US 11,284,558 B2 · Biopolymer-based seed coatings compositions and methods for use

Abstract

A seed or seedling is coated with a cross-linked biopolymer and, optionally, a second binder selected from underivatized guar, cationic hydroxypropyl guar, polyacrylamide, poly(methacrylic acid), poly(acrylic acid), polyacrylate, poly(ethylene glycol), polyethyleneoxide, polyamide, hydroxypropyl guar, carboxymethyl guar, carboxymethylhydroxypropyl guar, underivatized starch, cationic starch, corn starch, wheat starch, rice starch, potato starch, tapioca, waxy maize, sorghum, waxy sarghum, sago, dextrin, chitin, chitosan, xanthan gum, carageenan gum, gum karaya, gum arabic, pectin, cellulose, hydroxycellulose, hydroxyalkyl cellulose, hydroxyethyl cellulose, carboxymethylhydroxyethyl cellulose, or hydroxypropyl cellulose. The seed coating composition is characterized by a dust value, as measured using a Heubach dustmeter device, which is lower by at least 30% as compared to an analogous composition that does not contain the crosslinked biopolymer.

Dependent claims

A coated seed composition comprising:

at least one seed;
and
at least one layer coating all or part of the seed, the layer comprising:
a crosslinked biopolymer having an average particle size of less than 400 nm, wherein the crosslinked biopolymer is less than 1% wt of the at least one seed;
and
optionally, a second binder comprising guar, derivatized guar, starch, derivatized starch, or a combination of any of the foregoing,
wherein the composition is characterized by a dust value, as measured using a Heubach dustmeter device, which is lower by at least 30% as compared to an untreated seed that does not contain the crosslinked biopolymer or the at least one layer.
