Abstract：Bacterial fruit blotch (BFB) of cucurbits is serious seed-borne diseases,seed treatment is an effective measure to avoid the occurrence of seed and seedling diseases prevention and control.The effective chemical for preventing and controlling bacterial fruit blotch were tested.Nine kinds of new bactericides (BX6,"JiuCuTong"etc),and 8 kinds of commonly used bactericides (3％ Tethiamethoxam,hydrogen peroxide,etc) were tested.The bacteriostatic effect of these chemicals were compared by used with tablet bacteriostatic circle method.The effects on the incidence and growth of seedlings of melon inoculated seeds treated with 5 chemicals were observed and compared.In the tablet bacteriostatic experiment,peracetic acid (1 ∶ 50) is the best of bacteriostatic effect,the rest in turn is 30％ hydrogen peroxide (1 ∶ 50),BX6 (stock solution),"XIAOJIATONG" (1 ∶ 50),"JiuCuTong" (stock),Tsunami (1 ∶ 50).on the whole,the test results of 5 chemicals treatment in the control effect,seed germination rate and seedling growth,it showed that chemical BX6 (stock solution) treated for 20-30 min was the best in the control effect,reached 72.2％-78.8％,followed by peracetic acid (1 ∶ 50) treatment for 20-30 min,with 71.5％-72.2％ efficacy,hydrogen peroxide (1 ∶ 50) treatment for 30min,the with 71.5％ efficacy.The results showed that the BX6,peracetic acid,hydrogen peroxide 3 kinds of bactericides had better effect of preventing disease,and could be considered as the seed treatment agent to control the bacterial fruit blotch.
