Abstract
A delivery system for an agriculturally active chemical comprises a body or carrier portion including a first water dispersible agriculturally inert and essentially nontoxic composition containing a predetermined aliquot of the agriculturally active chemical. The body or carrier portion has a predetermined size and a predetermined 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 aliquot of the agriculturally active chemical is an amount of the agriculturally active chemical effective to terminate functioning of a target agricultural pest upon application of the agriculturally active chemical to soil or water via the delivery system. The agriculturally active chemical can take the form of a biocide such as an insecticide, fungicide or nemacide. More particularly, the agriculturally active chemical is a compound taken from the group consisting of dimethoate, vydate, vendex, metasystox-R, fluvalinate and kethane, invermectin, propoxur, chlorpyrifos, diazinon, malathion, carbaryl, fenvalerate, methomyl, acephate, permethrins, and diflubenzuron.
