ABSTRACT:
Fuzzy cotton seed is coated to produce a flowable product which is more easily transported and handled and also may be planted by the same planting equipment that is used to plant other seeds, such as corn and beans. The coating process includes first wetting the seed with a solution of a guar derivative such as hydroxypropyl guar. Then the wetted seed is mixed with an excess of a dry powdered guar product, the excess powder screened off, and the coated seed dried.
