Metalaxyl 8% Mancozeb 64% WP chemical fungicide 57837-19-1 / 8018-01-7
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."

Uses To control diseases caused by air- and soil- borne Peronosporales on a wide range of
temperate, subtropical and tropical crops. Foliar sprays with mixtures of metalaxyl and protectant
fungicides are recommended to control air-borne diseases caused by Pseudoperonospora humuli
on hops, Phytophthora infestans on potatoes and tomatoes, Peronospora tabacina on tobacco,
Plasmopara viticola on vines, Bremia lactucae on lettuce, and downy mildews on various vegetables,
at 200-300 g/ha. Soil applications of metalaxyl alone are used to control soil-borne pathogens causing
root and lower stem rots on avocado and citrus, at 500-1500 g/ha. Seed treatments control systemic Peronosporaceae on maize, peas, sorghum and sunflowers, as well as damping-off (Pythium spp.) of various crops.
