Interpretive Summary: Trunk diseases (wood-canker diseases) threaten all California vineyards due to widespread distribution of the fungal pathogens. The infections are chronic and occur each year. Trunk diseases in mature vineyards reduce yields and increase management costs to the point where the vineyard is no longer profitable. Use this guide to identify trunk diseases and inform management decisions. It is not critical to identify the specific fungal pathogen because the management practices are similar and more than one pathogen is typically present. More importantly, this guide will help you: recognize the trunk disease complex as a problem, understand the preventive practices, adopt preventive practices in young vineyards, and perform these practices at appropriate times on an annual basis.
