APPLICATIONS
BiochemistryMode of action is believed to be the same as for fenpiclonil. Inhibits MAP kinase, in osmotic signal transduction. Mode of actionNon-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. UsesAs 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.
ENVIRONMENTAL FATE
AnimalsRapidly 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. PlantsMetabolism 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/EnvironmentFormation 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).
