Reminder: Upcoming 2023 Fall Treatments and Information for Growers


As the upcoming fall area wide treatment windows are approaching for several counties across the state, it’s important for California’s citrus growing operations to actively engage with their local grower liaison and participate in local, area-wide or coordinated treatments to protect commercial citrus groves in the fight against the Asian citrus psyllid (ACP).

Historically, certain citrus growing regions have seen a spike in ACP detections throughout the fall season. As a result, coordinated treatments are being recommended in several counties to help mitigate this predicted surge.

For growers with operations in counties that recommend area wide treatments this fall, it is important to contact your local grower liaison or pest control district with any questions. Treatment schedules by region can be found on For more information on ACP treatments and effective materials, see the University of California’s IPM Pest Management Guidelines for Asian Citrus Psyllid.

If you suspect ACP or HLB in your grove, please notify the California Department of Food and Agriculture Pest Hotline at 1-800-491-1899.
