Anyone using products containing paraquat (Gramoxone and all other generic formulations) must now complete an EPA-mandated training before application. Here are some important points:
Only certified applicators, who successfully completed the paraquat-specific training, can mix, load or apply paraquat.
Application “under the direct supervision” of a certified applicator is no longer allowed. Registered technicians cannot apply.
Restricts the use of all paraquat products to certified applicators only.
Applicators must repeat training every three years.
The EPA website has the required training. For those who are unable to do the training online, EPA will have a non-web-based training format available.
Refer to the EPA paraquat website for more information and frequently asked questions.
In addition to the training, EPA requires that paraquat products be contained in a closed system. Over the next year or so, manufacturers will begin placing special lids on 2.5-gallon jugs and a necessary adaptor/receptacle will need to be installed on your sprayer in order to pour this herbicide into the sprayer tank.
These new jug caps cannot be removed or opened by hand. Mini bulk tanks will also have special connectors on hoses to maintain a closed system into the sprayer tank. More details will be released once these lids and adaptors become more widely available.
