  • Pollinator Partnership Announces Three New Designations for Bee Friendly Farming

    Pollinator Partnership (P2) is proud to announce enhancements and improvements to its Bee Friendly Farming (BFF) program to better recognize engage and support BFF participants and pollinators everywhere. The new BFF program will have three categories that allow them to engage with all participants at a finer scale while addressing their goals: Bee Friendly Farming Certified, Bee Friendly Farming Partner and Bee Friendly Farming Garden.

    Bee Friendly Farming Certified designation will apply to large-scale commercial farms, ranches, wineries and other land-use businesses that grow food and other resources. This certification will require compliance at registration and every third year to be validated in the seven specific criteria required to qualify. “From habitat to cover crops to best management practices, the Bee Friendly Farming Certified mark will identify farms engaged in science-based Bee Friendly Farming practices,” said BFF Coordinator Miles Dakin. “This enables us to enhance grower and pollinator benefits through greater engagement in nutrition, habitat, biodiversity and other guidelines.”

    Bee Friendly Farming Partner includes sponsorship from individuals and companies, as well as apiarists, who do not actively manage their own landscapes but wish to support the BFF program. Multiple tiers of sponsorships are available to provide the resources necessary to build and maintain the BFF program.

    The third category of recognition, Bee Friendly Farming Garden, includes smaller landscapes, community gardens and homeowners who voluntarily adhere to the seven criteria of Bee Friendly Farming actions. By separating and reorganizing these distinct members, BFF can better recognize the different contributions by farmers, apiarists, home gardeners, community members and commercial sponsors to support vital pollinators.

    “After conversations with long-standing participants, environmental groups, grower associations and sponsors, we saw a clear need to further refine the BFF experience and to add a level of scrutiny and permanence to the certification aspects of Bee Friendly Farming,” said Laurie Davies Adams, President of Pollinator Partnership, parent organization of Bee Friendly Farming. “This new tri-level approach will still recognize existing affiliates as BFF Partners, while taking a great step forward for the dedicated agricultural community that seeks rigorous and validated certification of its adherence to best practices for pollinators. In all instances, BFF will provide excellent guidelines for all levels of BFF practitioners.”

    The three categories have slightly different criteria and benefits. Some currently certified historic BFF participants may fall into a different category and will be contacted about the changes.

  • New Recommendations for Laurel Wilt Disease

    By Ben Faber, UC Cooperative Extension — Laurel Wilt Disease of Avocado and the relatives of avocado in the Laurel Family has devastated the the forests along the east coast from North Carolina down to Florida and along the Caribbean into Texas.  It has caused significant losses to wildlands and to the Florida avocado industry.

    Ambrosia Beetle

    The extent of the native tree loss is shocking and there is very little that can be done to correct the problem, other than to curb the spread of contaminated wood that is spread by humans,  There has been some success in the avocado orchards. While there is no “silver bullet”, there is some progress, e.g. pruning to increase light levels to suppress Ambrosia Beetle activity.  In addition, research has continued for:

    • Vaccinations to protect avocado trees from the LW pathogen
    • Developing a faster LW diagnostic tool
    • Screening scions and rootstocks for tolerance/resistance
    • AB control tactics and suppression
    • Molecular understanding of the pathogen
    • Economics and the LW epidemic

  • Bringing the Next Generation of Avocados to Market

    UC Riverside has entered into a $2.25 million partnership with Spain-based Eurosemillas S.A., a global leader in the commercialization of agriculture innovations, to help the university bring to market the most promising and advanced avocado scions and rootstocks in its collection.

    If successful, these varieties would meet diverse regional growing requirements, exhibit better post-harvest characteristics, increase yields, provide resistance against disease, and expand consumer market diversity.

    “Eurosemillas has successfully commercialized citrus varieties developed at UC Riverside in the past. They have the global network and expertise to do the same with the next generation of avocados,” said Brian Suh, director of technology commercialization in the Office of Technology Partnerships at UC Riverside, who worked with a team on this initiative for the past four years.

    Eurosemillas will obtain access to a small subset of the overall university avocado variety and rootstock collection for evaluation and testing on various continents to see if they perform as well as they do in California. At the same time, they will forge partnerships for commercialization that could lead to global market penetration of some of these selections.

