Abstract: The effects of 24.1% trifloxystrobin·isomitamide seed treatment suspension (FS) on rice disease control and yield of rice were studied.The results showed that the control effect of 24.1% trifloxystrobin·isomitamide FS for seed treatment were 100% on rice seeding blight and rice seeding blast,and the control effect of rice leaf plague was 86.2%~94.5%,which can also promote the growth of rice roots and increase the tiller number and effective panicles,and improve seed setting rate in the meanwhile.Compared with CK,rice yield increased by 2 157.0~4 335.0 kg/hm².The control should be carried out under condition that the environment and climate were favorable to leaf plague and panicle neck blast,such as planting rice blast varieties and large amount of nitrogen fertilizer,should be controlled,especially after the jointing stage of rice.It was recommended to use 24.1% trifloxystrobin·isomidamide FS 20~25 mL with an addition of 2 mL of film forming agent coating for dried rice seeds per kilogram.
