Section 2.2: Vineyard Suitability for Grafting – Trunk health & suitability

A cross section cut through a trunk beginning from the highest point and becoming lower until ground level will expose trunk disease symptoms. The level of disease incidence (number of vines/Ha) and severity (degree of infection) will have an impact on the short and long term visibility of grafting.  The older the trunk the greater the likelihood that there will be some level of trunk disease infection. The main trunk disease in Australia is Eutypa lata followed by Botrysphaeria.  Spring monitoring for Eutypa lata (EL) the season prior to beginning … Continued
