Composés benzamidiques à activité fongicide et leur utilisation

Benzamidic compounds having fungicidal activity and relative use

Abstract

The present invention relates to benzamidic compounds having general formula (I): wherein: R x represents a halogen atom or a methyl group possibly substituted by fluorine atoms; R 1 , R 2 , R 3 , independently from each other, represent a C 1 - C 3 alkyl group; R 4 represents a hydrogen atom or a C 1 -C 3 alkyl group; R y represents a halogen atom, a C 1 -C 4 alkyl group, a C 1 -C 4 haloalkyl group, a C 1 -C 4 alcoxy group, a C 1 -C 4 haloalcoxy group; n represents an integer ranging of from 0 to 3. The present invention also relates to the use of the above benzamidic compounds for the control of fungi, bacteria and phytopathogenic viruses of agricultural crops.
Composés benzamidiques représentés par la formule générale (I) : dans laquelle R x représente un atome d'halogène ou un groupe méthyle éventuellement substitué par des atomes de fluor; R 1 , R 2 et R 3 , indépendamment les uns des autres représentent un groupe C 1 - C 3 alkyle; R 4 représente un atome d'hydrogène ou un groupe C 1 - C 3 alkyle; Ry représente un atome halogène, un gouape C 1 -C 4 alkyle, un groupe C 1 -C 4 haloalkyle, un groupe C 1 -C 4 alcoxy, un groupe C 1 -C 4 haloalcoxy; n représente un entier compris entre 0 et 3. Cette invention concerne également l'utilisation des composés benzamidiques susmentionnés dans la lutte contre les champignons, les bactéries et les virus phytopathogènes des cultures agricoles.
