LEADERSHIP

CAPCA Update John McClenahan, CAPCA Chair

he fall is approaching fast and we are closing in on CAPCA’s 41st Annual Conference & AgriExpo, the 2015 DPR license renewal period, and also addressing leadership needs within our association and issues in the pest management industry. Our annual conference is at a new venue this year, the Grand Sierra Resort in Reno, NV. With the continued growth and participation in our conference, a new location was needed to facilitate our expanding needs. For example, this year at conference we will have over 180 exhibit booths in our trade show. This activity provides additional continuing education (CE) and networking opportunities along with our general and breakout sessions that have excellent presenters highlighting timely and important topics in pest management. Review the conference information starting on page 22 and in the enclosed conference program. Worth noting is that the label update on Sunday provides for several hours of laws as well as other CE hours and we have 22 presenters. We hope to see you there in October. Our CAPCA ED CE seminars continue to grow. Check out the update on our agenda topics and events planned for our growing program on page 42. Contact our event coordinators for additional information on these valuable educational training opportunities. CAPCA ED and our Chapters are providing some of the best speakers and subject matter that is available. Please take advantage of your “in house” resources to get your hours. The Board has also been actively representing the PCA license with the Department of Pesticide Regulation (DPR) regarding the important issue for DPR to maintain adequate review procedures to validate the CE training attended by members.

CAPCA ADVISER | OCTOBER 2015

This is a crucial component to ensure that the highest level of professional education is achieved. How DPR views the validation of attendance and utilized the CE documentation is an important topic for CAPCA to continue to articulate to DPR so that we as an association continue to maintain the highest level of knowledge and professionalism in the industry. We have just completed our 2015 Demographics Survey. Thank you for responding and providing us with a snapshot of who we are, what we are focused on, and ideas to improve the direction of the Association. Results from the survey will soon be posted on the CAPCA web site: www.capca. com The CAPCA Board of Directors is actively engaged in supporting all of our members and the search for a new CEO is underway, with the goal of beginning review of applications in late September/early October. A job posting for the position is included in this magazine beginning on page 78. Ideally, we hope to have our new President on board by January 2016. Important issues impacting our regulatory challenges that are being addressed by CAPCA’s Government Relations Committee are outlined by the chair of that committee, Henry Buckwalter, on page 8. Please take a moment to review this update that includes vital information for the PCA license and the future of pest management operations. Thank you for being a CAPCA member and supporting the Association through your leadership and volunteer commitments. T

Government Relations Update Henry Buckwalter, CAPCA Government Affairs Committee Chair

Category H egrettably, after more than two years of research of existing statutes and regulations as well as the assembly of proposed language, CAPCA has suspended the pursuance and tabled indefinitely a new Category H titled Soil and Plant Health. CAPCA had also proposed legislation, which Assemblyman Luis Alejo generously sponsored to assist in the creation of the new category. In late 2013, the Board approved the creation of an exploratory committee to research the establishment of a Category H. The primary motivation for CAPCA members was the soon-to-be adoption of 100% use reporting for fertilizing materials required of growers by the Regional Water Quality Control Board’s Nutrient Management Plans. The exploratory committee researched the existing statutes and regulations for the adoptability or feasibility of language for a new category (H) “Plant and Soil Health”. The committee met with CDFA Secretary Karen Ross and senior department staff. We were encouraged by the reception of the concept of such a Category H. However, the committee recognized that CDFA regulates the licensure and revenue generation for fertilizers and related materials, but not the recommendations for their application under the “functional equivalency” of CEQA. Our team then met with the Department of Pesticide Regulation (DPR) Director Brian Leahy and senior staff on two occasions and, although the concept of a category for Soil and Plant health was recognized as warranted due to the Water Board’s regulatory requirements, DPR’s legal counsel took the position that they have no statutory authority over the environmental protection 8

Henry Buckwalter, CAPCA Government Affairs Committee Chair of Plant and Soil Heath, even with the knowledge that DPR is part of the California Environmental Protection Agency, as is the State Water Resources Control Board. DPR was unwilling to advance the request for the development of a new PCA category. To their credit, DPR did formulate the possibility of a PCA category for IPM; however, CAPCA recognizes the importance of IPM and acknowledged to DPR that, as PCAs, we have a long involvement in recognizing and including IPM in all of our recommendation decisions and would be more than happy to comment on any policy proposals DPR may have going forward for IPM. School Buffers DPR hosted several workshops around the state to address pesticide use near schools. CAPCA testified as an organization as well as several individual members indicating that the additional regulations are not warranted due to the lack of incidents data and basic science. The regulatory concepts include: ▸ Increased communication through notification to schools • Of intended application of certain

pesticides • Made when school is in session • Within a certain proximity to a school ▸ Reduced risk of exposure by additional restrictions on applications • Of certain pesticides • Made using specific application methods • Within a certain proximity to a school Examples of current requirements of the Healthy Schools Act include: ▸ Requirements for pesticides applied at schools ▸ Notification • Posting • Reporting • Prohibits products with conditional, experimental use, and interim registrations • Integrated Pest Management (IPM) plan and training by 7/1/2016 The proposed timeline: ▸ December 2015 – DPR proposes regulation for formal comment ▸ February 2016 – Public hearings on proposed regulation / CAPCA needs to comment ▸ December 2016 – Final regulation submitted to OAL for review ▸ April 2017 – Regulation becomes effective National Strategy to Promote the Health of Honey Bees and Other Pollinators President Obama issued a memorandum on June 20, 2014, calling upon Federal agencies to increase and coordinate their efforts to improve bee health by developing an integrated strategy. The strategy was released on May 19, 2015. EPA’s Proposal to Mitigate Acute Risk to Bees – Commercial Pollination includes: ▸ Label restriction prohibiting applications while bees are onsite under contract for pollination services

First Step for a Clean Spring: Fall Weed Control DuPont™ Matrix® SG herbicide delivers residual control of winter annuals and early-season weeds for a clean start in spring.

Tips for Fall Weed Control Roncoroni recommends the following tips for weed control that starts in the fall and lays the groundwork for season-long control. • Make a fall herbicide application. Control weeds that germinated in the fall with a postemergent herbicide application. If a systemic herbicide is used, use precaution against drift onto leaves and green bark. Apply a preemergence herbicide if moisture is available for soil incorporation.

• Clean up under vine rows. In winter, remove fallen leaves and debris from under vines with a blower. This will improve herbicide-soil contact and maximize herbicide results.

• Time herbicide applications with predicted rainfall events. To be effective, a preemergence herbicide needs at least 0.25 inch of moisture in a single event within a month to incorporate into the soil.

• Manage resistance. Rotate active ingredients and tank-mix products with different modes of action to avoid herbicide resistance development.

Adjusting Weed Control for Welcome Spring Rain The spring season is still months away, but growers should start planning their spring weed-control strategy now, says Roncoroni. El Niño is expected to bring much needed rain to California next spring. While welcome, that extra precipitation will affect weed control. “We may have rain or moisture that lasts into the summer. If we have a very serious rain amount in the winter, growers need to think about how they’ll control weeds at or just after bud break if they can’t get into fields because they’re wet.” Roncoroni notes that, in the case of a wet spring, Matrix® SG would be an effective option. Unlike some herbicides, Matrix® SG can be applied after bud break. “If growers are unable to get into fields because of rain and need to spray later, Matrix® SG would be a good fit,” he says.

