Trunk Neglect Is Too Common

May 23, 2014

Trunk or wood-canker diseases, including Botryosphaeria dieback, Esca, Eutypa dieback, and Phomopsis dieback, present a serious challenge to winegrape growers. Many vineyards in California are likely infected and yield losses in severely symptomatic vineyards can reach more than 90%. The overall economic impact of losses to Eutypa alone just in California has been estimated at 14% of gross producer value.
