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 ... -

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 ... -
Empirical models for prediction of regional light leaf spot (Pyrenopeziza brassicae) incidence on winter oilseed rape in the UK
Welham, S.J.; Turner, J.A.; Fitt, Bruce D.L.; Gladders, P.; Sutherland, K.G. (1998)Empirical models have been used to forecast plant disease epidemics and guide spray decisions. Light leaf spot (Pyrenopeziza brassicae) is a serious disease of winter oilseed rape in the UK, showing seasonal and regional ... -
Epidemiology, forecasting and management of winter oilseed rape diseases in the UK
Fitt, Bruce D.L.; Gladders, P.; Sutherland, K.G.; Turner, J.A.; Welham, S.J. (1999)Survey results show that the most serious diseases on winter oilseed rape in the UK are light leaf spot (Pyrenopeziza brassicae) and stem canker (Leptosphaeria maculans), then stem rot (Sclerotinia sclerotiorum) and dark ... -
Impact of climate change on diseases in sustainable arable crop systems : CLIMDIS

Impacts of climate change on wheat anthesis and fusarium ear blight in the UK
Madgwick, J.W.; West, Jon S.; White, R.P.; Semenov, M.A.; Townsend, J.A.; Turner, J.A.; Fitt, Bruce D.L. (2011)Climate change will affect both growth of agricultural crops and diseases that attack them but there has been little work to study how its impacts on crop growth influence impacts on disease epidemics. This paper investigates ... -
Improving strategies to control stem canker in the UK
Gladders, P.; Fitt, Bruce D.L.; Turner, J.A. (1999)The fungicides difenoconazole, flusilazole + carbendazim, prochloraz + carbendazim and tebuconazole applied as two or four spray treatments at full or half dose gave good control of phoma leaf spot on canker-susceptible ... -

Evans, Neal; Burlakoti, Rishi R.; Gladders, Peter; Ritchie, Faye; Turner, J.A.; Kloppel, Coretta; Fitt, Bruce D.L. (2014)Since 2006, the incidence and severity of light leaf spot (Pyrenopeziza brassicae) in winter oilseed rape in the UK has increased so that the disease is now the main disease concern for growers with respect to yield loss. ... -
