6种防治烟草花叶病的药剂筛选

Screening of the Six Pesticides Controlling the Tobacco Mosaic Disease

[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。

[ 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 to- bacco 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. Tbe better effect control can get by using 20% moroxydine · cupric acetate wettable powder, 0.5% lentinan agent, 6% alkene · bluestone wettable powder, and 2% oligosacchar/ns 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 tobac- co mosaic in production should alternately use the 20% moroxydine · cupric acetate wettable powder, 0.5% lentinan agent, 6% alkene ~ bluestone wettable powder, and 2% olizosaccharins agent nesticides in Pu＇ er City.
