losses in yield and quality.
Rapid, accurate identification of diseases in the vineyard is key to preventing serious outbreaks and losses in yield and quality. Now growers can access an online guide to help recognize diseases of grapes in Eastern Canada, including downy mildew, powdery mildew, anthracnose, grey mold, black rot and crown gall. The guide contains information and colour photos of the major grape diseases, tips on scouting the vineyard for diseases, and suggestions for the management of grape diseases.
The severity of diseases varies from year to year, depending primarily on weather conditions, the history of the disease, and the susceptibility of the vines. Identifying which diseases are present each year is critical to an effective management program that provides optimal control while minimizing pesticide use.
The publication is available on the publications section of Agriculture and Agri-Food Canada’s Horticulture Research and Development Centre website: http://res2.agr.ca/stjean/index.htm.
