摘要

Wheat scab caused by Fusarium graminearum is increasingly severe in the middle and lower reaches of the Yangtze River region.With long-term use of single chemical pesticide,the drug resistance of F.graminearum is growing day by day.In order to reveal the inhibition effect and synergistic effect of prochloraz and tebuconazole and their mixture on F.graminearum,new compound agents for controlling wheat scab were developed.The inhibition effect and synergistic effect of prochloraz and tebuconazole mixed at seven different ratios on F.graminearum were studied.The results showed that the efficiency of the mixture was the best when the proportion of prochloraz and tebuconazole was 1∶7;the EC 50 was 0.145 36 and the synergistic coefficient was 1.853 9.The results provide a theoretical basis for development of new compound agents and effective control of wheat scab.
