    • The invention comprises s-triazine derivatives of the formula:- in which D1 and D2 are methyl or ethyl radicals; D3 is a hydrogen atom; D4, D5 and D6 which can be the same or different are each a hydrogen atom or a methyl, ethyl, propyl or butyl radical, or D5 and D6 together with their adjacent nitrogen atom constitute a piperidino ring; D7 is a methyl, ethyl, propyl, or butyl radical, and X is an oxygen or sulphur atom; and acid addition salts thereof, e.g. hydrochlorides, oxalates, p-toluene sulphonates, methane sulphonates and isethionates. They may be obtained by reacting a compound of the formula: with a haloalkyl-s-triazine of the formula:- wherein D1 to D7 and X are as defined above, M is an atom of an alkali metal, e.g. sodium, or is an ammonium radical, and Y is a halogen atom e.g. bromine. The process is preferably effected at between 20 DEG and 150 DEG C. and the reactants may be used in solution or dispersion in a suitable solvent or diluent e.g. water, methanol, or ethanol. The products have pesticidal properties (see Group VI). Haloalkyl-s-triazines of the above formula may be obtained by reacting a compound Y.CH(D7).COOD8 with a triguanide of the formula:- wherein D3 to D7 and Y are as defined above and D8 is a lower alkyl radical, e.g. methyl or ethyl.ALSO:A pesticidal composition comprises a suitable diluent or carrier and as active ingredient a compound of the formula wherein D1 and D2 are methyl or ethyl radicals; D3 is a hydrogen atom; D4, D5 and D6 which can be the same or different are cach a hydrogen atom or a methyl, ethyl, propyl or butyl radical, or D5 and D6 together with their adjacent nitrogen atom constitute a piperidino ring; D7 X is an oxygen or sulphur atom or an acid addition salt thereof, e.g. a hydrochloride, oxalate, p-toluene sulphonate, methane sulphonate, or isethionate (see Group IV (b)). Specified diluents or carriers are water, organic solvents e.g. methanol, tetrahydrofurfuryl alcohol, diacetone alcohol, and beta-ethoxyethanol; fuller's earth, tale, kaolin, kieselguhr and bentonite. Wetting or dispersing agents may also be present. The active ingredient or the compositions containing it may be used for the treatment of seed before sowing to provide subsequent protection against aphids for the plants grown from the seed.
