Floating method: Take 1 gram of wettable powder pesticide and spread it evenly on 200 ml of clean water. If it is wet within 1 minute and sink into water, it will be no dead pesticide, otherwise it will be failure pesticide. Oscillating method: When the emulsion pesticide appears oil-water separation, it can oscillate by force and shake the bottle. After standing for 1 hour, if the separation layer still appears, it means that the drug has failed. Hot-melting method: Put a deep-seated emulsion pesticide into a bottle of warm water at 50°C. After 1 hour, the precipitate slowly dissolves, indicating that the drug has not failed. If the precipitate is hardly soluble or insoluble, the drug is already metamorphosed. Suspension method: Take 50 grams of wettable powder pesticide, put it into a glass container, add water and stir well. After standing for 10 minutes, if the pesticide has poor solubility, the suspended powder particles are coarse, which means that it is a failure pesticide.
