Impacts of climate change on phoma stem canker and light leaf spot on UK oilseed rape
(2011)
To illustrate impacts of climate change on plant disease epidemics, an oilseed rape crop growth model, and weather-based disease forecasting models for phoma stem canker (Leptosphaeria maculans) and light leaf spot ...
Effects of Leptosphaeria maculans race structure and fitness cost of virulence on management of phoma stem canker of oilseed rape
(2011)
Fitness of virulent (avrLm1 and avrLm4) or avirulent (AvrLm1 and AvrLm4) isolates of Leptosphaeria maculans on Brassica napus without the corresponding resistance genes Rlm1 and Rlm4 was investigated in controlled environment ...
Geographic variation in severity of phoma stem canker and Leptosphaeria maculans/L. biglobosa populations on UK winter oilseed rape (Brassica napus)
(2010-01)
Phoma stem canker, caused by Leptosphaeria maculans and L. biglobosa, is the most important disease of oilseed rape in Europe. Differences between L. maculans and L. biglobosa in their life-cycles enable the two species ...
Coexistence of related pathogen species on arable crops in space and time
(2006)
This review considers factors affecting the coexistence of closely related pathogen species on arable crops, with particular reference to data available at Rothamsted for Septoria tritici/Stagonospora nodorum (Mycosphaerella ...
Patterns of ascospore release in relation to phoma stem canker epidemiology in England (Leptosphaeria maculans) and Poland (Leptosphaeria biglobosa)
(2005-03)
Experiments over five growing seasons at Rothamsted (1998/99-2002/03), four seasons at Boxworth (1998/99, 1999/2000, 2001/02, 2002/03) in England (Leptosphaeria maculans) and three seasons (1998/99-2000/01) at Poznan in ...
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), ...
