The roles of ascospores and conidia of Pyrenopeziza brassicae in light leaf spot epidemics on winter oilseed rape (Brassica napus) in the UK
(2001)
Ascospores of Pyrenopeziza brassicae were produced in apothecia (cup-shaped ascomata) on oilseed rape debris. The conidia, which were morphologically identical to the ascospores, were produced in acervular conidiomata on ...
Factors affecting development of phoma canker (Leptosphaeria maculans) on stems of winter oilseed rape (Brassica napus) in southern England
(2001)
In winter oilseed rape experiments at Rothamsted in 1997/98 (cvs Lipton and Capitol), 1998/99 (cv. Apex) and 1999/2000 (cvs Apex, Lipton and Capitol), development of crown canker and phoma stem lesions in spring was related ...
Improving stem canker control in winter oilseed rape by accurate timing of fungicide applications based on disease forecasting
(HGCA, 2001)
This three year project focused on improving strategies for control of canker (Leptosphaeria maculans) in winter oilseed rape. There were three main objectives, which were addressed using historical data and field experiments: ...
Effects of temperature on germination and hyphal growth from ascospores of A-group and B-group Leptosphaeria maculans (phoma stem canker of oilseed rape)
(2001)
Ascospores of both A-group and B-group Leptosphaeria maculans germinated at temperatures from 5-20degreesC on distilled water agar or detached oilseed rape leaves. After 2 h of incubation on water agar, some A-group ...
Pathogenicity of Verticillium dahliae isolates to spring linseed cultivars
(British Crop Protection Council, 2000-11)
A comparison of modelling methods for forecasting light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape in the UK
(British Crop Protection Council, 2000-11)
Yield responses to control of pasmo (Mycosphaerella linicola) in winter linseed
(British Crop Protection Council, 2000-11)
Relationships between phoma leaf spot and development of stem canker (Leptosphaeria maculans) on winter oilseed rape (Brassica napus) in southern England
(2000-10)
Models were constructed to describe the relationships between incidence of phoma leaf spot at different growth stages in autumn/winter or early spring and incidence of stem canker (basal canker or stem lesions) in summer ...
Epidemiology in relation to methods for forecasting light leaf spot (Pyrenopeziza brassicae) severity on winter oilseed rape (Brassica napus) in the UK
(2000-09)
Pyrenopeziza brassicae, cause of light leaf spot of oilseed rape, has a complex polycyclic life cycle. It can be difficult to control light leaf spot in winter oilseed rape in the UK since it is not easy to optimise fungicide ...
Effects of temperature and wetness duration on conidial infection, latent period and asexual sporulation of Pyrenopeziza brassicae on leaves of oilseed rape
(2000-08)
Experiments in controlled environments were carried out to determine the effects of temperature and leaf wetness duration on infection of oilseed rape leaves by conidia of the light leaf spot pathogen, Pyrenopeziza brassicae. ...
