When pesticides are purchased, they must have a certain method of identification. The most important thing is that they are genuine. 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 for reference and hope to help farmers.

1. Emulsion pesticide efficacy identification method

(1) Observing method: It was found that there was precipitation and layered flocculation in the pesticide bottle. The bottle could be placed in hot water and allowed to stand for 1 hour. If the sediment was decomposed and flocculation disappeared, the pesticide was effective. Otherwise, pesticide failure can no longer be made. (2) Swinging method: The stratification phenomenon occurs in the pesticide bottle. The lower layer of the upper slick is precipitated. The vial can be shaken by force to mix the two layers and stand for one hour. If the layer is still stratified, it proves that the pesticide has gone bad. If the stratification disappears, indicating that the pesticide has not failed, it can be used.

2, wettable powder pesticide efficacy identification method

(1) Lightly sprinkle a small amount of pesticide on the ground with splashed water. If the pesticide does not dissolve after 1 minute, it means that it has failed. (2) Dispense 1 gram of pesticide in 1 cup of water and stir it well. If the sedimentation speed is fast and the liquid level is translucent, then the pesticide has become invalid and should not be used.

3, powder system pesticide efficacy method

(1) Suspension method: Take 50 grams of pesticide powder and put it in a glass bottle. Add a little water to make it into a paste. Add appropriate amount of fresh water and mix well. Placed for 10 to 20 minutes, good pesticide particles are fine, and the precipitation is slow and little; failure of the pesticide particles is coarse, precipitation is rapid and many. (2) Observation method: If the powdered pesticide is agglomerated, it is not easily decomposed and proves to be invalid and can no longer be used.
