Nutrient Management & Efficiency Technologies

Sure, markets are tough but growers are tougher. They’ve got a business to run and they want to get every last dime out of their fertilizer investment. Help them out by recommending AVAIL® Phosphorus Fertilizer Enhancer. No matter how much phosphorus is applied, AVAIL makes P uptake more efficient and that means a better ROI. vlsci.com | 800.868.6446

From the Editor CAPCA’s Leadership Institute Plan

ll successful Ag Leadership programs start somewhere; would you be part of launching CAPCA’s? Two weeks ago I watched veteran PCA and Desert Valleys Chapter member Art Anderson receive a lifetime leadership award from Project CENTRL in Arizona. Art was part of their successful Ag Leadership program pilot Class I in 1983. It made me wonder what leaders we would see awarded 35 years from now under the CAPCA Leadership Institute. The Membership Survey in 2015 confirmed once again that the majority of PCAs continue to grow closer to retirement - a third of current CAPCA members reported they are planning to retire in the next five years. CAPCA sees a huge wave of Agrarian Impact Award goes to Art Anderson, Class I industry knowledge leaving that needs to be captured immediately by establishing a venue to share the knowledge and experiences of industry leaders poised for retirement with the new generation of PCA leaders. This is one of the main purposes of the Leadership Institute. As we develop pilot programs for Leadership Institute, we are simultaneously finalizing an application for non-industry funding. We plan to run regional programs across the state at reduced cost, but we need membership to demonstrate industry support (via completed 100B surveys) to secure this funding. This is where we have hit the biggest road block. Members and Sustaining Members alike will benefit from this type of professional leadership development within CAPCA, and I believe that reduced cost leadership training for the PCA in all stages of their career will be a win for the industry and another way we can express to policy makers the high bar of professionalism PCAs aspire to reach. If you are willing to show industry support, interested in participating in the leadership program as an attendee, or even contributing as an experienced PCA, please email me at ruthann@capca.com. Our first pilot programs are slated to run later this summer, and we would like to have all completed survey forms returned by September 1st. The CAPCA staff looks forward to using the Leadership Institute as another way to serve our membership. #wedomorethantrackhours Ruthann Anderson, Editor ruthann@capca.com

LEADERSHIP

CAPCA Leadership Update

ere we are in the second year of transition since the retirement of our CEO Terry Stark. I am pleased to report that CAPCA is stable and moving forward with our new CEO, Ruthann Anderson, who has been on the job since the start of 2016. One of the current issues we struggle with is finding common ground with our regulators. Prior to our May Board meeting the CAPCA Exec Committee and Government Relations Chair Henry Buckwalter and Past Chair Gary Silveria met with DPR leadership to discuss current issues that our respective organizations are facing. Both of our organizations recently experienced some turnover. As a result, CAPCA has experienced some difficulties with our CE submittals for CAPCA ED seminars and our upcoming Annual Conference. Discussion revolved around changes at DPR and how we can move our industry forward, enhance professionalism and improve our knowledge while being compliant with AB 2122. DPR made it clear that to receive accredited CEUs the speaker descriptions must include verbiage as to how the topic relates to Pest Management or Pesticides. Ruthann and staff are maintaining a regular dialogue with DPR to address this issue. The most significant event of the May Board meeting was the approval to hire a firm to rebrand CAPCA and update our website. The changes will allow more streamlined access to CAPCA, its committees,

our Conference, CAPCA ED, SWS, Leadership Institute, Pathway to PCA and other programs. It will also allow better access and benefits to chapters. For example, a chapter member will be able to sign up for Chapter CE and pay with credit card through the website. In addition, members will be able to sign up for multiple events at the same time and add items to a “cart," then checkout. As the Crop Teams and new Public Relations Committee evolve, it will also allow a clean platform to disseminate information and messaging. As Mother Teresa said “I can do things you cannot do, you can do things I cannot, together we can do great things.” As CAPCA members it is important to remember our purpose: to serve as the leader in the evolution of the pest management industry through the communication of reliable information. From the perspective of an arborist who performs plant health care services, it is easy to see the importance of recommendations provided by Pest Control Advisers. Especially, when those recommendations are for no application. During my years at Cal Poly, our license was promoted heavily as IPM practitioners. Most of the PCAs I know practice IPM. It has become evident that our licensor does not recognize us as IPM practitioners. Therefore, it is up to us to raise our level of professionalism and continue to educate ourselves. And like Mark Twain said, “Do the right thing, it will gratify some people and astonish the rest.” T

