Abstract: Combined with the annual dynamic monitoring of Empoasca vitis (Gothe) in tea garden of Fengqing county of Yunnan province, four green prevention and control modes were used to study the prevention and control effect of Empoasca vitis (Gothe) in tea garden, and the cost was calculated. Two times of botanical biological pesticides and one time of chemical pesticides were used to prevent and control the Empoasca vitis (Gothe) in tea garden on June 16, June 24 and July 22, respectively. The results showed that the prevention and control model was pruning + stone sulfur mixture garden sealing+blue board+biological pesticide (450 times dilution of 0.6% rotenone)+chemical pesticide (1 000 times dilution of 6% ethyl doxycycline). Under this mode of control, the average correction control effect of 7 days after three times of treatment were 78.85%, 64.650% and 76.20%, respectively, and which increased by 25.11, 41.63 and 22.68 percentage points compared with conventional control, respectively. Compared with conventional control, the output value increased by 2 100 yuan/hm2, and the ratio of output to investment was 14.6.
