  • Help Needed: Identifying Telone Application Sites this Fall/Late Winter

    The Almond Alliance has been meeting with Department of Pesticide Regulation (DPR) on their initiated 1,3-D pilot programs in three areas of the state:  Shafter, Kern County; Parlier, Fresno County; Delhi, Merced County. The objective of the pilot programs is to evaluate growers and applicators with alternative methods of achieving emission reductions of 1,3-D comparable to tarping. DPR put forth 13 proposed mitigation measures including buffer zones, TIF tarping, soil moisture depth, water seals, amended injection depths and more.

    The Almond Alliance has been engaged in numerous discussions with DPR on this issue and has mobilized our membership to provide feedback and have detailed discussions on why several of the proposed options are not procedurally and economically feasible. We have been clear that our industry needs this fumigant for treatment of nematodes during the replanting of almond trees.

    In August of this year, the Almond Alliance submitted a detailed letter to DPR summarizing the almond industry’s concern about the proposed pilot options and why several should not be considered at all.  To review letter, CLICK HERE.

    DPR has asked that we identify 2 to 3 orchards to evaluate during replanting this fall/spring and will be applying Telone as a soil fumigant. Would you be willing to have your site be a part of an assessment of some fumigant off-gassing reduction measures that DPR would like to assess? If yes, or even if you think your site might not meet the DPR criteria, you should speak with the Almond Alliance and DPR. An ideal orchard is one with no other surrounding orchards, specifically upwind/downwind as DPR needs to have space for the equipment to measure what is emitted into the air.

    While some wanted DPR to move to additional regulation of Telone right away based on the air monitoring data, DPR decided to do some “pilot studies”, partially buying a bit of time. In the process, DPR realized that they needed additional field monitoring data on the off gassing of Telone under different conditions to improve their models, as well to assess the off-gassing if some new mitigation measures were employed. Thus, the hunt for appropriate sites with good grower cooperators.  However, if additional sites with growers willing to cooperate cannot be found, DPR will move forward regulating based on the limited data they already have. That will lead to a significant increase in locations where Telone cannot be used and/or only with the use expensive TIF tarps.

    The proposed emissions mitigation measures include:

    • Getting soil moisture in the top 6-9 inches to 70% water holding capacity as a water seal.
    • Injection the fumigant at 24-28 inches rather than at 18 inches.
    • Mixture of one of the above and strip TIF tarps.

    ​​​​​​​If your site meets the desired conditions – particularly no orchard immediately adjacent to the location and you are willing, we are asking that you discuss the possibility with your soil fumigant applicator company and contact Elaine Trevino at 209-300-7140.

  • Protecting your Almonds from Ant Damage

    Almonds sat on the ground to dry a little longer this season due to the abnormal drop in temperatures and increase in humidity at harvest. This provided a longer window of opportunity for ants to feast on the valuable product.  Regardless of what the future brings, there will always be ants in the orchard and now would be a good time to freshen up your knowledge on how to manage them in the orchard. Watch this interview with UC IPM Advisor Kris Tollerup and don’t miss his upcoming ant management presentation at the annual Tree & Vine Expo on November 10th.

  • Survey Asks Californians About Views on Agriculture

    In February 2020, the Grower Shipper Association of Central California (GSA) conducted a survey of residents in the Bay Area and in our local farming regions.  While this survey was conducted prior to the COVID-19 pandemic, the results and responses still have value and provide important information to GSA as we work to advance families, food and farming in our region.

    Among the most gratifying result was how much Northern Californians valued agriculture.  Seventy-seven percent stated that agriculture was most or very important to the quality of life and the economy of California.  “We were very pleased to see that so many residents recognized the important work of farmers and farm workers, even before the pandemic,” says Chris Valadez, GSA President.

    The survey shows residents also appear to understand some of the issues facing agriculture, including labor and potential shortages.  Seventy-seven percent of respondents supported the employment of guest workers by agriculture under the H-2A visa program to offset domestic labor shortages and 71% agreed guest worker programs are important to California’s economy.  However, 54% said they were concerned about the impact of guest workers on housing in the region, a concern shared by the agricultural community.

