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 scarabs, including pomegranate bark extract, Vitex bark extract, purple bead leaf extract, cinnamon extract, thousand hammer extract, Qingfengteng extract, Qumai extract extract, fennel seed extract, huangpi root extract and diflubenzuron, the quantities are as follows:

[0024]

[0025]

[0026] Its preparation method: decoct the pomegranate peel, turmeric peel, and purple pearl leaves with water twice, each time for 2 hours, combine the decoction, add ethanol to filter and concentrate, add 3 times the amount of water, stir well, refrigerate for 48 hours, filter, The filtrate is concentrated under reduced pressure to a relative density of about 1.8, and the liquid is used for later use; cinnamon, thousand hammers, Qingfengteng, oatmeal, green scorpion, and yellow root are decocted twice, each time for 1 hour, and the decoctions are combined and filtered. over, concentrate the filtrate, let it cool, ad...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition on scarabs compared with common insecticides on the market.

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

[0031] Group according to different insecticides, prepare 300 scarabs in three stages of eggs, larvae, and adults for each group, and then use insecticides on scarabs in each stage to test the killing effect of each group of insecticides. kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on scarabs

[0033]

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

Embodiment 3

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

[0037] Select 3,000 scarabs, beetles, leafhoppers, borers, pear psyllids, scale insects, spodoptera, mole crickets, burdock, and red spiders, and group them separately, and use the medicine prepared in Example 1 to make a medicinal 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 only has a good killing effect on scarabs, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used for Yu the killing of scarabs.

Abstract

The invention discloses a preparation method of a pharmaceutical composition for killing scarab beetles, which comprises the following steps: 1) preparing raw materials; 2) decocting pomegranate peel, jasmine bark, and purple pearl leaves with water for two times, and the medicinal solution is set aside; 3) Add water to decoct cinnamon, thousand hammers, Qingfengteng, Qumai, Qingyuzi, and Huangpigen twice, filter, and concentrate the filtrate to a relative density of 1.8; 4) Combine the liquid medicine; 5) Adjust the pH value of the solution ; 6) Filter, fill, sterilize, and obtain. The pharmaceutical composition described in the present invention can kill scarabs in a targeted manner, has good safety, good biodegradation, no pollution and irritating odor, no environmental toxicity, no residue in animals, and does not destroy ecological balance. The crop growth environment has little impact; it has good permeability and moisture, interferes with the central 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 pharmaceutical composition for killing scarab beetles. 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" ment...
