Dismiss South Herbicide is a very specific herbicide and the label states when using it on the tolerant species of turf for weed control, you use 9.5-14 ounces per acre, which breaks down to roughly 0.220-0.331 per 1000 sq/ft. When using herbicides the amount of water you use is not what is key, only that you get the correct amount of product over the correct amount of area so as to not harm your lawn by using to much, or not see results by not using enough. The best way to measure out amount per a set gallon of water is to mark off 1000 sq/ft, walk it with just water and see how many gallons of water it takes you to cover that area. Whether its 1 or 5 gallons of water both are correct and you will mix whatever you come up with for coverage with either of the above stated rates.
Dismiss South Herbicide is labeled to control goosegrass and is safe for bermudagrass athletic fields.
Dismiss South Herbicide is not labelled for field sandbur or cocklebur. Sandburs are easier to prevent than to try to get rid of once they have invaded your yard. To prevent sandburs you should apply a pre-emergent such as Dimension 2EW or Pendulum 2G Herbicide in the late fall. For post-emergent applications, we would suggest EndRun Herbicide.
