  • CA Valencia Orange Production Forecast At 17.2 Million Cartons

    The March 2021-22 Valencia orange forecast is 17.2 million cartons, down from last year’s utilized production of 19 million. This forecast was based on the results of the 2021-22 Valencia Orange Objective Measurement (O.M.) Survey, which was conducted from January 11 to February 28, 2022. Estimated fruit set per tree, fruit diameter, trees per acre, bearing acreage, and oranges per carton were used in the statistical models estimating production. The season had experienced scattered precipitation in some areas but mainly warm and dry conditions in January and February. Survey data indicated an average fruit set per tree of 541, a 0.7% decrease from the previous year and slightly above the five-year average. The average March 1 diameter was 2.459 inches, down 3.6% from the previous year and slightly below the five-year average of 2.539.

    SURVEY HISTORY

    A Valencia Orange Objective Measurement Survey was conducted from the 1985-86 to 1993-94 seasons before suspension due to a lack of funding. The survey has been conducted since it was reinstated for the 1999-00 season, with the exception of the 2006-07 season due to a substantial freeze. The data from the first three years after the survey was reinstated were used for research purposes in developing crop- estimating models.

    SURVEY SAMPLE

    A sample of 381 Valencia orange groves were randomly selected proportional to acreage, county, and variety representation in the state, with 349 of these groves being utilized in this survey. Once a grove was randomly chosen and grower permission was granted, two trees were randomly selected for each grove. For each randomly selected tree, its trunk was measured along with all connected branches. A random number table was then used to select a branch, and then all connected branches from the randomly-selected branch were measured.

    This process was repeated until a branch was reached with no significant limbs beyond it. This randomly-selected branch, called the terminal branch, was then closely inspected to count all fruit connected to it, as well as all of the fruit along the path from the trunk to the terminal branch. Since each selected path has a probability of selection associated with it, a probability- based method was then applied to estimate a fruit count for the entire tree.

    In the last week of the survey period, fruit diameter measurements were collected on the right quadrant of four trees surrounding the two trees of every third sampled grove. These measurements were used to estimate an average fruit diameter per tree. The sampled groves were primarily in the top Valencia orange producing counties of Tulare, Kern, Fresno, Ventura, and San Diego.

  • California Prune Board Honors Women Across Industry

    In celebration of International Women’s Day on March 8, the California Prune Board reflected on the various women throughout the prune industry who drive continuous growth and improvement for the organization and the consumption of prunes. In critical roles including Growers, Chief Executive Officers, Researchers, and Directors, women across the prune business are shaping the decisions that define an industry.

    “Demand for California Prunes has steadily increased in the past two years and historically women have been the primary purchasers of prunes,” said Kiaran Locy, Director of Brand & Industry Communications. “The truth is prunes are enjoyed by everyone and the women in our industry are tenacious and their insights and expertise are keeping us relevant and moving us forward.”

    These 5 industry leaders within the California Prune industry, provide valuable direction and insight across a variety of professions:

    • LindaKay Abdulian is the President and CEO at National Raisin Company and has worked in the prune business for over 10 years.

    “Agriculture is a tough industry. The people involved are trenchant and as a woman in a dominant man’s world, you prepare for every encounter. The prune industry is no exception. The players are the best in the business, man, or women. You come prepared and you will succeed.”

    • Sandie Mitchell is a California Prune Grower who has been growing prunes for 44 years. She is also an Executive Committee Member for the California Prune Board

    “Women are very quality oriented. When it comes to our families, we only want the best. As a California Prune grower, we have dedicated our farming operation throughout the years to growing a premium product for the consumer.”

    • Sarah Bradley Castro is a Staff Research Associate at UC Davis and has led the prune breeding program since 2008.

     

    “I continue to be inspired by the growing number of women in agriculture and agricultural research. In my working with UC Davis, California Women in Agriculture, and the Prune Board it is clear the innovation and energy women bring to the industry will carry us forward to a successful future.”

    • Natalie Mariani Kling is the Marketing Manager for Mariani premium dried fruit and a Certified Clinical Nutritionist. As a 4th Generation Mariani, she has been working in the prune business since she could walk steadily through the orchards.

    “Working with real, whole food is an honor and a responsibility. Mother Nature is no joke, and we rely on the great women (and men) in our industry who sow their time, expertise, and commitment into growing food that families around the world can enjoy. As a nutritionist, prunes have a special place in my heart. They may be one of superfood’s best kept secrets. Watch out world!”

    • Esther Ritson-Elliott is the Director of International Marketing & Communications with the California Prune Board. She has worked with the organization for over 30 years.

