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 costs the Australian wine industry millions of dollars in lost production and additional vineyard costs per annum. Vineyard owners can manage the disease by physically removing infected wood and encouraging shoots from lower, uninfected parts of the vine. Wound treatments should be applied post-pruning to reduce likelihood of new infections.
