[目的]明确香叶天竺葵的病虫害种类、危害情况,并探索其主要虫害的防治技术。[方法]2007~2008年在广西主要种植基地对香叶天竺葵的病虫害进行调查并采用随机区组设计进行田间药效试验。[结果]危害香叶天竺葵的虫害有22种,病害有5种。其中主要害虫斜纹夜蛾的发生高峰分别为6月和9月。田间防治试验表明,5%氟铃脲悬浮剂和1%甲维盐微囊悬浮剂对斜纹夜蛾有较高的防效,药后7d防效均大于88.58%,持效期为14d。[结论]该研究可为香叶天竺葵规范化种植中的病虫害防治工作提供有益的支持。
[Objective] The purpose of this study was to clarify the pest and disease types of Geranium spp., And to explore the prevention and treatment techniques of its major pests. [Method] The pests and diseases of Geranium spp. From 2007 to 2008 were surveyed in the main planting bases in Guangxi and the randomized block design was used to conduct field efficacy tests. [Result] There were 22 kinds of insect pests endangering Geranium spp. And 5 kinds of diseases. The main pest occurrence Spodoptera litura was June and September respectively. Field control tests showed that 5% hexaflumuron suspension and 1% carvedilol microcapsule suspension had higher control effect on Spodoptera litura, the control effect was more than 88.58% on the 7th day and the persistence period was 14 days. [Conclusion] This research could provide useful support for pest control in the standardized planting of geranium.
