Effects of light leaf spot (Pyrenopeziza brassicae) infection on winter survival and yield of oilseed rape (Brassica napus)
(British Crop Protection Council, 2002-11)
Effects of light leaf spot (Pyrenopeziza brassicae) infection on canopy size and yield of oilseed rape
(British Crop Protection Council, 2002-11)
Colonization of winter oilseed rape tissues by A/Tox(+) and B/Tox(0) Leptosphaeria maculans (phoma stem canker) in France and England
(2002-06)
The colonization of winter oilseed rape plants and epidemiology of phoma stem canker differed between A/Tox(+) and B /Tox(0) Leptosphaeria maculans. In France and England, where plant colonization was investigated during ...
New perspectives on the epidemiology and management of phoma stem canker of winter oilseed rape in England
(British Crop Protection Council, 2002)
The epidemiology of phoma stem canker (Leptosphaeria maculans) on winter oilseed rape will be discussed in relation to results of experiments comparing fungicide regimes in southern England. Factors affecting the severity ...
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 ...
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: ...
Optimising fungicide timing for controlling light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape in the UK
(Association of Applied Biologists, 1999)
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
