LEADERSHIP

CAPCA Leadership Update Rick Wescott, CAPCA Chairman

his being my first article in the CAPCA Adviser as your new chairman, I would like to start off by saying what an honor it is to be serving the CAPCA membership for the next two years. I do not take this lightly and will always do what is right and in the best interest of CAPCA and its membership. So at this point you may be asking yourself, “Who is Rick Wescott and where did he come from?” Well to my knowledge, I did not come from outer space, though some of the wackos we have to deal with in this business called agriculture may be from somewhere in outer space or worse. I grew up in Colusa, California on a 500-acre ranch, which I still own with seven family members. I attended Yuba Community College in Marysville for two years. From there I went to Cal Poly, San Luis Obispo, where I earned a degree in Agricultural Science. My first job out of college was with Salyer Land Co. in Corcoran. My next job was with the JG Boswell Company in Corcoran as an agronomist, which is where I first obtained my PCA license in 1982. In 1984 I started my career with Bayer CropScience, (we were called Mobay back in those days) and this February celebrated 34 years in my sales territory of Tulare and East

Fresno Counties. I also manage and grow 80 acres of oranges in Visalia where I live with my wife, Kim. We have a son, Josh, who is married to Tasha. We also have a two-and-a-halfyear-old granddaughter, Noel. The Executive Committee met in December to discuss the direction of CAPCA going forward and how it will look in the future. We discussed many issues, but the one that stood out the most was that CAPCA needs to change going forward. CAPCA can no longer only be concerned about what affects our pest control adviser license, but we must also be concerned about the issues that threaten all of agriculture and California’s green spaces. Going forward we will be partnering with other organizations where it makes sense, to support and defend agricultural issues that affect our ability to advise growers, to farm and feed the world through agricultural production and state resources, thereby supporting farming and healthy green spaces. Change is good and must be embraced to be an effective organization long into the future. As you can see, I have a passion for agriculture and will do whatever it takes to preserve it for many generations to come. Welcome to the future of CAPCA! T

PCA PROFILE

Chris Denning:

Finding Involvement in CAPCA Rewarding Joyce A Basan, Program/Communications Director

hris Denning currently serves as the President of the Desert Valleys Chapter of CAPCA. He received his B.S. in Agricultural Tech Management from the University of Arizona in 2001 and received his PCA license in 2002. He also is a California CCA and holds an Arizona PCA license. The major crops he consults in are lettuce, brassicas, artichokes, and spinach. Currently employed by Gowan Company USA, his position is the Desert Sales Rep in Arizona and Southern CA. Previous to that, Chris worked as PCA with Crop Production Services in Watsonville, CA (from 2007-2013) and as a PCA with Green Valley Farm Supply in Yuma, AZ and Gonzales, CA (20022006), advising in lettuce, broccoli, cauliflower, spinach, Brussels sprouts, and artichoke production. The importance of the role of the PCA was a key motivator in his choice to join the pest management profession. “I was interested in being a PCA because it is such an integral part of a crop being produced. You are monitoring the crop from the time it comes out of the ground until it goes into the carton or bin,” says Chris. “It’s a very satisfying feeling when you see a crop being harvested that you had a very important role in helping develop. I also like the fact you are communicating with all the aspects of production, from growers, to applicators, and harvesting.” Reflecting on his 14 years as a PCA, he recognizes the changes and challenges all PCAs face: “PCAs have a lot more on their plate than when I first started. They constantly need to think about food safety issues, whether the product they are using has an MRL for a specific country the packer/shipper may ship to. Many PCAs are also heavily relied on for their grower being compliant pertaining to groundwater contamination. It’s much more responsibility than just “walking fields,” but it also brings with it a valuable service that a customer can appreciate.” Downy mildew has been a difficult issue in lettuce and spinach in recent years for the desert. Chris explains: “Last season, PCAs reported much less pressure, but the two seasons before that were a nightmare. With the wet winter we’ve had, they are fighting it again this season. There are many good tools out there, but when the conditions are right, it seems like not much has a long residual control. Seed varieties are important but the disease is always adapting. Organic acres are constantly growing in Imperial Valley, many spinach fields have been lost because it’s such a difficult disease to overcome with conventional tools, let alone organic.” The ever changing technologies are also something Chris keeps up on. “The automation the lettuce industry has seen in the last decade is pretty impressive” he says. “From the robotic thinning machines that are being used more and more, to more automated harvest equipment. Many advances have been made with transplanting technology that requires less labor as well.” His involvement with CAPCA has contributed to his ongoing interaction in the industry and how he continues to educate himself. “As a manufacturer representative I sometimes rely on a customer who has more experience than I have with a particular product, or I contact

a university researcher. Who better to learn from on certain questions than the people who are using the products? As far as CAPCA helping with networking, my involvement in CAPCA has helped me establish deeper relationships with many of my customers and even some of my competitors. We all want to see our industry succeed, and CAPCA is something that brings us together for a common goal, whether it’s through putting on a CEU meeting or raising money for our annual golf tournament.” One area he wants CAPCA to keep playing an active role in is addressing the issues with public awareness. “After hearing this year’s key note speaker at the CAPCA Annual Conference about the disconnect our industry has with the public, I would love to see CAPCA continue to educate its members on how we can effectively get our message out there. I know I personally would like to be better educated on the scientific arguments to make when speaking to someone about GMO’s and bee health. It’s easy to make general statements, but I know that’s an area I would love for CAPCA to help educate its members on using science versus rhetoric.” Involvement in leadership is helping Chris improve his own professionalism and increase his contribution to the profession.

“I have a great respect for CAPCA members who are ‘field walking’ PCAs and involved with their local chapter.”

“Serving on the Desert Valleys CAPCA board and being more aware of industry issues is something that I feel has helped me greatly,” he says. “When I was a PCA in the field, I wasn’t as involved as I should have been. My excuse was always that I was too busy. I have a great respect for CAPCA members who are ‘field walking’ PCAs and involved with their local chapter. It’s a challenge to be involved when you are busy with your work, but it’s as important as ever. Even if the contribution of time is small, it’s something.” Chris is looking forward to the CAPCA State office’s new venture: the Spring Summit and networking event. “I think it’s great that CAPCA is going to hold a Summit this year in May for PCAs who are too busy to attend the Annual Conference in October. The Desert Valleys Chapter, and others, are going to benefit greatly from this. I really want to encourage the Desert members to attend and show support for something that was developed with them in mind.” In addition to serving as the President of the Desert Valleys Chapter, Chris serves on their Scholarship, Golf Fundraiser, and Continuing Ed committees. He also serves on the Arizona Crop Protection Association Board, the industry’s representation on government and legislative issues in Arizona, similar to CAPCA. T FEBRUARY 2017 | CAPCA ADVISER

