REMAINING USE OF PESTICIDE ETHYL PARATHION CANCELED

EPA and the manufacturer, Cheminova, have signed an agreement to
cancel all remaining uses of the organophosphate pesticide ethyl
parathion. It is one of the most acutely toxic pesticides still
registered for use in the United States. Ethyl parathion is also one
of the most highly restricted pesticides on the market today according
to the agency's revised risk assessments. The agreement builds on an
earlier one reached in 1991 between EPA and the registrants which
limited ethyl parathion use to nine crop sites and added restrictions
to the application and post-application work practices to reduce acute
toxicity risks. Despite the restrictions, EPA's revised risk
assessments for ethyl parathion released earlier this year indicate
that high risks may remain for workers and wildlife. However, ethyl
parathion residues in food crops grown in the United States and
drinking water do not pose significant dietary risk concerns. The
pesticide has no residential uses, though some exposure may result
from spray drift. The new agreement immediately stops the use of
ethyl parathion on corn grown for seed, which poses the greatest
potential risk to workers who reenter treated fields. It phases out
use on other agricultural crops (alfalfa, barley, corn, cotton,
canola, sorghum, soybean, sunflower, and wheat) over the next three
years, ending all use of ethyl parathion in the United States by Oct.
31, 2003. The agreement also halts the import of technical grade
ethyl parathion into the United States and cancels registrations of
ethyl parathion used to manufacture other end-use pesticide products.
The registrations of the end-use products will be canceled effective
Dec. 31.
