The United States Environmental Protection Agency (EPA) recently announced the requirement and availability of a new certified applicator training module for paraquat dichloride (also known as paraquat). Paraquat is a restricted use pesticide for use only by certified applicators. The restriction applies to mixing, loading, and applying paraquat, as well as other pesticide handling activities. Products that contain paraquat dichloride as an active ingredient may be sold under many different brand names, such as Gramoxone, Cyclone, Helmquat, and Parazone, to name a few. The active ingredient is also used in premix formulations with many other herbicides.
