The U.S. Environmental Protection Agency is announcing the emergency suspension of all registrations of the pesticide dimethyl tetrachloroterephthalate (DCPA or Dacthal) under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA).
This is the first time in almost 40 years the EPA has taken this type of emergency action.
DCPA is a pesticide registered to control weeds in both agricultural and non-agricultural settings. DCPA is currently undergoing registration review, a process that requires reevaluating registered pesticides every 15 years to ensure they cause no unreasonable adverse effects on human health or the environment.
In deciding whether to issue the emergency order, the EPA consulted with the U.S. Department of Agriculture to understand how growers use DCPA and alternatives to this pesticide.
