US reviews for organophosphates
The US EPA has issued preliminary work plans for 11 organophosphate pesticides under the registration review programme. It has opened public dockets for the insecticides, acephate, chlorpyrifos, dimethoate, disulfoton, fenitrothion, methidathion, naled, phorate, pirimiphos-methyl and trichlorfon, and the defoliant, tribufos. Most of the reviews are scheduled for completion in 2014-15, with the fenitrothion review due to end in 2012. The EPA completed re-registration eligibility decisions and a cumulative risk assessment for the organophosphates in 2006 ( Agrow No 501, p 15).
