<p>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, ii desired, with halogen: R1 is a cyano group, and R2 is an amino group which, if desired, may be substitu ted 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 heterocymay 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. Especially in the form of compositions including suitable diluents or carriers, 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.</p> |
