DISEASE PROTECTION FOR HIGHER YIELDS AND QUALITY.

WINE, TABLE, RAISIN GRAPES

Grape growers face a variety of tough diseases in the vineyard, from Powdery mildew and Botrytis to Black rot and Phomopsis. Not only do these diseases cause serious losses in crop yield and quality, but they can also overwinter and cause problems on your vines from season to season if left untreated. Preventing, managing and eliminating these diseases is essential to protect your investment in your wine, table and raisin grapes.

DISEASE THREATS

DISEASE CONTROL

POWDERY MILDEW

TREATMENT

If insufficiently controlled, symptoms of Powdery mildew can include red, blotchy areas on dormant canes; chlorotic (loss of greenness) spots on upper surfaces of the leaves; white, powdery or dusty areas; and white, powdery masses settled on the entire berry surface.

WELL-DESIGNED PREVENTIVE PROGRAMS

Treatment methods for both diseases are similar, which helps growers maximize efficiency for their fungicide applications and time in the field. To maximize return, growers can select a fungicide that is highly effective on both diseases for the key timings.

MANAGEMENT AND PREVENTION The University of California, Davis, recommends several practices to manage Botrytis, including:

BOTRYTIS According to the University of California Cooperative Extension, Botrytis spores, if left untreated, can infect intact, healthy flowers and shoots during bloom, and then develop later as fruit matures, devastating your grape quality and overall crop yield.

Leaf removal Applying fungicides properly Planting resistant varieties Canopy management

DOUBLE TROUBLE Powdery mildew and Botrytis bunch rot diseases often go hand in hand in vineyards. Untreated severe Powdery mildew can lead to Botrytis, causing mounting threats for wine, table and raisin grape growers. Becoming familiar with available treatment options for both diseases can minimize yield loss and quality reduction.

POWDERY MILDEW CONTROL In 8 years of running trials, Dr. Gubler of UC, Davis, has shown Luna Experience® and Flint® to be a top-rated rotational program.

From the Editor CAPCA – Membership Driven

s a member-driven association, feedback continues to drive CAPCA programs forward. Feedback comes in many forms, from low registration numbers for a CAPCA ED meeting location to the decision to launch the Leadership Institute after a successful series of pilot programs. Feedback shaped our decision to revitalize Pathway to PCA in response to the retirement numbers from our 2015 demographic survey. Feedback drives the Conference Committee to recommend the Disneyland Hotel for our Southern California CAPCA Conference despite selling out in 2016, because of the beloved family atmosphere. CAPCA is driven by all this feedback as we grapple to prioritize programs, allocate staff time and invest finances in developing new ways to serve and support our PCA membership. One point of feedback I hear often is the pride members feel that CAPCA maintains the ability to lobby to protect the integrity of the PCA license. This has long been a very clear goal to guide our involvement at the Capitol and with regulators. In 2017, with the support and advice of the Exec Committee, CAPCA Board and government relations committee, we are reviewing the priorities for advocacy. With advocacy noted as a top benefit of CAPCA membership, I am looking forward to the process of setting goals for 2017 and beyond to better align our engagement to reflect the pride, professionalism and concerns of our membership.

LEADERSHIP

Volunteers Strengthen CAPCA Rick Wescott, CAPCA Chairman

would like to start by thanking CAPCA’s past chairman of the board, John McClenahan (pictured here as I present to him his past chairman’s plaque at our February board meeting), for his dedicated service to CAPCA the last two years. He was charged with the task of keeping everything together within CAPCA during our transition to a new President and CEO, which turned out to be a longer process than anticipated. Because of his hard work and dedication I am happy to report we are in very good hands with Ruthann Anderson as our President and CEO. Thank you John! Speaking of service, I would like to ask for volunteers to get involved with CAPCA beyond just being a member. CAPCA exists because of its membership, but is effective because of the many volunteers that help run the organization. Many of you are already involved with your local chapters as board members or serving on a committee, which is where it all begins. We also need to become more active in our local communities and telling our story of what we do as PCAs and how it benefits all of us. Volunteer as a guest speaker for local clubs or schools and educate them about agriculture and the safe affordable food that agriculture provides. We also need to educate our legislators about our profession and how it is necessary to provide abundant food now and into the future. Make an appointment to talk with them or offer to meet them for lunch or better yet take them for a ride and show them what is happening in the field. An educated legislator is much more likely to listen to our concerns than one that has no idea what we do. Of course there are also opportunities to serve at the state level of CAPCA, which has several committees that are in need of people to participate. Many of these committees use conference calls to meet so it does not disrupt your entire day with travel or overnight stays. If you are interested in getting more involved, call or contact the State

CAPCA office and the staff will put you in contact with the committee chair of the committee you are interested in. Yes, volunteering can be time consuming and add to an already busy work schedule. It can also be very rewarding and help you further your career and give you valuable leadership experience. If you have been in this industry for a long time and your career is winding down, maybe this is a good time to give back to this great profession that has given all of us so much in return. So what do you think? Give it a try, you just might like it. I do! T

PATHWAY TO PCA

CAPCA and California FFA: Positively Influencing the Future of the PCA Profession Katie Otto, California FFA Foundation

CA FFA: What tools in the kit have been the most helpful? LR: The vegetable identification cards because they have the name and really nice pictures, the small study cards for pest and weed identification are useful for the vegetable crops team.

n June of 2016, 35 resource kits exposing FFA students to specific career opportunities in plant science were distributed by the Stanley W. Strew Education Fund and CAPCA. Since then CAPCA and the California FFA Foundation have been monitoring use of the kits and determining the impact. Below is a recent Q&A with a FFA chapter that received a kit. About Liberty Ranch FFA: “Liberty Ranch FFA located in Galt, Calif., has nearly 600 student members pursuing one or more pathways in the areas of Agriscience, Agriculture Mechanics & Welding, Agriculture Power Mechanics, and Floriculture & Horticulture. Our students are highly competitive in Career Development Events (CDE) and Leadership Development Events competing at the National level in at least one area for the past five years in a row. As a newer program we are developing an outdoor area with 55 raised beds, as well as a small vineyard and fruit tree orchard for hands-on applications of skills learned in our classes.” California FFA (CA FFA): Tell us why you were interested in receiving one of the 35 classroom resource kits provided by CAPCA and the Stanley W. Strew Education Fund? Liberty Ranch (LR): In developing the curriculum for the Food Science From Farm to Fork class, a large component of the course contained knowledge and understanding of crop production units such as weed, pest, vegetable, and seed identification and evaluation. From the description of the resource kit, I thought it would be an excellent resource for my course. CA FFA: Were you already teaching units on pest management or crop science? LR: No.

