Control Effect of 30% Pyraclostrobin + Fludioxonil on Wheat Fusarium Head Blight
Abstract：Fusarium head blight is an important disease in wheat. To screen for suitable and efficient control agents, this study investigated the efficacy and yield-increasing effects of pyraclostrobin + fludioxonil compared with traditional agents tebuconazole + prochloraz on wheat fusarium head blight. The results showed that spraying 30% pyraclostrobin + fludioxonil twice during the wheat anthesis period achieved a disease control efficiency of 90.43%, which was 6.75 percentage points higher than the control agent's 83.68% efficiency; the disease index control efficiency reached 93.56%, which was 2.79 percentage points higher than the control agent's 90.77% efficiency; the yield reached 511.2 kg/667m2, which was 27.39% higher than the water control and 7.98% higher than the control agent treatment. These results indicate that pyraclostrobin + fludioxonil has good control effect on wheat fusarium head blight and significant yield-increasing effects, and it is recommended to be widely promoted as a main recommended agent in production.