Get More Control With Matrix® SG DuPont™ Matrix® SG herbicide stops tough weeds before they can gain a foothold on vines. • Controls annual grasses and broadleaf weeds such as hairy fleabane, marestail, redstem, whitestem, filaree, malva (cheeseweed), common chickweed, annual sowthistle, prickly lettuce, London rocket, burclover, panicle willowweed, annual bluegrass, Italian ryegrass and more. • Provides partial control of yellow nutsedge. • Is labeled for use in grapes, citrus, tree nuts, stone fruit and pome fruit. • Is formulated with soluble granules that fully dissolve for effective weed control and easy tank clean-out. • May be combined with other tank-mix partners for extended soil residual activity and a broader weed-control spectrum.

ever give weeds a head start. That’s the key to good vegetation control in California vineyards, says John Roncoroni, weed science farm advisor, University of California Cooperative Extension, Napa County. “By the time growers apply herbicides in the spring, some weeds have already been growing for three months and are harder to control,” he says. For clean vine rows in spring, Roncoroni recommends a herbicide application in the fall, following mid-winter and, if needed, mid-summer applications. “If growers make a fall application to clean up the rows before heading into winter, they will have much better weed management the following season.” An effective vineyard weed-control option is DuPont™ Matrix® SG herbicide. Applied preemergence, Matrix® SG helps keep rows clean long into the season. As part of an integrated weed-management plan, Matrix® SG helps minimize weed seed banks and control tough problem weeds, including glyphosateresistant marestail (horseweed), hairy fleabane, filaree, malva, sowthistle, annual bluegrass, Italian ryegrass and more. Matrix® SG also provides suppression of yellow nutsedge. The low use rate of 4.0 ounces per acre and flexible application options make Matrix® SG an ideal fit for most grower programs.

CAPCA & AgSafe

Creating Industry Solutions Together

Amy Wolfe, President and CEO, AgSafe

he Greek philosopher Heraclitus got it right when he noted that the only thing that is constant is change. This is true in all aspects of life but seems particularly poignant in today’s agricultural industry. The state legislature is in full swing creating new laws while enforcement agencies are evaluating existing regulations and considering modifications. For the agrochemical community, both the California Department of Pesticide Regulation (DPR) and the U.S. Environmental Protection Agency (EPA) are proposing a variety of changes in the coming year. The leaders of both agencies strongly believe that field workers must be knowledgeable about pesticide safety and how it applies to their work in order to prevent exposure. DPR announced in June that

in early 2016 it will undertake the rule making process to specifically address worker training requirements. The proposed change would mandate that all field workers working in fields treated with pesticides be trained on an annual basis. In February 2014 EPA “proposed changes to the agricultural Worker Protection Standard (WPS) to increase protections from pesticide exposure for the nation’s 2 million agricultural workers and their families. This is an important milestone for the farm workers who plant, tend, and harvest the food that we put on our tables each day.i” As recently as early summer, EPA had hoped to have their process finalized by the fall of 2015 to take effect next year. Irrespective of EPA’s outcome and timeline, DPR is moving forward early next year with their process to change the farmworker training requirement to once each year, which is a 400% increase from the current regulation that requires training once every five years. This change will have a significant impact to both growers and farm labor contractors (FLCs), both of whom have a responsibility to make sure their workers are adequately educated. In particular, if a grower is using an FLC, joint employer liability regulations also require that the grower confirm worker training has been conducted by the FLC or they can and will be held responsible. Creating Solutions Together For the past few years, CAPCA and AgSafe have been working together to provide the industry with diverse training solutions.

As a partner organization, AgSafe extends select educational programs to CAPCA members at an AgSafe member rate as a way to enhance professional development by addressing a broader scope of issues impacting the agricultural industry. One example of this is our Pesticide Handler Safety and Risk Management Program, which provides farm owners, farm labor contractors, and human resources and safety professionals the knowledge and resources to teach workers WPS and DPR-compliant training. The Program is a critical step in ensuring that enough individuals are qualified to provide the soon-to-be annual training. Our organizations’ education collaboration on this regulatory shift is just one way CAPCA and AgSafe are monitoring industry trends and creating valuable solutions for our members, as well as the industry as a whole. At the 41st Annual CAPCA Conference & Agri-Expo I will share other issues we are monitoring, along with practical steps to address those challenges during my session “Scaling the Mountain of Worker Safety Compliance.” The AgSafe Education Team will also be available during the event at the AgSafe booth to answer your questions and register you for the Pesticide Handler Safety and Risk Management Program. Why AgSafe Some of you may wonder, why a partnership with AgSafe given CAPCA’s rich history and experience. The answer, in this ever-competing market, is value-added leverage.

alibrate

Early Season Kalibrate applied at planting time or side-dress is taken up from the soil along the length of young roots, particularly by root hairs. Potassium moves to leaves and fruit via the phloem and xylem, and is transported in all directions between plant organs in response to metabolic demand.

Mid-Late Season Sure-K as a foliar application or fertigation enables the flexibility to provide available potassium, which is actively taken up by plant tissues. Sure-K enters the plant more effectively than conventional potassium fertilizers and has excellent crop safety. Once in the plant, Sure-K is rapidly transported and redistributed to areas of greatest metabolic demand. Sure-K can also be mixed with crop protection products, reducing the number of passes on the field.

Provide the potassium your crop needs, when it needs it, by using the most efficient potassium nutrient products on the market: Kalibrate and Sure-K. These products provide available potassium to the plant at the right times in the growth cycle â&#x20AC;&#x201C; despite the drought. Learn more at agroliquid.com/Kchallenge

Sustainable/Organic Production Seminars

Sustainable/Organic Production Seminar August 13th in Tulare, CA

he California Association of Pest Control Advisers (CAPCA), local CAPCA Chapters and the Organic Fertilizer Association of California (OFAC) have continued a partnership, which began in 2008, of presenting Sustainable/Organic Production Seminars. Thirty-one seminars have been held throughout

the state since the first that took place in Salinas, CA. We already have had seminars this year in San Marcos, Oxnard and Tulare with full houses and sold out exhibit space at each one. The seminar program would not be a success without the support of our sponsors and exhibitors. Many of them have been involved in the

programs since day one. Also having exhibits allows the attendees to visit with firms that have products that are used in sustainable and organic production. This year is the International Year of Soil and presentations on soil health have been prevalent at all of our programs. Healthy soil

Return Your DPR License Renewals Early!

he Department of Pesticide Regulation (DPR) recently sent out renewal packets to businesses and individuals with names that start with M-Z to renew their licenses/certificates. Did you know at the height of the renewal season it can take six weeks to process applications? So it is vital that all applicants send their complete application by November 19 to get a license by January 1.

