Problems solved by technology

[0002] Due to the long-term dependence of human beings on a single type of insecticide, pests are prone to develop resistance, resulting in a sharp increase in the use of chemical insecticides, which not only increases the economic burden on farmers, but also causes pollution to the environment and agricultural products. Currently, there are a large number of compound insecticides on the market. Insecticides, but most of them are mixed with chemical pesticides, which are very harmful to humans and animals and are easy to cause pollution. Moreover, after a long period of use, pests will develop resistance to them

Embodiment 1

[0019] A compound pesticide, which is an emulsifiable concentrate prepared by compounding neem extract and matrine total alkaloids as medicinal components. It also contains a variety of auxiliary agents, specifically 5wt% surfactant, 1.2wt% sunscreen, 1.0wt% stabilizer, 1.0wt% preservative, 0.5wt% synergist, 0.1wt% pH regulator, The balance is organic solvent. Wherein the neem extract content is 1wt%, and the total alkaloid content of Sophora flavescens is 0.01wt%. The surfactant is selected from sorbitol in nonionic polyoxyethylene ethers; the sunscreen is selected from p-aminobenzoic acid; the stabilizer is selected from epoxidized vegetable oil; the preservative is selected from aminobenzoic acid; The effect agent is selected from soybean meal; the pH regulator is selected from sodium hydroxide; the organic solvent is selected from ethanol.

Embodiment 2

[0021] A compound pesticide, which is an emulsifiable concentrate prepared by compounding neem extract and matrine total alkaloids as medicinal components. It also contains a variety of auxiliary agents, specifically 6wt% surfactant, 1.4wt% sunscreen, 1.2wt% stabilizer, 1.0wt% preservative, 0.6wt% synergist, 0.1wt% pH regulator, The balance is organic solvent. Wherein the neem extract content is 2wt%, and the total alkaloid content of Sophora flavescens is 0.02wt%. The surfactant is selected from non-ionic Tween-20; the sunscreen is selected from castor oil; the stabilizer is selected from 2,6-di-tert-butyl p-phenol; the preservative is selected from aminobenzoic acid; selected from chlorinated fats; pH regulators selected from sodium hydroxide; organic solvents selected from ethanol.

Embodiment 3

[0023] A compound pesticide, which is an emulsifiable concentrate prepared by compounding neem extract and matrine total alkaloids as medicinal components. It also contains a variety of auxiliary agents, specifically 7wt% surfactant, 1.8wt% sunscreen, 1.6wt% stabilizer, 1.0wt% preservative, 1.0wt% synergist, 0.1wt% pH regulator, The balance is organic solvent. Wherein the neem extract content is 5wt%, and the total alkaloid content of Sophora flavescens is 0.02wt%. The surfactant is selected from non-ionic Tween-80; the sunscreen is selected from castor oil; the stabilizer is selected from 2,6-di-tert-butyl p-phenol; the preservative is selected from aminobenzoic acid; selected from chlorinated fats; pH regulators selected from potassium hydroxide; organic solvents selected from acetone.

Abstract

The invention relates to a compound pesticide, in particular to a pesticide prepared by compounding azadirachta indica extracts and total matrines, belonging to the technical field of biopesticide preparation. The compound pesticide is characterized in that the compound pesticide is prepared by compounding the active ingredients such as azadirachta indica extracts and total matrines, wherein the mass ratio of the azadirachta indica extracts to the total matrines is (1-10):(0.01-1). The compound pesticide has the following beneficial effects: the compound pesticide is prepared by using the azadirachta indica extracts and total matrines as the active ingredients and then adding certain amount of auxiliaries; the compound pesticide is not a chemical drug, thus being environmentally-friendly; the pharmacodynamics experiments prove that the compound pesticide has good pesticidal effect; and because the active ingredients of the drug belong to the natural drugs, the pests are not easy to have drug resistance.
