sulfanilamide and other metabolites; the poorly characterised nature of the impurities potentially present in the
technical-grade product; toxicity to birds. This decision is given in with Regulation (EC) No 1107/2009 of the European Parliament and of the Council concerning the placing of plant protection products on the market, and amending Commission Decision 2008/934/EC. ==References==
