  • Are Tree Nut Growers Doing Their Part to Manage Navel Orangeworm?

    Winter sanitation, mating disruption and proper pesticide application — all critical strategies in managing the number one pest of tree nuts: Navel Orangeworm. No one wants this pest on their farms, but are growers really doing their due diligence in managing this pest with tools that are now widely available to the industry?  Watch this interview with Bob Klein from the California Pistachio Research Board as he shares the rough statistics and read about how you can do better in Pacific Nut Producer Magazine.

  • Keeping Up with the Evolving Navel Orangeworm Pest Pressure

    So how bad can Navel Orangeworm damage get in our tree nut orchards? Hopefully we won’t have to find out this season, as growers are equipped with more tools and practices to control the pest. Watch this brief interview with Research Entomologist Joel Siegel as he shares some evolving trends in pest pressure across the state, and read more about it in Pacific Nut Producer Magazine.

  • What You May Not Know About the Pierce’s Disease Glassy-Winged Sharpshooter Control Program

    It’s getting to be time soon for California grape growers to vote on the continuation of the Pierce’s Disease Glassy-winged Sharpshooter Control Program. You may not feel that Pierce’s Disease is a threat to your vineyard, but other pests and disease are.  Watch this brief interview with Michael Miiller from the California Association of Winegrape Growers as he shares about some new pests and diseases covered under this program that may soon otherwise become a threat to your vineyard.  Read more about it in American Vineyard Magazine.

  • PD/GWSS Board Designates Spotted Lanternfly as a Pest of Winegrapes

    The Pierce’s Disease and Glassy-Winged Sharpshooter (PD/GWSS) Board officially added the spotted laternfly (SLF) to its list of designated pests and diseases, making it eligible for research and outreach funding.

     

    “The best quarantine efforts happen at the points of origin. By showing that this is a pest we don’t want in California, we have a better chance of getting cooperation and action to control its spread,” said Roger Spencer, Pierce’s Disease Control Program acting statewide coordinator.

    The SLF, a native to Asia, was first detected in Pennsylvania in 2014. It is spreading rapidly and the PD/GWSS Board has been closely following the situation. The pest is primarily known to feed on the tree-of-heaven, but has a wide host range including grapes. It is considered a high risk pest due to its mobility, with eggs and adults easily transported long distances by normal trade and transportation activities, making it a concern for grape growers nationwide.

  • Federal Government Invests $6 Million to Combat Formidable Tree Nut Pest

    California tree nut growers received a ‘holiday gift’ from the Federal Government last week — to the sum of $6 Million in appropriation funds to combat the formidable pest of the tree nut industry, Navel Orangeworm.  Watch this brief video with the Executive Director of American Pistachio Growers Richard Matoian for more details.

  • Pesticide Use Notifications Near Schools: Correcting Common Mistakes

    By now, most farmers know the regulations regarding pesticide use notifications near school sites; however, many are still getting fined by the counties for violation of this rule. So where are farmers coming short? Watch this brief interview with Travis Howard from the Sonoma County Ag Department as he clarifies some important dates and requirements farmers need to know about to stay safe.

  • Detection of Citrus Disease Huanglongbing Triggers Quarantine Expansion in Portions of San Bernardino and Los Angeles Counties

    A quarantine has been declared following the detection of the citrus disease Huanglongbing (HLB), or citrus greening, in a single citrus tree in an unincorporated area of San Bernardino County, near Montclair. This is the first time the plant disease has been detected in San Bernardino County. CDFA is working with the United States Department of Agriculture (USDA) and the San Bernardino County and Los Angeles County agricultural commissioners on this project.

    The 93-square mile quarantine area will link up with existing quarantines in Los Angeles and Orange Counties, creating a contiguous 1,015-square-mile area. The new portion is bordered on the north by I-210; on the south by Chino Airport; on the west by Highway 57; and on the east by Ontario International Airport. HLB quarantine maps for San Bernardino and Los Angeles counties are available online at: cdfa.ca.gov/plant/hlb/regulation. Please check this link for future quarantine expansions in these counties, should they occur. Quarantines are already in place for HLB in portions of Los Angeles, Orange and Riverside counties.

    The quarantine prohibits the movement of all citrus nursery stock or plant parts out of the quarantine area. Provisions exist to allow the movement of commercially cleaned and packed citrus fruit. 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 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.

    HLB is a bacterial disease that affects the vascular system of citrus trees and plants. It does not pose a threat to humans or animals. The Asian citrus psyllid can spread the bacteria as the pest feeds on citrus trees and plants. Once a tree is infected, there is no cure; the tree will produce bitter and misshaped fruit and die within a few years.

    CDFA staff have scheduled removal of the infected tree and are in the midst of a treatment program for citrus trees to knock down Asian citrus psyllid infestations within 400 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 surrounding citrus from this deadly disease.

    CDFA, in partnership with the USDA, local county agricultural commissioners, and the citrus industry, continues to pursue a strategy of controlling the spread of the Asian citrus psyllids while researchers work to find a cure for the disease.

  • Finding Truth & What to Do Amidst the Controversy Over Crop Protection Materials “Pesticides”

    Agriculture and the science of crop protection materials is too often misunderstood by the public and is under constant attack by extremists in the political arena. As legislation and jurisdiction begins to more commonly ignore sound science in their decision-making, farmers are rightfully concerned about the future of agriculture and what may or may not be in their power to make a difference in protecting their freedom to utilize these valuable tools.  Watch this brief interview with Jay Vroom, former CEO of CropLife America as he shares some insights.
