农药在运输、保管、使用过程中,由于种种原因,商标常有破损或脱落,以致无法确定农药的种类,造成积压、浪费,有些地方甚至还发生过误用农药,出现药害等事故。为了对这些无商标农药进行准确的鉴别,经过多次反复的试验和研究,搞出了一套常用液体(水、乳剂)和粉剂农药的鉴別方法。使用这种方法鉴别农药,所用试剂不多,方法亦比较简便。 Due to various reasons, pesticides are often damaged or shed during transportation, storage and use. As a result, the types of pesticides can not be identified, resulting in backlog and waste. In some places pesticide misuse has even occurred, causing injury and other accidents. In order to accurately identify these non-trademark pesticides, after many repeated tests and studies, came up with a set of common liquid (water, emulsion) and powder pesticides identification method. Use this method to identify pesticides, the use of reagents is small, the method is also relatively simple.
