In California, HLB has not been confirmed in commercial citrus groves, but the Asian citrus psyllid has been found.
There is ongoing cooperation between the Florida and California industries to do everything possible to avoid the infection from being confirmed in California commercial production. Stakeholders in the California citrus industry attended the International Research Conference on Huanglongbing that was held in March in Florida. While there, the group also toured groves and visited with growers.
“Look at the major
transport routes of commercial citrus from grove to packing plant in California, and that is where you’ll also see psyllid detections,” says Steve Olson, product manager with Bayer. “Quarantine zones have been put in place, and they are in the process of passing regulations to use tarps and other methods to control the spread of Asian citrus psyllid.”
To help protect the commercial citrus industry, Bayer and California Citrus Mutual have run a program, Citrus Matters which includes the Abandoned Citrus Tree program. This provides resources for tree removal and destruction for backyard trees that pose a threat to commercial citrus.
