CAPCA EDITORIAL STAFF Ruthann Anderson - Editor Joyce Basan - Deputy Editor Dee Strowbridge - Membership/Conference Sylvia Stark - Advertising Sales Manager Lien Banh - Office Manager Mindy DeRohan - CAPCA ED Manager Ariana Zamora - So. CA Representative Jacqueline Tabarez - No. CA Representative Rachel Kihlthau - Executive Assistant Graphic Design - Rosemary N. Southward southwardr@comcast.net MISSION & PURPOSE California Association of Pest Control Advisers (CAPCA) is a non-profit voluntary mutual benefit association that represents 75% of the 4,000 California EPA licensed pest control advisers. CAPCA’s purpose is to serve as the leader in the evolution of the pest management industry through the communication of reliable information. CAPCA is dedicated to the professional development and enhancement of our members’ education and stewardship which includes legislative, regulatory, continuing education and public outreach activities.

ast year, our demographic membership survey projected that close to 1,000 PCAs would be retiring over the next five years. A year later, we are still losing licensees faster than we can educate, train and equip new PCAs. As an industry, we must address this trend. The great legacy that has been built by 42 years of association work is now being passed to the next generation. CAPCA members with a range of experience are responsible to successfully facilitate the transition of leadership and a pathway to becoming a career PCA. Leadership within Chapters, influencers in the community and innovative industry leaders alike impact this bottom line. We must work together to move students along on a Pathway to PCA and equip new PCAs with the ability to fill the boots of retirees. CAPCA is piloting the Pathway to PCA Student Networking Event at our Annual Conference and the Leadership Institute Connect for new PCAs. Both of these programs are the first step towards this transition of leadership. We need legacy members poised to mentor new PCAs, Chapter Leaders writing succession plans to equip the next generation of volunteers and speakers who are willing to share their career story in hopes that those coming behind them will learn from the strong history of this professional license. As CAPCA continues to develop programming, I am asking you to be part of building CAPCA’s future as a legacy volunteer or through a contribution to the Stanley W. Strew Education 501 (c) 3 Trust (see donation form on page 56). Ruthann Anderson, Editor ruthann@capca.com

onference will be here before we know it. Feeding a Nation – Fighting the Fear is a great theme. It should be an excellent opportunity to network and create solutions for CAPCA to move forward. When we hear that lawmakers and regulators are working on buffer zone regulations that would prevent pesticide use within one mile of a school, you know we are facing real challenges. Pest Control Advisers (PCAs) play a critical role in feeding our nation and the world. However, public perception is beginning to adversely impact our profession. Being an urban PCA and arborist, I read letters to the editor in local newspapers protesting vector control. It seems a segment of our population prefers a risk of West Nile Virus infection over the use of an insecticide fogging exposure. There is virtually no worry of mosquito-borne illness anywhere yet there is an irrational, emotional backed fear of any pesticide use. This is becoming our experience. Our company started spraying trees in 1911. Over the last 23 years I have watched perceptions change, I am told that IPM means no spraying. Some people are fine with soil treatments, trunk injections and bark treatments. The net result is a significant reduction in Plant Health Care services over the last five to ten years. The even more bizarre coincidence is the number of dead or declining trees we have removed in that time. Suburban cultural practices around trees are poor and reducing disease and pest management practices doesn’t seem to help. CAPCA has 16 chapters across the state of California. Our recently approved rebranding project is moving forward. Our Public Relations Committee, chaired by Paul Crout and Leanne Becker, will be working with our rebranding contractor to

John McClenahan CAPCA Chair john@spmcclenahan.com spread positive messaging about what PCAs do. CAPCA Forward is the committee that pushed this project. We have several other committees needing volunteers. Government Relations, Continuing Education and Conference. Everyone is busy, we all work long hours, but I can assure you the benefits to you as a volunteer exceed the time you put in. Losing Terry Stark to retirement challenged our staff in the CAPCA office and during some difficult times in the transition CAPCA staff held our organization together. Our Executive Committee, Search Committee and Board of Directors also pushed us forward through this transition. Everyone’s effort the last two years is greatly appreciated. CAPCA announced at the recent board meeting on August 18, 2016 the newly elected officers for the years 2017 - 2018. Chair is Rick Wescott, Vice Chair is Rick Harrison, Treasurer is Gerald Martin and Secretary is Leanne Becker. Congratulations to the new Executive Committee! Now let’s go move CAPCA FORWARD. T

The California Department of Pesticide Regulation has announced the appointment of the new Chief Deputy Director. TERESA MARKS, who stepped into the role on July 18, 2016, comes from Little Rock, Arkansas and was appointed by Governor Jerry Brown. Marks already has a strong awareness of challenging environmental issues, as prior to her appointment she was the principal advisor to the administrator for unconventional oil and gas at the U.S. Environmental Protection Agency in Washington DC (from 2015 to 2016) and director at the Arkansas Department of Environmental Quality from 2007 to 2014. She also held several positions in the Arkansas Attorney General’s Office including deputy attorney general in the Public Protection Department.

PCA PROFILE

Corey Thompson:

Building Relationships in the Pest Control Industry by Mindy DeRohan, CAPCA ED Manager

orey Thompson grew-up in Northern California and received his Associate Degree at Shasta College. He then graduated from Chico State in 2003 with a degree in Agriculture Science and proceeded to earn his agriculture teaching credential. Corey has been involved in the pest management industry for 11 years. For the past eight years he has worked for Basin Fertilizer and Chemical Company. Prior to working for Basin Fertilizer, Corey worked for the UC Cooperative Extension as a staff research assistant. It was Corey’s experiences with the cooperative extension that motivated him to become a PCA. “While working at the UC Cooperative Extension, I was given the task of organizing off-site grower trials which led to larger trails and eventually a PCA career.” In this current role, Corey oversees an area on the east side of the Klamath Basin all the way to Valley Falls, Oregon through Lakeview and down to Cedarville and Alturas, California. He inherited this area from James Baird, a salesman for more than 20 years. Basin Fertilizer and Chemical Company is a full-service company dealing in crop, pest, and agronomic consulting, fertilizer, chemical sales application, irrigation water management and GPS guidance systems. Corey represents more than 380 customers throughout his territory and specializes in alfalfa and cool season grasses. “Being outside and working with growers on a daily basis is my favorite part of being a PCA,” Corey said. “I’m a people person and I love the problem solving aspect of the job. Being able to disseminate a water or soil sample and look at the grower’s situation and trying to guide them in the direction that benefits them as well as the crop and seeing out how things work out is a great joy.” When asked about his most challenging pest management experience, Corey said it is working with specific issues of the grower and trying to match a solution that benefits them the most. “Canada thistle seems to be one of our hardest weeds and as long as we are in a pasture setting things generally work out, but when it is in alfalfa or other broadleaf forage, it gets very tricky,” Corey said. Corey believes that chemical resistance on all levels from insecticides and herbicides will be the biggest concern for the industry. “I don’t believe that one pest can have a broad reach on the industry, especially in the diverse state of California. Region by region, yes, we all have our certain pests, but the issue of resistance to pests should be of concern to all PCAs.” The experience that Corey has gained throughout the years as a PCA, along with the contacts that he has made in the industry, are what motivates him to make

“I want to try to get ideas from other members throughout the state to boost membership and gain local support and awareness.”

decisions for his clients. “Working for a small familyowned business that is not solely focused on sales gives us the opportunity to bounce ideas around and work together,” Corey said. Corey said that he works to educate his clients and growers on a daily basis. “Being a younger PCA, many of my clients have been in this game a lot longer - they teach me as much as I teach them.” Corey works to advise his clients on the best options available, but ultimately, it is his customer who makes the pest management decisions. When asked about a specific pest management problem, the challenges and how it was resolved, Corey said they had a big problem in the spring of 2015 with the blue alfalfa aphid. “The pest has shown resistance to the conventional treatment methods and we were seeing significant infestations and yield loss due to the pest. We worked with local agricultural commissioners and Farm Advisors along with PCAs on different ways to deal with

this new pest. A new chemical was released that we set up test plots with that also included alternative and conventional treatment methods. We worked diligently and were able to eventually control the blue alfalfa aphid.”

