The invention mainly relates to the technical field of planting and discloses a prevention and treatment method of a
monstera deliciosa leaf spot disease. The method comprises the steps of
seed treatment, germ prevention and treatment, and illumination
cutting; the method is simple, seed propagation is used, pathogenic microorganisms carried are reduced significantly, and the
disease occurrence rate is reduced; seeds are soaked with
wine solution and are mixed with a seed-dressing agent, the
dormancy is broken, the germ activity is enhanced, the pathogenic microorganisms are reduced, the
disease resistance of germs is enhanced to make the
germination rate reach 98%, after seeding, the germinating time is decreased by 5-6 days, the seed-dressing agent component source is extensive, and the cost is low;
antibacterial agent solution is regularly sprayed to increase nutrients, various pathogenic microorganisms are killed, the disease resistance to
monstera deliciosa is enhanced, and the occurrence of various diseases is reduced; the
illuminance of the
monstera deliciosa is regularly enhanced, the
leaf number is reduced, and therefore the
nutrient absorption of the monstera deliciosa can be promoted, the
stress resistance is enhanced, the germ infectious rate between leaves is reduced, the
disease occurrence is reduced, the occurrence rate of soft rot is decreased to 3%, and the
economic income is increased by 11.3%.
