UKVA Bulletin No. 50 - Grapevine Trunk Diseases - Nov 2011

The aim of this bulletin is to summarise the most important areas covered at the Wineskills workshops on trunk diseases, and then to provide growers with guidelines to attempt to control spread. These suggestions have come from various sources, primarily the literature of, and communication with, overseas experts. We do not claim to be experts on trunk diseases, but we are raising awareness of the problems; previously no guidelines were available. Growers follow these suggestions at their own risk. Botryosphaeria canker (Botryosphaeria); Black foot (Cylindrocarpon); Petri disease, previously called Black Goo (Phaeoacremonium and others)