CAPCA ADVISER | OCTOBER 2016

Just like with the blue alfalfa aphid example, Corey turns to the other PCAs and the Cooperative Extension for areas that he does not have expertise. “CAPCA’s networking has given me opportunities to meet a variety of representatives from a myriad of pest control companies as well as other PCAs with whom I have built relationships and am comfortable calling on with questions or for advice,” Corey said. The biggest highlight of his career has been being trusted and valued as a PCA and this comes with the relationships he has built. When asked to describe IPM, Corey said that IPM is just part of the job. “The nuclear option is never the first option. We pride ourselves in religious field scouting and keeping in touch with our growers. When pests are identified all treatment options are reviewed and vetted before a chemical recommendation is made.” In Corey’s region, they are using more and more Roundup Ready alfalfa. This new technology has become a great tool for the TriCounties area with lack of rotational crops or alternatives to a forage grain rotation. “With some special weed situations, the rotation with Roundup Ready alfalfa allows us to address the weeds during the alfalfa cycle and

keep the grains as clean as possible,” Corey said. When asked what the most challenging part of trying to educate his growers and the public is, Corey said, “it is getting to know your grower on a level that lets you talk to them and share ideas about new ideas and technologies. Educating the public can sometimes be a little bit frustrating because of the disconnect that the public has with where their food comes from. From time to time, you have to take a step back and try to put yourself in their shoes.” To improve his own professionalism, Corey tries to attend different grower/industry meetings during the off-season to learn about different management techniques to share with his growers and clients. One of Corey’s goals has been to grow the Tri County CAPCA Chapter. “I want to try to get ideas from other members throughout the state to boost membership and gain local support and awareness,” Corey said. Besides serving on the CAPCA Board for his chapter, Corey serves on the Board of Directors for the Klamath County Soil and Water Conservation District and the local California Deer Association Committee. In addition to his PCA license, Corey also holds a CCA certificate and an Oregon Consulting License. T

Nutrient Management & Efficiency Technologies

keeping it more readily available for the plant to use. And farmers are seeing the results.” AVAIL can also help ease environmental concerns. When crops are able to use more of the phosphorus available to them by adding AVAIL, less is moved off-site and into water ecosystems via runoff.

Maximizing Phosphorus Efficiency Is Key to a Healthy, Profitable Alfalfa Crop A nutrient-rich and yield-intensive crop is crucial to maintaining profitability, particularly as the stability of alfalfa prices remains uncertain. Managing nutrients in the soil, such as phosphorus (P), can make a big impact on success come harvest time. However, managing this essential nutrient is no easy task, and more retailers are recommending nutrient management technologies to make sure their customers are getting the most out of their fertilizer investments.

“The primary thing we are seeing when AVAIL has been added is an increase in yield,” says Petersen. “But in addition to that, we have also noticed earlier maturity, which can make a real difference in areas at higher elevations, or where the crop is maturing in cooler temperatures.”

“The primary thing we are seeing as farmers across the country continue when AVAIL has But to manage tight margins, return on for every acre remains been added is an investment top-of-mind. increase in yield,” “This past year, 80 to 90 percent of our phosphorus was treated with AVAIL, and it’s likely in a few years that number will says Petersen. be closer to 100 percent,” says Lund. “Our

Brian Petersen, sales manager for Simplot ONE’s intermountain region, recommends that farmers consider applying AVAIL® Phosphorus Fertilizer Enhancer with their fall-applied phosphorus to increase P availability and plant uptake of the nutrient. “Many farmers make their applications in the fall and winter when there are a lot of factors working against phosphorus in the soil,” he says. “That phosphorus has a lot of time in the soil, is susceptible to fixation and faces challenges such as high pH levels.” Phosphorus is critical to the health and nutrition of any crop, but that is especially true for alfalfa. “Tradition tells us that you need to apply phosphorus to your alfalfa,” says Courtney Lund, manager at Hermansen’s Mill, LLC in Gunnison, Utah. “The thinking was, if you put a hundred pounds on a crop, it was sufficient. But that isn’t taking into account any of the other factors, such as how much phosphorus is already in the ground and what other factors are at play in the soil.”

experience with AVAIL has been incredible, and our customers are seeing great results. It has helped set us apart and better compete with other retailers in the area by offering a specialty product over straight phosphate. The farmers are getting a nice return on investment for their alfalfa crop, and we are able to make some money as well.” To learn more, visit vlsci.com or call 800.868.6446.

According to Ryan Bond, Ph.D., vice president of marketing at Verdesian Life Sciences, managing phosphorus in the soil can be difficult. “While soil tests may show that a field may have adequate phosphorus levels, it may not be in a form that is available for plant uptake,” he says. “AVAIL provides real yield benefits across a range of phosphorus application rates by

PATHWAY TO PCA

Teacher Kits a Success at CATA!

Jerry Delsol, one of two workshop presenters, shares his strategies for teaching students how to identify weed specimens.

Shannon Douglass shannonrdouglass@gmail.com Pathway to PCA Consultant

n June we completed the CalAgPlate grant by coordinating a workshop at the California Ag Teachers Conference and presented 35 participating teachers with a kit of classroom materials valued at over $300 per kit. The handson workshop helped teachers learn how to use the contents of the classroom kit and best practices for training crops-related FFA teams such as Agronomy, Ag Pests and Vegetable Crops. Almost all of the contents are items which have a long life span and can be used by many students as part of classroom instruction as well as for competitive team training purposes. The workshop was an incredible success! The workshop was filled on the first day of conference and closed to additional teachers due to space limitations. We could have easily filled a second workshop from the wait list. Not only were people interested, those who completed the workshop indicated on our surveys that they were very pleased with the training and resources. Further, we got great comments from participants who requested we offer a much longer version of the workshop again in the future. As school gets back in session, we are also looking to connect these newly trained teachers with industry professionals. There are many options for how YOU can get involved, including offering tours for student teams or teachers, visiting a practicing team to help in weed or insect identification, or sponsoring one of these kits for your local high school ag program. We will be looking for your support as we work to grow this program! T

These classroom kits were valued at over $375 and included a variety of identification tools, a pest collection kit, a seed sample kit, enough hand lenses for a class and starter materials for weed collection.

