LIBERATOR 650 is a non-selective residual herbicide used to control a wide range of annual and perennial weeds and grasses in non-cropland areas. The application of 200 to 300 pounds of LIBERATOR 650 per acre usually results in a non-productive condition for a year or more. The dust-free, granular formulation is ideal for full-season control with county road departments, parks and recreation departments, schools, public buildings, industrial sites, golf courses, airports, etc. *(EPA)
