| Abstract: | The control effect and safety of Horizon 43% SC on Rice false smut were studied for 2 years in succession. The field trial results showed that the Rice false smut could be effectively controlled by a continuous spraying two times at the dosage of 135～225 g·hm~(-2) of Horizon 43% SC which sprayed at an internal of 10 days at the beginning of rice heading stage.The control effect of diseased grains could be up to 92.1%～98%, and the control effect of disease index was 95.3%～99.2%,and the yield increase by 23.1～30.2%, and safe to rice. |
