Poor storage or failure of storage of chemical pesticides can cause deterioration or failure of pesticides. The simple identification methods generally include: Identification method of dairy pesticides: Observing method, it is found that there are sedimentation and stratification flocculation in the pesticide. The bottle can be placed in hot water and allowed to stand for 1 hour. If the sediment is decomposed, the flocculent disappears, indicating that the pesticide is effective; Otherwise, it is considered invalid. Shaking method, stratification phenomenon occurs in the pesticide bottle, the lower layer of the upper layer of oil slicks, the medicine bottle can be shaken to make the pesticide uniform, and then allowed to stand for 1 hour. If the layering disappears, it means that it has not expired and can be used continuously. If it is still stratified, it proves that the pesticide has deteriorated. Powder pesticide identification method: observation method, such as powder pesticide has been agglomerated, not easy to break, proved invalid, can no longer be used. Suspension method, take 50 grams of powder pesticide, put it in a glass bottle, add a little water to make a paste, add appropriate amount of water and stir evenly, put it for 10-20 minutes, good pesticide powder is fine, less and the precipitation is slow; Pesticide powders precipitate quickly and often. Cauterization method: Take 10-20 grams of powder pesticide, put it on a metal sheet and put it on fire. If it is white smoke, it proves that the pesticide has not failed, otherwise it means it has failed. Wettable powder pesticide identification method: Take a cup of water and gently sprinkle a little pesticide on the water. After 1 minute, if the pesticide can not be dissolved in the water, it has deteriorated. In addition, 1 g of pesticide is sprinkled into a glass of water and stirred thoroughly. If precipitation occurs quickly, the liquid surface appears translucent, indicating that the pesticide has failed. Identification method of granule pesticide: If the coated granule powder falls off a lot, or the kneaded granules disintegrate the drug granules very much, the powder in the packaging bag is a lot, and it is not granules, indicating that the pesticide has failed.