CAPCA ADVISER | APRIL 2017

CA FFA: How did the initial training provided by CAPCA at California Agricultural Teachers’ Association conference prepare you for utilizing the kit? LR: The best part of the training was acquiring useable resources for my Food Science From Farm to Fork class, and opening my eyes to the Vegetable Crops CDE. I became excited about the possibility of coaching a new team that directly correlated with my curriculum. CA FFA: How have you used the kit in and outside the classroom? LR: I have used the kit in my Food Science From Farm to Fork class for vegetable, seed, and weed identification. I use the kit outside of the classroom to coach my vegetable crops team for vegetable, seed, and weed identification. I have made online practice quizzes (Quizlets) from the materials which allows students to study from their phone, take practices quizzes, and play other games utilizing the content.

CA FFA: What additional resources or tools would help you better utilize the kit in or outside of the classroom? LR: The seed identification is useful for the Agronomy CDE, and although useful, I would love one for the Vegetable Crops CDE. In addition, my students find pest infestation really interesting and also the spread of pests and disease. A case study of West Nile or the Glassy Winged Sharpshooter would be very useful. CA FFA: Do you feel this kit helps enlighten students on the diversity of Agricultural careers including the PCA license? LR: In my opinion, students know about three to five ag careers; Ag Teachers, Veterinarians, Ag Welders, and Livestock Producers to name a few. ANYTHING we can do to expose students to the wide-array of available, high-paying careers in the plant science and food science areas is appreciated.

NEMATODES BEST MANAGEMENT PRACTICES2

Nematodes are microscopic roundworms that feed on plant roots, causing devastating vigor and yield reduction across the vineyard. According to the University of California, above-ground symptoms of nematode damage are mostly unthrifty vines.

ROOT-KNOT NEMATODES CAUSED

Field evaluation and nematode sampling: It is crucial to identify the nematode species present and estimate the population size through nematode sampling.

IN ANNUAL LOSSES TO THE WINE INDUSTRY

Vineyard preparation pays off: Vineyard preparation can also include the use of fumigation, where suitable, to help lower nematode populations when initially planting a vineyard.

Nematode infestations are commonly found in areas of the vineyard where vines lack vigor, growth and abundant yields. Effective nematode management relies on a variety of measures that can help enhance vine longevity and yield. UCCE – Kern County four-year trials show:

Virus transmission considerations: Some nematodes are vectors to plant diseases that should be eliminated before establishing new vineyards.

AG COMMISSIONER PROFILE

Ruben Arroyo:

Challenges, Highlights and Successes in Kern County By: CAPCA Staff

uben Arroyo is Kern County’s Agricultural Commissioner and Sealer of Weights and Measures. He has served in this position for nine years, but has over twenty-seven years of experience within the County Commissioner system, including eight years as Deputy Commissioner/Sealer in Kings County. He received his B.S in Agricultural Business from California State University, Fresno and started off as a Seasonal Agricultural Biologist with Fresno County in 1989 before working his way up to his current position. Describing the role of the Ag Commissioner, Mr. Arroyo explained that his role is to provide local administration of programs necessary to promote and protect the agricultural industry, the environment, businesses, and the public. This is done under general policy direction and oversight from United States Department of Agriculture, California Department of Pesticide Regulation, and the Division of Measurement Standards. The laws and regulations pertaining to agriculture are found in provisions of the California Food and Agriculture Code, Code of Regulations, Business and Professions Code, and County Ordinances. With so many levels of government, it can be a complicated job. In Kern County, Ruben and his staff attempt to provide assistance and guidance to help the regulated community obtain or maintain compliance but also investigate violations and take enforcement action when necessary. “The [ag commissioner] is charged with providing predictability and fairness in the enforcement of these laws and regulations while maintaining an environment of trust and transparency.” One of the most important actions he has taken during his tenure is to foster open communication and partnerships with the regulated industry, community groups, and related government agencies on issues of mutual interest. This has included a relationship with CAPCA, local PCAs and industry within the county. “The relationship has been nothing short of stellar.” He credits the industry with understanding the issues the County has had to overcome and working together as a community to develop solutions. “I have just been lucky enough to have been part of that process. The openness of the PCAs and the support of CAPCA to listen and express their concerns has been both beneficial and crucial to me making important decisions.” Better communication and collaboration have been cornerstones to his success. “I am convinced that a successful commissioner is defined by strong relationships and open, honest communication. All work is done through relationships and communication is the heart and

CAPCA ADVISER | APRIL 2017

soul of relations. So we need to shed this need to protect ourselves. We must extend ourselves to all affected parties. As commissioner, I feel it is my job to be always mindful of this and look for areas [of concern] and bring everyone up to a fair playing field.” Along with state-wide challenges for agriculture like water and water regulations, the cost of doing business in the state, issues around medical marijuana, environmental regulation and over regulation, and the loss of products/ pesticides without alternatives, Mr. Arroyo sees as specific challenges for agriculture in Kern County. Particularly, the introduction of invasive pests and associated costs, like Asian Citrus Psyllid (ACP)/ Huanglongbing (HLB) which threatens citrus trees, and the Glassy Winged Sharpshooter (GWSS) / Pierce’s Disease (PD) - a bacterium that kills grape vines. The 2015 gross value of all agricultural commodities produced in Kern County was $6,878,823,690 and the top five commodities for 2015 were Grapes, Almonds, Citrus, Milk, and Cattle (making up more than $4.6 Billion). Economically, eliminating or eradicating both these invasive species is a high priority. “Currently HLB does not exist in Kern County. In an effort to exclude it from ever being introduced, we have partnered with CDFA and industry to aggressively prevent and eradicate the pest

UNLOCK OIL NUTRIENTS TO MAXIMIZE YOUR ROI Viewed as the fourth major nutrient, sulphur maximizes the uptake of other key nutrients – including nitrogen and phosphorus – that are critical for maximum yields and better returns on growers’ soil fertility investment. In fact, for each pound of sulphur deficiency, 15 pounds of nitrogen is lost through leaching and volatilization. To avoid sulphur deficiencies – and the loss of other vital macro and micro nutrients – apply premium sulphur fertilizer, TIGER XP™. Its unique composition, with a proprietary activator, helps increase nitrogen and phosphorus uptake and accelerate plant sulphate availability throughout the entire growing season.

