The damage of counterfeit biological pesticides is well known. Is there any way to identify fake and inferior pesticides? Industry experts pointed out: Accurately determine the true and false, fake and inferior of a pesticide product, usually need to go through the statutory pesticide quality testing unit, according to the various technical indicators and testing methods specified in the product standards. However, when farmers buy pesticides, they can also make preliminary identification through the following simple methods.
(1) According to the label identification: the qualified label should include the main name of the product name, production date, pesticide manufacturer name, address, and contact method. Incomplete or unclear label products are doubtful.
(2) According to the packaging identification: Generally speaking, it is in line with the national regulations on pesticide packaging. Intuitively, packaging, trademarks, product specifications, and factory inspection certificates are all new. If the packaging materials are found to be stale and poorly sealed, There are problems such as damage or packaging, and the quality is doubtful.
(3) According to some characteristics of the appearance: different pesticides have different characteristics, different shapes and colors are different. Powder or wettable powder, should be fluffy powder, no clumps, uniform color. If the powder is agglomerated, the taste of the drug is not strong or there is a mildew and acid odor, indicating that the quality of the drug may change and affect the use effect. Bottled emulsifiable pesticides , if found turbid, stratified or have sediments, flocs, etc., indicate that there may be problems with the quality of the pesticide; if the suspension is found to have serious agglomeration, it may indicate that the quality may be problematic.
