Fahrenheit Herbicide is not safe to use around desirable ornamental plants such as your knockout roses as it only for use on turfgrass areas. We recommend that you spot treat the dollarweed carefully using a non-selective herbicide such as RoundUp QuikPro.

Fahrenheit Herbicide can be used in St. Augustine, but it is not labeled for Chamberbitter. This is a very stubborn weed. Pre emergent applications with a product like Isoxaben 75 WG has proven to be the most effective way to control this weed.

Repeat applications may have to take place in order to fully kill the invaders. Please review the product label for further application information. You may contact your local cooperative extension office for additional products and recommendations for this application.
