缓释剂能控制有效成分的释放速度、位置和时间,减少有效成分的挥发和流失,延长持效期,减少施药次数,同时还减少或避免农药对环境生态的不良影响;所以以缓释剂型为典型代表的农药剂型科学化是助力农药用量零增长目标的一个重要途径……在今年2月份,农业部提出2020年实现农药用量零增长的目标,并通过了实现这一目标的行动方案。那么如何减少农药用量呢?众所周知,提高农药利用率是关键因素之一。由于存在着乱用药、过量或重复喷施、传统喷雾器械 The slow release agent can control the release speed, location and time of the active ingredient, reduce the volatilization and loss of the active ingredient, prolong the holding time and reduce the application times, and reduce or avoid the adverse effect of the pesticide on the environment and ecology. Therefore, Scientifically formulated pesticide formulations, which are typical representatives, are an important way to help achieve zero growth in pesticide use ... In February this year, the Ministry of Agriculture set forth the goal of zero growth in pesticide consumption by 2020 and adopted a plan of action to achieve this goal. So how to reduce the amount of pesticide it? As we all know, improve pesticide utilization is one of the key factors. Due to the presence of drug abuse, excessive or repeated spraying, the traditional spray equipment
