摘　　要：为筛选出散叶莴苣灰霉病防治药剂,本文进行了10%多抗霉素可湿性粉剂、45%异菌腺悬浮剂、20%丁子香酚水乳剂、50%啜酰菌胺水分散粒剂不同浓度对散叶莴苣的田间药效试验。结果表明,于莴苣灰霉病发生初期连续防治2次,药后7、14d45%异菌腺悬浮剂、50%喘酰菌胺水分散粒剂效果表现优越,最终病指防效均达80%以上,且对莴苣生长安全,无残留。Several fungicides were tested to determine the control effect against loose-headed gray mold, including Polyxins 10% WP, Rovral 45% SC, Eugeno 20% EW and Boscalid 50% WG. The result showed that Rovral 45% SC and Boscalid 50% WG could control the disease effectively when spraying twice at the beginning of the loose -headed gray mold , with the effect of disease index of more than 80%. Both fungicides were found to be safe for the crop and no residue.
