EPA has announced 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 EPA has taken this type of emergency action. DCPA is a pesticide registered to control weeds in both agricultural and non-agricultural settings but is primarily used on crops such as broccoli, brussel sprouts, cabbage and onions. 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.
The Emergency Order is effective immediately. EPA determined that the continued sale and use of DCPA products during the time it would take to follow the normal cancellation process poses an imminent hazard to unborn babies. While AMVAC Chemical Corporation, the sole manufacturer of DCPA, has attempted to address these concerns, EPA has determined there are no practical mitigation measures that can be put in place to allow DCPA’s continued use. EPA Administrator Regan has determined that, due to the serious and imminent harm posed by DCPA, an emergency exists such that this order of suspension effective immediately is necessary. EPA intends to issue a notice of intent to cancel the DCPA products within the next 90 days.
