Seed coatings, coating compositions and methods for use

A method of applying a dry seed coating composition comprising:

• introducing a seed into a soil;
• and
• in-situ coating the seed with the dry seed coating composition comprising at least 60 wt %, based on the weight of the composition, of guar or derivatized guar,
• where the derivatized guar is one or more selected from the group consisting of carboxymethyl guar, hydroxyethyl guar, hydroxypropyl guar, carboxymethylhydroxypropyl guar, cationic hydroxylpropyl guar, hydrophobically modified guar, hydrophobically modified carboxymethyl guar, hydrophobically modified hydroxyethyl guar, hydrophobically modified hydroxypropyl guar, cationic hydrophobically modified hydroxypropyl guar, hydrophobically modified carboxymethylhydroxypropyl guar, and hydrophobically modified cationic guar,
• where the cationic hydroxylpropyl guar or the cationic hydrophobically modified hydroxypropyl guar include trimethylamino (2-hydroxyl) propyl, with chloride as a counter ion, and
• wherein the seed coating composition promotes seedling establishment through wetting adjacent areas of soil around the seed compared to when the seed is not coated with the dry seed coating composition.

• where the cationic hydroxylpropyl guar or the cationic hydrophobically modified hydroxypropyl guar include trimethylamino (2-hydroxyl) propyl, with chloride as a counter ion,
• where the seed coating composition comprises an active ingredient that is one or more selected from the group consisting of an herbicide, a plant growth regulator, a crop desiccant, a fungicide, a bacteriocide, a bacteriostat, an insecticide, a miticide, an insect repellant, an adjuvant, a surfactant, and a fertilizer,
• where the miticide is one or more selected from the group consisting of a propynyl sulfite miticide, a triazapentadiene miticide, a chlorinated aromatic miticide, and a dinitrophenol miticide, and
• wherein the seed coating composition promotes seedling establishment and protects against water loss compared to when the seed is not coated with the dry seed coating composition.
