Problems solved by technology

At the same time, when chemical pesticides and fungicides are used, various plant pathogenic bacteria will develop drug resistance and drug resistance, which will increase the difficulty of control and even cause control failure
In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective
Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants

Abstract

A natural bactericide for prevention and treatment of peach brown rot is provided. The natural bactericide is prepared from the following components: balsam pear, phragmites australis, radix puerariae, aristolochia debilis, rhizoma atractylodis macrocephalae, polygonum cuspidatum, java brucea fruit, pogostemon cablin, belamcanda chinensis, and pyrola rotundifolia. The natural bactericide for prevention and treatment of peach brown rot has rich raw material sources, and is low in cost; and the natural bactericide is prepared by the pure natural components, so that the natural bactericide not only is non-toxic and pollution-free, but also can effectively prevent and treat peach brown rot.

Description

Technical field [0001] The invention belongs to the field of preventing and controlling diseases and insect pests, and particularly relates to a natural fungicide for preventing and treating brown rot of peach trees and a preparation method thereof. Background technique [0002] Peach brown rot, also known as sclerotinia disease and fruit rot, is an important fruit disease of peach trees. The symptom of peach tree brown rot is mainly damage to peach fruit, and secondly it can damage flowers, leaves and new shoots. Fruits can be damaged from young to mature fruit, but the closer they mature, the heavier the damage. The fruit is diseased, and small brown round spots appear on the fruit surface at first. If the conditions are right, the diseased spots will spread to the whole fruit within a few days, and the flesh of the fruit will also brown and soft rot, and finally gray-brown mold will grow on the surface of the diseased spots. Cluster, that is, the conidia layer of the pathoge...
