Whether farmers' behavior of using pesticides reasonable or not directly determines the level of quality and safety of agricultural products. The farmers' behavior of using pesticides was analyzed, and the quantitative analysis of the factors influencing the farmers' behavior was conducted by using the survey data obtained in export-oriented vegetable region. The results indicated that farmer characteristics (such as age, education and whether plan to expand planting acreage), the environment for agricultural production, and farmer's enthusiasm for production have significant effects on farmers' behavior of using pesticides. On this basis, the suggestions were proposed, such as strengthening the propaganda of the pesticide safety use, improving farmers' safety awareness, intensifying guidance and training for farmers, and accelerating the development of rural specialized cooperative economic organizations.
