As per International Plant Protection conversion Methyl bromide is an approved fumigant which can be used for treating export cargo containing wooden packing materials. Fumigants only control existing infestations in the cargo they do not provide any residual protection against subsequent re-infestation. Consequently timber treated by fumigation must be packed in container or shipped within 21 days of treatment. During this 21 day period it should be stored safely or cross infestation may occur. After Completion of Methyl Bromide Fumigation when agri products are taken for repacking care should be taken to maintain the repacking area pest free and good hygienic practices should be followed in order to avoid cross infestation between fumigated and unfumigated cargo.
