Abstract

The invention relates to a natural inhibition agent for chrysanthemum root rot diseases and a preparation method thereof, and belongs to the field of plant source preparation sterilization. The commonuse traditional Chinese medical materials of folium artemisiae argyi are ground into powder; then, an ethanol solution is used as an extraction agent; twice heating ethanol extraction, concentration,and freeze drying are performed to obtain powdery extracts; the powdery extracts are diluted for proper times; then, root irrigation or spraying application is performed. By using the technical scheme, the natural inhibition agent can be used for effectively preventing and treating the chrysanthemum root rot diseases; the advantages of low cost, high safety, high efficiency, no pesticide residue,no heavy metal pollution and the like are realized; the environment-friendly effects are achieved on soil and ecological environments; the characteristics of ecological and environment-friendly effects are achieved; an effective path is provided for the green ecological culture of chrysanthemum.

Description

technical field [0001] The invention belongs to the field of bactericidal plant source preparations, in particular to a natural inhibitor for effectively preventing and treating chrysanthemum root rot and a preparation method thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