CAPCA ED Collaboration Meetings By Mindy DeRohan and Ariana Zamora

APCA ED co-sponsored a continuing education seminar with University of California Division of Agriculture and Natural Resources (UC ANR) in Palm Desert on June 9, 2016. More than 90 people attended the seminar which was comprised of California Department of Pesticide license and certificate holders, Arborists, Certified Crop Advisers and Master Gardeners. Janet Hartin, Environmental Horticultural Advisor for Riverside, Los Angeles and San Bernardino Counties, presented on the “Impact of Drought and Other Abiotic Disorders on Pathogens.” Hartin discussed the implications of under and over irrigation of landscape plants and trees, and the relationship to pests including bark beetles, Phytophthora and other disorders. Consequences of the drought include a greater incidence of both biotic and abiotic disorders impacting many species of landscape plants. Donald R. Hodel, Environmental Horticulturalist for Los Angeles County gave a presentation on “Common Palm Disorders in the Coachella Valley.” He covered common disorders and diseases of palms. The talk also covered best management practices to prevent diseases, both through cultural practices and pesticide use. The Riverside County Agricultural Commissioner’s Office gave a Regulatory Update, comprised of county registration renewal requirements, updates on personal protective equipment and common violations seen by county inspectors. James Bethke, Farm Advisor of San Diego County rounded out the program with “Common Insect Pests of Desert Ornamentals.” Bethke spoke about the importance of IPM in the landscape and gave examples of insects and control methods. Some of the insects mentioned were South American Palm Weevil, Coconut Rhinoceros Beetle, Polyphagous Shothole Borer and Gold Spotted Oak Borer. This is the first CAPCA ED meeting outside of the Organic/Sustainable Production Seminars and CCA Nutrient Management Seminars where the CAPCA ED team collaborated to provide attendees with a unique perspective on regional pest control. Because of the positive feedback received from the meeting, CAPCA ED is working with UCCE to host a meeting at the Los Angeles Arboretum in November 2016. This type of collaboration and partnership brings added value to the CAPCA ED program and the meeting attendees. The CAPCA ED staff looks forward to building even more collaboration efforts with organizations throughout the state. If you have any questions or would like to collaborate with CAPCA ED, please contact Mindy DeRohan, Ariana Zamora or Jackie Tabarez. T

PCA PROFILE

“I have had the greatest pleasure meeting and knowing the men and women who comprise the agricultural industry.”

Mark Allen:

Promoting the Professionalism of the PCA Mindy DeRohan, CAPCA ED Manager

by Mindy DeRohan, CAPCA ED Manager

ark Allen has been involved in production agriculture for more than 11 years. He received his PCA license in 2009 and specializes in pollination management and plant pathology. The major crops that he consults in are walnuts, almonds, grapes and small grains. Mark earned his B.S. degree in Horticulture from Cal Poly, Pomona with a minor in Pest Management. In addition to his PCA license, Mark also holds a QAL and is a past board member of the California State Beekeepers Association. A territory manager with Nufarm, Americas for three years, Mark is responsible for technical sales and support of Nufarm Americas’ large product portfolio in Northern California and Oregon. He works with PCAs, crop consultants and farmers to assist in improving harvestable yields. Nufarm Americas is consistently developing new products and new labeled uses for existing materials. Part of Mark's job is listening to the needs of clients, matching the best tools, and educating clients on the labeled uses and timing. Before joining the Nufarm Americas team, Mark worked for Marrone Bio Innovations as the regional sales manager for Northern California and the greater Pacific Northwest. Mark also worked for 16 years in pollination and beekeeping throughout Northern and Southern California.

CAPCA ADVISER | AUGUST 2016

To keep improving his own professionalism, Mark participates in education and training. He believes that self-improvement is a never-ending process and taking an active role in the industry, in addition to his day job, is the best way to grow as a professional. Mark also relies on the UC Extension, UC IPM, or the Oregon State Extension for reliable information. His favorite part about being a PCA is working with the variety of crops, cropping systems, landscapes and finished products. Mark said, “no other profession allows for such vast and eclectic working environments.” Not coming from a strong agricultural background, Mark was motivated to become a PCA from the hands-on education that he received at Cal Poly, Pomona. “Learn by doing is the Cal Poly way and my professors allowed this system of structured information and trial-and-error in the field. The practical field instruction seemed to lead directly into the practical field approach of a PCA.” Mark said the biggest highlight of his career has been working with the people. “I have had the greatest pleasure meeting and knowing the men and women who comprise the agricultural industry.” When asked about his most challenging pest management experience, Mark replied it is working to educate the public about the true use of pest management.

