An apparatus and method for fumigating stored agricultural commodities such as grain and the like, includes an applicator for porous envelopes or sachets of prepackaged pesticides of the type which react with moisture in the air and produce a toxic gas. The applicator comprises an elongate strip constructed of a flexible, porous, non-hygroscopic material. The strip has two plies which are arranged in an overlying relationship and are interconnected along a side edge thereof, and includes a plurality of seams which extend laterally across the strip and regularly interconnect the plies, and form pockets shaped for receiving the prepackaged pesticide sachets therein. The seams form a flexible hinge between adjacent pockets and interconnect the same to facilitate folding. A sachet is inserted into each pocket, the pocket is closed, and the filled applicator is deployed onto the free surface of an aggregation of stored commodity and arranged in a flat and fully extended position thereover. Water vapor in the air infiltrates the applicator and sachets and reacts with the pesticide to form a gas which permeates the commodity storage and fumigates the same. After the sachets have completely degassed, and the grain depository is vented, a free end of the applicator is grasped, and the same is longitudinally rolled or folded accordian-style along the seams, thereby quickly retreiving each of the gassed sachets, without adulterating the commodity with pesticide residue.

An applicator for prepackaged pesticide sachets having a porous envelope with a moisture activated pesticide therein, said applicator comprising: (a) an elongate flexible, porous, non-hygroscopic strip of matted adhered fibers having first and second overlying plies interconnected along one side edge thereof; and (b) a plurality of seams extending laterally across said plies and interconnecting the same; said seams forming a plurality of pockets therebetween shaped for receiving and retaining the sachets therein; each of said pockets having a closed end disposed at the one side edge of the plies, a pair of substantially parallel side edges formed by adjacently disposed seams, and an open end located at the other side edges of the plies; said pocket open end being shaped to receive one of said sachets therethrough, and closable to retain said sachet in said pocket; each of said seams interconnecting adjacent pockets and forming a flexible hinge therebetween, along which said applicator folds accordion-style for folding up a sachet filled applicator on the surface of an agricultural commodity after pesticide gassing to retrieve said sachets without adulterating the commodity with pesticide residue.
