Abstract

The invention relates to the field of pesticides, in particular to a pesticide containing potato and derris elliptica extracts, and a preparation method and application thereof. Active ingredients of the pesticide containing the potato and derris elliptica extracts are extracted from 1 weight part of potato and 1 to 8 weight parts of derris elliptica. The pesticide containing the potato and derris elliptica extracts has a synergistic effect, has an obvious effect of controlling Homoptera and Lepidoptera pests, can strengthen immune systems of plants while quickly killing the pests, and can obviously improve plant vitality; the pesticide is prepared from Chinese herbal medicines, so the problem of pesticide residue is solved and the pests hardly generate resistance; during use, the effective concentration is low and the cost is low.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide containing extracts of potato and derina dermatitis and its preparation method and application. 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 the ...
