The Xiaobian of China Pesticide Network summarizes the “ knowledge of distinguishing the quality of pesticides †for you.
Regarding the quality of pesticides, we mainly start from the following points:
First, look at the packaging of pesticides in general, in line with the national regulations on pesticide packaging. Intuitively, packaging, trademarks, product specifications, and factory inspection certificates are all new. If the materials used for packaging are found to be stale, the seal is not good, or Damage or packaging has problems such as large and small, and its quality is questionable.
Second, look at the appearance of different characteristics of pesticides have different characteristics, shape and color are different from the different dosage forms. Powder or wettable powder should be loose powder, no clumps and uniform color. If the powder is agglomerated, the taste of the medicine is not strong or there is a mildew and acid odor, indicating that the quality of the medicine may change, affecting the use effect. Bottled emulsifiable pesticides, if found turbid, stratified or have sediments, flocs, etc., indicate that the quality of the pesticide may be problematic; if the suspension is found to have serious agglomeration, it may indicate that the quality may be problematic.
Third, look at the label of the pesticide label qualified should include the variety name, production date, manufacturer name, address, contact information and other main content. A defective or unclear label product is doubtful.
