Metalaxyl-M 92% TC
Metalaxyl-M is the biologically active enantiomer (Renantiomer) of the racemic compound Metalaxyl (see also commodity of Metalaxyl). Normal people can hardly find any difference between Metalaxyl and Metalaxyl M. this is like the left hand and right hand sometimes look just the same or they forgot mirror pictures. isomer is more complicated to view from 3-D space or its structure.
- Common name: Metalaxyl-M
- IUPAC name: methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-D-alaninate
- CAS No.: 70630-17-0
- Molecular formula: C15H21NO4
- Molecular weight: 279.33
- State: Solid
- Packing: 25kg (providing additional packing as required)
- Mode of action: Inhibits protein synthesis in fungi, by interference with the synthesis of ribosomal RNA. The (R)- (metalaxyl-M) and (S)- isomers have the same mode of action, but differ considerably in effectiveness.
- Application: 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-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 100-140 g 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, Phytophthora nicotianae on tobacco, Phytophthora spp. on peppers, and Pythium spp. on many different crops, including ornamentals, at 250-1000 g/ha. Seed treatments control systemic Peronosporaceae on maize, peas, sorghum, and sunflowers, at 35 – 300 g/100 kg seed, as well as damping-off (Pythium spp.) of various crops, at 8.25-17.5 g/100 kg seed.
