Milk pesticide identification method:
Observation method: It was found that there were precipitation and layered flocculation in the pesticide. The vial was placed in hot water and allowed to stand for 1 hour. If the precipitate was decomposed, the flocculent disappeared, indicating that the pesticide was effective; otherwise, it could not be used.
Swinging method: The stratification phenomenon occurs in the pesticide bottle. The lower layer of the upper oil slick is precipitated, and the medicine bottle can be shaken to make the pesticide uniform. Let stand for 1 hour. If it is still stratified, it proves that the deterioration of the pesticide has failed. If the stratification disappears, it means that it has not failed and can continue to be used.

Cauterization method: Take 10-20 grams of powder pesticide, put it on a metal plate and put it on fire. If it is white smoke, it means that the pesticide has not failed. Otherwise, it means that it has failed, and 5% of carbendazim powder is usually identified by this method.
Observing method: If the powdered pesticide has agglomerated, it is not easily broken and proves to be invalid and can no longer be used.
Wettable powder Pesticide identification method: Take a cup of fresh water, and gently sprinkle a little pesticide on the surface of the water. After 1 minute, if the pesticide can not be dissolved in water, it means that it has been degenerated. In addition, 1 gram of pesticide was sprinkled into a glass of water and stirred well. If sedimentation occurred quickly, the liquid surface appeared translucent, indicating that the pesticide had failed and could not be used.
