Rodenticidal compositions containing as the active ingredient novel 1-(3-pyridylmethyl)-3-(4'-substituted-phenyl or -naphthyl)ureas and their acid addition salts. The 4'-substituent may be nitro, cyano, trifluoromethyl, butyryl, thiocyano, alkylthio, phenylsulfonyl or diethylsulfonamide.

3-Pyridylmethyl aryl urea rodenticides compositions

Novel 1-(3-pyridylmethyl)-3-(4'-substituted-phenyl or -naphthyl)-ureas and their acid addition salts. The 4'-substituent may be -NO.sub.2, -CN, -CF.sub.3, -C(O)R.sub.1, -SCN, SR.sub.2, -SO.sub.2 C.sub.6 H.sub.5 or -SO.sub.2 NR.sub.3 R.sub.4. These compounds are biologically active, and many are active rodenticides.

3-Pyridylmethyl aryl urea rodenticides

Novel 1-(3-pyridylmethyl)-3-(4'-substituted-phenyl or -naphthyl)-ureas and their acid addition salts. The 4'-substituent may be --NO.sub.2, --CN, --CF.sub.3, --C(O)R.sub.1, --SCN, SR.sub.2, --SO.sub.2 C.sub.6 H.sub.5 or --SO.sub.2 NR.sub.3 R.sub.4. These compounds are biologically active, and many are active rodenticides.

Certain 3-pyridylmethyl N-(4'-substituted-phenyl)carbamates are useful as rodenticides, e.g., in baits or tracking powders. The 4'-substituent may be --NO.sub.2, --CN, --CF.sub.3, --SO.sub.2 NH.sub.2, --SR, --SOR or --SO.sub.2 R where R is lower alkyl. Their salts can also be made and applied as rodenticides.
