Abstract
ONE of the most serious pests of tobacco in Southern Rhodesia is the eelworm, Heterodera marioni. Control of this organism is effected by injecting the soil, by means of a plunger-type injector, with ethylene dibromide or a dichloropropene–diehloropropane mixture. During the 1951–52 growing season, it has been estimated that the latter fumigant has produced ‘off-odours’ in approximately five per cent of the tobacco crop. These odours first become apparent during the curing process, and persist through all subsequent stages of processing. Impurities in the fumigant mixture have been shown to be responsible for this tainting and have been isolated and characterized by the methods described below.
