How do biopesticides distinguish true and false?

See product packaging specifications

Plant sources, mineral sources, microorganisms, proteins and oligo-saccharides generally larger amount of bio-pesticides, if Packing in 50 ml (g) or less, it is likely to be counterfeit. Plant growth regulators (such as brassinolide, indoleacetic acid, etc.) and sex attractants are used in small amounts, and the packaging size is above 100 ml (g), which is likely to be a counterfeit drug.

Product dosage form

Many biological pesticides can only be made into several fixed dosage forms because of their own characteristics. For example, only the wettable powder, suspending agent and water-dispersible granules are available in the products of Bacillus thuringiensis. The main products are water-based products such as protein and oligosaccharides. . Before buying, pay attention to the dosage form indicated on the label. For bagged pesticides, touch them by hand, carefully observe the appearance of the product, and observe the state of the product diluted with water if necessary. If the water product becomes a milky white liquid after watering, it may be a fake pesticide.

Check the scope of application

Biological pesticides such as viruses and sexual attractants generally work only for one pest. If the pesticide is indicated for multiple uses, the product may be false.

Nuclear product labeling usage

The use of biological pesticides such as plant sources, mineral sources, microorganisms, proteins and oligosaccharides is relatively large, and the dilution factor is generally less than 500 times. If the product indicates that the dosage per acre is in the range of tens of milliliters (grams), or the dilution factor is more than 1000 times, the product may be false.

See product efficacy statement

Biological pesticides such as plant sources, mineral sources, microorganisms, proteins and oligosaccharides are slower. If the nominal effect is rapid and quick-acting, the product may be fake.

Validation period of product

The active ingredient of the microbial drug is a living organism, which is not resistant to storage, and the shelf life is generally from six months to one year. If such products are marked for a period of two years, the product may be false.
