1 Under certain conditions, application of Quinclorac 75DF Select made to annual grasses at 2 to 4 tiller may not provide complete control. A sequential application will be required for grass control in these situations. Optimum control is achieved when applications of Quinclorac 75DF Select + methylated seed oil are applied either before second tiller or as weed grasses mature.

2 Tank mix partner or sequential application required.

3 Make 2 sequential applications of 0.245 oz. (0.50 lb. AI/A) of Quinclorac 75DF  Select per 1,000 sq. ft. and an additional sequential application up to 0.90 fl. oz. (0.46 lb. AI/A) of Quinclorac 75DF Select per 1,000 sq. ft. at 14- to 21-day intervals.

4 Biotypes of large and smooth crabgrass in California have shown varied response to Quinclorac 75DF Select. If control failure occurs following a full or split application, DO NOT reapply Quinclorac 75DF Select. Change to a herbicide with a different mode of action.
