes remove about 4.94 lbs of potassium per ton of fruit harvested. I often suggest applying K2O to the wine grapes at bud break and 6â&#x20AC;? shoots. However, growers may also decide to spoon feed their grapes throughout the growing season. I prefer fertilizers that allow the flexibility to apply them using any method that we consider best for our field operations. Unlike nut trees and other fruit trees where we use leaf tissue samples to monitor nutrient levels, researchers recommend using petiole tissues from grapevines during full bloom. Taking the petiole sample at full bloom assures the tissue will be at the same

physiological age, year after year, regardless of seasonal differences. As with soil samples, petioles should be collected from a single block, and areas of distinctly different soil, vine type or appearance, or other condition, should be sampled separately. There are many factors that can affect vineyard nutrient usage and need. Several may seem intuitive, for instance, heavy crop loads can dramatically lower petiole K levels during fruit ripening. Looking specifically at potassium levels, we know they can vary as much as 30-50% from year to year in the same vineyard. Potassium content is strongly affected by variety, rootstock, and irrigation practices, which accounts for much of this fluctuation.1 Another factor affecting California is that there are many areas where the soil analysis reports show sufficient levels of K, however, due to high clay or silt content, these areas have a high potassium fixing capacity. In fact, many soils in the San Joaquin Valley can tie up 50% or more of added K2O. 2 In those K-fixing soils, we need to use K2O foliar applications to supplement the soil application— continually spoon-feeding nut trees and vineyards with available K throughout the growing season. Regardless of the crop grown, providing adequate amounts of nutrition is vital to healthy plants and superior yield. As the costs versus benefits of K2O applications to trees and plants is evaluated on your operation, consider contacting a crop nutrition expert to review your soil analysis and tissue samples. These agronomists are a valuable resource to help assess the crop nutrition needs on your operation. █

Managing Arthropod Pests in Zucchini with Chemical, Botanical, and Microbial Pesticides Surendra K. Dara1, Sumanth S. R. Dara, Suchitra S. Dara, and Ed Lewis2 Strawberry and Vegetable Crops Advisor, University of California Cooperative Extension; 2 Professor and Head, Entomology, Plant Pathology & Nematology, University of Idaho 1

Zucchini crop is susceptible to a variety of arthropod pests that cause varying degrees and types of damage. For example, large populations of aphids and whiteflies cause leaf discoloration, stunted plant growth, and secrete large amounts of honeydew that leads to sooty mold development. Some may also transmit viral diseases. Thrips damage can cause bronzing of leaves, stunting of foliage, and scarring and deformation of zucchini fruit. A study was conducted in the summer of 2017 to evaluate the efficacy of various chemical, botanical, and microbial pesticides against arthropod pests. Zucchini plants initially had a high aphid (unidentified) infestation, but populations gradually declined due to natural control by lady beetle activity. However, heavy silverleaf/ sweetpotato whitefly (Bemisia tabaci) infestations developed by the time the study was initiated. Other pests that were present during the study period were aphids, the western flower thrips (Frankliniella occidentalis), and the pacific spider mite (Tetranychus pacificus). Methodology Zucchini cultivar Black Beauty was planted on July 5 2017 with a mechanical transplanter and standard agronomic practices were followed for irrigation and fertilization except that no pesticides were applied. Treatments included i) untreated control, ii) flupyradifurone at 14 fl oz/ac, iii) sulfoxaflor at 2.5 fl oz/ac, iv) heat-killed bacterium, Burkholderia rinojensis strain A396 at 4 qrt/ ac, v) entomopathogenic fungus, Isaria fumosorosea Apopka strain 97 at 2 lb/ac, vi) I1800AA (undisclosed botanical extract) at 10.3 fl oz/ac, vii) I1800A at 12.7 fl oz, viii) I1800A at 17.1 fl oz, ix) I1800A at 20.5 fl oz, and x) VST-00634LC (based on a peptide in spider venom) at 25% vol/vol. Each treatment had two 38” wide and 300’ long 40

