FENPICLONIL

Описание

Fenpiclonil is the first phenylpyrrole fungicide developed by Ciba Geigy (now belonging to the portfolio of Syngenta Crop Protection AG) for seed treatment. Different formulation types have been used for its commercialization either in solo (trade name “Beret”) or in mixture with other fungicides, as for instance, imazalil (“Beret Special”) or carboxin + imazalil (“Beret Universal”).

Использование

Fenpiclonil is a systemic and contact fungicide that provides protective control of seed-borne pathogens of cereals such as snow mould and bunt caused by Fusarium spp., Tilletia caries, Septoria nodorum, etc. It also controls leaf spot, brown foot rot and ear blight in non-cereal crops.

Определение

ChEBI: A member of the class of pyrroles carrying cyano and 2,3-dichlorophenyl substituents at positions 3 and 4 respectively. A fungicide used mainly to control seed-borne pathogens in cereal crops.

Общее описание

Fenpiclonil is a phenylpyrrole fungicide and a structural analogue of the antibiotic pyrrolnitrin found to be toxic to representatives of Ascomycetes, Basidiomycetes, and Deuteromycetes.

Метаболический путь

Limited data are available in the open literature. Information presented in this summary was abstracted from the data evaluation published by the Pesticide Safety Directorate (PSD, 1993). Fenpiclonil is stable to hydrolytic and soil degradation. Photolytic degradation is rapid. Hydroxylation and oxidation of the pyrrole ring are the primary metabolic reactions in plants and animals (Scheme 1).
