The penetration of methyl bromide into bags of wheatfeed has been investigated in experimental fumigations at atmospheric pressure and by various techniques in which reduced pressures are used. In a series of four‐hour treatments the highest penetration factors were obtained when, after allowing an initial period of one hour at reduced pressure, the pressure was restored to atmospheric The effects of total pressure and of sorption on the diffusion of methyl bromide, carbon dioxide and hydrogen cyanide along a column of wheatfeed have been studied.
