Costco Customers Urged To Check Desert Willow Plants For Invasive Pests

SAN DIEGO, CA — San Diego County agricultural officials urged Costco customers who purchased a desert willow plant from the retailer between June 24 and July 3 to inspect it after invasive agricultural pests were found on plants shipped from a Texas nursery.

The affected plants may contain the broad-headed sharpshooter, which is not established in California, or the glassy-winged sharpshooter, which is already present in the state. Officials said both insects can spread Pierce's disease, a plant disease that has caused millions of dollars in losses to California's wine grape industry and threatens vineyards, orchards, nurseries and home gardens.

The plants were distributed to Costco warehouses throughout California, including seven locations in San Diego County.

County officials said about 200 plants sold in San Diego County remain unaccounted for. Costco is contacting customers who purchased the plants, and the county has already received several inquiries.

Customers who have not yet planted the desert willow should double-bag the plant, seal both bags and dispose of it in the regular trash. Officials said the plants should not be placed in green waste, returned to Costco or moved to another location.

Customers who have already planted the plant should contact the county's Department of Agriculture, Weights and Measures. Agricultural inspectors will examine the plant and provide guidance on next steps.