Ruben Arroyo “The openness of the PCAs and the support of CAPCA to listen and express their concerns has been both beneficial and crucial to me making important decisions.” that could potentially introduce the disease and transmit HLB.” Similar efforts are underway to target GWSS. Efforts to eradicate or limit the spread of invasive species involve continual cooperation with Federal, State and local agencies, and industry partners. “We participate in cooperative pest prevention and exclusion programs with the USDA, CDFA, industry and other counties.” Challenges specific to the Agricultural Commissioner include understanding the delicate balance between encouraging commerce and enforcing regulations in an ever-changing food and agriculture industry. In Kern County, one of those delicate balances Mr. Arroyo works to maintain is the urban expansion into rural countryside. This creates development pressure at the urban fringe, increasing the importance of agricultural preservation but demanding special attention for the protection of people and the environment. “There is also a constant and relentless pressure to maintain adequate funding for my department. How do we utilize limited resources with increasing service demands?

CAPCA ADVISER | APRIL 2017

How can the department continue to minimize net cost to the County while avoiding overburdening industry/ stakeholders with fees that they may see as unreasonable?” There are many challenges, but significant rewards as well. When asked, Mr. Arroyo responded, “A highlight for me has been my privilege to be able to reach out to staff and all stakeholders and communicate with them: being involved, available, and responsive. Affecting successful outcomes through collaboration, strategic orientation and awareness. If I have achieved any level of success, then I believe it has been through my collaborative efforts with Federal, State and County governments to develop a positive working relationship with the agricultural industry, elected officials, environmental groups, and state partners. It has allowed me to achieve a solid history of ‘Protecting and Promoting Agriculture’ locally and internationally but with a firm and fair regulatory enforcement philosophy.” These also include successful programs at the local level like Spray Safe, Kern Red, and the Kern Schools Notification Pilot Program (for

As a reminder, Mr. Arroyo concluded with “I encourage all CAPCA members to visit your local Ag Commissioner and introduce yourself and get to know them. I have been blessed with so many great PCAs in Kern County and rely on their expertise to help understand the local history or chemistry. I would not be able to do my job without them!” T Editor’s Note: Ruben is moving to assume the duties of Agricultural Commissioner in Riverside County. He wishes to extend his gratitude to the Kern County PCAs and industry members for their support.

Protassium+ provides almond trees with readily available sulfate sulfur. Without the 17% sulfate sulfur found in Protassium+, orchards will lack the sulfur needed to produce top yields 2.

MORE TO OFFER Protassium+ is available in a wide variety of grades to provide application flexibility to any almond operation: • Granular • Soluble Powders • Certified Organic Powders • Premixed Liquid

THE PROTASSIUM+ DIFFERENCE Protassium+ nourishes almond orchards with high potassium and sulfate sulfur to promote greater nutrient uptake and better nut setting.

Invasive Shot Hole Borer Road Show Ariana Zamora, So. CA CAPCA Representative

APCA ED hosted an Invasive Shot Hole Borer (SHB) Road Show in January in Ventura and Temecula. The two continuing education meetings hosted over 250 attendees, including 162 Department of Pesticide Regulation license/ certificate holders, 82 certified arborists and two dozen Certified Crop Advisers. Researchers from UC Riverside and UC Cooperative Extension gave updates on the invasive pest, control measures and pesticides studies. Dr. Richard Stouthamer’s presentation provided an overview of the identification and origins of the different species of SHB in Southern California. The basic biology and lifecycle of the beetles as well as information on trap and lure combinations and possible biocontrol agents were also discussed. UC Riverside’s, Dr. Akif Eskalen covered several studies on SHB and Fusarium Dieback Disease. He provided an update on the current known host list of the invasive SHB and information on the efficacy of fungicide treatments and possible biological control strategies. He also presented current information on the epidemiology of the beetle infestations in avocado groves. Dr. Frank Byrne of UC Riverside focused on pesticide studies for the control of invasive SHB in avocado. His presentation covered current information on pesticide controls and data from lab and field studies of different pesticides. Control strategies in avocado and other host species were presented by Dr. Tim Paine of UC Riverside. He reviewed data on effects of chipping and solarization for the control of SHB in infested

wood. Dr. Paine also discussed data on pesticide applications useful in landscape and other non-agricultural settings. Since SHB isn’t just an issue in avocados, Dr. John Kabashima of UC Cooperative Extension presented an update of urban landscape management of SHB. He updated attendees on large scale landscape control trials for shot hole borers that have been taking place in Orange County in cooperation with UC Irvine and OC Parks Department. The road show is part of a Specialty Crop Grant funded by the California Department of Food & Agriculture. The grant is allowing CAPCA to host the continuing education seminars as well as short informational videos to build our citrus and subtropical crop team outreach. T

Damage Reduction by up to 50% Proven Possible Using Patented Sunburn and Heat Stress Protection Products Field studies show ongoing success using Surround® and Purshade® Protectants By Kurt Volker, Ph.D. You can’t control sunlight and high temperatures, but a pair of patented products from NovaSource can help make your plants more productive by minimizing UV damage from sunlight and heat stress that can rob both quality and yield. Growers in California and throughout the west are managing fruit, nut, and vegetable crops to deliver optimum quality and yields by using SURROUND Crop Protectant and PURSHADE Solar Protectant. SURROUND is a wettable powder formulation made from a highly engineered natural mineral – calcined kaolin clay. PURSHADE – a flowable formulation – is made from natural calcium carbonate. Both have superior light-reflective properties that shield plants from harmful solar radiation. When sprayed on plants, both SURROUND and PURSHADE lower leaf temperatures, enhancing plant photosynthesis and boosting overall plant health by enabling plants to remain more photosynthetically active during periods of intense light and heat. Both products help plants use water more effectively – which is not the same as saving water – during periods of intense heat and light because cooler plants make better use of water. Numerous field studies indicate that a coating of SURROUND or PURSHADE – applied directly to sunburn-susceptible fruits, nuts and vegetables – protects them from excessive heat and UV radiation, reducing sunburn damage by up to 50 percent.

Another benefit among the unique properties of calcined kaolin in SURROUND is it delivers the added protection of suppressing some insects. Additionally, SURROUND is OMRI approved and recommended for use in certified organic production operations for many crops. Surround was developed in conjunction with the U.S. Department of Agriculture. Both products are non-toxic. If a visible film is present at harvest, removal may be necessary for cosmetic reasons. In California and throughout the west, growers are increasing their yields of heat sensitive varieties by spraying the products two to three times during growing periods with the most intense sun and heat.

