US EPA acts on unsupported inerts
The US EPA is to remove five inert ingredients from its list of inerts approved for use in agrochemical products. The move follows the failure of manufacturers to provide data under the endocrine disruptor screening programme. The Agency issued endocrine test orders to producers of nine inerts in 2010 ( Agrow No 579, p 15). Companies agreed to develop data for acetone and isophorone but there was no support for seven inerts. The EPA plans to issue new test orders for di-sec-octyl and phthalate as they meet testing criteria under the Safe Drinking Water Act. However, it has no plans to issue further orders for methyl ethyl ketone, butyl benzyl phthalate, dibutyl phthalate, diethyl phthalate or dimethyl phthalate and will no longer approve their use in pesticides.
