When transitioning from burnoff to in-crop spraying of herbicides or switching from one crop to another, sprayer operators are reminded to clean out sprayers properly. Residues of herbicides, particularly Group 2 herbicides, that are left in the tank may settle, dry or precipitate on tank walls and plumbing and may be more difficult to remove if not cleaned until a later date.
Adjuvant systems used in in-crop herbicides used in canola are very effective tank cleaners and will remove the smallest residue of herbicide remaining in the tank and deposit it in your sensitive canola crop.
