  • Adding ACP-Effective Materials to Suppress Kern County HLB Vectoring Pest in Citrus

    ACP/HLB San Joaquin Valley Task Force – To Citrus Growers in the Kern County area: last fall and early this year, there has been a significant number of Asian citrus psyllid (ACP) trap detections (over 100) in Kern County. The detections occurred in residential properties, as well as commercial citrus areas in Kern County – especially the City of Bakersfield and areas south and east of it. Unfortunately, in addition to the trap detections, live breeding populations of ACP were discovered by CDFA survey crews in both residential and commercial citrus. Although these detection areas were treated, there is significant concern low level ACP populations may still exist undetected and left to build on the new spring flush. It is imperative for us to continue our efforts to protect Kern County citrus from the devastating effects of Huanglongbing (HLB) – especially in light of the significant level of HLB-positive citrus trees found just south in Los Angeles, Orange, San Bernardino and Riverside counties. An established population of ACP increases the threat of HLB but will also cause the need for additional insecticide treatments to try to suppress the population. Additionally, if HLB is detected and confirmed by CDFA, critical regulatory changes may affect everyone. Given the posed risks, it is important the San Joaquin Valley keep ACP populations as close to eradicated as possible.

    The San Joaquin Valley ACP/HLB Area-Wide Task Force has been tracking and analyzing all ACP detections to date in Kern County. After recent review of the data, the Task Force strongly recommends growers add an ACP-effective material to their pre-bloom or spring foliar treatments – the sooner, the better since ACP build populations on the young leaf flush.  Fortunately, this timing coincides with pre-bloom treatments and treatments for katydid, worms, thrips and other pests.  See below for material examples from the University of California.

    IMPORTANT: If there is any open bloom in the orchard, state bloom regulations and pesticide label pollinator protections must be followed.  Contact the Kern County Agricultural Commissioner’s Office for details at (661) 868-6300.

    WHAT WE NEED YOU TO DO:

    1. Consider treating ALL your citrus blocks in Kern County, especially if they are located east and south of Bakersfield – including non-bearing trees and blocks not normally treated at this time.
    1. Use an ACP-effective insecticide next time you are treating the block. The sooner, the better – click on the link below for a list of ACP-effective insecticides from the University of California: Asian Citrus Psyllid / Citrus / Agriculture: Pest Management Guidelines / UC Statewide IPM Program (UC IPM) (ucanr.edu)

    Examples of ACP-effective materials which also suppress Katydids (from the UCIPM Guidelines):

    • Danitol
    • Baythroid
    • Mustang
    • Micromite
    • Entrust

    Examples of ACP-effective materials that can be used during the bloom period – some with restrictions (ALWAYS check the pesticide label and state bloom regulations prior to use):

    • Sivanto
    • Sefina
    • Micromite
    • Beleaf
    • Fujimite
    • ** = Restricted use to only 1 hour after sunset until 5 hours before sunrise.
    • **Delegate
    • **Entrust
    • **Exirel
    1. Suggested Dilution – 100 to 300 g.p.a. for airblast sprayers. FYI – many nutritional products are compatible with ACP insecticides however you should always check with your PCA before tank mixing.
    1. Please treat the borders of the block first, if possible, since ACP tend to populate block borders first. This way ACP will be driven toward the center of the block where they will get treated instead of away from the block and miss treatment.

    By adding an ACP-effective material to your spring foliar treatment, we will greatly lower both the ACP population and the risk of HLB being transmitted into our trees. Please let me know if you have any questions or concerns regarding this important effort by the SJV ACP/HLB Area-Wide Task Force.

    Sincerely,
    The ACP/HLB San Joaquin Valley Task Force

  • Growers Refine Date Palm Irrigation with UCANR Research

    California’s $86 million date industry produces more than half of the nation’s dates. Most of the fruit is grown in the arid Coachella Valley. Despite efforts by growers to conserve water, data was lacking on date palms’ actual water use to refine the best irrigation management for the crop until a recent research project led by Ali Montazar, UC Cooperative Extension irrigation and water management advisor for Imperial and Riverside counties.

    New research provides data California date growers need to apply a more precise amount of irrigation water to meet the trees’ needs to produce a healthy crop (photo by Ali Montazar).

    “California dates are grown in the hottest and most arid climate in North America and require substantial amounts of water in order to bring a successful crop to fruition,” Albert Keck, Coachella Valley date grower and chairman of the California Date Commission, wrote in a letter of support for this project. “In addition, there is scant modern research specifically and technically focused on growing dates in North America.”

