FALL 2021 TREATMENT PERIOD ANNOUNCED

Recently the first case of an HLB infected tree was discovered in San Diego County near Oceanside. ACP was first detected in our county in 2008. The first HLB positive tree was found in Hacienda Heights in 2012. We made it 13 years without any positive finds in our county. Unfortunately, now the disease is here, and so far 4 positive trees have been removed near the find.

We believe that the efforts made by growers, local Ag Commissioner’s offices, CDFA and USDA made it possible to get this far without a positive find. Now that we have HLB in the county it is more important than ever to keep ACP populations as low as possible. At this time coordinated treatment is the only method that reduces the risk of spread significantly.

Ag Weights and Measures (AWM) will be working with residents and businesses within the HLB quarantine boundary to prevent plant material or fruit from moving out of the area. Sandra Zwaal will be providing support in her role as the CDFA Grower Liaison. There are a few commercial groves that fall within the quarantine. So far none of the properties within the pest control district are part of the quarantine. If so, additional measures would be needed to harvest and move the fruit out of the area.

We need all the growers to work in coordination to suppress the ACP population as much as possible. This is happening on the eve of our Fall Coordinated Treatment Period. If you are in the San Pasqual or Pauma Valley growing area, please treat your groves between Aug 30 and September 13, 2021. If your grove is in the Borrego growing area, please treat the trees systemically between September 1 and September 15 or a foliar treatment from October 1 to October 15.

Fall 2021 Area Wide Treatment Dates for Pauma Valley, San Pasqual and Borrego

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. If a grower feels systemic treatments work on a particular property then the foliar treatment can be supplemented or replaced by the systemic treatment.

Treatment Dates:

Pauma Valley and San Pasqual Valley August 30- September 13

Anza Borrego September 1-15 systemic, October 1-15 foliar

*Organic operations must do 2 applications within 10 days of each other.

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.
