Bacterial fruit blotch (BFB) caused by Acidovorax avenae subsp. citrulli is defective disease to watermelon cultivated areas. To control of BFB, we investigated control efficiency to use commercial antibacterial pesticides. Growth inhibition zone on medium were formed as oxolinic acid WP and oxytetracycline WP. Control efficacy of four anti-bacterial pesticides on seed and seedling stage were performed. As a results, oxytetracyclin WP is shown over 90% control efficiency on seed and acibenzolar-S-methyl + mancozeb WP shown over 90% control efficiency on seedling stage Hot-water treatment method could be possible to reduced infection rate on seed. The conditions of hot-water treatments are $50{\sim}55^{\circ}C$ on 20~30 minutes. These results suggested that the methods were helpful watermelon seedling nursery to control of the bacterial fruit blotch by A. avenae subsp. citrulli.
