上世纪90年代以来,随着复配品种的普及和国家政策的放开,我国的农药制剂得到了极快发展,但随之而来的环境压力使农药残留成为突出的问题,影响到食品安全和农产品出口。为此国家农药政策再次调整,针对高毒、高残留农药的限产、停产等环境保护和资源节约政策不断出台,引起高效农药的开发和耕作制度的变革。这一变革使得农药制剂向缓释化、低溶剂化、水基化、颗粒化的方向发展成为一种必然趋势。缓释型农药,优势独特,其各种剂型都得到不同程度的应用,如微囊悬浮剂、片剂、泡腾片剂、颗粒剂等。其中,微囊悬浮 Since the 90s of the last century, with the popularization of compound varieties and the liberalization of national policies, the pesticide formulations in our country have witnessed rapid development. However, the ensuing environmental pressure has made pesticide residues a prominent issue affecting food safety And agricultural exports. For this reason, the national pesticide policy is readjusted once again. In response to the continuous introduction of policies on environmental protection and resource conservation aimed at limiting the production of high-toxic and high-residue pesticides and stopping production, the development of highly efficient pesticides and the reform of the farming system have been brought about. This change makes the pesticide formulations to slow release, low solvation, water-based, granulation direction has become an inevitable trend. Sustained-release pesticides, the unique advantages of its various formulations have been different levels of application, such as microcapsule suspensions, tablets, effervescent tablets, granules and so on. Among them, the microcapsule suspension