    Montazar said there is a lack of irrigation management information on date palms worldwide.

    “The information developed in this study is expected to have a worldwide impact,” he said.

    To determine the evapotranspiration rate and crop coefficients for California date palms, Montazar teamed up with scientists at UC Davis, California Department of Water Resources, USDA Agricultural Research Service, and USDA Salinity Laboratory.

    The experiment was carried out in six date orchards in the Coachella and Imperial valleys. The sites represent various soil types and conditions, irrigation management practices, canopy characteristics, and the most common date cultivars in the region.

    “The findings of the project indicate that there is considerable variability in date palm consumptive water use, both spatially and temporally,” Montazar said. In other words, the amount of water the trees use varies considerably depending on each site’s growing conditions.

    He estimated the water needs for date palms planted in different soil types in the low desert region.

    “Growers will be able to use the science-based information and tools developed by this project to determine their date palm water needs and optimize the efficiency of water and fertilizer use in their groves,” Montazar said.

    Fruit bags protect date from insect damage and dust and prevent the fruit from falling to the ground (photo by Ali Montazar).

    The peer-reviewed article “Determination of Actual Evapotranspiration and Crop Coefficients of California Date Palms Using the Residual of Energy Balance Approach” is published in the journal MDPI Waterat https://www.mdpi.com/2073-4441/12/8/2253.

    “With a large quantity of new date plantings in the region, coupled with increasingly limited water resources in the Colorado River Basin Watershed, the knowledge anticipated to be developed by this research project has the potential to yield large dividends through not only improved water use efficiency, but also best management practices and crop quality,” said Keck of the California Date Commission.

    Although the research focused on Coachella Valley dates, Montazar said the results are likely to be useful to growers who have orchards with similar varieties, irrigation practices, and canopy and soil features in other locations.

    Montazar’s co-authors are Robert Krueger of the USDA-ARS National Clonal Germplasm Repository for Citrus and Dates; Dennis Corwin of USDA-ARS U.S. Salinity Laboratory; Alireza Pourreza UC Cooperative Extension specialist based at UC Davis Department of Biological and Agricultural Engineering; Cayle Little of California Department of Water Resources; Sonia Rios, UC Cooperative Extension advisor in Riverside County; and Richard L. Snyder UC Cooperative Extension specialist emeritus in the UC Davis Department of Land, Air and Water Resources.

    The date palm irrigation project was funded by the CDFA Specialty Crop Block Grant Program. — By Pamela Kan-Rice, UCANR

  • CA Citrus Mutual Joins Group to Speed CA’s Shift to Safer Pest Management

    Yesterday, the California Department of Pesticide Regulation and California Department of Food and Agriculture launched a broad new work group to accelerate the systemwide adoption of safer, sustainable pest control practices.

    The 25-member Sustainable Pest Management Work Group includes farmers, community members, university researchers and representatives from commodity groups and the pesticide industry. They are charged with identifying pathways to minimize the use of toxic pesticides and expand the use of integrated pest management practices; better protect public and environmental health; and engage, educate and promote collaboration to achieve these goals.

     “Transitioning away from toxic pesticides requires us to speed up the development of effective alternatives,” said CalEPA Secretary Jared Blumenfeld. “By giving our farmers a suite of integrated pest management tools, we can better protect farmworkers and some of California’s most vulnerable communities. This dynamic task force will give us the roadmap to achieve this bold vision.”

    “California agriculture is recognized not only for its quality and quantity, but also for the sustainable, innovative, forward-thinking way it is grown,” said CDFA Secretary Karen Ross. “Our farmers have been leaders in adopting integrated pest management and partnering with universities and technical assistance providers to meet our high standards for food, environmental and worker safety. This work group represents a broad array of perspectives to inform the next decade of research and development investment and new partnerships to continue the production of nutritious, delicious food and high quality agricultural products with the least impact to our surrounding communities.” 

    Funded in last year’s budget, the group’s work will build upon the recommendations of the Alternatives to Chlorpyrifos Work Group whose 2020 report identified alternatives to the hazardous insecticide and outlined actions to further support agriculture and the health of local communities, farmworkers and the environment. A new status update details additional actions DPR has taken based on the 2020 report, and how DPR and CDFA are working together to provide additional funding to the University of California and California State University to expand integrated pest management research and education. California prohibited virtually all uses of chlorpyrifos as of Dec. 31, 2020.

