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 Trichinella, including garlic extract, Zanthoxylum bungeanum extract, aloe extract, Euryale gorgon extract, Xue Jianchou extract, cucumber ren grass extract, camphor willow extract , Iris Extract, Polygonatum Polygonatum Extract and Lignin in the following quantities:

[0024]

[0025]

[0026] Its preparation method: add water to garlic, Chinese prickly ash, aloe and decoct 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 concentrated under reduced pressure to The relative density is about 1.8, and the liquid medicine is used for later use; Gorgon fruit, xuejianshou, cucumber kernel grass, camphor willow head, iris, Polygonatum odoratum, add water and decoct twice, each time for 1 hour, combine the decoction liquid, filter, concentrate the filtrate, put Cool, ad...

Embodiment 2

[0029] This example verifies the killing rate of the medicinal composition against the extrinsic moth compared with common insecticides on the market.

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

[0031] Grouping according to different insecticides, each group prepares 300 cutworms in the three stages of eggs, larvae and adults respectively, and then uses insecticides on the cutworms in each stage respectively, and tests each group to kill Insecticide kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on Spodoptera moth

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on the larval state of the Spodoptera moth, and this product has the best insecticidal effect, and the killing effect is remarkable, even the most difficult to kill eggs are also better killed Effect.

Embodiment 3

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

[0037] Select 3000 spodoptera, beetles, leafhoppers, red spiders, wheat round spiders, pear psyllids, scale insects, mole crickets, burdock, 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 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 has a good killing effect only on Spodoptera moth, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used to kill insects. Used for the extermination of Spodoptera moth.

Abstract

The invention discloses a method for preparing a homona magnanima killing agent capable of avoiding environmental pollution. The method comprises the following steps: (1) preparing raw materials; (2)adding water into garlic, Chinese prickly ash and aloe, and decocting twice to obtain liquid medicine for later use; (3) adding water into gorgon fruit, teucrium viscidum, all grass of polygala japonica houtt, rhizome of canereed spiralflag, iris tectorum and radix polygonati officinalis, decocting twice, filtering, and concentrating the filtrate until the relative density is 1.8; (4) merging theliquid medicine; (5) regulating the pH value of the solution; and (6) filtering, filling and sterilizing, thereby obtaining the homona magnanima killing agent. The pharmaceutical composition disclosedby the invention is capable of specifically killing homona magnanima, good in safety and biodegradability, does not have pollution or pungent smell, does not have environmental toxicity, does not have residues in animal bodies, does not destroy the ecological balance and has slight influence on crop growth. The agent has excellent permeability and wetting property, achieves effects of interferingthe central nervous system of the homona magnanima bodies and inhibiting synthesis and development of eggs, and difficultly produces drug tolerance. The agent is excellent in fast-acting property andsuitable for wide popularization and application in the pest control aspect.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a preparation method of an environment-friendly exterminator for the tortrix moth. 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" ...
