SAFETY FIRST: New label requirements by EPA for applicators of paraquat herbicide are driven by the need for safe handling and use.

New training required to apply paraquat

EPA now requires new certified applicator training for users of paraquat herbicide.

The U.S. Environmental Protection Agency recently announced the requirement and availability of a new certified applicator training module for paraquat dichloride.

Paraquat herbicide is classified by EPA as 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 are sold under different brand names, such as Gramoxone, Cyclone, Helmquat and Parazone. The active ingredient is also used in premix formulations with many other herbicides.

Kristine Schaefer, program manager for the Pesticide Safety Education Program at Iowa State University Extension, provides the following information.

Special safety training now required

According to EPA, the reason for this new training requirement and other new restrictions is to help reduce accidental ingestion (a single sip can be fatal) and other exposures to the product. Since the 2000, 17 deaths have resulted from accidental ingestion of paraquat. Many of these deaths were a consequence of people illegally transferring the pesticide to empty beverage containers and the victim later mistaking it for a drink.

In addition to the deaths by accidental ingestion, since 2000, three more deaths and many severe injuries were caused by the pesticide getting onto the skin or into the eyes of people working with it. To help prevent these tragedies, certified applicators must now take paraquat-specific training before use.

The training emphasizes that the chemical must not be transferred to or stored in improper containers. Also covered will be paraquat toxicity, new label requirements and restrictions, consequences of misuse, and other important information.

Other label changes and restrictions

Companies are required to have newly labeled product in the market after Nov. 14, but some may produce and sell the newly labeled product before that date. When purchasing the newly labeled product, keep in mind that the product may only be mixed, loaded or applied by a certified applicator who has successfully completed the EPA-approved training module before use.

The requirement for training is only one of several actions EPA has taken to prevent poisonings, including making label changes, restricting the use of all paraquat products to certified applicators, and requiring closed-system packaging for all non-bulk (less than 120 gallons) end-use product containers of paraquat.

EPA is allowing the sale of paraquat that is already in the channels of trade, so some paraquat sold this growing season may not have the new training requirement on the label. However, if the new training requirement is listed on the label of the product they purchase, applicators must complete the training.

Also, applicators that currently have a supply of paraquat that does not have the new labeling listing the required training are not required to complete the training.

Pesticide registrants had to submit label changes and new product registrations for the closed system packaging by March 30. They will have 12 months from EPA’s label approval date to adopt the closed system packaging.
