At present, there are many brands in the pesticide market, and various types of dosage forms are dazzling. For many products, it is difficult for farmers to identify the authenticity. It is difficult to distinguish between wettable powder and emulsion pesticide. Let's take a look at how to identify these two agents.
The wettable powder should be loose powder, no agglomeration, and uniform color. If the powder is agglomerated, the taste of the medicine is changed, or the mixture is squeezed into a group by hand, it indicates that the medicine has failed. It is also possible to take 30 grams of the medicine into the container, add a small amount of water to make a paste, and add 150 grams of water to stir. If the solubility is not good or precipitates quickly, it indicates that the pesticide has deteriorated.
The emulsion should be a homogeneous liquid with no precipitation or suspension. If it is found that the long-term unused bottled emulsion pesticide is turbid, there is sedimentation or suspension flocculation, the bottle can be shaken vigorously. After standing for 1 hour, if the agent does not stratify, it indicates normal, if stratification occurs again, Indicates that the agent has failed. In addition, the medicine bottle can be warmed in warm water for 1 hour. If the sediment dissolves slowly, it indicates that the pesticide has not deteriorated; if the sediment is difficult to dissolve or insolubilize, it means that it has failed. Or take 1 gram of emulsifiable pesticide, add 100 grams of water, stir well and let stand for 1 hour. If there is no emulsifiable oil on the surface of the liquid, there is no sediment at the bottom, and the liquid is milky white, indicating that the agent is good; if there is sediment at the bottom, the water and oil are layered, indicating The medicine has expired.
