Development of a new fungicide, benthiavalicarb-isopropy

Abstract

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. © Pesticide Science Society of Japan.
