农药控释剂的研究与应用进展

Progress in research and application of formulations for controlled release of pesticide

在农药使用过程中,由于理化性质不稳定和施药方法不当而造成有效成分易降解或流失,农药控释剂不仅可以保护有效成分免受环境破坏,而且可以减少农药使用剂量和使用次数,有利于生态环境保护,是今后农药剂型发展的重要方向之一。为使农药控释剂不断创新发展,笔者重点综述了当前农药控释剂主要制备方法的研究现状,简单介绍了国内农药控释剂(主要是微胶囊剂)的登记应用和研究开发情况,并分析了农药控释剂研究开发中存在的主要问题,希望控释技术的进一步推广能够为农药的高效、经济和安全使用提供有效途径。

In the process of pesticide use,the active ingredients may be lost or degraded because of unstable physicochemical property and improper application methods.Formulations for controlled release of pesticide not only protect the active ingredient from environmental damage,but also reduce the dosage and frequency of pesticide use and in favor of environmental protection.It is one of the important development directions of pesticide formulations in future.To acquire continuous innovation and development for formulations for controlled release of pesticide,the current research status for the main preparation methods was summarized,the domestic situation of registration,research and development（mainly pesticides microcapsules）in China were briefly introduced,and the main presence problems of the research and development were analyzed too.We hope the further promotion of controlled release technology can provide more effective way for the efficient,economic and safe use of pesticides.
