摘要
为明确小麦白粉病防治适期,并筛选出有效防治药剂,2016年进行了不同用药时间、不同用药次数、不同药剂防治小麦白粉病的田间试验。试验结果表明:小麦白粉病防治适期在白粉病发病初期,用药越早,防效越高。2次用药防效明显高于防治1次。供试药剂中30%醚菌酯SC的防效最好,在2次施药情况下,病叶率防效与病指防效分别为74.67%与89.11%。
To determine the optimum application timing of wheat powdery mildew, and screen out effective fungicides, three kinds of trials were carried out in 2016. The results showed that the optimum control stage of wheat powdery mildew was in the early stage of disease. Kresoxim-methyl 30% SC had better control effect than other fungicides used in the trial, the control effects of diseased leave and disease index reached 74.67% and 89.11%, respectively.
