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 cotton bollworms, including hive extract, morning glory extract, soap alum extract, iris extract, Xu Changqing extract, Renmian leaf extract, box ginseng extract, Polygonatum extract, gourd tea extract and lignanin in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct the honeycomb, morning glory, and saponin twice with water, 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 iris, Xu Changqing, Renmian leaves, boxing ginseng, sealwort, and gourd tea to decoct twice, each time for 1 hour, combine the decoction, filter, concentrate the filtrate, and let it cool , add ethanol so that the ethanol content is 65%, let it stand overn...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition against cotton bollworm 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] Grouping according to different insecticides, each group prepares 1000 cotton bollworms in the three stages of eggs, larvae and adults respectively, and then uses insecticides respectively on the cotton bollworms in each stage, and tests the effect of each group of insecticides. kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on cotton bollworm

[0033]

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

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 cotton bollworms, 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] As can be seen from the above table, the medicine prepared in Example 1 only has a good killing effect on cotton bollworms, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used For the extermination of cotton bollworm.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a medicinal composition for killing cotton bollworms. 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, and ...
