Pre-Harvest Treatment – Product Update

Regulatory Statewide

To improve Asian citrus psyllid (ACP) suppression and prevention methods, the product Delegate WG will be removed from the list of approved pre-harvest treatments for movement of bulk citrus between regional ACP quarantine zones. Growers or grove managers currently using Delegate WG will be allowed to continue use of this product through April 20, 2018.

The California Department of Food and Agriculture made this change at the direction of the University of California, Integrated Pest Management Program (UC IPM). According to UC IPM, field studies have shown this product to be less effective than the other eligible products at achieving the ACP-free performance standard when moving citrus fruit.

The following mitigation methods are required for bulk citrus shipments from an ACP regional quarantine zone or an Huanglongbing (HLB) quarantine area.
