摘 要: | 目的]筛选防治赤霉病的有效药剂。方法]采用室内配方筛选试验和田间药剂防治试验研究咪鲜胺、戊唑醇及二者混配对对小麦赤霉病的防治效果。结果]咪鲜胺、戊唑醇及咪鲜胺与戊唑醇复配可抑制赤霉病菌菌丝的生长,且咪鲜胺与戊唑醇复配无拮抗作用,按试验配比复配时,以咪鲜胺+戊唑醇(2∶1)的增效作用最好,增效系数为1.58。在供试的几种药剂中,咪鲜胺+戊唑醇(2∶1)复配剂对小麦赤霉病的田间防效较好,其病穗防效和病指防效分别为78.21%和86.72%,显著高于其他5种药剂。结论]试验结果为生产中小麦赤霉病的药剂防治提供了参考。

Abstract: | Objective] The aim was to screen out effective pesticides to control wheat scab.Method] We studied control effect of prochloraz, pebuconazole and their mixture on wheat scab (Fusarium graminearum) by indoor formulation screening test and field control test.Result] The prochloraz, tebuconazole and mixtures of them both could inhibit the mycelium's growth of Fusarium graminearum and mixtures had no antagonism.When prochloraz was mixed with tebuconazole as 2∶1, it had the best additive effects (SR=1.58).The mixtures also showed excellent effect which was 78.21% and 86.72% to Fusarium in the field, higher than the other 5 pesticides significantly.Conclusion] The result provided reference for chemical control of wheat scab. |
