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.
