Metalaxyl is a systemic fungicide with protective and curative action, absorbed through the leaves, stems, and roots.
Used 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 Pseudopernospora humuli on hops, Phytophthora infestans on potatoes, Peronospora tabacina on tobacco, and Plasmopara viticola on vines. Soil applications of metalaxyl alone are used to control soil-borne pathogens causing root and lower stem rots on avocado and citrus; also recommended for primary systemic infections of P.humuli on hops and in tobacco seed beds. Seed treatments control systemic Peronosporaceae on maize, peas, sorghum and sunflowers, as well as damping-off (Pythium spp.) of various crops.
