At the same time, it has also provided many criminals with opportunities to take advantage of it. At present, there are many phenomena of selling bio-pesticide on the market, so farmers friends are buying. What should you pay attention to when using biological pesticides?
Look at the product packaging specifications
Biological pesticides such as plant sources, mineral sources, microorganisms, proteins and oligosaccharides are generally used in large quantities, with large packaging specifications and packaging specifications within 50 ml (g), and are likely to be counterfeit drugs.
Plant growth regulators (such as brassinolide, indoleacetic acid, etc.) and sexual attractants are used in small amounts, and the packaging size is above 100 ml (g), which is likely to be a counterfeit drug.
Two-view product dosage form
Many biological pesticides can only be made into several fixed dosage forms due to their own characteristics, such as Bacillus thuringiensis products, only wettable powders, suspending agents, water-dispersible granules, and other types of proteins and oligosaccharides. Agent products. Before buying, look at 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.
Three check product scope
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.
Quad core 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.
Five look at the 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.
Six inspection products valid
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.
