Abstract

The invention relates to a pesticide composition containing extracts of veratrum nigrum and mamee-apple and a preparation method and application of the pesticide combination and belongs to the field of pesticides. Active components of the pesticide composition containing the extracts of the veratrum nigrum and the mamee-apple are obtained by extracting the following raw medicinal materials in parts by weight: 1 part of the veratrum nigrum and 0.5-6 parts of the mamee-apple. The active components of the pesticide composition are obtained by mixing the veratrum nigrum and the mamee-apple and then extracting the mixture or obtained by independently extracting the veratrum nigrum to obtain a veratrum nigrum extract, independently extracting the mamee-apple to obtain a mamee-apple extract and then mixing the two extracts. The pesticide composition containing the extracts of the veratrum nigrum and the mamee-apple has an obvious effect of preventing and treating homoptera, lepidoptera and acarina pests and has a positive significance for the agricultural production.

Description

technical field [0001] The invention relates to a pesticide composition containing veratrum and mami apricot extracts, a preparation method and an application, 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 become one of th...
