The results showed that the control effects of azadirachtin+Bt+validamycin+dimehypo on leaffolder, yellow borer, chilo suppressalis and rice sheath blight of aromatic rice, Pei-zaruanxiang and Gui-xiangzhan were the best and the yield of aromatic rice was higher, control rates of all diseases and insect pests were over 94%. In addition, for Pei-zaruanxiang, the treatment of azadirachtin+Bt+rotenone+validamycin reduced significantly these disease and pests and guaranteed the yield, control rates were all over 94%; for Gui-xiangzhan, the treatment of azadirachtin+Bt+validamycin had the same effects, the control rate of leaffolder was 93%-96%, the rest were up to 98%.
