摘要
当前农产品中农药残留量超标问题突出,农业生态环境遭受不同程度的破坏,其中一个重要原因是农药使用技术落后导致农药过量使用。目前生产上广泛采用高容量喷雾技术施药,农药利用率极低,防治效果不尽理想。本文综述了农药雾滴在靶标植物上沉积过程及药液流失原因,以及药剂浓度、雾滴密度、药液表面张力和水中金属离子等因素对农药发挥生物活性的影响,以探寻更精确的农药使用技术和方法。
There is a great waste in pesticide application in China. Some advances in influence of spray volume on pesticide retention on targets and efficacy were reviewed. This review focused on depositing of droplets on targets, and effect of surface tension of the solution and the water quality on pesticide deposition and performance. Also, the relationship of pharmacology efficacy and concentration or droplet density was discussed.
