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 thrips, including purple bead leaf extract, light powder extract, camphor extract, chrysalis extract, small revival extract, radish seed extract, notopterygium extract Gorgon fruit extract, betel extract and enidine thiamine, the components of which are as follows:

[0024]

[0025]

[0026] Its preparation method: decoct purple pearl leaves, light powder, and camphor 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 reduces Concentrate under pressure until the relative density is about 1.15, and prepare the medicinal liquid for later use; Add water for decoction twice, 1 hour each time, combine the decoction, filter, and concentrate the filtrate , let it cool, add ethanol to make the ethanol content 65%, let it stand overnight, filter, concentrate the fil...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition against thrips 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 thrips in the three stages of ovum, larva and adult respectively, then uses insecticides respectively for thrips in each stage, and tests the effect of each group of insecticides. kill rate, as shown in the table below:

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

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on thrips in the larvae state, and this product has the best insecticidal effect, and the killing effect is remarkable, even the most difficult to kill eggs have a 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, burdock, and thrips, and group them separately, and use the medicine prepared in Example 1 to make a medicine solution of the same concentration , 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 thrips, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used For the extermination of thrips.

Abstract

The invention discloses a pharmaceutical composition for killing thrips, which comprises purple bead leaf extract, light powder extract, camphor extract, chrysalis extract, small revival extract, radish seed extract, notopterygium extract extract, Gorgon seed extract, betel extract and enidine thiamine. The pharmaceutical composition described in the present invention can kill thrips in a targeted manner, and has no toxic or side effects on natural enemies of thrips, has good safety, good biodegradation, no pollution and irritating smell, and no environmental toxicity. There is no residue in the animal body, does not destroy the ecological balance, and has little impact on the crop growth environment; it has good permeability and moisture, interferes with the nervous system of the insect body, inhibits the synthesis and development of insect eggs, and is not easy to develop drug resistance; quick-acting Well, it 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 pharmaceutical composition for killing thrips. 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 suitable, and mos...
