Vexis® Herbicide Granular is a selective, post-emergent herbicide that delivers excellent control of sedge and kyllinga species, plus listed broadleaf weeds. The granular formulation reduces the potential for drift or off-target application and can be applied to wet or dry turf. Labeled for use on listed cool-season and established warm-season turfgrasses, including improved varieties of St. Augustinegrass, Vexis is sold in a 2 lb. shaker can and a 15 lb. bag.
Vexis gives turf professionals an important new tool in managing herbicide resistance. Vexis contains a proprietary new active ingredient, pyrimisulfan, which is in the sulfonanilide chemical class. It is in the Weed Science Society of America’s Group 2 and the Herbicide Resistance Action Committee B class acetolactate synthase (ALS) inhibitors. For example, although Vexis is an ALS-inhibitor, it has exhibited activity against weeds that have developed resistance to other ALS-inhibiting herbicides such as sulfonylureas.
