Abstract
The invention relates to a pesticide composition containing lightyellow sophora root and veratrum nigrum extracts, and a preparation method and application thereof, and belongs to the field of pesticides. In order to solve technical problems, the invention provides the pesticide composition containing the lightyellow sophora root and veratrum nigrum extracts, and the preparation method and application thereof. According to the pesticide composition containing the lightyellow sophora root and veratrum nigrum extracts, active ingredients of the pesticide composition are prepared by extracting 1 weight part of lightyellow sophora root and 0.5 to 8 weight parts of veratrum nigrum together; furthermore, the active ingredients are prepared by extracting the lightyellow sophora root and the veratrum nigrum together through an ethanol solution. The pesticide composition containing the lightyellow sophora root and veratrum nigrum extracts is prepared by mixing the lightyellow sophora root and the veratrum nigrum and extracting together, the content of total alkaloids is greatly increased, and the pesticide composition can well kill Homoptera pests such as aphid, scale insect and whitefly, and Hemiptera pests such as green plant bug, so the pesticide composition has positive significance for agricultural production.