    “After 31 years of working with UC on many other crops, we are delighted to partner with UCR again in a new product like avocado,” said Javier Cano Pecci, Chief Executive and Development Officer of Eurosemillas. “The avocado market is growing and is currently dominated by the Hass variety. This is a great opportunity for growers, marketers, retailers, and consumers to have options and diversify to include better avocado varieties and rootstocks adapted to their regions.”

    UC Riverside’s 70-year old avocado breeding programs house one of the most elite germplasm collections of scion and rootstock breeding material in the world. The University of California has partnered with California avocado growers since the inception of the industry a century ago and has had several plant breeders developing new varieties and rootstocks for the industry.

    Bob Bergh headed the variety improvement program for nearly 40 years, which released among other varieties, the ‘Lamb Hass’ and ‘GEM.’  This program is under the leadership of Mary Lu Arpaia, an extension horticulturist. The goal of the variety breeding program is to develop trees with high eating and market quality while increasing yield efficiency.

    Arpaia said for the California industry to remain viable, growers must have new varieties that yield more than Hass, are more tolerant to environmental stress, and can be produced reliably under high-density planting systems.

    “I am delighted by this partnership with Eurosemillas since it will help UC take this vision for the future toward reality,” Arpaia said.

    Mary Lu Arpaia, UC Riverside Extension Horticulturist

    The variety improvement program has four selections being readied for release that can augment the ‘Hass’ variety in terms of seasonality and have potential for expanded environmental adaptation within California.

    The rootstock breeding program was started in the 1940s by George Zentmyer and is currently directed by Patricia Manosalva, an assistant professor of plant pathology at UCR. The UCR Rootstock Breeding Program is one of the few well-recognized rootstock breeding programs worldwide and has been historically funded by the California industry through the California Avocado Commission. The main goal of the rootstock program is to develop and release the next generation of rootstocks that meet the most pressing needs of growers using traditional breeding complemented with genomic-assisted breeding approaches.

    The program is selecting rootstocks that can resist Phytophthora root rot, the most common avocado disease worldwide, as well as salinity, drought, and heat, all of which are expected to become worse as the climate warms. In collaboration with the California Avocado Commission, five UC Riverside advanced rootstocks exhibiting resistance to these major challenges are being evaluated by growers throughout California.

    “This partnership with Eurosemillas will allow us to test our five advanced rootstocks in combination with ‘Hass’ and local scions in other countries to determine their potential outside California,” Manosalva said.

    Peggy Mauk, director of agricultural operations and cooperative extension horticulture specialist, has been active in avocado research and extension for more than two decades. Over the past 25 years, avocado production in California and worldwide has been challenged by declining water quality. Avocado is the most salinity sensitive tree crop and ‘Hass’ is very susceptible to damage caused by salts. She initiated a program to find rootstocks tolerant to saline water.

    “Our UCR team in partnership with Eurosemillas is focused on finding rootstock/scion combinations that increase salinity tolerance,” Mauk said.

    Over the last 30 years, the avocado market has increased 2.5-fold and per capita consumption has quadrupled, generating interest in avocado production in many other countries, Manosalva said. But diseases, climate change, and the worldwide market’s dependence on the Hass variety threaten this burgeoning market.

    “The funding from Eurosemillas will allow UC Riverside to maintain the plant material and support and complement the current California Avocado Commission funding of the avocado scion and rootstock breeding programs, respectively, which have significant value given their uniqueness,” said Kathryn Uhrich, dean of UC Riverside’s College of Natural and Agricultural Sciences. — By Holly Ober, UC Riverside

  • Houston Wilson Named Presidential Director for the Clif Bar Endowed Organic Agriculture Institute

    Houston Wilson has been named the Presidential Director for the University of California’s Organic Agriculture Institute, which was established in January 2020 with a $500,000 endowment by Clif Bar and a matching $500,000 endowment from UC President Janet Napolitano.

    Wilson, a UC Riverside agricultural entomologist based at the Kearney Agricultural Research and Extension Center, joined UC ANR as assistant Cooperative Extension specialist in 2017. He will launch the institute and chart a path for future growth while also focusing on immediate priorities such as a survey of organic production in California, multiple outreach and training opportunities for growers, publication of organic production guidelines, and developing research programs. Wilson’s long-term goal is to continue to grow the endowment and position the organization to successfully support the state’s growing organic farming economy.

