Embodiment 1

[0020] The present invention is formed by mixing the components of the following weight percentage ratios:

[0021] Nicotine 2%, wild mugwort oil 2%, camphor leaf oil 3%, litsea cubeba oil 5%, Sophora flavescens mixed ethanol extract 30%, Junzi mixed water extract 10%, emulsifier 15%, twelve Sodium alkyl sulfonate 1%, the balance is water; wherein said sophora flavescens mixed ethanol extract is after the plant raw material of following parts by weight is extracted by mass percentage 70% ethanol solution, obtains relative density and is 1.02 extract : 3 parts of Sophora flavescens, 1 part of Tripterygium wilfordii, 2 parts of Toosendan, 2 parts of Veratrum, 2 parts of Aconitum, 1 part of Fructus Cnidii, 1 part of camphor seed; Parts by weight of the plant raw materials are extracted with an aqueous solution to obtain an extract with a relative density of 1.05: 1 part of Senecio, 1 part of Zanthoxylum bungeanum, and 2 parts of Shijunzi.

Embodiment 2

[0023] It is formed by mixing the following components by weight percentage:

[0024] Nicotine 5%, wild mugwort oil 5%, camphor leaf oil 8%, litsea cubeba oil 10%, Sophora flavescens mixed ethanol extract 40%, Junzi mixed water extract 15%, emulsifier 20%, twelve Sodium alkyl sulfonate 2%, the balance is water; wherein said sophora flavescens mixed ethanol extract is after extracting the plant raw materials of the following parts by weight through a 70% ethanol solution by mass percentage to obtain an extract with a relative density of 1.05 : 3 parts of Sophora flavescens, 1 part of Tripterygium wilfordii, 2 parts of Toosendan, 2 parts of Veratrum, 2 parts of Aconitum, 1 part of Fructus Cnidii, 1 part of camphor seed; Parts by weight of the plant raw materials are extracted with an aqueous solution to obtain an extract with a relative density of 1.05: 1 part of Senecio, 1 part of Zanthoxylum bungeanum, and 2 parts of Shijunzi.

Embodiment 3

[0026] It is formed by mixing the following components by weight percentage:

[0027] Nicotine 3%, wild mugwort oil 3%, camphor leaf oil 5%, litsea cubeba oil 8%, Sophora flavescens mixed ethanol extract 36%, Junzi mixed water extract 12%, emulsifier 16%, twelve 1% sodium alkyl sulfonate, the balance is water; wherein the mixed ethanol extract of Sophora flavescens is obtained by extracting the following plant raw materials with a mass percentage of 70% ethanol solution to obtain an extract with a relative density of 1.10 : 3 parts of Sophora flavescens, 1 part of Tripterygium wilfordii, 2 parts of Toosendan, 2 parts of Veratrum, 2 parts of Aconitum, 1 part of Fructus Cnidii, 1 part of camphor seed; Parts by weight of the plant raw materials are extracted with an aqueous solution to obtain an extract with a relative density of 1.10: 1 part of Senecio, 1 part of Zanthoxylum bungeanum, and 2 parts of Shijunzi.

Abstract

The invention relates to a compound plant-derived pesticide, which is prepared by mixing the following components in percentage by weight: 2-5% of nicotine, 2-5% of wild mugwort oil, 3-8% of cinnamon leaf oil, 5-10% of litsea cubeba oil, 30-40% of flavescent sophora root mixed ethanol extract, 10-15% of Rangoon creeper fruit mixed water extract, 15-20% of emulsifying agent, 1-2% of sodium dodecylsulfate and the balance of water, wherein the flavescent sophora root mixed ethanol extract is obtained by extracting 3 parts by weight of flavescent sophora root, 1 part by weight of triperygium wilfordii, 2 parts by weight of toosendan fruit, 2 parts by weight of hellebore, 2 parts by weight of szechuan aconite, 1 part by weight of cnidium fruit and 1 part by weight of camphor tree seed with 70wt% ethanol solution, and has the relative density of 1.02-1.10; and the Rangoon creeper fruit mixed water extract is obtained by extracting 1 parts by weight of groundsel and 2 parts by weight of Rangoon creeper fruit with water solution, and has the relative density of 1.02-1.10. The compound plant-derived pesticide overcomes the limitations that the most plant derived pesticides are single in pest-killing components and simple in action mechanism, improves the comprehensive prevention and control effect, is quick in acting and long in duration, and avoids the generation of pest pesticide resistance.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a compound botanical pesticide and a preparation method thereof. Background technique [0002] Most of the pesticides used at home and abroad are chemical pesticides. When chemical pesticides are used to control crop pests, they have the characteristics of less dosage, quick results, and good insecticidal effects. However, during the use of chemical pesticides, they have caused serious negative impacts on humans and the ecological environment. It is easy to cause poisoning during use; the medicament is not easy to degrade, pollutes the environment, and is easy to remain in crops; the medicament has poor selectivity, kills natural enemies and non-target organisms, and is unsafe for humans and animals; pests are prone to develop drug resistance, and the control effect is reduced. With the development of society and the advancement of science and technology, the vario...
