中药材桔梗的病虫害防治技术
作者:管理员    发布于:2017-12-27 05:56:28    文字:【】【】【

一、桔梗的主要病害有轮纹病和斑枯病,两种病的发生均与种植密度过大、高温多湿有关。在夏季高温、高湿易发病季节,应加强田间排水,降低田间湿度以减轻发病。发病初期用1∶1∶100的波尔多液、65%代森锌600倍液、50%多菌灵、退菌特1000倍液或50%甲基硫菌灵1000倍液喷施,10——15天1次,连续2——3次。


二、桔梗的虫害主要有蚜虫和小地老虎。
1、蚜虫可喷施50%敌敌畏1000——1500倍液或40%乐果1500——2000倍液或5%杀螟硫磷1000——2000倍液进行防治,7——10天1次,连喷2——3次。
2、小地老虎为害时,每亩用50%辛硫磷250——300毫升,拌湿润细土15千克做成毒土;或用90%敌百虫晶体250克加适量水拌炒香的棉籽饼5千克做成毒饵,于傍晚顺行撒施于根际进行防治。
