How to identify the authenticity of buying agricultural products
In recent years, the agricultural product market has become more and more abundant. To purchase quality-assured and reliable agricultural products is a matter of great concern to rural consumers, but poor-quality agricultural products are often mixed into the market to make rural consumers difficult to distinguish. Pseudo, the following introduction may be helpful to farmers, and it is convenient for farmers to pay attention to identification when purchasing. Look at the trademark: The pesticides produced by the regular manufacturers should have the trademark registration certificate of the local industry and commerce bureau, the pesticide registration number of the Ministry of Agriculture, and the certificate of approval for the approval of production. Counterfeiters often lack these serial numbers or incomplete serial numbers; their trademarks and usage instructions are clearly printed, formalized, and clearly defined. The trademarks and descriptions of counterfeit pesticides are illegible and incomplete; genuine pesticides are marked with a clear production date and batch number and expiration date. Counterfeit products are often intentionally obscured by labeling or labeling their active ingredients and content, and the type of formulation, as well as their use, poisoning and rescue measures. The labeling of counterfeit pesticides is not detailed enough and complete; true pesticides are printed on the label with manufacturer's name, address, telephone number, zip code and other factory-specific information. The counterfeit and inferior products are usually marked incompletely or with a certain degree of randomness. A little verification can confirm their authenticity. Look at the packaging: True pesticide packaging is regular, strong, and intact, with no leakage. The packaging of domestically-made pesticides generally has the above-mentioned contents. The import of pesticides is more elaborate and generally has detailed descriptions in foreign languages. The packaging of counterfeit and inferior pesticides is not standardized and the content of the labeling is incomplete. See real traits: Emulsion pesticides: Generally there should be no stratification or sedimentation phenomenon, liquid medicine is uniform, clear and transparent; if there is precipitation, it indicates poor quality or fake and inferior products. Powder pesticides: powdery particles are uniform, no agglomeration, strong smell; pesticide particles are not uniform, there is moisture absorption and dampness phenomenon, drug taste is light or can not smell pesticide. Test emulsifying performance: Take a small amount of water in the container, and if the white floc gradually spreads after the dripping water is detected, the emulsion solution will naturally dissolve and emulsify. It is a genuine pesticide, otherwise it is a fake product. Combustion test: The use of inferior organic solvents is often used for counterfeit pesticides. The solvent ignition point is low, burning with fire, and emitting heavy smoke. Genuine pesticides generally do not have this phenomenon. Efficacy test: Take a small amount of the object to be identified in the cap or on the vessel and try to catch a live pest. If the system is fast-acting lethal pesticide, the pest will die immediately. If the pest does not die, it means it is a fake pesticide. When purchasing feeds, the following methods should be combined and comprehensively identified to ensure the quality of the purchased feed. -Look. Observe the feed particle size, shape, and color. In the case of industrial formulated feeds, it is necessary to see whether the raw materials are mixed uniformly, whether the color is uniform, and whether there is mixed foreign matter. - Sniff. Use the nose to identify whether the feed has irritating or spoiling smell. If you need further inspection, you can take a small amount of sample, add appropriate amount of water and mix evenly, so that the smell is fully distributed, so as to identify whether there is odor or odor, high-quality feed generally has a grease smell or a slight fishy smell without musty or odor. -touch. Grab the feed by hand to determine its quality and moisture content. For packing feed, if there is no loose feeling, it means that the feed is stored for too long or has been damp; for bulk feed, you can grab a handful of feed and squeeze it tightly to relax. If the feed is not loose, indicating that the moisture content is too high, Storage is easy to mold deterioration, put your hand into the feed, such as the phenomenon of fever, it indicates that the feed has begun to mold, should not be purchased. -listen. When some feedstuffs are agitated, they may sound similar to metal vibrations or crisper sounds to indicate that the feed is dry. If the water content is high, the sound will not be heard. - dumping. The fresh and dry feed is loose, non-agglomerated, and has good fluidity. When the feed is poured out from the packaging bag, if it has a sticky feeling, it is not easy to flow or has agglomerate phenomenon, indicating that the feed has become mildewed and is not to be purchased.
