摘要
调查了2005～2007年衡阳地区衡南县、耒阳市烤烟主要虫害的发生情况,对虫害的发展趋势进行了分析,并针对每种虫害提出了主要的防治措施,得出烟叶生产过程中需要进行科学地预测预报,将病虫害控制在萌芽状态,对于已有的病虫害要提高化学防治水平,通过以化学施药为主,结合物理和生物措施防治,尽量减少农药的使用次数和残留,生产无公害烟叶的结论。对今后衡阳地区烤烟的生产和田间管理具有一定参考作用。
The occurrence situations of main insect pests of tobacco in Hengnan County and Leiyang County of Hengyang Area from 2005 to 2007 were investigated, and the developing trends of insect pests were analyzed, then some main control measures aimed at each insect pest were proposed. The results indicated that in order to produce nonpolluted tobacco leaves, during the production process of tobacco leaves, it need scientific forecast to control the diseases and insect pests at germination stage; for those occurred diseases and insect pests should enhance chemical control level that need combining chemical treatment with physical and biological treatments to reduce the applying times and residues of pesticide as possible as they can.
