Will grazonnext hl kill blackberries in pasture? My tank sprayer applies 25 gallons per acre. How much Grazon should I put in 25 gallons of water? Should I add any other chemicals? If so what and how much?
GazonNext HL Herbicide is labeled to suppress blackberry. Label states rates range: 1.5 to 2.1 pints (24 to 34 fluid oz) product per acre when treating for blackberry suppression. The addition of a high quality non-ionic surfactant (of at least 80% active ingredient) at 0.25 to 0.5 % volume per volume (1 to 2 quarts per 100 gallons of spray) is recommended. you may use a surfactant like Non-Ionic Surfactant for Herbicides.
