Novel compounds are described which are substituted benzophenone hydrazones. They have pesticidal activity, especially against insects and acarids, and pesticidal compositions and methods are described. Methods of making the compounds, and novel intermediates, are also described.

Compositions and method of combatting pest employing substituted

Pesticide compounds

A new method of controlling pests harmful to domestic animals and certain novel pesticidal compositions are described. Compounds for use in the method have the formula ##STR1## in which n is 0 to 5, R is halo, alkyl, trihaloalkyl, cyano alkoxy or alkoxycarbonyl, R.sup.1 and R.sup.2 are each hydrogen, alkyl alkenyl, alkynyl, acyl, or hydrocarbyloxycarbonyl and R.sup.3 and R.sup.4 are each hydrogen or alkyl; or an acid addition. The method is of particular value for controlling ectoparasites which attack cattle and pigs. Certain of the compounds are novel.

Compounds, compositions and methods for controlling pests

1(2)-(N,N-disubstituted carbamoyl)-3,5-substituted-1,2,4-triazoles, with insecticidal and nematicidal properties, are described.

Triazole compounds

1(2)-(N,N-disubstituted carbamoyl)-3,5-substituted-1,2,4-triazoles, useful as insecticidal compounds, and their preparation, are described.
