摘　　要：通过田间药效试验,对比4种新型杀菌剂防治烟草赤星病的效果。结果表明,240 g/L氯氟醚菌唑·吡唑醚菌酯乳油、42.4%氟唑菌酰胺·吡唑醚菌酯悬浮剂、400 g/L氯氟醚菌唑·吡唑醚菌酯悬浮剂、38%吡唑醚菌酯·啶酰菌胺水分散粒剂等4种药剂防效均高于40%菌核净可湿性粉剂,其中400 g/L氯氟醚菌唑·吡唑醚菌酯悬浮剂的防效最好,可达85.60%。为避免烟叶农残超标,可选用以上4种药剂交替使用防治烟草赤星病。The efficacy of four new fungicides against tobacco brown spot was compared by field efficacy test.The results showed that the control effect of 240 g/L clofluconazole·pyraclostrobin EC,42.4%fluconazole*pyraclostrobin SC,400 g/L clofluconazole·pyraclostrobin SC,38%pyraclostrobin•picrylamide WG were higher than that of 40%sclerotin WP,and 400 g/L clofluconazole·pyraclostrobin SC has the best control effect,reached 85.60%.In order to avoid excessive pesticide residue in tobacco leaf,the above 4 kinds of fungicides can be used alternately to prevent and control tobacco brown spot.
