White powder 57837-19-1 Metalaxyl Plant Fungicide / Natural Garden Fungicide





Metalaxyl is a systemic, benzenoid fungicide used in mixtures as a foliar spray for tropical and subtropical crops, as a soil treatment for control of soil-borne pathogens, and as a seed treatment to control downy mildews. Experimental-use permits are in effect authorizing the application of metalaxyl on some food crops, although tobacco, ornamentals, conifer, and turf applications are the major uses. Smokers could be exposed through inhalation. Products containing metalaxyl must bear the signal word "Caution."