Special to the Adviser

Pest Control Through Plant Nutrition II: Calcium By: JW Lemons, CCA, CPAg Field Agronomy Manager, AgroLiquid

n the February issue of the CAPCA Adviser, we discussed potassium and how it aids in the challenge of feeding an ever-increasing population. Mineral plant nutrition has a critical role in integrated pest management. Almost every primary, secondary and micro nutrient can play a major role in the plantâ&#x20AC;&#x2122;s ability to develop primary pest resistance. Agriculture faces environmental pressure to find ways to reduce the amount of pesticides we use. Mineral plant nutrition can provide a significant tool for Pest Control Advisers. Pests can develop resistance to important pest control chemicals. It is up to us as Advisers to try to extend the life of such chemicals. In this article we will discuss calcium, one more nutrient key to the plantâ&#x20AC;&#x2122;s own defense mechanism to reduce pest pressure. Potassium is considered a primary nutrient. Therefore, I decided to discuss calcium as it is considered a secondary nutrient. In no way is it less important in the growth and health of a plant. Calcium is essential in cell wall development. It has also been found that calcium helps develop calcium oxalate crystals in some plants. Data presented in research clearly shows calcium oxalate contributes as an effective defense against chewing insects. Some larvae can detect its presence and simply avoid leaf tissue containing calcium oxalate crystals. The striking abrasive effect that the crystals have on insect mandibles suggests it deters the insects by physical means.1 Because calcium is immobile in the phloem, calciumbased fertilizers are widely used by the orchard industry to reduce calcium-deficient fruit disorders such as bitter pit of apples, and cork spot of pears. However, there is also a growing body of evidence noting that enhanced calcium concentrations in leaf, stem, and root tissue by calcium fertilization can aid in reducing pathogen severity caused by several fungi and bacteria. Calcium also inhibits the production of pathogenic enzymes that dissolve plant tissues.2 Results of one recent study have shown that there are significant differences in the fertilizer effect of calcium and the controlling efficacy of both Oriental fruit flies and red scale insects when treated with Nano particles. 28

CAPCA ADVISER | APRIL 2017

Furthermore, Nano-calcium carbonate could protect fruit from the oviposition of Oriental fruit flies. As plant protection agents, calcium carbonate particles are relatively safe and friendly for human and environmental use as compared with chemical pesticides. Another advantage of calcium particles is the lower resistance possibility. Oriental fruit flies, as well as other tephritid flies, have shown resistance against various recently used insecticides including organophosphate, pyrethroids, and spinosad. Of the two Ca particles in the study, Nano-Ca showed better performance in fertilization, plant protection, and pest control over colloidal Ca. Once more we see plant nutrition can play the dual role of feeding and protecting the crop. We will continue to bring additional nutrients to the forefront of their role in pest control. With continuing concerns and environmental pressure, the PCA needs to understand these tools. In their standalone role as a pest deterrent, or as a supplement to existing pest control materials, mineral nutrition plays a valuable role in plant disease and pest resistance. It can also extend the length of efficacy of pest control chemicals by extending their life before pests gain resistance to our current crop protection chemicals. T 1

journals.plos.org/plosone/article?id=10.1371/journal.pone.0141982

Pertinent examples include enhanced resistance against soft rot of potato caused by Erwinia carotovora subsp. Amylovora (McGuire and Kelman 1984; McGuire and Kelman 1986; Bain et al. 1996), Phoma exigua (gangrene) and Fusarium solani (dry rot) of potato (Olsson 1998), Botrytis cinerea of apple (Conway et al. 1991), sweet cherries (Ippolito et al. 2005), and brown rot of peach caused by Monilinia fructicola (Elmer et al. 2006). Recent research also indicates the form of calcium is potentially important for disease suppression (Elmer et al. 2006). For example, calcium nitrate reduced the incidence of brown rot of cherries in two of a three-year trial while calcium chloride forms had no effect on brown rot incidence (Wojcik 2001). Commercially, a wide range of calcium fertilizers exists to include calcium nitrate, calcium sulfate, calcium chloride, etc. Now findings from recent Nano technology have shown promise. 2

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

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

WEEDS RESISTANT TO GLYPHOSATE

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

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

UC IPM

A Practical Solution to Address the Emergence of Citrus Greening Forecasting in California Alireza Pourreza, Assistant CE Advisor, Kearney Agricultural Research & Extension Center and Affiliated IPM Advisor, UC Statewide IPM Program

alifornia is the major producer of fresh market citrus in the U.S., a $2 billion industry that is threatened by a devastating disease called citrus greening or Huanglongbing (HLB). HLB is a bacterial disease, psyllid vectored, and is known as the most dangerous citrus disease. Unfortunately, there is no cure for this disease and if a tree gets infected, it will die in a few years. All commercial varieties of citrus are susceptible to HLB. In Florida, HLB was first seen in 2005, but it spread rapidly across the state after a few years. Today, about 60% of Florida citrus has been destroyed, mostly due to a lack of an efficient HLB monitoring system. Just as one HLBaffected tree in Florida caused a statewide disease spread within a few years, one undetected HLB-affected tree in California can cause the same disaster. In the current monitoring practice, California Department of Food and Agriculture (CDFA) personnel or other agents are conducting inspections and samplings in commercial groves and residential areas. However, human based inspection is subjective and can be affected by external factors. Additionally, HLB diagnosis using laboratorybased methods are expensive and time/effort consuming. An efficient HLB management needs a high spatial and temporal resolution monitoring followed by eradication of infected trees. Therefore, a diagnosis sensor is needed to improve and facilitate HLB detection, especially before the development of symptoms. For high resolution monitoring, the sensor should also be able to conduct rapid and inexpensive inspection with high accuracy. The Asian citrus psyllid (ACP: the vector carrying the HLB bacterium) is widespread in southern California and now is distributing in the Central Valley. Since the first HLB-affected tree was identified in the Los Angeles area in 2012, many other infected trees have been seen in

Figure 1: The polarized imaging system developed for the detection of citrus Huanglongbing disease. LED=light-emitting diodes

the neighboring area. The HLB threat in California needs to be addressed immediately and HLB must be properly managed before it becomes as pervasive as in Florida. In an optimized HLB management, the disease monitoring scope should be expanded so that more citrus trees could be monitored. Also disease monitoring should be repeated in short-time intervals to improve the temporal resolution of the monitoring practice. If the citrus producers have access to this high temporal and spatial resolution data, they can significantly improve their decision making.

CAPCA ADVISER | APRIL 2017

HLB Detection Methodology Not only is HLB incurable, but it also has a long latent period that makes it even harder to control and manage. Starch accumulates greatly in HLB-affected leaves (Etxeberria et al., 2009), but it remains invisible for months or even years. When starch accumulation becomes visible, it presents a blotchy mottle on the infected leaf, that might be confused with some nutrient deficiency symptoms. Starch is capable of rotating the polarization of light (Pourreza et al., 2014). A sensing methodology (polarized imaging) was developed based on this optical characteristic of starch at the University of Florida. The sensor was able to detect the HLB-affected trees from healthy, and nutrient deficient trees (Pourreza et al., 2015). The sensor included an inexpensive, but highly sensitive monochrome camera, a set of narrow band high power light-emitting diodes (LEDs), polarizing filters, and a housing (Fig. 1). The total cost of sensor components was less that $1,000. Figure 2 shows that the polarized images captured from citrus canopies in different HLB/zinc-deficiency states, had different image intensities and contrasts. This finding can be more clearly observed in Figure 3 that shows the scatter plot of citrus sample images based on their gray valuesâ&#x20AC;&#x2122; means and standard deviations. A field test in Florida showed that the polarized imaging method could successfully reveal the HLB status of citrus canopies with 97% accuracy (Pourreza et al., 2015).

