Problems solved by technology

However, when this kind of chemical pesticide is promoting green and protecting the environment today, many highly toxic and high residue chemicals have been limited or discontinued. In addition, due to the different types of pests, various pests have different levels of pesticide resistance and resistance. There are large differences, so that the insecticidal effect of chemical agents is prone to drug-resistant pests, so it is necessary to propose insect repellents for different insects to prevent specific insects, but there is no corresponding report so far

Embodiment 1

[0023] This example provides a pharmaceutical composition for killing spider mite, including alum extract, veratrum extract, pomegranate peel extract, saponins thorn extract, cumin extract, small revival extract, Qingming willow extract , Yarrow Extract, Magnolia Extract and Thiamethoxam in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct alum, veratrum, and pomegranate peel with water twice, 2 hours each time, combine the decoction, add ethanol to filter and concentrate, add 3 times the amount of water, fully stir, refrigerate for 48 hours, filter, and the filtrate is decompressed Concentrate to a relative density of about 1.27, and prepare the medicinal liquid for later use; add saponins, fennel, small Huanhun, Qingming willow, yarrow, and magnolia to decoction twice, each time for 0.5 hours, combine the decoctions, filter, and concentrate the filtrate. Let it cool, add ethanol to make the ethanol content 65%, let it stand overnight, ...

Embodiment 2

[0029] This example verifies the killing rate of spider mite by comparing the pharmaceutical composition with common insecticides on the market.

[0030] Select the common insecticides on the market: P. lilacinus water agent, nematicide, special root thread agent, and nereistin insecticide.

[0031] Group according to different insecticides, each group prepares 1000 spider mites in three stages of eggs, larvae, and adults, and then uses insecticides on spider mites in each stage, and tests each group of insecticides kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on spider mite

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on spider mites in the larval state, and this product has the best insecticidal effect, and the killing effect is remarkable, even the most difficult to kill insect eggs have a good killing effect .

Embodiment 3

[0036] This example verifies the killing rate of the pharmaceutical composition on various pests.

[0037] Select 10,000 scarabs, beetles, leafhoppers, borers, pear psyllids, scale insects, spinach moths, mole crickets, burdock, and red spiders, and group them separately, and use the medicine prepared in Example 1 to make a medicine solution of the same concentration , spray the pests of each group respectively, and after 1 hour, check the killing rate of various pests, the results are shown in the following table:

[0038] Table 2 The killing effect of the drug on various pests

[0039] group

[0040] It can be seen from the above table that the medicine prepared in Example 1 has a good killing effect only on red spiders, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used Used for killing spider mites.

Abstract

The invention discloses a preparation method of a medicinal composition for killing red spider mites, which comprises the following steps: 1) preparing raw materials; 2) decocting alum, veratrum, and pomegranate peel with water for two times, and the medicinal liquid for later use; 3) soap Add water to decoct the horned thorn, cumin, small Huanhun, Qingming willow, yarrow, and magnolia twice, filter, and concentrate the filtrate to a relative density of 1.15; 4) Merge the liquid medicine; 5) Adjust the pH value of the solution; 6) Filter, Filling, sterilization, that is. The pharmaceutical composition described in the present invention can kill spider mite in a targeted manner, has good safety, good biodegradation, no pollution and irritating odor, no environmental toxicity, no residue in animals, and no damage to ecological balance. It has little impact on the crop growth environment; it has good permeability and wetness, interferes with the nervous system of insects, inhibits the synthesis and development of insect eggs, and is not easy to develop drug resistance; it has good quick effect and is suitable for widespread application in pest control.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a preparation method of a medicinal composition for killing spider mites. Background technique [0002] Chemical agents play an important role in the control of crop diseases and insect pests, but the residues of drugs lead to the deterioration of natural ecosystems, which has become a major issue of international concern and urgently to be solved. In our country, since the 20th century, due to the single use of chemical pesticides, the harmful elements in agricultural products have exceeded the standard, which directly endangers the health and survival of the people. For this reason, the country attaches great importance to and formulated the "Medium and Long-term Science and Technology Development Program Outline" to encourage research and development Environmentally friendly fertilizers and pesticides. Today's farmers' "seeking speed" mentality i...