Workshop participants learned strategies for identifying weed specimens and best practices in preserving samples. 12

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™.

second recipient, thereby making it possible to award both students $3,000. We congratulate 2016 Stanley W. Strew Scholarship recipient Martin Alfaro and Pedro Martinez, recipient of the Stanley W. Strew & FresnoMadera Chapter scholarship. Martin Alfaro 2016 CAPCA Scholarship Martin Alfaro is a student at Cal Poly, San Luis Obispo. His major is Agriculture and Environmental Plant Science with a concentration in Plant Protection and a minor in Crop Science. Martin holds a 3.59 overall grade point average and 3.15 in his major. Martin’s goals are to become a Pest Control Adviser and Certified Crop Adviser. Congratulate Martin in realizing the first half of his goal by earning his PCA license in July 2015 and best of luck in obtaining his CCA Certification. Martin is the eldest of eight siblings and a first generation college student. His wife and son live with him in Soledad. Having a career as a PCA means a lot to him

and his family and he hopes this sets the bar high for his siblings to follow. Martin is a member of CAPCA and has been active in the Monterey Bay CAPCA Chapter as the Secretary for the past two years. In addition, Martin also volunteers for Farm Day where third graders in Monterey County learn about our bountiful agricultural industry. The booth that he hosts teaches students about the importance of the Pest Control Adviser career. We received the following letter from Martin: “I would like to express my upmost gratefulness for my selection as the recipient of the 2016 CAPCA Stanley W. Strew Scholarship. Upon high school graduation, I began a family and started working in the fields doing general farm labor. I started working at Huntington Farms as an irrigation laborer, then moved onto the warehouse and eventually became an assistant to the in-house PCA, Mark Mason. My job involved scouting vegetable crops such as lettuce, broccoli, cauliflower and celery. Working at Huntington Farms sparked my interest in pest management and farming. After three years of putting off my education, I decided to return to school and further my education. I completed two years in community college while working full time and continued to grow my knowledge in pest

management. I obtained my PCA license in June 2015 but I was still eager to learn more. “Three years later, I am now ready to embark my last year in college as a senior at Cal Poly San Luis Obispo. In June 2017 I will graduate with my Bachelors of Science in Agricultural and Environmental Plant Science with a concentration in Plant Protection Science. Upon graduation, I plan to continue providing my services as a Pest Control Adviser at Huntington Farms. Once again thank you for your continuous support to the students pursuing careers in pest management. I hope to one day be able to contribute back to future students and ease their financial need in the same way that CAPCA is now helping me.”

Pedro Martinez 2016 Scholarship Pedro Martinez is a student at CSU, Fresno. His major is Viticulture. Pedro holds a 3.37 overall grade point average and 2.8 in his major. Pedro’s goals are to earn a Bachelor’s of Science in Viticulture and work towards his Pest Control Adviser License and Certified Crop Adviser Certificate. Pedro arrived in California at the age of eight and discovered his dream while helping his parents in the fields harvesting a myriad of fruits and vegetables. “Even though I didn’t know the name of my future career yet, at that age I knew I wanted to become a viticulturist,” stated Pedro. He especially took a particular interest in grapes; their growth and production fascinated him. At age of 17, his desire to become a viticulturist only grew stronger when he began harvesting grapes at a California vineyard. Today, Pedro is involved in three different clubs at Fresno State and works as a Research and Development Assistant. We received the following letter from Pedro: “It is an honor to receive the 2016 CAPCA/Stanley W. Strew in collaboration with the CAPCA FresnoMadera Chapter Scholarship. I was thrilled to find out of my selection for this scholarship and I am deeply appreciative of your support and generous contribution toward my education career at California State University, Fresno. “I am currently in my third semester of working towards my Bachelors of Science in Viticulture. I recently got hired at the Viticulture and Enology Research Center at Fresno State in the spring of 2016. I have been working with Dr. Sanliang Gu on one of his studies regarding the interactive effects of crop forcing in the vines on cabernet sauvignon, Shiraz, and Pinot Noir in Mendota California. I have also recently received a scholarship from the American Society for Enology and Viticulture. I was also entitled to attend the National ASEV Conference in Monterey, CA. In addition to my work history and classes, I am also in several student organizations; Fresno State Viticulture club, STAO (Stand Together As One) club, and Ritmo y Pasion Salsa Club at Fresno State. Furthermore, last May I had the opportunity to give my presentation at the Western Food Safety Summit at Hartnell College in Salinas, CA

CAPCA ADVISER | OCTOBER 2016

on my food safety research project I conducted at SmartWash Solution LLC. Throughout my studies at Fresno State, my goal is to prepare myself to get my PCA license and after my graduation in Spring 2017 I hope to work as a vineyard manager or vineyard consultant. “Thank you for your generous contribution towards my education. This scholarship has been an encouragement to keep working hard, as well as an example of giving back to the community. Receiving this scholarship has also influence me and I hope that in the future I will be able to set up a scholarship fund to help students achieve their goals.” T

CAPCA ED Update Mindy DeRohan, Manager, CAPCA ED 2016 New Locations 2016 has been a successful year for CAPCA ED. By the end of 2016, we will have hosted nearly 50 seminars and have moved into new regions throughout California. New meetings have been held in Corona, Gilroy, and San Luis Obispo and a seminar in Arcadia is planned for later this November. As the CAPCA ED team is starting to plan for 2017, the success that we have had in new areas is promising for the future. Changes to DPR Accreditation As many of you may have noticed, for seminar agendas submitted after July 1, 2016, DPR is no longer granting continuing education credit for breaks during seminars. This change makes DPR more consistent with other continuing education organizations like CCA and ISA. These changes will be reflected on CAPCA ED seminar agendas throughout the second half of the year.

Help Save California Citrus – Report Abandoned Trees

he Asian citrus psyllid and Huanglongbing have decimated the Florida citrus industry, causing over a 70% decline in production in just 10 years at cost $7.8 billion and 7,513 jobs. To date, the disease has been discovered in California in 25 Los Angeles area citrus trees. “Since the first Asian citrus psyllid was detected in 2009, the California citrus industry has known that this battle will be lost or won in the backyards of homes in Southern California,” says Joel Nelsen, president of the citrus growers’ trade association California Citrus Mutual. The Asian citrus psyllid is endemic in Southern California and is steadily spreading into commercial production areas in Ventura and the Central Valley. Now more than ever, growers and PCAs must work together to control Asian citrus psyllid populations to prevent HLB from spreading into commercial citrus groves. “This is an all-hands-on-deck crisis,” says Nelsen. “Stopping the spread of HLB is the number one objective for the California citrus industry, and that means taking all

Alyssa Houtby, California Citrus Mutual measures necessary to control the spread of ACP.” One critical line of defense is to monitor trees in residential areas that neighbor commercial groves. However, the industry is concerned with the increasing number of citrus trees that are not being treated or have been abandoned. “These abandoned trees threaten the entire citrus industry in our state, as they can serve as reservoirs for the psyllid and HLB,” says Nelsen. “We need residential tree owners to learn about this threat and partner with commercial growers to save California citrus.” A new initiative by the citrus industry hopes to solve this problem one tree at a time. The Abandoned Citrus Tree (ACT) removal program, managed by California Citrus Mutual with support from Bayer CropScience, aims to identify and remove abandoned citrus trees that are not properly managed and may be infested with the Asian citrus psyllid. To date, the program has removed over 300 trees and is currently working to remove several more acres in Ventura County.

