Relationships between regional weather and incidence of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape in England and Wales
(Association of Applied Biologists, 1999)
Optimising the use of fungicides to control stem canker of oilseed rape
(1999)
Ascospores of Leptosphaeria maculans infect leaves of oilseed rape to cause leaf spots, from which the fungus can grow to infect the stem. Yield losses due to early senescence and lodging result if the stem infections reach ...
Sampling winter oilseed rape crops to assess incidence of light leaf spot (Pyrenopeziza brassicae)
(Association of Applied Biologists, 1999)
Modelling the progress of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in relation to weather criteria
(Association of Applied Biologists, 1999)
Yield loss of winter oilseed rape in relation to severity of stem canker (Leptosphaeria maculans ) in the UK
(1999)
The relationships between yield loss and incidence or severity of stem canker in winter oilseed rape were analysed using data from experiments at Rothamsted in 1991/92, Withington in 1992/93, Boxworth in 1993/94 and ...
Forecasting light leaf spot (Pyrenopeziza brassicae) of winter oilseed rape (Brassica napus) on the Internet
(Association of Applied Biologists, 1999)
Effects of temperature and wetness duration on infection of oilseed rape by ascospores of A-group or B-group Leptosphaeria maculans (stem canker)
(1999)
Phoma lesions produced on oilseed rape leaves by B-group ascospores were smaller and less distinctive than lesions produced by A-group ascospores of Leptosphaeria maculans, when leaves were inoculated with ascospore ...
Effects of light leaf spot (Pyrenopeziza brassicae) on yield of winter oilseed rape (Brassica napus)
(1998-06)
The relationship between development of light leaf spot and yield loss in winter oilseed rape was analysed, initially using data from three experiments at sites near Aberdeen in Scotland in the seasons 1991/92, 1992/93 and ...
Empirical models for prediction of regional light leaf spot (Pyrenopeziza brassicae) incidence on winter oilseed rape in the UK
(1998)
Empirical models have been used to forecast plant disease epidemics and guide spray decisions. Light leaf spot (Pyrenopeziza brassicae) is a serious disease of winter oilseed rape in the UK, showing seasonal and regional ...
Development of a system for forecasting severe light leaf spot in winter oilseed rape
(1998)
In the UK, an estimated £3-9 M are spent each year on fungicides to control winter oilseed rape diseases, but losses in excess of £30 M still occur [1]. Light leaf spot (Pyrenopeziza brassicae) is one of the major diseases ...
