Application of real-time and multiplex polymerase chain reaction assays to study leaf blotch epidemics in barley
Fountaine, J. A.; Shaw, M. W.; Napier, B.; Ward, Elaine; Fraaije, B. A. (2007-03)Leaf blotch, caused by Rhynchosporium secalis, was studied in a range of winter barley cultivars using a combination of traditional plant pathological techniques and newly developed multiplex and real-time polymerase chain ... -

Atkins, Simon D.; Stonard, J. F.; Fraaije, B. A.; Lucas, J. A.; Fitt, Bruce D.L.; Newton, A. C. (ICARDA, 2010) -
The dynamics of Rhynchosporium secalis in winter and spring barley and the role of inoculum sources
Atkins, Simon D.; Fraaije, B. A.; Lucas, J. A.; Fitt, Bruce D.L. (2008-08) -
The epidemiological importance of asymptomatic infection of winter barley by Rhynchosporium secalis and its consequences for crop protection and breeding
Atkins, Simon D.; Fitt, Bruce D.L.; Fraaije, B. A.; Harvey, S; Lynott, J.; Newton, A. C. (2010)Summary: Leaf scald (caused by Rhynchosporium secalis) is one of the most economically important diseases of barley. Data were collected from three seasons of trials using two susceptible winter barley cultivars (Sumo and ... -
Genetic basis of control of Rhynchosporium secalis infection and symptom expression in barley
Looseley, M. E.; Newton, A. C.; Atkins, Simon D.; Fitt, Bruce D.L.; Fraaije, B. A.; Thomas, W. T. B.; Keith, R.; Macaulay, M.; Lynott, J.; Harrap, D. (2012)The genetic basis of several different components of resistance to Rhynchosporium secalis in barley was investigated in a mapping population derived from a cross between winter and spring barley types. Both the severity ... -
Impacts of changing air composition on severity of arable crop disease epidemics
Fraaije, B. A.; Chandramohan, P.; Shaw, M. W.; Fitt, Bruce D.L. (2011-02)This review assesses the impacts, both direct and indirect, of man-made changes to the composition of the air over a 200 year period on the severity of arable crop disease epidemics. The review focuses on two well-studied ... -
Long-term dynamics in wheat of Phaeosphaeria nodorum and Mycosphaerella graminicola
Shaw, M. W.; Bearchell, S. J.; Fitt, Bruce D.L.; Fraaije, B. A. (2008-08) -
Long-term relationships between environment and abundance in wheat of Phaeosphaeria nodorum and Mycosphaerella graminicola
Shaw, M. W.; Bearchell, S. J.; Fitt, Bruce D.L.; Fraaije, B. A. (2008)Relationships between weather, agronomic factors and wheat disease abundance were examined to determine possible causes of variability on century time scales. In archived samples of wheat grain and leaves obtained from the ... -
Molecular diagnostics for fungal plant pathogens
McCartney, H. A.; Foster, S. J.; Fraaije, B. A.; Ward, Elaine (2003-02)Accurate identification of fungal phytopathogens is essential for virtually all aspects of plant pathology, from fundamental research on the biology of pathogens to the control of the diseases they cause. Although molecular ... -
Plant pathogen diagnostics : immunological and nucleic acid-based approaches
Ward, Elaine; Foster, S. J.; Fraaije, B. A.; McCartney, H. A. (2004)Accurate disease diagnosis and precise identification of any pathogens involved is an essential prerequisite for understanding plant diseases and controlling them effectively. Traditional methods of identifying plant ... -
Resistance to Rhynchosporium secalis in a cross between winter and spring barley
Looseley, M. E.; Newton, A. C.; Atkins, Simon D.; Fitt, Bruce D.L.; Fraaije, B. A.; Thomas, W. T. B.; Keith, R.; Macaulay, M.; Lynott, J.; Harrap, D. (2011)Winter barley types shows higher levels of field resistance to R. secalis compared to spring barley varieties. In addition, barley leaves have been shown to tolerate relatively high levels of R. secalis colonisation in the ... -
Role of inoculum sources in Rhynchosporium population dynamics and epidemics on barley.
Fitt, Bruce D.L.; Atkins, Simon D.; Fraaije, B. A.; Lucas, John A.; Newton, A. C.; Looseley, M. E.; Werner, Peter; Harrap, D.; Ashworth, M.; Southgate, James; Phillips, Huw; Gilchrist, Andrew (HGCA, 2012-04)Rhynchosporium leaf blotch of barley, caused by the fungus Rhynchosporium secalis, is of increasing importance in world agriculture. It is the most serious disease of winter and spring barley in the UK, causing substantial ... -
The role of seeds and airborne inoculum in the initiation of leaf blotch (Rhynchosporium secalis) epidemics in winter barley
Fountaine, J. M.; Shaw, M. W.; Ward, E.; Fraaije, B. A. (2010-04)Both airborne spores of Rhynchosporium secalis and seed infection have been implied as major sources of primary inoculum for barley leaf blotch (scald) epidemics in fields without previous history of barley cropping. ... -
Symptomless infection by Rhynchosporium commune in relation to control of barley leaf blotch
Atkins, Simon D.; Newton, A. C.; Fraaije, B. A.; Lucas, J. A.; Fitt, Bruce D.L. (2011)Rhynchosporium leaf blotch (caused by Rhynchosporium commune) is the most economically important disease of barley in the UK, but epidemics can be difficult to control with fungicides and the basis of cultivar resistance ... -
Wheat archive links long-term fungal pathogen population dynamics to air pollution
Bearchell, S. J.; Fraaije, B. A.; Shaw, M. W.; Fitt, Bruce D.L. (2005-04-12)We used the PCR to study the presence of two plant pathogens in archived wheat samples from a long-term experiment started in 1843. The data were used to construct a unique 160-yr time-series of the abundance of Phaeosphaeria ... -
