  • Novel Strawberry IPM Tool Included in CA DPR Grant Funding

    The California Department of Pesticide Regulation (DPR) announced $1.78 million in Alliance Grants for five projects that aim to increase the speed and the scale at which safer, more sustainable pest management practices are adopted across the state. Each project will promote innovative Integrated Pest Management (IPM) systems and practices in agricultural, urban or wildland settings.

    “Alliance Grants directly support the department’s mission to foster methods and tools to reduce reliance on pesticides and their impact on human health and the environment,” said DPR Director Julie Henderson. “We are excited by the potential of these five projects and will continue to invest in projects that promote the development and use of safer, more sustainable pest management.”

    DPR’s Alliance Grants Program funds projects that promote IPM, an approach that uses the least-toxic, effective method to solve pest problems. Since 2007, DPR has awarded more than $7.8 million in Alliance Grants. The enhanced funds for the 2022 DPR Grants Programs cycle were allocated by the 2021-22 state budget and represent a more than five-fold increase in available funding opportunities compared to historical funding levels.

    Alliance Grants are awarded to groups of experts and partners, also referred to as Alliance Teams, who work collaboratively to accomplish the goals of a given project.

    Alliance projects funded for agricultural pest management:

    • Promoting IPM practices that incorporate natural-enemy habitat to control pest insects. This project’s Alliance Team will engage in outreach with producers and agricultural professionals through videos that feature producers and researchers, field days and webinars, which will include an online continuing education course for pesticide applicators. This project will be led by Jo Ann Baumgartner at Wild Farm Alliance, a local non-profit conservation group in Watsonville.
    • Promoting the adoption of UV-C light, a non-chemical control, by strawberry growers on California strawberry farms. This project’s Alliance Team will showcase UV-C light as an effective, non-chemical alternative to chemical pesticides for controlling mites, mildew and mold. This project will be led by Dr. John Lin at California Polytechnic State University, San Luis Obispo.

    Alliance projects funded for urban pest management:

    • Addressing management of Argentine ants, the most common nuisance ant for which pesticide treatments are applied in urban environments. The Alliance Team for this project is focused on the implementation and promotion of a low-impact IPM approach for pest management professionals that uses pheromone attractants during initial treatment visits and targeted chemical baiting for maintenance visits, to reduce reliance on repeated use of insecticide sprays. This project will be led by Dr. Dong-Hwan Choe at University of California, Riverside.
    • Home visits to provide IPM education and intervention to disadvantaged communities in South Los Angeles. To improve the health and well-being of South Los Angeles residents, this project’s Alliance Team will make home visits to each family that enrolls in the program. The team will assess housing conditions; provide IPM interventions, including caulking cracks and sealing large holes; and offer other IPM education on reducing pest infestations. This project will be led by Nancy Ibrahim at Esperanza Community Housing.

    Alliance projects funded for wildlands pest management:

    • Combining manual removal of invasive primrose with native plant restoration through a private property owner incentive program, and an AmeriCorps partnership that will provide education and outreach to the community. The Alliance Team for this project is focused on management of creeping water primrose, an invasive aquatic plant, that is usually controlled with chemical pesticides. This project’s combination of IPM methods will improve water quality, protect fish habitat and enhance flood protection and prevention, as well as create strong and sustainable natural vegetative wetland communities around the shores of Clear Lake, California. This project will be led by Angela De Palma-Dow at the Lake County Watershed Protection District.For details about past recipients of DPR’s Grants Programs, please visit our department’s Pest Management Grants webpage.ABOUT THE DEPARTMENT OF PESTICIDE REGULATION

  • Impacts of Water Restrictions on Agriculture Production Cannot Be Understated

    United Vegetable Growers Cooperative — Our most precious resource is in critical condition. Chances are if you have driven through the Central San Joaquin Valley over the past 20 years you have seen prominent signs and billboards scattered along the interstate highways as well as the backroads.

    Many can attest to driving by one of these signs countless times while checking their fall lettuce in Huron. The simple five-word message has been crystal clear and prophetic for many years: “Food Grows Where Water Flows.” The message seems so basic and elementary that the critical message became tone deaf.