Another complication lies in the fact that many residential properties, particularly in areas like Ventura County, contain more than 25 trees, which the California Department of Food and Agriculture classifies as commercial, and therefore not eligible for the state's coordinated residential treatment program. In most cases homeowners with two to three acres of citrus may not be properly treating for the psyllid for various reasons. California Citrus Mutual is asking growers and PCAs to report these types of properties to the ACT program. “Growers and PCAs are working hard to protect commercial citrus groves,” says Nelsen, “But, a growing number of abandoned citrus trees that are left untreated are undercutting these efforts.” Pest Control Advisers and growers are urged to submit information about abandoned citrus trees online at www.citrusmatters.us. The Asian citrus psyllid and Huanglongbing (HLB) are a death sentence for California citrus – but by working together we can save our citrus trees. T

UC IPM

Ants: Monitoring and Your Management Options Kris Tollerup, San Joaquin Valley Area IPM Advisor, UC Statewide IPM Prog. and Kearney Agricultural Research and Extension Center

nt infestations in almond produced in the San Joaquin Valley and upper Sacramento Valley region can be a substantial problem given their capacity to cause large economic loss. Pest ants can cause direct damage, such as feeding on almond nuts at harvest while they are on the orchard floor, or indirect damage by protecting honeydew-producing hemipterans, such as mealybugs and aphids from their natural enemies. California has approximately 245 native and 25 introduced ant species, yet very few of them pose an economic threat to agricultural crops. Conventional knowledge is that only three ant species, the southern fire ant, Solenopsis xyloni McCook; thief ant, Solenopsis molesta Buren; and pavement ant, Tetramorium caespitum (L.), account for the majority of ant damage (Fig. 1). The thief ant, however measures only about 0.14 mm (1/64 inch) in length and we do not fully know how much damage this ant can do. The University of California Pest Management Guidelines suggest that the mean number of ant nest openings be determined in five survey areas of about 1,000 ft2. The Guidelines provide a form and table to aid in recording sampling results and making management decisions. (http://ipm.ucanr.edu/PMG/C003/almondantcolony.pdf). An important point to keep in mind while monitoring is that not all ants you may see in the orchard are pests. Non-pest ants that often occur throughout much of the San Joaquin Valley and Sacramento Valley region almond production areas include the native gray ant, Formica aerata Francoeur; pyramid ant, Dorymyrmex bicolor Wheeler; and California harvester ant Pogonomyrmex californicus (Buckley). Other non-pest species that also occur, but to a lesser degree include, Forelius pruinosus (Roger) and Lasius spp. Since relatively few ant species commonly occur in almond and only three are known to cause damage, coarse

morphological differences, such as number of nodes on the petiole, presence of a sting, and color and size provide enough information to properly identify pest and non-pest ants. The Pest Management Guidelines provide a key to household ants (http://ipm.ucanr.edu/TOOLS/ANTKEY/ index.html), but the key also is applicable to the pest ants found in almond. You can identify ants by examining them with a 10x hand lens, but this requires that they be collected and euthanized. An effective method of capturing ants consists of placing bait such as whole FritosÂŽ corn chips or a piece of hot dog in a small plastic vial. Place 5 to 10 vials of each bait type in various locations in the orchard during the morning hours. After about two hours in the orchard cap the vial and place in a freezer for a few hours. In addition to morphological characteristics, foraging activity and behavior, nest location, and the manner in which different species deposit tailings around the single or multiple entrance holes provides useful information for identification. For instance, during hot daytime temperatures, the foraging activity of southern fire ant and the pavement ant diminishes considerably, while that of the native gray ant and California harvester ant remains high. In contrast to the two pest species, the non-pests F. pruinosus and the Lasius spp., form distinct trails on the soil surface and up into tree canopies. The native gray ant also does not form trails and moves about in very distinct herky-jerkey fashion. Nest location and architecture can vary within a species although some generalities exist. Southern fire ant tends to construct nests in shaded areas with multiple, relatively small entrance holes. Fine-grain tailings most often appear dispersed in a hilly fashion around entrances (Fig. 2). The native gray ant also constructs dispersed multi-entrance nests in shaded areas, however the entrance holes are typically much larger than southern

fire ant and tailings are of a larger grain and more flatly dispersed (Fig. 2). The native gray ant also will construct nests with large entrance holes at the base of trees, but without the evidence of distinguishing tailings. Identifying the pavement ant, and nonpest, pyramid ant based on nest location and architecture can pose a bit more of a challenge. Both species typically select more sun-exposed locations to construct single-entrance nests with tailings distributed in a volcano-like fashion (Fig. 2). Morphological differences and the quick squish-test easily distinguishes the species. When squished, the pyramid ant gives off an obvious odor. With an increased understanding of pest and non-pest ant species, UCâ&#x20AC;&#x2122;s ant monitoring guidelines will be modified to exclude nests of non-pest ants before making a management decision. Four very effective bait management options exist for almond, two insect growth regulator (IGR) baits: pyrproxyfen and methoprene, and two stomach poison baits: abametin and methoxyfenozide. Each of these baits use soybean oil as the attractant/toxicant carrier and preferentially attract lipid-feeding (proteinfeeding) ants. When deciding on a management strategy, make sure to consider the lag time between bait application and population reduction. IGR baits work slower, taking up to eight weeks before significantly reducing foraging activity. In contrast, the stomach poisons methoxyfenozide and abamectin work much faster, requiring just one and three weeks respectively before significantly reducing foraging activity. Effective ant management not only requires knowledge about the available products and their use, but also requires an end-of-the-year follow up to assess how well the selected strategies worked. The Pest Management Guidelines provide information on how to assess ant damage and distinguish it from Oriental fruit moth and peach twig borer damage. Given the capacity of ants to inflict economic damage, they are a problem. But, given the IPM tools available for correctly identifying ants and the effective management options, they should not be a problem. Insecticide use should occur only if monitoring indicates the presence of ant pests. Apply bait insecticides only after considering the potential risks of the compound to water quality. For more information on this and other topics about ant management please consult the UC IPM Pest Management Guidelines for Almonds at http://ipm.ucanr.edu/PMG/ selectnewpest.almonds.html T

Effects of Transplant Tray Drench Application of Insecticides for Bagrada Bug Control in Broccoli Shimat V. Josepha, Ian Grettenbergerb, and Larry Godfreyb University of California Cooperative Extension, Salinas, CA b Department of Entomology and Nematology, University of California, Davis a

agrada bug (Bagrada hilaris) (Fig. 1) is a serious pest on Brassica crops in the Central Coast of California. This pest is native to old world countries of southern Africa, Middle East and Asia. It was first detected in North America in 2008 in Los Angeles Co., California and is now established in the Central Coast of California. Broccoli and cauliflower are important crops grown in this region. Serious economic injury occurs on these crops when bagrada bug feeding kills the apical meristematic tissue of the young seedlings, creating a “blind head” (plant without a head), or when feeding triggers production of multiple adventitious shoots, causing plants to produce unmarketable, undersized broccoli and cauliflower heads. On some plants, severe feeding during early stages of plant growth depletes the nutrient reserves and causes stunting. Bagrada bug feeding injury on leaves appears as starbursts on leaf surfaces. Management of bagrada bug primarily relies on pyrethroid and neonicotinoid insecticides and growers sometimes resort to multiple sprays of these insecticides for adequate control. Although potential biological control agents are actively sought in the native range in Asia, their importation and subsequent field release in the Central Coast will take several years. Until sustainable tactics are developed and readily available, chemical control will remain the primary tool for management in conventionally managed vegetable production. Drenching

seedling trays with insecticide is a precise application tactic in which the insecticide dose is placed directly onto the transplant plugs before transplanting. Thus, a study was conducted to evaluate the efficacy of insecticides against bagrada bug when delivered as a seedling tray drench before planting in 2015. Experiments were conducted in both greenhouse and field settings using systemic and non-systemic insecticides (Table 1). In all experiments, we used the maximum label rate of Table 1.

