(2) In this study, short-termforecasts of the rate of plants affected by
the rice stripe disease per pentad were conducted using three
differentmodels: stepwise regression, a back propagation neural
network, and support vector machines, the average prediction
accuracies of the three models were 77.35%, 93.75%, and
98.95%, respectively (i.e., all greater than 75%). It is feasible to
forecast the rate of RSV diseased plants in the short term by
using these three models, the forecast two pentads in advance
could accurately and effectively prevent and control disease
according to the complicated field condition and changeable
weather condition.