ADVERTORIAL

Plan for Early Hull Split Sprays in Pistachios to Manage NOW Warm spring and rapidly mounting degree days could help pests get an early start.

nother mild winter and warmer-than-average spring on the West Coast means degree-day units are building at a rapid rate, and, with them, the potential for heavy pressures from pests such as navel orangeworm (NOW). An earlier start for the pests could also mean an extra NOW generation this season.

“When it comes to determining the best time to spray, crop development stages and pest pressure should always trump degree days.”

In many parts of California, development of this year’s pistachio crop is ahead of the normal pace — as much as two weeks in some areas, says Jeff Pacheco, DuPont Crop Protection technical sales agronomist. “In orchards with heavy NOW pressure, protecting pistachios as early as pea-split may be critical to preserving nut quality. And it’s better to err on the side of caution and make the first application a little early than a little late with newer insecticides.”

With the threat of a possible fourth NOW generation, growers seeing higher pest pressures should consider a fourth spray timed between the 3,000 and 3,200 degree-day accumulation points, says Pacheco. “Later sprays are important for producers using two-shake harvesting, which can put some of the crop at greater risk for lateseason damage.”

DuPont™ Altacor® insect control powered by Rynaxypyr® is a good first-spray option because its duration of activity provides some application flexibility, he adds. “Altacor® provides long residual, ovicidal,1 ovi-larvicidal, larvicidal and adult activity2,3 on navel orangeworm and is an important part of an effective NOW management program.”

Resistance management is an important element of an effective integrated pest control program and especially important with NOW. As more acres of pistachio trees come into production, the increase in tree nut acres is leading to increased pest pressures, says Pacheco. “We’ve already seen some types of insecticides, such as pyrethroids, become less effective against NOW following multiple applications during the season.

Track Key Degree-Day Points Research conducted by entomologist Joel Siegel, USDA San Joaquin Valley Agricultural Sciences Center, Parlier, California, has identified four important times to intensify scouting and make insecticide applications if needed — 1,700, 2,200, 2,700 and 3,000 to 3,200 degree days (starting from January 1). “These peak flight times for navel orangeworm in pistachios are good guidelines, since an effective application should be made before peak egg laying of NOW” says Pacheco. “Based on these degree-day points, the first application may need to be made a little earlier than normal in some orchards due to crop phenology. That’s certainly a possibility this season.” Start scouting trees early, he recommends. “When it comes to determining the best time to spray, crop development stages and pest pressure should always trump degree days.” The first application should help to knock down the early NOW population and prevent a pest buildup, he says. “Second and third sprays that coincide roughly with 2,200 and 2,700 degree-day points might also need to be made a little earlier depending on pressure, climate conditions and days to harvest.”

Manage Against Insect Resistance

“It’s important to avoid treating successive NOW generations with the same insecticide or insecticides with the same IRAC group number,” he says. “Altacor®, an anthranilic diamide (Group 28) insecticide, fits well into a rotational program, providing longlasting control of NOW and only a 10-day preharvest interval.”

Altacor® a Good Fit for Pistachios Lasting, effective control and an excellent environmental profile make DuPont™ Altacor ® insect control a valuable option for protecting pistachio crops. Key benefits include: • Exceptional control of lepidopteran pests, including navel orangeworm and peach twig borer • Flexible application timing • Short four-hour re-entry interval • Minimal impact on beneficials • Excellent spray-tank stability under a wide range of pH levels

Significant ovicidal activity is observed at varying levels depending on pest species. Activity is maximized when eggs are laid onto treated surfaces. Disruption of adult insect behaviors in some pest species is observed (e.g., codling moth, oriental fruit moth), such as mate finding, mating, oviposition, feeding, locomotion and orientation. 3 Adult mortality is species, application rate, exposure level and time dependent for NOW (based on lab and field studies).

