Problems solved by technology

[0006] (1) The application of existing chemical pesticides in the apple planting process: spraying before the apples germinate in spring, this treatment method is not ideal for the control of pests born after the apples germinate, and the pertinence is not strong;
[0007] Application in the corn planting process: Spray after the emergence of corn, this treatment method is not ideal for the control of pests in the corn field, and the pertinence is not strong;
[0008] (2) Existing chemical pesticides are applied to apples and corns to control pests, which have certain side effects on apples and corns, are poor in safety, and have a certain inhibitory effect on their growth, thereby reducing crop yields;
[0009] (3) Existing chemical pesticides only have control effects on apple and corn pests, but have no effect on apple and corn diseases

Abstract

The invention relates to a botanical pesticide .The botanical pesticide comprises, by weight, 11-15 parts of diafenthiuron, 26-30 parts of organic solvent, 11-15 parts of emulgator, 2-6 parts of thickening agent, 3-6 parts of antifreezing agent, 36-40 parts of water, 1-2 parts of sophora flower bud extract, 0.5-1 part of polyoxin, 1-2 parts of coptisine and 0.5-1 part of sodium nitrate .A preparing method of the botanical pesticide is characterized by including the following steps that the sophora flower bud extract is prepared; weighing is carried out; mixing is carried out .The botanical pesticide has the high control effect on spider mites, aphids, scale insects and thrips, is free of any side effect and high in safety, has the obvious increasing effect on the yield of apples and corn, has the obvious improving effect on the quality of apple products and corn products and can effectively prevent apple diseases and corn diseases.

Description

technical field [0001] The present invention relates to a plant-derived pesticide, in particular to a plant-derived pesticide and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] In a broad sense, Sophora japonica L. is the dried flower buds and flowers of Sophora japonica L., a leguminous plant. It is produced in various regions of China, mostly in the Loess Plateau and the North China Plain. In summer, the flower buds are harvested when the flowers are not in bloom, which is called "Sophia japonica rice"; After harvesting, remove the branches, stems and impurities of the inflorescences, dry them in time, and use them raw, fried or fried with charcoal. [0003] The existing chemical pesticides have a certain degree of toxicity and side effects on crops, and will cause environmental pollution such as land and water sources to varying degrees. Improper use of pesticides will cause phytotoxicity of crops, lead to abn...
