Cyprodinil 嘧菌环胺  

Introduction: Cyprodinil is a new fungicide for the control of a broad spectrum of plant diseases. Control of major cereal diseases and of Botrytis cinerea ssp. on grapes and vegetables are the major strengths of cyprodinil. The careful analysis of physico-chemical properties of certain sulfonylureas and the consistent testing of all compounds as fungicides, herbicides and insecticides led to the discovery of the class of compounds and led to cyprodinil. Aspects of chemistry, structure activity considerations, ecological and safety assessments are presented to demonstrate the unique properties of cyprodinil which make it a versatile new tool for the management of plant diseases.

ENVIRONMENTAL FATE

Animals After oral administration, cyprodinil is rapidly absorbed and almost completely eliminated with urine and faeces. Metabolism proceeds by 4-hydroxylation of the phenyl and 5-hydroxylation of the pyrimidine rings, followed by mono- or di-sulfation. Residues in tissues were generally low and there was no evidence for accumulation or retention of cyprodinil or its metabolites. Plants Metabolism proceeded mainly via hydroxylation of the 6-methyl group of the pyrimidine ring, as well as hydroxylation of the phenyl and pyrimidine rings, followed by sugar conjugation. Soil/Environment In soil, the compound dissipated with DT5020-60 d at normal soil humidities and soil temperatures, whereby formation of bound residues represents the major route for dissipation. In leaching and adsorption/desorption experiments, the compound proved to be immobile in soil. Photolytic DT50 in water 13.5 d.   

Usage: Cyprodinil was introduced by Ciba-Geigy AG (now Syngenta AG). It is a broad spectrum foliar fungicide used to control a range of pathogens mainly on fruit.

Application: Biochemistry Proposed inhibitor of the biosynthesis of methionine and the secretion of fungal hydrolytic enzymes. There is no cross resistance to benzimidazoles, carbamates, dicarboximides, imidazoles, morpholines, quinolines, strobilurins or triazoles. Mode of action Systemic product, with uptake into plants after foliar application and transport throughout the tissue and acropetally in the xylem. Inhibits penetration and mycelial growth both inside and on the leaf surface. Uses As a foliar fungicide for use in cereals, grapes, pome fruit, stone fruit, strawberries, vegetables, field crops and ornamentals; and as a seed dressing on barley. Controls a wide range of pathogens, such as Tapesia yallundae and T. acuformis, Erysiphe spp., Pyrenophora teres, Rhynchosporium secalis, Botrytis spp., Alternaria spp., Venturia spp. and Monilinia spp., at 150-750 g/ha.