Agriculture through the Eyes of U.S. Customs and Border Protection Joe Scheele and Samara Crenshaw, U.S. Customs and Border Protection

he U.S. agriculture industry accounts for more than one trillion dollars in annual economic activity. In California alone, farms and ranches received approximately $47 billion dollars in 2015 for their output. Invasive species cause more than $130 billion dollars per year in economic and environmental losses including yield and quality losses, according to a USDA Wildlife Services Economic and Ecological Impacts of Invasive Species, 2000 study. U.S. Customs and Border Protection (CBP) Agriculture Programs and Trade Liaison (APTL) is responsible for combatting the threat from invasive pests at land, air, and sea ports of entry. APTL provides leadership, expertise, and innovation to protect America and its natural resources from threats to agriculture while facilitating legitimate travel and trade. APTL is composed of four divisions: Agriculture Operational Oversight (AOO); Agriculture Bio-Terror Countermeasures (ABTC); Agriculture Policy and Planning (APP); and Agriculture Safeguarding. AOO oversees the agriculture mission to ensure a more consistent application of agriculture inspection policy across all CBP ports of entry and includes programs such as the Joint Agriculture Quality Assurance Program, stakeholder outreach, and Pest Risk Committees. ABTC develops programs designed to protect American agriculture from existing and emerging foreign biological threats. ABTC’s priority programs include educational awareness on agro- and bio-terrorisms and strategic biosecurity business transformation through technology. APP is responsible for the issuance of policy, planning, and guidance related to CBP’s agricultural mission and specialize in areas like Compliance Agreements and data integrity. Agriculture Safeguarding responds to complex passenger and cargo operational issues and provides direction on agricultural safeguarding procedures. More than 2,400 CBP Agriculture Specialists and 23,000 CBP officers at 329 ports of entry are responsible for enforcing more than 45 U.S. laws and regulations for several Federal agencies, including the United States Department of Agriculture (USDA). Together, CBP and USDA prevent the intentional and unintentional introduction of potentially harmful plant pests and foreign animal diseases from entering the United States via vigorous pest exclusion methods and technology. CBP and USDA continue to develop and deploy pest detection training to enhance detection and deter unwanted invasive species. Invasive insects and plants threaten California agriculture. These include the Asian Gypsy Moth (Lymantria dispar asiatica) that are often intercepted on cargo containers and conveyances and wood boring pests

CAPCA ADVISER | FEBRUARY 2017

found in non-compliant wood packaging material such as Cerambycidae and Curculionidae. Federal noxious weeds, such as Imperata cylindrica, or cogongrass also continue to threaten the state of California. One of the most invasive pests is the Asian Citrus Psyllid (Diaphorina citri Kuwayama). From 2010-2015, this insect has been intercepted more than 300 times throughout the Los Angeles, San Diego, and San Francisco Field Offices. The Asian Citrus Psyllid has also been detected by USDA in Alabama, Arizona, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, and Texas. The Asian Citrus Psyllid causes serious damage to citrus plants and citrus plant relatives through its feeding activities. Psyllids act as a carrier of the bacterium that causes Huanglongbing (HLB) disease. The psyllids spread the disease to healthy citrus plants as they feed. HLB was first detected in the U.S. in August 2005 in Miami–Dade County, FL. The University of Florida, Food and Resource Economics Department stated, “Since HLB was first found in 2005, orange acreage and yield in Florida have decreased by 26% and 42%, respectively. Orange production dropped from 242 million to 104.6 million boxes in 2014.1” According to the USDA, this disease can now be found in six states: California, Florida, Georgia, Louisiana, South Carolina, and Texas. Through stakeholder outreach and informed compliance, CBP is educating trade, industry, and the traveling public about the risk to the U.S. from foreign pests invading our agriculture, forests and natural resources. CBP continues to meet with the trade community, including importers, brokers, shippers and manufacturers. Through a cooperative effort, CBP can reduce the overall number of pests associated with international trade. For the U.S. and more specifically California, this is a priority. California

agriculture is vital part of the U.S. economy and the nation’s food supply. According to the California Department of Food and Agriculture (CDFA), over a third of the country’s vegetables and two-thirds of the country’s fruits and nuts are grown in California. Recognizing the role of California agriculture in feeding this country and mindful of the threats from abroad, CBP has deployed over 16% of its operational agriculture staff to California, including 25 agriculture canine teams. In an effort to educate the traveling public, CBP has partnered with the USDA and the Florida Department of Agriculture and Consumer Services in the Don’t Pack a Pest (DPAP) campaign. This effort began in 2010 as a multiagency project and originally focused on Florida and the 20 busiest airports in the U.S. for international traveler. The campaign involved the strategic placement of an educational video at the CBP primary booths, including those at the San Francisco and Los Angeles International Airports. The program has shown that educating the traveling public is extremely beneficial in assisting CBP’s holistic pest exclusion efforts. The DPAP campaign is now

being expanded in California. With the help of CDFA, CBP is adding additional DPAP signage throughout California’s international ports of entry including the Southern border. CBP is working on multiple fronts to push out the nation’s borders to exclude invasive pests from ever reaching the U.S. shores. The DPAP program has expanded to include the U.S. Virgin Islands, Puerto Rico, and has now been adopted by other Caribbean nations. CBP has also increased its presence and footprint through their preclearance programs abroad. CBP currently has agriculture preclearance programs in six countries - Aruba, Bahamas, Bermuda, Canada, Ireland, and the United Arab Emirates, and the agency expects to add a seventh country shortly. At these locations, CBP prescreens passengers before they board flights destined to the United States. The expansion of these programs abroad greatly reduces the pest risk by ensuring that invasive species never make it to our shores. The stakes are enormous, as California is a major tourist destination and a hub for international business. The state hosts the third- and eighth-largest passenger airports in the country, the nation’s largest seaport complex, and the busiest land border port of entry in the world. On an average day, more than 40,000 international travelers enter the U.S. through Los Angeles and San Francisco International Airports combined and over $600 million of imported goods enter the port complex of Los Angeles/Long Beach. At San Ysidro port of entry, alone, more than 90,000 people enter the U.S. every single day. Through outreach to the trade, industry, education of the traveling public, and expansion of our borders and frontline inspections, U.S. Customs and Border Protection continues to remain vigilant in its efforts to protect America’s agriculture and natural resources.

Many of you who attended CAPCA ED seminars in 2016 may have noticed the decrease in nutrient management topics at CAPCA ED seminars. The reason for this is DPR is no longer giving full credit for nutrient topics and CAPCA ED strives to offer at least six hours of continuing education credit at each meeting. As a result of this, the 2017 Nutrient Management Series offered in July and November will only be offering CCA CEUs. Thank you all for your support and we look forward to seeing you at our 2017 seminars! T

Complying with the Worker Protection Standard in 2017

he Department of Pesticide Regulation has revised Title 3 of the California Code of Regulations (3 CCR) to reflect the U.S. Environmental Protection Agency changes to the Worker Protection Standard (WPS). Compliance with the recently amended 3 CCR satisfies the revised Federal requirements. Effective January 2, 2017, employers of pesticide handlers and fieldworkers involved in the production of an agricultural commodity must comply with the following new requirements:

to employees (3 gallons per handler, 1 gallon per fieldworker); • Provide an eye washing station at mixing and loading sites when a pesticide label requires protective eyewear or mixer/loader is using a closed system; • Application exclusion zone for outdoor production of up to 100 feet depending on the application method; • Minimum age requirement of 18 years to apply pesticides or work in a field (early-entry) under REI.