    “Organic growers in California face an array of interconnected agronomic, economic and regulatory challenges,” said Wilson. “Tackling these issues simultaneously requires a multidisciplinary approach to develop solutions that work in all scales of production. The economic opportunities are there, and we want to help position California growers to reap these benefits, and in doing so increase the supply of affordable organic food for consumers.”

    Since 2007, Wilson has conducted research and extension in orchard and vineyard systems with a focus on integrated pest management strategies, many of which are readily applicable to organic agriculture. Key studies have included evaluating the use of mating disruption to control navel orangeworm in fig production, cover crops to increase biological control of vineyard leafhoppers, pheromone lures to improve monitoring of leaffooted bug in almonds, and more.

    “We are excited about Houston’s vision for establishing and growing California’s first organic institute,” said Glenda Humiston, UC vice president for agriculture and natural resources (UC ANR). “Continued research advancements will be critical to the future of organic farming in our state as well as the health of our environment.”

    “Clif Bar is thrilled to see Houston’s appointment. We’ve heard from orchardists in our supply chain who have worked with him in the past and are excited that he’ll have more resources to help serve the needs of organic producers,” said Matthew Dillon, senior director of agriculture for Clif Bar. “We look forward to working with Houston, UC ANR, and the organic agriculture community to continue to improve the sustainability and economic resiliency of California farmers.”

    Wilson earned his doctoral degree in environmental science, policy and management and also holds a bachelor’s degree in international area studies, both from UC Berkeley.

    FIELD CROPS

     In Tulare County, winter grain plants were in different stages of growth, with most wheat, oats and barley coming close to maturity.  Some wheat, oats, and barley fields were being treated for weed control.  With the added rain, alfalfa continued to thrive and was growing well.  Corn was being planted.  Safflower planting was finished with most emerged.  Due to cold weather, cotton planting was behind schedule.  Rice ground preparation was ahead of schedule with ground work done in the Sacramento Valley.

     

    FRUIT CROPS

     Stone fruit orchards continued to near the end of bloom and immature stone fruit was steadily developing. Nectarines, peaches, and plumscontinued to size as expected. Cherry and pear fruit were sizing also, but still in the immature stages of growth. Pomegranates, persimmons, and grapes continued to leaf out, with warm weather boosting grape vine budding. Lemon and grapefruit harvest continued. Navel oranges, tangelo, and mandarin harvest progressed well. Tangerine groves continued to be covered with netting to prevent pollination by bees during the bloom period.

     

    NUT CROPS

    Almond development was ongoing, with a few areas predicting a more than favorable crop. Walnuts continued to awaken from winter dormancy. Pistachio leaf out remained steady with no reported issues.

     

    VEGETABLE CROPS

    Summer vegetable fields were prepared for planting.  Processing and fresh tomatoes were showing good growth.  Artichokes were harvested in San Mateo County.  Onion, garlic and parsley fields were growing well in Fresno County. Tulare County reported summer vegetables developed well with warm temperatures and adequate rains.  Strawberries were produced and grew well. Garlic, onions and peas did well under mulch.

     

    LIVESTOCK

     Recent precipitation and the week’s warming temperatures promoted range development. Rangeland and non-irrigated pasture were reported to be in good condition. Movement of cattle to spring pasture began. Some bee hives were moved to citrus orchards and to the foothills.

  • California Olive Oil Day 2020 Recap

    Roughly 150 olive oil industry members were present at third annual California Olive Oil Day held in early March.  The day started at 9 a.m. with a session focused on maximizing grower profits through grove management. Leandro Ravetti, Technical Director at Modern Olives spoke about irrigation management in olive orchards for oil production. His presentation included important information on the best times to irrigate, frequency of irrigation, and soil and plant monitoring.

    Ravetti also stressed the importance of careful site and variety selection as well as grove design prior to planting, noting that these practices can help growers increase profitability in the long term.

    William Krueger, Farm Advisor Emeritus of Glenn County, provided the group with information on canopy management in olive orchards for oil production. Krueger’s talking points included row orientation, best hedging practices to increase sunlight exposure for super high-density groves, how to prune modern high density, proper times to prune and mechanical options.

    The session on grove management was followed by Q&A with an industry panel who spoke to their own orchards and experiences. Panelists included Ravetti and Krueger as well as Lizandro Magana, Director of Farming at California Olive Ranch and Jeff Colombini, an olive grower in Lodi. The session was moderated by Adam Englehardt.

