A delivery system for a biocide or fertilizer comprises a body or carrier portion including a first water dispersible agriculturally inert and essentially nontoxic composition containing a predetermined amount of the biocide or fertilizer. The body or carrier portion has a predetermined size and shape. The delivery system also comprises a protective coating, about the body portion, of a second water dispersible agriculturally inert and essentially nontoxic composition. The amount of biocide used is that amount which terminates the functioning of a target agricultural pest upon application of the biocide to soil or water via the delivery system. The biocide can take the form of a biocide such as an insecticide, fungicide, nematocide or herbicide. Compositions according to the present invention including a water dispersible cellulose ether, cellulose fiber and an effective amount of a biocide or fertilizer are also described. Additional components may be added to the composition according to the present invention.

Water dispersible delivery system for an agriculturally active chemical

The present invention relates to unexpected or surprising discoveries in the field of biodegradable, water-dispersible formulations and materials and methods for influencing their rate of dispersibility in water. In particular, the present invention relates to the unexpected discovery that the inclusion of effective amounts of short length cellulose fibers dispersed throughout a water soluble cellulose ether binder will result in a retardation or slowing of the water dispersibility of the formulation relative to a formulation containing long or long and short cellulose fibers in a cellulose ether binder. In an additional aspect, the present invention relates to the discovery that the inclusion of effective amounts of long length cellulose fibers dispersed throughout a water soluble cellulose ether binder will result in an enhancement or hastening of the water dispersibility of the formulation relative to a formulation containing a cellulose ether binder which does not contain long cellulose fibers. In still a further aspect, the present invention relates to the discovery that the inclusion of effective amounts of a gas-releasing agent increases the rate of water-dispersibility relative to formulations containing only a cellulose ether binder.
