Find out how many days you need to leave between pesticide application and cutting.

Our export customers have strict regulations on the types of trace residues they allow in canola. Pesticide residues in canola are detectable and tested. Protect the quality of your load and the Canadian canola industry by allowing enough time before harvest.

The Spray to Swath Interval is the minimum days between when you apply pesticides and when you can swath or straight combine your crop. On farm chemical labels, you’ll see it referred to as the Pre-Harvest Interval or PHI.
