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 midges, including Agrimony extract, camphor extract, light powder extract, Eupatorium extract, hawthorn extract, ginseng extract, Qingfengteng extract, boa snake Bougainvillea extract, notopterygium extract and diflubenzuron, the amounts are as follows:

[0024]

[0025]

[0026] Its preparation method: decoct Agrimony, camphor, and light powder with water 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 60 hours, filter, and the filtrate is decompressed Concentrate to a relative density of about 1.27, and prepare the liquid medicine for later use; decoct Eupatorium, hawthorn, ginseng, Qingfengteng, anaconda, and notopterygium with water twice, each time for 0.5 hours, combine the decoction, filter, concentrate the filtrate, and put Cold, add ethanol to make the ethanol content 65%, let it stand over...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition against midges 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 insecticides in the three stages of eggs, larvae and adults respectively, and then uses insecticides respectively for the midges in each stage, 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 midges

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on midges 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 10,000 scarabs, beetles, leafhoppers, borers, pear psyllids, scale insects, spinach moths, mole crickets, pods, and midges, 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] As can be seen from the above table, the medicine prepared in Example 1 only has a good killing effect on midges, 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 killing of midges.

Abstract

The invention discloses a preparation method of a drug composition for killing out sitodiplosis mosellana. The method comprises the following steps of (1) preparing raw materials; (2) adding water fordecocting herba agrimoniae, camphor and calomel for twice, and obtaining a medicine liquor for standby use; (3) adding water for decocting herba lycopi, fructus crataegi, ginseng, caulis sinomenii, caesalpinia minax and rhizoma seu radix notopterygii for twice, filtering, and concentrating a filter liquor until the relative density is 1.15; (4) merging the medicine liquors; (5) adjusting a pH value of the solution; (6) filtering, filling, and sterilizing to obtain the drug composition. The drug composition provided by the invention can be specifically used for killing out the sitodiplosis mosellana, has good safety, good biodegradation, no pollution and pungent smell, no environmental toxicity, and no residue in animals, does not damage ecological balance, and has less influence on a cropgrowth environment; has better permeability and wettability, interferes nerve center systems of polypide, inhibits worm egg synthesis development, and is not easy to occur tolerance; has a good fast-acting property, and is suitable to be widely popularized and applied 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 midges. 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" mentality is no...