damaged leaves, and number of feeding injury sites. In the greenhouse experiment, the percentage injured leaves was substantially lower than the untreated when the transplants were treated with the neonicotinoids clothianidin, dinotefuran, imidacloprid, and thiamethoxam (Fig. 3A). Compared to the untreated plants, the number of feeding injury sites (Fig. 3B) and rating on leaves (Fig. 3C) were lower on transplants treated with dinotefuran, clothianidin, imidacloprid, thiamethoxam, acetamiprid, thiamethoxam + chlorantraniliprole, imidacloprid + Î˛-cyfluthrin, and cyclaniliprole. Cyclaniliprole, in addition to neonicotinoids and bifenthrin, also had significantly lower feeding injury ratings than untreated. In the field experiment, the number of feeding injury sites was significantly lower with clothianidin, dinotefuran, acetamiprid, thiamethoxam, thiamethoxam + chlorantraniliprole, imidacloprid + Î˛-cyfluthrin, and bifenthrin than with untreated (Figs. 4 and 5A). Cyclaniliprole, in addition to neonicotinoids and bifenthrin, also had significantly lower feeding injury ratings than untreated (Fig. 5B). These results demonstrate that drenching transplant plugs with neonicotinoid insecticides, and in particular acetamiprid, clothianidin, dinotefuran, imidacloprid, and thiamethoxam, reduces bagrada bug feeding damage and promotes normal plant growth (Fig 4). We also tested non-neonicotinoid systemic insecticides as tray drenches including cyantraniliprole and cyclaniliprole, as well as contact insecticides, such as flonicamid, spinetoram, tolfenpyrad, and bifenthrin, but most did not consistently affect bagrada bug damage. The contact insecticides were tested in addition to systemic insecticides because these insecticides are commonly used as foliar sprays for various insect pests, including bagrada bug on Brassica crops, although positive results were not expected. The efficacy of tray drench application for broccoli suggests that this application method could be useful for bagrada bug management in other Brassica crops, and in particular, cauliflower. The insecticide dose received by each transplant plug was based upon the number of plants per acre, which is related to plant spacing, number of rows per bed, and width of a bed. As the number of plants transplanted in an acre decreases, the amount of insecticide received per plug will increase. In the Central Coast, cauliflower is planted at a greater spacing than broccoli, and only one row of cauliflower is typically planted per bed rather than the two rows used for broccoli in the same-sized bed. This suggests that if the same overall rate of insecticide is used at the field level, each cauliflower transplant will receive a larger insecticide dose than broccoli transplants because of the lower number of plants per acre. Our results show that bagrada bug was adequately controlled by the neonicotinoid insecticides when applied to broccoli transplants. Thus, cauliflower transplants, which would receive a higher dose than broccoli at the same per acre rate, should

perform even better. Future research will investigate the efficacy of lower rates of neonicotinoid insecticides, and in particular dinotefuran and clothianidin, against bagrada bug in cauliflower. We may be able to still achieve sufficient control of bagrada bug in cauliflower by reducing the amount of insecticide applied on a per-acre basis compared to broccoli, but keeping the rate the same at the individual transplant level. Although application of systemic insecticides as a seedling tray drench would provide benefits for managing B. hilaris, the only product registered for seedling tray drench to date on Brassica crops is cyantraniliprole. Application as a tray drench is not yet a registered use for neonicotinoid insecticides. Factors such as water volume, time of application, and insecticide properties for tray drenching may influence the efficacy of insecticides. The water volume used to apply the insecticides may be critical for placement of insecticides in the root zone of the plug. The quantity of solution should be low enough that it will not leach from the plug, which would waste insecticide and increase waste management problems. In this study, the ideal water volume was determined after a series of preliminary experiments to identify the maximum volume of insecticide solution that could be applied without leaching loss. The insecticide solution in this study was also injected using a syringe rather than sprayed with overhead sprinklers (Fig 2). In a commercial setting, the seedlings in the trays will likely be chemigated, and both the foliage and roots will be exposed to insecticides. The amount of insecticide solution received per seedling will depend on the set-up of the system, frequency, and pressure of the irrigation events. In this study, the interval between tray drench and transplanting was not uniform, although effective insecticides had activity within a time period of 0-3 weeks between insecticide application and transplant. In conclusion, this study clearly shows that neonicotinoid insecticides were very effective against bagrada bug as a systemic application through a tray drench. Drenching transplant plugs with neonicotinoid insecticides protected plants from bagrada bug feeding beyond five weeks, which is the most vulnerable phase of crop development to bagrada bug feeding and injury. This suggests that if neonicotinoid insecticides are registered for this application method, it could reduce the need for multiple applications of foliar insecticides beginning at plant emergence. Cauliflower is 100% transplanted in the Central Coast while broccoli is ~95% transplanted in the southern half of the California, so tray drenches with neonicotinoids could provide a vital tool to help protect these crops from bagrada bug.

Make the leap to liquid Tuscany SC: the first flowable flumioxazin, now available in California. By Alan Haack Ph.D., Nufarm Technical Services Manager

For years, flumioxazin has played a key role in providing dependable residual weed control in orchard and vine crops across the state. Since its launch in 2003, however, flumioxazin (sold as Chateau or Tuscany) has been available only in a WDG formulation, which can cause some application issues, as the water-dispersible granules don’t always rapidly disperse into suspension. This can lead to an uneven distribution of active ingredient in the spray solution, leading to uneven application on the ground.

In the photos below, you can see the dramatic difference in suspension between SC on the right and WDG on the left, including the undissolved granules at the bottom of the WDG cylinder. Tuscany SC has been tested extensively in other markets, and has performed flawlessly. If flumioxazin is in your field recommendations for weed control in the upcoming season, take a look at Tuscany SC.

Several years ago, the formulation chemists here at Nufarm took on the challenge to build a better flumioxazin formulation. The end result is Tuscany ® SC, a suspended concentrate flumioxazin that measures ounce-for-ounce (1 fluid ounce equals 1 dry ounce of WDG) with 51% WDG formulations, but offers much improved mixing and suspension capabilities.

