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.