Benefits to returning your renewal application by November 19: • You will receive your new license by January 1! Remember you cannot legally buy, sell, or apply pesticides or make pesticide recommendations without a certificate or license. • It allows enough time to resolve issues or discrepancies found in an application. This includes the applicant not having enough DPR approved continuing education (CE) hours, incorrect payments, or missing or incorrect information. • You avoid paying late fees. Do you know if you have enough CE hours to renew? Each year, license and certificate holders attend courses that were not approved for CE credit by DPR. These courses will not count towards your CE hours for renewal. However, if you submit your application before November 19, DPR can help to sort out any discrepancies. Failing to have enough CE credits by December 31 will require retesting. If you have questions about your 2014-2015 CE hours, contact the individual course sponsor, your professional association, or refer to DPR’s Web site for approved courses and sponsors’ contact information: www.cdpr.ca.gov/docs/ license/cont_ed_cfm/classes.htm

Don’t Become a Statistic! A look back at last year’s renewal season:

Individual License and Certificate Holders • DPR mailed 13,919 renewal application packets. • Less than one third of the renewal applications were returned to DPR by November 19, 2014. • Only half of all renewing applicants received their license or certificate by January 1, 2015 and were legally allowed to keep working.

Pest Control Business License Holders • Only 35% of the license renewal applications were received by DPR by November 19, 2014. • 53% received their new business license by January 1, 2015 and could continue to operate.

Business License Reminder: Remember, a DPR licensed pest control business whose license expires this year can only be renewed after their qualified applicator license is renewed. Don’t become a statistic! Send in your completed renewal application to DPR early (by or before November 19, 2015) to ensure your license will be renewed before you need it in January! 20

We will be focusing on ways to elevate the role PCAs play in new cropping systems, new technology, and emerging regulations. As we are faced with new and emerging challenges, we need to step up our knowledge, skills and professionalism if we’re going to conquer the summit of California Agriculture. This should prove to be another fantastic event built on the success of last year’s Conference. The CAPCA Conference has been continually growing in size and scope over the past several years and this year’s conference is going to be the largest yet. We’ve expanded the Expo space to accommodate more vendors than ever so we can learn about the latest innovations in the agriculture industry. We’ve kept the third breakout session on Tuesday allowing us to provide a greater variety of crop specific educational presentations. This year we have been able to offer a total of 17 CE Hours; 5.5 Laws and Regulations and 11.5 Other. In addition, there will be 15.5 CCA hours offered along with CEUs for GCSAA, CDPH, ISA, CCN Pro, Nevada and Arizona. This event will be a great opportunity to get the latest information from some of the top experts in the industry, re-connect with colleagues, and have a great time. This year’s Conference starts on Sunday with an Expanded Label Update followed by the Welcome Reception sponsored by Gar Tootelian. The Monday Morning General Session begins with remarks from the Presidents of CAWG, the Almond Board and the Strawberry Commission on the states of their respective industries. The morning session will continue with Jim Blome, CEO of Bayer CropScience, providing a global perspective on the crop protection industry. At the Dow AgroSciences Membership Luncheon, we will recognize this year’s CAPCA Member of the Year and Outstanding Contribution to Agriculture Award winners. Our Keynote Speaker, American climbing great Chris Warner, will regale us with stories of survival and perseverance on some of the world’s most dangerous peaks. Monday’s Afternoon General Session looks at the ever-changing regulatory environment of pesticide enforcement, spray drift and worker safety and concludes with 2 hours of Exhibit Hall time with an exciting Scavenger Hunt for some fantastic prizes. The always popular DuPont Monday Night Football Party rounds out Monday’s events. Tuesday is breakout day with 3 half-day sessions devoted to Production Ag, Turf & Ornamental and Water/Drought issues. Conference will conclude with my remarks as Conference Chair revisiting this year’s conference and looking forward to next year. I would like to thank and recognize all the people and organizations whose support continues to make the CAPCA Annual Conference the number one Ag Industry event in California. I look forward to seeing everyone in Reno this October.

Drought Impact on Water Rights in California Johnny Gonzales, CalEPA, State Water Resources Control Board

f your food was grown or raised by California farmers or ranchers, you depend on someone who either has a Water Right or buys water from a water supplier who has a Water Right (such as an irrigation district). If you live in the city or suburbs and drink, cook with, wash with, or water your yard with water, you are able to do so because your city has a Water Right or buys water from someone who has a Water Right. When you turn on your lights or use appliances in California, it is likely that at least some of the electricity you are using was generated by a power company that is able to operate a hydropower plant because it has a Water Right. If you swim, fish, or boat in a man-made lake or raft below a dam, you are able to do so because the owner of the dam has a Water Right. Dry is the new normal, or so some predictions say. Given current drought conditions and competing demands for water in California, it is more important than ever before that the Water Boards strategically use their full range of authorities and funding capabilities to enact policies that address water supply and environmental protection in a coordinated manner. Doing so requires an understanding of how streams and species react to variable flow conditions and opportunities for improving flow conditions while still providing for critical human needs. All Californians should have an interest in water-shed issues in our state.

CAPCA ADVISER | OCTOBER 2015

eWRIMS provides the public and staff Internet access to Californiaâ&#x20AC;&#x2122;s water rights information by combining a tabular database with a Geographic Information System database system.

During times of drought, vegetation is visibly dry, stream and river flows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. As drought persists, longer-term impacts can emerge, such as groundwater level declines, land subsidence, seawater intrusion, and damage to ecosystems. Unlike the immediate impacts of drought, however, longterm impacts can be harder to see, but

more costly to manage in the future. One key area in dealing with the current 5-year drought we are facing, involves Water Rights. What is a Water Right? A Water Right is legal permission to use a reasonable amount of water for a beneficial purpose such as swimming, fishing, farming or industry. If you take water from a lake, river, stream, or creek; or, from underground supplies for a beneficial use, the California Water Code (Division 2) requires that you have a Water Right. The State Water Board is the only agency with authority to administer Water Rights in California. Local governments, water districts, and the California Regional Water Quality Control Boards do not administer Water Rights. The State Water Board shares the authority to enforce Water Right laws with the state courts. The State Water Board encourages Water Right holders to assist in the prevention of unlawful diversion of water and in discouraging any waste or unreasonable use of water. The Web-based Enhanced Water Right Information Management System (eWRIMS) was developed by the State Water Board to track information on Water Rights in California. eWRIMS contains information on Water Right permits and licenses issued by the State Water Board and other claimed Water Rights. eWRIMS is also a module of the State Water Boardâ&#x20AC;&#x2122;s California Integrated Water

Just Add

WATER? In a drought, the last thing you need is a soil amendment that doesn’t even work without adding water. It takes 60 gallons of water to make a single pound of gypsum soluble enough to do your soil any good. Gypsum is also far less efficient than CaTs®, a Calcium Thiosulfate liquid fertilizer from Tessenderlo Kerley. And, in today’s drought conditions, these things matter. CaTs reduces the harmful effects of salts in the soil. Its calcium is 100% soluble, which makes it faster and more efficient at conditioning the soil and improving water percolation. Field studies in California’s Central Valley proved CaTs outperformed gypsum in tests of solubility, sodium displacement and increased availability of soil nutrients at an overall lower cost. Visit CropVitality.com/CaTs to learn more about the benefits of adding CaTs to your nutrient program. ©1993, 2015 Tessenderlo Kerley, Inc. All rights reserved.

