Abstract: In order to reduce the application of chemical pesticides in the production of flowering Chinese cabbage, from 2019 to 2021, technologies of chemical, physical, mechanical, biological and agricultural prevention and control were integrated in the demonstration bases of Nansha district and Zengcheng district of Guangzhou, including soil retting, selection of resistant cultivars, yellow board + sex attractant compound prevention and control, light inducement control, natural enemy insect prevention and control, "push-pull" prevention and control, biological pesticide prevention and control, chemical pesticide prevention and control. And demonstration of technology was conducted. The core demonstration area was 210 hm2 , and the radiation area was more than 2 000 hm2 . While effectively controlling flowering Chinese cabbage pests, the application of chemical pesticides decreased by 26.3% and the yield of cabbage increased by 4.76%.
