preparation example Construction

[0048] Further, the present invention also discloses a preparation method of the pesticide composition containing Sophora flavescens and tobacco extract, comprising the following steps:

[0049] a. Extraction: Weigh Sophora flavescens granules and tobacco granules, mix them, add ethanol solution according to the ratio of material to liquid 1:3~12g / ml, extract under reflux at 60~85°C, filter, and obtain the extract solution; wherein, the concentration of ethanol solution≥ 60% v / v;

[0050] b. Preparation: make the extract into microemulsion, soluble agent or aqueous agent.

[0051] Wherein, Sophora flavescens granules and tobacco granules can be commercially available granules, or can be obtained by pulverizing Sophora flavescens root and whole tobacco herb by conventional methods. In order to improve the extraction effect and save cost, the flavescens granules and tobacco granules can be passed through a 60-100 mesh sieve, preferably 80 mesh sieve.

Abstract

The invention relates to a pesticide composition containing sophora flavescens and tobacco extracts as well as a preparation method and an application thereof, belonging to the field of pesticides. The active ingredients of the pesticide composition are jointly extracted from the following crude drugs in parts by weight: 1 part of sophora flavescens and 0.2-4 parts of tobaccos. Further, the active ingredients of the pesticide composition are extracted from sophora flavescens and the tobaccos jointly with an ethanol solution. The pesticide composition containing sophora flavescens and tobacco extracts has the beneficial effects that sophora flavescens and the tobaccos are mixed and then jointly extracted, so that the content of total alkaloids is substantially increased and homoptera pests such as aphids, coccids and whiteflies as well as hemiptera pests such as lygus lucorum and the like can be well killed; and therefore the pesticide composition has positive significance for agricultural production.
