6％寡糖・链蛋白可湿性粉剂对烟草病毒病的防治效果

摘要

[目的]明确6％寡糖・链蛋白可湿性粉剂对泸州烟区烟草病毒病的防治效果。[方法]在四川省泸州市叙永县麻城乡采用田间试验研究6％寡糖・链蛋白可湿性粉剂1000倍稀释液对烟草病毒病的防治效果。[结果]通过苗期喷施1次，大田期喷施2次6％寡糖・链蛋白可湿性粉剂1000倍稀释液，对烟草病毒病的防治效果达65．44％。[结论]6％寡糖・链蛋白可湿性粉剂可用于防治泸州烟区烟草病毒病。%Objective] The aim was to clarify control effect on tobacco virus diseases of 6% oligosaccharins・ plant activation protein WP in Luzhou.[ Method] The field plot trials were conducted to assess the control efficacy on tobacco virus diseases in Luzhou .[ Result] The control efficacy on tobacco virus diseases were 65.44%, when 1 000-fold diluted of 6% oligosaccharins・ plant activation protein WP was applied dur-ing the period of seeding and field stage.[Conclusions] Tobacco virus diseases could be prevented and controlled effectively by applying 6%oli-gosaccharins・ plant activation protein WP.
