Fludioxonil 131341-86-1 95%TC SC WDG WP FS



Introduction: Fludioxonil is a synthetic phenylpyrrole-group substance. It is a kind of broad-spectrum, non-systemic fungicide, being used against Fusarium, Rhizoctonia, Alternaria and Botrytis cinerea. For dealing with the fungal diseases, it is usually applied in seed treatment as well as post-harvest treatment of fruits. Fludioxonil is effective in the treatment of many major seed diseases such as seedling blight, stem-base Browning, snow mould and common blunt. For post-harvest treatment, it can deal with Grey mould, storage rot, powdery mildew and black spot. It exerts its effect through interfering with the transport-associated phosphorylation of glucose as well as inhibiting glycerol synthesis, further inhibiting the mycelial growth. When used in combination with thiamethoxam and metalaxyl-M, fludioxonil can also be used for the treatment of pests such as peach-potato aphid, flea beetle and cabbage stem flea beetle.

Animals Rapidly absorbed from the gastrointestinal tract into the general circulation and rapidly and almost completely excreted, via the faeces. The dominant metabolic pathway is oxidation of the pyrrole ring at the 2-position. A minor pathway is hydroxylation of the phenyl ring. All metabolites are excreted as conjugates, mainly as glucuronides. Plants Metabolism proceeds via the oxidation of the pyrrole ring, opening of the pyrrole ring and pyrrolidine carboxylic acid metabolite. In general, the compound is extensively metabolised to more than 10-15 minor metabolites. Soil/Environment Formation of bound residues is the major route for dissipation in soil; DT50 (lab.) 140-350 d, (field) 10-25 d. In leaching and adsorption/desorption experiments, the compound proved to be immobile in soil. Photolytic DT50 in water 9-10 d (natural sunlight).                

Usage: Fludioxonil is a non-systemic fungicide, introduced in 1993 by Ciba-Geigy (now Syngenta). It is used for the treatment crops (particularly cereals, fruits and vegetables, and oramental plants; often in combination with another fungicide such as cyprodinil).

Application: Biochemistry Mode of action is believed to be the same as for fenpiclonil. Inhibits MAP kinase, in osmotic signal transduction. Mode of action Non-systemic product with long residual activity. Uptake into the plant tissues and curative properties are generally limited. Inhibits mainly the germination of conidia and, to a lesser extent, the germ tube and mycelial growth. Uses As a seed treatment, for control of Fusarium spp., Microdochium, Rhizoctonia, Tilletia, Pyrenophora and Septoria in both cereal and non-cereal crops, at 2.5-10 g/100 kg. As a foliar fungicide, for control of Botrytis, Monilinia, Sclerotinia, and Alternaria in grapes, stone fruit, berry crops, vegetables, and ornamentals, at 250-500 g/ha; also on turf, against Fusarium, Helminthosporium, Rhizoctonia, Sclerotinia and Typhula, at 400-800 g/ha. Also as a post-harvest treatment on stonefruit at 30-60 g/hl against Botrytis, Monilinia and Penicillium.
