Abstract: Pesticide pollution seriously threatens food safety and the environment of the production area. Paying attention to the choice of pesticide application by farmers is conducive to promoting the reduction of pesticides and green development of agriculture. Based on the field survey data of key tea areas in Shaanxi, Sichuan, Zhejiang and Anhui provinces, the Ordered Probit model was established to study the neighborhood effect and the acquisition of external technology and the adjustment of empirical capital based on the application of neighboring drug application information. Considering that there may be endogenous problems in the perception of pesticide utility, extended ordered probit estimates were also made using instrumental variables. The results are as follows. (1) The information transmission of neighboring pesticide application significantly promotes the increase of pesticide application rate by farmers, indicating that there is a neighborhood effect in the selection of pesticide application by farmers; (2) In the acquisition of external technology, the acquisition of enterprise application technology and the government application of pesticide technology have significantly promoted the reduction of farmer's application, but the regulation effect is not significant; (3) In the empirical capital, the record of pest and disease prevention significantly promotes the reduction of pesticide application by farmers, and the planting period significantly promotes the increase of pesticide application by farmers, but the regulation effect is not significant. Therefore, the government should cultivate the neighborhood information transmission mechanism to “degenerate the disadvantages into profits” through the village science and technology demonstration households, and drive other farmers to reduce the amount of application; at the same time, supplement the necessary technical training and special projects.