Early HLB Diagnosis The polarized imaging technique was also tested for presymptomatic HLB detection. Citrus trees (2-years old) were graft-inoculated using the disk-graft technique (Fig. 4). Time-lapse polarized images were acquired from leaves in a weekly manner to investigate how early (after the inoculation) the disease can be detected by the polarized imaging technique. Figure 5 shows the time-lapse images of a leaf from an inoculated citrus tree, acquired during a six-week period. The starch accumulation appeared five weeks after inoculation in the polarized images (on the mid-right side of the main vein) while the tree was in a nonsymptomatic stage and no visible symptoms were detectable. One important impact of using a real-time sensor is an improvement in HLB management by providing high temporal and spatial resolution maps of the spread of the disease in both commercial groves and residential areas. Improved management will lead to sustainable citrus production and the prevention of revenue loss in the California citrus industry. Growers can use the sensor in various ways (aerial, ground, or handheld sensing) based on their preferences and available equipment.

Wonsuk Lee and Reza Ehsani (University of Florida) and Dr. Eran Raveh (ARO Gilat Research Center, Negev, Israel) for their contributions in the development of the polarized imaging methodology.

COMMERCIAL GROWERS: Protect Your Groves from Huanglongbing (HLB) How to keep your trees healthy and productive for the long term. Take action to combat Asian citrus psyllid and HLB. » Start with preventive pest control. » Follow up with sequential pest treatments, as necessary, to eliminate Asian citrus psyllid populations.

The Asian citrus psyllid is continuing to spread through California and can easily spread between groves. Without monitoring, trees neighboring commercial groves could easily become hosts, bringing the pests and HLB into an otherwise healthy area. Help protect your grove and consider the Abandoned Citrus Tree (ACT) removal program, if necessary. The program is managed by California Citrus Mutual and allows growers to report abandoned trees that could threaten their groves.

» Educate your friends, family and neighbors about Asian citrus psyllid and Huanglongbing identification. » Be sure to report any abandoned trees that could threaten your groves.

Act Now Submit your information by visiting CitrusMatters.us. Once submitted, California Citrus Mutual will work with officials to review and discuss tree removal.

Introduction and Background ommercially grown citrus employs more than 22,000 individuals in California on about 3,900 farms statewide (Fig. 1). The incurable and fatal plant disease Huanglongbing (HLB), also known as citrus greening disease, threatens this $3.3 billion industry (CPDPP 2017). Huanglongbing affects all citrus plants, including orange, lemon, lime, mandarin, pummelo, kumquat, grapefruit and tangerine trees. It also affects some relatives of citrus in the family Rutaceae, some of which are occasionally grown as ornamentals. HLB is fatal for citrus trees and once a tree is infected, it will decline in health and eventually die. Bacteria in the candidate genus Candidatus Liberibacter are associated with trees infected with HLB. However, these bacteria have not been proven to actually cause the disease. Working with this pathosystem is difficult because it has not been possible to culture Cancidatus Liberibacter spp; the fact that they have not been cultured is the reason that the prefix Candidatus is affixed to the species binomials (BovĂŠ 2006). Two main species of C Liberibacter are associated with HLB world-wide. C L africanus is associated with HLB in Africa and portions of

CAPCA ADVISER | APRIL 2017

the Middle East, whereas C L asiaticus is associated with HLB in Asia and the New World. C L asiaticus is vectored by the Asian citrus psyllid (ACP) (Diaphorina citri), while C L africanus is vectored by different psyllid species, Trioza erytreae. Both psyllids can transmit both C L spp under experimental conditions; the association of vector and pathogen is due to geographic occurrence. Since C L asiaticus and D citri occur in the United States, the emphasis in the remainder of this article will be on these species. This tiny, mottled brown Asian citrus psyllid (ACP) is a sap-sucking, hemipteran bug from the Psyllidae family, that when it feeds injects a salivary toxin that stops elongation and causes malformation of leaves and shoots (Michaud 2004). The ACP takes C L asiaticus into its body when it feeds on HLB-infected plants. The disease spreads when a bacteria-carrying psyllid flies to a healthy plant and injects bacteria into it as it feeds (UC IPM Pest Notes 2017). Sometimes symptoms can look somewhat like zinc or other nutrient deficiencies and can be overlooked. However, the pattern of yellowing caused by nutrient deficiencies typically occurs symmetrically, between or along leaf veins. HLB infected leaves have an asymmetrical pattern of blotchy yellowing or mottling of the leaf, with patches

of green on one side of the leaf and yellow on the other side (UC IPM Pest Notes 2017). Diseased trees are meagerly foliated with small leaves that point upward, and the trees have extensive twig and limb dieback. Fruit are small, green, with dry interiors, and are not marketable. In due course, the tree stops bearing fruit and dies. Fruit and vegetative symptoms may not begin to appear for two or more years after the bacteria infect a tree. HLB can kill a citrus tree in five years, and there is no known cure. ACP was first discovered in the United States in June 1998 in Palm Beach County, Florida, on backyard plantings of orange jessamine (Murraya paniculata) (Fig. 2). By 2001, the ACP had spread to 31 counties in Florida, primarily due to the movement of ACP-infested nursery plants. By 2005, HLB was found in all commercial citrus orchards in that state. Agriculture officials believe HLB was present in Florida in backyard citrus trees, and the psyllid rapidly spread the disease to other backyards and commercial citrus not long after the psyllid arrived in the state. In 2001, ACP spread to the Rio Grande Valley in Texas on nursery stock and was also detected in Louisiana. The insect then spread to other states, and is now found in Alabama, Georgia, Mississippi, South Carolina, Arizona, and Hawaii, as well as Mexico (UC IPM Pest Notes 2017).

