Abstract

An insecticide comprises particles of a toxic substance, which is not repellant to insects and which is lethal to a number of different kinds of insects including Hymenoptera, coated with a protein or polysaccharide which is insoluble in water and in the alimentary tracts of Hymenoptera, but soluble in the alimentary tracts of leaf-eating or wood-eating insects. Specified toxic substances are 4, 41-dichlordiphenyl - b , b , b - trichlorethane and g -benzene hexachloride. Liquid toxic substances may be absorbed in an inert carrier. Suitable proteins are zein, or water-soluble proteins, such as casein, gelatin or a degraded gelatine such as a size which has been insolubilised by treatment with formaldehyde, with or without the addition of sulphuric acid and salt, benzoquinone or potassium dichromate, or with certain proteins such as casein by conversion to an insoluble salt. The polysaccharide may be a degraded form of cellulose produced by dissolving ordinary cellulose in one of the known agents, e.g. ammoniacal cupric chloride and bubbling oxygen through the liquid. The degraded cellulose can then be precipitated on the particles of toxic agent, for example by the addition of hydochloric acid. Protein coatings can also be applied in an essentially similar manner provided solutions thereof can be made in a liquid in which the toxic agent is insoluble. The protein may be rendered insoluble after the coating has been applied. The solvent is preferably removed by spray drying. The Provisional Specification describes also dinitro-o-cresol, dinitro-cyclohexyl-phenol, tetra-nitro-carbazoles and the hexa ethyl ester of tetraphosphoric acid as suitable toxic substances.
