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 mole crickets, including extracts of hives, gentiles, pomegranate peels, notopterygium, turmeric extracts, Xiaofeiyang extracts, Polygonatum extracts, and daughters of daughters Extract, Guarenia Herb Extract and Matrine in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct the honeycomb, shijunzi, and pomegranate peel 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 is decompressed Concentrate to a relative density of about 1.8, and prepare the liquid medicine for later use; decoct notopterygium, turmeric, Xiaofeiyang, Polygonatum, Qianjinzi, and melon kernel grass with water twice, each time for 1 hour, combine the decoction, filter, concentrate the filtrate, and put Cool, add ethanol to make the ethanol content 65%, let it stand o...

Embodiment 2

[0029] This example verifies the killing rate of mole crickets by comparing the pharmaceutical composition with common insecticides on the market.

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

[0031] Group according to different insecticides, prepare 300 mole crickets in three stages of eggs, larvae, and adults for each group, and then use insecticides on mole crickets in each stage to test the killing effect of each group of insecticides. kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on mole crickets

[0033]

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

Embodiment 3

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

[0037] Select 3000 mole crickets, beetles, leafhoppers, red spiders, wheat round spiders, pear psyllids, scale insects, spodoptera, vetch, and root-knot nematodes, and group them respectively, and use the medicine prepared in Example 1 to make the same Concentration of liquid medicine, spray each group of pests respectively, after 1 hour, check the killing rate of various pests, the results are shown in the table below:

[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 mole crickets, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used for For the extermination of mole crickets.

Abstract

The invention discloses a preparation method of a mole cricket killing agent unlikely to cause pesticide resistance. The method includes the following steps of preparing raw materials; decocting beehives, quispualis indica and pericarpium granati with water twice to obtain pesticide liquid for use; decocting notopterygium roots, curcuma aromatica, euphorbia hypericifolia, polygonatum sibiricum, moleplant seeds and aconitum gymnandrum maxim with water twice, conducting filtration to obtain a filtrate, and then concentrating the filtrate till the relative density is 1.8; mxing all pesticide liquid; adjusting the pH value of the mixed liquid; conducting filtration, filling and sterilization to obtain the finished product. The pesticide composition can specifically kill mole crickets and is high in safety, excellent in bio-degradation, free of pollution, pungent smell, a toxic effect on the environment, residues in the bodies of animals and damage to the ecological balance, less in influence on the growth environment of crops, great in permeability and wettability, capable of disturbing the neural center systems of the mole crickets and inhibiting the generation and growth of eggs of the mole crickets, unlikely to cause the pesticide resistance, great in fast-acting property, and suitable for wide application and popularization in prevention and control of pests.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a method for preparing a mole cricket exterminator which is not easy to produce drug resistance. 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' "see...
