Evidence for the greater susceptibility of seeds of higher oil content to methyl bromide is reviewed. Oils increase the sensitivity of seeds to the fumigant at higher moisture contents by making the water more readily available, probably by blocking sorptive substrates. The oil may also act as a reservoir for methyl bromide, so that oily seeds are subject to more severe delays during germination than are less oily seeds. The conditions of moisture content and dosage under which the oily seeds, carrot, rape, cabbage and radish, may be treated, are established, as is the range of oil contents in lucerne, a seed not subject to selection for this character.