    “While new farm worker housing projects along the Central Coast are in process now, we must continue to work to find innovative solutions to ensure adequate and safe housing is a priority for our community,” Valadez says. “The pandemic further underscored the need for more affordable housing in our region.”

    Food safety is where survey respondents indicated they want agriculture to advance efforts to continuously improve and better protect public health. Respondents generally agreed they want farmers and government agencies to work jointly to improve food safety.

    The survey also explored views on water quality and water supply.  Almost 70% of respondents stated that their water quality was good to excellent.  And, seventy-eight percent agreed that their biggest water concern was an adequate supply and impacts from another drought.  While water was a less important issue among respondents overall, when probed, 64% of respondents stated that agricultural runoff was a concern.

    Finally the survey looked at residential, industrial and agricultural use of pesticides. Interestingly 42% of respondents said they understand the benefits of pesticide use with 23% stating they were unsure about those benefits. This may convey a need for agriculture to continue to provide more information about the safety standards and use of pesticides in organic and conventional production.

    Conclusions:  

    As it did for every one, the pandemic severely shifted the focus of the farming community and GSA.  Significant time and resources were devoted to protecting essential farm workers from COVID-19 exposure while working to ensure a consistent supply of safe and healthy foods reaches consumers.  As the pandemic evolves, GSA’s work to facilitate the availability of protective equipment for farm workers, in-field training by medical professionals, quarantined housing and adequate COVID-19 testing programs continues and remains of primary importance.

    However, the survey findings as well as conversations with media, residents, regulators, elected officials and labor groups throughout the pandemic show that Californians want and need more information about issues impacting agriculture and our industry’s response.  It is also clear respondents greatly value farming in California and its importance to a healthy economy.

    After examining the survey results, GSA’s focus will be on the continuance of solution-based programs, enhanced and transparent external communications about farming practices as well as continued dialogue and engagement with residents, elected officials, labor and environmental advocates.  This survey will help GSA prioritize its attention and efforts on the issues of key importance to Bay Area and Central Coast residents.

    GSA is preparing a white paper with complete survey results as well as a new webpage called “Our Work” which will provide information on these specific issues as well as GSA solution-based programs and activities.  The Our Work webpage will go live in the coming weeks.

    The online survey was conducted in eight counties in the Bay Area and Central Coast from February 7 through February 10.  The survey margin of error was 4.0. 

  • Grapevine Red Blotch Update from UC Davis Foundation Plant Services

    Foundation Plant Services (FPS) has been testing grapevines in its foundation vineyards for grapevine red blotch virus (GRBV) since 2013. Red blotch infection rates have remained extremely low in the Classic Foundation Vineyard, ranging from 0% to 0.21% since 2013. None of the 4,270 vines were infected in 2020 (see table). Russell Ranch Vineyard (RRV) remained unaffected until 2017 when five of 4,132 vines, only 0.1%, were infected with GRBV. Since then, despite significant efforts to prevent the occurrence of the disease, the infection rate in the vineyard has increased to 0.5% (24 of 4,406) in 2018, 7.1% (339 of 4,761) in 2019, and 18% (788 of 4,367) in 2020 (see table).

    Since the discovery of red blotch in the foundation vineyards, all propagated vines related to the positive vines tested negative in every case, indicating the incidence of red blotch at RRV is due to field transmission of GRBV. In addition, material from these plants was distributed prior to the last negative test date, suggesting that material was GRBV-free at the time of distribution. In 2018, we implemented a test-to-order policy that further ensure orders being shipped were negative just prior to distribution.

