Formula of fungicide metalaxyl is C15H21NO4 and chemical name is 2-[(2, 6-dimethylphenyl)-(2-methoxy-1-oxoethyl) amino]propanoic acid methyl ester. Pure product is white powder. For solubility, it is 8.4g/L in water under 22℃, 450g/L in acetone, 400g/L in ethanol, 340g/L in toluene, 11g/L in n-hexane and 68g/L in octanol. As systemic chemical, this product has therapeutic and protective effects. For mechanism, it is absorbed by roots, stems and leaves of plants and transported to various organs with water, thus inhibiting bacteria ribosomal RNA I synthesis and killing the fungi.

This product has low toxicity. To be more specific, acute oral LD50 of original drug for rats is 669 mg/kg and acute dermal LD50 is bigger than 3100 ml/kg. With mild irritation to eyes and skin, this product has low toxicity to fish and TLM for trout is 100 mg/kg. For long time use of this product, fungi can develop drug-resistance so it can be used together with other chemical or rotation can be adopted. In addition, this product should be stored in ventilated and dry conditions with temperature lower than 35℃.

As a Chinese fungicide metalaxyl manufacturer and supplier, Eastchem offers fungicide mancozeb, fungicide propiconazole, and fungicide tebuconazole as well as a variety of herbicides and insecticides such as herbicide glyphosate, insecticide emamectin benzoate and insecticide chlorpyrifos-ethyl.
