烟草根结线虫化学药剂施用技术研究

Studies on Applied Technology of Chemicals against Tobacco Root-knot Nematode

[目的]探究化学杀线剂的使用技术。[方法]通过盆栽试验和田间试验比较了杀线剂的不同施用方法对烟草根结线虫病的防治效果。[结果]目前常用的化学杀线剂多以触杀型为主,充分与土壤混合是保证化学杀线剂防效的前提。塘施化学杀线剂虽然简单,但防效较差。[结论]研究结果为合理应用化学杀线剂提供了理论依据。

[ Objective ] The aim was to explore the applied technology of chemicals against tobacco root-knot nematode. [ Method ] The con-trol effects of chemical agents to kill tobacco root-knot nematode were compared through pot experiments and field experiments. [ Result] Themost commonly used chemical nematicides mostly tag type based, fully mixed with the soil chemistry was a prerequisite to ensure effective pre-vention nematicides. Centralized administration of chemical nematicides was simple, but poor control effect. [ Conclusion] The results providetheoretical basis for the preferred use of chemical nematicides.