    One of the greatest challenges in managing red blotch has been vector-mediated transmission. The three-cornered alfalfa hopper, Spissistilus festinus, has been documented as a vector in greenhouse studies and has been found in RRV. Given this threat, we have implemented more frequent vineyard inspections and additional spray treatments specifically targeting the vector and developed a comprehensive program for control of this vector. However, it remains unknown if other vectors are involved in the transmission of red blotch. We are working closely with University of California scientists to monitor the foundation vineyards for potential vectors and track the spread of the virus.

    Given the level of red blotch infection in Russell Ranch Vineyard, we feel the best course of action is to discontinue distributing material from RRV. However, grapevine material from the Classic Foundation Vineyard, which represents the majority of clonal families from RRV, will continue to be available for distribution and is tested for GRBV as dormant canes prior to shipping.

    FPS is greatly committed to maintaining the highest testing standard for our foundation vineyards. We will continue to test all vines in the foundation vineyards individually on an annual basis and implement the best management strategies to safeguard foundation material. In addition, FPS has begun working

    with UC Davis planners to design a 24,000 square foot ‘Emergency Greenhouse’ that will protect approximately 4,000 of FPS’ most valued Foundation grapevines. This is essential to protect the material from vectors and guarantees immediate access to the clean plant material in case of field infection. FPS is currently renting two 1,100 sq ft greenhouses in the interim from the College of Agricultural and Environmental Sciences to temporarily house the most valuable clonal selections as newly propagated virus-tested mother vines in a protected environment.

    Moving forward, a collaborative approach between FPS and the grape industry is needed to protect grapevine Foundation material from exposure to viruses. Although there are major knowledge gaps about the transmission and epidemiology of grapevine red blotch virus, well-funded research teams around the country are working on elucidating the biology. In the meantime, FPS is moving forward to ensure protection of the core grape Foundation which is an essential asset to the US grape industry. — By Deborah Golino (FPS Director dagolino@ucdavis.edu) & Maher Al Rwahnih (Director of Laboratories malrwahnih@ucdavis.edu)

  • Fruit World Enters Citrus Season with New Sustainable Packaging and Increased Volume of Organic and Conventional Offerings

    Fruit World, a family-owned, flavor-focused grower-shipper of organic and conventional fruit, enters their 2020 citrus season with bold, new recyclable packaging and increased availability of 100% California-grown organic and conventional mandarins, along with organic oranges, grapefruit, lemons, and sweet limes.

  • $45 Million in Funding for Citrus Research Awarded

    A total of $45 million in funding for citrus research during the 2020-21 fiscal year was awarded by the United States Department of Agriculture National Institute of Food and Agriculture (USDA-NIFA) Emergency Citrus Disease Research and Extension (ECDRE) Program. The ECDRE Program addresses priorities identified by the Citrus Disease Sub-Committee of the National Agricultural Research, Education, Extension, and Economics (NAREEE) Advisory Board by sponsoring research projects designed to provide solutions to the U.S. citrus industry. For the 2020 fiscal year, the ECDRE program selected 12 projects to receive awards.

    With funding support from the Citrus Research Board (CRB), Pepsi Co and Coca-Cola, and a consortium led by the Citrus Research and Development Foundation (CRDF), NIFA awarded a $10 million grant for their on-going coordinated agricultural project with Bayer Crop Science. The project seeks to identify and develop therapeutics for HLB and the presumed HLB pathogen ‘Candidatus Liberibacter asiaticus’ (CLas). Researchers are investigating synthetic and microbial therapeutics for further characterization and optimization, intending to develop therapeutics for commercialization.

    According to the CRB President, Marcy Martin, “Success with this project will help all citrus growers, not just those from a particular state. We like that CRDF and CRB were able to team up on this worthy project.”

    Among this year’s awardees, three current and past CRB-funded California researchers from the University of California were awarded $12.5 million between three projects. CRB-funded researcher Chandrika Ramadugu, Ph.D., was awarded $4.7 million to lead efforts to evaluate novel citrus hybrids for tolerance/resistance to HLB in multi-state field trials in California, Texas, and Florida. Caroline Roper, Ph.D., received $6.5 million to unravel the underlying mechanisms of tree health in HLB impacted groves and develop a set of best practices for extending the life and productivity of citrus groves. Past-funded CRB researcher Yen-Wen Kuo, Ph.D., was awarded $1.41 million to explore utilizing insect-specific viruses to manipulate the Asian citrus psyllid (ACP) and its associated microbes to limit psyllid activity and disease spread potentially.

