Abstract:
1. A method of improving the germination rate of plant seeds which are treated with a phytotoxic agent, the method comprising: forming a polymer coating on the plant seed before treating the seed with the phytotoxic agent, wherein the coating comprises the polymer in an amount of at least about 50% by weight and where the polymer is selected from the group consisting of maltodextrin, methylcellulose, ethylcellulose, hydroxypropylcellulose, hydroxypropyl/methylcellulose, vinyl acetate - ethylene polymers, ethylene-vinyl chloride polymers, vinyl acetate polymers, vinyl-acrylic polymers, starch-based polymers, SB-2000, polyvinyl acetate -vinyl chloride polymers, vinyl chloride/ vinyl acetate/ ethylene copolymers, styrene-acrylate copolymers, vinylacetate polymers, vinylbutyrate polymers, styrene-vinylbutyrate copolymers, acrylate polymers, styrene-butadiene copolymers, vinylacetate-vinylbutyrate copolymers, and vinylacetate-vinylversatate copolymers, and where the coating is free of the phytotoxic agent and is a uniform coating having a thickness of from 1 to 500 microns and having between 0% and 20% unfused particles of the polymer in the coating; and treating the coated plant seed with the phytotoxic agent.
