Canola is sensitive to carryover from many herbicides. View Table 1. Recropping restrictions for residual herbicides in the Canola Encyclopedia for a list of products that could be used this fall on fields planned for canola next spring, and refer to product page of your provincial crop protection guide (ex. Alberta Crop protection Guide (The Blue Book), Saskatchewan Guide to Crop Protection, Manitoba Guide to Field Crop Protection, Ontario Crop Protection Hub) for more information.
Remember to read all notes carefully. Some cannot be applied after a certain date. You’ll find useful pointers to help in your product choice and herbicide timing.
