The invention relates to a composition for the control of helminths in animals which contains a synergistic active ingredient combination which comprises the individual compounds of the formula I <IMAGE> (I) and of the formula II <IMAGE> (II) wherein R1 is the -NH-COO-R3 group, in which R3 is an alkyl radical of 1 to 4 carbon atoms, preferably methyl, R2 is an alkyl radical of 1 to 4 carbon atoms, preferably n-propyl, phenyl or phenyl substituted by halogen or alkyl, preferably unsubstituted phenyl, and X is -O-, -S- or -SO-, including the acid addition salts of the compounds falling under the formula II. These synergistic compositions are used for controlling helminths, especially nematodes, in animals. The active ingredient combinations can be administered to the animals both as additive to ready prepared solid and liquid feeds and in the form of compositions, together with conventional carriers in solid or liquid form, orally, by injection, or by the pour-on method. |
