China endorses toxic pesticide stand-ins
A committee of Chinese pesticide industry experts have recommended replacements for banned high-toxicity insecticides, reports the Chinese agrochemical newswire, Agronet. The national high-toxicity pesticide replacement project sought replacements for the organophosphate insecticides, methamidophos, monocrotophos, parathion-ethyl, parathion-methyl and phosphamidon. It recommended the active ingredients: methoxyfenozide and quinalphos, for use against striped rice borers ( Chilo suppressalis); fipronil for use against yellow rice borers ( Scirpophaga incertulas); silafluofen, nitenpyram and thiamethoxam against white-backed planthoppers ( Sogatella furcifera); thiamethoxam against brown-backed planthoppers ( Nilaparvata lugens), emamectin against rice leafrollers ( Cnaphalocrocis medinalis); and chlorfenapyr against diamondback moths ( Plutella xylostella). Older organophosphate insecticides have been slowly phased out in China ( Agrow No 447, p 20).
