Effects of temperature and wetness duration on infection of oilseed rape leaves by ascospores of Leptosphaeria maculans (stem canker)
(1999-11)
In controlled environment experiments, ascospores of Leptosphaeria maculans (stem canker) infected oilseed rape (cv. Nickel) leaves and caused phoma leaf spots at temperatures from 8 degrees C to 24 degrees C and leaf ...
Effects of severity and timing of stem canker (Leptosphaeria maculans) symptoms on yield of winter oilseed rape (Brassica napus) in the UK
(1999-10)
The relationships between yield loss and incidence (% plants with stems affected) or severity (mean stem score, 0-4 scale) of stem canker in winter oilseed rape were analysed using data from experiments at Rothamsted in ...
Epidemiology, forecasting and management of winter oilseed rape diseases in the UK
(1999)
Survey results show that the most serious diseases on winter oilseed rape in the UK are light leaf spot (Pyrenopeziza brassicae) and stem canker (Leptosphaeria maculans), then stem rot (Sclerotinia sclerotiorum) and dark ...
Investigating the horizontal spatial spread of light leaf spot (Pyrenopeziza brassicae) of winter oilseed rape in the UK
(Association of Applied Biologists, 1999)
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 ...
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 ...
