<p>An inexpensive composition effective for forming a long lasting, erosion controlling, germination promoting, pliable film over bare soil. The composition may be formulated in dry or liquid form and applied as either a dry powder or liquid dispersion. The composition includes at least a major proportion of gelatinized starch and a plasticizer. The composition may further inlcude a fungicide, a bactericide, a micronutrient, and a filler. The liquid form will also include sufficient solvent - typically water - and may further include a thickener and an emulsifier for purposes of controlling settling of the components and maintaining a uniform dispersion.</p> |
