AC-50W Root Inhibitor
AC-50W contains a powerful root growth inhibitor that may be added to Avanti’s soil stabilization and water control grout systems. Its low (20 ppm) solubility in water extends its effectiveness because the initial dosage is released slowly. Above-ground vegetation is unaffected by the root inhibitor in the grout. Dichlobenil is a specific, non-systemic growth inhibitor functioning only in the area of the treated soil by forcing the root to travel elsewhere for its water supply. After removing the roots with a chemical root control program or via mechanical means, many contractors use AC-50W to prevent future root growth while effectively stopping infiltration.
