If it dries up long enough to apply post emerge herbicides on cotton, below are a few tips on minimizing injury from topical herbicides.

1. Avoid heavy dew (pooling when spray) on cotton plants.
2. Avoid extreme conditions (wet, dry, cold, hot).
3. Avoid “Thripy” cotton.
4. Additional additives (other than those labeled) will increase injury without improving weed control.
5. Apply proper GPA; low GPA may increase injury.
6. Succulent growing cotton is more sensitive.
7. Cotton growth stage is the greatest factor influencing injury; younger cotton, 1- to 7-leaf, is often injured less than older cotton, 8- to 15-leaf.
