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

[0022] This example provides a kind of mole cricket killing agent that is not easy to produce drug resistance, including extracts of succulents, borneol extracts, purple bead leaf extracts, cumin extracts, polygala extracts, iris extracts, and honeysuckle extracts , Polygonum extract, Viper extract and monocrotophos in the following quantities:

[0023]

[0024]

[0025] Its preparation method: Add water to decoct scorpion, borneol, and purple pearl leaves 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 reduced. Concentrate under pressure to a relative density of about 1.15, and prepare the liquid medicine for later use; fennel, polygala, iris, honeysuckle, Polygonum, and viper are decocted twice, each time for 1 hour, combined decoction, filtered, concentrated filtrate, put Cool, add ethanol to make the ethanol content 65%, let i...

Embodiment 2

[0028] This example verifies the killing rate of mole crickets by comparing the pharmaceutical composition with common insecticides on the market.

[0029] Select the common insecticides on the market: P. lilacinus water agent, nematicide, special root thread agent, and thiamethoxam insecticide.

[0030] Group according to different insecticides, each group prepares 1000 mole crickets in the three stages of eggs, larvae and adults respectively, and then uses insecticides on the mole crickets in each stage respectively, and tests the killing effect of each group of insecticides. kill rate, as shown in the table below:

[0031] Table 1 The killing effect of insecticides on mole crickets

[0032]

[0033] 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 go...

Embodiment 3

[0035] This example verifies the killing rate of the pharmaceutical composition on various pests.

[0036] Select 10,000 scarabs, beetles, leafhoppers, borers, pear psyllids, scale insects, spodoptera, mole crickets, vetch, and root-knot nematodes, and group them respectively, and use the medicines prepared in Example 1 to make medicines of the same concentration. liquid, 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:

[0037] Table 2 The killing effect of the drug on various pests

[0038] group

[0039] 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 present invention discloses a mole cricket killer uneasily causing drug resistance. The mole cricket killer includes common knotgrass herb extract, borneol extract, bigleaf beautyberry leaf extract, fennel extract, milkwort root extract, roof iris rhizome extract, honeysuckle stem extract, ciderage extract, long-nosed pit viper extract and monocrotophos. The medicinal composition described inthe present invention can kill mole cricket specifically, has no toxic or side effects on natural enemies of mole cricket, has good safety, good biodegradation, no pollution or irritating odor, no environmental toxicity, and no residues in animals, does not destroy ecological balance, generates little impact on crop growth environment, has good permeability and wettability, interferes with the central nervous system of the inset bodies, inhibits egg synthesis and development, uneasily generates drug resistance, is good in quick-acting effect, and is suitable for widespread promotion and application in pest control.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a mole cricket killing agent 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 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" mentalit...