    “Agriculture itself is often perceived as a ‘male’ career, yet figures published in 2017 reveal that more than one third of U.S. farmers are women, and over half of all farms have at least one female decision maker. That equates to 1.2 million female producers making a significant contribution to U.S. agricultural sales, including those working in the prune industry. I make it my mission to share the fruits of their labor, promoting the commitment, passion and contribution of our prune growers and championing their work – male and female alike.”

    Building awareness that drives consumption for California Prunes starts with a premium product and strategic approach. The California Prune industry invests in nutrition and crop research as well as building global markets for the promotion of prunes. California is the world’s largest producer of prunes and supplies over 90% of the prunes in the U.S. and 40% of the world’s production.

  • DPR Proposes Regulatory Restrictions on the Use of Neonicotinoids to Protect Bees

    In an effort to reduce risks to bees, the California Department of Pesticide Regulation filed an official notice of formal rulemaking as a first step in the regulatory process to limit how and when neonicotinoids can be used in agricultural settings.

    Neonicotinoids are a group of insecticides that are widely used as an alternative to chlorpyrifos, which DPR ended virtually all use of in 2020. At certain levels of exposure, neonicotinoids present risks to pollinators. DPR’s proposed regulations are based on extensive scientific studies and would create new requirements and restrictions for the use of neonicotinoid products containing any of four active ingredients: imidacloprid, thiamethoxam, clothianidin and dinotefuran. DPR estimates the regulations will impact 57 products currently registered in California and will reduce the amount of neonicotinoids applied across the state by approximately 45%.

    The regulations include tiered restrictions based on the chemical used, the type of crop and the time of year the neonicotinoid is applied in order to protect pollinator health. For example, applications to certain flowering plants that are attractive to bees would be prohibited when the plants are in bloom and when bees may be foraging. The regulations also set limits on applications of multiple neonicotinoids and what application methods may be used by growers. They also include an exemption for quarantine pests to provide the option, if necessary, to treat pests that can severely damage crops and food supply chains. The regulations address both risks to bees and ensures the protection of pollinators critical to growers and the agricultural sector.

    “DPR evaluates pesticides on an ongoing basis using the best available science and data to mitigate adverse impacts on ecosystems and the environment,” said DPR Director Julie Henderson. “Our neonicotinoid reevaluation led to the significant advance in pollinator protection reflected in our proposed regulation.”

    The department began re-evaluating imidacloprid and the related neonicotinoids, thiamethoxam, clothianidin and dinotefuran in 2009. DPR completed its scientific review in July 2018, publishing the California Neonicotinoid Risk Determination, and began development of control measures necessary to protect pollinator health. The department’s development of draft regulations included a pair of initial public webinars and a public comment period in 2020. The formal rulemaking process initiated by DPR today will include the opportunity for the public to submit written comments on the proposed regulations. For more information, see DPR’s Neonicotinoid Reevaluation webpage.

    “Our continuous evaluation of pesticides plays a critical role in accelerating a transition to safer, more sustainable pest management that protects the health of our communities, our pollinators and the environment as a whole,” said Henderson.

    As part of its regulatory mandate, DPR evaluates pesticide products for potential human health and environmental effects before they can be registered for legal sale and use in California. Prior to DPR review, pesticide products are evaluated and registered by the U.S. Environmental Protection Agency (U.S. EPA).  U.S. EPA’s and DPR’s registration review and required pesticide label instructions – including application instructions and personal protective equipment requirements – are designed to mitigate potential risks to human health and the environment.

    DPR’s registration process includes the review of extensive scientific studies on human health and environmental impacts, safety and efficacy. After pesticide products have gone through this process and are registered, DPR also carries out a continuous evaluation process for pesticides following registration to take into account evolving scientific understanding. This continuous evaluation process can include formal reevaluation of pesticides and mitigation measures, as in the case of the neonicotinoids that are the subject of the department’s proposed regulation, conducting exposure studies, conducting human health risk assessments, monitoring air and water for pesticides, and investigating information that indicates a pesticide may have caused an adverse effect on human health or the environment. Pesticides currently undergoing DPR’s re-evaluation process are listed on the department’s website and the results inform state-specific restrictions, mitigation measures or conditions for use.

    ABOUT THE DEPARTMENT OF PESTICIDE REGULATION

    The California Department of Pesticide Regulation’s mission is to protect human health and the environment by fostering safer and sustainable pest management practices and operating a robust regulatory system to monitor and regulate the sale and use of pesticides across the state.

