摘要：

由假禾谷镰刀菌(Fusarium pseudograminearum)侵染引起的小麦茎基腐病是当前小麦生产上的重要病害,因尚未选育出能够有效抵抗小麦茎基腐病的高抗小麦品种,当前主要以化学药剂防控为主。粉唑醇和丙硫菌唑是目前生产上广泛应用的杀菌剂,因其抑菌效果优异而广受好评。明确粉唑醇与丙硫菌唑复配剂对茎基腐病的防治效果对有效防控小麦茎基腐病及延长杀菌剂的使用寿命具有重要的意义。本研究使用孙云沛共毒系数法开展了粉唑醇与丙硫菌唑的二元复配及其对假禾谷镰刀菌的抑菌效果评价。结果表明,粉唑醇和丙硫菌唑复配对假禾谷镰刀菌表现出了较强的抑菌活性,并在一定质量比范围内表现出显著的增效作用,且当质量比为1∶9和4∶6时,其共毒系数最大并对假禾谷镰刀菌的菌丝生长和孢子萌发均表现出增效作用。同时,温室盆栽试验进一步表明,粉唑醇和丙硫菌唑复配后对小麦茎基腐病具有优异的防治效果,其中质量比1∶9时的防治效果最为显著,为86.53%,优于氟环唑(65.21%)、氟啶胺(42.28%)、粉唑醇(52.38%)、戊唑醇(31.54%)和丙硫菌唑(63.64%)单剂的防治效果。

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
