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 borer worms, including camphor extract, sage extract, Rhizome extract, Senecio extract, betel extract, Caper scaper extract, Xu Changqing extract, human Lemongrass Extract, Zebra Leaf Extract, and Promethrin in the following quantities:

[0024]

[0025]

[0026] Its preparation method: add water to decoct camphor, succulents, and rhubarb for two times, 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 1.8, and prepare the liquid medicine for later use; add Senecio, Qingcun, Capiter, Xu Changqing, Herringbone Grass, and Zeiziye to decoct twice, each time for 1 hour, combine the decoction, filter, and concentrate Let the filtrate cool, add ethanol to make the ethanol content 65%, let it stand overnight, filter, co...

Embodiment 2

[0029] This example verifies that the medicinal composition has a killing rate against borer worms compared with common insecticides on the market.

[0030] Select the common insecticides on the market: P. lilacinus aqua, nematicide, special root thread agent, and fenethrin insecticide.

[0031] Grouping according to different insecticides, each group prepared 300 pod worms in the three stages of eggs, larvae and adults respectively, and then used insecticides on the pod worms in each stage respectively, and tested 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 borer-eating insects

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on the larva state of the borer.

Embodiment 3

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

[0037] Select 3000 each of borers, beetles, leafhoppers, red spiders, pear psyllids, scale insects, spodoptera, mole crickets, and burdock, and group them respectively, and use the drugs prepared in Example 1 to make medicinal solutions of the same concentration. Spray the pests of each group. After 1 hour, check the killing rate of various pests. 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 borer worms, 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 borer worms.

Abstract

The invention discloses a preparation method of a pharmaceutical composition for rapidly killing green fruitworms. The method comprises the following steps: 1) preparing raw materials; 2) adding waterinto camphor, polygonum aviculare and cyrtomium fortune to decoct twice, thereby obtaining medicinal liquor for later use; 3) adding water into groundsel, bete pepper, euphorbia lathyris, paniculateswallowwort root, kummerowia striata and callicarpa nudiflora to decoct twice, filtering, and concentrating filtrate until the relative density is 1.8; 4) merging the medicinal liquor; 5) regulating the pH value of the solution; and 6) filtering, filling and sterilizing, thereby obtaining the pharmaceutical composition. The pharmaceutical composition disclosed by the invention is capable of killing green fruitworms in a targeted manner, is high in safety, excellent in biological degradability and free of pollution and pungent smell, does not have any environmental toxic effect, does not have any residue in animal bodies, does not destroy the ecological balance and has slight influence on a crop growth environment. Moreover, the pharmaceutical composition has excellent permeability and wetting property, is capable of interfering with the central nervous systems of worms and inhibiting growth and development of worm eggs, is less prone to drug tolerance, and is high in quick-acting property, thus being worthy of being widely popularized and used in the pest control aspect.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a preparation method of a pharmaceutical composition for quickly killing and killing borerworms. 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' "s...
