摘要： 旨在为筛选有效防治韭菜灰霉病的杀菌剂和指导田间科学用药提供参考。2010—2012年，选取6种具有代表性的化学药剂和3种生物药剂展开了连续3年的田间药效试验。试验结果表明，50%多菌灵可湿性粉剂、50%腐霉利可湿性粉剂、40%嘧霉胺悬浮剂、75%百菌清可湿性粉剂、10%苯醚甲环唑水分散粒剂、25%啶菌噁唑乳油、10%多抗霉素可湿性粉剂、0.5%小檗碱水剂和106个孢子/g寡雄腐霉可湿性粉剂对韭菜灰霉病的防治效果分别为69.09%、63.36%~67.62%、64.90%~76.41%、72.62%、54.32%~ 72.61%、82.14%~84.72%、22.04%、38.07%和12.15%。多菌灵、嘧霉胺、百菌清、腐霉利和苯醚甲环唑对韭菜灰霉病的防治效果一般；啶菌噁唑防效较高并且稳定，3年的防效均在80%以上；3种生防药剂具有一定的防治效果。

Abstract: The aim of this study was conducted to provide reference for the screening of novel fungicides and their scientific application in fields. 2010-2012, 6 experimental fungicides and 3 bio-control agents were selected to conduct field efficacy trials used to control Chinese chives gray mold in fields in 3 consecutive years. The results showed that, the control effect of carbendazim 50% WP, procymidone 50% WP, pyrimethanil 40% SC, chlorothalonil 75% WP, difenoconazole 10% WDG, SYP-Z048 25% EC, polyoxin 10% WP, berberine 0.5% and pythium oligadrum 106 spores/g WP were respectively 69.09% , 63.36%-67.62% , 64.90%-76.41% , 72.62% , 54.32%-72.61% , 82.14%-84.72% , 22.04% , 38.07%和12.15% . Carbendazim 50% WP, procymidone 50% WP, pyrimethanil 40% SC, chlorothalonil 75% WP and difenoconazole 10% WDG exhibited common efficacy in Chinese chives gray mold management, while SYP-Z048 25% EC had a safety and steady efficacy with a control effect of more than 80%. 3 bio-control agents also performed certain effect.
