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 embodiment provides a pharmaceutical composition for killing midges, including alum extract, pepper extract, light powder extract, golden needle extract, turmeric extract, cinnamon extract, viper extract, and jackfruit extract Extract, Qianta Hammer Extract and Matrine in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct alum, Chinese prickly ash, 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 48 hours, filter, and the filtrate is concentrated under reduced pressure When the relative density is about 1.15, the medicinal liquid is set aside; golden needles, turmeric, cinnamon, Viper, jackal, and thousand hammers are added to water and decocted twice, each time for 1 hour, combined decoction, filtered, concentrated filtrate, put Cool, add ethanol to make the ethanol content 65%, let it stand overnigh...

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] Group according to different insecticides, each group prepares 1000 midges in the three stages of eggs, larvae and adults, and then uses insecticides on the midges in each stage to test the killing of each group of insecticides rates, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on midge

[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 pesticidal composition for killing midges. The pesticidal composition comprises an alum extract, a Chinese prickly ash extract, a calomel extract, a Hemerocallis root extract, a radix curcumae extract, a cinnamon extract, an Agkistrodon extract, a Flemingia philippinensis extract, a Spreading Hedyotis extract and matrine. The pesticidal composition provided by the invention has the following advantages: capability of targetedly killing the midges, no toxic and side effects to natural enemies of the midges, good safety, good biodegradation, no pollution and irritatingodor, no environmental toxicity, no residues in animals, no damage to ecological balance, little influence on the growth environment of crops, good permeability and wettability, interference to the central nervous system of a midge body, inhibition of combination and development of midge eggs, insusceptibility to generation of pesticide resistance, good fast-acting property, and applicability to extensive popularization and application in the fields of prevention and treatment of pests.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a pharmaceutical 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 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 ...
