  • Citrus Research Board to Host Webinar Series

    The Citrus Research Board (CRB) is preparing to host the 2026 Citrus Growers Educational Webinar Series. CRB will be holding two one-hour webinars, scheduled for June 9 and 23, which will highlight research and discussions for growers.

    The first webinar, “Plant Growth Regulators and California Citrus — Review and Updates,” will review the plant growth regulators (PGRs) currently available to the California citrus industry. This will include uses and effects of each of the PGRs covering both a historical perspective and current needs. The importance of 2,4-D timing will also discussed with respect to the premature fruit drop observed in Fall 2025.

    Registration for the June 9 webinar can be done here.

    The second webinar, “On the Ground with CA-CRaFT,” was started by California Research and Field Trials in 2023 to develop practical, field-based ACP management strategies under real commercial conditions across California. A major focus of this webinar will be updates on canine-assisted Asian citrus psyllid (ACP) inspections, field scouting, tap sampling, sticky traps and drone imagery are being integrated to support regional ACP management decisions and strengthen early detection efforts. Additional updates will include planned expansion of CA-CRaFT activities into Ventura County with stronger emphasis on biological control using self-release Tamarixia radiata cage systems. Ongoing Argentine ant management efforts will also be discussed, as invasive ants continue to be an important factor Tamaraxia establishment and overall biological control success in California citrus.

  • Argentine Ant Inhibits Biocontrol Options for Deadly Citrus Pests

    Growers want to minimize their pesticide use in the orchard; but when you have invasive pests like the Argentine Ant protecting aphids and psyllids from natural predators, your options are limited.  Watch this brief interview with Greg Simmons from the USDA-APHIS as he explains and read more about it in California Fresh Fruit Magazine.

  • CA Red Scale Resurfaces in Citrus Due to Asian Citrus Psyllid Treatments

    With the threat of the deadly Huanglongbing citrus greening disease coming to the state, California citrus growers are doing all they can to keep the disease vector asian citrus psyllid out of their orchards; however, these treatments are also taking out natural enemies for red scale, causing a resurgence of the pest in California orchards.
