Since the first recognition of trunk and canker diseases more than a hundred years ago, the general problem of vine dieback and collapse is becoming more clear. This seminar is an overview of the early history of vine dieback and dead arm symptoms that led to Eutypa dieback and Bot canker identification and current investigations of both canker diseases. Recent research of Esca, Young Vine Decline and Measles will also be presented. This seminar will provide a better understanding of these diseases and several newly identified pathogenic species that can infect the permanent woody tissues, causing loss of productivity and eventual vine collapse.
All speakers in this session have been invited. Keynote speakers are identified with an asterisk (*).
