<p>The invention relates to novel 5-phenylcarbamoylthiobarbituric acid derivatives of the general formula <IMAGE> +TR <IMAGE> wherein R1 and R2 are each independently C1-C5alkyl or methoxy, R3 is unsubstituted phenyl, unsubstituted pyridyl, or phenyl which is substituted by 1 to 3 identical or different members selected from the group consisting of C1-C5alkyl, C1-C4cyanoalkyl, halogen, nitro and C1-C5haloalkyl containing 1 to 5 halogen atoms, or is pyridyl which is substituted by 1 to 3 identical or different members selected from the group consisting of C1-C5alkyl, halogen, nitro and C1-C5haloalkyl containing 1 to 5 halogen atoms and R4 and R5 are each independently hydrogen, halogen, C1-C5alkyl, C1-C2haloalkyl containing 1 to 3 halogen atoms, or are C1-C3-alkoxy or nitro, and to the tautomers and salts thereof, as anthelmintics. The compounds may be used by themselves or together with suitable carriers and further adjuvants for controlling helminths which are parasites of animals.</p> |
