Problems solved by technology

Organophosphorus, pyrethroids, benzoylureas and biochemical pesticides have been compounded and combined to reduce the original toxicity to a certain extent, but due to the results of years of use, the insects have become resistant to pesticides and resistant to pesticides. The properties of the medicine are strengthened year by year, and the effect of alternate use is not very satisfactory

Embodiment 1

[0021] The insecticide of the present invention is prepared by using the following raw materials in weight proportions: 30 parts of Pulsatilla chinensis, 80 parts of Lustonia, 10 parts of Tripterygium wilfordii, 10 parts of chamaejasma, 25 parts of comfrey, 10 parts of Perrin, 5 parts of polysorbate, 5 parts of methyl sulfoxide, 2 parts of turpentine, 2 parts of ethanol, 1 part of argonic acid and 100 parts of demineralized water. Among them, the raw materials of Pulsatilla chinensis, Luniancao, Tripterygium wilfordii, chamaejasma, comfrey, and Peilan are all made of dry raw materials.

[0022] The specific preparation method is as follows:

[0023] (1) Divide the demineralized water into demineralized water A and demineralized water B according to the mass ratio of 5:2; dissolve polysorbate, dimethyl sulfoxide, turpentine, and arboric acid in more than one part in sequence under constant stirring. part of demineralized water A to form a mixture;

[0024] (2) Add ethanol to ...

Embodiment 2

[0031] The insecticide of the present invention is prepared by using the following raw materials in weight proportions: 50 parts of Pulsatilla chinensis, 100 parts of Deer's Grass, 20 parts of Tripterygium wilfordii, 20 parts of chamaejasma, 40 parts of comfrey, 20 parts of Perrin, 10 parts of polysorbate, 10 parts of methyl sulfoxide, 5 parts of turpentine, 5 parts of ethanol, 2 parts of argonic acid and 200 parts of demineralized water.

[0032] A preparation method of an insecticide, comprising the following steps:

[0033] (1) Divide the demineralized water into demineralized water A and demineralized water B according to the mass ratio of 3:2; take the polysorbate, dimethyl sulfoxide, turpentine, and arachidic acid and dissolve them in sequence under continuous stirring. One more part of demineralized water A to form a mixture;

[0034] (2) Add ethanol to the mixture in step (1), and stir well until uniform;

[0035] (3) Use clean water to decoct comfrey 5 times, each t...

Embodiment 3

[0041] The insecticide of the present invention is prepared by using the following raw materials in weight proportions: 45 parts of Pulsatilla chinensis, 85 parts of Lustonia, 13 parts of Tripterygium wilfordii, 15 parts of chamaejasma, 28 parts of comfrey, 12 parts of Perrin, 8 parts of polysorbate, 7 parts of methyl sulfoxide, 4 parts of turpentine, 4 parts of ethanol, 1 part of argonic acid and 145 parts of demineralized water.

[0042] The preparation method is as in Example 2.

[0043] Comparing the prepared insecticide with 2.5% dichlorpyr EC proved that the insecticide of the present invention was 800, 1200, 1800 times diluted, and the control efficiency was 100%, 99%, 98% respectively after 3 days of spraying the green vegetables. ; And 2.5% 1,600-fold diluted medicament anti-efficiency of 1,600-fold dichloride EC is only about 70%. After 10 days, the insecticide 800, 1200, 1800 times dilution of the present invention has an anti-efficiency of 96%; while the anti-effi...

Abstract

The invention discloses an environment-friendly insecticide and a preparation method and application thereof. The insecticide is prepared from, by weight, 30-50 parts of the root of Chinese pulsatilla, 80-100 parts of pyrola, 10-20 parts of thunder god vine, 10-20 parts of radix euphorbiae lantu, 25-40 parts of radix arnebiae seu lithospermi, 10-20 parts of eupatorium, 5-10 parts of polysorbate, 5-10 parts of dimethyl sulfoxide, 2-5 parts of turpentine, 2-5 parts of ethyl alcohol, 1-2 parts of sorbic acid and 100-200 parts of softened water. The insecticide is free of pollution, safe and obvious in deinsectization effect.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an environment-friendly insecticide. Background technique [0002] Today, when advocating green and protecting the environment, many highly toxic and high residue chemicals have been limited or discontinued. Organophosphorus, pyrethroids, benzoylureas, and biochemical pesticides have been compounded and combined to reduce the original toxicity to a certain extent. The property of medicine is strengthened year by year, and the effect of alternate use is not very satisfactory. The actual dilution of agricultural insecticides has far exceeded its limited range, and the chemical residues in agricultural products are far from meeting the requirements of pollution-free. The increasing demand for pesticides has caused the aggravation of rural environmental pollution, and its residues are harmful to the human body. It cannot be ignored. Contents of the invention [0003] The o...
