A method of determining the permeability to methyl bromide of wrappers and other materials used to ship imported plants is described. Common brown (kraft), tissue, and glazed papers, and corrugated cardboard were readily penetrated by methyl bromide and could be left intact during quarantine fumigation. Tar, laminated, and wax papers, polyethylene films, masking tape, wall- board, and several other materials had comparatively low permeability. These and parchment-type papers, which ha\'e low to intermediate permeability, should be opened or removed from the commodity as long as present schedules of fumigation arc used.
