Assessing quantitative resistance against Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape) in young plants : Assessing quantitative resistance to Leptosphaeria maculans
(2014-01-15)
Quantitative resistance against Leptosphaeria maculans in Brassica napus is difficult to assess in young plants due to the long period of symptomless growth of the pathogen from the appearance of leaf lesions to the ...
Determination of the pathogen population structure of Pyrenopeziza brassicae, causal agent of light leaf spot on brassicas
(2014)
Light leaf spot, caused by the fungal pathogen Pyrenopeziza brassicae, is currently the major disease problem in oilseed rape production in the UK. Furthermore, P. brassicae can also be found on vegetable brassicas such ...
Temperature affects the effectiveness of R gene mediated resistance against Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape)
(2014)
Phoma stem canker (Leptosphaeria maculans) is an economically important disease on oilseed rape (Brassica napus) in Europe, Australia and North America. Effective control of this disease relies on the use of two types of ...
Effects of different fungicides on the severity of phoma stem canker
(2014)
Phoma stem canker, a disease of oilseed rape (Brassica napus) caused by sibling pathogens Leptosphaeria maculans and L. biglobosa. Both pathogens follow a monocylic disease cycle that causes leaf spotting in autumn/winter ...
A systems approach to the control of strawberry powdery mildew
(2014)
A systems approach to the control of strawberry powdery mildew (Podospheara aphanis) is important, as the disease is never absent from the crop. Work reported here shows that the disease is present in the crop whether new ...
Light leaf spot (Pyrenopeziza brassicae) : a resurgent problem in the UK
(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. ...
Application of Geographic Information Systems to Identify the Oversummering Regions of Blumeria graminis f. sp. tritici in China
(2013-09)
Blumeria graminis f. sp. tritici, the pathogen that causes wheat powdery mildew, can oversummer as mycelia or conidia on leaves of volunteer wheat plants in cool mountainous areas in China. In this study, the regions in ...
The importance of asymptomatic infection in sustainable crop protection
(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 ...
Pathogenicity of leptosphaeria maculans isolates obtained from brassica napus (oilseed rape) cultivars with the rlm7 resistance gene
(2013-08)
Isolates obtained from winter oilseed rape cultivars with the resistance gene Rlm7 were examined for their pathogenicity by inoculation onto cotyledons and true leaves of the susceptible cultivar Drakkar (no R gene) and ...
