“…Actually, the damage control model has been widely used in recent decades to study marginal productivity of pesticides in rice, cotton and vegetable production, which all further suggested that pesticides are over-utilized [15][16][17]. For example, Huang et al, in their analysis of rice farming in China, suggested that, on the one hand, pesticides contribute significantly to increase rice production; on the other hand, the marginal contribution of pesticides decline considerably with increasing use of pesticides and approached zero at current average pesticide use level by the rice farmers [15].…”

Understanding the extent of pesticide overuse and what drives rice farmers to overuse pesticide in agricultural production theoretically and empirically is imperative to increase farmers' income, promote agricultural transformation and agricultural sustainable development. In this paper, we examined the phenomenon and pattern of pesticides overuse based on the data collected from 861 rice farmers in Jiangsu and Anhui, two provinces in China. By applying the Cobb-Douglas production function (C-D production function) and the damage control model, we estimated the marginal productivity of pesticides. We also adopted the Binary Probit model to further explore factors leading to overuse of pesticide among farmers. Our findings suggested that the marginal productivity of pesticides is close to zero, indicating that there is an excessive use of pesticides in the surveyed areas. According to the Binary Probit model, we also discovered that female farmers, farmers with knowledge about pesticide toxicity, pesticide residue and farmers who hold the view that massive use of pesticide is inimical to the environment, and farmers who participate in pesticide training organized by the government, are more likely to overuse pesticide. On the contrary, experienced farmers have a lower chance of overusing pesticides. Possible explanations to the above findings may be that applying pesticides in accordance with the instructions causes overusing and farmers who are loss-averse, in order to avoid the risk of income loss that may be caused by disease and insect pests, and keep its own income stable, will still increase the amount of pesticide application. It also indicates that farmers are insensitive to increased pesticide overuse.

“…The primary benefit of transgenic cotton over conventional cotton in China has been reduced insecticide use. As a result of greater protection against bollworm damage with transgenic cotton 47-75 percent less kilograms of insecticide, or 4-13 fewer insecticide applications, were needed to control these pests, reductions in insecticide use associated with transgenic cotton have varied regionally, and in regions where bollworms are not the primary cotton pests, farmers growing transgenic cotton observed a decrease in their insecticide use as low as 14 percent (Huang et al, 2002c). Therefore, farmers in regions with few bollworms may not benefit as much from adopting transgenic cotton as farmers in areas where bollworm are key pest.…”

Purpose -The purpose of this paper is to provide an overview of the current state of knowledge on the economic performance of genetically modified (GM) cotton worldwide based on a wide range of data and source from available literature, and second to assess yield gain and economic performance. Design/methodology/approach -A systematic review was captured to provide the evidence of potential benefits of GM cotton. A country-specific analysis was conducted in order to compare economic indicators and employed meta-analysis to find out the significance of the different of GM cotton over its counterpart.Findings -This paper depicts positive impact of commercialized GM cotton in terms of net revenue, and the benefits, especially in terms of increased yields, are greatest for the mostly farmers in developing countries who have benefitted from the spill over of technology targeted at farmers in industrialized countries.Research limitations/implications -Due to the variability of the data which came from different methodologies, it is difficult to determine the differences of the performances each individual study.Practical implications -This, it is believed that results from this study can be useful for operations of all sizes as the authors think about what needs to be focussed on for long-term producers survival. Originality/value -The paper clearly indicates that China is the highest cotton yield of GM cotton, the lowest cost of GM seed and the lowest cost of chemical spray compare to any other countries. Therefore, this is the fact that the adoption of GM cotton has been widely spread among the farmers across the regions in China. Keywords Agriculture, Benefits, Effects, Cotton growers Paper type General review IntroductionThe benefits of genetically modified (GM) cotton continue to be disputed, despite rapid and widespread adoption since their commercial introduction in the USA in 1995 and first planted in 1996 ( James, 2009). Since its 1996 debut on US cotton farms, according to James (2012) biotech cotton reached 24.3 million hectares in 2012 down from the 24.7 million hectares grown in 2011. With lower global price ...
