A fumigant for wood parasitic nematodes which comprises methyl iodide dissolved in liquefied carbon dioxide. The methyl iodide is used in place of methyl bromide, use of which has been restrained worldwide because it is regarded as a substance causative of ozonosphere depletion. The fumigant for wood parasitic nematodes may be one which comprises a combination of the methyl iodide and one or more compounds selected from the group consisting of sulfuryl fluoride, methyl isothiocyanate, phosphines, ethylene oxide, carbonyl sulfide, and propylene oxide. Also provided is a method of wood fumigation characterized by using any one of these fumigants to kill wood parasitic nematodes.

La présente invention décrit un fumigant contre les nématodes parasites du bois qui comprend de l~iodure de méthyle dissous dans du dioxyde de carbone liquéfié. L~iodure de méthyle remplace le bromure de méthyle, dont l'utilisation est réglementée au niveau mondial du fait de son classement en tant que substance appauvrissant l~ozonosphère. Le fumigant contre les nématodes parasites du bois peut inclure un mélange d~iodure de méthyle et d~un ou plusieurs composés sélectionnés dans la liste suivante : fluorure de sulfuryle, isothiocyanate de méthyle, phosphines, oxyde d~éthylène, sulfure de carbonyle, et oxyde de propylène.
