Microbicidal agents on the basis of biphenylbenzamide derivatives
View Patent ↗The present invention relates to novel microbicidal compositions based on biphenylbenzamide derivatives of the formula (I) in which R 1 , R 2 , R 3 and m are as defined in the disclosure, to novel biphenylbenzamides, to a plurality of processes for preparing these substances and their use for controlling pests, and to novel intermediates and processes for their preparation.
1. A biphenylbenzamide derivative of formula (Ia)
in which
R 1 represents methyl, trifluoromethyl, chlorine, bromine, or iodine,
R 2 represents hydrogen,
R 3 represents halogen, cyano, nitro, C 1 –C 6 -alkyl, C 1 –C 4 -alkoxy, C 1 –C 4 -alkylthio, C 1 –C 4 -alkylsulphonyl, C 2 –C 6 -alkenyl, or C 3 –C 6 -cycloalkyl; or represents C 1 –C 6 -haloalkyl, C 1 –C 6 -haloalkoxy, C 1 –C 6 -haloalkylthio, or C 1 –C 6 -haloalkylsulphonyl having in each case 1 to 13 halogen atoms, and
n represents 2, 3, 4, or 5, where the radicals R 3 may be identical or different.
2. A composition for controlling unwanted microorganisms comprising one or more biphenylbenzamide derivatives of formula (Ia) according to claim 1 and one or more extenders and/or surfactants.
3. A process for preparing a composition for controlling unwanted microorganisms comprising mixing one or more biphenyl-benzamide derivatives of formula (Ia) according to claim 1 with one or more extenders and/or surfactants.
