Two surveys addressing trunk injury and trunk diseases were undertaken in 2019 in Minnesota and New York. The Minnesota survey focused on identifying trunk pathogens and their impact in the upper Midwest. In the New York survey, we quantified the extent of missing grapevine canopy due to dead arms, missing vines, and visible Eutypa, and Crown Gall symptoms by examining 300 vines in 60 vineyard blocks. Percent canopy reduction in hybrids ranged from 0.5 to 26% (median=5%) and in vinifera ranged from 1 to 70% (median=10%). We will discuss management options for addressing trunk injury.
