The gaseous chemical compound, carbonyl sulphide, has hitherto been unknown as a fumigant for the control of insects and mites. Experiments have shown conclusively that carbonyl sulphide can be used as such a fumigant, with fumigation properties comparable to those of phosphine and methyl bromide. The effectiveness of carbonyl sulphide against insects (both adult and immature stages), mites, termites and moulds is demonstrated. In addition, its low absorbtion by grain, lower flammability than phosphine, lack of influence on seed germination, and apparent environmental safety make carbonyl sulphide particularly beneficial as a fumigant of stored grain. It may also be used to fumigate other stored produce (including perishable foodstuff), soil, timber and spaces (such as buildings) and any material likely to be infested by insects or mites, or act as a source of such infestation.
A method of controlling a pest in a stored product, timber, soil or a space, said method comprising applying a dose of carbonyl sulphide to the stored product, timber, soil or space, wherein the dose is sufficient to control said pest, and wherein said pest is selected from the group consisting of insects, nematodes, and mites.
A method of controlling a pest in an area, the method comprising applying a dose of carbonyl sulphide to the area, wherein the dose is sufficient to control the pest, and wherein the pest is selected from the group consisting of insects, nematodes, and mites.
A method for protecting a foodstuff that is consumed by a mammal, wherein the foodstuff is stored in an area, the method comprising:
