Abstract
The invention provides a method of preparing coated seeds, which comprises slurrying seeds with an inoculant composition containing a carrier medium, at least one species of microorganism having a beneficial effect on plants which grow from the seeds and an adhesive polymer, slurrying being effected in the presence of an aqueous suspension of an adhesive polymer; and air drying the resulting product at a temperature not greater than 30.degree. C.
Claims11
A method of preparing coated seeds, which comprises slurrying together (1) seeds, (2) an inoculant composition containing a carrier medium, at least one species of microorganism having a beneficial effect on plants which grow from the seeds, and a first adhesive polymer, and (3) an aqueous suspension of a second adhesive polymer selected from the group consisting of vinyl pyrrolidone/vinyl acetate copolymers, poly(methyl vinyl ether) maleic anhydride copolymers, free acids of the copolymer of methyl vinyl ether and maleic anhydride, vinyl pyrrolidone/styrene copolymers, partially hydrolyzed polyvinyl alcohols, vinyl acetate/butyl acrylate copolymers, vinyl acetate homopolymers, acrylic copolymers, styrene/acrylic ester copolymers, vinyl acetate/ethylene copolymers and polyvinyl acetate, component (3) being added separately before or during slurrying;
- and air drying the resulting product at a temperature not greater than 30.degree. C.
