Lodi, Calif.—Late pruning followed by a spray application of fungicide is considered the best strategy to prevent fungal infections of grapevines that cause Eutypa dieback and canker diseases. New biofungicide and paint products to spray onto pruning wounds and prevent fungal infections could be available in the near future. Preventing and managing Eutypa dieback and grapevine canker diseases was the topic of a forum presented by the Lodi Winegrape Commission (LWC) on July 14. A past study estimated that the costs of managing canker diseases—combined with vine losses and yield declines—amount to $260 million per year for California grapegrowers.
