Novel imidazole compounds, pesticidal compositions and methods of using them, and their preparation are described. The compounds have the formula ##STR1## in which X is oxygen or sulphur, R.sup.3 is hydrogen, alkyl, alkenyl or optionally substituted alkylthio, alkenylthio, aralkylthio, alkoxyalkyl or alkylthioalkyl, R.sup.4 is alkyl or cycloalkyl, and R.sup.1 and R.sup.2 are each lower alkyl or alkenyl, R.sup.1 is lower alkyl and R.sup.2 is alkoxyalkyl or haloalkyl, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are attached, form an optionally substituted heterocyclic ring; and salts thereof. Novel compounds are of particular value against insects e.g. aphids, and against other pests, e.g. acarids.

1-Morpholinocarbonyl imidazoles

New imidazole compounds, pesticidal compositions and methods of using them, and their preparation are described. The compounds have the formula ##STR1## in which X is oxygen or sulphur, R.sup.3 is hydrogen, alkyl or alkenyl, R.sup.4 is alkyl or cycloalkyl, and R.sup.1 and R.sup.2 are each lower alkyl or alkenyl, R.sup.1 is lower alkyl and R.sup.2 is alkoxyalkyl or haloalkyl, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are attached, from a heterocyclic ring. Novel compounds are of particular value against insects e.g. aphids, and against other pests, e.g. acarids.

1-Carbonamido imidazoles

Thio derivatives of imidazol-1-yl carboxamides

Insecticidal composition comprising a compound of the formula ##SPC1## In which X is selected from the group consisting of oxygen and sulphur, R.sup.3 is selected from the group consisting of hydrogen and alkyl of 1 to 4 carbon atoms, R.sup.4 is selected from the group consisting of alkyl of 1 to 10 carbon atoms and cycloalkyl of 3 to 10 carbon atoms, form a morpholino group optionally containing 1 to 4 methyl substituents attached to carbon atoms of the ring, together with a suitable carrier. The insecticidal compositions are of particular vaule against insects, e.g., aphids, and against other pests, e.g., acarids.