Residential and commercial areas are ever expanding and encroaching into all production areas throughout the state. “Our greatest challenge is the same need for communication of the facts and public relations to media sources and local events outside of our direct industry.” Mark believes that resistant weeds, both ALS resistance and other direct target site resistance, pose the most problems to clients and growers. Resistant weeds affect both agricultural and professional industries that PCAs manage day to day. “Many optional chemistries are developed for our staple crops within the heartland of the nation, but virtually all of those resistant weed varieties are found and confirmed here in California. Weed management does not always get the same attention as insect management, but the effect these resistant weeds play on yields is significant. Best management practices are in place to assist in battling these weed problems. New materials and more affordable options continue to replace

CAPCA ADVISER | AUGUST 2016

older chemistries and practices.” Huang-Long Bing (HLB), also known as citrus greening, is a bacterial disease vectored by the citrus psyllid that is currently destroying much of the citrus industry in Florida and has been detected in sections throughout southern California. Mark believes this is the pest of greatest concern for the industry. “CDFA has done a good job of managing and excluding this psyllid from our main citrus production areas. However, there have been new finds reported closer to production areas periodically and with the extensive amount of backyard citrus in the greater Los Angeles area, eradication programs are hard to facilitate, if not impossible. In Florida, eradication of the citrus psyllid is still the most important management practice, but new tools are now targeting protection of the tree from bacterial infection in addition to psyllid eradication programs. Within the last few years in California there has been confirmation of HLB infected trees in two different areas of Los Angeles County. All known traces of infected material has been quickly removed, but the necessity for continued vigilance is critical.” Mark believes that IPM is considering all technologies available to target and control specific pests with the least negative effects on the people and the environment. “IPM is the implementation of common sense into the control products and practices for a given situation,” Mark said. When asked if his clients are using genetically altered crops or cutting-edge technologies, Mark replied, “Most of the tree nut, vegetable, and vine crops in the California area are not directly affected by genetically modified technologies, outside of marketing concerns. However, our diverse state includes virtually all important crops grown in the United States, including

genetically developed varieties. New technologies are on the horizon and are currently being approved that includes many different tools for growers to move away from just over-the-top glyphosate use and into a diversity of options that promise less intensive spray applications. These genetic technologies could be a strong partner in IPM programs we are all seeking in the field.” Mark is working diligently to get more CAPCA members involved in local activities. “As the Woodland Chapter president, I am working with our fellow chapter members to invite new and existing CAPCA members to join in the chapter discussions and activities. One of those activities this summer is a tour of our local brewery in Woodland who source ingredients from local farms. These networking activities allow for a meet and greet opportunity outside of our label update and organic production meetings held at other times of the year.” Mark encourages all PCAs to be involved in CAPCA because of the wide range of work that CAPCA does to ensure the professionalism of the PCA: “CAPCA works to support the industry and interests of the licensed California Pest Control Adviser in preparation for issues that negatively affect farmers and the ability to protect their crops. Whether this is from proposed/pending Federal and State programs or from education needs for the public and interest groups, CAPCA helps to provide knowledge and communication between different interest groups to the practical challenges and needs of production agriculture. I would like CAPCA to continue playing an active role in the next issue, regulatory or pest challenge, and communicate to our PCAs the additional resources that are put toward their interests.” T

CAPCA recently received several notes from California FFA students expressing appreciation for our support. CAPCA is a proud sponsor of the Agricultural Sales Entrepreneurship Proficiency competition, the Agricultural Services Proficiency competition, and the Agricultural Pest Control contest in California. The Ag Sales Entrepreneurship Proficiency competition recognizes students who own and operate a sales business. The Ag Services Proficiency competition recognizes students who work for or own a service business related to agriculture. We have previously featured the Ag Pests contest, which rewards students for identifying a variety of agricultural pests and the crops they damage.

State Champion FFA Ag Pests Team from Tulelake High School L to R: Mackenzie Winters, Kaitlin Hartung , Alejandra Gonzalez, Melissa Martinez and Trevor Autry, State FFA Officer presenting the awards.

he State Champion Ag Pests team from Tulelake High School worked hard to earn their title from a great group of competitive teams. To be successful in this contest, each team member must learn to identify a wide variety of agricultural pests. They also must be able to speak about the pests to a judge and identify the crop that the pest damages and how they make that damage. These students are learning skills in high school that will be of great help to them in the future if they seek a career in crop protection.

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.

