<p>A composition for controlling helminths in both domestic animals and productive animals, which contains as active component a synergistic active-substance combination. This active-substance combination comprises the individual compounds of the formula I < IMG > (I), wherein n is 0 or 1, and of the formula II < IMG > (II) wherein R1 is the group -NH-COOR-R3, in which R3 is an alkyl group having 1 to 9 carbon atoms, preferably methyl, or R1 is a thiazol-4-yl group, R2 is an alkyl group having 1 to 4 carbon atoms, preferably n-propyl, phenyl unsubstituted or substituted by halogen or alkyl, or it is a cycloalkyl group having 3 to 6 carbon atoms, and X is O, S, SO, CO, methylene, preferably S or SO, or an -NH-COO group, including the isomers embraced by the formula II, and also the acid addition salts of these compounds. The synergistic compositions are used for controlling nematodes, cestodes and particularly trematodes in animals. The active-substance combinations can be added to the feed or introduced into the drinking troughs, or can be administered in preparations made up with customary carriers. in the solid or liquid form, to the animals perorally, by injectlon or by the pour-on method.</p> |
