- Abstract:
- ?In order to predict the development of soybean Sclerotinia sclerotiorum accurately and timely,the occurrence of sclerotia at fixed point in Sanjiang Plain from 2004 to 2012 was surveyed,and the relations between the incidence of sclerotia stem rot and 6 meteorological factors at soybean flowering as well as the apothecium number was studied by stepwise regression and path analysis.And the stepwise regression prediction model of soybean sclerotia stem rot was established.Results showed the precipitation,average temperature and apothecium number in July had vital impact on the incidence of soybean sclerotia.The prediction model could forecast the occurrence of sclerotia for about 20 days in advance,and the forecasting incidence was basically consistent with the actual results in 2012.
