Duke’s Root Control does it all, providing the best chemical root control product available, applied by the most professional crews in the industry. Razorooter® II is the only diquat-based herbicide registered by the U.S. Environmental Protection Agency (EPA) for controlling nuisance tree roots in sanitary sewer line collection systems and received a classification of “evidence of non-carcinogenicity for humans” (USEPA Diquat R.E.D. Facts, July 1995). In 2014 the EPA further approved an amendment of Duke’s diquat dibromide labels to lower the signal word from “warning” to “caution.” Our crews insert a hose from manhole to manhole, preparing to fill the affected sewer pipe with Razorooter II. The foam is then released, compressing against pipe surfaces, penetrating cracks, joints and connecting sewers. Roots are killed on contact, decay naturally and slough away. Duke’s applications prevent root-related stoppages for 2-3 years. We guarantee it. Visit us in booth # 1048, at www.dukes.com or call 800-447-6687.
