US revises dimethoate RED (re-registration eligibility decision):
The US EPA has made some revisions to the re-registration eligibility decision (RED) for the organophosphate insecticide/ acaricide, dimethoate, in response to public comments. The Agency is specifying a maximum seasonal application rate rather than a maximum number of applications per season. It has also increased the seasonal use rates for peppers and cherries. The EPA originally required a reduction in application rates and frequencies for several crops to address concerns over exposure in drinking water and occupational risks (Agrow No 500, p 12). The latest changes to the RED are open to public comment until March 30th.