Current ACP and HLB status in California In 2008, the ACP expanded its range, likely from Mexico, to Southern California, where the insect was first detected in San Diego and Imperial Counties and soon thereafter in Los Angeles County. Throughout the years, it spread particularly in urban and suburban environments, but also in commercial groves. The psyllid has since expanded its range to the San Joaquin Valley and the Central Coast, and has also been found as far north as the Bay Area and Sacramento. The first detection of HLB in California was in a backyard tree in Hacienda Heights, Los Angeles County, in 2012. In 2015 and 2016, multiple incidences of the disease were found in San Gabriel, also in Los Angeles County. A total of 30 diseased citrus trees have been detected and removed, all in residential properties within Los Angeles County. The California Department of Food and Agriculture (CDFA) detected the most recent case of HLB in an orange tree in a residential area of Cerritos, Orange County, on December 29, 2016. Earlier that month ACP were collected from a

nearby property and tested positive for HLB. Agriculture officials quickly set to work to identify any infected trees in the area and the infected citrus tree in Cerritos was removed and all citrus trees within an 800- meter area were treated. In Mexico, the State of Baja California is adjacent to the southern border of California. HLB was detected in Ensenada, BC, early 2016 (CDFA 2016). In addition, on August 26, 2016 a tree also tested positive for HLB 23 miles south of the U.S.-Mexico border in a small citrus grove in Mexicali, BC. Now that HLB has been detected in Mexicali, Ensenada and in Orange and Los Angeles Counties, Southern California commercial citrus growers and residents who have any citrus growing in their back yard must remain vigilant. How to protect your citrus Trees Inspect trees for the presence of ACP and symptoms of HLB. Use a hand lens to look for small yellow eggs, psyllid nymphs with their waxy tubules, and adults. Immature stages (eggs and nymphs) are limited to tender new leaves and they donâ&#x20AC;&#x2122;t fly. Look for the characteristic

APRIL 2017 | CAPCA ADVISER

“blotchy mottle” or “yellow shoot” symptoms and report them to the County Agricultural Commissioner. Keep nursery protective structures maintained (Fig. 3). Don’t move citrus trees or propagative material into or out of your quarantined area. Fruit must be free of vegetative material and commercial fruit has additional requirements (see section below). Buy citrus trees from licensed, local nurseries and only use registered budwood. Cooperate with government and agriculture officials (CDFA, USDA, UC, and CPDPP) as they may ask to place yellow sticky traps in your residence or grove for monitoring and continue to participate in areawide coordinated treatments. The program also includes recurrent testing of psyllids and leaf samples for the presence of HLB. Results from these activities are being used to define quarantine zones, guide releases of biological control agents, and prioritize areas for a residential chemical control program. A tiny wasp from Asia called Tamarixia radiata naturally preys on the ACP, which prevents psyllids from spreading unrestrained. Researchers are currently exploring the effectiveness of another beneficial insect called Diaphorencyrtus aligarhensis to assist Tamarixia with control of the Asian citrus psyllid. To see where Tamarixia and Diaphorencyrtus have been released, visit this University of California’s website map and turn on the parasite layers: http://ucanr.edu/sites/ACP/. There is a fairly new initiative by California Citrus Mutual and Bayer CropScience to stop the spread of the ACP. The high cost of water and prolonged drought conditions have caused many rural homeowners to stop irrigating their trees. However, dead and dying citrus trees can still be a host for ACP and HLB (Fig. 4). The programs aims to help homeowners help their citrus grower neighbors by removing uncared for or abandoned trees at no cost. To date, over 400 abandoned citrus trees have been removed from residential properties in Tulare and Ventura counties. Growers and homeowners can report abandoned trees online using a confidential web form at www.citrusmatters.us. Qualifying properties are located near commercial citrus groves and in an area where psyllids or HLB are present. Bulk Citrus Compliance Agreement Enforcement began on March 1, 2017 for the new Bulk Citrus Compliance Agreement, a new statewide regulation requirement that restricts the movement of regulated articles from “or within” a quarantine area. Under the new regulation, all bulk citrus loads must be safeguarded regardless of their origin or destination. This can be done in several ways, including but not limited to the use of a shipping container, tarp, enclosed vehicle, including curtain van, or another method that completely covers bulk citrus during transport. Tarps or mesh coverings must not have holes larger than 0.3 square millimeters, which is the standard tarping requirement per the USDA. It is important to note that standard tarping methods have

CAPCA ADVISER | APRIL 2017

not changed. Bulk citrus must also be declared “ACP free,” either by chemical treatment or field cleaning vegetative material from fruit. Penalties for non-compliance may be assessed by the state or county and can include fines as high as $10,000 per violation, and potentially also include revocation of the compliance agreement. If you did not receive a revised compliance agreement in the mail, please contact the program at (916) 403-6848. Additional resources may become available – check CitrusInsider.org regularly. The future of California’s Citrus HLB has spread throughout Florida and citrus trees are dying at alarming rates. Thousands of jobs have been lost and the economy is suffering. Florida growers are doing everything they can to save their citrus trees, but researchers have not yet found a long-term solution to the disease. Florida agriculture officials believe HLB was present in backyard citrus trees, and the psyllid rapidly spread the disease to other backyards and commercial citrus not long after the psyllid arrived in 1998. That is why in order to combat HLB in California, we must learn from Florida’s situation, the industry needs to be willing to make decisions and invest in actions that will protect both conventional and organic groves and include neighboring neighborhood communities. We must work together for the livelihood of growers, pickers, packers and haulers are all at stake.

Palmageddon: The Invasion of California by the South American Palm Weevil is Underway

Fig. 1

By Mark S. Hoddle and Christina D. Hoddle, Department of Entomology, University of California, Riverside

n December 2010, the South American palm weevil (SAPW), Rhynchophorus palmarum (Coleoptera: Curculionidae) (Fig. 1), was found in association with dying Canary Islands date palms in Tijuana Mexico. Adult weevils are large, about 1.25 inches in length, and SAPW is now the largest weevil found in California. Weevil larvae (Fig. 2) feed in the crown of palms killing the apical growing region. This feeding causes fronds to fall from palms, and eventually the crown will drop leaving a halo of dying mature fronds encircling the top of the palm trunk (Fig.3). Larvae form fibrous cocoons within which they pupate. Often these cocoons are tightly wedged within tunnels excavated by pre-pupal larvae at the base of the frond (Fig. 4). When infestations are particularly heavy, cocoons may litter the ground beneath affected palms (Fig. 5). Opened cocoons may reveal larvae getting ready to pupate (Fig. 6), pupae, or unemerged adult weevils. Economic Impact The potential economic damage in California from SAPW is significant. For example, it is estimated that Californiaâ&#x20AC;&#x2122;s ornamental palm industry is worth ~$70 million each year. Some estimates suggest that each 12-inch length of trunk of a Canary Islands date palm transplant is worth $500. The installation of a mature date palm in the

