Quantitative resistance to symptomless growth of Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape)
(2009-04)
Quantitative resistance to Leptosphaeria maculans in Brassica napus was investigated in field and controlled environments using cultivars Darmor (with quantitative resistance) and Eurol (without quantitative resistance). ...
Development of Oculimacula yallundae and O-acuformis (eyespot) lesions on stems of winter wheat in relation to thermal time in the UK
(2009-02)
Relationships between development of eyespot, caused by Oculimacula yallundae (OY) or O. acuformis (OA) on stems of winter wheat (cv. Avalon), and thermal time (degrees C days after sowing) were investigated in field ...
Controlling crop disease contributes to both food security and climate change mitigation
(2009)
Global food security is threatened by crop diseases that account for average yield losses of 16 per cent, with the greatest losses experienced by subsistence farmers in the developing world. Climate change is exacerbating ...
Determining frequencies of avirulent alleles in airborne inoculum of Leptosphaeria maculans using molecular assays
(2009)
Control of blackleg (phoma stem canker) disease relies on crop management, fungicides and breeding for disease resistance. Proteins encoded by these resistance genes recognize avirulence (Avr) gene products in the fungus ...
Controlling crop disease to mitigate climate change
(Association of Applied Biologists, 2009)
Altered distribution and life cycles of major pathogens in Europe
(DPG Selbstverlag, 2009)
Climate is a major determinant of crop productivity. Besides its direct impact on plant growth it has a major effect on the prevalence and incidence of plant diseases. The sensitivity of pathogens to climate is pronounced. ...
Autumn sowing increases severity of pasmo (Mycosphaerella linicola) on linseed in the UK
(2009)
Surveys and field experiments showed pasmo to be the most serious disease affecting UK winter linseed in the 1997-98, 1998-99 and 1999-2000 growing seasons. Survey data indicated that pasmo was widespread in England and ...
Analyses of air samples for ascospores of Leptosphaeria maculans and L.biglobosa by light microscopy and molecular techniques
(2009)
Spores of many fungal pathogens are dispersed by wind. Detection of these airborne inocula is important in forecasting both the onset and the risk of epiphytotics. Species-specific primers targeted at the internal transcribed ...