IPM of Spider Mites in Almonds: Exploring the New Sampling Techniques

Jhalendra Rijal, North San Joaquin Valley Area IPM Advisor, UC Statewide IPM Program and UCCE Stanislaus County

pider mites are one of the major arthropod pests sampling can estimate the overwintering mite population in almonds in California. There are three species in the soil. If there is a relationship of the overwintered of webspinning spider mites (Pacific spider mite, population with the seasonal population infesting tree Tetranychus pacificus; twospotted spider mite, Tetranychus leaves, soil sampling may be useful as an early prediction urticae; and strawberry spider mite, Tetranychus turkestani) method of what future mite populations can look like that can cause economic damage in almonds during in the orchard. Also, finding ways to trap mites on tree the growing season (Zalom et al., 2012).

However, more research needs to and protection from natural enemies (Gerson, 1985; be done to refine these techniques and see how we may be Kennedy and Smitley, 1985). In the beginning, damage able to use this in population estimation. by spider mite feeding results in stippled leaves, which We started some preliminary work focusing on advances to yellowing and dropping of leaves as the the development of the early-detection method of mite infestation progresses (Andrews and La PrĂŠ, 1979).

Rijal This might have been due to changing environmental conditions (e.g., relatively dry seasons), lack of early monitoring tools for overwintering mites, prophylactic application of miticides, and frequent use of broadspectrum insecticides particularly pyrethroids (Zalom et al., 2001), , resulting in flare ups in the mite population in summer and fall. Spider mites overwinter on the orchard floor and move to the trees as the season progresses in the spring. Currently, we only know mite presence or infestation after we see their damage on leaves (leaf stippling) in spring or later. Winter soil 30

Mites emerged from the soil, moved and stuck on the cards. Those mites were counted after two weeks. We recovered an average of 0.85, 1.00 and 0.75 mites per 6 oz soil sample from front, middle and end sampling areas, respectively. Although mite seasonal population is known to vary within the orchard, we did not observe a statistical difference (ANOVA; F = 0.66; P = 0.538) on average mite counts among three sampling areas. This might have been due to the uniformity in terms of environmental conditions such as soil moisture, tree health and other factors among sampling areas. Results are presented in Figure 2. We will be taking in-season leaf samples from those trees to evaluate the mite population in the trees as well. Since the results are preliminary, we will expand these studies in more sites in coming seasons for the conclusive results. We are also performing some preliminary studies on the use of tree-band traps (Fig. 3) on the trunk (about 3-4 feet high in the tree). The trap consists of an inner circular layer of paper towel, which is overlapped by a band of duct tape 6 inches wide. A sticky material (tree insect barrier product) was smeared over the tape so that mites will be trapped while they are migrating to the leaves in trees. We placed these traps on the trunk and the biggest limb of the almond trees in early March and removed them in late May. We have recovered more than one species of spider mites, and are in the process of identification. Future plans include testing these sampling techniques in orchards that have high mite pressure. We will compare the infestation of mites on leaves with and without bands. This provides information about the effectiveness of the bands in monitoring female mites as well as excluding them from foliage. In addition, knowing the ground-to-tree movement timing can be useful in controlling mites in a different way, such as by applying a barrier treatment on the trunk. In the long-run, these methods may be helpful in planning spider mite management. T

Control of Hairy Fleabane with Saflufenacil Can Vary by Season and Growth Stage

Figure 1. Hairy fleabane infestation in an almond orchard (Photo: Kurt Hembree)

Michelle Dennisa, Anil Shresthab, Kurt Hembreec, John Bushovenb a California Dept. of Food and Agriculture, Sacramento b Dept. of Plant Science, California State University, Fresno c University of California Cooperative Extension, Fresno Abstract: Experiments were conducted in fall and spring at Fresno, CA to determine the efficacy of glyphosate, saflufenacil, and a tank-mixture of saflufenacil + glyphosate on glyphosatesusceptible (GS), glyphosate-resistant (GR), and glyphosateparaquat-resistant (GPR) biotypes of hairy fleabane (Conyza bonariensis) at various growth stages (5- to 8-leaf seedling, rosette, and bolting). Seasonal effects were noticed in the control of the hairy fleabane plants with the selected herbicides. All GS, GR and GPR plants were controlled by saflufenacil-alone up through the rosette stage, but control declined at the bolting stage. Saflufenacil-alone was more effective in the fall than in the spring, but control with saflufenacil + glyphosate was excellent during both seasons. Glyphosate-alone provided good control of all three biotypes at the 5- to 8-leaf stage in the fall, but control was poor in spring. Therefore, saflufenacil-alone can provide excellent control of hairy fleabane prior to 32

the bolting stage in the fall; but in spring, it will be more effective when tank-mixed with glyphosate.

