Abstract
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 include 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.
Claims27
An agrochemical composition comprising:
- (a) an unactivated water-activated film-forming polymer;
- (b) seeds;
- and
- (c) an unactivated water-activated chromagen effective for tinting the composition when contacted with water;
- whereby activation of the polymer is visually indicated by the chromagen.
An agrochemical dry particulate composition, comprising:
- (a) about 3 to 20 wt % unactivated water swellable starch;
- (b) about 10 to 20 wt % seeds;
- (c) about 0 to 50 wt % plasticizer;
- (d) about 10 to 50 wt % filler;
- and
- (e) an amount of an unactivated water-activated chromagen effective for tinting the composition when contacted with water, whereby activation of the polymer is visually indicated by the chromagen.
A composition comprising:
- (a) an unactivated water-activated film-forming polymer;
- and
- (b) an unactivated water-activated chromagen effective for tinting the composition when contacted with water;
- whereby, activation of the polymer is visually indicated by the chromagen.
