Abstract
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.
