Abstract

The invention comprises alkyl alkylthiophosphonates of the general formula <FORM:0989014/C2/1> in which R is a normal C3 or C4 alkyl group and R1 is a methyl or ethyl group. They may be obtained by treating an alkyl alkylthiophosphonyl halide of the general formula <FORM:0989014/C2/2> in which R and R1 are as above defined and Z is a halogen having an atomic number of at least 17 with 4-nitro-phenol in the presence of an acid acceptor, e.g. an alkali metal carbonate or a tertiary amine. An inert organic solvent e.g. acetone, butanone, dioxane, benzene, toluene, or xylene may be present. Preferred reaction temperatures are from 10 DEG C. to 120 DEG C. and the product may be purified by selective solvent extraction or by absorptive agents such as activated carbon or clays. The products have insecticidal properties (see Division A5).ALSO:An insecticidal composition comprises an alkylthiophosphonate of the general formula <FORM:0989014/A5-A6/1> wherein R is a normal C3 or C4 alkyl group and R1 is a methyl or ethyl group (see Division C2) and a carrier and/or water-soluble surfactant. The active ingredient is both a systemic and contact insecticide and the composition may be in the form of a solution, suspension or emulsion in an organic liquid or may be in the form of pellets, granules, powder or dust or in the form of a mixture, e.g. with a fluorochloroalkane, which is suitable as an aerosol. An adhesive, spreading agent, or humectant may also be present. Specified organic liquids are isopropyl ether, acetone, methyl ethyl ketone, dioxane, cyclohexanone, carbon tetrachloride, ethylene dichloride, tetrachloroethane, hexane, heptane, low molecular weight aliphatic hydrocarbons, hydrogenated naphthalenes, solvent naphtha, benzene, toluene, xylene, petroleum fractions (especially kerosene), and mineral oils having an unsulphonatable residue above 80%. The surfactant may be an anionic, cationic or non-ionic surface-active agent, an alkali metal alkylaryl sulphonate, a polyoxyethylene ether of an alkyl phenol or of a mono-higher fatty acid ester of a hexitan (e.g. sorbitan) being preferred. Specified solid carriers include the conventional carriers, volcanic ash, sulphur, powdered cork, powdered wood and powdered walnut shells. The active ingredient may also be dispersed in a semi-solid extending agent, e.g. petrolatum or soap, e.g. sodium stearate, oleate or palmitate. Other pesticides, e.g. nematocides, bactericides or herbicides may also be present.
