摘　　要：对4种药剂进行了防治小麦赤霉病的田间试验。结果表明：小麦初花期用药1次，50%多·酮WP 1050～3150 g/hm2、25%氰烯菌酯SC 1500～3000 mL/hm2及25%戊唑醇EW 1200 mL/hm2防效均超过70%，明显高于25%戊唑醇EW其它处理和25%咪鲜胺EC防效；小麦初花期和盛花期各用药1次，防效进一步提高，50%多·酮WP 和25%氰烯菌酯SC各处理防效均在88%以上，与25%咪鲜胺EC、25%戊唑醇EW药剂处理间差异极显著。在赤霉病流行年份，50%多·酮WP、25%氰烯菌酯SC是防治小麦赤霉病的有效药剂。Four kinds of fungicides were used to control wheat scab disease in the field. The results of experiment indicated that when the fungicides were sprayed in wheat early bloom stage, the efficacies of carbendazim ＋ triadimefon 50% WP 1 050-3 150 g/hm2, JS399-19 25%SC 1 500-3 000 mL/hm2 and tebuconazole 25%EW 1 200 mL/hm2 were above 70%, and were significantly better than other treatments of tebuconazole 25%EW or prochloraz 25%EC. When the fungicides were sprayed both in wheat early bloom and full-bloom stage, the control effects improved further. The control effects of carbendazim＋triadimefon 50%WP and JS399-19 25%SC were all above 88%. Carbendazim＋triadimefon 50%WP and JS399-19 25%SC could control wheat scab disease effectively in epidemic years.
