I have seen a lot of chatter that Dismiss NXT will suppress torpedograss in St. Augustine. Can you apply it as a pre-emergent?
Dismiss NXT Herbicide is labeled to suppress torpedograss as a post emergent/ Ti cannot be used as a pre-emergent. There is currently not a pre-emergent herbicide labeled for it. 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.
