The present invention relates to the use of compounds of formula (I) wherein A is an unsubstituted or mono- to tetrasubstituted, aromatic or non-aromatic, monocyclic or bicyclic heterocyclic radical, where one to two of the substituents of A can be selected from the group consisting of halo-C1- C3alkyl, cyclopropyl, halocyclopropyl, C2-C3alkenyl, C2-C3alkynyl, halo-C2- C3alkenyl, halo-C2-C3alkynyl, halo-C1-C3alkoxy, C1-C3alkylthio, halo-C1- C3alkylthio, allyloxy, propargyloxy, allylthio, propargylthio, haloallyloxy, haloallylthio, cyano and nitro, and one to four of the substituents of A can be selected from the group consisting of C1-C3alkyl, C1-C3alkoxy and halogen; R is hydrogen, C1-C6alkyl, phenyl-C1-C4alkyl, C3-C6cycloalkyl, C2-C6alkenyl or C2-C6alkynyl; and X is N-NO2 or N-CN, in the free form or in salt form or, if appropriate, tautomers thereof, in the free form or in salt form, for controlling fish parasites, in particular sea lice.
L'invention concerne l'utilisation de composés de la formule (I). Dans cette formule, A est un radical non substitué ou portant d'un à quatre substituants aromatiques ou non aromatiques, mono- ou bi-hétérocycliques, un à deux substituants de A pouvant être choisis parmi halo-C¿1?-C¿3? alkyle, cyclopropyle, halocyclopropyle, C¿2?-C¿3? alcényle, C¿2?-C¿3? alcynyle, halo-C¿2?-C¿3? alcényle, halo-C¿2?-C¿3? alcynyle, halo-C¿1?-C¿3? alcoxy, C¿1?-C¿3? alkylthio, halo-C¿1?-C¿3? alkylthio, allyloxy, propargyloxy, allylthio, propargylthio, haloallyloxy, haloallylthio, cyano et nitro, et un à quatre substituants de A peuvent être choisis dans le groupe C¿1?-C¿3? alkyle, C¿1?-C¿3? alcoxy et halogène; R est un hydrogène, C¿1?-C¿6? alkyle, phényl-C¿1?-C¿4? alkyle, C¿3?-C¿6? cycloalkyle, C¿2?-C¿6? alcényle ou C¿2?-C¿6? alcynyle; et X est N-NO¿2? ou N-CN. Ces composés peuvent être utilisés sous la forme libre, comme sel ou, lorsque cela est approprié, sous la forme de tautomères (forme libre ou sel), pour combattre les parasites infestant les poissons et, en particulier, les poux des poissons.
