## Abstract

The invention is directed to a seed coating composition containing a polymeric binder, a filler and a fibrous material. The seed coating composition can be formed by combining an aqueous composition pre-blend which contains a polymeric binder with a powder pre-blend which contains a filler and a fibrous material. The polymeric binder preferably contains polyvinylpyrrolidone, the filler preferably contains talc and the fibrous material preferably contains cellulose fibers.

## Claims

### Claim 1

A seed coating composition comprising:
a range from greater or equal to 70 to less than 95% by weight of polyvinylpyrrolidone, where the polyvinylpyrrolidone has a molecular weight in a range of 9,000-11,000;
a range from greater or equal to 5 to less than 30% by weight of a polymeric binder other than polyvinylpyrrolidone;
a filler comprising talc; and
a fibrous material comprising cellulose fibers having a median volume particle diameter value D(v,0.5) in a range 10-120 μm.

### Claim 2 (depends on 1)

The seed coating composition according to claim 1 wherein the polymeric binder other than polyvinylpyrrolidione comprises at least one polymer selected from the group consisting of polyvinyl acetate, vinyl acetate copolymer, polyvinyl alcohol and polyacrylate.

### Claim 3 (depends on 1)

The seed coating composition according to claim 1 comprising less than 20% by weight of water.

### Claim 4 (depends on 1)

The seed coating composition according to claim 1, wherein the filler is in particle form and wherein the ratio of filler particles to fibrous material is 0.5 to 15.0:1 by weight.