• Provide annual training to fieldworkers (already required for handlers); • Maintain records of fieldworker trainings for two years (in addition to handlers); • Provide training records to employees upon request; • Post fields for any outdoor application with a restricted entry interval (REI) greater than 48 hours and post partially enclosed spaces with an REI greater than 4 hours; • Post Safety Data Sheets at the central display; • Post Pesticide Safety Information Series A-8/A-9 at all decontamination facilities servicing 11 or more workers; • Provide specified amounts of decontamination water

Additionally, certain exemptions have been removed including exemptions for employees performing crop advising tasks in a treated field under the guidance of a Pest Control Adviser and the exemption from wearing a respirator in an enclosed cab approved for respiratory protection. The newly revised regulations can be found on DPR’s website at: < http://www. cdpr.ca.gov/docs/legbills/rulepkgs/16-001/16-001.htm > Please note additional WPS related changes will go into effect in 2018 relating to additional training topic requirements for fieldworkers and handlers. For questions regarding these new requirements please consult your local County Agricultural Commissioner’s office. T

Water Board Agricultural Regulatory Programs Current Issues and Challenges

Johnny Gonzales, CalEPA, State Water Resources Control Board

alifornia agriculture is extremely diverse and spans a wide array of growing conditions from northern to southern California. California’s agriculture includes more than 400 commodities. The state produces nearly half of US-grown fruits, nuts and vegetables. Across the nation, US consumers regularly purchase crops produced in California. Many of the products are exported to markets worldwide. Water discharges from agricultural operations in California include irrigation runoff, flows from tile drains, and storm water runoff. These discharges can affect water quality by transporting pollutants, including pesticides, sediment, nutrients, salts (including selenium and boron), pathogens, and heavy metals, from cultivated fields into surface waters. Many surface water bodies are impaired because of pollutants from agricultural sources. Groundwater bodies have suffered pesticide, nitrate, and salt contamination. To prevent agricultural discharges from impairing the waters that receive these discharges, the Water Boards developed the Irrigated Lands Regulatory Program (ILRP) which regulates discharges from irrigated agricultural lands. This is done by issuing waste discharge requirements (WDRs) or conditional waivers of WDRs ( collectively Orders) to growers. These Orders contain conditions requiring water quality monitoring of receiving waters and corrective actions when impairments are found. The Water Boards acknowledge the vital and challenging work the agricultural professionals (e.g. Pest Control Advisers and Certified Crop Advisers and other technical service providers and farm advisers) perform to maintain agricultural productivity, which is key to our social and economic well-being in California. From the water resources perspective, the Water Boards applaud agricultural professional’s effort and commitment to evolve toward more sustainable management practices, and ongoing attention to the prevention of unintended effects of today’s agricultural operations. The Water Boards support and reinforce a spirit of cooperation and problem-solving between the water boards and agricultural professionals. PESTICIDES AND FERTILIZER ISSUES Pesticides: The Water Boards extensive monitoring programs identified several pesticides at levels of concern and have also identified several impairments on the federal Clean Water Act section 303(d) list that require a regulatory response. There are over 100 pesticides currently used that have been detected in California waters, and about 20 of these are found at levels exceeding standards, several others are at levels of concern. Part of the concern, especially given their widespread presence, is that the full effect of pesticides

CAPCA ADVISER | FEBRUARY 2017

in our waters is not known. Pesticides make it into the water via drift, runoff from rain and irrigation and very low levels can have impacts on aquatic life, like affecting the invertebrates at the base of the food chain. Because of these impairments and detections, pesticides and toxicity are a major focus of the Water Boards. Pesticides are becoming more of an issue in stormwater and wastewater regulation, and are a concern in forestry. The Water Boards have several total maximum daily load (TMDLs) and Basin Planning actions related to pesticide discharges. In urban areas, concerns include pyrethroids (esp. bifenthrin) and fipronil, and in agricultural areas concerns include organophosphates like chlorpyrifos and also pyrethroids. The Water Boards are also seeing several other insecticides and herbicides and fungicides in the water at potential levels of concern. Pesticides are a common cause of toxicity detected in receiving water monitoring. Their widespread detections also can be a concern for drinking water. Regional water quality control plans (Basin Plans) include several requirements regarding pesticides and their potential discharge to waters of the state, some of which include: 1. No individual pesticide or combination of pesticides shall be present in concentrations that adversely affect beneficial uses. 2. Discharges shall not result in pesticide concentrations in bottom sediments or aquatic life that affect beneficial uses. 3. Pesticide concentrations shall not exceed those allowable by applicable antidegradation policies 4.For toxicity, all waters shall be maintained free of toxic substances in concentrations that produce detrimental physiological responses in human, plant, animal, or aquatic life. Additionally, some specific numeric limits identified in the Basin Plan are chlorinated hydrocarbons, rice pesticides, diazinon and some metals used such as copper and arsenic. The State Water Board has reported the extent of pesticides impairment to USEPA in their 2012 Integrated Report as required by the Federal Clean Water Act Section 303(d). Sources of pesticide impairment is largely due to agricultural operations, however urban runoff has also been identified as a source. Pesticide impaired waters that are 303(d) listed: • 4,582 miles of rivers, streams and coastline • 793,253 acres of lakes, reservoirs, bays, estuaries, ocean and wetlands • These impairments are largely due to agricultural sources, but also may be from urban runoff

The 3 most commonly detected pesticides in groundwater above regulatory drinking water benchmarks. The three most commonly detected pesticides in groundwater are: • 1,2,3-Trichloropropane • Ethylene Dibromide • Dibromochloropropane These chemicals are most frequently detected in the Central Valley portion of the state. Fertilizers and Soil Amendments: Nitrate is one of California’s most prevalent groundwater contaminants, and can pose significant health risks at concentrations above the public health drinking water standard Maximum Contaminant Level (MCL) of 45 mg/L (as NO3). High concentrations of nitrate in groundwater are primarily caused by human activities, including fertilizer application (synthetic and manure), animal operations, industrial sources (e.g. wastewater treatment and food processing facilities), and septic systems. Agricultural fertilizers and animal wastes applied to cropland are by far the largest regional sources of nitrate in groundwater, although other sources can be locally important. Nitrate in groundwater affects public water systems and groundwater users, requiring treatment or alternative supplies, often at great cost. Small water systems, disadvantaged communities, and private domestic well owners may not be able to afford treatment or development of alternative water supplies. Due to California’s reliance on groundwater, and because many communities are entirely reliant on groundwater for their drinking water supply, nitrate contamination has far-reaching consequences. Solutions to nitrate-contaminated drinking water are achievable, but require additional funding and resources that are currently not available. Access to safe drinking water for every Californian will not take place without additional resources. REGULATORY STRATEGY As stated previously, the California Water Code authorizes the Water Boards to regulate discharges that impact or may have the potential to impact waters of the state. This includes both surface water and groundwater. Even though the Water Boards have regulatory authorities, the Water Boards find that a collaborative approach to outreach, education and implementation is just as important to the success of Water Board Agricultural Regulatory programs. Some of the agencies and groups that Water Boards partner with to leverage their authorities and responsibilities are: • Coalition and Commodity Groups • Third-Party Certification Groups • Farm Bureaus

