The California Grapevine Certification Program has been based on two assumptions about leafroll disease in grapevines: that the disease does not spread significantly in the field in California and that the viruses that cause the disease are evenly distributed in infected vines. Careful testing of the Foundation Plant Materials Service vineyards at Davis using a new ELISA test suggests that these assumptions are not true. Changes in the California Grapevine Certification Program are underway as a result of this new information.
