Interpretive Summary: All vineyards in California are likely to become infected with trunk diseases (a.k.a. wood-canker diseases). The main trunk diseases are Botryosphaeria dieback, Esca, Eutypa dieback, and Phomopsis dieback. The infections are chronic and accumulate over time. Farming vines with trunk diseases becomes less and less profitable with each additional infection, to the point at which the entire vineyard must be replanted. In this way, trunk diseases significantly limit vineyard longevity. Follow this guide to identify trunk diseases in your vineyard. It is not critical to identify the exact trunk disease because the management practices are the same and because they typically occur in mixtures of one or more trunk disease. What is important is that you recognize trunk diseases as a problem, understand the preventative practices, and adopt these practices in young vineyards on an annual basis, throughout the life of the vineyard.