A video demonstration of Tuscany SC mixing is available at nufarm.com/us or contact your local Nufarm representative for more information. NORTH mark.allen@us.nufarm.com

Best Ways to Ward Off Worms in Lettuce and Cole Crops Effective lepidopteran control requires the right soil application techniques, followed by tight spray intervals. Photo courtesy of Dr. John Palumbo, Research Entomologist, University of Arizona

ields of tender, young lettuce and broccoli look very appealing, especially to insects. Whitefly, thrips and aphids can definitely impact leafy vegetable and cole crop quality, but lepidopteran species pose the biggest insect threat, especially in fall produce grown in the desert southwest. Lepidopteran pests, including beet armyworm, cabbage looper, corn earworm and diamondback moth larvae, cause the most damage to lettuce and cole crops in the southwestern United States, says John Palumbo, research entomologist, University of Arizona. “We typically see higher levels of fall lepidopteran pressure in September and October. When evening temperatures remain warm into late October and November, worm activity often continues. That was the case in 2013 and 2014, when growers had to deal with worm pressures well into November.” While the 2015 fall season brought normal temperatures and pest levels, there’s a real possibility growers could face a warmer fall and extended worm pressures again this year, he notes. “For leafy vegetable crops, the threat from beet armyworm and cabbage looper begins at emergence. The potential for crop damage is greatest in the first few weeks, when feeding can significantly reduce stands.”

Soil-applied control

“Coragen® also offers plenty of application flexibility and can be applied as an in-furrow spray or surface band at planting, or in transplant water, through drip chemigation or as a foliar spray.

Preharvest challenges Keeping lettuce and brassica crops pest-free until harvest hasn’t been easy in recent years when corn earworm pressures flared, notes Palumbo. “Corn earworm pressures in 2014 were off the charts, the highest we’d seen in the last 15 years, and there’s no simple explanation for it.” He speculates that one reason the pest wasn’t as prevalent in 2015 was because PCAs were scouting more frequently and tightened spray intervals. “There’s not much room for error with corn earworm control. Once they lay eggs and larvae bore into heads, the battle is lost.” He says making sure there is a consistent, effective barrier on fastgrowing plants is the only way to achieve thorough control of corn earworm. “That’s critical to delivering a bug-free crop at harvest.” “Coragen® is an important foliar treatment alternative for growers who had been using insecticides containing flubendiamide (Belt and Vetica), which recently lost EPA registration,” says Pacheco. “Coragen® works fast, is effective, provides broad-spectrum lepidopteran and leafminer control, has minimal impact on beneficial species, and fits well into an integrated pest management program.”

An effective approach for early season control is a well-executed atplant soil application, says Jeff Pacheco, technical sales agronomist, DuPont Crop Protection. “Soil shank injection at planting, followed by sufficient irrigation, is a very effective application method for DuPont™ Coragen® insect control (Group 28). Injecting it uniformly 1 to 2 inches directly below the seed line, at a rate of 5 fluid ounces per acre if targeting lepidopteran species, and up to 7.5 fluid ounces per acre for leafminer larvae control and whitefly nymph suppression, allows it to be easily taken up by developing seedling roots. As the young plant grows, Coragen® is translocated throughout the plant tissue, providing protection at emergence.”

To prevent insecticide resistance, it’s important to avoid making consecutive applications of insecticides with the same mode of action on successive generations of the same pest, he adds. “No resistance issues with lepidopteran pests have developed yet in desert produce, and following good management plans with proper product rotations should help keep it that way.”

Young plants are least able to tolerate insect feeding in the first few weeks after emergence, says Palumbo. “Coragen® provides good residual control – for 25 to 30 days – when young plants need it most.”

• Extended residual control when Coragen® is within the plant

When applied by soil shank injection, Coragen® provides the longest-lasting protection against destructive lepidopterous worm pests, and stops feeding within minutes of exposure, adds Pacheco. “It controls larval stage lepidopterous insect pests, including beet armyworm, cabbage looper, corn earworm and diamondback moth larvae in head and leaf lettuce, broccoli, cauliflower and cabbage.”

New Troubles From the Glassy-Winged Sharpshooter

nvasions by new arthropod vectors can bring with them new pathogens, causing novel disease outbreaks in an area. Alternatively, new vectors can alter the dynamics of existing diseases – in some cases causing more frequent or more severe disease outbreaks. The latter scenario unfolded following the establishment of the glassy-winged sharpshooter (GWSS; Homalodisca vitripennis) in California approximately 20 years ago. Glassy-winged sharpshooter (Fig. 1) is native to the southeastern US, where it is one of the main vectors of the bacterium Xylella fastidiosa that causes a range of plant diseases, including Pierce’s disease (PD) of grapevines. All commonly grown varieties of grapevines are susceptible to this bacterium, which causes progressive leaf scorch, defoliation, and ultimately vine death (Fig. 2). Pierce’s disease has likely been a problem for as long as grapes have been grown commercially

in California, having been first identified here in the late 1800s. Yet following the invasion of GWSS, outbreaks occurred that were more severe than usual. GWSS was first detected in Southern California in the late 1980s. A decade later PD outbreaks began to occur in Temecula Valley. A few years after that, portions of the southern San Joaquin Valley faced similar PD outbreaks associated with the establishment of GWSS there. Although not as efficient at transmitting X. fastidiosa to grapevines as some vectors, particularly the native blue-green sharpshooter (GWSS; Graphocephala atropunctata), GWSS is notable for its use of a wide range of plants for feeds and reproduction. This broad host range likely favors its establishment in new areas, and high abundance of certain favored plants contributes to its ability to reach far greater

densities than native vectors. During the outbreaks in the Temecula Valley approximately 15 years ago there were anecdotal reports of “100s” of GWSS per vine. The most significant PD problems occurred in vineyards adjacent to citrus plantings, which are preferred host plants for GWSS. In response to the PD outbreaks driven by GWSS’s invasion, state and federal regulators, in conjunction with researchers and extension personnel, initiated area-wide control programs in affected areas of California: Temecula Valley and Coachella Valley in Southern California, along with portions of Kern, Tulare, Fresno and eventually Madera County. This included extensive monitoring for the vector, area-wide insecticide applications targeting primarily citrus to reduce GWSS spillover into vineyards, and mass rearing and releasing of multiple species of parasitoids that attack GWSS eggs (Gonatocerus spp.). Other steps included regulating the movement of nursery stock to minimize its potential for inadvertently contributing to GWSS spread, and eradication efforts around GWSS detections in new areas of the state. Finally, grape growers in affected areas took an increasingly active role in disease management in their vineyards via chemical control of GWSS and removal of infected vines. Collectively, these steps reduced greatly GWSS pressure and Pierce’s disease prevalence. For example, trapping data from Southern California in the late 1990s showed peaks of more than 20 GWSS per trap per day compared to peaks a few years ago of under 0.1 GWSS. Similarly, surveys of Temecula Valley vineyards completed in 2012 estimated that just 0.5% of vines in the region had Pierce’s disease. Moreover, regulatory steps taken to slow the spread of GWSS outside of heavily infested areas in the southern half of the state appear to have been largely successful in as much as its distribution remains restricted generally to where it has been for nearly 10 years (Fig. 3).

