California to extend US rodenticide restrictions
The US California EPA's Department of Pesticide Regulation (DPR) proposes designating the second-generation anticoagulant rodenticides (SGARs), brodifacoum, bromadiolone, difenacoum and difethialone, as restricted materials to protect non-target wildlife. The move would restrict the use of all SGARs to certified applicators. In 2008, the federal EPA implemented distribution and package size restrictions to minimise the availability of SGARs to residential consumers rather than making them restricted-use products (Agrow No 545, p 15). However, uncertified users can still purchase and use SGARS because they are not federally restricted, the DPR notes. It has determined that SGAR exposure and toxicity to non-target wildlife is a state-wide problem requiring further use restrictions. The proposal is open to public comment until September 3rd.
