Abstract: In recent years, due to the influence of varieties, climate, field cultivation management and other factors, the occurrence of diseases and pests in eggplant has been increasing. Especially, the continuous occurrence of bacterial wilt, anthrax, fusarium wilt and other major diseases caused serious losses, and poses a threat to the safety of eggplant production. In this study, an experiment was conducted to estimate the natural loss rate of eggplant pests and diseases in Chongqing Hechuan vegetable planting base from 2020 to 2021, and the contribution rate of plant protection technology after adopting comprehensive control measures was discussed.The results of this research showed that the control efficiency of bacterial wilt, anthracnose, fusarium wilt, whitefly, aphid and red spider ineggplant increased by 29.97%, 24.22%, 27.50%, 11.39%, 10.85% and 11.13% respectively. The results provide an effective basis for controlling the outbreak of eggplant bacterial wilt and other diseases and ensuring the stable and high yield of eggplant.
