Product Overview

Sterling Blue Herbicide provides excellent control of a wide range of annual and perennial broadleaf weeds. Contains an active ingredient that is proven to effectively control unwanted weeds after they sprout. It can control and suppress over 190 broadleaf weeds. The Sterling Blue Herbicide also targets vines in corn, fallow systems, grain sorghum, woody brush, and other crops. May be applied as a preemergence or as a postemergence herbicide until the corn reaches 36 inches high. It is fast-acting and can kill weeds in just one application. Offers control in variable tillage systems and during any type of weather for flexibility. It has a unique formula with low vapor pressure but less volatile than the generic dimethylamine dicamba salt. This powerful herbicide can control even the toughest ALS and triazine-resistant weeds.
