摘要
化学农药的使用带来了致使人畜直接中毒、环境污染等许多问题。由于长期使用某些化学农药,使害虫产生了抗药性。针对化学农药的种种弊端,国内外已研制出一系列选择性强、效率高、成本低、不污染环境、对人畜无害的生物衣药。广义的生物农药包括微生物农药(细菌、真菌、病毒)以及生物工程植物两大类。当前生物农药的开发和使用仍处于起步阶段,但其发展前景十分美好。
Application of chemical agricultural chemicals will cause a number of problems of tending to directly poison person and livestock, to pollute environment, and so on. Also, long application will enable injurious insects to get drug-resistant. In order to solve these problems, a series of high quality agricultural chemicals have been developed at home and abroad, all characteristic of strong selectivity, high efficiency, low cost, no pollution and harmlessness to person and livestock. Biologic agricultural chemicals in a broad sense should consist of two main types, micro organic agricultural chemicals (involving bacterium, fungus and virus) and bioengineering plants. Although development and application of biologic agricultural chemicals is still in its beginning stages today, the prospects of development will be magnificent.
