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)
Sporulation of Pyrenopeziza brassicae (light leaf spot) on oilseed rape (Brassica napus) leaves inoculated with ascospores or conidia at different temperatures and wetness durations
(2002-10)
In controlled environment experiments, sporulation of Pyrenopeziza brassicae was observed on leaves of oilseed rape inoculated with ascospores or conidia at temperatures from 8 to 20degreesC at all leaf wetness durations ...
Effects of timing of Leptosphaeria maculans ascospore release and fungicide regime on phoma leaf spot and phoma stem canker development on winter oilseed rape (Brassica napus) in southern England
(2002-08)
At Rothamsted during 1997/98, 1998/99 and 1999/2000 winter oilseed rape growing seasons, numbers of air-borne ascospores of Leptosphaeria maculans were often > 4 m(-3) from autumn (September/October) to spring (April/May), ...
Simulation of vertical spread of plant diseases in a crop canopy by stem extension and splash dispersal
(2002-06-01)
Upward displacement of light leaf spot lesions by winter oilseed rape stem extension and dispersal of Pyrenopeziza brassicae conidia by rain-splash were both incorporated into a model to describe vertical spread of light ...
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 ...
Improved PCR-based assays for pre-symptomatic diagnosis of light leaf spot and determination of mating type of Pyrenopeziza brassicae on winter oilseed rape
(2002-05)
An existing PCR-based method for diagnosis of the winter oilseed rape (Brassica napus ssp oleifera) fungal pathogen Pyrenopeziza brassicae (cause of light leaf spot) was improved by the development of a pair of primers ...
Changes in populations of the eyespot fungi Tapesia yallundae and T. acuformis under different fungicide regimes in successive crops of winter wheat, 1984-2000
(2002-04)
Effects of regular treatments with the fungicides carbendazim and prochloraz applied to whole plots divided into subplots with different initial population mixtures of carbendazim-sensitive or carbendazim-resistant Tapesia ...
Modelling the daily progress of light leaf spot epidemics on winter oilseed rape (Brassica napus), in relation to Pyrenopeziza brassicae inoculum concentrations and weather factors
(2002-02-15)
The progress of light leaf spot (Pyrenopeziza brassicae) epidemics on winter oilseed rape was monitored in 1998/99 and 1999/2000 at Rothamsted, and weather factors and P. brassicae ascospore concentrations were recorded ...
Factors affecting the development of Botrytis cinerea (grey mould) on linseed (Linum usitatissimum) buds, flowers and capsules
(2002)
A key was produced to describe 10 stages of development of linseed buds, flowers and capsules. Botrytis cinerea conidia germinated more rapidly and germ tubes grew longer on linseed stigmas, petals and mature senescing ...
