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 rice, including Veratrum extract, Lei Wan extract, Agrimony extract, Polygala extract, Stephania japonica extract, capers extract, madder extract, Gentiana extract, Magnolia magnolia extract and promethrin in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct veratrum, ray pill, and Agrimony 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 solution for later use; add polygala, daughter of a thousand gold seeds, capers, madder, Gentiana chinensis, and Magnolia magnolia to water and decoct twice, each time for 1 hour, combine the decoctions, filter, concentrate the filtrate, and let it cool , add ethanol so that the ethanol...

Embodiment 2

[0029] This example verifies the killing rate of the medicinal composition on rice vertical 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, prepare 1000 rice verticals in three stages of eggs, larvae, and adults for each group, and then use insecticides on the rice verticals in each stage to test the effect of each group of insecticides kill rate, as shown in the table below:

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

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on rice larvae, and this product has the best insecticidal effect, and the killing effect is remarkable, even the most difficult to kill insect eggs. .

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 rice, 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 rice, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used It is used for killing rice vertically.

Abstract

The invention discloses a medicinal composition for killing rice vertebrae. Chinensis extract, Xinyi extract and cypermethrin. The pharmaceutical composition described in the present invention can kill rice plants in a targeted manner, has no toxic and side effects on the natural enemies of rice plants, has good safety, good biodegradation, no pollution and irritating odor, and has no environmental toxicity. There is no residue in the animal body, does not destroy the ecological balance, and has little impact on the growing environment of crops; it has good permeability and wettability, interferes with the nervous central system of the parasite, inhibits the synthesis and development of the eggs, and is not prone to drug resistance; fast-acting Good, 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 medicinal composition for killing rice plants. 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 most ...
