CA 2702786

The present invention relates to novel imidazole derivatives of formula (I) as active ingredients which have microbiocidal activity, in particular fungicidal activity: wherein R is halogen, C1C4a1ky1 or Cl-C4haloalkyl; R is an optionally substituted aryl or heteroaryl; R3 is halogen; R4 is hydrogen, halogen, Cl-C4alky1,6C1-C4haloalkyl, hydroxyl, Cl-C4alkoxy, OR , Cl-C4haloalkoxy or cyano; R is halogen; R is hydrogen, C3-C7 cycloalkyl, C3-Cl0 alkylcycloalkyl, Cl-C6 haloalkyl, C2-C6 alkenyl, C2-C6 haloalkenyl, C3-C7 cycloalkenyl, C2-C6 alkynyl, C2-C6 haloalkynyl or C2-C6 alkyloxyalkyl; X is N or C(R); and R is hydrogen, halogen, Cl-C4alkyl, Cl-C4haloalkyl, Cl-C4aIkoxy, Cl-C4haIoaIkoxy or cyano; or an agrochemically usable salt form thereof; provided that when X is C(R), R cannot be an optionally substituted aryl.

Cette invention concerne des nouveaux dérivés d'imidazole représentés par la formule (I) en tant que principes actifs présentant une activité microbicide, en particulier, une activité fongicique: dans cette formule, R1 représente halogène, alkyle C1-C4 ou haloalkyle C1-C4; R2 représente un aryle ou un hétéroaryle éventuellement substitué; R3 représente halogène; R4 représente hydrogène, halogène, alkyle C1-C4, haloalkyle C1-C4, hydroxyle, alkoxy C1-C4, OR6, haloalkoxy C1-C4 ou cyano; R5 représente halogène; R6 représente hydrogène, cycloalkyle C3-C7, alkylcycloalkyle C3-C10, haloalkyle C1-C6, alcényle C2-C6, haloalcényle C2-C6, cycloalcényle C3-C7, alcynyle C2-C6, haloalcynyle C2-C6 ou alkyloxyalkyle C2-C6; X représente N ou C(R); et R représente hydrogène, halogène, alkyle C1-C4, haloalkyle C1-C4, alkoxy C1-C4, haloalkoxy C1-C4 or cyano; ou une forme saline utilisable pour des applications agrochimiques; pour autant que lorsque X est C(R), R2 ne peut représenter un aryle éventuellement substitué.
