Benthiavalicarb-isopropyl 177406-68-7 95% TC, 98% TC, 15% WDG



Introduction: Benthiavalicarb-isopropyl is a novel fungicide belonged to the carboxylic acid amides (CAA) group. This compound is a highly selective fungicide that has superb preventive and curative effects on late blight and downy mildew caused by plant pathogens that belong to Oomycetes. Benthiavalicarb-isopropyl strongly inhibits mycelia growth, zoosporangia germination and cystospore germination, and also inhibits the sporulation of Phytophthora infestans at a very low concentration. The fungicidal and disease-controlling activities of benthiavalicarb-isopropyl are characterized by its excellent preventive, curative, translaminar, systemic movement, residual activities, its inhibitory activity toward lesion development and its rain fastness. These results suggest that the biological properties of benthiavalicarb-isopropyl contribute to its excellent ability to control several diseases in the field.

Animals In rats, following oral administration, excretion was predominantly via the bile and virtually completed by 168 hours. The metabolism was complex; the predominant routes were glutathione conjugation, or hydroxylation on the benzene or the valyl moieties. Plants In plants, metabolism proceeds slowly. The major metabolites are similar to those in animals. Soil/Environment In the laboratory, benthiavalicarb-isopropyl was readily degraded in soil; DT50 11-19 d (20°C, aerobic), 40 d (20°C, anaerobic). Koc 121-258. 

Usage: Benthiavalicarb-isopropyl was developed by Kumiai Chemical and Ihara Chemical. It is new fungicide active against Oomycetes fungal plant pathogens, control of diseases such as Blight, Downy mildew, in vegetables, potatoes, vines, tomatoes, grapes, etc.
Application: Biochemistry Proposed inhibitor of cell wall synthesis. Mode of action Protective and curative action with residual effects, inhibits phospholipid biosynthesis. Uses For use against downy mildew and late blight on vegetables, potatoes and grapes, at 25-75 g/ha.
