摘　　要：为探求对小麦赤霉病防效好且对镰刀菌毒素控制较好的药剂,笔者用7种杀菌剂,分别在穗期开展防治1遍和2遍试验。结果表明,用25%氰烯菌酯SC 1800 mL/hm^(2)、600 g/L戊唑·百菌清SC 600 g/hm^(2)、50%叶菌唑WDG 240 g/hm^(2)、48%丙硫菌唑SC 600 mL/hm^(2)防治2遍,对小麦赤霉病和DON(脱氧雪腐镰刀菌烯)、ZEN(玉米赤霉烯酮)毒素的控制均能达到较好的效果。In order to explore the fungicide with good control effect on wheat scab and fusarium toxins,we selected 7 kinds of fungicides on this experiment,and sprayed once and twice at the wheat heading stage.The results showed that application of 25% phenamacril SC 1800 mL/hm^(2),600 g/L tebuconazole-chlorothalonil SC 600 g/hm^(2),50% metconazole WDG 240 g/hm^(2) and 48% prothioconazole SC 600 mL/hm^(2) twice had the best control effects against wheat scab and DON,ZEN toxin.
