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, in particular to a natural fungicide for preventing and treating strawberry leaf blight and a preparation method thereof. Background technique [0002] Strawberry leaf blight, also known as purple spot and scorch, is relatively common in my country and is one of the common diseases of strawberry leaves. Sometimes the damage is quite serious. The pathogen of strawberry leaf blight is Marssonina potentillae (Desmazieres) Magn, and the sexual stage is Diplocarpon earliana (Ellet EV.), which belongs to Ascomycota subphylum. The fungus overwinters on plant diseased tissues or fallen diseased residues with ascus or pycnidium, and releases ascospores or conidia in spring to spread through the air and infect the disease, and the diseased seedlings carry out medium and long-distance distance spread. This disease is a low-temperature disease, and the weather with more r...
