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

Description

technical field [0001] The invention belongs to the field of preventing and controlling diseases and insect pests, and in particular relates to a natural fungicide for preventing and controlling peach tree brown rot and a preparation method thereof. Background technique [0002] Peach tree brown rot, also known as sclerotinia and fruit rot, is an important fruit disease of peach trees. The symptoms of peach tree brown rot mainly damage peach fruit, and secondly, it can also damage flowers, leaves and new shoots. The fruit can be damaged from young fruit to mature fruit, but the closer to maturity, the more serious the damage. When the fruit gets sick, small brown circular spots will appear on the surface of the fruit at first. If the conditions are suitable, the diseased spots will spread to the whole fruit within a few days, and the pulp will also turn brown and soft rot. Finally, gray-brown mold will appear on the surface of the diseased spots. Cluster, the conidium laye...