PATHWAY TO PCA

Curriculum Development Project Shannon R. Douglass, Pathway to PCA Consultant

FFA Ag Pests Contest e are pleased to share photos of the State FFA Ag Pests contest winners. These individuals and teams have worked very hard to learn how to identify a variety of agricultural pests. In addition to ID, they must also learn how to pests work and be able to articulate that information orally in presentations to the contest judges. This year the winning team is a newly chartered FFA at a private school. This was the first State Championship win by a private school. Central Catholic High School in Modesto received their FFA in September of 2014. Each of the team members were brand new to FFA but had the support of a great ag teacher Mrs. Nicole Morris and an experienced coach Matthew Terra. There are less than 10 private schools with FFA programs in California. Bringing FFA into a private school is a very new opportunity and clearly these programs are excelling!

The winner of the High Individual award at the State Finals of the FFA Ag Pests contest was Mackenzie Winters of Tulelake High School. Congratulations to all of the winners in the 2015 Ag Pests contest! Doing What Matters In July we partnered with the Doing What Matters program at Shasta College and Vivayic curriculum company to bring 5 great California ag teachers together and create 5 new lesson plans promoting crops careers. The invited teachers included Janice Lohse from Hamilton High School, Jerry DelSol from Woodland High School, Tim Brown from Tulelake High School, Heather Thomas from Colusa High School and Lauren Stroud from Red Bluff High School. We began the two-day event with tours to showcase the diversity of career opportunities in crop science. We started at the Tremont Lyman Group in Woodland where Gary Silveira, Vice President of Sales and Marketing, gave us an overview of their business while we drove to meet a grower during tomato harvest. The teachers were able to watch harvest while learning about production from the farmer and PCAâ&#x20AC;&#x2122;s perspectives. From there we headed to the Inland Terminal to see the scale of

the fertilizer business in Northern California. After many teacher questions we took a quick lunch break before heading to Bayer. There we toured their new facility in West Sacramento. The teachers were very impressed with the high tech facility and had many questions for Kelly Oâ&#x20AC;&#x2122;Halloran (Communications Manager, Biologics at Bayer) as we wrapped up. We finished the day with a working dinner discussing the diversity of careers and abundance of opportunity for students. Day two began with looking at industry trends in retirement and growth. We then heard from Fred Strauss from Crop Production

Services about the PCA opportunity, what the career is like and steps for students to take if they are considering this career. After the presentations the teachers went into development mode, covering the walls in post it notes and ideas. It was really fascinating to watch them work and share ideas. By the end of the day the group had developed 5 lesson plans about careers in crop science. These lesson plans will be test piloted early this fall by Vivayic and adjusted as needed. They are all designed to meet the incoming curriculum standards and be easy for teachers to adopt. The lessons should be finalized and

ready for distribution by the end of 2015. We will host the lesson plans digitally on the Pathway website and be distributing them electronically to teachers across California. These will be great resources to share with your local high school programs. We are very pleased to be able to work with Doing What Matters on projects like this. We hope that these lesson plans will be used by many teachers across the state and help promote the many careers in crop science to encourage students to seek out the associated educational programs.

CAPCA ED: Expanding Seminar Topics to Increase Professional Training Opportunities by the CAPCA ED Coordinators: Lien Banh, Ariana Zamora, and Mindy DeRohan

APCA ED is continually working to create dynamic seminars and increase the continuing education opportunities that assist pest control professionals and crop consultants in improving their professional knowledge. Nutrient Management and Sustainable/Organic Seminars Nutrient management seminars offer hardcore nutrient topics that tie in with CCA and DPR continuing education units. Traditionally, CAPCA ED offers two nutrient management seminars annually. This year, the seminars were held July 28 and July 29 in Atascadero and Fresno. The feedback received from the seminars was very positive. Topics center around the benefits of liquid fertilizer, chemigation and fertigation, potash’s role in plant health, soil and tissue testing and analysis to identify nutrient deficiency, micronutrient managements, and benefits and uses of enhanced efficiency nitrogen fertilizers. CAPCA partners with the Organic Fertilizer Association of California (OFAC) and various local CAPCA chapters to offer five

Sustainable/Organic Seminars each year which feature a unique format with exhibitors. This provides attendees with an opportunity to network, make business connections and learn about new products while earning continuing education units. Sustainable/Organic Seminars incorporate a grower panel with local organic growers that specialize in specific aspects of the organic industry – this really adds to the attendee’s value of the industry being able to learn from these growers. These types of seminars have been very successful over the last eight years and the CAPCA ED team is constantly working to create programs that incorporate new technology and information for crop consultants and pest management professionals.

MINDY DeROHAN Nutrient Management Coordinator mindy@capca.com (916) 928-1625 x207

Field and Turf Days Field and turf days are another format that increase value in continuing education seminars. CAPCA ED is working to incorporate more field and turf days into the annual CAPCA schedule. In July, CAPCA ED teamed up with the SoCal STMA chapter to host a turf day at Poway High School. The feedback we received was very positive and showed that the turf day was a welcome addition to traditional continuing education seminars. Attendees listened to presentations on Common Violations by the San Diego Department of Agriculture, Weights and Measures, along with a mock inspection of a landscaping truck. Mike Tarantino of the Poway Unified School District made this day possible by providing the venue.

Photo, Left: Drip Irrigation, Fertigation and Chemigation of Turf and Shrub Areas by Netafim, Poway Turf Day. He also organized an exhibit station where various vendors displayed products and company information allowing attendees invaluable networking opportunities. There were also five stations that attendees cycled through. This successful format allowed attendees to hear from a variety of speakers and participate in a variety of demonstrations. Dr. Niamh Quinn, Area Vertebrate Pest Advisor, demonstrated effective methods of vertebrate pest control. Joe Schmitt from Target Specialty Products demonstrated spray equipment and calibration. Dr. James Baird of UC Riverside spoke on Best Management Practices for Turf Grass. Netafim, USA provided a demonstration of Drip Irrigation, Fertigation and Chemigation of Turf and Shrub Areas, courtesy of Bill Millward.

The final rotation focused on weed control and involved a pop quiz and prizes from Chris Bunnell and Crop Production Services. CAPCA ED and SoCal STMA are currently working on a date for the 2016 schedule, so stay tuned! Urban Nutrient Management Seminars In the past, CAPCA ED has primarily provided seminars with topics about pests and diseases. Mostly, how to identify and control pest and diseases using chemical control. Depending on the area, CAPCA ED seminars incorporate urban nutrients through agriculture or turf and ornamental topics. Law topics are included to ensure that attendees are able to fulfill the continuing education requirements. As CAPCA ED continues to grow,

the feedback from the evaluations shows attendees are looking for more urban nutrient topics. To address this, CAPCA ED has worked to incorporate liquid fertilizer education, composting, tree health and composition, turf health and management, and native plant selection for landscapes into meeting agendas. This is an area that will continue to grow in the coming year. T

