First, pay attention to the label. The label should have the name of the pesticide, the name of the commodity and the common name, the pesticide registration certificate, the pesticide production license and the production approval document number, the product standard number, the product performance and precautions, the active ingredients, the content, the dosage form and the net weight (capacity); Name, address, phone number, zip code, etc.
Second, pay attention to the validity period. Generally for two years, there are no fake pesticides that indicate the validity period.
Third, the label is incomplete or unclear, and the pesticides with damaged packaging should not be purchased.
4. Judging the pros and cons of the appearance of pesticides:
1. Powder: If the wettable powder has agglomeration, it is often wet, not only the fineness does not meet the requirements, but also the active ingredient content often changes. If the powder has a lot of graininess, generally the fineness does not meet the requirements.
2. If the cream is stratified and turbid, it may have deteriorated. Unevenness of the emulsion after emulsification of the emulsifiable concentrate with water or oil slick, oil or sediment indicates a quality problem. If the emulsifiable concentrate is crystallized, it will be crystallized at room temperature for a while.
3. After the suspension of the pesticide pesticide, if there is agglomeration, there is a quality problem.
4. If the tablet containing the pesticide component is smoked, it indicates that it has failed.
Fifth, quality inspection. If the quality of the pesticide is suspected to be problematic, the most accurate and reliable method is to send the pesticide sample to the provincial pesticide identification office for inspection.
6. Pesticides with unclear reasons and relatively low market prices are generally counterfeit and inferior pesticides.