The current situation Despite notable successes with managing Pierce’s disease for more than a decade, it remains one of the most significant challenges for grape production in California, in part due to GWSS, with total losses and management costs estimated to be more than $100 million per year. Indeed, over the last few years troubling trends have emerged suggesting a resurgence in Pierce’s disease severity in several major grape-growing regions of the state. In areas where GWSS is widely established, its abundance appears to be on the rise again. For example, in Temecula Valley the area-wide trapping data so far in the summer of 2016 has shown peak trap catches that are 2-3 times higher than have been seen since 2009. Far more problematic, however, is the clear rebound in GWSS populations

“In areas where GWSS is widely established, its abundance appears to be on the rise again.” in the Southern San Joaquin. For example, GWSS trap catch from the Kern County area-wide monitoring program has increased more than 10fold since 2008 (Fig. 4), with marked increases in PD prevalence in the area as well. The reasons for the apparent resurgence in GWSS populations in parts of California are not definitively known. One potential explanation is tied to climate – specifically, temperate winter and spring conditions the last few years. GWSS stop feeding below approximately 50°F, and desiccate and die if exposed to low temperatures for several days. Therefore, warmer and less foggy winters may have contributed to higher GWSS abundance. A second

Grape Growers Trust the Proven Strength in Arysta LifeScience Products

Like many who plant and raise food and crops, grape growers fight disease, insect and weed pressure. Pests ranging from Powdery mildew and Botrytis bunch rot to spider mites can get in the way of successful growing seasons and yields. In the grape market, it’s important to have a strong arsenal of protection. Working together to fight disease, insect and weed pressure, both singularly and via tank mixes, the family of Arysta LifeScience products for grapes offers numerous solutions, including:

ACRAMITE®-50WS Miticide offers rapid,

VITICURE® Fungicide gives grape growers an

versatile protection against a variety of spider mites, at all life stages, in grapes up to 30 days after treatment. Additionally, ACRAMITE is easy on beneficial insects and predator mites. This product should be rotated or tank-mixed with miticides with different modes of action to prevent resistance issues as part of a resistance management program.

economical and highly effective option that goes beyond prevention of Powdery mildew through reach-back activity to help cure existing infections. A locally systemic protectant fungicide, VITICURE is unique — it is an imidazole that has no known cross-resistance to other Group 3 DMI fungicides.

ELEVATE® Fungicide gives wine and table grapes the protection they need against Botrytis bunch rot. ELEVATE is a member of the FRAC group 17 fungicide class, making it an excellent fit in resistance management plans. When used in spray programs, ELEVATE will ensure effective disease control while preserving a grape grower’s fungicide options for years to come.

PH-D® Fungicide is a Group 19 broad-spectrum fungicide with a mode of action that inhibits fungal cell wall formation by interfering with the production of chitin in the fungal cell wall and provides control of Bunch rot organisms like Botrytis and Cladosporium, while suppressing Powdery mildew. When tank-mixed with VITICURE, it offers grape growers a powerful tool for control of Botrytis and Powdery mildew in a single spray.

potential explanation relates to ineffectiveness of chemical control programs. Such problems may manifest due to a reduction in efforts to target GWSS, shifting timing of applications to target other pests that is less effective at managing GWSS, or the evolution of insecticide resistance. The last of these potential explanations is currently being studied to reevaluate the efficacy of some of the common systemic and foliar insecticides that have been used against GWSS since its invasion. In the meantime, until the reasons for the resurgence in GWSS populations are clarified, it is increasingly important to renew efforts to manage this important vector and disease. Pierce’s disease management Pierce’s disease management employs the same general set of tools as for other vector-borne plant pathogens. Because there are not yet any truly PD-resistant wine grape, table grape, or raisin varieties that are widely available, management relies on a combination of controlling vectors and reducing pathogen supply. The challenge with managing Pierce’s disease is that both the pathogen and the vectors, particularly GWSS, have broad host ranges – meaning there are potentially several targets for management. The area-wide programs continue to be an important element of GWSS control and Pierce’s disease management. Yet, some details have changed over time. In the San Joaquin Valley, the programs continue to include extensive monitoring, application of systemic and foliar insecticides targeting primarily GWSS populations in citrus, and releases of GWSS egg parasitoids in select areas. Meanwhile, the Southern California programs involve primarily monitoring for the vector. Area-wide chemical control and biological control releases are no longer occurring in the region – though observations indicate that the parasitoids are widespread and are likely an important part of sharpshooter suppression later in the season.

In addition to any ongoing areawide management, grape growers can actively contribute to Pierce’s disease management in multiple ways. These include the following: Vine roguing: Particularly in warmer regions, infected vines aren’t likely to recover from infection. Therefore, diseased vines should be removed to minimize their potential to contribute further to pathogen spread. Vines should be inspected in the fall when PD symptoms are most apparent. Suspected vines, particularly those with severe PD symptoms, should be flagged for later removal. Areas within vineyards that have persistent PD problems should be replanted with relatively less susceptible varieties. Vegetation management: Several species of plants, in addition to grapevines and citrus can be sources of the pathogen or vector. This includes several common weedy forbs and grasses in and around vineyards, which should be managed via tilling, mowing, or herbicide applications to minimize their roles in contributing to pathogen spread. Similarly, GWSS readily uses many common ornamental species as reproductive hosts. Vineyards and wineries should avoid landscaping with certain plants, including olive, citrus, roses, photinia, and other key GWSS reproductive hosts. An

extensive list of GWSS host plants can be found at the Pierce’s Disease Control Program site listed below. Vector control: Multiple insecticides are available for use in vineyards to control GWSS. For conventional growers, soil applications of systemic neonicotinoids are regularly used in most areas where GWSS is established as long as the soil type allows for rapid uptake into vines. Application timing may vary among areas, but typically should occur by the end of spring to allow for GWSS-effective concentrations in vines for much of the remainder of the season. For organic growers, options include kaolin clay and pyrethrins. Given the short residual efficacy, especially for the latter, successive applications at 1-2 week intervals are recommended starting in the late spring or early summer depending on the results of vector monitoring.

Weedy Rice in California: Where Does It Come From and What Can We Do About It? Whitney Brim-DeForest, UCCE Rice Advisor

Red rice ligule

eedy rice is one of the most competitive weeds of rice worldwide, and it is found in most rice-growing regions of the world. Its origins are difficult to determine, but it did not originate in just one location. Instead, populations evolved independently in multiple locations worldwide, sometimes with multiple events occurring in one location. Thus, weedy rice populations are not the same all over the world. They are genetically different and the outward appearance of each population varies. Traits such as seed shattering and dormancy (ability to persist in the soil), as well as the ability of the weedy rice plants to outcompete domesticated varieties for resources are the defining characteristics of a weedy rice. Weedy rice can be “red” when the bran is reddish in color, but there are also some weedy rice populations that do not have red bran and are golden or white in color when milled. In the Southern United States weedy rice populations have been split into different categories depending on their weedy characteristics and their outward appearance. Two of the most prevalent populations are categorized 54

