  • Asked by Gilbert from Dallas
    06/01/2019
    Q
    Can you use Fahrenheit Herbicide for Dallisgrass in Bermuda and St. Augustine grass?
    A

    Fahrenheit Herbicide is not labeled to eradicate Dallisgrass. There are a few products that will suppress Dallisgrass like Certainty Turf Herbicide. When an herbicide lists that it will "suppress" a weed rather than "control" it, it just means that the research provided from testing did not kill a high enough percentage of the weed in one application to receive a "control" approval, which is usually higher than at least 80 percent. So usually it means you need multiple applications and/or other cultural or chemical treatments to completely eradicate the weed. Dallisgrass is a weed that is notoriously difficult to eradicate quickly once it is established. The best option, once it has emerged, is to either spot spray with something like Round Up Quick Pro and re-seed because there is no product that will fully kill the Dallisgrass without killing the surrounding grass.

    Q
    Is a surfactant necessary with Fahrenheit Herbicide?
    Can't find an answer on the label. I have heard word of mouth that you do need a surfactant, but when it was sold to me, I was told that no surfactant was needed. I sprayed it two weeks ago and it hasn't killed squat.
    A
