I spot spray mainly for Leafy Spurge, Curlycup Gumweed, Spotted Knapweed, and Whitetop. I use a 14 Gallon Sprayer in the back of my ATV, spot spraying.
GrazonNext HL Herbicide is not labeled to treat leafy spurge or whitetop. The labeled rate for knapweed and gumweed is 24-34 ounces of GrazonNext HL Herbicide per acre.
