Beauveria bassiana belongs to the phylum of fungi, seminiflora, hyphomycetes, trachyta, trachyceae and Beauveria. Beauveria bassiana is one of the insecticidal fungi widely used in pest biological control at home and abroad. It is considered to be the most potential insect pathogenic fungus. The high toxic strain of Beauveria bassiana forms an invasive structure when it grows briefly on the larval wall of Helicoverpa armigera, while the low toxic strain produces slender creeping hyphae on the larval wall. These hyphae will absorb nutrients from the pest and eventually lead to the death of the pest. Beauveria bassiana is a broad-spectrum insecticidal fungus. Researchers at home and abroad use Beauveria bassiana to control agricultural and forestry pests such as corn borer, pine caterpillar, small sugarcane borer, blind toon, grain elephant, citrus red spider and aphid. In particular, the biological control of corn borer and pine caterpillar has been used as a conventional means in China for many years. Beauveria bassiana can effectively control the number of insects without harming other natural enemies and beneficial organisms, which is fully in line with the purpose of comprehensive pest management. At the same time, because it is easy to produce in large quantities and the control cost is competitive, it has a wide application prospect. Beauveria bassiana is a fungal microbial insecticide, and its effective insecticidal substance is the live spore of Beauveria bassiana. After contacting with pests, spores germinate and grow under appropriate conditions. Hyphae invade the insect body and produce a large number of hyphae and secretions, which makes the pests sick and die after about 4-5 days. This product can effectively control insect population, infect and kill pests. Pests are not easy to produce drug resistance, safe for human and livestock and do not pollute the environment. Beauveria bassiana can parasitize more than 700 insects and mites in 15 orders and 149 families, including Lepidoptera, Hymenoptera, Homoptera and Orthoptera. It is mainly used to control pine caterpillar, corn borer, sorghum borer, soybean heartworm, weevil, potato beetle, tea green leaf cicada, rice bract, rice leaf cicada, rice planthopper, etc.
Specific efficacy of Beauveria bassiana:
1.Green, safe and reliable:
Fungal biological insecticides and Beauveria bassiana have no oral toxicity to humans and animals.
2.Unique insecticidal mechanism, no drug resistance:
Beauveria bassiana is a parasitic natural enemy of pests. After contacting pests, it secretes a variety of insect epidermal degrading enzymes, penetrates the body wall of pests, enters the body cavity and reproduces rapidly in insects; At the same time, it secretes a large amount of Beauveria bassiana toxin, destroys the body tissue of pests, and finally makes pests die because they can not maintain normal life activities. Beauveria bassiana is infected to death by contacting with the body wall of pests under natural conditions, and pests will not have any resistance to it. After years of use, the effect is getting better and better.
3. Repeated infection, long-term effect, one-time medication, no insects in the whole season:
The suitable soil environment is especially suitable for the growth and reproduction of Beauveria bassiana. Beauveria bassiana can use the nutrients in the body of pests to reproduce in large numbers, produce a large number of spores and continue to infect other pests.
4. Promote crop growth and increase production and income:
The culture medium in the production and fermentation of Beauveria bassiana is processed as the carrier of the product. The carrier is rich in a large number of amino acids, polypeptide enzymes, trace elements and other nutrients necessary for crop growth, which can promote crop growth and effectively improve crop yield and quality.
