One of the leading causes of herbicide injury in canola is insufficient sprayer cleaning, says Clark Brenzil, provincial weed control specialist for the Saskatchewan Ministry of Agriculture.
Whether due to drift or residue, herbicide injury can result in drastic yield losses, besides being an eye-sore to drive by.
When Brenzil joined us for a Canola School last, he spoke of distinguishing between herbicide injury, specifically as it related to Liberty and group 2 products. He suggested group 2 injury is often a result of contamination within the spray tank. In this video, Brenzil talks about how and when a sprayer should be cleaned, highlighting a few misconceptions along the way.
