Due to the complexity of the pesticide brand, many farmers have no choice, how to judge the true and false pesticides? Here are two ways to do this:
The first method is to identify the authenticity of the pesticide from the appearance of the label and the package. The pesticide label must indicate the product name, product registration number, product standard number, production license number, and the composition, content, toxicity, use method, date of manufacture, expiration date, precautions, and name, address, and postal code of the manufacturer. For the distribution of pesticides, the sub-assembly unit should also be indicated. In addition, also pay attention to check whether the product has a factory certificate. Do not buy pesticide products that do not have a factory certificate and bulk.
The second method is to identify the pros and cons of the pesticide substance form. If the powder or wettable powder has agglomeration or more particles, it indicates that it has been damp; if the color of the product is not uniform, there may be quality problems; emulsification and turbidity may occur, or the emulsion after dilution with water may be uneven or Oil slicks and sediments indicate that the quality of the product may be problematic; suspending agents and suspoemulsions should be a flowable, non-caking suspension. There may be a small amount of stratification during long-term storage, but after shaking, the product cannot be restored to its original state or There are still agglomerations, indicating that product quality may be problematic. After the water agent is diluted with water, turbid precipitation generally does not occur. Granule products should be uniform in thickness and should not contain many powders.