Leaffooted Bug: What We Know and What We Need to Know Kris Tollerup, Area IPM Advisor for the San Joaquin Valley, UC Statewide IPM Program and Cooperative Extension, Kearney Agricultural Research and Extension Center

he leaffooted bug, Leptoglossus zonatus (Dallas), which occurs in the San Joaquin and Sacramento valleys, is native to the Americas. The species commonly occurs through the southwestern United States, particularly in California, Arizona, and Texas (Allen 1969). Although in California L. zonatus is most familiar as a pest on almond, pistachio, and pomegranate, it has a wide host range including several commercial citrus cultivars, cotton, corn, dates, eggplant, passion fruit, peaches, sorghum, tomato and watermelon (Albrigo et al. 1977). Adult and nymph leaffooted bugs typically feed on seeds. However, they can feed on stems of woody and herbaceous plants. On almond and pistachio, the later instars and adults have the greatest potential for causing damage due to stronger piercing mouthparts that enables them to penetrate through a developing shell to reach the nut meat. Early-season feeding damage on almond and pistachio cause nuts to abort while later-season damage causes necrotic lesions on the shell and nut meat (Daane et al. 2008). In addition to direct feeding damage, L. zonatus can also vector the yeast pathogen Nematocera coryli Peglion that causes heart rot disease on pomegranate (Henne et al. 2003). Leaffooted bug overwinters on host plants as well as sheltered areas such as pump house structures. In the San Joaquin Valley, the species commonly overwinters in aggregations on citrus, pomegranate, cyprus, and palm trees. Aggregations begin forming in the fall and vary from 5 to 500 individuals. Although the occurrence of warm temperatures in late winter causes a small number of individuals to disperse from aggregations, the majority disperse during spring. Movement into almond tends to take place from the end of April through May and into pistachio during May through July. In California L. zonatus generally has three to three and a half overlapping generations per season. The longevity of adults is approximately 50 days and females can produce an average of 335 eggs over their life span. L. zonatus has 5 instars and takes, depending on temperature, approximately 42 days to go from egg to adult (Jackson et al. 1995). The University of California (UC) has developed leaffooted bug sampling recommendations. However, to improve upon the recommendations, we must better understand its biology. Current UC IPM recommendations for sampling almond early in the season, for example, include examining aborted nuts for gummosis, or oozing on the nut surface. The drawback is that leaffooted bugs can enter and leave an orchard relatively quickly and by the time a grower or PCA identifies the damage, the

leaffooted bugs have likely moved on. Other sampling methods include using beat trays or a long pole to knock upper-canopy branches to startle adults. Beat trays are useful for monitoring nymphs but not for adults since the adult insects generally startle and fly away prior to the being knocked onto the beat tray. Kent Daane, UC Cooperative Extension specialist, has conducted extensive research on leaffooted bug during the early 2000s. He, along with Wang et al. (2000), determined that a pheromone plays a key role in cuing the species to aggregate. Unfortunately they could not identify the precise compound. Once a compound is identified itâ&#x20AC;&#x2122;s possible that the pheromone can be produced synthetically, placed into a dispenser and used as a monitoring lure. Other possible lures may exploit plant volatiles. Experiments currently in progress have looked at various oils, such as avocado, peanut, and walnut. To date, the most attractive material tested consists of whole ground pistachios. The ground pistachios placed in a mesh bag

attract nymphs (Fig. 1); itâ&#x20AC;&#x2122;s not clear though if a female haphazardly lays eggs near the bag then the nymphs move onto the pistachios to feed or if the female detects a suitable host

food, and lays eggs near the bag. The latter scenario certainly holds the most promise; if a lure can be developed that attracts females, then early-season movement into orchards could be detected. The ability to forecast leaffooted bug pressure based upon winter temperatures could help producers of susceptible crops plan management tactics for the spring. Research that we conducted in 2014 showed that cold winter temperatures have a considerable adverse effect on overwintering populations of L. zonatus (Fig. 2). Also, Daane et al. (2007) looked at field populations of Leptoglossus clypealis (Heidemann) on citrus and found similar results to ours, that temperatures below approximately 27Â°F substantially decreased overwintering survival. Presently, no insecticide chemistries other than pyrethroids provide sufficient residual activity to protect almond and pistachio. We conducted field experiments in which we bagged adults on pistachio clusters at 1, 7, 14, 21, and 28 days after treatment (Table 1). In our experiment, only bifenthrin performed well.

Interestingly, the reducedrisk compounds clothianidin, tolfenpyrad and cyantraniliprole showed excellent activity when the compound was applied directly on the bugs (Table 1). Tolfenpyrad and cyantraniliprole do not have a California registration on almond. Leaffooted bug can cause serious economic loss on several crops produced in the San Joaquin and Sacramento valleys. The crops most commonly affected by L. zonatus include almond, pistachio, and pomegranate. We do not know if this species will become a more common pest of other commercial host crops. To improve IPM of L. zonatus, we must continue making progress toward understanding its biology and pheromone communication. T

Efficacy of Novel Insecticides in Managing Lygus Bugs in Strawberry

Shimat V. Joseph, IPM Advisor, UCCE, Salinas, CA Mark Bolda, Strawberries and Caneberries Farm Advisor, UCCE, Watsonville, CA Hillary Q. Thomas, Senior Research Manager, California Strawberry Commission, Watsonville, CA

ygus bug (Lygus hesperus), is a serious pest of strawberry in the Central Coast of California. Adult and nymphs feeding on the tissue around the seeds of developing young strawberry fruit results in misshapen, “cat-faced” fruits after fruit expansion (Figure 1A) rendering it unmarketable. This damage can be very widespread in the field, and cases of 100% fruit loss to this pest are not unknown. In normal situations, fruit loss to lygus bug damage can still be more than 10% of the total crop.

Life cycle: The life cycle of the lygus bug consist of three distinct stages – egg, nymphs and adult. Female lygus bug pushes eggs singly into the plant tissue with only the egg cap projecting out (Figure 1B). The eggs hatch within a week, although hatching rates vary by temperature. The nymphal stage (Figure 1C) consists of five instars which generally lasts for about two weeks. The last nymphal stage molt into adult lygus bug (Figure 1D). The newly developed females begin laying eggs

about 10 days after reaching maturity. On average, a female lygus bug lays 32 eggs per day and a maximum of 448 eggs for life time have been documented. Adults generally survive for 35 to 43 days. Challenges of managing lygus bug in strawberry: As a native insect to California, lygus bug has been a pest in strawberry for a very long time and continues to be one because it is accustomed to the environment around strawberry fields and has evolved to do well with

the growing native plants outside of fields. Strawberries become attractive in the summertime when the surrounding vegetation becomes dry and unpalatable to lygus bugs, causing movement from these unmanaged areas into strawberry fields. Additionally, strawberries are sensitive to the activities of lygus bugs and have a low threshold for damage. Finally, having such a long history in strawberries means that lygus bug has been confronted with every registered insecticide and subsequently populations may have developed substantial levels of resistance to insecticides. With the above issues of damage and difficulty of control in mind, it is clear that insecticide screens, along with other avenues of scientific

study such as monitoring, cultural management and biological control need to be at the forefront of pest management research in strawberry. Insecticide efficacy trials: Insecticide efficacy trials were conducted in 2012 and 2014 including registered and unregistered insecticides for control of lygus bug in strawberry. 2012 insecticide trials: Three trials were conducted in 2012. In the first trial in Salinas, insecticides were applied on May 3 using a motorized backpack sprayer in a second year strawberry field. In the second trial in Guadalupe, insecticides were applied on Aug 28 and Sept 12 using a tractor mounted spray rig in first year strawberry field. The third trial was conducted in Watsonville using

a tractor mounted spray rig on Oct 5 and Oct 12 in the first year strawberry field. The insecticide rates and water volume used are listed in Table 1. Lygus bugs were sampled by beating 20 strawberry plants (3 times per plant) in a row into an open plastic container and counting separately lygus bug small nymphs (first and second instars), large nymphs (third, fourth and fifth instars) and adults. Lygus bugs were sampled weekly for 6 weeks following the first spray application in Guadalupe, weekly for three weeks following the first application in Watsonville and weekly for four weeks following the first application in Salinas. Fruit sampling consisted of randomly picking 50 fruits from the center two beds of each trial. These fruits were graded