rows of zucchini replicated four times. Treatments were arranged in a randomized complete block design. A spray volume of 50 gpa was used for all treatments except for VST-00634LC, which had 25 gpa. Treatments were applied on 28 August and 4 September 2017 using a tractor-mounted sprayer with three Teejet 8003vs flat spry nozzles that covered the top and both sides of each bed. Pest populations were counted before the first spray application and 4 days after each application. On each sampling date, one mid-tier leaf was collected from each of the five randomly selected plants within each plot. A 2-square inch disc was cut out from the middle of each leaf and the number of aphids, eggs and nymphs of the silverleaf whitefly, larvae of the western flower thrips, and eggs and mobile stages of the pacific spider mite were counted under a dissecting microscope. Data were analyzed using Statistix software and significant means were separated using the Tukey’s HSD test. Results Efficacy of the pesticides varied against some pests on different sampling dates.

Aphid: There was a general decline in aphid populations during the study period and there was no difference (P > 0.05) among the treatments (Fig. 1). Specimens saved for aphid identification were lost, but they appeared to be melon aphids based on visual observation. Western flower thrips: The number of thrips nymphs declined in most of the treatments during the observation period (Fig. 2). However, significant differences (P = 0.0220) only after the second spray application were noticed where flupyradifurone treatment had significantly fewer thrips than B. rinojensis treatment (Fig. 2). There was a 92.5% decline by the end of the study, compared to the pre-treatment counts, from I. fumosorosea application, followed by 88.1% decline in flupyradifurone, 85.4% in VST-00634, and 82.9% in I1800AA at 10.3 fl oz. Pacific spider mite: There was an increase in mite eggs in all treatments after the first spray application followed by a decline after the second one without significant differences (P > 0.05) (Fig. 3) A similar trend was also seen in mobile stages in some treatments. The number of mobile stages was significantly different (P = 0.0025) only after the first spray, where untreated control, I. fumosorosea, B. rinojensis, and I1800AA at 20.5 fl oz had the lowest. When percent change in egg numbers from the pre-treatment counts were compared, only I1800AA treatments reduced egg numbers after the second spray with a 33.8% decline at 10.3 fl oz rate, 35.7% at 20.5 fl oz, and 60% at 17.1 fl oz. There was also a decline in the mobile stages after the second spray with 54.1% reduction in untreated control to 67.7% in I. fumosorosea treatment. Silverleaf whitefly: There was a general increase in the egg and nymphal stages of whitefly during the study (Fig. 4). Significant differences were observed in pre-treatment counts of egg (P = 0.0330) and nymphal stages (P = 0.0011), and after the second spray in nymphal stages (P = 0.0220). Compared to the untreated control, both flupyradifurone and sulfoxaflor resulted in a significant reduction in egg numbers after the first spray, whereas sulfoxaflor, B. rinojensis, and I1800AA at 20.5 fl oz reduced nymphal stages after the second spray. When the percent change from the pre-treatment counts was compared, only flupyradifurone and sulfoxaflor reduced whitefly egg numbers after both sprays. There was also a reduction in eggs after the first spray from I1800AA at 17.1 fl oz. However, there was a reduction in nymphal stages after the first spray in 42

All arthropod pests: When all data were combined for different pests and their life stages, flupyradifurone, sulfoxaflor, and I. fumosorosea resulted in a significant (P = 0.0001) decline in pest numbers compared to untreated control after the first spray (Fig. 5). Only flupyradifurone and sulfoxaflor caused such a reduction (P = 0.0048) after the second spray. In general, both the chemical pesticides (flupyradifurone and sulfoxaflor) provided effective pest control. The efficacy of the botanical extract was moderate to good depending on the pest, life stage, or the application date. Spider venom-based product also provided a good control while microbial products had a moderate impact in reducing pest populations. Although chemical pesticides appeared to be very efficacious, non-chemical alternatives were also effective. It is important to consider all these options to apply in combinations or rotations to obtain desired pest suppression without posing the risk of insecticide resistance. Although some insecticides seem less effective compared to others, rotating them with efficacious one, especially if the modes of action are different, reduces the risk of insecticide resistance. Botanical and microbial pesticides serve as valuable treatment options in an IPM strategy both in organic and conventional production systems. â&#x2013;&#x2C6; Authors' Acknowledgements: Thanks for the financial support of Arysta LifeScience, CertisUSA, Dow AgroSciences, and Vestaron, and the technical assistance of Neal Hudson.
