I have a St. Augustine lawn in South Carolina with a major infestation of Florida betony. If choosing between Fahrenheit and Celsius WG, which one is least likely to harm the grass? I used a product containing 2,4-d in the late fall and it damaged my lawn.
Both Fahrenheit Herbicide & Celsius WG Herbicide are labeled for Florida betony while being labeled safe for St. Augustine. Just make sure you check the label for correct rates, do not apply during the hottest time of the day, and do not apply when lawn is stressed.
