SpraKil SK-26 Granular is a nonselective herbicide for controlling a wide range of annual and perennial weeds and grasses. It is recommended only for non-cropland areas such as railroad rights-of-way and industrial areas. 100 to 200 pound applications of SpraKil SK-26 Granular per acre usually result in a nonproductive condition of the soil for a period of a year or more. The duration of nonproductivity is dependent upon rainfall, soil type, and other conditions. Application with a spoon, a pump-feed backpack spreader or a gravity-feed backpack spreader is prohibited.
