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

[0020] The insecticide of the present invention is prepared from the following raw materials in weight ratio: 5 parts of ginkgo testa, 2 parts of A. musilicum powder, 5 parts of zheer root, 2 parts of chrysanthemum, 10 parts of deerbite, 5 parts of comfrey, and 2 parts of perrin 5 parts of synergist (GY-1 pesticide synergist), 5 parts of buprofezin, 2 parts of spinosad and 20 parts of water. Among them, the raw materials of ginkgo seed coat, Zheergen, Huanghuatiao, Luniancao, comfrey and Peilan are all dried raw materials.

[0021] The specific preparation method is as follows:

[0022] (1) Divide the water in the raw material into water A and water B according to the mass ratio of 1:4; take comfrey, add it to water A for decoction, concentrate the decoction obtained to 5 times the original density ;

[0023] (2) Grind Peilan and deerbite into fine powder;

[0024] (3) Mix the comfrey concentrate in step (1) and the fine powder in step (2) and stir evenly;

[0025] (4) Soa...

Embodiment 2

[0028] The insecticide of the present invention is prepared by using the following raw materials in weight proportions: 10 parts of ginkgo seed coat, 5 parts of A. musilicum powder, 10 parts of Zhe'er root, 5 parts of chrysanthemum, 20 parts of chrysanthemum, 10 parts of comfrey, and 5 parts of perrin 10 parts of synergist (GY-1 pesticide synergist), 10 parts of buprofezin, 5 parts of spinosad and 50 parts of water.

[0029] A preparation method of an insecticide, comprising the following steps:

[0030] (1) Divide the water in the raw material into water A and water B according to the mass ratio of 1:7; take comfrey, divide water A into two parts, decoct the comfrey twice, and decoct the obtained The liquid is mixed and concentrated, concentrated to 3 times of the original density;

[0031] (2) Grind Peilan and deerbite into fine powder;

[0032] (3) Mix the comfrey concentrate in step (1) and the fine powder in step (2) and stir evenly;

[0033] (4) Soak the ginkgo seed c...

Embodiment 3

[0036] The insecticide of the present invention is prepared by using the following raw materials in weight proportions: 8 parts of ginkgo seed coat, 4 parts of mirabilis powder, 7 parts of zheer root, 4 parts of chrysanthemum, 16 parts of deerbite, 7 parts of comfrey, and 3 parts of peylan 8 parts of synergist (GY-1 pesticide synergist), 7 parts of buprofezin, 4 parts of spinosad, and 40 parts of water.

[0037] The preparation method is as in Example 2.

[0038] The present invention is diluted at 1:400, and the comparison pesticides are all used according to the instructions, and the control test for cabbage caterpillar is shown in the following table:

[0039]

[0040] As can be seen from the above table, the present invention is equivalent to the effectiveness of the unified killing, which is better than the quick killing.

Abstract

The invention discloses a vegetable insecticide and a preparation method and application thereof. The insecticide is prepared from, by weight, 5-10 parts of ginkgo seed husks, 2-5 parts of metarhizium anisopliae powder, 5-10 parts of herba houttuyniae, 2-5 parts of fructus forsythiae, 10-20 parts of Chinese pyrola herb, 5-10 parts of radix arnebiae, 2-5 parts of herba eupatorii, 5-10 parts of synergist, 5-10 parts of buprofezin, 2-5 parts of spinosad and 20-50 parts of 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 a vegetable 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...
