More US registration reviews opened
The US EPA has issued preliminary work plans for a further ten pesticides entering the registration review programme. The Agency has opened public dockets for the organophosphate herbicide, bensulide, and the organophosphate insecticides, coumaphos, diazinon, dicrotophos, oxydemeton-methyl, profenofos, propetamphos, temephos, terbufos and tetrachlorvinphos. The reviews are due to be completed in 5-8 years. Most of the active ingredients were included in the EPA’s cumulative risk assessment of organophosphates, which was completed in 2006 ( Agrow No 501, p 15).
