Optimising management of eutypa dieback
July 2010 - June 2013

Summary
Eutypa dieback is a fungal disease that causes yield reduction, vine decline and eventually death of grapevines. Australian vineyards, particularly in the cooler regions, are severely affected by this trunk disease which threatens the sustainability of premium quality vines. SARDI and the University of Adelaide (UA) have a long history of research on plant disease and have become world leaders in eutypa dieback research; they currently collaborate in the Wine Innovation Cluster (WIC). This project aims to optimise wound protection for more efficient management of eutypa dieback by (i) evaluating fungicides and non-chemical alternatives to protect pruning wounds (ii) providing data to support registration or label extension of chemicals for eutypa dieback control and (iii) developing effective methods for spray application of wound protectants. Findings will contribute to the sustainability of the Australian wine industry through development and optimisation of vine health and integrated management practices. Recommending materials which are registered and improving the efficiency of applying pruning wound protection using commercial spray equipment will reduce the cost of managing eutypa dieback and increase adoption by growers.
