Abstract
SUMMARYThe incidence of potato gangrene in the progeny from diseased parent tubers after damage and storage at 4–6dGC was found to depend, to a large extent, on the haulm treatment carried out four weeks prior to harvest. There was a marked reduction in gangrene incidence in tubers from plots where the haulm was pulled out and removed instead of cut and removed or burnt off. This reduction is considered to result from a lowering of the level of fungal inoculum on the tuber surface rather than through a difference in tuber maturity. The incidence of gangrene was not reduced by mancozeb (Dithane 945) foliar sprays during the growing season nor was there any difference between the chemicals (sodium chlorate and sulphuric acid) used to burn off the haulms.