    DPR’s work includes conducting scientific evaluation of pesticides to assess and mitigate potential harm to human health or the environment prior to and following registration, registering all pesticides prior to sale or use in California, monitoring for pesticides in the air and water, and enforcing pesticide laws and regulations in coordination with 55 County Agricultural Commissioners and their 400 field inspectors. DPR invests in innovative research to encourage the development and adoption of integrated pest management tools and practices and conducts outreach to ensure pesticide workers, farmworkers and local communities have access to pesticide safety information.

  • CA Prune Board Advances Study of Prunes and Bone Health

    The California Prune Board (CPB) is leading the way in investigating a connection between prunes and favorable bone through a growing body of evidence spanning two decades. Building on this remarkable and extensive research, the organization is announcing recently published scientific data supporting the role prunes may play in optimal bone health, while previewing a pipeline of clinical trials currently underway.

    “The science has shown us that something unique is going on with prunes, as we’ve uncovered some remarkable connections to bone health,” said Donn Zea, Executive Director, California Prune Board. “With every study we learn something more compelling further piquing our curiosity. Our research program has more to explore, and we’re excited to see where this takes us in terms of learning more about the benefits of prunes for bone health.”

    RECENTLY PUBLISHED HIGHLIGHTS

    In a recent review paper published in Advances in Nutrition titled, “The Role of Prunes in Modulating Inflammatory Pathways to Improve Bone Health in Postmenopausal Women,” researchers from Pennsylvania State University examined the relationship between prune consumption, oxidative stress, inflammation, and favorable bone health outcomes, summarizing the results of preclinical and clinical trials. They reported that the bone-protective effects of prunes found in postmenopausal women appear to be connected to the antioxidant and anti-inflammatory activity that prunes stimulate within the body. Moreover, the authors also suggested that prunes’ favorable effect on bone may be partially explained by changes in the gut microbiota that can come from regular prune consumption.

    Additionally, in a USDA-funded clinical trial recently published in Nutrients, titled “The Short-term Effects of Prunes in Improving Bone in Men,” investigators from Florida State University sought to test the effect of daily prune consumption on bone metabolism in 35 men over the age of 50 who had some bone loss. The early findings showed a reduction in osteocalcin, a biomarker of bone turnover, and an increase in what’s known as the OPG:RANKL ratio, indicating prunes may have a positive effect on bone status after just three months of eating this whole fruit daily. These preliminary findings are a subset of a larger study with results that have not yet been published but are anticipated in the next 12-18 months.

    “As a researcher it’s exciting to see a positive change in bone turnover in these men from prune consumption after a relatively short period of time. We anticipate even more favorable results in bone status once the men have completed a full year of eating prunes every day,” said Principal Investigator Bahram Arjmandi, PhD, RDN, Professor and Director, Center for Advancing Exercise and Nutrition Research on Aging, Florida State University.

    RESEARCH UNDERWAY

    In addition to this recently published data, the following nutrition studies from highly credentialed research institutions are currently in progress and working toward completion or journal publication:

    Randomized Controlled Trial of Dietary Supplementation with Prunes on Bone Density, Bone Geometry, and Bone Strength in Postmenopausal Women

    Principal Investigator: Mary Jane De Souza, PhD – Pennsylvania State University

    With a cohort of over 200 postmenopausal women, this is the largest clinical trial to date to investigate the effect of prunes on bone status as a non-pharmaceutical plant-based strategy to combat bone breakdown.

    The Effects of 12-months of Prune Consumption on Bone Mineral Density and Bone Turnover Markers in Korean Postmenopausal Women with Osteopenia

    Principal Investigator: Peter Clifton, PhD – University of South Australia

    Co- Principal Investigator: Yoona Kim, PhD, RD, Gyeongsang National University, Korea

    This clinical trial in South Korea is the first study outside of the United States to investigate the bone protective benefits of daily consumption of prunes in Korean osteopenic postmenopausal women.

    The Impact of Consuming California Prunes on Bone Health of Young Women Using Hormonal Contraceptives

    Principal Investigator: Shirin Hooshmand, PhD, RD – San Diego State University

    The study is investigating the impact of prune consumption on bone formation and in preventing or slowing bone loss in young women 18-25 years old taking hormonal contraceptives.

    “Bone health, whether optimizing bone formation early in life or preventing bone loss in adulthood, is critical at all life stages given that the human skeleton is dynamic, undergoing a continuous cycle of building and breaking down bone,” said Andrea N. Giancoli, MPH, RD, Nutrition Advisor, California Prune Board. “We are aiming to better understand the role of prunes in this cycle that is strongly correlated to gut health, inflammation, and oxidative states within the body.”

