[目的]筛选出防治烟粉虱高工效的施药方式,为烟粉虱的防治提供科学依据。[方法]在京郊温室中,应用热力烟雾机、常规喷雾、静电喷雾、超低容量喷雾和灌根5种施药方式防治番茄上烟粉虱。[结果]应用热力烟雾机施药对烟粉虱可以取得良好的防治效果,在用柴油作稀释剂时,防效在75%以上。应用热雾剂防治烟粉虱,防效在82%以上,减少1/3用药量,防效与常规常量喷雾施药方式比较无显著差异。[结论]热力烟雾机在烟粉虱的田间防治中可大面积推广应用。
[Objective] The study aimed to screen out the high erodibility spraying methods for controlling whitefly and provide a scientific basis for the control of whitefly. [Method] In the greenhouse of Beijing suburbs, the control of Bemisia tabaci on tomato was carried out by means of thermal fogger, conventional spray, electrostatic spray, ultra low volume spray and rooting. [Result] The application of heat smoke machine could get good control effect on Bemisia tabaci. When using diesel as diluent, the control effect was over 75%. Application of hot fog agent to control whiteflies, the control effect of more than 82%, reducing the 1/3 dose, control effect and the conventional constant spray application no significant difference. [Conclusion] The thermal fogger could be popularized widely in the field of whitefly control.
