First of all, fake and inferior pesticides can be identified through labels. There are many pesticides nowadays, and they all have manufacturers, contact numbers, storage conditions, production licenses, implementation standards, capacities, precautions and warning labels. If we find incomplete labels when purchasing pesticides, then we should pay attention at this time, because according to the "Measures for the Management of Pesticide Labels and Instructions" it is clearly stipulated that pesticide production must contain the above information on the label. Generally speaking, products that do not exist are not allowed to leave the factory, that is, products that do not comply with regulations and standards.
Check whether the pesticide label has a production date and shelf life. Generally speaking, when buying pesticides, they will have a production date and a shelf life. If the pesticides we buy do not have such a shelf life, or even have a far different shelf life than pesticides of the same condition, we should pay attention at this time. After all, the efficacy and ingredients of pesticides are similar, but the formulas are different. If one pesticide has a shelf life of one year, but another can be stored for more than 7 years, then you should pay attention to the fact that the difference is often too big. It could be a bad pesticide.
When you buy pesticides, they usually come in packaging. Look on the outer packaging to see if there is a certificate of conformity. Just like when we buy a car, there will be a certificate. If the pesticide we buy does not have a certificate, we should pay attention to this. All pesticides that have passed the product self-inspection will have a certificate. If the pesticide you purchase does not have a certification, it is very likely that it does not have a production license, so you should pay attention to this.
Looking at the color can also help you identify fake pesticides. Usually when we buy pesticides, we more or less observe the color of the pesticides. Sometimes there is an unpleasant smell. But if we buy some pesticides and find that the colors are wrong and the smell is abnormal, then we should also cause it at this time. Note that if there is an obvious difference, it may be a fake pesticide.
