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] The present embodiment provides a pharmaceutical composition for killing leafhoppers, including extracts of babubu extracts, tripterygium twig extracts, aloe extracts, cinnamon extracts, thousand hammer extracts, saponins thorn extracts, magnolia extracts, Cucurbit Tea Extract, Polygonum Capsicum Extract, and Thiamethoxam in the following quantities:

[0024]

[0025]

[0026] Its preparation method: add water to decoct babu, tripterygium wilfordii, and aloe 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 1.8, and prepare the liquid medicine for later use; cinnamon, thousand hammers, saponins, magnolia, gourd tea, and spicy Polygonum, add water and decoct twice, each time for 1 hour, combine the decoctions, filter, and concentrate the filtrate. Let it cool, add ethanol...

Embodiment 2

[0029] This example verifies the killing rate of the medicinal composition on leafhoppers 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 300 leafhoppers in three stages of eggs, larvae, and adults, and then uses insecticides on leafhoppers in each stage to test each group of insecticides kill rate, as shown in the table below:

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

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on leafhoppers 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 3000 leafhoppers, beetles, red spiders, borers, pear psyllids, scale insects, spodoptera, mole crickets, burdock, and wheat round spiders, and group them respectively, and use the medicine prepared in Example 1 to make the same concentration of The liquid medicine is sprayed on the pests of each group respectively, and after 1 hour, the killing rate of various pests is checked, and the results are shown in the following table:

[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 leafhoppers, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used Used to kill leafhoppers.

Abstract

The invention discloses a preparation method of a medicinal composition for poisoning and killing leafhoppers, comprising the following steps: 1) preparing raw materials; 2) adding water to decoct ababa, tripterygium wilfordii, and aloe for two times, and preparing the medicinal liquid for later use; 3) cassia cinnamon . Filling, sterilization, that is. The pharmaceutical composition described in the present invention can kill leafhoppers in a targeted manner, has good safety, good biodegradation, no pollution and irritating odor, no environmental toxicity, no residue in animals, and no damage to ecological balance. It has little impact on the crop growth environment; it has good permeability and wetness, interferes with the 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 poisoning leafhoppers. 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" mentalit...
