Problems solved by technology

However, the disadvantage of this patent is that the recombinant polyhedrosis virus expressing insect neurotoxin is not a wild strain, but an artificial strain transformed by genetic engineering technology in the laboratory. The strains have certain toxicity to humans and animals, and usually the recombined strains are genetically unstable and are likely to mutate, further causing potential uncontrollable risks
At the same time, the patented technology CN200810008516.5 does not provide a detailed process for preparing the suspension, and the dosage form of the pesticide is crucial to the efficacy of the pesticide

Abstract

The invention discloses a virus pesticide suspending agent containing spinosad. The virus pesticide suspending agent is prepared from the following components in percentage by weight: 0.1%-20% of spinosad, 1%-10% of a dispersing agent, 1%-7% of an antifreezing agent, 0.2%-10% of a stabilizer, 0.1%-5% of a synergist, 0.5%-2% of an ultraviolet protecting agent, 0.1%-2% of an antifoaming agent, 0.1%-3% of a pH modifier and the balance of water; the prepared suspending agent also absorbs an insect virus; the insect virus is one or combination of two of a nuclear polyhedrosis virus and a granulosis virus NPV; the content of an insect virus inclusion body in the suspending agent is 5-20,000,000,000 PIB / ml; and the spinosad is one or a mixture of two of spinosad and ethyl spinosad. The spinosad and a virus pesticide disclosed by the invention are compounded, so that the problem of insect resistance can be solved, and the virus pesticide suspending agent is environment-friendly and safe.

Description

technical field [0001] The invention relates to the technical field of pesticide production, in particular to a virus insecticidal suspension containing spinosad. Background technique [0002] At present, people have used chemical pesticides for a long time, and pests are prone to develop resistance, and the use of a large amount of pesticides has caused great damage to food safety and the ecological environment, and a large amount of chemical pesticides is also likely to cause human and animal poisoning. [0003] Environmental pressure makes people more and more hope that there will be green and efficient pesticides to replace the existing toxic chemical pesticides. [0004] In the existing pesticide technology, there is a class of spinosad insecticides in the existing pesticide technology, wherein spinosad includes spinosad and ethyl spinosad. Although spinosad is non-toxic to humans and animals, it comes from The metabolites of natural actinomycetes fermentation are fr...
