First, the burning method This method is used to identify powder pesticides. Take appropriate powder pesticides on metal objects and burn them on fire. If white smoke is observed, pesticides will not fail. Second, the shock method This method is used to identify emulsion pesticides. According to the characteristics of easy separation of emulsion pesticides, first look at whether it is stratified, if it is not stratified, the pesticide is effective; if it is stratified, it can oscillate up and down several times to make it uniform, and then stand for 40-60 minutes, then carefully Observe that if you stratify again, it means that the pesticide has failed and you cannot use it. Third, the dissolution method This method is used to identify precipitated emulsion pesticides. The vials were soaked in water at 40°C-60°C for about 60 minutes. If the bottom of the bottle dissolves, it means that the pesticide has not failed. If the precipitate does not dissolve, the precipitate can be filtered out, take a small amount and add appropriate amount of warm water, if the precipitate dissolves, indicating that the pesticide can still be used. Fourth, watering method This method is used to identify powder, wettable powder and emulsion pesticides. If it is a powder, it is advisable to take 50 grams of the medicine into a glass and add appropriate amount of fresh water. Stir it to dissolve it. Allow to stand for about 30 minutes. If the particles are evenly suspended and there is no sediment at the bottom of the bottle, the pesticide has not failed. The wettable powders are easy to agglomerate when stored, and the agglomerates can be powdered first and a small amount of fresh water can be added. If dissolved quickly, it means that the pesticide is effective, otherwise it cannot be used. If it is an emulsion, take a small amount into a glass, add an appropriate amount of water to stir, and let stand for 30 minutes. If there is no oil on the surface of the water, there is no sediment at the bottom of the cup, indicating that the pesticide is effective.
