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 medicinal composition for killing aphids, including purple bead leaf extract, arsenic extract, crane grass bud extract, Qingming willow extract, honeysuckle extract, yarrow extract, cinnamon extract , Dipsacus extract, Polygonum sphaerocarpa extract and Mechlorfenuron, the components are as follows:

[0024]

[0025]

[0026] The preparation method: decocting the purple bead leaf, arsenic, and crane grass buds with water twice for 2 hours each time, combine the decoction, add ethanol to filter and concentrate, add 3 times the amount of water, fully stir, refrigerate for 48 hours, filter, The filtrate was concentrated under reduced pressure to a relative density of about 1.15, and the medicinal solution was ready for use; qingming willow, honeysuckle, yarrow, cinnamon, dipsacus, and Polygonum vulgare were decocted twice with water for 1 hour each time, combined the decoction, filtered, and concentrated The filtrate, let cool, add ethanol to make t...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition on aphids compared with common pesticides on the market.

[0030] Choose common insecticides on the market: Porphyridium lavender water, nematicides, specific root nematodes, thiamethoxam insecticides.

[0031] According to different insecticides, each group prepares 1,000 aphids at the three stages of eggs, larvae, and adults, and then applies insecticides to the aphids at each stage to test the killing of each group of insecticides Rate, as shown in the following table:

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

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate of aphids in the larval state, this product has the best insecticidal effect, and the killing effect is remarkable, even the most difficult to kill insect eggs have a better killing effect.

Embodiment 3

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

[0037] 10,000 each of beetles, beetles, leafhoppers, heartworms, psyllids, scale insects, worms, mole crickets, mud, and aphids were selected and divided into groups. The medicine prepared in Example 1 was used to prepare a liquid medicine of the same concentration. Spray the pests in each group separately. 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] It can be seen from the above table that the medicine prepared in Example 1 only has a good killing effect on aphids, and has very limited killing effects on other pests. This proves that this product is highly targeted and can only be used To kill aphids.

Abstract

The invention discloses a pharmaceutical composition for killing aphids. The pharmaceutical composition is prepared from a folium callicarpae formosanae extract, an arsenolite extract, a bud of hairyvein agrimony extract, a salix magnifica extract, a caulis lonicerae extract, an alpine yarrow herb extract, a cortex cinnamomi extract, a radix dipsaci extract, a red-knees herb extract and chlorbenzuron. The pharmaceutical composition disclosed by the invention can be used for specifically killing the aphids, has the advantages of freeness from toxic and side effects on natural enemies of the aphids, high safety, high biodegradability, freeness from pollution and pungent smell, freeness from environmental toxicity, no residues in animals, no damage to biological balance, low influence on thecrop growing environment, higher permeability, higher moistening property, capabilities of interfering the central nervous system of the aphids and restraining synthetic development of worm eggs, non-tendency to pesticide resistance and high fast-acting property, and is suitable for being widely popularized and applied on the aspect of pest prevention and control.

Description

Technical field [0001] The invention belongs to the field of agricultural technology development, and specifically relates to a pharmaceutical composition for killing aphids. Background technique [0002] Chemical agents play an important role in the prevention and control of crop diseases and insect pests. However, the residue of drugs has caused the natural ecosystem to deteriorate day by day. This has become a major issue of international common concern and urgent solution. In our country, since the twentieth century, the single use of chemical pesticides has caused the harmful elements in agricultural products to exceed the standards, which directly endangers the health and survival of the people. For this reason, the state attaches great importance to and formulated the "Medium and Long-term Science and Technology Development Program Outline", which aims to encourage research and development. Environmentally friendly fertilizers and pesticides. Today’s farmers’ mentality of...
