"ABSTRACT OF THE DISCLOSURE" The invention is directed to the fumigation of soils, enclosed spaces, agricultural products and other commodities, etc., using compositions which decompose to form carbon disulfide and certain other biocidal materials. Such fumigation can be used to control bacteria, fungi, insects, nematodes, rodents, and weeds. Fumigant compositions are described herein as "thiocarbonates," including, without limitation, salts of trithiocarbonic acid and tetrathiocarbonic acid, and composi- tions having empirical formulae intermediate to these acid salts (such as MCS3.7, wherein M is a divalent metal ion). The compositions are generally water soluble and can be prepared, stored, and used in aqueous solutions. Thiocar- bonate solutions of the invention are stable during prolonged periods of storage in a closed container, exhibit a low vapor pressure, and are not flammable. For soil fumigation, thiocarbonates can be mixed with fertilizers to provide a multi-functional application.