    West Coast farmers for generations have navigated multi-year cyclical drought conditions and have always managed to survive these conditions. Several seasons of heavy Sierra Nevada and Colorado Rockies snowpacks, along with above-average rainfall, and a short-term emergency was averted.

    The current West Coast water conditions are not an overnight development, it has been gradually building for years. As a result of the ongoing drought, the western region of the country’s most strategic water storage reservoirs have been reduced to historic levels.

    To provide context, the following are current levels of a few of California’s critical reservoir as of June 26: Lake Shasta is currently at 39% of its capacity and 50% of its historical average. Trinity is currently at 29% of its capacity and 38% of its historical average. Oroville is currently at 50% capacity and 65% of historical average. San Luis is currently at 40% capacity and 71% of its historical average.

    As a result, multiple CSJ irrigation districts have been subject to extensive water allocations, which have gotten more severe over the past two years. These allocations cover all agriculture farming, be it row crops or orchards. And as the season moves toward its midway point, unless there is record precipitation along with snowpack, conditions will remain dire. Water allocations will only be deeper next season and farm acres will continue to be furrowed.

    The challenge of this drought is not exclusive to California farmers. The Colorado River Basin is at its lowest levels ever recorded. With Lake Powell currently at 27% of capacity and Lake Mead at 29% of capacity. Now in an effort to preserve the water levels of these two critical reservoirs, drastic conservation measures are now being implemented. Targeted conservation levels of between two- and four-million-acre-feet of water (one acre-foot of water = 325,000 gallons) have been implemented to protect Lake Mead and Lake Powell reservoirs for the next four years.

    The primary effects of this conservation will be on the backs of the desert southwest agriculture, which ranges from the greater Yuma growing district to the Imperial Valley. The current outline of agriculture water conservation comes via usage restrictions, such as forcing farmers to determine which crops will be the most financially viable to farm. This is in addition to impacting the volume of crops that can be farmed, all while limiting the use of irrigation water. Keep in mind that during the winter months of November through March, over 85% of all leafy greens and vegetables consumed in North America is grown in the Greater Yuma and Imperial Valley growing districts.

    This is more than just a growing concern. The impact of agriculture production limitations based upon water restrictions cannot be understated. And long-term water storage solutions can no longer be ignored.

    Because, as the signs proclaim, only “Food Grows Where Water Flows.”

  • Progress on Prop 1 Funded California Water Projects

    California is in the midst of a serious drought, which is taking a major toll on our local agricultural industries. The Water Quality, Supply & Infrastructure Improvement Act (Prop 1) passed back in 2014, yet no construction of any of the funded projects has commenced.  Watch this brief interview with Emily Rooney from the Ag Council of California as she shares a progress report on these projects and how they will help address California’s water crisis.
    Please thank this video’s sponsor Suterra for their industry support.
  • California Ag Coalition Requests Immediate State Action on Water Needs

    Due to an economically crippling drought and the overwhelming regulatory demands of California, several agricultural groups formed a coalition and recently sent a letter to the governor and state legislature, both informing them of the challenges impacting farming families and requesting immediate action and funding to boost water storage and supplies. Watch this brief interview with Emily Rooney from the Ag Council of California as she explains.

  • Best Farming Practices for Treated Seeds Underscores Commitment to Environmental Stewardship

    As planting season begins across the West, Western Plant Health is reminding farmers about the importance of following basic steps that will help ensure the ongoing stewardship of pesticide-treated seeds, which help reduce the overall use of pesticides.

    This major agricultural advance provides seed treatments that help protect developing seeds during their most vulnerable time – at planting and germination. Their highly targeted, precise application means less impact on the surrounding environment.

    Studies have shown that without this innovation, up to 5X’s more pesticides would have to be applied by traditional means to the crop. Fewer applications also require fewer tractor passes, which in turn reduces greenhouse gas emissions and offers yet another way for farmers to mitigate climate change.

