1. Identify true and false from pesticide labels and packaging
1. Identify from the pesticide label. The pesticide label should indicate the product name, pesticide registration certificate number, product standard number, production license number or production standard certificate number, as well as the active ingredients, content, weight, product performance, toxicity, use, use method, production date, Validity period, stated items and manufacturer name, address, postal code. Where the pesticide is packaged, it shall also indicate the sub-assembly unit and the pesticide packaging registration certificate number.
2. Judging from the name of the pesticide product. The product name on the label should be a Chinese common name or a legal product name. However, the names of pesticide products on the market are very chaotic. Some of them are free to take the name of the product, and some are free to add "Wang, Huang, the most, FH, CP, I, II, compound, high-efficiency, non-toxic, no residue" And so on, these are illegal names. Pesticide purchasers should first carefully check the pesticide label, and products that are not certain that the name of the pesticide contained in the product should not be easily purchased.
3, the same measurement of product specifications should be the same, can not be large or small, internal and external packaging should be complete, can not be damaged.
4. View the product certificate. According to the "Pesticide Management Regulations" and relevant regulations, each product packaging box should be accompanied by a product certificate. The pesticide purchaser can first ask the operator to show the factory certificate to ensure the quality of the purchased product.
5. Bulk pesticide products cannot be purchased. Because production and business operators can be adulterated at any time, it is difficult to deal with problems.
Second, identify the pros and cons from the form of pesticide substances
1, powder, wettable powder should be loose powder, no clumps. If there is agglomeration or more graininess, it means that it has been damp. Not only the fineness of the product will not meet the requirements, but also the content of its active ingredients may change. If the color of the product is uneven, it may indicate a quality problem.
2, the emulsifiable concentrate should be a homogeneous liquid, no sediment or suspended matter, such as stratification and turbidity, or the emulsion after dilution with water is uneven or there are oil slicks and sediments, indicating that the quality of the product may be problematic.
3. Suspending agent and suspoemulsion should be a flowable suspension, no agglomeration, long-term storage, there may be a small amount of stratification, but it should be restored to its original state after shaking. If it is shaken, the product cannot be restored to its original state or still Agglomeration, indicating the quality of the product.
4. If the tablet for fumigation is in powder form, it indicates that it has failed.
5, the water agent should be a homogeneous liquid, no precipitation or suspended matter, generally no turbid precipitation after dilution with water.
6, granule products should be uniform in thickness, should not contain many powders.
