Because it is harmful for biological efficiency, and of non-target organisms there was no danger for human, on the environment pollution-free, can effectively reduce the pesticide residue, for agricultural product quality safety guarantee, reduce the pollution to the environment, so he was widely admired by governments and favor. In the worlds chemical pesticide consumption drops year by year, biological pesticide double-digit growth rate of rapid growth. This article is based on the summary of biological pesticide, on the basis of analysis of the development of biological pesticide, this paper probes into various problems, digging biological pesticide, and further research prospects and Suggestions of the development of biological pesticide. Key words:Biological pesticide；Current situation of the development; Prospects for development 1、生物农药概述