FARM ADVISORS urban landscape may cost as much as $5,000 per palm. In addition to ornamental palms, the California date industry, with an estimated value of $68 million per year, is also vulnerable to SAPW. And what is the value of iconic native California fan palms, Washingtonia filifera, inhabiting desert oases? These desert-dwelling palms may also be attacked by SAPW. The impact of SAPW on palms in California may eventually be amplified by a palm-killing nematode, the red ring nematode, Bursaphelenchus cocophilus, which causes red ring disease, a lethal malady of palms. SAPW vectors this nematode, but it has not yet been recorded in California. Over the next few years, we expect SAPW will continue to spread in California, and we are anticipating significant levels of palm mortality, especially to Canary Island date palms growing in urban residential areas, public and private recreational zones where palms are common landscaping features, and in wilderness areas where palms have naturalized (e.g., river washes in San Diego County). Removal of palms killed by SAPW is an expensive and technically difficult procedure (Figs. 7-8). The Response to SAPW Detections In response to the discovery of this notorious palm pest in Tijuana in December 2010, the California Department of Food and Agriculture (CDFA) initiated a monitoring program in southern California in 2011 to delineate the newly infested area. Palm weevil monitoring is straight-forward and utilizes a bucket trap baited with fermenting fruit (e.g., pineapple chunks or dates in water mixed with bakerâ&#x20AC;&#x2122;s yeast) which is held in a separate container with a perforated lid that is placed inside the bucket trap, commercially-available SAPW aggregation pheromone, and a synergist, ethyl-acetate, both of which are suspended from the bucket lid (Fig. 9). The combination of volatile odors from fermenting fruit, pheromone, and ethyl acetate is highly attractive to SAPW adults. Typically the bucket trap is wrapped with burlap to help adult weevils attracted to the trap to crawl up the sides of the trap and through windows cut in the bucket from which they drop into a preservative (e.g., propylene glycol) (Fig. 10). Traps are suspended above the ground to minimize animal interference (Fig. 11). The CDFA trapping program detected SAPW in San Ysidro in San Diego County in May 2011. Captured weevils Fig. 7 had likely originated in Tijuana and flown the ~3 miles

to the traps. This is probably an easy distance for SAPW to fly. CDH has accumulated flight distance data using computerized flight mills in the laboratory that indicates SAPW is capable of flying tens of miles in a 24 hour period should it elect to do so. The take home message from these lab studies is that SAPW is a very strong flyer and capable of dispersing long distances without human assistance (e.g., accidental movement into new areas inside infested palms). During the two year life span of the trapping program, CDFA caught 111 SAPW until the program ceased operating in 2013 because of a lack of funding. Trapping programs in Texas and Arizona caught SAPW in 2012 and 2015, respectively. It is unknown if SAPW has established in these two states. Beginning in May 2016, concern over SAPW activity grew because of reports of increasing numbers of dead palms in Tijuana that had died because of SAPW attack. A casual 8 hour driving survey around Tijuana in May 2016 resulted in the recording of about 140 dead Canary Islands date palms (Fig. 12). Dead desiccated palms are a significant fire risk in Tijuana as several Fig. 10 home owners described incidences of dead palms combusting as a result of sparks that originated from overhanging powerlines. Heavy weevil attack to fronds of some palms was also evident in Tijuana (Fig. 13). Around this time, reports of dead Canary Islands date palms were made from San Ysidro in San Diego County and cause of mortality was subsequently assigned to SAPW. Beginning in June 2016, surveys around southern San Diego County were undertaken by MSH and CDH in an attempt to determine how widespread SAPW was in southern California. Weekend driving trips through areas with high invasion potential and the running down of leads emailed or called in from concerned citizens quickly led to the conclusion that SAPW had established in San Diego County from San Ysidro north to Chula Vista. At this time it is unknown how far west, east, and north of Chula Vista populations of SAPW may be. The reason for this uncertainty is due largely to a lack of financial support to develop a monitoring Fig. 11 and management program for this pest. Also, because of the widespread distribution of SAPW in San Diego County, and the probable existence of high density populations in infested areas, it is unlikely that this pest can be eradicated from California as was achieved recently with another invasive palm weevil, Rhynchophorus vulneratus, in Laguna Beach (Hoddle et al. 2017). Containment and control programs, should they be initiated in San Diego County, may have their efficacy reduced if simultaneous programs targeting SAPW populations in Tijuana are not undertaken. Control Options There are currently no recommended control programs for managing SAPW infestations in California palms. However, experience with the management of other closely related palm Fig. 12

Fig. 13

weevils, like the extremely invasive and destructive red palm weevil (RPW), R. ferrugineus, indicate that a combination of management practices are needed. These programs are insecticide intensive and usually incorporate a contact pesticide applied to palm foliage, especially the central crown region that target adult weevils and simultaneous application of systemic insecticides that are translocated within the palm to kill larvae. Some arborists cut “windows” into the palm crown and the removal of these fronds permits visual inspection of this highly sensitive area for weevil activity. In addition to pesticides, bucket traps loaded with bait and pheromone and the removal and destruction of infested palms have resulted in programs that have significantly suppressed RPW in date plantations in the Middle East (Hoddle et al. 2013). In Spain and other Mediterranean countries with active RPW infestations, numerous iconic Canary island date palms that have significant “heritage” value are outfitted with a permanently affixed shower head positioned over the palm crown. Pipe is attached to the palm trunk through which pesticide is pumped and it exits the shower head “showering” the palm crown with insecticide. Biological control options for SAPW may exist, and one potential natural enemy of interest is a parasitic fly, Billaea rhynchophorae (Diptera: Tachinidae), from South America that is reported to attack SAPW larvae and pupae. Little is known about the biology and ecology of this fly or the population-level impacts it may have on SAPW (Löhr 2013). A major concern over running a classical biological control program targeting SAPW in California is safety, in particular, the host specificity of potential weevil parasitoids. The risk of attacks to non-target weevil species, especially native California weevils (and potentially other species of native US weevils), by a SAPW natural enemy from South America may be unacceptable. Another anticipated difficulty would be the mass rearing of SAPW and non-target weevil species for host specificity and host range studies in quarantine; establishing and maintaining colonies of target and non-target weevil species will likely be challenging and very expensive. The Way Forward In response to the obvious threat posed by SAPW to California’s palms, UC Riverside, UC Cooperative Extension, CDFA, the San Diego County Agricultural Commissioner’s Office, and San Diego Parks and Recreation with financial support from the Western Regional IPM Center, held a one day meeting in October 2016 to inform concerned parties about the extent of the SAPW invasion in southern California. From this meeting, a list of management, research, and extension needs were developed largely with input from meeting attendees. These identified priorities are being used to develop grants to solicit funding to commence work on SAPW. The need to respond to the SAPW invasion is obvious, the expertise to develop strategies to manage SAPW in California is available,

CAPCA ADVISER | APRIL 2017

and with the procurement of financial support, program development can commence. Obtaining funding in 2017 is a major goal for the incipient SAPW program – so please stay tuned, we anticipate having more to report on this highly destructive palm pest in the near future.