• Natural Resources Conservation Services • USEPA • Resource Conservation Districts • Certified Crop Advisers • CA Department of Food and Ag • County Ag Commissioners • University of California Cooperative Extension • CA Department of Pesticide Regulation • CA Department of Food and Agriculture • Team Concept Water Quality Improvement Projects As an example of this collaborative team approach, education classes are often organized by coalition groups, with instruction provided by academia, resource agencies, or commodity groups. The classes are organized by crop type or watershed drainage area. The commodityspecific classes might include best management practice (BMP) instruction specific to a certain type of crop. The watershed–specific classes might be offered to a group of farms that all drain to the same monitoring location, and the classes would explain what types of BMPs are necessary to address specific pollutant exceedances, such as retention and infiltration BMPs for sediment-bound pesticides or nutrient management plans for excessive nitrogen. If we have willing producers and if we work together we can get results. Overall, growers can play a significant role in supporting the program. The Water Boards recognize that growers see themselves as stewards of the land and most want to work with us. Growers may not be happy paying fees and conducting monitoring, but the Water Boards anticipate that the growers see the multiple benefits that come along with protecting water quality, such as more efficient water and fertilizer use and associated costs. The next step of the Water Boards ILRP is better BMP implementation. We need to figure out how to work better with our coalition groups, technical service providers, and 3rd party certification programs to ensure that growers are actually implementing the BMPs they say they will. The Team Concept Water Quality Improvement projects mentioned earlier is an attempt to implement these approaches. Widespread non-point source (NPS) pollution caused by agricultural runoff cannot be addressed with scattered BMP implementation. It will take a watershed effort, drainage area by drainage area, where all growers will have to implement multiple BMPs before we start seeing results. The Water Boards recognize that having robust and viable agricultural operations in California is very complex and challenging. However the use of pesticides and fertilizers in crop production and the protection of water quality should not be in conflict. Therefore, we should seek to co-manage the goals of both. The Water Boards wish to ensure that California maintain sustainable crop production that does not undermine efforts to protect wildlife and water quality for current and future generations. T

Pest Control Through Plant Nutrition By: JW Lemons, Field Agronomy Manager, AgroLiquid

Author’s Note: Agriculture faces the challenge of feeding an ever-increasing population. To meet that challenge, the industry can use any help it can get. Mineral plant nutrition can play a significant role in pest management, and can be a substantial tool in meeting that challenge. This article is the first of a series, based on the response I have received from individuals attending the course I have been teaching for CAPCA ED called “Responsible Plant Nutrition and Pest Control.” As there have been requests for additional information, I will start this series covering potassium.

e know that Potassium (K) is a primary nutrient, critical for plant health. Potassium’s role is essential for the synthesis of proteins, starch, and cellulose in plants. Cellulose is a primary component of cell walls. Deficiency of this critical nutrient causes cell walls to become leaky, resulting in high sugar (starch precursor) and amino acid (protein building blocks) concentrations in the apoplast. When K is sufficient, there is an increase in the synthesis of the high-molecularweight compounds such as proteins, starches and cellulose. This depresses the concentrations of low-molecularweight compounds such as soluble sugars, organic acids, amino acids and amides in the plant tissue. These concentrations of low-molecular-weight compounds sustain development of infections and insect infestations. The lower concentrations of those compounds brought about by sufficient levels of K leaves a plant LESS vulnerable to disease and pest attacks. Adequate K increases phenol concentrations which play a role in plant resistance. The syntheses of other defensive compounds in K-sufficient plants have resulted in higher pest mortality according to research findings.

The role of potassium has been extensively studied. One study(1) reviewed 2,449 references, and found that the use of K significantly decreased the incidence of fungal diseases by 70%, bacteria by 69%, insects and mites by 63%, viruses by 41% and nematodes by 33%. Meanwhile, K increased the yield of plants infested with fungal diseases by 41%, bacteria by 57%, insects and mites by 36%, viruses by 78% and nematodes by 19%. If we look at some statistics (Table 1) on the impact of fungal diseases on world food supply, we can clearly paint a picture. Imagine what we could accomplish if we utilized the ability of potassium to aide in the control of pests such as Fungal, Viruses, Bacterial, Insect and Nematode. While additional studies need to be conducted, we should understand the importance of potassium in pest management. California has hundreds of important nutritional crops such as almonds, walnuts, tomatoes, grapes, various vegetables, melons, and fruit tree crops, just to name a few. All of them are at risk of reduced production from pest pressures. Integrated Management strategies should be used to select materials for pest control that have a minimum effect on human health. Imagine a tool that can help control multiple pests, improve the health of the plant, increase the productivity of the crop, and play the dual role of balanced plant nutrition and assist in your Intergrated Pest Management plan. Potassium (K) could be that tool. While this is only one nutrient, it shows the enormous potential nutrient management has in the IPM arsenal. T 1. Perrenoud S. Potassium and Plant Health. 2nd ed. International Potash Institute; Bern, Switzerland: 1990. pp. 8–10

TABLE 1 • More than 600 million people could be fed each year by halting the spread of fungal diseases in the world’s five most important crops (rice, wheat, maize, potatoes and soybeans). • Fungal infections destroy at least 125 million tons of the top five food crops each year, which could otherwise be used to feed those who do not get enough to eat. These crops provide the majority of calories consumed by humans. • The damage caused by fungi to rice, wheat and maize alone costs global agriculture $60 billion per year. • World scientists are calling for new solutions to prevent the spread of existing and emerging fungal infections in plants and animals. Limiting these infections would prevent further loss of biodiversity and food shortages, and plant nutrition is part of the solution. 24

