In order to replace methyl bromide in all the uses thereof in soil or substrate treatment, the invention relates to the use of at least one sulphur compound having general formula: wherein R represents an alkenyl or alkyl radical, n is equal to 0, 1 or 2, x is a number between 0 and 4 and R' represents an alkenyl or alkyl radical or, only if n=x=0, a hydrogen or alkali-metal atom. The sulphur compounds (in particular dimethyldisulphide) can be applied according to standard soil treatment methods (by injection, spraying, dripping, sprinkling) and said compounds have no phototoxic effects.

Pesticide treatment of soils or substrates with sulphur compounds

The present invention is directed to the pesticidal treatment of stored foodstuffs, chambers, structures and works of art, using a volatile sulphur compound of general formula: in which R represents an alkyl or alkenyl radical containing from 1 to 4 carbon atoms, n is equal to 0, 1 or 2, x is a number ranging from 0 to 4, and R' represents an alkyl or alkenyl radical containing from 1 to 4 carbon atoms or, only if n=x=0, a hydrogen atom. These sulphur compounds (in particular dimethyl disulphide) are applied by nebulization directly to the material to be treated.