    While it remains unclear what bioactive compounds in prunes are responsible for the beneficial effects on bone, the prune-positive bone health story may be partially due to the array of vitamins and minerals in California Prunes known to influence bone status, namely boron, potassium, copper and vitamin K. Prunes are also rich in phenolic compounds, which research suggests may inhibit bone breakdown and stimulate bone formation. Key future directions to bridge the gap in the areas of bone and the gut-bone axis are on the research horizon.

    CREATING A VISION FOR THE FUTURE 

    Advancing bone-focused nutrition research and expanding the connection to the gut-bone axis, while also exploring clinical trials in various life stages and international populations is at the heart of the California Prune Board’s strategic vision for continued research into the next decade.

    The integrity of the California Prune Board’s nutrition research program is demonstrated by the renowned research and academic institutions with whom it has partnered and the rigorous process that ensures credible research decisions.

    A top-caliber nutrition research advisory panel, led by Mary Jo Feeney, MS, RDN, FADA, FAND, helps to guide these California Prune nutrition research efforts. The panel is comprised of highly experienced researchers and nutrition experts from academic institutions, including Tufts University, Cleveland Clinic, Pennsylvania State University, University of Minnesota, and San Diego State University. This independent advisory panel provides vision and oversight of the nutrition research program and ensures scientific rigor for every project that explores the nutritional and health benefits of California Prunes.

  • Weather Conditions Cause of Rind Breakdown in Satsuma Mandarin

    Although you never know about the weather, we do know that if heavy rain occurs after color break in mandarins there can be significant rind breakdown. This problem can destroy much of the crop and the problem is largely preventable.

    Pre-harvest rind decay of mandarins in California generally occurs shortly after rain falls and is most severe on Satsuma mandarins. Although some researchers have associated the problem with fungi such as Alernaria species, isolations from affected fret have been inconsistent. Inoculations with isolated fungi only sometimes reproduce disease symptoms and only on water-soaked fruit. Furthermore, in preliminary field trials there were conducted in Butte Co in the fall of 2002 and 2003, fungicide treatments that included Topsin-M, Pristine and Abound only reduced the incidence of disease from 99% in the control to approximately 90% .  These data suggested that mandarin rind breakdown is a physiological, abiotic disorder of fruit rather than a pathological problem and the fungi isolated are rather secondary causes of rind decay than primary pathogens.

    Rind breakdown of citrus was previously reported by Fawcett and others in the 1930s. Wet weather combined with a sudden decrease in temperature was shown to result in generation of rind oil and collapse of cells just under the cuticle. In laboratory and field trials in 2003, fruit treatments with water repellants reduced the incidence of rind breakdown to very low levels. Field trials were again conducted in the fall of 2004. Fungicide treatments were ineffective in these trials. In all trials, application so Vapor-Gard or Omni oil significantly reduced the disorder. In all programs with Vapor-Gard and Omni oil, a first application was made at the end of October and there was no significant difference in efficacy when additions applications were done. When tree were protected from rainfall using a tent, the disorder could not be detected, indicating the rind breakdown is correlated to rainfall.

    In summary, results from the trials support previous findings by Fawcett that mandarin rind disorder is an abiotic, weather-related problem of mature fruit that has undergone a green to orange color change. Using a water repellant helps protect the fruit. — By Ben Faber, UCCE Ventura County Advisor

  • Research Indicates Paint Not Effective At Protecting Young Avocados From Herbicide Drift

    California Avocado Commission — While it is often common practice for fruit growers to apply white latex paint to the bottom 2 to 3 feet of young, newly planted trees in order to provide some protection from herbicide drift, researchers note there is little evidence to prove this practice is effective.

    A recent blog post by Dr. Ben Faber summarized the findings of a California field experiment conducted in 2017 that measured the impact of latex paint in preventing herbicide injury on young almond trees. The block of trees consisted of greenhouse-grown trees in cartons. Nine weeks prior to the herbicide applications, the cartons were removed for trees in the “no paint” and “old paint” sections so their bark could harden off. Two days prior to applying the herbicide, the cartons were removed for the “new paint” trees and then the trees were painted.

    According to the researchers:

    • The paint did not provide significant protection from glyphosate or glufosinate.
    • Tree stress caused by trunk-applied herbicides was lowest in trees with no paint, suggesting that allowing the bark to harden on young trees is an important means of protecting them from herbicide drift.
    • In most treatment combinations, old and new paint applications did not reduce tree stress as effectively as allowing the bark to harden on trees nine weeks prior to application.
    • The most effective means of protecting trunks was installing a carton. However, it is important to remember that once the carton is removed (as the tree matures), there may be green bark present which would be vulnerable to herbicides.
