摘要
选取清除田间病残体、杀菌剂和清除病残体与杀菌剂相结合的方法进行草莓白粉病田间药效试验。试验结果表明,3种杀菌剂对草莓白粉病具有不同程度的防效,清除田间病残体结合施用3种杀菌剂的防治效果显著高于单独施用杀菌剂,且试验浓度条件下无药害产生,对防治草莓白粉病有重要作用。清除病残结合施用30%氟菌唑和15%三唑酮见效快且药效持续性好,防治效果较好,建议生产中以上2种药剂交替轮换使用防治草莓白粉病。
The field efficacy tests of strawberry powdery mildew were carried out by using the methods of removing disease residues,fungicides and the combination of removing disease residues and fungicides.The results showed that the three fungicides had different degrees of control effects on strawberry powdery mildew.The control effects of removing field disease residues combined with the application of three fungicides were significantly higher than those of single fungicides,and there was no phytotoxicity under the experimental concentration conditions,which played an important role in the control of strawberry powdery mildew.30% fludioxonil and 15% triadimefon in combination with removing disease residues had quick and continuous effects,and the control effects were beeter.It was suggested that the above two fungicides should be used alternately to control strawberry powdery mildew in production.