    Treated seeds represent one of many valuable and innovative approaches enabling farmers in the West to be more productive, while using resources more efficiently and protecting the environment. That is why adopting these best practices is critical:

    1) Follow label directions on seed containers;

    2) Eliminate flowering plants and weeds in the field prior to planting;

    3) Minimize dust by using advanced seed flow lubricants and mechanisms;

    4) “Bee Aware” of honey bees and hives located near the field;

    5) Ensure that any spilled seeds are removed to protect wildlife and the environment; and

    6) Remove all treated seed left in containers and equipment after each planting, and dispose of any remaining seeds after planting is completed.

    These are simple, effective and important stewardship practices when it comes to treated seeds. Let’s help protect this critical technology for farmers by observing these practices. Remember, always follow label directions on seed containers for proper handling, storage, planting and disposal to minimize risk to applicators, wildlife and the environment!

    Farmers are the original environmentalists; properly using treated seeds is a way to continue that tradition and value to protect the land for future generations. – By Renee Pinel, President & CEO of Western Plant Health Association

  • Vertical, Indoor Farming Boosts Yield and Anti-Cancer Nutrition of Watercress

    How does it sound to grow plants without sunlight or soil, in racks going up and down instead of in rows on the ground? That’s how crops grow in indoor vertical farms, where nutrient-rich, recycled water feeds plants under red and blue LED lights. This innovative approach gives farmers the chance to alter crops as they like, whether that means making lettuce red or producing extra-flavorful herbs. The added benefits: Amid continuing drought across the western United States and water scarcity in many other parts of the world, this system uses up to 95% less water than traditional farming. And, it has no need for pesticides.

    Watercress is an ideal crop for vertical farming. Traditionally, this semi-aquatic, leafy green from the nasturtium family grows in high-quality chalk streams in Europe. It’s also packed with nutrients, with a distinctive peppery taste that makes it a yummy addition to salads. The flavor hints at anti-cancer benefits conferred by the same natural chemical compound that creates watercress’s flavor

    Now, scientists from the UC Davis Department of Plant Sciences have discovered that watercress grown in indoor, vertical farms has the highest phytonutrient content and yield, compared to cress grown in soil in California and in traditional, outdoor farms in the United Kingdom, according to a study just published in Scientia Horticulturae. Levels of the plant’s anti-cancer compound also were further elevated by increased blue light when grown indoors. This discovery shows how the quality of food can be improved for people’s health when crops are grown indoors.

    This work has been made possible with a new, specialized growing facility on campus for research in controlled environment agriculture. Multiple faculty members in the College of Agricultural and Environmental Sciences are working in this area. The indoor farm also is being used to train the next generation of high-tech farmers, with students visiting the facility and growing red romaine lettuce this year. — By Yufei Qian & Lauren Hibbert, UC Davis

  • Imports and Production from Mexican Tomato Industry Remain Strong

    Assuming normal conditions for open-field cultivation and continued growth in the sector’s use of greenhouse and shade technologies, Mexico’s fresh tomato production for October-September marketing year (MY) 2022/23 is projected to match the official production estimate for MY 2021/22 of 3.7 million metric tons (MMT). Despite abnormally dry conditions in some areas, no major production shortfalls due to weather are present at this time. The largest producing state remains Sinaloa with 23 percent of total production, followed by San Luis Potosi, Michoacan, Baja California Sur, Zacatecas, Morelos, Puebla, and Jalisco. To obtain higher yields, Mexican growers continue to transition from open field towards more controlled production under protected cultivation methods. Exports to the United States will also remain strong due to available exportable supply and flat domestic consumption.

