6种防治烟草花叶病的药剂筛选

目的]对防治烟草花叶病的部分药剂进行筛选,为生产上选择防治花叶病的药剂提供依据。方法]在普洱市6个县区进行了6种药剂对烟草花叶病的防治效果试验。结果]各种药剂对防治烟草花叶病均有一定效果。在6个县区,20%吗胍.乙酸铜可湿性粉剂、0.5%香菇多糖水剂、6%烯羟.硫酸铜可湿性粉剂、2%氨基寡糖素水剂的防治效果均较好,平均防治效果分别达60.3%、58.3%、57.6%和57.5%。24%混脂.硫酸铜水乳剂的防治效果较差,防治效果仅55.1%。结论]在普洱市烟叶生产上进行烟草花叶病的防治可采用20%吗胍.乙酸铜可湿性粉剂、0.5%香菇多糖水剂、6%烯羟.硫酸铜可湿性粉剂、2%氨基寡糖素水剂交替轮换使用。

Screening of the Six Pesticides Controlling the Tobacco Mosaic Disease

Objective] The basis of the prevention and control of tobacco mosaic disease in the tobacco production was provided through the experiment in the selection of 6 pesticides controlling the disease.Method]An experiment in the control efficiency of 6 pesticides against tobacco mosaic disease of flue-cured tobacco was carried out.Result] The results showed that a variety of pesticides had a certain effect on the control of tobacco mosaic disease.The better effect control can get by using 20% moroxydine·cupric acetate wettable powder,0.5% lentinan agent,6% alkene·bluestone wettable powder,and 2% oligosaccharins agent with average controlling effect as 60.3%,58.3%,57.6% and 57.5%,respectively.24% mixed fatty bluestone had relatively poor controlling effect as only 55.1%.Conclusion] The controlling of tobacco mosaic in production should alternately use the 20% moroxydine·cupric acetate wettable powder,0.5% lentinan agent,6% alkene·bluestone wettable powder,and 2% oligosaccharins agent pesticides in Pu'er City.
