Metalaxyl, 甲霜灵 other name: methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-DL-alaninate

CAS No.: [ 57837-19-1 ]

Molecular Formula: C15H21NO4

Metalaxyl is used for control of phytophthora root rot of avocados, phytophthora root rot and trunk canker of macadamia nuts, phytophthora trunk rot of peaches, damping off of certain vegetable crops.

Key Features and Benefits of using Metalaxyl

  • Effectively controls phytophthora and pythium related diseases in a range of tree and vegetable crops.
  • Permits for use in raspberry and blueberry for phytophthora and herbs, roses, wildflowers for pythium and phytophthora root rot
  • Metalaxyl can be used as a resistance management tool when rotated with other mode of action fungicides like phospot (phosphorous acid)Metalaxyl, phytophthora root

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.

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.

Formulation types: DS; FS; GR; WP.
