Prefix Herbicide is a selective herbicide formulated as an emulsifiable concentrate (EC) used for the control or partial control of certain grass, broadleaf, and sedge weeds. It is specifically designed for use in soybeans and cotton. The active ingredients are S-metolachlor (46.4%) and Sodium Salt of Fomesafen (10.2%). It can be applied as a preplant surface, preplant incorporated, preemergence, or postemergence treatment in soybeans and cotton, as well as a post-directed treatment in cotton. When handling, users must wear personal protective equipment including long-sleeved shirts, long pants, chemical-resistant gloves (barrier laminate ≥ 14 mils or Viton™ ≥ 14 mils), plus socks, and protective eyewear (goggles, face shield, or safety glasses). Avoid application during temperature inversions or when wind speeds exceed 15 mph. The product is known to leach through soil into groundwater, so use caution in areas with permeable soils or shallow water tables. Note: Sale, use, and distribution is prohibited in Nassau and Suffolk Counties, New York.
