 FUNGICIDE
>> Metalaxyl
|
Common name: Metalaxyl
Chemical name: methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate
Structure formula:
Molecular formula: C15H21NO4
CAS RN: 57837-19-1
Use: To control diseases caused by air-and soil-borne Peronosporales on a wide range of temperate, subtropical and tropical crops. Foliar sprays with mixture of metalaxyl
and protectant fungicides are recommended to control air-borne diseases caused by
Pseudoperonospora humuli on hops,
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.
