When purchasing pesticides, you must master certain methods of identification. The truth is the most important. How can we buy pesticides with good efficacy in the current complex pesticide market? The following methods are simple ways to identify the efficacy of pesticides . The Chinese pesticide network is for reference and hopes to help the farmers. 1. Emulsion pesticide efficacy identification method (1) Observation method: It is found that there is sedimentation and stratified flocculation in the pesticide bottle. The bottle can be placed in hot water and allowed to stand for 1 hour. If the sediment is decomposed and the flocculation disappears, the pesticide is effective. Otherwise, pesticide failure can no longer be achieved. (2) Shaking method: stratification occurs in the pesticide bottle, the lower layer of the upper layer of oil slicks, the medicine bottle can be shaken vigorously, and the two layers are mixed and allowed to stand for 1 hour. If it is still layered, it proves that the pesticide has deteriorated. If the delamination disappears, the pesticide has not expired and can be used. 2, wettable powder pesticide efficacy identification method (1) Lightly sprinkle a small amount of biological pesticide on the ground with water. If the pesticide does not dissolve after 1 minute, it means that it has failed. (2) Sprinkle 1 gram of pesticide into 1 cup of water and mix well. If the sedimentation speed is fast, the liquid surface is translucent, indicating that the pesticide has failed, and the pesticide network is reminded that it should not be used. 3, powder pesticides efficacy identification method (1) Suspension method: Take 50 grams powder pesticide, in a glass bottle, add a little water into a paste, plus the amount of water and mix well. After being placed for 10~20 minutes, the good pesticide powder is fine and the precipitation is slow and less; the pesticide powder is coarse and the precipitation is fast and much. (2) Observation method: If the powder bio-pesticide has agglomerated, it is not easy to decompose, and it proves that it has failed and can no longer be used.
