Altered distribution and life cycles of major pathogens in Europe
Evans, N.; Gladders, P.; Fitt, Bruce D.L.; Tiedemann, A. V. (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. ... -
Arable crop disease control, climate change and food security
Fitt, Bruce D.L.; Evans, Neal; Gladders, P.; Hughes, David; Jeger, M.J.; Turner, J.A.; West, Jon S. (Association of Applied Biologists, 2011)Global food security is threatened by crop diseases that account for average yield losses of 16%. Climate change is exacerbating threats to food security in much of the world, emphasising the need to increase food production ... -
Autumn sowing increases severity of pasmo (Mycosphaerella linicola) on linseed in the UK
Perryman, S. A. M.; Gladders, P.; Fitt, Bruce D.L. (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 ... -
Climate change and phoma stem canker
Evans, Neal; Fitt, Bruce D.L.; Gladders, P. (HGCA, 2008)Climate change affects plants in natural and agricultural ecosystems throughout the world but little work has been done on the effects of climate change on plant disease epidemics. To illustrate such effects, a weather-based ... -

Controlling crop disease contributes to both food security and climate change mitigation
Mahmuti, M.; West, Jon S.; Watts, J.; Gladders, P.; Fitt, Bruce D.L. (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 ... -
Controlling crop disease to mitigate climate change
West, Jon S.; Mahmuti, M.; Watts, J.; Townsend, J.; Gladders, P.; Fitt, Bruce D.L.; Stockdale, E.; Martindale, W. (Association of Applied Biologists, 2009) -
Development and control of light leaf spot (Pyrenopeziza brassicae) epidemics in winter oilseed rape in the UK
Sutherland, K.G.; Fitt, Bruce D.L.; Steed, J. M.; Welham, S.J.; Gladders, P.; Turner, J.A. (British Crop Protection Council, 1998) -
Development of a decision support system for phoma and light leaf spot in winter oilseed rape (PASSWORD project)
Gladders, P.; Dyer, Chris; Fitt, Bruce D.L.; Evans, Neal; van den Bosch, Frank; Steed, J. M.; Baierl, A.; Turner, J. D.; Walters, K.; Northing, P.; Sutherland, K.G.; Campbell , S.; Ellerton, D.; Selley, Andrew; Hall, B.; Naylor, D.; Parker, C. (HGCA, 2004-12-14)Pests and diseases in winter oilseed rape cause serious loss of yield and quality. Losses, predominantly from diseases, are estimated to exceed £80 million/annum in some years. These losses have occurred despite an annual ... -
Development of a DSS for diseases and pests in winter oilseed rape
Sutherland, J.G; Evans, Neal; Fitt, Bruce D.L.; Gladders, P.; Morgan, D.; Northing, P.; Turner, J.A.; Walters, K.F.A; Parker, C. (2002) -
Development of a system for forecasting severe light leaf spot in winter oilseed rape
Sutherland, K.G.; Fitt, Bruce D.L.; Gladders, P.; Steed, J. M.; Turner, J.A.; Welham, S.J. (1998)In the UK, an estimated £3-9 M are spent each year on fungicides to control winter oilseed rape diseases, but losses in excess of £30 M still occur [1]. Light leaf spot (Pyrenopeziza brassicae) is one of the major diseases ... -
Diagnosis of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in the UK
Fitt, Bruce D.L.; Doughty, K.J.; Gladders, P.; Steed, J.M.; Sutherland, K.G. (1998-10)Light leaf spot lesions were generally first observed as light green areas on leaves of UK winter oilseed rape crops in January or February and later became brittle and bleached. Elongated lesions, which were brown with ... -
Diseases of winter linseed : occurrence, effects and importance
Perryman, S. A. M.; Gladders, P.; Barrow, A.; Simons, B.; Fitt, Bruce D.L. (HGCA, 2001)In 1998, a survey of the incidence and severity of diseases was carried out on 30 crops of winter linseed at early flowering and again at crop maturity.