Introduction: airy fleabane (Conyz bonariensis) remains a problematic weed in California even after several years of research (Figure 1). Although this weed has been present in the state for decades, it gained more prominence after the discovery of a glyphosate-resistant (GR) biotypes in 2008 and subsequently a glyphosate and paraquat resistant (GPR) biotype in 2010. Glufosinate was identified as an immediate alternative for successful control of these herbicide-resistant biotypes but research has continued to identify other herbicide modes of action and management strategies for a good resistance management plan. One herbicide introduced fairly recently in California is saflufenacil, a protoporphyrinogen oxidase (PPO) inhibiting herbicide. Saflufenacil has been registered for postemergence control of broadleaf weeds in citrus, nuts, and pome fruits. Several studies have shown that glyphosate was more effective when sprayed during cooler parts of the year (Moretti et al., 2013) and control was affected by the

Figure 2. Control of hairy fleabane treated at the 5- to 8-leaf stage by the various herbicide treatments in Fall and Spring [(saflufenacil 1x = 1 oz/ac; glyphosate 28 fl oz/ac; saflufenacil (1oz/ac) + glyphosate (28 fl oz/ac); GS = glyphosate-susceptible, GR = glyphosate-resistant, GPR = glyphosate+paraquat resistant].

growth stage of the plant (Shrestha et al.). Therefore, we wanted to evaluate if the efficacy of saflufenacil on GR, GPR, and glyphosate-susceptible (GS) hairy fleabane was also affected by season and growth stage. Methods: The experiments were conducted at California State University, Fresno, CA. Seeds from previously confirmed GR, GS, and GPS were used for the study. Plants grown in pots from these seeds were treated at the 5- to 8-leaf stage, rosette stage, and initial bolting with 0.25x, 0.5x, 1x, and 2x of saflufenacil (where x = 1 oz/ac), 28 fl oz/ac of glyphosate and a tank-mixture of 28 fl oz/ac of glyphosate + 1 oz/ac of saflufenacil. A surfactant, methylated seed soil (MSO) 1% v/v, was added to the saflufenacil

treatments. Ammonium sulfate was added to all herbicide applications at the rate of 2% w/v as recommended by the label. An untreated control treatment was also included. Each treatment was replicated five times and the experiment was conducted in fall and spring. Herbicide spray volume was 40 gallons per acre. The plants were evaluated for mortality periodically and finally at 30 days after treatment (DAT). Results: Applications at 5- to 8-leaf stage of hairy fleabane Control of 5- to 8-leaf stage hairy fleabane plants with the various herbicide treatments was influenced by the season (Figure 2). Better control of all three biotypes (GR, GS, and GPR) of hairy fleabane were obtained in AUGUST 2016 | CAPCA ADVISER

Figure 4. Control of hairy fleabane plants treated at the bolting stage by the various herbicide treatments in Fall and Spring [(saflufenacil 1x = 1 oz/ac; glyphosate 28 fl oz/ac; saflufenacil (1oz/ac) + glyphosate (28 fl oz/ac); GS = glyphosate-susceptible, GR = glyphosate-resistant, GPR = glyphosate+paraquat resistant].

the Fall with all the herbicide treatments. Saflufenacil was effective even at lower doses in Fall. However, it is advisable to use label rates as lower rates can select for herbicide resistance. It was interesting to note that glyphosate was even effective against GR biotypes in Fall. On the contrary, in the Spring, the label rate of saflufenacil did not provide adequate control and the label rate of glyphosate provided good control of only the GS plants. However, the tank-mix treatment of saflufenacil and glyphosate provided 100% control of all three biotypes. Applications at the rosette stage of hairy fleabane Similar to the 5- to 8-leaf stage, control of hairy fleabane plants with the various herbicide treatments was also influenced by the season (Figure 3). The results were very similar to that of the 5- to 8-leaf stage plants in Fall. However, in the Spring even the tank-mix treatment of saflufenacil and glyphosate was not as effective against the GR and GPR biotypes and only controlled GS plants. Applications at the bolting stage of hairy fleabane Unlike at the earlier growth stages, control of hairy fleabane was generally poor in both seasons when the applications were made at the bolting stage (Figure 4). Higher than label rates of saflufenacil provided some control of the GR and GS plants but no control was obtained of the GPR plants. Similarly, in Spring, only the GS biotype was controlled to some extent with the tankmix or the glyphosate-alone treatment.

