The present invention relates to an insecticidal coating for a corn seed comprising one or more binders selected from the group consisting of polymers and copolymers of polyvinyl acetate, methyl cellulose, polyvinyl alcohol, vinylidene chloride, acrylic, cellulose, polyvinylpyrrolidone and polysaccharide and an insecticide and filler wherein the binder forms a matrix for the insecticide and filler resulting in a substantially non-phytotoxic seed coating; methods for producing said coating and the seed treated with the above described coating. Additionally, the invention concerns a method of controlling soil-borne insect pests, particularly from the order of Coleoptera or Lepidoptera, comprising a) applying to a corn seed an insecticidal coating as described above, and transforming the corn seed with one or more transgenes coding for one or more proteins that confer pesticidal resistance to the corn seed.
An insecticidal coating for a corn seed comprising:
An insecticidal coating for a corn seed comprising a binder in an amount from about 0.01 to about 15% of the weight of the seed wherein said binder is a vinyl acetate-ethylene copolymer or polymer or copolymer of vinylidene chloride, a filler in an amount from about 0.01 to about 50% of the weight of the seed wherein said filler is diatomaceous earth and amorphous silica, and an insecticidally effective amount of a compound effective against corn root worm or its larvae selected from compounds of the group consisting of the compounds of formula II, imidacloprid, tefluthrin, and combinations thereof, and in the range from about 0.005 to about 50% of the weight of the seed.
A method of preparing coated corn seeds comprising:
