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

[0022] The insecticide of the present invention is prepared by using the following raw materials in weight proportions: 10 parts of calla lily, 50 parts of deer's grass, 5 parts of vine, 5 parts of mother grass, 20 parts of comfrey, 5 parts of peylan, 0.5 parts of polysorbate, 0.5 parts of dimethyl sulfoxide, 1 part of turpentine oil, 1 part of ethanol, 0.5 parts of arboric acid and 50 parts of demineralized water. Among them, calla lily, chrysanthemum, vine, mother-in-law, comfrey, and Peilan are all made of dried raw materials.

[0023] The specific preparation method is as follows:

[0024] (1) Divide the demineralized water into demineralized water A and demineralized water B according to the mass ratio of 2:1;

[0025] The polysorbate, dimethyl sulfoxide, turpentine, and arholic acid were successively dissolved in demineralized water A under continuous stirring to form a mixture;

[0026] (2) Add ethanol to the mixture in step (1), and stir well until uniform;

[0027]...

Embodiment 2

[0033] The insecticide of the present invention is prepared by using the following raw materials in weight proportions: 20 parts of calla lily, 60 parts of deer's grass, 10 parts of vine vine, 10 parts of mother grass, 30 parts of comfrey, 10 parts of perrin, 5 parts of polysorbate, 5 parts of dimethyl sulfoxide, 3 parts of turpentine, 3 parts of ethanol, 1 part of argonic acid and 100 parts of demineralized water.

[0034] A preparation method of an insecticide, comprising the following steps:

[0035] (1) Divide the demineralized water into demineralized water A and demineralized water B according to the mass ratio of 3:1;

[0036] The polysorbate, dimethyl sulfoxide, turpentine, and arholic acid were successively dissolved in demineralized water A under continuous stirring to form a mixture;

[0037] (2) Add ethanol to the mixture in step (1), and stir well until uniform;

[0038] (3) Use clean water to decoct the comfrey 5 times, each decocting for 1 hour, mix and concen...

Embodiment 3

[0044] The insecticide of the present invention adopts the raw material preparation of following weight ratio:

[0045] 14 parts of calla lily, 52 parts of chrysanthemum, 8 parts of vine, 7 parts of mother grass, 22 parts of comfrey, 6 parts of perrin, 3 parts of polysorbate, 5 parts of dimethyl sulfoxide, 1 part of turpentine, 2 parts of ethanol 0.8 part, 0.8 part of arboric acid and 85 parts of demineralized water.

[0046] The preparation method is as in Example 2.

[0047] Comparing the prepared insecticide with 2.5% dichlorpyr EC proved that the insecticide of the present invention was 1000, 1500, 2000 times diluted, and the control efficiency was 100%, 100%, 99% respectively one day after the application of the insecticide to the green vegetables. ; And 2.5% 1,600-fold diluted medicament anti-efficiency of 1,600-fold dichloride EC is only about 70%. After 3 days of spraying, the insecticide 1000, 1500, 2000 times dilution of the present invention has an anti-efficiency...

Abstract

The invention discloses an insecticide and a preparation method thereof. The insecticide is prepared by using the following raw materials in the weight ratio: 10-20 parts of calla lily, 50-60 parts of deer's grass, 5-10 parts of vine vine, mother-in-law 5-10 parts of grass, 20-30 parts of comfrey, 5-10 parts of Perrin, 0.5-5 parts of polysorbate, 0.5-5 parts of dimethyl sulfoxide, 1-3 parts of turpentine, 1-3 parts of ethanol, flower 0.5-1 part of catallic acid and 50-100 parts of demineralized water. The insecticide of the present invention is pollution-free, safe and has obvious insecticidal effect.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an 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 object of the present ...
