Eutypa dieback

Eutypa dieback, caused by the fungus Eutypa lata, is a major trunk disease of grapevines. The productivity of infected grapevines gradually declines and vines eventually die.

Eutypa dieback occurs worldwide in cool climate wine regions with annual rainfall exceeding 350 mm. It is widespread in premium winegrowing regions of south eastern states of Australia and New Zealand.

Vines become infected through fresh wounds such as those made during pruning or reworking. The fungus grows slowly through the cordon and trunk eventually discolouring and killing wood. Toxins produced by the fungus cause stunted shoots.
