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 use against beetles, including honeycomb extracts, turnip extracts, tripterygium extracts, thousand hammer extracts, anaconda snakes extracts, cicada slough extracts, Gentiana extracts, iris extract, chamaejasma extract and azadirachtin in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct the honeycomb, Chinese catkins, and Tripterygium wilfordii 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 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; decoct Qianda hammer, anaconda, cicada slough, Gentiana, iris, and chamaejamas with water twice, 1 hour each time, combine the decoction, filter, concentrate the filtrate, and put Cool, add ethanol to make the ethanol content 65%...

Embodiment 2

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

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on the beetles 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 are also good.

Embodiment 3

[0036] This example verifies the killing rate of the pharmaceutical composition on various pests.

[0037] Select 10,000 beetles, wheat round spiders, mole crickets, red spiders, scarabs, scale insects, tortrix, leafhoppers, pear psyllids, and root-knot nematodes each, and group them respectively, and use the drug prepared in Example 1 to make the same concentration The medicinal liquid of each group is sprayed respectively to the pests of each group, and after 1 hour, the killing rate of various pests is checked, and 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 beetles, 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 the Beatles.

Abstract

The invention discloses a pharmaceutical composition used for beetles. The pharmaceutical composition comprises nidus vespae extract, fructus ulmi extract, tripterygium glycosides extract, Lindera chunii Merr. extract, Caesalpinia minax extract, periostracum cicada extract, gentiana macrophylla extract, Iris tectorum Maxim. extract, radix euphorbiae lantu extract and azadirachtin. The pharmaceutical composition is capable of killing the beetles in a targeted manner, free of toxic and side effects on the natural enemies of the beetles, good in safety, good in biodegrability, free of pollution and pungent smell, free of environment toxic effect, free of residues in animal bodies, incapable of destroying ecological balance, small in influence on crop growth environments, good in permeabilityand wetting performance, capable of interfering the central nervous systems of the beetles, capable of inhibiting beetle egg development, less prone to tolerance generation, quick in action and suitable for being widely popularized and used 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 beetles. 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 most farmers...
