6种杀菌剂防治草莓灰霉病的田间药效评价

Evaluation of Control Efficacy of Six Fungicides against Gray Mold Rot of Strawberry

探索了啶酰菌胺、唑醚·氟酰胺、嘧菌环胺、啶氧菌酯、腐霉利、嘧霉胺6种杀菌剂对草莓灰霉病的防治效果及对草莓的安全性,为药剂的推广应用提供依据。试验参照《农药田间药效试验准则》要求,进行了防治草莓灰霉病的田间试验,比较不同药剂对草莓灰霉病的防治效果。田间试验结果显示：啶酰菌胺、唑醚·氟酰胺、嘧菌环胺、啶氧菌酯4种杀菌剂对草莓灰霉病的防治效果达90%,腐霉利、嘧霉胺防治效果为74%~78%。啶酰菌胺、唑醚·氟酰胺、嘧菌环胺、啶氧菌酯4种杀菌剂防效优良,差异不显著。腐霉利、嘧霉胺防治效果较好,但防效不及上述4种杀菌剂。

This study aims to investigate the control efficacy of six fungicides against gray mold rot of strawberry as well as the safety to strawberry in order to provide fundamental data for extension of the fungicides.Field trials against gray mold rot of strawberry were carried out according to the Guidelines for the field efficacy trials and the control efficacy of different fungicides was evaluated.Control efficacy of boscalid,pyraclostrobinfluxapyroxad,cyprodinil,picoxystrobin against gray mold rot of strawberry was about 90%,while the control efficacy of procymidone and pyrimethanil was about74%-78%.Control efficacy of boscalid,pyraclostrobin-fluxapyroxad,cyprodinil,picoxystrobin against gray mold rot of strawberry was excellent,between which the difference was not significant.Procymidone and pyrimethanil also exhibited certain control efficacy,which was significantly lower than 4 fungicides mentioned above.