CAPCA ADVISER | AUGUST 2016

In conclusion, the efficacy of saflufenacil on hairy fleabane can be affected by the season. In the Fall, saflufenacil alone at the label rate may provide good control of all three biotypes of hairy fleabane provided the applications are made at or prior to the rosette stage. In the Spring, it may be advisable to apply a tank-mix of saflufenacil + glyphosate prior to the rosette stage because during this season inconsistent control may be obtained on bigger hairy fleabane plants.

Soil Moisture Monitoring Soil Moisture Monitoring

Water plays a signicant role in crop producƟon. Adequate and Ɵmely irrigaƟons are essenƟal to excellent crop yield. Soil acts as a reservoir for water storage. Over-irrigaƟng leads to increased energy and water costs, increased potenƟal for leaching of valuable plant nutrients, and longer periods of saturaƟon limiƟng crop growth. Likewise, under-irrigaƟon may be detrimental to plant growth because it limits transpiraƟon and nutrient uptake, thereby placing the crop under stress. ConƟnuous soil moisture monitoring allows you to observe each irrigaƟon event and what happens in between. You see how deep the moisture moves based on how much you apply. You can also observe the depleƟon of water through evapo-transpiraƟon. As that soil moisture curve begins to aƩen out, you know the crop is working harder to extract more water. You will want to schedule the next irrigaƟon prior to reaching the rell point to avoid placing the crop under drought stress.

WHAT NOAA’S OFFICIAL “LA NIÑA WATCH” MAY MEAN FOR CALIFORNIA PRODUCERS How fertility choices impact 2016 performance and profits Producers in the state are on high-alert when it comes to weather pattern predictions since experiencing the most severe drought in nearly 120 years of record. After four years of subnormal precipitation and above normal temperatures during the wet season, a domino effect has begun to occur in the state. This is due in part to the La Niña effect, which is a slight tilt towards dryness during the wintertime. This year, a strong El Niño brought some relief, with extra moisture from the Pacific. However, now that California is in an ENSO-neutral period (where neither El Niño nor its sister, La Niña is present) producers are looking to what will happen next.

What will it take to end the drought? David Miskus, senior meteorologist and lead drought contact at the Climate Prediction Center, explains that California needs several years of above-average precipitation and seasonable temperatures to end the drought. “If the winter temperatures are too mild, the precipitation would fall as rain in higher elevations, eating away at any snow in the mountains,” says Miskus. “This is okay for filling reservoirs and rivers, but it can hurt the spring snow melt and ultimately not impact drought conditions. For chances at removing or greatly improving long-term drought conditions, California is in need of several years of close to above-normal winter precipitation – including the Sierra Nevada snowpack and seasonable temperatures.”

Specialty crops are hypersensitive to high chloride In 2016’s June update, the National Oceanic and Atmospheric Administration (NOAA) announced a 70% probability of La Niña occurring this winter, meaning the drought will likely continue based on historical weather data. If that’s the case, challenging growing conditions will continue for California’s specialty crops, such as tree nuts, fruits and vegetables, which are especially sensitive to high

levels of chloride. Without water to leach the already-present chloride from the soil, extended drought periods result in a profusion of concentrated chloride. Build-up of chloride in a plant's root structure blocks the uptake of essential nutrients that are critical for crop health and growth.

Protassium+ — The K source solution While growers can’t control the rainfall, they can choose fertilizers that do not contribute to increased chloride levels in the soil, such as Protassium+TM sulfate of potash from Compass Minerals®. Protassium+ has less than 1% chloride and the lowest salt index per unit of K2O of all major sources of potash. With virtually no chloride, Protassium+ gives crops an advantage, especially in areas with drought challenges, highly saline soils, or poor quality irrigation water. These conditions make Protassium+ sulfate of potash ideal for California growers looking to protect crop performance and profits.

