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 ...
Development and control of light leaf spot (Pyrenopeziza brassicae) epidemics in winter oilseed rape in the UK
(British Crop Protection Council, 1998)
Effects of temperature, cultivar and isolate on the incubation period of white leaf spot (Mycosphaerella capsellae) on oilseed rape (Brassica napus)
(1997-04)
When leaves of oilseed rape (cv. Cobra) were inoculated with conidial suspensions of Mycosphaerella capsellae (white leaf spot) and incubated in controlled environments, the lag period from inoculation to the appearance ...
Prospects for developing a forecasting scheme to optimize use of fungicides for disease control on winter oilseed rape in the UK
(Association of Applied Biologists, 1997)
Effects of wetness period and temperature on development of dark pod spot (Alternaria brassicae) on oilseed rape (Brassica napus)
(1996-12)
In controlled environment experiments, when oilseed rape pods or leaves were inoculated with spore suspensions of Alternaria brassicae, the maximum disease incidence (proportion of pods or leaves diseased) increased as ...
