US tightens fumigant controls
The US EPA is tightening restrictions on aluminium and magnesium phosphide pesticides used in rodent burrow fumigation. The move prohibits use in residential areas and expands buffer zones around non-residential buildings that could be occupied by people or animals. The technical registrant, Degesch America, has agreed to provide new product labels by May 1st. Only about 20% of the company’s aluminium and magnesium phosphide stocks are intended for rodent burrow control. The fumigants are mainly used for insect control in stored commodities.