Summer and Fall Management of “Super Broadleaf Weeds” in Tree and Vine Crops By Pedro Hernandez As the residual efficacy of winter and spring applied preemergence herbicides in tree and vine crops begin to break in summer, you can see the emergence of weeds that are no longer being controlled by these treatments. It is at this point you should begin to think about how to control these “escaped” weeds. Some of the most common broadleaf weeds that are difficult to control in the summer and fall in tree, nut, and vine crops include: Field bindweed, Purslane, Malva, Lambsquarters, Silverleaf nightshade, Russian thistle, Alkali weed, Marestail, and Fleabane. These weeds are “super broadleaf weeds” because they grow and multiply aggressively and are resistant or tolerant to some pre- and postemergence herbicides. It is important to control these weeds not only because they compete with the crop for water and nutrients, but they can interfere with irrigation and harvest and serve to replenish the weed seed-bank. These weeds are difficult to control because they emerge after preemergence herbicides have lost their residual activity or the staple herbicides such as glyphosate, paraquat, or glufosinate are just not as effective as standalone treatments. Growers and PCAs are aware of the herbicide resistance or reduced susceptibility of these weeds to staple postemergence herbicides; therefore, many of them opt to treat with tank mixtures of contact herbicides with different modes of action to combat development of resistance. There are a number of postemergence contact herbicides that can be used to effectively manage these weeds. An excellent choice is VENUE® Herbicide from Nichino America. VENUE is a burndown PPO (Herbicide Group 14) broadleaf herbicide, which has been successfully integrated as part of a complete weed management program. VENUE is typically used in combination with glyphosate, glufosinate, or paraquat to broaden the weed control spectrum of the application, combat development of resistance, and improve the speed of control. Some of the weeds on which VENUE has proven to improve the efficacy of the application include: Field bindweed, Alkali weed, Stinging nettle, Lambsquarters, Russian thistle, Malva, Silverleaf nightshade, Marestail, and Fleabane. The crop safety profile of VENUE allows for applications in bearing and nonbearing stone fruit, nut trees, grapes, and other TNV crops as early as 1 year old plantings. VENUE is a nonrestricted use pesticide, has no preemergence activity, and it does not volatilize. Because VENUE is a contact herbicide, spray coverage is very important in achieving maximum results. Nichino recommends 30 to 40 gallons of water per acre and the use of COC or MSO surfactant. The key to managing “Super Broadleaf Weeds” is to treat them as small in size as possible, apply with adequate spray volume to obtain good coverage, and use a combination of herbicides with different modes of action.

eNhance™ or Stabilize Nitrogen Nitrogen fertilizer is subject to losses due to volatilization, denitrification, and leaching. The severity of loss is often dependent on soil moisture, temperature, and the placement of nitrogen in the soil. Most liquid fertilizers contain three forms of nitrogen – urea ((NH2)2CO), ammonium (NH4+) and nitrate (NO3-). Most plants can utilize the ammonium and nitrate forms of nitrogen, although the biological processes in the soil work to convert nitrogen to the nitrate form. Nitrate is the most susceptible to loss through leaching.

NH3

NO3NH4surface waters

Most nitrogen “stabilizers” on the market today inhibit the biological processes in the soil that convert nitrogen into the nitrate form. Urease inhibitors, such as Agrotain® inhibit the enzyme urease that is produced by many soil bacteria, preventing the formation of ammonia (NH3). Nitrification inhibitors such as N-Serve®, eNtrench®, Agrotain®Plus and Instinct® inhibit the activity of the soil bacteria Nitrosomonas, preventing the conversion of NH4+ to NO3-.

eNhance or Stabilize Nitrogen In contrast, eNhance™ is a nutritional supplement that amends the urea and ammonium portions of UAN solutions to reduce the amount of ammonium converted to nitrate. That reduces volatility and denitrification, making nitrogen available to the plant as it is needed. eNhance™ also works within the plant to aid in nutrient transport, making other nutrients that enter the plant more efficient. Unlike traditional nitrogen stabilizers that inhibit biological activity in the soil, eNhance™ works within the plant, fortifying the crop’s physiology to more efficiently utilize applied nitrogen. Nitrogen stabilizers are used to prevent nitrogen loss so their use can be considered an insurance policy. If soil and environmental conditions are not conducive to nitrogen loss there would be no benefit to the addition of those stabilizers. However, eNhance™ improves the utilization of nitrogen in the plant and is not dependent on soil and environmental conditions. Adding eNhance™ to UAN solution allows the user to reduce the rate of fertilizer and maintain yields, or use the full rate of fertilizer and have the potential for higher yields than achieved by UAN without eNhance™.
