The present paper dealt with the forecast of the epidemics of the rice blast, pyricularia oryzae. The data from 1962 to 1987 were collected from 4 counties, i.e., Jianyan, Ninhua, Shanghan and Liancheng of Fujian province.The 9 forecasting objects of the disease were included in the research, that were the occourring time, the infected rate, the index, the infected area of the rice leaf blast, etc.The 9 series of the forecasting equations for the objects of the disease were set up by the means of the stepwise discriminant analysis.The results for the application of the equations showed that the average of the accurate rate for forecasting were 83,33%.
