In order to improve farmers' ability to quickly identify fake and inferior pesticides, five simple methods for identifying fake and inferior pesticides are introduced.
1, view method
Liquid pesticides should generally be transparent and free of oil slicks and no sedimentation. A drop of water is quickly emulsified into a milky liquid. The powdered pesticide should be loose and not agglomerated. The wettable powder is shaken into water and becomes an emulsion. . At the same time, it is necessary to check whether the product packaging is qualified, whether there is a product registration number, a production permit number, a security mark, whether the product is within the warranty period.
2. The watering method is suitable for checking emulsion pesticides. Take a little medicine during the inspection, add water 1-2 times, stir and let stand for 1 hour. If there is a floating oil layer on the water surface, the pesticide is a fake pesticide.
3. Oscillating method is used for emulsion pesticides. If the pesticide in the vial is stratified, it can be shaken evenly. After standing for 1 hour, observe that if there is still stratification, the pesticide has deteriorated.
4. Suspension method is used to check wettable powder pesticides. Take a small amount of powder in the cup during the inspection, add appropriate amount of water and stir into a paste, then add water and stir for a period of time. If there is precipitation, it is a fake pesticide.
5. The test method is used to inspect new pesticides. The liquid medicine can be configured according to the instructions for use, and then sprayed on the crops with existing pests and diseases. If the control effect does not meet the control requirements, it indicates that the pesticide is invalid and may be a fake and shoddy pesticide.