    Production

    In MY 2022/23, Mexico’s tomato sector is expected to maintain its current productivity, assuming normal growing conditions and continued strong demand from the U.S. market, with Post projecting production will remain at 3.7 MMT. Tomatoes are grown across Mexico throughout the year with two important production/harvest peaks that overlap: from December to April with fruit from the state of Sinaloa, Mexico`s largest tomato producer, dominating the domestic market and exports to the United States; and from May to November the major suppliers in order of supply are San Luis Potosi followed by Michoacan, Baja California Sur, Zacatecas, Morelos, Puebla, and Jalisco. At the time of this report, production for MY 2021/22 is estimated to be 3.72 MMT based upon higher yields as the sector continues to expand in the greenhouse and other technological methods of production. This is occurring in both current major producing areas as well as lower volume states. The official production figure for MY 2020/21 is 3.03 MMT, according to Mexico’s Agrifood and Fisheries Information Service (SIAP). In MY 2020/21, Sinaloa produced over 709,000 MT followed by San Luis Potosi with 343,670 MT, Michoacan with 237,841 MT, Baja California Sur with 164,507 MT, and Zacatecas with 158,970 MT. For production share of major producing states in 2021 see Figure 1 below.

    According to available data from SIAP, Sinaloa remains the leading supplier of tomatoes followed by San Luis Potosi and Michoacan. These top three producing states account for over forty percent of national production, but tomatoes are grown throughout the country. For production history of the top five producing states see Figure 2 below. While Sinaloa remains the largest producer in Mexico at the state level, the majority of growth in Mexico’s national production is dispersed across San Luis Potosi, Michoacan and other smaller producing states.

    The use of different levels of technology for protected agriculture production allows Mexican growers to supply the U.S. market year-round. Greenhouse, shade houses, and high tunnel systems are in use throughout the country. According to available data, in 2010, Mexico’s production from these systems was less than 1.0 MMT. By 2012, tomatoes cultivated from these protected methods reached 1.61 MMT. This ongoing trend is due to a combination of open-field production converting to various shade and tunnel methods, as well as most new production being in the form of greenhouse, shade, and tunnel cultivation. From 2012 to the present day, non-open-field production has become an increasingly important share of national production, and accounts for most of the sector’s growth. By 2020/21, tomato production from protected sources reached an estimated 2.21 MMT, accounting for 67 percent of total tomato production. Figure 3 below shows this progression in which open-field production has become a smaller share of Mexico’s production.

    While Mexico’s domestic consumption of fresh tomatoes is not covered in depth by this report, understanding basic national attributes helps to inform trends in production and trade. Mexico exports over half of its annual production. Based upon available population and per capita consumption data, Mexico’s annual tomato consumption stands at approximately 1.75 MMT. In 2021, the Secretariat of Agriculture and Rural Development (SADER) estimated annual per capita consumption of tomatoes in Mexico at 13.4 kg/person.

    Trade

    In MY 2022/23, Post forecasts Mexico’s fresh tomato exports at 1.9 MMT due to expected rising supply, limited growth in domestic consumption, and robust U.S. demand. Mexico continues to be the largest supplier of fresh tomatoes to the United States, and is the world’s largest exporter of fresh tomatoes as a result. Based upon available data and pace of trade, post estimates exports for 2021/22 to reach 1.7MMT, a marginal decrease from the year prior. Although exports to the United States are year- round and consistently above 100,000 MT per month, the largest volume of exports generally takes place from January to March (see Figure 4). In 2020/21, Mexico exported over 1.76 MMT of tomatoes to the United States, holding an estimated 91 percent market share, with Canada and several other Latin American suppliers exporting a much smaller quantity. Likewise, the United States absorbs nearly all of Mexico’s exportable supply of fresh tomatoes. Mexican imports of fresh tomatoes are negligible, totaling just 640 MT in MY 2020/21.

    Mexican tomatoes follow well-established supply chains to markets throughout the United States. The greatest volume of Mexican tomatoes enter through the Laredo customs district, followed by the Nogales and San Diego customs districts. The reader should note that the Laredo district has four important ports of entry (POE) for the crossing of tomato shipments. In order of volume, these are: Pharr, Laredo, Brownsville, and Progreso. In comparison, the Nogales customs district consists of one crossing POE for tomatoes, as does the San Diego district. For the share of tomato exports by Customs District see Figure 5 below. Once processed and cleared by U.S. authorities, specialized wholesalers redistribute product to retail chain distribution centers further north in the United States. Product

    crossing through the Laredo POE typically reach distribution centers further north in Texas to be consolidated with other goods and distributed to points of sale.

