How to identify inferior pesticides?

Nowadays, more and more pesticides are sold, and inferior pesticides are also mixed into the market. Pseudo-inferior pesticides often cause serious losses to agricultural production. So, how to identify inferior pesticides?

How to identify inferior pesticides? Identify true and false from the appearance of pesticide labels and packaging:

1. Label: When registering pesticides, there are strict requirements for pesticide labels. The pesticide label should indicate the product name, pesticide registration number, product standard number, production license number or production approval certificate number, and the active ingredients of the pesticide. Content, weight, product performance, toxicity, use, method of use, date of manufacture, expiration date, precautions, name of the manufacturer, address, postal code, and pesticides should also be included in the sub-package unit. In the absence of any of the above, questions about product quality should be questioned.

2. Name: The product name on the label should be a Chinese common name or a legal product name.

3. Specifications: The product specifications of the same metering should be the same, not large or small, the inner and outer packaging should be complete, and there should be no damage.

4, the factory certificate.

5. Bulk pesticide products cannot be purchased.

How to identify inferior pesticides? Identify the pros and cons of the pesticide form:

1, powder, wettable powder should be loose powder, no clumps. If there is agglomeration or more graininess, it means that it has been damp, not only the fineness of the product is not up to the requirement, but also the content of the active ingredient of the term may change. If the color of the product is uneven, it may indicate a quality problem.

2. The emulsifiable concentrate should be a homogeneous liquid with no precipitation or suspended matter. If stratification and turbidity occur, or if the emulsion diluted with water is not uniform or has oil slick or sediment, it may indicate that the quality of the product may be problematic.

3. Suspending agent and suspoemulsion should be a flowable suspension, no agglomeration, long-term storage, there may be a small amount of stratification, but it should be restored to its original state after shaking. If the product does not return to its original shape or remains agglomerated after shaking, there is a quality problem with the product.
