Paraquat
Return to Herbicide Injury
Paraquat (Gramoxone) is a widely used nonselective contact kill herbicide that is used in burn-down applications or as a post-emergence directed spray to rows. Common injury symptoms include a white “burn” spot where the herbicide has made contact with the plant.

Management:
- For post-emergence applications, use a shielded sprayer and avoid spraying
when plants are less than 10 inches tall.
