Effects of timing of Leptosphaeria maculans ascospore release and fungicide regime on phoma leaf spot and phoma stem canker development on winter oilseed rape (Brassica napus) in southern England
(2002-08)
At Rothamsted during 1997/98, 1998/99 and 1999/2000 winter oilseed rape growing seasons, numbers of air-borne ascospores of Leptosphaeria maculans were often > 4 m(-3) from autumn (September/October) to spring (April/May), ...
Maturation of ascospores of A-group and B-group Leptosphaeria maculans (stem canker) on winter oilseed rape debris
(British Crop Protection Council, 2002)
Ascospores of both A-group and B-group L. maculans matured faster at 15-20degreesC than at 5-10degreesC. At 5-10degreesC, maturation of B-group ascospores was slower than that of A-group ascospores but there was no difference ...
New perspectives on the epidemiology and management of phoma stem canker of winter oilseed rape in England
(British Crop Protection Council, 2002)
The epidemiology of phoma stem canker (Leptosphaeria maculans) on winter oilseed rape will be discussed in relation to results of experiments comparing fungicide regimes in southern England. Factors affecting the severity ...
