Problems solved by technology

[0005] The technical problem mainly solved by the present invention: Aiming at the single-dose chemical insecticide commonly used at present, it not only brings chemical agent pollution to the ecological environment, has poor antibacterial properties, but also makes the insecticide resistance of pests continuously strengthened, resulting in increased pesticide residues and poor control effect. The unsatisfactory status quo provides a method for extracting essential oils from pure natural plants to prepare insecticides. The method uses natural plants Polygonum chinensis, Pinellia and Tripterygium wilfordii as raw materials, and prepares essential oils through extraction, and mixes them with camphor ball quicklime Compounded to obtain a pure natural plant source compound insecticide

example 1

[0020] Firstly, take 500g of Polygonum spicosa with a plant height between 40cm, chop it with a guillotine, rinse it with deionized water for 3 times, add distilled water 5 times its volume, put it into a pot and heat it until it boils for 40 minutes, then filter Remove the filter residue, add 100g of soap to the filtrate while it is hot, stir with a stirring bar until the soap dissolves, and store at 40°C; then put 500g of pinellia into a ceramic jar, add an appropriate amount of alum water until it is submerged, and then put it in the microwave In the oscillator, oscillate with microwaves for 8 hours and then filter to get the original juice. Add 200mL Pinellia alum original juice drop by drop into the above-mentioned peppery lye lye through the dropping funnel. ; Then move the mixed solution after standing overnight into a horizontal centrifuge, centrifuge at a high speed of 8000r / min for 20min, separate and remove the filter residue, obtain the supernatant, and set aside; N...

example 2

[0023]Firstly, take 550g of Polygonum spicosa with a plant height between 50cm, chop it with a guillotine, rinse it with deionized water 4 times, add distilled water 5.5 times its volume, put it in a pot and heat it until it boils for 50 minutes, then filter Remove the filter residue, add 135g of soap to the filtrate while it is hot, stir with a stirring bar until the soap dissolves, and store at 45°C; then put 550g of pinellia in a ceramic jar, add an appropriate amount of alum water until it is submerged, and then put it in the microwave In the oscillator, oscillate with microwave for 10 hours and filter to get the raw juice, drop 250mL Pinellia alum raw juice into the above-mentioned peppery lye solution drop by drop through the dropping funnel, control the dropping speed so that the dropwise addition is completed within 15 minutes, and let it stand overnight ; Then move the mixed solution after standing overnight into a horizontal centrifuge, centrifuge at a high speed of 8...

Abstract

The invention discloses a preparation method of a complex insecticide sourced from pure natural plants and belongs to the field of pesticide preparation. The natural plants including willow-leaved smartweed, pinellia ternata and tripterygium wilfordii are taken as raw materials, essential oil is prepared through extraction and compounded with mothballs and quicklime, and the complex insecticide sourced from the pure natural plants is prepared. Instances prove that the prepared complex insecticide eliminates environmental pollution of chemical pesticides, prevents drug resistance of pests, has remarkable control effect, reduces pesticide application cost for farmers and is worth of large-scale popularization and application in agricultural production; finally, the pest control effect is higher than 85%, and the leaf protection rate is higher than 88%.

Description

technical field [0001] The invention discloses a preparation method of a pure natural plant source compound insecticide, belonging to the field of pesticide preparation. Background technique [0002] In agricultural production, in order to ensure the yield and quality of agricultural products, a large number of chemical pesticides are usually sprayed on the farmland on a large scale, which brings chemical pollution to the ecological environment and causes some pests to develop resistance rapidly, so often The practice of further increasing the amount of pesticides is adopted to kill the pests, which has caused the pesticide residues in agricultural products to seriously exceed the standard, and has brought great harm to human food. The development and utilization of pesticide resources with good environmental compatibility and harmlessness to human beings are increasingly favored by the whole country. [0003] In daily life, the number of various single-dose insecticides is...
