    • The invention relates to new sulphonyl compounds of the general formula wherein X is a halogen atom, a phenoxy group, or an alkyl group or alkoxy group having 1-4 carbon atoms and substituted, if desired, with halogen; R1 is a cyano group, and R2 is an amino group which, if desired, may be substituted with halogen, with one or two alkenyl groups or alkynyl groups having 2-6 carbon atoms or with one or two alkyl groups having 1-6 carbon atoms, which alkyl groups, together with the nitrogen atom to which they are bound, may form a saturated heterocyclic ring, which ring may also contain a second hetero atom selected from the group consisting of nitrogen, oxygen and sulphur, or which alkyl groups may be substituted with an alkoxy group, having 1-4 carbon atoms, or with a dialkylamino group having 2-6 carbon atoms the alkyl groups of which, together with the nitrogen atom to which they are bound, may form a saturated heterocyclic ring; or wherein R1 and R2 together form a S,S-dialkylsulphoximido group the alkyl groups of which comprise 1-4 carbon atoms, or a 1-amino-2-azavinylene group, of which the amino group is substituted, if desired, with a cycloalkylcarbamoyl group having 4-8 carbon atoms, an alkylcarbamoyl group having 2-5 carbon atoms, a dialkylamino group the alkyl group of which comprise 1-4 carbon atoms, or an alkyl group having 1-4 carbon atoms which alkyl group may be substituted with a hydroxy group or one or more halogen atoms; or wherein R1 and R2 together form a 1-imino-2-azaethylene group of which the ring nitrogen is substituted with an alkyl group or alkenyl group having 1-4 carbon atoms, and of which the imino group may be substituted with a substituted or non-substituted phenylcarbamoyl group, having aphicidal activity. After having been processed to compositions, the compounds may be used for the control of aphids in agriculture, horticulture and forestry in a dosage from 20 to 5,000 g of active substance per hectare.
