Abstract

First report of Eutypa lata causing dieback of grapevines (Vitis vinifera) in Chile.

Abstract

In January 2016 and December 2017, several grape cordons (n = 20) with cankers and dead arms were sampled from 2 commercial vineyards (cv. Cabernet Sauvignon) in the Maule Region in Chile and were observed with wedge-shaped necrosis when cut in cross-section. The causal pathogen was isolated and identified as Eutypa lata based on morphological, molecular and pathogenicity analyses. This is thought to be the first report of E. lata associated with grapevine trunk disease in Chile.
