Embodiment 1

[0165] Embodiment 1: the processing of soybean seed

[0166] Seed coating formulations were prepared according to Table 2. Soybean seeds were treated with a base of Acceleron® packs (Monsanto Company, containing metalaxyl, pyraclostrobin, imidacloprid, and flufenapyr), Color Coat Red, and water to achieve a concentration of 5.8 fl. oz / cwt. Accelron® package ratio.

[0167]

[0168] Dust Shedding Procedure : The dried treated soybean seeds are tumbled under vacuum in a closed system. A stream of air is maintained through the container, which is filtered through the screen. The amount of dust on the filter was weighed and the results are shown in Table 3 below.

Abstract

The present invention relates generally to an aqueous seed coating composition based on a specific polyvinyl alcohol copolymer resin as a binder plus a hydrophobic pesticide additive, and seeds coatedwith such coating composition, which coated seeds have a desirable combination of bulk low dusting, bulk seed flowability and good germination characteristics.

Description

[0001] field of invention [0002] The present invention generally relates to aqueous seed coating compositions based on specific polyvinyl alcohol copolymer resins as a base, and seeds coated with such coating compositions. The resulting coated seeds have a desirable combination of bulk low dusting, bulk seed flowability and good germination characteristics. [0003] In particular, polyvinyl alcohol copolymers are selected from (a) specific highly hydrolyzed copolymers of vinyl acetate with minor amounts of ethylene, and (b) vinyl acetate with minor amounts of unsaturated acid comonomer components Specific highly hydrolyzed copolymer. [0004] Seed coating compositions comprise such polyvinyl alcohol copolymers in an aqueous carrier medium together with hydrophobic "pesticide" additives and other optional additives. [0005] Background of the invention [0006] Seed treatment refers to the application of materials to seeds to improve handling characteristics, protect seeds p...
