Abstract
Although scholars have become increasingly concerned about finding ways to encourage more farmers to use biopesticides and fewer to use chemical pesticides, few studies have investigated the prevalence of Chinese rice farmers' mixed use of biopesticides and chemical pesticides for pest management. Based on a household survey in Hubei Province, China, this study found that 59.18% of the sample rice farmers used a mix of biopesticides and chemical pesticides. There is mainly a complementarity relationship between rice farmers' decision to use biopesticides and chemical pesticides. The pursuit of multiple production purposes is the main reason why farmers decide on the mixed-use of pesticides. Specifically, farmers generally tend to use biopesticides to ensure food safety for consumption, and chemical pesticides to reduce costs for profitability. The decision of farmers to mix pesticides has led to an increase of pesticide varieties and costs. However, it reduces the frequency of pesticide use, and does not result in a significant increase in rice yield and output value. While food safety should be emphasized in working towards greater use of biopesticides, rice farmers' mixed use of biopesticides and chemical pesticides will remain for a long time until the biotechnology is more developed. In fact, programs that investigate the effects of a combination of biopesticides and chemical pesticides should be implemented to achieve pesticide reduction, because biopesticides and chemical pesticides have specific disadvantages. © 2022 Society of Chemical Industry.
