Sprakil SK-26 Granular is a nonselective herbicide for controling 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 300 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 nonporoductivity is dependent upon rainfall, soil type, and other conditions.
