Product name
Bacillus thuringiensis (B) is in English Abbreviation of name.
Physical and chemical properties The active ingredient companion crystal is composed of three major types of proteins with a molecular weight of 10,000 Daltons and has the physical and chemical properties of proteins. Spores, another active component of B, are living bacteria. Under suitable conditions, they can germinate, grow, and reproduce.
Pesticide mechanism: When B is swallowed by pests, the companion crystals of B are dissolved by alkaline intestinal fluid in the midgut and hydrolyzed by protease into active toxins, causing The epithelial cells of the midgut swell and become perforated, and spores, another active component of B, invade the hemocoel and multiply in large numbers, causing the pests to suffer from sepsis and die.
Toxicity: low toxicity to humans and livestock, low toxicity to poultry, birds, fish, livestock, etc., no harm to natural enemies of pests.
The control object has a good poisoning effect on Lepidoptera, Diptera, Coleoptera and other pests as well as animal and plant nematodes. According to domestic and foreign application statistics, B shows high toxicity to forest pests, fruit tree pests, and tea tree pests. The most commonly used control targets with special effects are: cabbage caterpillar, diamondback moth, Spodoptera litura, corn borer, rice bractworm, rice leaf roller, stem borer, stem borer, cotton bollworm, cotton bridging bug, tea borer Caterpillars, tea loopers, pine caterpillars, canopy caterpillars, poisonous moths, and thorny moths. In addition, it is also effective in controlling underground nematodes in soybean seed dressing.
Usage: For the larvae of lepidopteran, dipteran, and coleopteran pests, you can use/microliter of suspension agent M mixed with 1 catties of water (multiple times) spray. In order to expand the insecticidal spectrum and enhance the rapid effect of B, neutral pesticides with high efficiency, low residue and easy decomposition can also be added for mixed application if necessary. Precautions: B must be used when the temperature is above ℃, and should be applied in the evening to achieve its best insecticidal effect. It is highly toxic to silkworms and castor silkworms and cannot be used near mulberry orchards or sericulture sites.
Cannot be mixed with fungicides and should be stored in a cool, dry place away from light.
