| Abstract:
Under U.K. conditions, in the virtual absence of soil and airborne inoculum and of naturally contaminated seeds, inoculation of healthy seed with A. niger conidia resulted in an increased incidence of black mould in the field and in stored bulbs. However, seed samples from tropical countries, contaminated with A. niger, transmitted the pathogen. In the Sudan, in addition to being seedborne, the fungus is soil and airborne. Seed treatments reduced the incidence of storage black mould in crops grown on land not previously used for onion production, but not sufficiently to provide complete control. Integrated strategies to control black mould on stored tropical onions are discussed. | |
