摘要: 为明确当前小麦赤霉病防控药剂的防效,探明不同药剂种类在小麦赤霉病重发生及轻发生地区防治效果差别,采用两地药剂小区试验同时测定13个农药品种对小麦赤霉病的防效。试验结果表明,在气象条件不利于小麦赤霉病发生而发病较轻的地区,参试药剂均具有较好的防效。而在气象条件适合,赤霉病重发生地区,参加试验的药剂其防效均低于70%,表现不佳。其中多菌灵及其复配药剂均对小麦赤霉病保持较高的防效,戊唑醇及其复配剂对赤霉病防效相对较差。

Abstract: To evaluate the control effect of current fungicides on wheat scab and verify the differences of control effect with different types of fungicides used in the area of heavy and light wheat scab, the control effect was measured through two simultaneous plot trails by 13 pesticides on wheat scab. The test results showed that all the fungicides had good control effect in the area with the weather conditions that were not conducive to wheat scab with the low incidence; the fungicides had poor performance and control effect was lower than 70% in the areas with weather conditions that were suitable for wheat scab with high incidence. Carbendazim and its compounding pesticide had a high control effect on wheat scab while tebuconazole and its compounding pesticide had poor control effect on scab.
