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 ...
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 ...
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)
Oilseed rape : disease development, forecasting and yield loss relationships
(HGCA, 1996-02)
A series of fourteen replicated plot scale experiments was established between 1991 and 1994 to determine the effect of disease on the yield of winter oilseed rape and the economic threshold and optimum fungicide timings ...
