雷公藤叶部病虫害的发生现状、成因及对策

Current infesting situation,reasons and controlling strategies of pests and diseases attacking Tripterygium wilfordii

随着栽培面积、规模的扩大和病虫害管理水平的滞后,地道性中药材雷公藤目前正遭受病虫害的严重危害。2009、2010年对福建省泰宁县雷公藤病虫害进行调查表明,雷公藤叶部病虫害主要表现为危害种类不断增加,复合危害现象普遍,不同藤龄、不同生境的雷公藤上发生水平也各不相同。防治观念淡薄,生产措施不当,管理水平偏低,病虫害的危害潜能较大以及气候异常等是导致叶部病虫害成灾的主要因素。因此,应在边防治边研究的基础上,逐步建立健全预测预报体系,采取有效的无公害病虫害防治技术,确保雷公藤产业的健康发展。

With increasing area and scale of cultivation and hysteresis of management level, Tripterygium wilfordii, one of typical and traditional Chinese medicine plants, were infested by their pests and diseases seriously. The current infesting situation was summed up based on investigation carried out in Taining County, Fujian Province from 2008 to 2010, the results showed that there were more and more pests and diseases which could infest the same plant simultaneously and seriously, and T. wilfordii on different woodlands or with different years had different infesting levels. There were several reasons which led to disasters of pests and disea- ses in forest of T. wilfordii, not only including low control awareness and management level and improper production measures, hut also characteristics of pests and diseases and abnormal climate. In order to ensure development of T. wilfordii industry healthily, the basic research on their pests and diseases must be strengthened as soon as possible, and system of prediction to them also be set up step .by step, and some effective measures free of pollution and residue must be adopted to control these pests and diseases.
