Invasive Pest Found on Costco Plants Forces California Department of Food and Agriculture Action to Save Vineyards
Agricultural officials are urging the public to report plants purchased at Costco due to the presence of the glassy-winged sharpshooter, a pest threatening California's massive wine industry. The California Department of Food and Agriculture states the insect can transmit Pierce's disease, a bacteria that can kill grapevines and damage other local crops like citrus. The pest can be found on plants, including those sold at selected Costco stores. To prevent widespread contamination, agricultural workers are instructing consumers to keep affected plants in their original pots and contact local agricultural commissioners. Experts warn that early detection is vital because there is no treatment for the associated disease. The economic stakes are substantial, as California produces the majority of U.S. grapes, forming a multi-billion dollar industry. The concern extends beyond vineyards, potentially harming home landscaping and ornamental plants. The immediate effort is focused on managing the spread from commercial plant purchases. Authorities stress that prompt cooperation from shoppers is necessary to contain the insect and protect California’s valuable agricultural resources from irreversible damage.
