Development and validation of a model to describe the progress of phoma stem canker epidemics in England and France
Leptosphaeria maculans causes phoma stem canker, the most serious disease on winter oilseed rape in Europe. This paper reprts the validation of a mechanistic model, designed to describe the progress of phoma stem canker epidemics, as they go through different stages: ascospore production, leaf infection, phoma leaf spot development, growth of the pathogen down the leaf petiole and stem canker development. Severity of epidemics differs between seasons, between regions and between individual farms, depending on wether and agronomic factors. Therefore, a wide range of independent data (not used to construct the model), originating from Rothamsted (2003-2004 and 2004-2005 seasons, incorporating different cultivars) and Boxworth (ADAS, 2003-2004 and 2000-2001 seasons incorporating different seed rates and sowing dates) in the UK and Thiverval-Grignon (2003-2004 season) in France were used to validate the model. From a total of 14 data sets the model fitted well to 9 data sets.
