Eutypa Dieback - Spring Identification Pictures.

Eutypa and other trunk diseases have been identified as causing significant problems in South Australian vineyards. This season appears to be a 'big' year for Eutypa symptoms.

Eutypa is present in many vineyards- of all ages. The fungus grows slowly in the wood and produces foliar symptoms several years after the initial infection. Pictured below is a 10 year old vineyard in the Sellicks Foothills demonstrating that Eutypa can be found in 'young' vines.

Eutypa dieback foliar symptoms are are most obvious in spring when shoots are 30-70 cm long.


Eutypa infection reduces bunch numbers and reduces vine yield.
