Preliminary Study on Control Effects of Five Kinds of Fungicides against Wheat Scab

摘要

[Objective] This paper was to improve the current status that the fungicide carbendazim as the single agent was largely applied in the control against wheat scab. [Method] Five kinds of fungicides on sales and new agents against wheat scab were selected for field trials. [Result] 25% JS399-19 SC,30% tebuconazole·thiram WP,75% trifloxystrobin·tebuconazole WDG and 10% ZJ0712 JG could effectively control wheat scab,and the control effects of one time or two times application were better than control agent carbendazim; the control efficacy of two times application was improved in different degrees against one time application. [Conclusion] The paper provided basis for the control against wheat scab.
