Description

technical field [0001] The invention relates to the field of prevention and treatment of fruit diseases. Background technique [0002] Macular disease is also known as lipid spot macular disease, lipid spot disease, and brown small round star disease. Dozens or hundreds of diseased spots can grow on one leaf of the damaged plant, which hinders the photosynthesis of the leaves, weakens the tree vigor, causes a large number of fallen leaves, and affects the yield to a certain extent. After the damage, the shoots of the branches shrank and did not grow long, which affected the expansion of the crown; after the fruit was damaged, a large number of oil tumor stains were produced, which affected the commerciality of the fruit. Contents of the invention [0003] The invention aims to solve the deficiency in the prevention and treatment technology of the navel orange macular disease at present, and invents a technology for the prevention and treatment of the navel orange macular ...
