When selecting a field to grow mustard, particular attention should be paid to the previous use of herbicide and any applicable re-cropping restrictions. The list of products and the length of cropping restrictions can be found in the following table. Be sure to cross-reference with the product label as well as the current Saskatchewan Agriculture Guide to Crop Protection for the most up-to-date information. Note that some products may have additional considerations for certain years during or following excessively dry conditions; make sure you are aware of increased carry-over risk for products used prior to the mustard crop. If applicable, products will include details about moisture thresholds and additional re-cropping restrictions.
