| Abstract: | According to the meteorological data and field investigation of rape clubroot disease incidence during 2008-2012 in Huangshan city of Anhui province, the relationship between meteorological factors and rape clubroot disease incidence was analyzed by stepwise regression and path analysis. The result showed that important climate factors affecting the disease incidence of rape clubroot obviously were the average temperature, rainfall in first ten days and rainfall in the last ten days of September. A mathematical model for forecasting of disease epidemic was set up. |
