Evaluation of Northern Grape Hybrid Cultivars for Their Susceptibility to Anthracnose Caused by Elsinoe ampelina

O. Carisse and A. Lefebvre

August 2011

Research

Use of winter-hardy grape cultivars has enabled expansion of wine grape production in the province of Quebec, Canada, but some of the cultivars have been reported as susceptible to grape anthracnose, a serious disease. On susceptible cultivars, anthracnose management is costly, making grape production unprofitable. Therefore, this study was conducted to evaluate the susceptibility of winter-hardy grape cultivars suitable for northern climates to anthracnose. It was expected that the research would facilitate informed choices among cultivars as new vineyards are established in the province of Quebec.
