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 Spodoptera litura, including the extracts of sage, Torreya seed extract, pomegranate peel extract, Xiaofeiyang extract, Qingfengteng extract, banyan barbarum extract, and Qumai extract , Qingdai Extract, Coptis Rhizoma Extract and Indoxacarb, the components of which are as follows:

[0024]

[0025]

[0026] Its preparation method: add water to decoct the scorpion, torreya, and pomegranate peel twice, each time for 2 hours, 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 1.15, and prepare the liquid medicine for later use; add water to decoct Xiaofeiyang, Qingfengteng, banyan mustache, Qumai, Qingdai, and Coptis chinensis twice, each time for 1 hour, combine the decoction, filter, concentrate the filtrate, and let it cool , add ethanol ...

Embodiment 2

[0029] This example verifies the killing rate of the medicinal composition against Spodoptera litura compared with common insecticides on the market.

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

[0031] Grouping according to different insecticides, each group prepares 1000 Spodoptera litura in three stages of eggs, larvae and adults respectively, and then uses insecticides on Spodoptera litura in each stage, and tests each group of insecticides The killing rate of the agent is shown in the table below:

[0032] Table 1 The killing effect of insecticides on Spodoptera litura

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on Spodoptera litura in the larval state. 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, bonito, and spodoptera litura, 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 Spodoptera litura, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used to kill insects. Used for killing Spodoptera litura.

The pharmaceutical composition described in the present invention can kill Spodoptera litura in a targeted manner, has no toxic and side effects on natural enemies of Spodoptera litura, has good safety, good biodegradation, no pollution and pungent smell, and no environmental toxicity , there is no residue in the animal body, does not destroy the ecological balance, and has little impact on the crop growth environment; it has good permeability and moisture, interferes with the nervous system of the insect body, 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 wide popularization and application in pest control.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a pharmaceutical composition for killing Spodoptera litura. 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 is not suitable...
