Halo 5WDG Select™

Active Ingredient: Halosulfuron-methyl

12 x 13.5 g

Halo 5WDG Select™ is a selective herbicide for postemergence control of sedges such as purple and yellow nutsedge, Kyllinga species, and certain broadleaf weeds (see weeds-controlled chart). Can be applied to commercial and residential turfgrass and on other non-crop sites.

Halo 5WDG Select should be applied as a postemergence to turf and landscape ornamental areas where weeds are an issue and actively growing. This product is generally regarded as gentle to labeled turfgrasses, both cool- and warm-season types and they should be well established before application occurs.
