What are the tricks to judge the authenticity of true and false pesticides?

What are the tricks to judge the authenticity of true and false pesticides? Let me talk about my opinion. First of all, pesticides in agricultural production can greatly promote the growth of various crops, increase crop yield and improve the quality of agricultural products. However, some lawless elements aimed at the pesticide market, making and selling fake products, and made some inferior pesticides with no control effect enter the pesticide market, which not only failed to effectively control crop pests and diseases, but also increased the drug resistance of pests and diseases, and some even caused serious pests and diseases, wasting funds and manpower, resulting in crop yield reduction. In order to avoid being deceived into buying fake pesticides, you should go to a regular agricultural company or chain store when you buy them. Everyone has a business license, so you must take the invoice when you buy it. At the same time, you should check the pesticide packaging label, site, production date, and the most important thing is the product certificate. If the production date of pesticide packaging is the same as the production date of internal standard, it means that this pesticide is a qualified product tested by the national quality inspection department.

Usually there are four kinds of pesticides: powder, granule, suspending agent and emulsifiable concentrate, which can be identified by naked eyes. (wettable powder) Feel loose and even, caked and granular products have been wetted, and the effective components have changed, which will have adverse effects after use. (particles). The particles are uniform in size, loose and dry, and the particles appear powdery, indicating that there is something wrong with the product. (suspension concentrate). It is a suspended liquid. After shaking, the product can not be restored to its original state, or there is precipitation, which indicates that there is something wrong with the product. (EC). The transparent liquid has no precipitation and appears turbid. When the emulsion is diluted with water, floating particles can be seen by naked eyes, indicating that the product has problems. Narrator is observed with the naked eye, don't feel inferior. A simple method to collect expired and deteriorated pesticides. Let me introduce some intuition and judgment skills.

In fact, it is easy to sign the authenticity of pesticides according to the packaging now, and it should be identified from the following aspects. You can see the registration number. Each pesticide variety has its own pesticide registration number. Now our mobile phone can download China Pesticide Information Network. When purchasing pesticides, you can enter the pesticide registration number through the pesticide information network for inquiry. If the registration information is exactly the same, it will generally not be a fake and shoddy product. If the registration information does not match the information on the package (for example, the registered emulsifiable concentrate is microemulsion, or the registered crop is wheat aphid, but there are various crops on the package), it may be a fake and shoddy product.

Scan the QR code. According to the requirements of the national pesticide management regulations, each bottle of pesticide (except foliar fertilizer) has a QR code, which contains all the information of the bottle of pesticide. In fact, to put it bluntly, each bottle of pesticides has its own ID card, and the authenticity of this bottle of pesticides can be found through this QR code. Buy it at a regular pesticide store. In 20 19, all agricultural distributors will be allowed to sell pesticides, and all pesticides must be filed online. Therefore, when buying pesticides, you must go to the regular pesticide sales point and don't buy pesticides from mobile vendors.
