25th Annual Southwest Crop Diagnostic Days

July 3rd & 4th, 2019


A co-operative effort between: Ministry of Agriculture, Food and Rural Affairs; University of Guelph Ridgetown Campus; and The Southwest Soil & Crop Improvement Associations.

Providing "hands-on" learning experiences

The diagnostic day is designed specifically to improve the problem solving skills of seed, fertilizer and chemical industry personnel and agricultural consultants.

The Diagnostic Day is an annual event that highlights current topics of interest. The goal of the day is to provide quality, state-of-the-art training in all aspects of crop production and management.

The Southwest Crop Diagnostic Day provides agribusiness personnel with hands-on learning experiences to assist in the correct identification and treatment of crop problems common to southern Ontario. The program provides a real-world environment where agriculturists can hone their crop trouble-shooting skills and evaluate new and alternative managment strategies.

To facilitate discussion with speakers, participants will be broken into small groups of approximately 20 people. Each group will rotate through the ten stops.

Staff from the Ontario Ministry of Agriculture, Food and Rural Affairs, University of Guelph Ridgetown Campus and Agriculture and Agri-Food Canada will conduct the sessions.
