Crop Diagnostic Services

Lab Services

Looking for help identifying diseases, weeds and insects of agricultural and horticultural crops?

Your local Manitoba Agriculture Office can help you diagnose the problem. For more complex issues, they can connect you to the laboratory services of the Crop Diagnostic Centre. The purpose of the Crop Diagnostic Lab is to provide extension diagnostic results for agricultural crop production and data to compliment the surveillance for pests completed by Manitoba Agriculture staff. A $10.50 service fee will be charged for all non-agricultural samples (includes home garden produce, ornamental plants, trees in home yard and lawn grass).

Samples can be submitted at your local Manitoba Agriculture office or at the reception desk at 545 University Crescent, Winnipeg, MB. When submitting, all samples need to be accompanied by a Crop Diagnostic submission form. The following forms are fillable and can be printed to include with your submission.

Insect-Weed Identification Form (136 KB pdf)

Disease-General Diagnostic Form (139 KB pdf)

Results from the lab submission will be received within 10 working days, from when the sample was received at the lab. Samples submitted at a rural Manitoba Agriculture office will take longer to have results received, due to transportation time.

Results are for basic and visual diagnosis only. Molecular results or specifics to a species level for weeds, insects and disease causing  agents cannot be guaranteed. 

Legal land description or town location where the sample was collected, must be included on the form when submitting samples for analysis.  If location is not included, the submitter will be contacted for that information. Without legal land description or town information, the sample will not be analyzed.
