MSU Pesticide News - March 12th, 2019
Cecil Tharp, MSU Pesticide Education Specialist
In a previous MSU news release, the U.S. Environmental Protection Agency (EPA) announced its final decision regarding pesticide products containing the herbicide active ingredient, paraquat (Table 1). This was due to increased human health concerns.
In summary, EPA has ordered the following measures to adequately protect applicators and the public:
- Label changes emphasizing paraquat toxicity.
- Restricting use of paraquat products to certified applicators only.
- Closed-system packaging for all non-bulk (< 120 gallon) end use containers of paraquat.
- Mandatory EPA approved paraquat training for all individuals mixing, loading or applying paraquat.
As part of these requirements, paraquat products purchased with new label language, including mandatory paraquat trainings, must attend an EPA approved paraquat training prior to mixing, loading or applying. All paraquat labels distributed by manufacturers are expected to include a link to the training by the fall of 2019.
An online paraquat training is available, created by pesticide manufacturers and approved by the EPA. This training provides information about paraquat’s toxicity, personal protective equipment, new label requirements, restrictions, and the consequences of misuse. Applicators must print out certificates online and retain for their own records. In addition, the National Pesticide Safety Education Center (NPSEC) will retain certification records as well.
