High Quality 35% WP 25% EC Fungicide Metalaxyl

Active ingredient

Metalaxyl

Chemical name

methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-DL-alaninate

Classification

Fungicide / Agrochemical

Formulation

98% Tech, 35% WP, 25% WP, 5% G, 25% EC, 24% SL

Biochemistry

Inhibits protein synthesis in fungi, by interference with the synthesis of ribosomal RNA.

Mode of action

Systemic fungicide with protective and curative action, absorbed through the leaves, stems, and roots.

Usage

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.
