Roundup QuickPRO is a nonselective postemergent herbicide for commercial, industrial, non-crop and residential use. QuickPRO has two active ingredients: 73.3% glyphosate and 2.9% diquat. The addition of diquat, along with the surfactant, gives you even faster burndown. It controls broadleaf and grass weeds, or woody brush and trees - roots and all. Roundup Quick Pro is absorbed quickly by plants and is rain fast in about an hour. This super-fast dry time means rain won't wash the product away as easily and it works much faster than typical glyphosphate products. 6.8 lb jug comes with a convenient 1.5 oz measuring cap. 1.5-oz. per 1 gal. of water.
