我国生物源农药应用现状及对策探讨

生物源农药来源于自然界，具有易分解、低残留、低污染、对人畜无害，同时药效期长、特异性强、不易产生抗性等诸多优点。但是由于其药效发挥缓慢、不易保存、使用技术要求高、成本高、作用谱窄等特点，加之农民朋友对其认知不足，生物源农药在市场上的推广难度很大。本文对生物源农药生产应用上存在的问题进行详细分析，并根据具体问题提出相应的解决策略。

The Present Application Situation and the Countermeasures of Biological Pesticides in China

Biological pesticide is derived from nature which can be decomposed easily. So it is of low residue, low pollution, and harmless to human and animal. What＆#39;s more, its effective period is long with strong specificity, not likely to produce resistance. But it has some shortcomings：efficacy is slow, difficult to save, technical requirements is high for users, high cost, narrow spectrum, and lack of cognition from farmers, etc. As a result, the market expansion is very difficult. In this paper, the author analyzed the reasons, and put forward the corresponding solutions.