    The next session of the day dealt with disease management to prevent reduced yields and improve quality. First to present was Dr. Florent Trouillas, Assistant Cooperative Extension Specialist in the Department of Plant Pathology, UC Davis and Kearney Agricultural Research and Extension Center. Trouillas presented on the biology and control of Neofabraea in California and as well as his investigation into the occurrence and distribution of olive anthracnose in California.

    Through his research, Trouillas found that anthracnose was not present in commercial olive orchards in California. As for his research on Neofabraea, he discovered that the disease is emerging in California but remains limited to super high-density orchards at this time. This may be due to mechanical harvesting in SHD orchards, since the disease requires wounds on leaves and twigs to spread.

    Next Dr. James Adaskaveg from the Department of Plant Pathology at UC Riverside presented his research on epidemiology and management of olive knot and evaluation of new fungicides for the control of olive leaf spot/peacock spot. Adaskaveg recommended preventative care as the best means of managing these diseases. Since olive trees are most susceptible to olive knot and peacock spot at a point of injury, like that which occurs after mechanical harvesting and pruning, he recommended that trees be sprayed with a treatment the same day as the damage occurs.

    Dr. Askaskaveg also spoke about several new products that are in the process of being registered for use in California — an effort that has been made possible through research funded by the OOCC.

    During the Q&A portion of the session Adaskaveg, and Trouillas were joined by Paul Busalacchi, Director of Ag Operations at Corto and John Post, President, Agricultural Advisors to answer attendees’ questions.

    The final session featured Dan Flynn, Director of the UC Davis Olive Center who referred to California olives as “the crop of the future”. Flynn gave an update on the Olive Center as well as a recap of the year’s research. He also challenged growers to double yields by the year 2030, which some growers stated they thought was an achievable goal. His plan to help the industry achieve this included implementing a benchmark assessment of current production, conveying best practices in the New Olive Oil Production Manual and pushing higher yields through field research.

  • USDA-APHIS Impact Report: Protecting 900 Million Acres of Farmland

    The USDA seal includes the inscription “Agriculture is the foundation of manufacturing and commerce.” It’s fair to say that it is also the foundation of a stable and caring society because agriculture feeds and clothes the people. For nearly 50 years, it’s been the job of APHIS to protect American agriculture’s ability to feed and clothe the world by keeping it healthy. Every American and untold millions of people around the world benefit from healthy and profitable U.S. farms and ranches. It is my honor on behalf of over 8,400 employees, working in all 50 States, 4 territories, and 35 countries to report to you on APHIS’ accomplishments in 2019. Some of the highlights include:

    • 100 percent of the United States is now free of the plum pox virus, thanks to the work of Plant Protection and Quarantine, ending a 20-year battle with the most devastating viral disease of stone fruit worldwide.
    • Unlike those in many countries, Americans don’t have to face African swine fever and foot-and-mouth disease, because Veterinary Services ensured there were no incursions of these most devastating of foreign animal diseases.
    •  More than 700 million air passengers flew more safely because Wildlife Services protected them from wildlife strikes at more than 870 U.S. airports and military bases around the globe.
    •  Dogs in breeding operations, primates in research projects, and zoo animals all were safer and healthier because 99 percent of Animal Welfare Act (AWA) licensees and registrants are in substantial compliance thanks to inspections, guidance, and outreach by Animal Care.
    •  All Americans have a more abundant and more affordable food supply, and many others overcame devastating hardships, because more than 1,300 APHIS employees took time away from their families, homes, and regular duties to fight 38 emergency incidents like pest and disease outbreaks, natural disasters, and other threats to U.S. agriculture and health and safety.

    And that’s just a small representation of the things reflected in our 2019 Impact Report. Please consider these numbers:

    • APHIS protected 900 million acres of U.S. farmland.
    • APHIS made it possible for $137 billion in U.S. agricultural exports to move around the world.
    • APHIS helped keep 21.6 million Americans employed in U.S. agriculture, food, and related industries.

    I hope you’ll take some time to review the APHIS 2019 Impact Report to find out more about the impact of

    our work across the nation and worldwide.

     

    You can also find more information about the impact of APHIS’ work by viewing the short videos linked below. Our Deputy Administrators tell the story of an agency with many missions, but one common purpose: keeping the American people fed, clothed, and safe.
