Costco Warns Desert Willow Buyers of Pest in Plants Sold June 24-July 3

3 articles · Updated · MyNorthwest · Jul 13

Summary

  • Costco told customers that desert willow plants bought between June 24 and July 3 may carry glassy-winged sharpshooters, an invasive leafhopper that spreads Pierce’s disease and can kill grapevines.
  • The retailer urged buyers to isolate the plant, keep it in its original pot, avoid planting it or throwing it in trash or compost, and double-bag it if possible.
  • Costco said customers should not return the plant to stores; instead, they can get a full refund by presenting the warning letter at a nearby warehouse.
  • The alert follows a Napa County warning two months ago that 63 of 220 grapevines shipped to Costco in Napa were infested, underscoring risks to California agriculture.
  • A 2008 University of California study cited by ABC found Pierce’s disease caused nearly $30 million in losses and destroyed more than 1,000 acres of Northern California grapevines from 1994 to 2000.
