Eutypa dieback causes branch death and cankers on grapevines and fruit trees. You see sunken cankers and wilting of tissues beyond infection. The disease enters through pruning wounds. Prune in dry season and maintain good wound closure.
Start with cultural controls: remove infected tissue, improve drainage and air circulation, and keep foliage dry when possible. Eutypa Dieback responds best to early intervention, so scout regularly during the growing season and act at the first sign of symptoms. Chemical controls exist for severe cases but work best as preventive treatments before infection takes hold.
