摘要
生物技术在现代农药研究中的应用日益广泛。通过基因工程技术构建微生物农药菌株可以提高毒力,拓宽杀虫谱。具有抗病、抗虫和抗除草剂性能的转基因作物已投入商业化生产。依据农药新靶标的发现可以进行农药分子设计,开发高效低毒农药。仿生农药的生物合成不仅避免了化学合成的污染,而且为生物农药的制备开辟了新途径。利用微生物和酶降解法可以治理农药残留。依据酶抑制原理设计的试纸法、比色法和传感器法已用于农药残留的快速检测。
The biotechnology is widely used in modern pesticides. The strains of microbe-pesticides reconstructed by genetic engineering can increase toxicity and expand specificity. The transgenic plants with diseaseresistance, insect-resistance and herbicide-resistance have been used for commercial production. According to the new target of pesticides, molecular design for developing new pesticides with high efficiency and low toxicity can be carried out. Biosyntheses of bionics pesticide not only avoid the pollution of chemical synthesis, but also provide a new method for preparing biopesticides. The pesticide residues can be degraded by microbe and enzyme. The methods such as rapid test strip, colorimetry and enzyme biosensor developed according to the principle of enzyme-inhabitation have been used for rapid determination of pesticide residues.