    The Sustainable Pest Management Work Group is part of the State’s larger commitment to accelerating the transition away from hazardous pesticides. To support the move, Governor Newsom is proposing to fund additional support for the transition by replacing the current flat-fee mill assessment on pesticide sales with a new risk-based tiered mill assessment, where higher toxicity pesticides are assessed a higher fee.

    The members of the Sustainable Pest Management Work Group include:

     

    1. Jenny Broome, Driscoll’s
    2. Don Cameron, Terranova Ranch
    3. Casey Creamer, California Citrus Mutual

  • California Avocado Commission Referendum Announced

    Every five years the California Department of Food and Agriculture holds a state-mandated referendum vote to provide California avocado growers the opportunity to determine whether the California Avocado Commission will be reapproved to continue for the next five years.

    “The referendum process is a vital component of the law that established the California Avocado Commission,” said Rob Grether, chairman of the CAC board of directors. “It provides growers the opportunity to cast their vote on continuing the operations of the organization.”

    Ballots will be mailed to eligible California avocado commercial producers on February 15, 2021 and must be postmarked and sent to CDFA for tallying by March 16, 2021. Eligible commercial producers who do not receive a ballot should contact the CDFA Marketing Branch staff at 916-900-5018. Results are expected to be tallied by CDFA and announced no later than March 31, 2021.

    “The California Avocado Commission exists to support California avocado growers and is governed by a board of directors comprised of their peers to ensure good stewardship of grower funds,” said CAC President Tom Bellamore.

    The Commission focuses on fostering grower viability by building demand for California avocados at a price premium and increasing the fruit’s perceived value, preference and loyalty. About 70% of CAC’s current budget goes toward marketing, which includes developing strategic, targeted programs with retailers and foodservice operators. Other key activities include advocating for California avocado growers on issues such as water, trade and export, supporting production research and grower education.

    There have been eight reaffirming referenda since the establishment of the California Avocado Commission in 1978.

  • FDA, CDFA, Western Center for Food Safety, and CA Ag Stakeholders Partner to Enhance Food Safety

    “California leads the world in leafy greens production and innovation. Industry and food safety officials are proud to partner on this in-depth scientific study protecting public health.” — CDFA Secretary Karen Ross

    The U.S. Food and Drug Administration is announcing the launch of a multi-year study to improve food safety through enhanced understanding of the ecology of human pathogens in the environment that may cause foodborne illness outbreaks. This initiative is being launched with partners including the California Department of Food and Agriculture (CDFA), the University of California, Davis, Western Center for Food Safety (WCFS), and agricultural stakeholders in the Central Coast of California.

    The launch of this study follows a series of E. coli O157:H7 outbreaks in recent years linked to California’s lettuce production regions, particularly the most recent three outbreaks in the fall of 2019 which collectively resulted in 188 people falling ill. In response, FDA launched an investigation, the findings of which are outlined in a report released in May 2020. The FDA also published a Leafy Green STEC Action Plan to address issues associated with leafy green Shiga toxin-producing E.coli (STEC) contamination. This new longitudinal study is included in the action plan, as well as the continuation of a similar study being conducting in the Yuma, Arizona, growing region.

    A key component of the Leafy Green STEC Action Plan is the need to address knowledge gaps in order to advance prevention. The multi-year study will examine how pathogens survive and move through the environment and possibly contaminate produce through work with water quality, food safety, and agricultural experts from the Western Center for Food Safety, representatives from various agriculture industries, and members of the leafy greens industry.

    Research teams will be collecting and examining samples from the environment including adjacent land, well and surface waters, soil inputs that include compost, dust and animal fecal samples.

    The California Central Coast region grows a significant portion of the nation’s leafy greens. The findings from this study will contribute new knowledge on how various environmental factors may influence bacterial persistence and distribution in this region, and how those factors may impact the risk of leafy greens becoming contaminated. Results from this collaboration will lead to improved practices to prevent or mitigate food safety risks, and ultimately enhance the safety of leafy greens grown in California.

  • CDFA Prune Handlers Annual Report

    California Department of Food & Agriculture — Prunes produced by handlers in 2019 totaled 9,791 tons, down from the 10,728 tons reported in 2018. This figure does NOT include prunes purchased from other handlers or producers.

    The total 2019 prune crop purchased from producers, for whom pricing had been finalized, reached 38,336 tons at an average price of $1,456 per ton, down significantly from the $1,715/ton average of 2018. This price is rounded to the nearest dollar per ton and includes all bonuses and allowances.

