Effects of stem canker (Leptosphaeria maculans) and light leaf spot (Pyrenopeziza brassicae) on yield of winter oilseed rape (Brassica napus) in southern England
(2000-08)
The relationships between yield loss and incidence or severity of stem canker and light leaf spot in winter oilseed rape were analysed by correlation and regression analyses, using data from experiments at Rothamsted, ...
Effects of diseases on the growth and yield of spring linseed (Linum usitatissimum), 1988-1998
(2000-06)
In spring linseed field experiments with fungicides at Rothamsted from 1988 to 1998, substantial yield losses associated with diseases occurred in three years and slight losses could be associated with diseases in other ...
Influence of simulated rain on dispersal of rust spores from infected wheat seedlings
(2000-03-10)
Spores of both Puccinia recondita f sp, tritici and P striiformis (brown rust and yellow rust of wheat) are thought to be primarily dispersed by wind. The results of experiments, using a rain simulator with uniform drop ...
Modelling the progress of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in relation to leaf wetness and temperature
(2000)
Light leaf spot (Pyrenopeziza brassicae) is a polycyclic disease of winter oilseed rape (Brassica napus). Airborne ascospores are thought to start the epidemics, which then progress through repeated infections caused by ...