Fourteen days after application, the data show that sulfoxaflor, tolfenpyrad, and malathion treated plots in the Salinas trial had lower numbers of large lygus bugs than in the untreated control (Figure 2A). In Guadalupe, numbers of both small and large nymphs and adults were significantly lower in the sulfoxaflor treated plots than tolfenpyrad and untreated check treatments (Figure 2B). In Watsonville trial, numbers of small nymphs were lower in the sulfoxaflor treated plots than tolfenpyrad and untreated check treatments, whereas numbers of larger nymphs were significantly lower in sulfoxaflor, and tolfenpyrad than untreated check (Figure 2C). Overall, numbers of both small nymphs and adults were significantly lower in the sulfoxaflor treated plots than tolfenpyrad and untreated check treatment in Guadalupe trial (Figure 3A) whereas, only numbers of small nymphs were lower in sulfoxaflor treatment than the other two treatments in Watsonville (Figure 3B).

Protect Roots from Nematodes and Replant Problem NEMATODES AND THE REPLANT PROBLEM

July 2013 – 2.5 years after planting

The replant problem is the unfortunate result of planting trees and vines into soils plagued with nematodes and soil-borne diseases. Tree nuts/fruits planted after tree nuts/fruits may experience this problem. Even grapes planted after tree nuts/fruits experience the problem. Orchards and vineyards suffering from the replant problem show poor growth and poor vigor, often for the entire life of the crop. As root and vegetative growth suffers, so do yields.

Untreated

Telone® II – broadcast

The replant problem is caused by nematodes and a complex of soil diseases, not all of which are known. Using rootstock with nematode and/or disease resistance will not completely stop the problem as no single rootstock is resistant to all species of nematodes and pathogens.

WHY FUMIGATION IS IMPORTANT

University of California, USDA-ARS trial. Merced County.

May 2013 – 5 years after planting Fumigated Untreated

The components of the replant problem – nematodes and pathogenic soil organisms – are found throughout the soil profile and several feet deep, making them very difficult to reach with most crop protection products. Telone® soil fumigant is injected 18" deep into the soil as a liquid and quickly converts to a gas. The vapors move through soil pores and eventually dissolve into the soil moisture. That movement through the soil is fundamental and essential to the effectiveness of fumigation for pest control. Telone does more than just kill old roots and manage nematodes and soil-borne pathogens; it creates a zone of protection around roots, allowing them to grow better, stronger and faster. The ultimate result: extensive, healthy root systems capable of producing high-yielding, high-quality crops. The increased growth provided by soil fumigation (compared to untreated) is so dramatic that the cost of fumigation is often paid for with the first crop harvested.

Twenty strawberry plants were sampled and the sampling consists of five strikes per plant with the lid of a regular sized RubbermaidÂŽ container. Sampling was done a day before application, then at 2 or 3, 7, and 14 days after each application. The samples were evaluated for all nymphal stages and adult of lygus bug. In addition, 40 fruits were randomly sampled from each plot at 21-days after second insecticide application. Fruit evaluation was conducted in the same manner as in 2012. Similar to 2012, only lygus bug data 14 days after application and overall bug capture are presented. Precount of lygus bug nymphs was similar in all plots. Fourteen days after the first application, the number of lygus nymphs was significantly lower in the sulfoxaflor treatment than fatty acid treatment (Table 2). The number of adult lygus bugs captured was similar in all treatments when all sample dates were combined. The numbers of large nymphs were significantly lower in thiamethoxam + fenpropathrin and sulfoxaflor treatments than other treatments (Figure 5). The number of adults was numerically lower in the sulfoxaflor treatment compared with other treatments. Based on fruit evaluation, number of fruit with catfacing injury was no difference among treatments; therefore, not presented. Overall, sulfoxaflor and thiamethoxam + fenpropathrin treatments showed evidence of lygus bug suppression in 2014 study. Conclusion: These studies show that both sulfoxaflor and tolfenpyrad can suppress lygus bug nymphs in the field conditions. Although these new insecticides are not currently registered on strawberry in California, sulfoxaflor is under consideration for registration on strawberry with California Department of Pesticide Regulation. Clearly, these products, if registered would be valuable additional tools in combating lygus bug in Central Coast strawberry production. T

AfriKelp is high in naturally occurring “Natural Growth Elements”. When applied to the plant leaves, it is easily assimilated into the leaves and transported cell to cell in a basal direction down to the roots and increases the growth of adventitious root hairs. The more adventitious roots there are, the higher the uptake of nutrients and water. The tips of these new roots produce other natural growth elements which are transported through the xylem and initiate corresponding shoot growth. This process takes 7 to 10 days and produces a stronger, healthier plant that can take up more available nutrients and defend itself better against biotic and abiotic stress factors. The end result is higher yield and better quality crops.

Root Aphids and their Management in Organic Celery Surendra K. Dara, Strawberry and Vegetable Crops Advisor and Affiliated IPM Advisor, University of California Cooperative Extension, San Luis Obispo, Santa Barbara, and Ventura Counties

few species of aphids infest celery in California. According to the UC IPM Pest Management Guidelines, the black bean aphid (Aphis fabae), the foxglove aphid (Aulacorthum solani), the green peach aphid (Myzus persicae), the hawthorn or parsley aphid (Dysaphis apiifolia), and the cotton or melon aphid (Aphis gossypii) attack celery and cause varying levels of damage. These aphids feed on the aboveground plant parts – leaflets and petioles – and some of them are vectors of virus diseases such as western celery mosaic, celery calico, cucumber mosaic, celery yellow spot and others. In late 2014, an organic celery field in Santa Maria was severely infested with aphids feeding on the

root system. Aphid feeding damaged the root system, stunted the plant growth or resulted in the death of the plants. Yield loss was estimated to be up to 80% based on grower’s feedback. Gillian Watson at CDFA identified the aphid specimens as the rice root aphid, Rhopalosiphum rufiabdominale (Sasaki) and the honeysuckle aphid, Hyadaphis foeniculi (Passerini). While there was only one earlier record of the honeysuckle aphid infestation on celery, according to the CDFA records, the rice root aphid has never been reported on celery. This is the first record of the rice root aphid on celery. Multiple species of the genus Hyadaphis are referred to as honeysuckle aphid, coriander aphid,

and others in the literature, but the one identified on celery was H. foeniculi. The rice root aphid is known to infest graminaceous (barley, rice, and wheat), rosaceous (apricot and plum), and solanaceous (potato and tomato) crops and is known to vector the barley yellow dwarf virus of grasses and small grains. The honeysuckle aphid is known to be an important pest of apiaceous (fennel), caprofoliaceaeous (honeysuckles), and lamiaceous (mints) plants and involved in the transmission of 13 viruses. Depending on the host plant they are feeding on, the wingless form of the rice root aphid can be olive to dark green or brownish with

