Paraquat is the active ingredient in several popular herbicide formulations used in Georgia (Firestorm, Gramoxone, Helmquat, and Parazone).  It has multiple uses including preplant burndown applications, early-postemergence weed control in peanut, and as a soybean harvest-aid. 

Paraquat registration has been under review by the EPA and many changes will be occurring in the very near future.  The main reason for these changes is that many people have died over the years from ingesting paraquat that was improperly stored in various types of containers (cans, plastic bottles, cups, etc.)   

The following table of future changes was provided to me by Syngenta (the purveyors of Gramoxone) and these dates are subject to change:
