Profine 75 Herbicide is really designed for larger applications and labeled agricultural applications. If you are using, for instance, 1 oz per acre, then that is only 0.023 oz per 1000 sq ft, which would be about 0.65 grams. For small applications on turfgrass to control nutsedge or other weeds with the same active ingredient, we suggest Sedgehammer Herbicide. You would use one small packet per gallon of water when using Sedgehammer.
