The packaging materials used for the regular qualified pesticides are novel, durable, tightly sealed, and the shock-proof material between the bottles is tightly packed. The pesticide registration number, product standard number, production license number (or production permit number), and packaging are printed on the outside of the packaging box. Specifications, signs of toxicity, content of active ingredients, name of the manufacturer, site, etc., affixed with certificate of conformity and instructions for use. The packaging of counterfeit and inferior pesticides is generally rough and inconsistent, and the bottle mouth seals are lax. There are many leakage phenomena, and there are very few certificates or instructions for use. So, how to correctly purchase and identify the authenticity of pesticides? 1. Emulsion pesticides can be identified by oscillation, heating, dilution, odor, etc.: (1) Oscillating method: Observe whether there is delamination in the bottle, if it has been layered, that is, under the slick At this time, the available force is evenly oscillated. If it is still stratified after standing for 1 hour, it means that it is a counterfeit pesticide. (2) Heating method: For the precipitated EC pesticides, even the bottle is placed in hot water, the water temperature is hot, and the precipitated insoluble material is about 1 hour old. (3) Dilution method: For pesticides without stratification and sedimentation, about 10 ml can be taken in a white glass bottle, 30 ml of water is added, and allowed to stand for half an hour after stirring. Qualified pesticides have no slicks on the water surface, no sedimentation on the water bottom, and the diluted solution is milky white. On the contrary, it is a counterfeit pesticide. In addition, it can also be odorized or ignited to identify. Some lawbreakers packed some oil-like stuff into bottles and impersonated pesticides. At this time, they could open the bottle caps and gently smell them with their noses. If no smell of pesticides were detected, they could be judged to be counterfeit pesticides. Some unscrupulous elements added a large amount of organic solvents, such as benzene or kerosene, diesel oil, etc. to qualified pesticides. These pesticides smelled like a kerosene or diesel fuel. When they were used in small amounts, they burned and emitted a lot of black smoke. 2, water pesticides: qualified products without precipitation, diluted into a uniform liquid, no precipitation layering phenomenon. The shoddy products had obvious precipitation, and the diluted liquid was stratified. 3, powder pesticides: qualified product powder fine, smooth, easy to spray from the duster, there is a clear smell, if it is a wettable powder, it can evenly suspended in water. Counterfeit pesticides are generally coarse, not smooth, odor is not strong or odor, poor quality wettable powder is generally difficult to dissolve in water or precipitation after adding water. 4, granules pesticides: generally qualified products uniform particles, there is a strong smell, into the water is not easy to change color. The shoddy products are not uniform in the granules, the odor is not strong, or they tend to change color in water.
