Embodiment 1

[0030] Example 1: 250 parts of Rhizome, 60 parts of Sophora flavescens, 80 parts of Asparagus, 40 parts of dark plum, and 30 parts of Asarum, all of which are dry products. Weigh the Chinese medicinal materials according to the weight ratio of the raw materials, soak Asarum separately in 2 times the weight of water, and put the other four kinds (Shengbaibu, Sophora flavescens, asparagus, and dark plum) together in a large pot with 2 times the weight of water Soak for 1 hour; add 10 times the total weight of all raw materials in proportion to decoct, boil and continue to decoct for 50 minutes, then add asarum (together with soaking water) and decoct for 5 minutes; filter to remove slag, and the obtained water The extract is the pollution-free pesticide of pure traditional Chinese medicine components. Finally, the obtained water extract is concentrated to contain 1 gram of total crude drug per milliliter.

Embodiment 2

[0031] Example 2: 240 parts of Rhizome, 50 parts of Sophora flavescens, 70 parts of Asparagus, 30 parts of dark plum, and 40 parts of Asarum. The raw materials described are dry products. Weigh the Chinese medicinal materials according to the weight ratio of the raw materials, soak Asarum separately in 2 times the weight of water, and put the other four kinds (Shengbaibu, Sophora flavescens, asparagus, and dark plum) together in a large pot with 2 times the weight of water Soak for 2 hours; add water 13 times the total weight of all raw materials to decoct in proportion, after boiling, continue to decoct on low heat for 85 minutes, then add asarum (together with soaking water) and simmer for 4 minutes; filter to remove slag, and the obtained water The extract is the pollution-free pesticide of pure traditional Chinese medicine components. Finally, the obtained water extract is concentrated to contain 1 gram of total crude drug per milliliter.

Embodiment 3

[0032] Example 3: 255 parts of Rhizome, 65 parts of Sophora flavescens, 85 parts of Asparagus, 45 parts of dark plum, and 35 parts of Asarum, all of which are dry products. Weigh the Chinese medicinal materials according to the weight ratio of the raw materials, soak Asarum separately with 1 times the weight of water, and put the other four kinds (shengbaibu, flavescens, asparagus, and dark plum) together in a large pot with 1 times the weight of water Soak for 1 hour; add 8 times the total weight of all raw materials in proportion to decoct, boil and continue to decoct for 60 minutes, then add asarum (together with soaking water) and decoct for 6 minutes; filter to remove slag, and the obtained water The extract is the pollution-free pesticide of pure traditional Chinese medicine components. Finally, the obtained water extract is concentrated to contain 1 gram of total crude drug per milliliter.

Abstract

The invention provides a non-polluted pesticide with pure traditional Chinese medicinal components. The pesticide is prepared from the following raw materials: raw radix stemonae, radix sophorae flavescentis, asparagus fern, smoked plum and asarum, wherein the raw materials are dried materials. The non-polluted pesticide with pure traditional Chinese medicinal components is prepared from human available traditional Chinese medicinal herbs serving as raw materials, is simple in components, good in compatible action, simple in preparation method, does not have toxic or harmful effect, pollution or residues on crops, does not pollute the environment, and has the advantages of high efficiency, quick response, long drug effect duration and wide pesticide range; effective components of the non-polluted pesticide have a killing effect to insect pests, are not toxic to human bodies, and have the effect of preventing diseases for crops; components in soil can kill insect pests in the soil, and can be used as fertility of crop growth. By adopting the non-polluted pesticide, the insect pests killed by the pesticide cannot cause secondary hazard to natural enemies of the insect pests, and components flowing into water cannot pollute the water source or poison aquatic lives, so that the natural environment and ecological balance can be facilitated. The invention also provides a method for preparing the pesticide and a method applied to crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pollution-free pesticide with pure traditional Chinese medicine components and a preparation method thereof. It also relates to the application of pollution-free pesticides with pure traditional Chinese medicine components. Background technique [0002] my country is a large agricultural country with a large population, and it is also a large country in the production and use of pesticides. It is necessary to produce a large amount of pesticides every year to prevent and control pests and diseases of vegetables, fruits and other crops. Due to the continuous use of chemically synthesized pesticides in large quantities over the years, pest species have developed resistance to pesticides, and the amount and frequency of pesticide use have also increased, resulting in a vicious circle. A large number of lost pesticides volatilize into the air, flow into water source...
