Title:
SEED COATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/187994
Kind Code:
A1
Abstract:
This water-dispersible seed coating material is characterized by comprising titanium oxide, talc, polyvinyl alcohol, and an ethylene-vinyl acetate copolymer, and in that the seed coating material, which contains water, has a titanium oxide content of 10-40% by mass, a titanium oxide-to-talc weight ratio of 3:1 to 0.5:1, and a PVA-to-EVA weight ratio of 3:1 to 0.5:1. This reduces precipitation of titanium oxide during storage and results in excellent redispersibility. The seed coating material is less likely to cause seeds to attach to each other or to a processing tank during coating processing, and the color of coated seeds is good and not affected by the seed coat color. The coating layers do not peel away from the seeds, and there is no adverse effect on the germination performance.
