Abstract

The invention relates to a pesticide composition containing myristica fragrans and coptis chinensis extract and a preparation method and application of the pesticide composition, and belongs to the field of pesticide. The technical aim of providing the pesticide composition containing myristica fragrans and coptis chinensis extract is achieved. The pesticide composition containing myristica fragrans and coptis chinensis extract is prepared from, by weight, the active ingredients of 10-30 parts of myristica fragrans and 1 part of coptis chinensis. The common extract of myristica fragrans and coptis chinensis has the synergistic interaction function, and has the obvious preventing and treating effect on crop apple ring spots. The pesticide composition can be extracted from myristica fragrans and coptis chinensis together, the content of nutmeg ether, berberine and other sterilization active ingredients, the same as nutmeg ether and berberine, of main groups is increased, the immune system capacity of crops can be improved while the apple ring spots are prevented and treated, and the activity of the pesticide composition can be remarkably improved. Chinese herbal medicine can be adopted as raw materials, and therefore the problem of pesticide residues is avoided. Compared with pesticide independently adopting a chemical source, environment friendliness is achieved. In the use process, effective concentration is low, and cost is low.

Description

technical field [0001] The invention relates to a pesticide composition containing extracts of nutmeg and coptis chinensis, a preparation method and application thereof, and belongs to the field of pesticides.