To address the issue, a field study was conducted using the following organically approved treatments: i) untreated control, ii) blend of rosemary oil 10% and peppermint oil 2% at 19.2 fl oz along with 12 fl oz of silicone and nonionic surfactants, iii) azadirachtin 3% at 6.3 fl oz along with 20 fl oz of alcohol ethoxylate, iv) Beauveria bassiana at 1.5 qrt, v) B. bassiana at 1.5 qrt along with azadirachtin at 6.3 fl oz, vi) Burkholderia spp. at 2 gal, and vii) Chromobacterium subtsugae at 2 lb per acre. Each treatment was about 0.3 acres of a single plot and pesticides were administered through the drip system at 250 gpa rate for 4045 min on December 9 and 23, 2014. Aphid infestations were evaluated on December 6 (pre-treatment), December 22 (13 days after the first treatment), and January 2, 2015 (10 days after the second treatment). On each sampling date, 10 plants were pulled out from random locations within each treatment, roots were washed in mild soap water, and aphids floating on the surface were filtered and counted. Numbers for each species of aphids were not recorded separately. Data were subjected to analysis of variance and significant means were separated using Tukeyâ&#x20AC;&#x2122;s HSD test. Results: There was a significant difference in aphid numbers among different treatments before and after each application (P < 0.002) and when the average for both applications (P < 0.0001) was considered.

overall change in aphid populations after both applications compared to the pre-treatment numbers was considered, there was a 3% reduction in untreated control, 24, 18, and 129% increase in rosemary+peppermint oil blend, azadirachtin alone, and B. bassiana alone treatments, respectively. However, B. bassiana and azadirachtin combination provided a 62% reduction in aphid populations followed by a 29% reduction by C. subtsugae and 24% by Burkholderia spp. This study demonstrates the potential of non-chemical options in managing aphid populations in organic celery. Microbial pesticides, especially in combination with botanical pesticides, can play a significant role in pest management. Understanding the modes of actions of different options and using the right combinations is critical in pest management decisions. B. bassiana and azadirachtin combination also played a significant role in IPM studies for managing lygus bug in strawberries.

PCA PROFILE

Central Valley PCA Aaron Heinrich:

Hardworking & Motivated to Lead

by Joyce A. Basan, CAPCA Programs/Communications Director

aron Heinrich has been active in the agricultural industry for 18 years. Specializing in nutrient management, the major crops he consults on are corn, alfalfa, almonds and walnut. Besides being a PCA, he also holds a QAL and CCA certification. Aaron attended Modesto Junior College, Delta College, and is a graduate of the California Agricultural Leadership Program. After working for Stanislaus Farm Supply and Crop Production Services, Aaron started his own independent consulting business in 2013 called Agronomic Systems. When describing his consulting business, Aaron says “We help growers manage their fertility programs by providing them with nutrient management recommendations. We also closely monitor their crops for beneficial insects along with pest thresholds. Some of the key tools we use in determining treatment timing are trap data, weather and degree days. We also provide full service product support. We work very closely with seed companies keeping up with the latest traits and technology, ensuring our clients get the best possible seed selection fit for their particular farming operation.” The drought is a big concern for his clients: “California is experiencing the worst drought in its recorded history. This has forced growers to follow very strategic irrigation management to match water availability with critical crop growth stages,” he explains. “In many cases, land has been left fallow where water could be transferred to higher production potential areas. In other cases, we have had to change cropping programs, such as planting sorghum instead of corn using half as much water.” Changes in pest populations and infestations are also of concern: “Whether it’s an invasive pest such as the Asian citrus psyllid or Botryosphaeria in walnuts there is no doubt our pest challenges will continue well into the future. “I spend hundreds of hours monitoring everything about these crops, ensuring their greatest potential success. When harvest comes, it gives us a change of pace and a chance to reflect upon the year. This gives us an opportunity to make changes or adjustments to our cropping programs and ensure greater success in the following years. “There are so many things I love about being a PCA; it’s hard to narrow it down to just a

few,” says Aaron. “Probably the greatest is the people I get to work with each day. I have some of the best clients, with whom I very much enjoy working. I also enjoy working outdoors. I get to work with a diversity of crops, people and circumstances and each one poses its own set of challenges and rewards.” When asked what inspired him to choose the PCA profession, Aaron says “My father spent his entire career as a PCA and I was able to see firsthand the rewards and happiness his career brought him.” He finds that his decisionmaking in the field is influenced by a variety of circumstances: “I work with a diversity of clients and I have been very successful in matching crop recommendations to their unique farming operations and potentials. Throughout the growing season, I have the opportunity to educate my clients, helping them get to the next level,” says Aaron. The relationship between Aaron and his clients is very cooperative and includes a two-way exchange of ideas. “I believe successful farming in California today takes a team, which I am proud to be a vital part of. When a decision needs to be made, we come together, review our notes and findings, look at all our options and make that decision together,” says Aaron. “Educating clients is one of my favorite parts of the job. It is extremely important that growers know and understand why we do what we do. Growers bring a diversity of experience, knowledge and education to the field. It is my job to help

fill in the gaps and offer advice where it is needed. There is much controversy and confusion in the general public regarding food safety concerns. I believe it is the duty of every agriculturalist to take part in the education process. The agricultural industry is changing rapidly as our food production increases with demand and I believe it is part of our job to keep the general public informed as to the processes involved in order to maintain this food quality and safety.” He encourages all PCAs to take advantage of the educational resources available to today’s crop and pest management professionals: “We are fortunate to have a University Cooperative Extension that has been great in providing research and results to local PCAs. Many offices send out their findings through monthly newsletters and meetings. Stanislaus County Cooperative Extension has, for some time, been conducting IPM breakfast meetings. These meeting are a great opportunity for PCAs to come together with growers and University Extension Farm Advisors to discuss current and local activities that are taking place in the field,” says Aaron. He also believes in the importance of continuing to advance his own knowledge, professionalism and participation in the crop production industry. “I invest large parts of my time to develop and mature my leadership skills in order to give back to an industry that has given so much to my family and me for generations. I am always looking for opportunities to learn and grow as a professional. I am a

