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 aphids, including the extract of Petunias chinensis, the extract of Cranegrass buds, the extract of Leiwan, the extract of Alisma japonica, the extract of Sophora japonica, the extract of Qianda hammer, the extract of nutmeg Extract, Xu Changqing Extract, Magnolia Magnolia Extract and Indoxacarb, the amounts are as follows:

[0024]

[0025]

[0026] Its preparation method: add water to decoct morning glory seeds, crane grass buds, and thunder pills twice, each time for 2 hours, combine the decoctions, add ethanol to filter and concentrate, add 3 times the amount of water, fully stir, refrigerate for 48 hours, filter, and the filtrate Concentrate under reduced pressure to a relative density of about 1.27, and prepare the medicinal liquid for later use; Add water for Alisma, Sophora japonica, Thousand Hammer, Nutmeg, Xu Changqing, Magnolia Magnolia and decoct twice, each time for 0.5 hours, combine the d...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition on aphids 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, each group prepares 1000 aphids in the three stages of eggs, larvae and adults respectively, and then uses insecticides on the aphids in each stage respectively, and tests 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 aphids

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on aphids 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, vetch, and aphids, and group them respectively, and use the medicine prepared in Example 1 to make a medicinal solution of the same concentration. Spray the pests of each group separately, and check the killing rate of various pests after 1 hour. The results are shown in the table below:

[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 aphids, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used for for the extermination of aphids.

Abstract

The invention discloses a preparation method of a medicinal composition for killing aphids, which comprises the following steps: 1) preparing raw materials; 2) adding water to decoct the petunias, crane grass buds, and thunder pills for two times, and the medicinal liquid for later use; 3) Alisma, Sophora japonica rice, Thousand hammers, Nutmeg, Xu Changqing, Magnolia magnoli, decoct 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 , filled, sterilized, and obtained. The pharmaceutical composition described in the present invention can kill aphids 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 the ecological balance. The crop growth environment has little impact; it has good permeability and wetness, 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 medicinal composition for killing aphids. 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 ...