Biopesticides Are in High Demand in Today’s Pest Management Programs

Tim Damico, Certis USA Executive V.P.—NAFTA

veryone is leaping onto the Biopesticide bandwagon. And, for good reasons. Although biopesticides are less than 5 percent of the global crop protection market, the estimated market for biopesticides worldwide in 2015 was estimated to be $2.7 billion. The market is conservatively estimated to grow 14 to 17 percent annually and is projected to reach $4.1 billion in 2018. It is the fastest growing segment in crop protection. Demand for Biopesticides North America (USA and Canada) represents 40 percent of the global demand for biopesticides. That demand is driven by a number of factors that include the increased interest in green agricultural practices, and the loss of many conventional products to reregistration and/or performance issues. Product development has also driven up demand for biopesticides. Today more and better biological active ingredients and products are available that can compete with, as well as complement conventional chemical pesticides. Demand, too, is driven by our increased knowledge about biopesticides and how to use them. More applied research and on-farm demonstrations are available than ever before. We’ve refined application rates and methods, and we have a better understanding of biological modes of action and how best to use them in pest management and crop production programs. Availability of biopesticides is important. There are more than 60 companies that are developing and/or selling Biopesticide products today. Biopesticides are Problem Solvers Biopesticides hold significant benefits for the PCA and the grower. Biopesticides offer: • Minimal impact on non-target organisms • Complex modes of action, so they are not prone to resistance and help reduce the development of resistance when used in resistance management programs • Pest control thereby enhancing crop quality and yields • Improved export opportunities, because most are residue exempt • An improved environmental profile, including low REIs and PHIs • Organically approved status that allows organic growers to control pests while maintaining their certified status One charge frequently leveled at Biopesticide products is that they are expensive. Like conventional pesticides, some BioControls do cost more to use per acre. But when biopesticides can solve a problem in the field, the products become cost-effective. Here are some real world uses of biopesticides: Growers are willing to purchase a low load copper product that costs two times the price of a traditional copper fungicide to solve REI and crop phytotoxicity challenges. Apple growers routinely add two different biologicals (yeast/bacteria) to counter fireblight resistance while preventing russetting. Corn growers spend $4 more per acre for a combination of conventional and biological pesticides to achieve early season disease and insect control with infurrow applications.

For Organic Production or Conventional More biopesticides are applied to conventionally grown acres than are applied on organic acres. But, the use of biopesticides has allowed growers of certified organically grown crops to meet the increasingly high demand for organic food. Organic food sales have grown at least 10 percent annually since 2008, and in 2015 its growth was 12 percent. Total organic sales were $27 billion in 2012 and today they are at $38 billion or 4 percent of the total industry. Biopesticides have found success and broad acceptance in the specialty agriculture, highvalue crops of vegetables, fruits, nuts and vines. Increasingly, as PCAs and growers of row crops examine the use of biopesticides, they will jump on the biopesticide bandwagon, too. T

UC IPM

Integrated Pest Management: Revitalizing and Reinvesting in a Proven Approach Peter B. Goodell, Area IPM Advisor and Cooperative Extension, UC Statewide IPM Program and Kearney Agricultural Research and Extension Center

or over 50 years, integrated pest management (IPM) has been a very successful approach to managing pests in complex systems. However, getting agreement on what IPM is, has been and will continue to be a challenge. IPM did not appear suddenly out of the void (Kogan, 2013). While IPM is most familiar as an approach to managing pests, it has also served society as an arbiter for addressing many complex societal issues involving pests, pesticides, and production. Defining IPM – How can three letters have so many meanings? Over the decades, IPM has defined in many ways. For example, Bajwa and Kogan (2002) identified 67 definitions for IPM. However, core characteristics of those definitions include: • Ecosystem based; • Long term prevention; • Combination of control techniques that minimize risks to humans, animals, and the environment; • Monitoring pests and assessing their threat to the crop or site; • Use of management or control techniques which present the least risk to humans, wildlife and the environment.

rationalize treatment, and selection of a management or control option to protect the crop or site from substantial economic damage. The sophistication of an IPM approach comes into play when more complexity is woven into the management approach(es). In this view, preventing the problem and creating an environment in which the crop is favored over the pest, has more reflection, planning, and complicated execution than merely “look, count, and treat.” All decisions are restricted by the conditions facing the IPM practitioner. How much risk is the client willing to accept? How many alternatives are available? What is the value of the threat versus the cost of treating? How quickly can the threat be moderated? How many other crises are being faced? Thus, the solution is not only technical but has very strong social and behavioral considerations.

The definition of IPM has been vexing because it means so many things to different people. IPM is not a monolith for solving a single problem but is a more conceptual approach. IPM is an approach, a philosophical, but pragmatic, description to managing system level issues. IPM is a platform from which we can consider options and launch solutions. IPM solutions are determined by the situation. Thus, there is no formula or recipe for IPM but rather it is a flexible approach that identifies the pest problem, evaluates the threat, assesses management options, and provides opportunity to learn, adjust, and continually improve. How much IPM is enough? If there is no hard definition against which we can measure IPM utilization, how does one know that IPM is being done? As stated, the situation determines the complexity of the solution (Kogan, 2013). Certainly, identification and monitoring are basic elements of an IPM program, as are the use of some decision threshold to 36

So, if the degree of IPM sophistication (e.g., number of practices employed) is left to the IPM practitioner, why would any progress ever be made beyond “look, count, and treat”? This is the very essence of the problem as well as the solution. IPM is a platform to consider options and launch solutions. In some situations, there are many options, chemical and nonchemical, and in others, very few. Depending on the situation, looking, counting and determining which is the most “benign” pesticide, represents the best IPM available. In other cases, where long term approaches are feasible more nonchemical approaches may be possible, such as selection of resistant varieties, modification of planting or harvest dates (to favor the plant not the pest), modification of irrigation timing/application, or use of hedgerows /vegetative strips (to increase biodiversity and natural enemy refugia). The drive to integrate “more” practices into an IPM program comes from the very need to demonstrate to society and policy-designers that we are using alternative practices, but still require a robust pesticide “tool box” (Goodell and Berger, 2014). Losing registration of active ingredients impacts IPM programs, but overdependence on these same active ingredients increases the public concern on their use. IPM is information intensive and requires continual updates to meet changes in production, regulation, and invasive pest threats. The foundation of IPM practices is science-based research and the great challenge over the past decade in California has been to maintain an independent and competitive grant process to seek solutions to existing and presumptive pest problems. The foundation of the UC IPM Pest Management Guidelines has been the research supported by its grant program during the 1980s and 1990s, as well as commodity, state, and federal support. The advantages of an independent competitive grant program are first, it is not driven by “problems du jour” and two, less advantage cropping systems have an equal opportunity for funding. How planning tools can help IPM address complex environmental and societal issues The IPM approach requires consideration of the complexity of the system—biological, ecological, and societal. Over the years, tools have been developed that addresses the immediate or long term pest issue, as well as processes to work through competing interests both internal and external to the situation. Since 2004, UC IPM and the Natural Resources Conservation Service (NRCS) have been working together to apply IPM to resource concerns related to pest and pest management activities (Anon., 2009). These tools include: • Development of Watertox (Anon., 2014), a tool modified from NRCS Pesticide Screening Tool which evaluates water related risks from insecticides; • Working from the Pest Management Guidelines, UC IPM created Year-Round IPM Programs (Anon., 2016), which 38

