Phoma stem canker disease on oilseed rape (Brassica napus) in China is caused by Leptosphaeria biglobosa ‘brassicae’
(2014-12-01)
Phoma stem canker of oilseed rape (Brassica napus) is a globally important disease that is caused by the sibling ascomycete species Leptosphaeria maculans and L. biglobosa. Sixty fungal isolates obtained from oilseed rape ...
Factors contributing to the holistic control of strawberry powdery mildew

Leptosphaeria spp., phoma stem canker and potential spread of L. maculans on oilseed rape crops in China : Phoma stem canker on oilseed rape in China
(2014-06)
In China, the incidence of phoma stem canker observed in pre-harvest surveys from 2005 to 2012 was greater on winter oilseed rape in provinces in central China (in May) than on spring oilseed rape in north China (in August). ...
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 ...
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 ...
Effects of host resistance on maturation of pseudothecia of Leptosphaeria maculans and L. biglobosa (cause of Phoma stem canker) in Brassica napus (oilseed rape)
(2013-08)
The stem canker epidemics are initiated in autumn by air-borne ascospores produced in pseudothecia on infected crop debris from previous crops. This study aimed to investigate the effects of cultivar resistance and ...
Leptosphaeria spp. and Phoma stem canker on oilseed rape in China
(2013-08)
In China, the incidence of phoma stem canker observed in pre-harvest surveys from 2005 to 2012 was greater on winter oilseed rape in provinces along the Yangtze River (in May) than on spring oilseed rape in north China (in ...
Pathogenicity of Leptosphaeria biglobosa to oilseed rape (Brassica napus) cultivars differing in resistance against Leptosphaeria maculans
(2013-08)
Field and controlled environment experiments were done to examine the pathogenicity of L. biglobosa on cultivars with good resistance (carrying the Rlm7 gene) or moderate resistance (carrying the Rlm4 gene) against L. ...
The role of chasmothecia in the initiation of epidemics

Analysing virulent and avirulent Leptosphaeria maculans isolates to understand R gene-mediated resistance in Brassica napus
(2012-10)
Phoma stem canker (Leptosphaeria maculans) is a major disease on oilseed rape (Brassica napus) in Europe (e.g. it causes losses to UK farmers of > £100M p.a.). Single major gene resistance (R) in B. napus against L. maculans ...
