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 loquat canker and a preparation method thereof. Background technique [0002] Loquat, aliases: Luju, Jinwan, Luzhi, Rosaceae, Loquat plant, loquat is native to southeast China, named for its leaf shape resembling a pipa musical instrument, and its flowers can be used as medicine. The height of the tree is 3 to 5 meters. The leaves are large and long, thick and hairy, oblong, and shaped like a lute. Another name is Luju, Luzhi, Jinwan, Yanguo, Jiaozi. Unlike most fruit trees, loquat blooms in autumn or early winter, and its fruit matures in spring to early summer, earlier than other fruits. Therefore, it is called "the one with the unique spirit of the four seasons among fruit trees". The flower of loquat is white or light yellow, has five petals, about 2 centimeters in diameter, forms a bunch wit...