provided a seasonal approach to planning IPM around multiple pests and helped NRCS conservationists utilize IPM in addressing specific resource concerns; • Developing a workbook approach (Anon., 2011) for NRCS conservationists that reviewed and allowed incorporation of an IPM program as part of NRCS’ whole Farm Conservation Planning process; • NRCS and UC IPM supporting incentives for adopting IPM practice suites to address resource issues through EQIP (Environmental Quality Improvement Program) using these tools. In addition, the Decision Support Tool (Anon, 2015) was recently introduced for four crops that allows the entire Pest Management Guideline to be mined for all IPM practices for multiple insect pests and easily links to detailed information to many tools already highlighted. This tool provides a complete overview of pest identification, threat evaluation and assessment of management options. A printable report documenting the planning process is available or can be saved on portable mobile devices for later reference. This suite of tools provides a means to evaluate real time choices but more importantly, provide a method for continual IPM improvement by allowing the PCA and property owner to reflect on what they are doing, why are

they doing it, and what else could be done. By documenting this planning activity, progress over time can be measured and uses for specific practices elucidated. By using planning tools, PCAs and property owners can address multiple and complex environmental and human health issues and provide evidence of their planning process. Such evidence directly supports the California Environmental Quality Act (CEQA) requirement on a pesticide recommendation to: certify that alternatives and mitigation measures that would substantially lessen any significant adverse impact on the environment have been considered and, if feasible, adopted. Summary IPM is a flexible approach to managing complex system-level pest problems. It is not a monolithic set of rules but rather a methodology emphasizing prevention and long term management that emerges from reflective planning. It can fit both the immediate needs of site specific pest management as well as addressing broader environmental and regulatory issues. T

Fighting Plant Pathogenic Fungi with Entomopathogenic Fungi and Other Biologicals Surendra K. Dara, Strawberry and Vegetable Crops Advisor, University of California Cooperative Extension, San Luis Obispo; Sumanth S. R. Dara and Suchitra S. Dara, Global Agricultural Solutions, Bakersfield; and Tim Anderson, Dow AgroSciences, Shafter

lant pathogens are important factors that affect crop growth and yield and significant amounts of fungicides and fumigants are applied to protect crops from a variety of pathogens. In California, among all kinds of pesticides used between 1995 and 2014, fungicide/ insecticide use was consistently higher than the rest of the pesticides (CDPR, 2016). When fungicides and fumigants are also included, a significant proportion of millions of pounds of active ingredients is applied for controlling pathogens. Entomopathogenic fungi such as Beauveria bassiana, Isaria fumosorosea, and Metarhizium brunneum infect several arthropod pests on multiple crops (Wekesa et al., 2015; Dara, 2016) and are commercially available in multiple formulations. While entomopathogenic fungi are primarily used against insect and mite pests, several recent studies identified their role in improving plant growth and health (Sasan and Bidochka, 2012; Dara, 2013; Dara et al. 2016). Entomopathogenic fungi also appear to antagonize plant pathogens and some examples include B. bassiana against Fusarium oxysporum, Botrytis cinereal, Rhizoctonia solani and Pythium myriotylum (Bark et al., 1996; Ownley et al. 2008), Lecanicillum lecanii (=Verticillium lecanii) against cucumber powdery mildew, Podosphaera fuliginea (=Sphaerotheca fuliginea) (Askary et al., 1998), Lecanicillium spp. against plant pathogens and parasitic nematodes (Goettel et al., 2008), M. robertsii against Fusarium solani f. sp. phaseoli (Sasan and Bidochka, 2013).

While beneficial bacteria such as Bacillus spp., Pseudomonas spp., Streptomyces spp., and mycorrhizal fungi such as Glomus spp. and Trichoderma spp. are also available as commercial products to protect plants against pathogens, with their multipurpose use, entomopathogenic fungi could be play a potential role in crop production and protection. Considering the increased need for fumigation alternatives and preference for sustainable pest management practices, entomopathogenic fungi and other beneficial microbes could be potential choices in offering protection against soilborne pathogens. A greenhouse study was conducted using cotton and Fusarium oxysporum f.sp. vasinfectum Race 4 (FOV Race 4) as model plant and pathogen evaluating the efficacy of different microbe- or plant extract-based products. Materials and Methods Pima cotton seed of the variety susceptible to FOV Race 4 were planted in potting mix 0.33X103 CFU/g of FOV Race 4 in seedling trays. Healthy potting mix was used as untreated control. Six products, listed below, were applied in three regimens based on foliar application rate (10 ml of the treatment liquid calculated based on 100 gallons of spray volume/ac) or soil application rate (10 ml of the treatment liquid with product calculated based on the surface area of the cell at the soil application rate per acre) to each cell of the tray. Each treatment had 16 cells (or seedlings) and was replicated four times.

Soil application rate was calculated based on the surface area of each seedling cell (2.25 square inches) compared to one-acre rate and delivered in 10 ml of purified water with 0.01% of a nonionic surfactant. Foliar rate was calculated based on 100 gallons/ac spray volume and each cell received 10 ml. Untreated control and potting mix with plant pathogen received water with the surfactant. Regimen A - 10 ml of water or treatment liquid at soil application rate administered right after planting cotton seed. Regimen B - 10 ml of water or treatment liquid at soil application rate administered right after and 1 and 2 weeks after planting. Regimen C â&#x20AC;&#x201C; 10 ml of water or treatment liquid at foliar application rate administered right after planting. Seedling trays were arranged on a greenhouse bench and a sprinkler system irrigated trays for 5 min each day at noon. Plant health and growth conditions were monitored

3, 4, and 5 weeks after planting based on the following scale. 0 - Did not germinate or dead or necrosis of cotyledons/ leaves and hypocotyl/stem 1.0 - Stem green, but dying leaf/leaves 1.5 - At least one green leaf and cotyledons/other leaves necrotic 2.0 - Green new leaves and yellowing cotyledons/older leaves 2.5 - Green and bigger new leaves with slightly yellowing older leaves 3.0-4.5 - Varying levels of healthy plant 5.0 - Very healthy plant with optimal growth Data were analyzed using ANOVA model and significant means were separated using the Least Significant Difference (LSD) test. Results and Discussion In general, there was a positive impact of treatments on reducing the severity of FOV Race 4 in cotton seedlings, but it varied with time and among treatment regimens. Negative control plants did not show any symptoms of infection â&#x20AC;&#x201C; yellowing, necrosis, or wilting - and consistently maintained a high health rating of about 4.8 out of 5.0 (Table 1). Regimen A: Treatments were significantly different (P < 0.00001) on all observation dates, but when negative control was disregarded, differences were seen only on the first observation date, which was 3 weeks after planting. I. fumosorosea, M. brunneum, and S. lydicus resulted in a significant improvement in the plant health compared to the other treatments. On the following observation dates, plant health rating was higher in all treatments compared to the positive control with FOV Race 4, but the differences were not statistically significant.

