Problems solved by technology

However, there is no use for the control of epiparasites in livestock and poultry
Moreover, the existing neem oil preparations are mainly emulsifiable concentrates and water-emulsions. These two preparations either have environmental pollution problems or stratification, and the dosage is relatively large, which has caused adverse consequences to the ecological environment and product quality.

Embodiment 1

[0017] Example 1: Neem Oil Microemulsion Insecticide consists of neem oil, emulsifier, co-emulsion and deionized water. The above neem oil is CO 2 Obtained by supercritical extraction, emulsifier is C 8 ~C 20 Alkylbenzene sulfonate and polyoxyethylene sorbitan fatty acid ester help emulsify n-butanol, n-pentanol, n-hexanol, n-heptanol. The weight percentages of the above components: 0.1% of neem oil, 40% of emulsifier, 15% of co-emulsion agent, and 44.9% of deionized water. When preparing, first stir and mix neem oil with emulsifier and co-emulsifier in proportion, then gradually add a small amount of deionized water, heat and stir at 30-50°C until transparent, and finally add the remaining deionized water and stir well That is to get translucent or transparent neem oil microemulsion.

Embodiment 2

[0018] Example 2: Neem Oil Microemulsion Insecticide consists of neem oil, emulsifier, co-emulsion and deionized water. The above neem oil is CO 2 Obtained by supercritical extraction, emulsifier is C 8 ~C 20 Alkylbenzene sulfonate and polyoxyethylene sorbitan fatty acid ester help emulsify n-butanol, n-pentanol, n-hexanol, n-heptanol. The weight percentages of the above components are: 10% of neem oil, 25% of emulsifier, 5% of co-emulsion agent, and 60% of deionized water. When preparing, first stir and mix neem oil with emulsifier and co-emulsifier in proportion, then gradually add a small amount of deionized water, heat and stir at 30-50°C until transparent, and finally add the remaining deionized water and stir well That is to get translucent or transparent neem oil microemulsion.

Embodiment 3

[0019] Embodiment 3: Neem oil microemulsion insecticide is made up of neem oil, emulsifier, co-emulsion and deionized water, and neem oil is CO 2 Obtained by supercritical extraction, emulsifier is C 8 ~C 18 Alkyl sulfate sodium salt and polyoxyethylene sorbitan fatty acid ester help emulsify n-butanol, n-pentanol, n-hexanol, n-heptanol. The percentage by weight of the above components is 10% of neem oil, 20% of emulsifier, 10% of co-emulsion agent, and 60% of deionized water. When preparing, first stir and mix neem oil with emulsifier and co-emulsifier in proportion, then gradually add a small amount of deionized water, heat and stir at 30-50°C until transparent, and finally add the remaining deionized water and stir well That is to get translucent or transparent neem oil microemulsion.

Abstract

The invention provides neem oil microemulsion and a preparation method thereof which have the advantages of presenting high effect of killing vermin on the body surfaces of animals, overcoming the service durability of chemical drugs, reducing usage amount and drug cost and enhancing the insecticidal activity. The invention also has another purpose of providing the application of the neem oil microemulsion in controlling the verminosis which appears on the body surfaces of the animals. The invention adopts the following technical scheme to realize that seed oil prepared from the insecticidal plant, i.e. neem, is used as an insecticidal active component; and under the action of emulsifier and assistant emulsion, the neem seed oil is uniformly dispersed in deionized water to form the semitransparent or transparent nim oil microemulsion which is of oil-in-water type (O / W type).

Description

technical field [0001] The invention relates to an animal body surface insecticide, in particular to an animal body surface insecticidal active microemulsion containing neem oil and application thereof. Background technique [0002] China is a large breeding country in the world, and every year, huge losses are caused to the breeding industry due to the harm of ectoparasites such as ticks, mites, flies, mosquitoes and fleas. At present, due to the frequent use of chemically synthesized drugs in the prevention and control of animal ectoparasites, problems such as human and animal toxicity, drug residues, drug resistance, and environmental pollution have arisen. For this reason, the development of broad-spectrum, high-efficiency, low-residue plant-derived drugs that are safe for the environment and humans and animals has gradually attracted attention. [0003] Neem is a world-recognized high-efficiency insecticidal plant, and its neem seed oil not only has a variety of biolog...