    Policy

    The Tomato Suspension Agreement (TSA) of fresh tomatoes grown in Mexico ensures that signatory producers and exporters sell all fresh and chilled tomatoes to the United States at or above the TSA reference price. Tomatoes for processing are exempt from the reference price. Tomato shipments are inspected upon entry for compliance with existing U.S. import regulations by agencies including Customs and Border Protection (CBP), United States Department of Agriculture (USDA), and the Food and Drug Administration (FDA). The reader should be cognizant that the TSA is different from import requirements of fresh tomatoes under Section 8e of the USDA Agricultural Marketing Agreement Act of 1937 (AMAA). Also, tomatoes are inspected at U.S. ports of entry by CBP and USDA to ensure product is free of evidence of Tomato brown rugose fruit virus (ToBRFV), and are also subject to FDA inspection. — By Eduardo Lozano, USDA Foreign Agricultural Service

  • New Herbicide Research Offers Sweet (Potato) Relief

    Sweet potatoes are a favorite Thanksgiving dish. Researchers at Clemson University have found that using “safeners” in addition to herbicides can help increase yields (Credit: Canva).

    Despite being beloved by most, sweet potatoes are often misunderstood. They’re unrelated to potatoes, for starters. And they’re even different from yams.

    Yet we can’t get enough. U.S. farmers have been increasing their production of sweet potatoes for years. And now the annual crop is worth more than $600 million.

    To grow the best crop, farmers have to help their sweet friends fight back against the usual suspects: weeds. Weeds will steal water, nutrients and even sunlight. Left unchecked, weeds will completely ruin a field of sweet potatoes.

    Herbicides can help, but they’re not a cure-all. Controlling broadleaf weeds is especially tough. That’s because sweet potatoes are also broadleaf plants, which means they will also be damaged by herbicides designed to attack broadleaf weeds.

    Enter “safeners.” These chemicals can make herbicides safer, hence their name. Recently, Giovanni Caputo and his team from Clemson University and the U.S. Department of Agriculture tested several safeners to see if they could help sweet potatoes. They discovered a few new formulas that might give a boost to farmers.

    The researchers recently published their findings in Agrosystems, Geosciences and Environment Journal, a publication of the American Society of Agronomy and the Crop Science Society of America.

    They set up their experiments in a greenhouse in South Carolina, a major sweet potato producing state. The scientists tested the herbicides bentazon and mesotrione on two varieties of sweet potatoes, “Beauregard” and “Covington.” The safeners they used included two types of plant hormones, which help the plant respond to stress. They also tested melatonin which is well-known for its role in the sleep cycle in humans, but it also occurs naturally in plants and is involved in growth and photosynthesis.

    The researchers found that different safeners worked better depending on the variety of sweet potato and the herbicide being used. For example, melatonin greatly reduced how much bentazon injured “Beauregard” plants. But the Covington variety didn’t benefit as much. Instead, “Covington” plants were best protected by ascorbic acid, better known as vitamin C.

    Similarly, melatonin and ascorbic acid provided the best benefit with the mesotrione herbicide. But the other plant hormone they tried didn’t help as much for either variety.

    To make sure the safeners didn’t affect the herbicide’s ability to kill weeds, The Clemson team tested the new formulas on Palmer amaranth and yellow nutsedge, both big weedy pests. Fortunately, the new formulas were still effective weed killers. It’s not entirely clear why the safeners helped the sweet potato plants but not the weed. But more tests might reveal what causes the different reaction.

    The upshot is that these new formulas seem promising for providing farmers with new tools to protect their crops from damaging weeds. They’ll need to perform more trials, especially in real farm fields, to perfect the formula. But a new herbicide system that could better protect sweet potatoes would be a boon to farmers and Thanksgiving tables alike. Now that’s a sweet deal.

    Funding for this research was provided by Agricultural Society of South Carolina.
