[目的]筛选出对小麦叶锈病有效的防治药剂。[方法]用6种杀菌剂在小麦拔节期喷雾1次,10 d后在小麦抽穗期再喷雾1次。[结果]第2次喷雾20 d后调查,75%肟菌·戊唑醇WG、43%戊唑醇SC和12.5%烯唑醇WP对小麦叶锈病的防效均大于99.00%;30 d后防效分别为98.62%、96.11%和91.05%,其中75%肟菌·戊唑醇WG对叶锈病的持效期最长;3个药剂的处理分别较对照增产20.43%、19.21%和15.75%。[结论]75%肟菌·戊唑醇WG、43%戊唑醇SC和12.5%烯唑醇WP可以在生产上用来防治小麦叶锈病。
[Objective] The research aimed to select effective prevention and cure agents for wheat leaf rust. [Method] Six fungicides were sprayed once at wheat jointing stage and again at wheat heading stage 10 days later. [Result] After 20 days of the second spray, the control effects of 75% oxime / tebuconazole WG, 43% tebuconazole SC and 12.5% diniconazole WP on wheat leaf rust were all over 99.00%. After 30 days The control effects were 98.62%, 96.11% and 91.05%, respectively. Among them, 75% of WGD had the longest shelf-life of leaf rust. The three treatments increased yield by 20.43%, 19.21% and 15.75% . [Conclusion] 75% tenfloxacin and tebuconazole WG, 43% tebuconazole SC and 12.5% diniconazole WP were used in the production to control wheat leaf rust.
