Abstract:

Wheat crown rot caused by Fusarium pseudograminearum is an important plant disease in wheat production. At present, there is no highly resistant wheat variety that can effectively resist wheat crown rot, and chemical pesticides are mainly used for its prevention and control. Flutriafol and prothioconazole are widely used fungicides in the prevention and control of wheat diseases, and are widely praised for their excellent antibacterial effects. Clarifying the control effect of the flutriafol and prothioconazole compound on wheat crown rot is of great significance for effectively controlling wheat crown rot and prolonging the service life of fungicides. In this study, the Sun Yunpei co-toxicity coefficient method was used to evaluate the binary combination of flutriafol and prothioconazole and its antibacterial effect on Fusarium pseudograminearum. The results showed that the flutriafol and prothioconazole compound showed excellent antibacterial activity against F.pseudograminearum, and showed a synergistic effect within a certain mass ratio, and when the mass ratios were 1∶9 and 4∶6, the co-toxicity coefficient was the biggest in the mycelial growth and spore germination test of F.pseudograminearum, which showed synergistic effect. Meanwhile, pot experiments further showed that the control effect of the compound agent was higher than that of the single dose, and the difference was significant, when flutriafol and prothioconazole were compounded with 1∶9, it had excellent control effects on wheat crown rot, which were 86.53%, better than epoxiconazole, fluazinam, flutriafol, tebuconazole and prothioconazole with 65.21%, 42.28%, 52.38%, 31.54% and 63.64% control effects, respectively.

Key words: flutriafol, prothioconazole, fungicide mixture, pot experiment, wheat crown rot
