Abstract
Thixotropic fumigant compositions comprising liquid haloaliphatic hydrocarbon based fumigants and silica gelling agents may be stabilized through the use of an epoxide stabilizing agent and by controlling the purity of the raw materials such that the haloaliphatic hydrocarbon contains alcoholic impurities such as methyl alcohol in methyl bromide at a level of not more than about 200 ppm and such that the composition contains an initial water content of not more than about 500 ppm. Such compositions have utility as soil fumigants having significantly improved shelf life relative to prior gelled fumigant compositions for use in the control of nematodes, weeds, and weed seeds.
