Metalaxyl-M
other name: methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-D-alaninate
CAS No.: [70630-17-0 ]
Molecular Formula: C15H21NO4
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 left hand and right hand sometimes looks just same or they forgot mirror pictures. isomer are more complicated viewing from 3-D space or its structure.
Reports about metalaxyl M type is more stronger than Metalaxyl, you can think about a fact that right hand is more powderful comparing with left hand for most people.
Key Features and Benefits of using Metalaxyl and Metalaxyl M is reported as these:
- 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)
Biochemistry: Inhibits protein synthesis in fungi, by interference with the synthesis of ribosomal RNA.
APPLICATIONS
Biochemistry
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.
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-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.