CAPCA ADVISER | OCTOBER 2016

as “blackhull” and “strawhull.” The blackhull populations have a dark hull and long awns, whereas the strawhull populations have a light-colored hull and no awns, and are similar in color to the domesticated rice varieties. Both have characteristically reddish bran. However, even among these two groups, there is variability in seed color, bran color, awn length, plant height, and color. The origin of weedy rice in the southern US is thought to have been from the de-domestication of cultivated indica and aus varieties, at some point during the early days of rice farming in the 1800s. Weedy rice was first discovered in California in the 1930s, and the last time it reappeared was in 2003. By 2009, it was thought to have been eradicated. This year, populations have been found in Yuba, Sutter, Butte, Glenn and Colusa counties. Preliminary analysis suggests that there are many different genetic populations present throughout California. They are variable in appearance: some have awns, some do not; some have light-colored hulls, some have dark-colored hulls. Most of the populations can be characterized by their light green foliage and most

are taller than our cultivated rice varieties. The origin of weedy rice in California is currently unknown. It may due to: 1) de-domestication of cultivated varieties; 2) hybridization between an unknown weedy rice and cultivated varieties; and 3) imported weedy rice. Further investigation is necessary to figure out the source. Since we have many different populations, there is not one person or party that is responsible for the introduction of weedy rice into California. Likewise, there are a number of factors contributing to its spread. As we move into the future, it will be important to characterize all of the populations present in California’s rice-growing region, so that we can find out more about them and how to control them. This will involve collection of plants and seeds from every infested field. The identification and characterization is going to take involvement from all players in the industry, including breeders (both public and private), growers, Pest Control Advisers, and regulators. T

Harvest

AfriKelp® LG-1 is a liquid seaweed concentrate extracted from the freshly harvested South African giant brown seaweed Ecklonia maxima. It grows in clean southern oceans of South Africa (The Gansbaai/Hermanus area), known for its sanctuary for whales and other marine life, and is far from harbours and pollution. Two ocean currents, the Indian and Atlantic, meet at the tip of Africa, produce nutrientrich water and a high level of wave action, making a strong, fast growing plant. QUALITY Quality Selection: Only carefully selected, handpicked, quality kelp is used for AfriKelp® LG-1. Cold Micronisation Process (CMP) The cellule is cut mechanically in the unique process called in cold environment to ensure the quality of product. Freshly harvested kelp is immediately processed to ensure retention of quality CONSISTENCY Afrikelp LG-1 is a natural, phyto bio-stimulant rich cocktail filtered to less than 30 microns AfriKelp® LG-1 has a Natural Growth Elements (NGE’s) that help to increase the root growth, shoot growth, fruit set and fruit retention. Every batch are tested by an independent laboratory to check exact biostimulant levels. EFFECT OF AFRIKELP IN POST HARVEST FRUIT and NUT TREES To get good spring budding trees and vines, It must start from having an appropriate post-harvest nutrition program, so that the plant can absorb a mass of nutrients, and thus generate a good level of reserves, like arginine. During this period, there is a second root growth peak or root flush and the last fertilization of the season. AfriKelp®LG-1 is a bio-stimulant that improves the root growth, mainly in the root growth peaks, and it will help the plant to be more efficient in the water and nutrient absorption. www.afrikelpusa.com 800-AKUSA26

Controlling broadleaf weeds in difficult conditions Prowl H2O herbicide and Treevix herbicide offer almond growers complete control ®

California almond growers are familiar with the uncontrollable forces that can destroy their orchards and rob them of their yields. Scorching heat and drought conditions have left many growers dealing with a multitude of issues, including stubborn broadleaf weeds.

Proven Preemergent Control A preemergent herbicide application at the start of the season is key to effective weed control. As an industry leader, Prowl H2O herbicide has a proven track record of protecting against strong persistent weeds and grasses, especially those germinating in the spring and summertime. Other key benefits of Prowl H2O herbicide include: Low volatility and increased stability on soil surfaces

“Difficult weeds have a tremendous capacity to spread throughout an orchard,” said Amanda Eade, BASF Specialty Herbicides Product Manager. “When faced with harsh weather conditions, it is important to get the most out of every acre.” Prowl H2O herbicide and Treevix herbicide from BASF offer almond growers superior control of both preemergent and postemergent broadleaf weeds.

Low water solubility under the toughest weather conditions Reliable and proven crop safety

Revolutionary Postemergent Control Powered by Kixor® herbicide technology, Treevix herbicide offers a unique chemistry for control of the toughest broadleaf weeds. Especially effective against tough weeds like pigweed, shepherd’s purse and groundsel, it gives growers a tree-safe application with timing flexibility and the ability to tank-mix with other herbicides. Other key benefits of Treevix include: Flexible application timing window Easy-to-use, low use rate of 1.0 oz/A Rainfast in one hour

BURNDOWN + LONG-LASTING FLEABANE, MARESTAIL, FILAREE, MALVA

Pindar® GT herbicide is a pre- and post-emergence

herbicide for almonds, walnuts, pistachios and pecans. It is an excellent fit in “residual” weed control programs that provide up to six months of clean strips in orchards and minimize the number of contact herbicide applications needed for clean-up sprays.

Burndown Activity Both active ingredients in Pindar® GT – penoxsulam and oxyfluorfen – provide post-emergence activity on the same 51 broadleaf weeds labeled for pre-emergence control. That “burndown” activity is a significant attribute. Ideal timing of residual herbicide applications is often in the fall before rains occur and before new weeds emerge. However, these “spray the dirt” applications aren’t always feasible. By the time residual herbicides are applied, some weeds have already emerged or have germinated but remain under the soil surface. The burndown activity of Pindar GT will control those emerged weeds.

Long-Lasting Performance With its two modes of action, Pindar® GT provides consistent, long-lasting control of winter and summer broadleaf weeds. Since its introduction, Pindar GT has been applied to hundreds of thousands of tree nut acres in California under widely variable conditions. Despite the weather variations, weed control provided by Pindar GT has been consistent and long-lasting across geographies, soil types and rainfall levels. Excellent control was achieved on all major weeds, including fleabane, marestail, and glyphosate-resistant fleabane and marestail. Furthermore, at the 3 pt/A rate, the residual control often lasted more than six months.

DPR has approved Botector® for use on stone fruit and almonds in California giving growers a new tool in controlling blossom blight and brown rot

Brown rot is a destructive disease that can significantly impact crop quality and yield

Botector® application timings are optimized to protect the plant at its most vulnerable physiological stages. It is important to apply Botector® prior to weather conditions (i.e. a rain event) that are favorable for the onset of the disease. If a weather25.0model is available for the crop in question, it is recommended that applications 20.0 be fine-tuned accordingly.

Botector can be used in both conventional and organic crops. The active ingredient in Botector® consists of two strains of5.0 Aureobasidium pullulans, a yeast-like fungus that is commonly found on the surface of0.0 fruit and flowers. 10.0

Percent Incidence

Botector® has proven efficacy in more than five years of research and commercial trials under a variety of growing conditions. Botector® is exempt from Maximum25.0 Residue Limits (MRL’s), so there is no PreHarvest Interval (PHI), making it an ideal 20.0 product to use when pesticide residues are a concern. 15.0

Botector® must be applied prior to onset 10.0 of the pathogen infection as a preventative because it has no direct toxicity to the pathogenic organisms. A. pullulans does 5.0 not produce antibiotics or toxins as its mode of action is competitive exclusion. The 0.0 active ingredient in Botector® outgrows

For many crops the application timings are discreet times during the growing season 10.0 and one example is the late bloom window in grapes, when petal scars can serve as a 5.0 site for infection by Botrytis cinerea. Postveraison in grapes is another window for 0.0 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 fruit25.0are recommended for the control of those diseases. For crops which are continuously harvested, applications of 20.0 Botector® should be made as long as the weather indicates disease pressure. It is 15.0 also important to continuously treat crops such as berries that have newly emerging 10.0 susceptible plant tissue. As with all contact pesticides, good coverage is critical.
