Canola Watch quiz – Spraying

A quick quiz to test spraying windows, inversions and timing.

1. For the first four questions, match the herbicide to its window of application on canola.

What is the crop-stage window of application for Ares herbicide on Clearfield canola?
2. What is the crop-stage window of application for IMI herbicides (besides Ares) on Clearfield canola?
3. What is the crop-stage window of application for glyphosate on Roundup Ready canola?
4. What is the crop-stage window of application for Liberty on Liberty Link canola?
5. Avoid spraying during an inversion. With inversion conditions, spray mist hangs in the air and can move to land anywhere. What two weather situations hint at a potential inversion?
6. You’re wondering about in-crop spray timing. Winter annuals are large but annuals are just emerging or not emerged yet. What do you do?
