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 the beet armyworm, including the extract of babubu extract, extract of hive, extract of gentie, extract of radish, extract of fennel, extract of viper, extract of jackal , herringbone extract, xuejianxiu extract and diazinon, the components are as follows:

[0024]

[0025]

[0026] Its preparation method: add water to decoct Baibu, Hive, and Shijunzi twice, each time for 2 hours, combine the decoction, add ethanol to filter and concentrate, add 2 times the amount of water, fully stir, refrigerate for 48 hours, filter, and the filtrate is decompressed Concentrate to a relative density of about 1.28, and prepare the medicinal liquid for later use; radish seeds, fennel, viper, jackal, herringbone grass, and xuejianchou are decocted twice, each time for 0.5 hours, and the decoctions are combined, filtered, and concentrated Let the filtrate cool, add ethanol to make the ethanol content 65%, let it stand ov...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition against beet armyworm compared with common insecticides in the market.

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

[0031] Grouping according to different insecticides, each group prepares 1000 beet armyworms in the three stages of eggs, larvae and adults respectively, and then uses insecticides on the beet armyworms in each stage respectively, and tests each group to kill the beet armyworm. Insecticide kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on beet armyworm

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on the beet armyworm 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 ...

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, pods, and beet armyworms, and group them respectively, and use the medicines prepared in Example 1 to make medicines of the same concentration. liquid, 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] As can be seen from the above table, the medicine prepared in Example 1 only has a good killing effect on beet armyworm, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only Used for killing beet armyworm.

Abstract

The invention discloses a preparation method of a pharmaceutical composition for killing beet armyworm. The preparation method comprises the following steps: 1) preparing raw materials; (2) adding water into radix stemonae, nidus vespae and fructus quisqualis, and decocting twice to obtain medicinal liquor for later use; 3) adding water into semen raphani, fennel, long-noded pit viper, radix flemingiae philippinensis, herba kummerowiae striatae and herba teucrii viscidi, decocting for twice, filtering, and concentrating the filtrate till the relative density is 1.15; 4) mixing the medicinal liquor; 5) regulating the pH value of the solution; 6) filtering, filling and sterilizing to obtain the pharmaceutical composition. The pharmaceutical composition disclosed by the invention can be usedfor specifically killing the beet armyworm, has the advantages of high safety, high biodegradability, freeness from pollution and pungent smell, freeness from environmental toxicity, no residues in animals, no damage to biological balance, low influence on the crop growing environment, higher permeability, higher moistening property, capabilities of interfering the central nervous system of the beet armyworm and restraining synthetic development of worm eggs, non-tendency to pesticide resistance and high fast-acting property, and is suitable for being widely popularized and applied on the aspect of pest prevention and 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 beet armyworm. 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 resolved. 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" mentalit...
