Late blight was responsible, in large part, for the Irish Potato Famine in the 1840âs, which resulted in the death and mass emigration of millions of people. Each year, Late blight reduces the yields of potatoes and tomatoes in the field and can cause major losses in potato tubers in storage. Late blight is found in most potato and vegetable growing regions of Canada and North America. Major outbreaks occur occasionally in Alberta (the last one was in 1993).
