Important Changes for Using Paraquat

The U.S. Environmental Protection Agency (EPA) has required that by November 14, 2019, Paraquat manufacturers must make several changes to the product label.  These changes will impact all users of Paraquat.  The primary changes include:  both English and Spanish language versions of warnings printed on the label, as well as a revised restricted-use statement; and the requirement for U.S. EPA-approved training in addition to restricted-use materials certification by the state.  It is important that you are in compliance by November so as not to affect your farming operations.

Just a reminder, if you have any Paraquat products with the current/“old” label you are fine to use that product as you are now, following all label instructions, until November of 2020.
