摘要
为了有效降低农药残留,提供葡萄安全生产及质量控制的保障,比较了苦参碱和藜芦碱两种生物农药对哈尔滨地区露地葡萄常见病(霜霉病)虫(绿盲蝽)害的防控效果。结果表明:两种生物农药对葡萄病虫害均有一定的防控效果,与常规化学农药防控相比,使用生物农药能显著降低绿盲蝽对葡萄叶片的危害;但对霜霉病的防控效果没有常规化学农药显著。因此,建议生物农药应与化学农药交替使用于葡萄生产。
In order to reduce the pesticide residue effectively and provide the guarantee of quality control for grape safety production,two biological insecticides against diseases （downy mildew） and pests （Apolygus lucorum） of grape in open field of Harbin area were comparatively analyzed. The results showed that two biological pesticides had different control effects. Compared with the conventional chemical pesticides prevention and control, the biological pesticides could significantly reduce harm for grape leaves; However, the effect on the prevention and control of downy mildew without conventional chemical pesticides was not significant. Biological pesticide and chemical pesticides should be used interchangeably in grape production.
