Asymptomatic infection of winter and spring barley by Rhynchosporium secalis: effects and implications for epidemiology and host resistance
Atkins, Simon D.; Stonard, J. F.; Fraaije, B. A.; Lucas, J. A.; Fitt, Bruce D.L.; Newton, A. C. (ICARDA, 2010) -
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 ... -
The importance of asymptomatic infection in sustainable crop protection
Newton, A. C.; Fitt, Bruce D.L.; Werner, Peter; Harrap, D.; Southgate, James; Ashworth, M.; Atkins, Simon D.; Looseley, M. E. (2013-08)Scald or Rhynchosporium, caused by the fungus Rhynchosporium commune, is difficult to control with fungicides and severe epidemics may appear suddenly. Its epidemiology is not well understood as it is based on disease ... -
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 ... -
Resistance, epidemiology and sustainable management of Rhynchosporium secalis populations on barley
Zhan, J.; Fitt, Bruce D.L.; Pinnschmidt, H. O.; Oxley, S. J. P.; Newton, A. C. (2008-02)Rhynchosporium secalis is one of the most destructive pathogens of barley worldwide, causing yield decreases of up to 40% and reduced grain quality. Rhynchosporium is a polycyclic disease. Primary inoculum includes conidia ... -
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 ... -
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 ...
