Abstract:

Under different conditions of land fragmentation, it is of great practical significance to clarify the key factors that affect the application of biological pesticides by rice farmers to reduce the amount of pesticides and ensure the quality and safety of agricultural products. Based on 765 field survey questionnaires of farming households in Hubei Province in 2017, a multi-objective utility model of rice farmers’ bio-pesticide application behavior was constructed from the three aspects of risk minimization, profit maximization, and food safety, to empirically test the heterogeneous influence of grain growing objectives on rice farmers’ bio-pesticide application behavior under different land fragmentation conditions. The results show that: first, using the indicator of percentage of grain production for self-consumption, the more likely the products are to meet their own consumption needs, the greater the possibility that farming households would apply biological pesticides. Moreover, the possibility of applying biological pesticides will increase by 10.56% for every 1% increase in the proportion of self-reserved grain ration. Second, for rice farmers with a low degree of land fragmentation (the average plot area is greater than 0.133 hm 2), the purpose of grain growing has a negative impact on the application of biological pesticides, while for rice farmers with a high degree of land fragmentation (the average plot area is less than 0.133 hm 2), the purpose of grain growing shows a positive impact. Third, the application of biological pesticides by rice farmers is also positively affected by the awareness of pesticide residues, the awareness of the importance of green agricultural products, market risk perception and health level, as well as negatively affected by market risk perception. According to the conclusions,we put forward the following policy suggestions: the government should accelerate the construction of farmland standardization to realize homogeneous production, and accelerate the popularization of new agricultural technologies and agricultural development situation, and ensure the quality of agricultural products from both the source of production and market construction.
