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 January 4-18. Borrego January 11-25 . These dates are earlier than last year. This will give growers greater flexibility in the event of wet weather. If so, the board may decide to shift the dates forward and still allow applications to happen before the flush begins. These dates are at the beginning of the year so please make sure your Operator ID with County Ag Weights and Measures is current.


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.
