In production practice, farmers' friends sometimes find that the use of pesticides is not effective. This may be caused by the use of pesticides that are not properly used or the purchase of counterfeit pesticides. How to buy pesticides? Here are five questions that farmers should pay attention to when choosing pesticides: First, pay attention to whether the business operators are legitimate and legal. Regular managers are familiar with the relevant knowledge, formal purchasing channels, quality is not guaranteed, and they can accurately and accurately describe pest control. , counterpart pesticides and their characteristics, use of technology, prevention and control period. Second, pay attention to whether the pesticide packaging is qualified. The qualified pesticides are packed tightly, the contents of the labels are complete, the "three certificates" are complete, and the pesticide registration certificate, production approval permit, and standard certificate number are clearly written. Third, we must pay attention to the external quality of pesticides, qualified pesticide emulsion without layering precipitation, powder bulk does not agglomerate, granules particles evenly attached, suspension agent clear and thorough, shake quickly. Fourth, pay attention to the date of production: the general period of validity of pesticides is two years, more than the effective period of reduced efficacy. Fifth, pay attention to whether the price is appropriate. Some pesticides prices are obviously low, and the same pesticide price is half the difference, which is obviously impossible. Therefore, we must beware of pesticides with a false pesticide or insufficient content of active ingredients.
