近年,烟粉虱已成为我县棚室蔬菜上的主要害虫,该虫繁殖力强,周期短,世代重叠。给防治工作带来了一定的困难,菜农只好加大农药用量,使蔬菜上有农药残留。为提高防治效果,降低蔬菜农药残留和污染,保证绿色无公害蔬菜安全生产,我们选择了环保型生物农药复方蜡蚧轮枝菌防治烟粉虱试验。1试验目的本试验采用生物农药——复方蜡蚧轮枝菌进行防治保护地番茄烟粉虱,为该药在防治棚室蔬菜烟粉虱上大面积推广、合理安全使用农药提供科学依据。
In recent years, Bemisia tabaci has become a major pest on vegetables in our county’s booths. The insects have strong reproductive capacity, short cycle times and overlapping generations. Brought some difficulties to prevention and control work. The vegetable farmer had to increase the amount of pesticide and make the pesticide residues on vegetables. In order to improve the control effect, reduce the pesticide residue and pollution of vegetables and ensure the safe production of green pollution-free vegetables, we selected the biopesticide compound Verticillium lecanii to control Bemisia tabaci. 1 Objectives of the experiment The test biopesticide - Verticillium lecanii compound for control of B. tabaci in the protected areas for the large-scale promotion of the drug in the control of green house beetle whitefly, the scientific basis for the safe and rational use of pesticides.