Putting Biopesticides to Work in the Field

Jeremy Briscoe, Western Regional Sales Director, Certis USA

oday’s PCAs need to provide growers with viable pesticide alternatives, resistant pest management and early-entry harvest solutions with lowto-zero pesticide residues for market flexibility and export accessibility. Biopesticides help us meet those challenges on conventionally grown acres, as well as organic. More than 90 percent of biopesticide usage is on conventionally produced crops. As the crop protection industry loses certain chemistries that we’ve always relied on to control insects and pathogens, we still need to protect the crop. The biopesticide industry has provided products to fill that void both with efficacy, safety and ultimately profitability. Biopesticides help Hector Mariscal do a better job for his clients. Mariscal is the PCA/CCA owner and operator of Devan, Inc. His company protects caneberries and strawberries in the Salinas and Watsonville production areas for both conventional and organic operations. “Biopesticides are a key component in our ever-growing requirements to comply with laws and regulations that protect cities, counties, schools and the environment,” Mariscal says. Additionally, biopesticides help him provide his grower customers with export flexibility, safety, tank-mixing flexibility and are an element in overall good crop health. Export Flexibility “One of the main reasons we use them,” Mariscal says, “is that they don’t limit export shipments to key, strategic places around the world.” A maximum residue level (MRL) is the level of pesticide residue that is legally allowed in or on food or feed by an importing country. Most biopesticides are residue exempt, therefore their use does not increase the residue tally. This makes the crops they treat available for export to more countries. The result is more marketplace flexibility for growers.

Gina Colfer, PCA/CCA and key account manager for organics for Wilbur-Ellis in Salinas, agrees. “Most biopesticides have a four-hour reentry interval and a zero-day preharvest interval. If you have an issue close to harvest, you won’t have a problem with using a microbial too close to harvest. You don’t have to worry about MRLs. “If you have a harvest foreman needing a close-to-harvest insecticide or fungicide, a biopesticide is a good option,” Colfer says. Safety Mariscal says it is important to him that biopesticides offer a high degree of safety for workers, growers and the environment. Colfer says, “Most have caution signals, so they are the lowest in toxicity. Worker safety is first and foremost. For bees, they keep our pollinators safe, and also for our waterways. Some of our chemistries are under the gun for threatening our waterways.” Plants, too, are safe when most biopesticides are used. “They are pretty safe for the plant,” explains Colfer, who points out that most biopesticies are not phytotoxic to crops. Tank-Mix Flexibility Mariscal believes that biopesticides are the ideal tank-mix partner. They can be used to extend

the control of pests during a season and help preserve the useful life of synthetic pesticides by helping to hold resistance at bay through the use of their unique mode of actions. “When we have a long season, like 12 months,” Mariscal says, “we’re limited on the quantities or rates per acre of the pesticides we can use. We can introduce a biopesticide at a more frequent rate throughout the season to help us combat disease.” Mariscal adds, “On conventional fields where I spray conventional materials for powdery mildew, I may not get full control. Biopesticides help us reduce the development of disease resistance.” Biopesticides bring different and more complex modes of action to the table. There are a myriad of types of biopesticides, including beneficial bacteria, fungi, nematodes, protozoa, viruses and yeasts. These biological active ingredients use different modes of action that, when used in a tank mix with synthetic chemistries, can help delay the development of resistance. Biopesticide mode of actions are often multi-site and novel when compared to chemical mode of actions. They may include the release of metabolites to kill pathogens by disrupting cell membranes and cell walls (Bacillus amyloliquefaciens), activating induced resistance by the plant (Bacillus mycoides isolate J) or viral infection of a specific insect (Cydia pomonella granulovirus).

Using Biopesticides Mariscal is a strong proponent of biopesticides, appreciating the additional tools they provide him. But he stresses the need to work with the materials: “You have to understand how the biopesticides work. Understand how they function and then you can strategically place them in your pest management programs.” Mariscal educates his growers that using any pesticide on a preventive basis will be more costefficient and effective. Colfer agrees: “You have to know your pest target when using these materials. It’s also important to use them as preventives rather than curatives. You don’t want the pest population to get so high that you are already behind when you introduce your microbial. If there’s a major outbreak, the microbials can’t catch up as well. “Start early and then reapply in short intervals, say seven to 14 days to re-inoculate the leaves,” Colfer says. “Relative humidity is important. If it’s a dry environment, you might need a shorter interval. “If used properly, they can be efficacious,” she says. “Timing is critical. Know your target pest. Do proper evaluations. And don’t give up on using them. It’s just a matter of finding out where their fit is in your programs.” T

The Importance of Adjuvants in Herbicide Applications

Spray adjuvants from Helena give applicators an edge in the evolving battle against hard-to-control weeds. odern weed management requires a precision operation. It M is crucial to determine the correct tank mix while providing an application environment that gives herbicides a chance to work to their full potential. Many application issues that can hinder herbicide performance are addressed by spray adjuvants from Helena Chemical Company such as Contingent, Dyne-Amic and Smoke. Contingent is a specialized blend of methylated seed oils and surfactants designed exclusively for burndown, dessication and industrial weed control applications. It is designed to perform under adverse conditions, offers quicker initial weed control and superior uptake compared to conventional MSO and COC products. Contingent is also compatible with all glyphosate formulations. Dyne-Amic is an effective blend of highly refined methylated seed oils in combination with specialized organosilicone-based nonionic surfactants. With low phytotoxicity qualities, it is much easier on crops than conventional crop oil concentrates. The oil component of DyneAmic provides excellent penetration, while the surfactant provides highly effective spreading and coverage. Smoke is a herbicide activator that enhances herbicide efficiency with a blend of deposition agents, activators and water conditioners. It improves spray deposition and uptake, while preventing antagonisms caused by poor water quality. Originally designed for use with glyphosate, Smoke can be used with other herbicides, insecticides, fungicides and foliar nutritionals. Plus, it can conveniently replace the need for pre-mixes of AMS and surfactants. For application recommendations and to find the right adjuvant for your operation, contact your local Helena representative. Learn more at helenachemical.com, featuring more information on Helena products and services.

WORMS, THRIPS, LEAFMINERS

IN ONE PASS

Only Radiant® insecticide controls worms, thrips and leafminers. And university trials in Arizona and California show that Radiant outperforms other commonly-used vegetable insecticides on all three of these pests. As a member of the spinosyn class of chemistry (IRAC Group 5), Radiant controls pests like no other class of chemistry used in vegetables. The Re-Entry Interval is only 4 hours, and the Pre-Harvest Interval is 1 day for most crops.
