The invention belongs to the technical field of corn disease and insect prevention and treatment and particularly relates to a method used for prevention and treatment of a premature leaf spot disease at the later growth stage of corn. The method used for prevention and treatment of the premature leaf spot disease at the later growth stage of the corn includes the steps that 1, in first-time chemical application, at the big trumpet period of the corn, a mixed solution of1000-2000 times of 18.7% propiconazole.azoxystrobin SC and 800-1000 times of 40% chlorantraniliprole.thiamethoxam WDG is applied once; 2, in second-time chemical application, 7-10 days after first-time chemical application, a mixed solution of 1000-2000 times of 50% kresoxim-methyl WP and 800-1000 times of 40% chlorantraniliprole.thiamethoxam WDG is applied once. The low-concentration mixed solution of Quilt plus Virtako or kresoxim-methyl plus Virtako is adopted, and therefore the forward method is good in safety for corn and has excellent ef
