Abstract

The invention relates to a pesticide composition containing black false hellebore and acorus calamus extracts as well as a preparation method and an application, belonging to the field of pesticides. The active ingredients of the pesticide composition are extracted from the following crude drugs in parts by weight: 1 part of black false hellebore and 0.5-6 parts of acorus calamus. The active ingredients can be extracted from the crude drugs black false hellebore and acorus calamus jointly after black false hellebore and acorus calamus are mixed and can be also prepared by firstly extracting black false hellebore extracts from black false hellebore independently and extracting acorus calamus extracts from acorus calamus independently and then mixing the two kinds of extracts. The pesticide composition containing black false hellebore and acorus calamus extracts has obvious control effects on homoptera and acarina pests and has positive significance for agricultural production.

Description

technical field [0001] The invention relates to a pesticide composition containing extracts of veratrum and calamus calamus, a preparation method and application thereof, and belongs to the field of pesticides. Background technique [0002] In recent years, in the field of agriculture and forestry, due to single and unscientific use of drugs, plant diseases and insect pests have developed resistance to varying degrees, while chemical pesticides are still used as the main control species in agricultural and forestry production, causing environmental pollution and ecological environment. With the improvement of people's living standards and the enhancement of health awareness, the research and development of biopesticides is gradually attracting the attention of pesticide research and development workers, and has become a hot spot for the sustainable development of agriculture and forestry. An effective way to improve drug efficacy. Among them, botanical pesticides have becom...
