Abstract: Wheat scab caused by Gibberella zeae is a typical climatedependent dise- ase.The incidence degree depends largely on the weather conditions(tempera- ture,rainfall,raindays,RH,and sunhours)between late April and ear May, when wheat plants are in the heading-flowering stage.This paper presents a mathematical model used in forecasting the incidence of this disease.The multifactor comprehensive correlation method is used to establish a foreca- sting equation which was found to have a goodness of fit of 95.6%.