    Purchases from producers, for whom pricing was NOT finalized, totaled 39,828 tons. The average “good faith” estimate of the final weighted average price for this tonnage was $2,133 per ton.

    The quantity of all prunes purchased from producers was 78,164 tons for the 2019 crop. This figure does not include prunes produced by the handler or purchased from other handlers. The weighted average size count of tons purchased from producers was 57 for the French varieties and 58 for the Non-French varieties.

    The tonnage produced by the handler plus tonnage purchased from producers for the 2019 prune crop was 86,879 tons of French prunes and 1,077 tons of Non-French prunes for a total of 87,956 tons.

    Information contained in this report was supplied by prune handlers to fulfill reporting requirements of Sections 55601.7 and 55601.8 of the Food and Agricultural Code. The report includes all tonnages of prunes that were either produced by the handler or purchased from producers. The final weighted average price, including bonuses and allowances, has been reported for all contracts which were finalized.

    All 2019 crop transactions completed through the close of business on August 31, 2020 are included in this report. A “good faith” estimate of final weighted average price was reported for those contracts which were not final on the same date. The data are shown by major varieties at the State level only.

    DEFINITIONS

    Producer: A person or operator who is responsible for the prunes in the unprocessed state. A dehydrator operator is considered the producer of prunes if they grew or purchased fresh prunes and dehydrated them.

    Handler: Firm that processes and markets prunes.

    Finalized Purchases: Tonnage purchased from producers, for which a pricing contract has been completed.

    Non-Finalized Purchases: Contracted tonnage, for which a final price has not yet been determined.

    Free Tonnage: Tonnage received by a handler, for which the only Federal marketing order regulation is a minimum quality or size standard. Reserve tonnage is the tonnage set aside as authorized by a Federal marketing order.

    Weighted Average Price: Weighted average price reflects prices or “good faith” estimates of prices as reported by handlers and include any bonuses or allowances. 

  • HLB Detection Triggers Quarantine Expansion in San Bernardino & Los Angeles Counties

    A quarantine expansion has been declared following the detection of the citrus disease Huanglongbing (HLB), or citrus greening, in five residential citrus trees located in Rancho Cucamonga. This is the first time the disease has been confirmed in Ranch Cucamonga, marking the fifth city in San Bernardino County to have had a positive detection of HLB. The California Department of Food and Agriculture (CDFA) is working with the United States Department of Agriculture (USDA) and San Bernardino County to remove the HLB-infected tree and prevent the spread of HLB into neighboring areas.

    The expanded quarantine area will merge with the existing quarantines in San Bernardino and Los Angeles Counties. The expanded portion is bordered on the north by Big Tree Cucamonga; on the west by Pauda Avenue in Claremont and Mount Baldy Road; on the east by Interstate 15; and on the south by Foothill Boulevard and Interstate 10 in San Bernardino County.

    The updated HLB quarantine maps for San Bernardino and Los Angeles counties are available online. Please check this link for future quarantine expansions in these counties, should they occur.

    The quarantine prohibits the movement of all plant parts or citrus nursery stock out of the quarantine area. Provisions exist to allow the movement of commercially cleaned and packed citrus fruit. If you are a grower within the new quarantine expansion area, please contact CDFA’s emergency quarantine response program at 916-654-0312 for information on these provisions.

    Fruit that is not commercially cleaned and packed, including residential citrus, such as oranges, lemons, grapefruits and kumquats, must not be moved from the property on which it is grown, although it may be processed (removal of stems and leaves, and a thorough washing) and/or consumed on the premises.

    Residents are urged to take several steps to help protect citrus trees:

    • Do not move citrus plants, leaves, or foliage into or out of the quarantine area or across state or international borders. Keep it local.
    • Cooperate with agricultural officials placing traps, inspecting trees, and treating for the pest.
    • If you no longer wish to care for your citrus tree, consider removing it so it does not become a host to the pest and disease.

    CDFA staff have scheduled removal of the infected tree and are in the midst of a treatment program for citrus trees within 250-meters of the find site. By taking this action, a critical reservoir of the disease and its vectors will be removed, which is essential to protect other citrus trees on the property, neighbors’ trees and the community’s citrus from this deadly disease. CDFA, in partnership with USDA, local county agricultural commissioners and the citrus industry, continue to pursue a strategy of controlling the spread of the Asian citrus psyllids while researchers work to find a cure for HLB.

    Questions? If you are a citrus grower in San Bernardino County and have questions about this detection, please contact your grower liaison Sandra Zwaal at szwaal2@gmail.com.