Regimen B: In this regimen, where treatments were applied three times at a weekly interval starting from the time of planting, plants treated with I. fumosorosea, M. brunneum, and S. lydicus a better health rating than the positive control throughout the observation period. MBI 110 was also better than the positive control 3 weeks after planting, but not afterwards. Plant health in R. sachalinensis and B. bassiana treatments was better than FOV Race 4 alone, but it was not significantly different. Regimen C: This regimen aimed the impact of treating the soil with a higher concentration (based on foliar application rate) of treatments. B. bassiana-treated plants were significantly healthier than MBI 110, I. fumosorosea, S. lydicus, and FOV Race 4 alone on 3 weeks after planting and all the treatments (excluding the positive control) on 4 and 5 weeks after planting. Treatments compared among all regimens: When treatments were analyzed by combining all regimens, M. brunneum, I. fumosorosea, B. bassiana, and MBI 110 significantly improved plant health over FOV Race 4 alone, 3 weeks after planting (Table 2). However, B. bassiana provided significantly higher protection than all other treatments against FOV Race 4 during the rest of the observation period. Comparing regimens: Data were combined among all treatments and analyzed to compare the efficacy of different regimens. Multiple applications of beneficial microbe or plant extract based pesticides at low concentration or single application of a higher concentration were better than single application of lower concentration especially 4 and 5 weeks after planting (Table 3). Results suggest that non-chemical treatment options used in the study provide some level of protection against the plant pathogen FOV Race 4. It is very important to note that one or more entomopathogenic fungi antagonized FOV Race 4 equal to or better than other products that are based on beneficial microbes or plant extracts known to have fungicidal effect. Bennett et al. (2011) compared an endomycorrhizal product based on Glomus spp. with chemical fumigants (methyl bromide, chloropicrin, 1, 3-dichloroprepene, and metam-sodium) and solarization in multiple field studies. Efficacy of these treatments varied in different experiments and among cotton varieties. 42

While conventional treatments typically provided superior protection against FOV Race 4, mycorrhizae at times was comparable to some of the other treatments in some instances. Even if fumigants are used before planting for a healthy start, periodic soil treatment with beneficial microbes could help maintain plant health for the rest of the crop season. This is the first study where B. bassiana, I. fumosorosea, and M. brunneum were compared with other non-chemical alternatives against a plant pathogen and demonstrating their potential in offering plant protection. These results shed light in a developing area of science where alternative uses for entomopathogenic fungi are explored. Additional experimentation with different concentrations of the plant pathogen and beneficial microbes would expand our understanding of their interactions.

Abstract: Experiments were conducted to compare the mortality of a of glyphosatesusceptible (GS) Palmer amaranth (Amaranthus palmeri) plants to label rates of glyphosate, glufosinate, paraquat dichloride, saflufenacil, rimsulfuron, and a tank-mix of glyphosate + saflufenacil applied at the 4 to 6, 8 to 10, and 12 to 16 leaf stages. Complete control was obtained with all the treatments when they were applied at the 4 to 6 leaf stage but control was reduced with glyphosate and glufosinate at the later stages. The other treatments provided excellent control at all growth stages. Tank-mix combinations of saflufenacil + glyphosate, saflufenacil + glufosinate, saflufenacil + dicamba, rimsulfuron + glyphosate, tembotrione + glyphosate, flumioxazin+ pyroxasulfone + glyphosate, flumioxazin+ pyroxasulfone + glyphosate, dicamba + paraquat dichloride, and glyphosate + glufosinate were also tested on 8 to 10 leaf stage Palmer amaranth plants and all the combinations provided excellent control. Therefore, if growers desire to control this species with glyphosate- or glufosinate-alone then applications should be made by the 6-leaf stage; else, other herbicides or tankmix combinations tested in this study can be used for effective control. 46

CAPCA ADVISER | FEBRUARY 2017

Introduction: rowers in Californiaâ&#x20AC;&#x2122;s San Joaquin Valley (SJV) have reported poor control of Palmer amaranth (Figure 1) in orchards and vineyards (Figure 2) with glyphosate in recent years. Though, it is not known if these are cases of glyphosate-resistant (GR) populations or survivors of application of glyphosate at more tolerant stages of the weed. It has been reported that glyphosate application at the recommended label rate of 22 oz/ ac to weeds larger than 20 inches in height can lead to reduced control of Palmer amaranth (Nosworthy et al.,

2008). Therefore, a study was conducted in 2013 and 2014 to determine if Palmer amaranth populations of the SJV were GR or survivors due to application of glyphosate at more tolerant plant stages. Additional studies to evaluate the efficacy of alternative herbicides at various growth stages of Palmer amaranth were also conducted to develop information on options for rotation of modes of action. Methods: Screening for glyphosate resistance Seeds of Palmer amaranth were collected from 23 different locations of the SJV were poor control of the species with glyphosate had been reported. . The plants were tested for glyphosate resistance by making an application of a label rate of glyphosate (22 fl oz/ac of glyphosate + 2% v/v solution of ammonium sulfate at a volume of 40 gallons/ac) on 5 to 8 leaf stage Palmer amaranth plants grown in pots. Plant mortality was rated 21 days after treatment (DAT). An untreated control treatment was also included. Tolerance of plants to various herbicides applied at different growth stages in full sunlight Palmer amaranth plants from one of the locations were further evaluated for control with various herbicides at 4 to 6 leaf stage, 8 to 10 leaf stage, and 12 to 16 leaf stages. Plants were grown outdoors in 1 gallon pots and were treated with the herbicides when they reached the desired growth stages. The herbicide treatments included glyphosate (22 fl oz/ac), glufosinate (29 fl oz/ ac), paraquat dichloride (32 fl oz/ac), saflufenacil (1 oz/ ac), rimsulfuron (4 oz/ac), and a tank-mix of glyphosate (22 fl oz/ac) + saflufenacil (1 oz/ac). A non-treated control was also included. A nonionic surfactant (NIS) at 0.25% was added to the glufosinate, rimsulfuron, and paraquat dichloride treatments and a methylated seed soil (MSO) surfactant at 1% was added to the saflufenacil treatments. Plant mortality was rated at 28 DAT. Each treatment was replicated 6 times and the experiment was repeated.

