Predicting light leaf spot (Pyrenopeziza brassicae) risk on winter oilseed rape (Brassica napus) in England and Wales, using survey, weather and crop information
(2004-12)
Data from surveys of winter oilseed rape crops in England and Wales in growing seasons with harvests in 1987-99 were used to construct statistical models to predict, in autumn (October), the incidence of light leaf spot ...
Modelling the progress of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in relation to leaf wetness and temperature
(2001-04)
A compartmental model was developed to describe the progress with time of light leaf spot (Pyrenopeziza brassicae) on leaves of winter oilseed rape (Brassica napus) during the autumn in the UK. Differential equations ...
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)
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 ...
Effects of stem canker (Leptosphaeria maculans) and light leaf spot (Pyrenopeziza brassicae) on yield of winter oilseed rape (Brassica napus) in southern England
(2000-08)
The relationships between yield loss and incidence or severity of stem canker and light leaf spot in winter oilseed rape were analysed by correlation and regression analyses, using data from experiments at Rothamsted, ...
Modelling the progress of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in relation to leaf wetness and temperature
(2000)
Light leaf spot (Pyrenopeziza brassicae) is a polycyclic disease of winter oilseed rape (Brassica napus). Airborne ascospores are thought to start the epidemics, which then progress through repeated infections caused by ...
