摘　　要：探索了多菌灵、甲基硫菌灵、戊唑醇·百菌清、申嗪霉素和氰烯菌酯5种杀菌剂对小麦赤霉病的防治效果以及对小麦的安全性,为小麦赤霉病防治药剂的推广应用提供依据。田间试验参照《农药田间药效试验准则》要求进行,比较了5种药剂对小麦赤霉病的防效。试验5种药剂对小麦赤霉病的防效总体良好,除了40%多菌灵SC和5%申嗪霉素SC低剂量处理的防效略低外,其余试验药剂供试剂量的防效基本在80%以上,其中高剂量70%甲基硫菌灵WP和25%氰烯菌酯SC对小麦赤霉病的防效优良,穗防效和病指防效均达90%以上。This paper investigated the control efficacy of five fungicides including carbendazim, thiophanate-methyl, tebuconazole · chlorothalonil, shenqinmycin and JS399-19 against wheat scab as well as the safety to wheat in order to provide fundamental data for extension of the fungicides. Field trials against wheat scab were carried out according to the guidelines for the field efficacy trials and the control efficacy of different fungicides. The overall control efficacy of the five tested fungicides was good, with most efficacy data above 80%. Among all the tested fungicides, thiophanate-methyl 70% WP and JS399-19 25% SC exhibited excellent control efficacy （〉90%） against wheat scab.
