The control effects of eight seed coating agents on diseases and pests in maize seedling stage were compared, and the use safety was identified to provide the scientific basis for the choice of seed coating agents. The results showed that the effect of imidacloprid +thiram +pencycuron on underground pests was better, that of fipronil on leaf pests was better, and that of imidacloprid +thiram +pencycuron +AHS100 on rough dwarf virus disease was better. The effects of beta-cypermethrin imidacloprid +pencycuron +AHS100 and vitavax200FF on root rot were better. The comprehensive control effects of beta-cypermethrin imidacloprid + pencycuron +AHS100, carbofuran +tebuconazole, fipronil and imidacloprid+thiram+pencycuron were better. All of the seed coating agents were safe, which could increase the emergence rate and vegetative growth in seedling stage.
