First, the product registration number. China has implemented a pesticide registration system. All pesticides produced, processed, distributed and sold in China are covered by pesticide registration management. Pesticides can be produced, sold and used after registration. Do not buy pesticides that do not have a registration number on the label when purchasing pesticides.
Second, the product is valid. China stipulates that general pesticides should have a two-year validity period, that is, the content of active ingredients and main indicators within two years after leaving the factory meet the quality standards. Do not purchase pesticides that are longer than the expiration date or that are not marked for expiration.
Third, do not buy damaged pesticides.
Fourth, do not buy pesticides with incomplete or unclear labels.
5. Judging the pros and cons of the appearance of pesticide products. Powders and wettable powders may be damp if they are agglomerated. Not only the fineness is not required, but the active ingredient content also changes. If there is more graininess, generally the fineness does not meet the requirements; if the color is uneven, there may be quality problems.
If the emulsifiable concentrate is turbid and crystallized, and the crystallization does not disappear after being exposed to the normal temperature for a period of time, it indicates that there is a certain quality problem. Unevenness of the emulsion after emulsification of the emulsifiable concentrate with water or oil slick, sediment, and eucalyptus indicate quality problems. If there is agglomeration after the suspension of the plastic suspension, there is a quality problem. If the tablet for fumigation is in powder form, it indicates that it has failed.
Sixth, quality inspection. If the quality of the pesticide is suspected, the most accurate and reliable method is to send the pesticide sample to the local pesticide testing center for inspection according to the quality standard.