    CRB-funded researchers Vivian Irish, Ph.D., from Yale University, Anne Simon, Ph.D., from the University of Maryland, and Robert Shatters, Ph.D., from the USDA Agricultural Research Service also received awards. Irish is spearheading research with a $1.5 million award to identify HLB susceptibility genes in citrus, which will assist in future breeding efforts. Simon received $1.5 million to lead efforts to develop a phloem-restricted viral vector that could be used to directly target CLas in the phloem or modulate citrus host responses. Shatters has received $9.4 million to explore the development of an in-field therapeutic screening system with accompanying delivery systems. Past-funded CRB researcher Goutam Gupta, Ph.D., was awarded $4.8 million to lead efforts in developing novel therapies for the prophylactic and curative treatment of HLB.

    Additionally, researchers from the University of Florida and the University of Maryland received awards to study CLas, ACP and HLB strategies.

  • Fall Microirrigation System Maintenance

    California Avocado Commission — Microirrigation systems (microsprinklers, drip emitters and drip tape) tend to provide better distribution/emission uniformity than other irrigation methods. However, the miniscule flow passages in these systems can become clogged and thus disrupt the uniformity of water applied to a crop.

    Late fall and winter are an ideal time to review irrigation systems for needed repairs or malfunctions. A great resource is the University of California Division of Agriculture and Natural Resources’ (UCANR) webpage that outlines various causes of microirrigation clogging and means of preventing or mitigating the problems.

    The first step in alleviating clogs is identifying the problem. Clogs can be caused by:

    • Particulates — sand, silt, clay — from surface water sources
    • Biological materials — algae, bacterial slimes — from surface water sources
    • Chemical precipitates — such as iron and calcium carbonate — from groundwater sources or fertigation

    To identify the issues, UC ANR recommends first flushing water from the lateral lines through a nylon stocking or paint straining cloth and examining what material is collected. If you see mineral particles, you have identified your problem. If you notice that clogging tends to occur at the ends of the lines, this also tends to indicate particulate clogging.

    If you identify organic matter when flushing the line, then biological materials are the issue. You also can open the end of a lateral line and feel inside the tube to see if it is slimy. If so, biological materials are the source of your problem.

    If you note white, crusty materials or reddish staining of the soil near the emitters, this is indicative of chemical precipitates.

    Once you have identified the clogging source, you can take steps to address the issue.

    Particulate issues can be prevented by regular line flushing and the use of filters. UCANR provides a list of various filters and a table noting which filter to choose based on water source, particulates and irrigation system. To adequately flush the lines, water must flush at least 1 foot per second at the end of the drip line — 1 gallon/minute for 5/8” diameter and 2 gallons/minutes for 7/8” diameter drip lines.

    If organic matter is the source of the clogging, the best mode of treatment is a good filtration system combined with use of a biocide to remove the biological contaminants. Visit the UCANR site for a list of filters and the aforementioned “how to choose a filter” table.

    If calcium carbonate (lime) or iron is clogging your emitters, strong acid can make either disappear if emitters are left in it overnight. Lowering the pH (6 or below) of the water by injecting common acids — sulfuric acid, muriatic acid or hydrochloric acid — can help prevent clogging due to lime. UCANR provides specific formulas to help growers determine the injection rate needed to alter water pH.

    If high iron levels are the source of the clogging, aerating the water to oxidize the iron and then allowing the precipitates to settle before irrigating (a reservoir or settling basin is necessary) is the most practical option. Common acids also can be injected to decrease the pH of the water (4 or less).

    For more information on routine microirrigation tasks, visit the UCANR website.
