The San Diego County Citrus Pest Control District has set area wide treatment dates. Growers should apply an effective foliar treatment to knockdown all stages of ACP.


Treatment Dates:

Pauma Valley and San Pasqual Valley May 17 to May 31. These dates are earlier than last year. Treatments are more effective when the populations are small. This will give growers greater flexibility in the event of wet weather and the dates can be shifted forward but still allow applications before the flush begins.


Treatment with an effective ACP product is MANDATORY within pest control district boundaries. Areas outside of district boundaries are strongly encouraged to participate in the coordinated treatments to aid in the effectiveness of the treatment strategy. Studies indicate a treatment rate of 90% or more is necessary for area wide effectiveness. In addition, pest control district zones that reach 90% will also receive residential citrus treatments conducted by CDFA.
