METALAXYL-M
Common name: Metalaxyl-M
Chemical name: methyl N-(methoxyacetyl)-N-(2,6-xylyl)-D-alaninate
Molecular formula: C15H21NO4
Molecular weight: 279.3
CAS No.：70630-17-0
Structural formula:
Physical Chemistry: Form light yellow to light brown thick liquid, M.p.38.7°C, B.p.270°C, V.p.3.3mPa(25°C) S.g/density:1.125(20°C) Solubility In water 26g/l(25°C). In n-hexane 59g/l; miscible with acetone, ethyl acetate, methanol, dichloromethane, oluene, n-octanol.
Use: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 metalxyl-M 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,downy mildews of vegetables,and Bremia lactucae on lettuce,at 100-140g metalaxyl-M/ha.Soil applications of metalaxyl-M alone are used to control soil-borne pathogens causing root and lower stem rots on avocado and citrus,Phythophthora nicotianae on tobacco, Phytophthora spp.on peppers,and pythium spp.on many different crops, including ornamentals,at 250-1000g/ha.Seed treatments control spp.on many different crops,including ornamentals,at 250-1000g/ha.Seed treatments control systemic peronosporaceae on maize,peas,sorghum and sunflowers,at 35-300g/100kg seed,as well as damping-off(Pythium spp.) of various crops,at 8.25-17.5g/100kg seed.
Mammalian toxicology: Oral Acute oral LD50 for rats 667mg/kg. Skin and eye Acute percutaneous LD50 for rats>2000mg/kg.Not a skin irritant(rabbits);risk of serious damage to eyes(rabbits).
