苹果主要病虫害全程生物农药防控效果

Effect of Full-scale Biological Pesticide Control on Major Diseases and Pests of Apples

文章旨在研究全程使用生物农药对苹果主要病虫害的防控效果。将50×667 m^(2)的苹果园平均分为生物农药防控区、化学农药防控区和空白对照区,比较不同防控手段对苹果斑点落叶病和苹果小叶卷蛾的防治效果。经过研究与对比,发现生物农药防控区的病虫害防治效果与化学农药的病虫害防治效果基本相同,而生物农药防控的危害更低,值得大范围推广应用。

The paper studies the prevention and control effects of biopesticides on major pests and diseases of apples throughout the whole process.A 50×667 m^(2) apple orchard was divided into a biological pesticide control zone,a chemical pesticide control zone and a blank control zone on average.The control effects of different prevention and control methods on apple leaf spot disease and apple leaf roller moth are compared.The pest and disease control effect of biopesticide prevention and control areas is basically the same as that of chemical pesticides,and the harm of biopesticide prevention and control is lower,which is worth promoting and applying.
