ENVIRONMENTAL FATE

Animals: In mammals, following oral administration, rapidly absorbed and also rapidly and almost completely eliminated in urine and faeces. Metabolism proceeds via hydrolysis of the ester bond, oxidation of the 2-(6)-methyl group and of the phenyl ring and N-dealkylation. Residues in tissues were generally low and there was no evidence for accumulation or retention of metalaxyl-M or its metabolites. Plants: Metabolised by more than 4 types of phase I reaction (oxidation of the phenyl ring, oxidation of the methyl group, cleavage of the methyl ester and N-dealkylation) to form eight metabolites; at phase II, most of the metabolites are sugar conjugated. Soil/Environment DT50 in soil 21 d (realistic range 5-30 d). Koc 45 ml/g (realistic range 30-300 ml/g). Stable to photolysis.

Usage: Reported by C. Nuninger et al. (Proc. Br. Crop Prot. Conf. - Pests Dis., 1996, 1, 41). Developed by Ciba-Geigy AG (now Syngenta AG) and introduced in the US in 1996. Manufacturers: Syngenta.

Application: 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. Systemic fungicide with protective and curative action, absorbed through the leaves, stems, and roots. Used 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.
