For the wettable powder, take 1 part, add 200 parts of water, and put it in a glass. Shake well and stand for a certain period of time to observe the suspension. If the drug precipitates slowly, it indicates good suspension. In case of poor quality, silicone additives or 0.10% neutral laundry detergent should be added before use to increase its wetness and spreadability. If the wettable powder absorbs moisture, it should not be used as a spray.
If the powder absorbs agglomerates during storage, it should be placed in a cool, well-ventilated place to dry (not to be exposed to the sun) and crushed before use. If the agglomeration is serious, it can only be used as poisonous soil.
If the emulsion pesticides are not well kept, the following three conditions may occur:
1. Agglomeration phenomenon. If the emulsifiable concentrate has been a non-flowable viscous liquid or has formed a soapy solid, it is proved that the solvent has mostly volatilized and the quality has changed and cannot be used. 2. Precipitation crystallization phenomenon. If the EC cream bottle is immersed in warm water at 30°C to 40°C, the crystals can be dissolved in about 30 minutes to return to a clear liquid, indicating that the quality is good and can be used. If it does not dissolve, it indicates that the quality of the emulsifiable concentrate has changed and cannot be used. 3. Changes in emulsifying properties. Take 1 part of EC, add 200 parts of water, and place it in a glass. Shake well and hold it for about half an hour. If there is no slick in the upper layer, there will be no precipitate in the lower layer and no oil bead in the middle, indicating good emulsifying performance. If there is emulsifiable concentrate on it and there is sedimentation, there will be stratification after 10 minutes, indicating that the emulsion has been destroyed and cannot be used.
