Analysis Of Economic Factors Affecting Pesticide Application

Pesticide is an important production material in agriculture, which has tremendously contributed to reducing crop loss, solving mankind food problems. However, because of its irrational and large application, pesticide has brought such ignorant effects as air pollution, environmental destroy, food safety and so on, which has baffled agricultural sustainable development. So taking example of Fujian providence this paper analyzed factors aimed to provide scientific basis for resolution.For the close relationship of pesticide contamination and Gross Domestic Products, it was discussed and the alternative models firstly Then, The data of pesticide contamination and GDP from 1980 to 2003 in Fujian province was used to estimate the numerical model. The results suggested that the existent relationship was a mixed curve of "EXPONENT -S" and When GDP achieved 67.41 billion yuan, and that the amplitude of pesticide contamination begun to decline. Pesticide application of Fujian province would rise lowly unless pest broke out during the visible period in future, and the application would not be more than 6.55 ten thousand ton per year.In order to research the effecting factors on pesticide application, was used to weigh pesticide application. Firstly, the possible economic factors were designed, which included traditional crops planting areas, economic crops planting areas, other crop planting areas, farmers' pure income per capita, GDP, labor force in countries and the scale of elementary education. Then data of every country from 2001 to 2003 was analyzed by SPSS to ensure the significance of affecting factors. A equation was achieved that was as followed: Y — 488.291 JJMJ. The results showed that the more economic crops were planted, the more money of pesticide was consumed, and every one hectare of economic crops were added, the pesticide expense was add up to 488.291yuan.In this paper, the pesticide application intensity was represented by pesticide expense per unit area which was also analyzed to research the significant factors by SPSS, and the possible factors that included the proponent of traditional crops and economic crops, farmers' pure income per capita, GDP per capita, cultivated area per capita and elementary educational ratio were designed. The equation that was Y = 79.189 JJMJB showed that the proponent of economic crops was significant, and the larger proponent of economic crops was, the more pesticide per hectare were expensed.The reasons that other factors were not significant were explained in this paper.Eventually, some suggestions for rational utilization of pesticide of Fujian Province were put forward in this paper. Those were as follows. 1) developing the areas of economic plants and increasing its industrialization. 2) Reinforcing the basic education should be used to improve farmer's educational level, and to help farmers to acquire information. 3) Enhancing the plant protection stations in counties, and improving technology extension and service system. 3) Perfecting the system and mechanism of pesticide management, adoping the HACCP system of the primary products and market access systems should be included.
