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 Liriomyza spp., including crane lice extract, morning glory seed extract, garlic extract, chrysoprosis extract, houttuynia cordata extract, anaconda snake bougainvillea extract, Notopterygium extract, nutmeg extract, green wood extract and osthole in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct crane lice, morning glory, and garlic twice with water, 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 medicinal liquid for later use; Add water for decoction twice, each time for 1 hour, combine the decoctions, filter, Concentrate the filtrate, let it cool, add ethanol to make the ethanol content 65%, let stand overnight, filter, concentrate the filtrate under r...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition against Liriomyza sativae 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 Liriomyza sativae in three stages of eggs, larvae and adults respectively, and then uses insecticides on Liriomyza sativae in each stage respectively, and tests each group of insecticides The killing rate of the agent is shown in the table below:

[0032] Table 1 The killing effect of insecticides on Liriomyza sativae

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on the larval state of Liriomyza sativae, and this product has the best insecticidal effect, and the killing effect is remarkable, and it can kill even the most diffic...

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 liriomyza, and group them respectively, and use the medicines prepared in Example 1 to make medicines of the same concentration. liquid, spray the pests of each group respectively, and after 1 hour, check the killing rate of various pests, 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 Liriomyza sativae, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only Used for killing Liriomyza spp.

Abstract

The invention discloses a pharmaceutical composition for killing liriomyza sativae, containing common carpesium fruit extract, pharbitis seed extract, garlic extract, radix gentianae extract, houttuynia cordata extract, fructus nelumbinis root extract, notopterygium incisum extract, myristica fragrans extract, radix aristolochiae extract and cnidium lactone. The pharmaceutical composition disclosed by the invention can kill liriomyza sativae in a targeted manner, has no toxic or side effect to the natural enemy of liriomyza sativae, is good in safety and good in biodegradation, does not have pollution or pungent smell, does not have environmental toxic effect, does not have residues in an animal body, cannot damage ecological balance, and is slight in influence on growth of crops, has goodpermeability and wettability, disturbs the nerve center system of the insect body, can inhibit the synthesis and development of eggs, and does not generate drug resistance easily, and is good in fast-acting property and suitable for being widely popularized and applied in the aspect of 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 killing Liriomyza sativae. 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 not suitab...