Tolerance of plants to various herbicide tank-mixes applied at the 8 to 10 leaf stage Another study on mortality of Palmer amaranth plants treated at the 8 to 10 leaf stage with different postemergence tank-mixes was also conducted. Plants were grown outdoors in 1 gallon pots and treated with the herbicide combinations when they reached the 8 to 10 leaf stage. Treatments included in the study are shown in Table 1. An untreated control treatment was also included. Each treatment was replicated six times and the study was repeated. Results: Preliminary and secondary screenings for glyphosate resistance All the plants from the 23 different locations were completely controlled at the label rate of glyphosate. Therefore, these populations were deemed to be glyphosate-susceptible. Tolerance of plants to various postemergence herbicides applied at various growth stages At the 4 to 6 leaf stage all the herbicides tested, except rimsulfuron, provided complete control of the Palmer amaranth plants by 28 DAT. At the 8 to 10 leaf stage, the control of the Palmer amaranth plants treated with glyphosate or glufosinate was reduced. Results at the 12 to 16 leaf stage were similar to the 8 to 10 leaf stage (Figure 3). Therefore, saflufenacil-alone, saflufenacil + glyphosate, and paraquat can provide complete control of Palmer amaranth up to the later growth stages evaluated in this study. Glyphosate-alone and glufosinate-alone could still be used for effective control of the SJV Palmer amaranth populations provided that they are applied before the 8 to 10 leaf stage. Estimated cost of each of the herbicide treatments are also provided in the legend in Figure 3.

Mortality (% control) of Palmer amaranth plants treated with various herbicides at the 4- to 6-, 8- to 10-, and 12- to 16- leaf growth stages. Estimated costs of the herbicides per acre in each treatment above were $ 15.40, $17.40, $ 2.00, $ 9.70, $ 23.08, $ 56.70, respectively.

Tolerance of plants to various postemergence herbicide tank-mixes applied at the 8 to 10 leaf stage All the herbicide tank-mix combination tested provided complete control of the plants by 28 DAT when the application was made at the 8 to 10 leaf stage of the plants (Table 1). Therefore any of these tank-mixes can be used for effective control of Palmer amaranth plants in the SJV depending on the cropping system and if the herbicide is labeled for that particular system. However, cost of these tank-mixes may be a constraint; thus, approximate costs based on estimates provided by pesticide dealers is provided in Table 1. In conclusion, this study showed that none of the SJV Palmer amaranth plants that were collected for this study were GR and, in the current context, glyphosateescapes observed in the field were probably because of the herbicide being applied at later growth stages of the plants. Palmer amaranth control with most of the herbicides tested was greater at the 4 to 6 leaf stage than at the 12 to 16 leaf stage, especially with glyphosate. This may be a major reason why poor control of Palmer amaranth with glyphosate could have been observed. Several herbicides notably saflufenacil, mixture of saflufenacil + glyphosate, and paraquat were identified as alternatives to glyphosatealone for control of Palmer amaranth. Further, several tank-mixes for excellent control of Palmer amaranth were also identified. Several, but not all, of these herbicides are registered in orchard and field crops in California. Complete details of this study are available in Rios et al. (2016). Control methods of the most frequently occurring and troublesome weed species, such as Palmer amaranth are rapidly being lost because of overall lack of stewardship and continuous use of the same mode of action. Consequently, GR Palmer amaranth was recently confirmed and documented from one location in California and will continue to spread if pro-active measurements are not taken (Heap 2016). T 48

CONTROL TOUGH WEEDS WITH WEATHER-READY CHATEAU® HERBICIDE

Chateau Stays Put and Won’t Photodegrade Waiting to be Activated by Rainfall or Irrigation Almond and grape growers face many challenges during each season, and in recent years the challenge for adequate rainfall has been paramount. Growers need not worry about their residual herbicide application timing if they choose Chateau® Herbicide. While many herbicides begin degradation as soon as they are applied, Chateau does not. Chateau takes a little water to get its activity running—either by rainfall or irrigation—only a 1/4 inch is required. “Water conservation has long been top of mind for California growers and is more critical now than ever before,” said John Pawlak, product development manager at Valent U.S.A. Corporation. “Growers want to keep their trees and vines watered while conserving resources.”

CHATEAU IS A WEATHER-READY AND FARM-READY HERBICIDE THAT STAYS WHERE YOU PUT IT AND WON’T LEACH, CO-DISTILLATE OR PHOTODEGRADE. THE LONGLASTING RESIDUAL CAN REMAIN ACTIVE ON THE SOIL FOR UP TO 12 WEEKS AFTER THE APPLICATION WITH NO RAINFALL. “Chateau gives growers a little bit more flexibility in when it’s applied,” Pawlak said. “It gives growers and PCAs the peace of mind that if they apply Chateau and it does not rain, that it will remain active until the rain event or irrigation is turned on.” Chateau allows growers to focus their attention on promoting a strong crop by controlling nutrientand water-robbing winter annual broadleaf and grass weeds. The proven, broad spectrum power of Chateau keeps more than 90 labeled weeds at bay in orchards and vineyards. Chateau has been used commercially since 2005 with excellent

reliability and proven, dependable weed control in various weather conditions. Chateau is a PPO inhibitor with a different mode of action than other chemistries that allows it to help growers fight resistance while providing long-lasting control of tough weeds. “Chateau is a better choice for a preemergence herbicide in orchards and vineyards because its broad spectrum control can be used on most every tree, fruit, nut and vine crop, including new plantings,” Pawlak said. “Growers can count on its powerful chemistry to not be broken down by sunlight, perform once rainfall or irrigation occurs and keep weeds at bay throughout the growing season.”

New Boron-Molybdenum Molecule Improves Mobility and Mixability with Foliar Applied Chemicals and Fertilizers California Field Trials Show Significant Increases in Harvest Weight and Yield Smarter Nutrient Delivery

CA Field Trials: June, 2016

Over the past couple of years, BRANDT has been developing and testing a new proprietary boron-molybdenum formulation that was designed to improve mobility and increase compatibility with calcium, zinc and many of the pesticides that are sensitive to alkaline hydrolysis.

“Foliar boron applications typically become fixed and have limited mobility; so to be able to protect this boron molecule when it comes in contact with other chemicals is a huge accomplishment. The benefits of this are two-fold in that we get better mobility and improved tank mixability”

Earlier this spring, BRANDT conducted field trials to test BRANDT® SMART B-MO™ on lettuce and kale in California. “The results

were outstanding. We saw a significant increase in harvestable weight and estimated yield in the crops treated with BRANDT SMART B-MO,” said Research Associate, Andrew Pederson. “We also conducted tissue tests that allowed us to evaluate the efficacy and mobility of the BRANDT® SMART B-MO™ application. Our conclusion is that BRANDT® SMART B-MO™ was able to deliver more boron to the plant, than other forms of boron” said Pederson.

said Brian Haschemeyer, Director of Discovery and Innovation at BRANDT. The new boron molybdenum formulation allows growers to get more products into one tank mix, which saves a lot of time and money on applications. Adding BRANDT® SMART B-MO™ to tank mixes can be highly beneficial as boron (B) it is critical in development of cell wall strength, cell division, fruit and seed development and sugar transport. Molybdenum (Mo) is essential for nitrogen fixation, which allows plants to process nitrate nitrogen more efficiently. BRANDT’s proprietary boron and molybdenum formulation is part of the BRANDT Smart System product line and will be marketed under the name BRANDT® SMART B-MO™.