graduate of the California Agriculture Leadership Program and currently serve as Vice Chairman of the Board for the CA Certified Crop Advisers.” Aaron serves on the CA CCA Marketing Committee and, starting in 2016, Aaron will assume the role of chairman on the CCA Board. When he finds he needs to seek other resources and expertise, Aaron turns to the education and networking provided by CAPCA: “By attending many meetings put together by CAPCA, I have been able meet so many well-educated and experienced people, many of whom I’ve been able to call on when I’ve had a need or a question.” Aaron has been very supportive of CAPCA because of the support he sees CAPCA providing to the PCAs. “I believe CAPCA has done an excellent job in supporting our industry. They have been at the forefront of challenges that Pest Control Advisors deal with, sometimes on a daily basis,” he reflects. “CAPCA has done a great job of keeping the industry informed of developing regulatory issues through the Adviser magazine, annual meeting and CAPCA ED seminars. This has given the PCA a great advantage and opportunity to continue their learning through a variety of sources, gaining CEUs and networking.” T

enjoyed serving as a representative on Rice and Specialty Crop Committees for Farm Bureau, as well as on the Butte County Young Farmers and Ranchers board. John wrote in his application that “Farm Bureau has provided me with a great experience in learning about governmental impacts on agriculture and the need for public education on many agricultural issues, as well as giving me extraordinary networking opportunities locally and at the state level.” We received the following letter from John: “I am honored to be a recipient of the 2015 CAPCA/ Stanley W. Strew Scholarship. My love for agriculture began as a boy growing up on my family’s almond orchard in Chico, CA. After returning home from serving four years in the Marine Corps, there was no question that I wanted to pursue a career working in agriculture. During my freshman year at California State University, Chico, a class interview with a Pest Control Adviser from North Valley Ag Services sparked my desire to learn more about agricultural science and pursue my own PCA license. While attending Chico State, I have had the opportunity to intern at Gorrill Ranch Enterprises where I have gained an immense amount of knowledge in the production of rice, prunes, almonds, walnuts and pecans, key crops in the Northern Sacramento Valley. “Thanks to your generous support, I am able to continue my education as CSU, Chico. I look forward to finishing my last year of college and embarking on a career as an agricultural adviser. Your scholarship has undoubtedly eased my financial burden and will allow me to focus more time on my studies and to finish school strong. I appreciate the privilege to further my education. Thank you so much for your support.” T

Optimum Ca Management Reduces Drought Stress

Four Rs

One important tool that can increase WUE is optimum nutrient management using the Four Rs of nutrient stewardship: the Right rate, applied using the Right source, at the Right time, in the Right place. Optimum nutrient management increases crop yield and quality while minimizing the potential for adverse environmental effects.

Soil physical conditions

PCAs have reported more issues with surface crusting this year than ever before. The drought has increased levels of salts in many irrigation water sources. In addition, reduced winter rainfall means less sodium (Na) leaching leading to surface crusting and sealing that reduces water infiltration. The solution is to apply soluble calcium (Ca), the ‘glue’ that promotes good soil structure, when coupled with good irrigation management.

Salt and water availability

Salt in the soil reduces water availability to crops and induces water stress in crops. Increasing the concentration of soluble Ca helps the crops maintain adequate cell water uptake in the presence of salt stress (Fig. 1).

Ca and cellular response to drought

Calcium is essential for cell wall and cell membrane structure and integrity and plays a key role in many cellular processes that help plants deal with drought stress. Oxygenated radical compounds, such as H2O2 (hydrogen peroxide), are formed during photosynthesis. During drought stress, they can accumulate and damage the plasma membrane, causing water and

nutrient leakage from cells. To control these radical compounds, the plant releases mobile Ca stored in vacuoles to stabilize and maintain plasma membrane integrity. Salinity reduces chlorophyll formation which reduces photosynthesis, the engine that drives crop yield. Adding supplemental Ca overcame the adverse effects of the salinity on chlorophyll formation in tomatoes. (Fig. 2). Leaf chlorophyll (Spad units)

If the forecasters are correct, the coming winter may herald the end of the worst drought since we began farming in California. Even after this terrible drought has broken, our soils and crops will continue to feel its impact because of reduced surface and ground water quality, and increased salinity. Increased urbanization and greater competition for limited water resources will also challenge California agriculture. Growers have made great strides but we must continue to improve water use efficiency (WUE) using all the tools available to us.

Salinity stress

A vigorously growing root system will help assure that the plant takes up all the available water in the soil and soluble Ca promotes healthy roots, robust root elongation, and more prolific root hair development. Stomates are leaf structures through which water is lost and CO2 is taken into the plant. Stomates account for 90 to 95% of the transpirational water that is lost by plants. Proper functioning of the stomates is essential for plants to take up CO2 and to limit water loss during periods of water stress. Calcium, along with its partner cation, potassium, is essential for proper functioning of the guard cells that open and close the stomates.

Soluble Calcium

The preferred source for soluble Ca for improved soil physical conditions and plant nutrition is YaraLiva Calcium Nitrate. YaraLiva® Calcium Nitrate is available in liquid form as YaraLiva® CN-9® and CN-8 and in dry form as YaraLiva® Tropicote® for general use; YaraLiva® Calcinit® is for use in greenhouse and hydroponic production systems.

Summary

Optimum Ca management is a critical part of getting the most value from each precious drop of water. Adequate Ca in the soil helps assure good soil physical conditions and adequate Ca in the crop helps the plant overcome the adverse effects of excess salinity and maintain good growth and high yields.

Newly Approved Biofungicide Prevents Botrytis Infection

Botector® has proven efficacy in more than four years of research and commercial trials under a variety of growing conditions. Botector® is exempt from Maximum Residue Limits (MRL’s), so there is no PreHarvest Interval (PHI), making it an ideal product to use when pesticide residues are a concern. Botector® must be applied prior 60 to onset of the pathogen infection as a preventative because it has no60direct toxicity to the 50 pathogenic organisms. A. pullulans does not produce antibiotics 50 or toxins as its mode 40 of action is competitive exclusion. The Botector® active ingredient outgrows the 40 pathogen, robbing it of essential 30 nutrients and space for growth. Because A. pullulans has evolved on the30 surface of plants, it will 20 survive through irrigation or rain events. In fact, University studies 20 have confirmed that

the organism is a fastidious member of the natural orchard microfloral. It is also safe for bees and beneficial insects. Botector® application timings are optimized to protect the plant at its most vulnerable physiological stages. It’s important to apply Botector® prior to weather conditions (i.e. a rain event) that are favorable for the onset of the disease. If a weather model is available for the crop in question, it is recommended that applications be fine-tuned accordingly. For many crops the application timings are discreet times during the growing season and one example is the late bloom window in grapes, when petal scars can serve as a site for infection by Botrytis cinerea. Postveraison in grapes is another window for grape applications since the elevating brix and late season fruit splitting can serve as a food source for the pathogen. Similarly, blossom blight and brown rot have their primary infection periods during bloom, so applications through the bloom window on stone fruit are recommended for the control of those diseases. For crops which are continuously harvested, applications of Botector should be made as long as the weather indicates disease pressure. It is also important to continuously treat crops such as berries that have newly emerging susceptible plant tissue. As with all contact pesticides, good coverage is critical.

Botector® is an excellent tool for IPM because when used in rotation with other chemicals it reduces the potential for resistance to develop.

In addition, it is labeled for the control of anthracnose, phomopsis, and rhizopus rots of berries. The active ingredient in Botector® consists of two strains of Aureobasidium pullulans, a yeast-like fungus that is commonly found on the surface of fruit and flowers.
