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 whitefly, including the extracts of leeches, the extracts of veratrum, the extracts of Cranegrass buds, the extracts of Xuejianxie, the extracts of Qiannianjian, the extracts of Banyan barbarum, and the Flower Extract, Gorgon Seed Extract, Cotton Root Extract and Monocrotophos in the following quantities:

[0024]

[0025]

[0026] Its preparation method: Add water to decoct sage, veratrum, and crane grass buds 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 Concentrate under reduced pressure to a relative density of about 1.15, and prepare the liquid medicine for later use; decoct Xue Jianchou, Qiannianjian, banyan beard, inula, Gorgon seed, and yellow root with water for two times, 1 hour each time, combine the decoction, and filter , concentrate the filtrate,...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition against whitefly compared with common insecticides in the market.

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

[0031] Group according to different insecticides, each group prepares 1000 whiteflies in three stages of eggs, larvae, and adults respectively, and then uses insecticides on whiteflies in each stage respectively, 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 whitefly

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on whitefly in the larval state, and this product has the best insecticidal effect, and the killing effect is remarkable, even the eggs that are most difficult to kill have 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, vetch, and whitefly, and group them respectively, 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] It can be seen from the above table that the medicine prepared in Example 1 only has a good killing effect on whitefly, 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 whitefly.

Abstract

The invention discloses a pharmaceutical composition for killing whitefly, which comprises extracts of leeches, extracts of veratrum, extracts of Cranegrass buds, extracts of xuejianchou, extracts of Qiannianjian, extracts of banyan tree whiskers, Flower Extract, Gorgon Seed Extract, Cotton Root Extract and Monocrotophos. The pharmaceutical composition described in the present invention can kill whitefly in a targeted manner, and has no toxic or side effects on natural enemies of whitefly, 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 whitefly. 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 solved. 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...
