辣椒白粉病防治技术初探

Preliminary study of Hot Pepper Powdery Mildew Control

采用引进新农药拿敌稳75%WG(水分散粒剂)开展其不同浓度防治辣椒白粉病试验,探讨辣椒白粉病最佳防治技术。试验结果表明:拿敌稳75%WG3000倍液防治辣椒白粉病,防效达95.27%;增产效果最明显,其平均株高、鲜株重、百果干重、每株总果数、单产、商品率均高于其它处理和当地对照药剂;经济效益比为1∶13.41。

A new fungicide Nativo75%WG at different concentrations was used to control hot pepper powdery mildew in this study.The results showed that the Notivo 75%WG at the 1∶3000 concentration had the best effect on the powdery mildew control up to 95.27%; this treatment significantly increased fruit yield, plant height,fresh plant weight, dry hundred-fruit weight, total fruit number per plant, per-unit-area yield and commodity rate which were higher or more than those of other treatments; and its economic profit ratio is 1∶13.41.
