Abstract:: Muskmelon and edible seed watermelon were used as the test materials，and 2 kinds of new fungicides(BX6，Jiucutong) and 3 kinds of antibacterial agents(Tsunami，peracetic acid and hydrogen peroxide) were prepared.Two treatment methods were adopted with bactericide spraying firstly on the seedlings then inoculation of bacterial fruit blotch(BFB)，and after inoculating bacteria on the seedlings then bactericide spraying，the incidence rate and control efficacy of the seedlings after chemical treatment were investigated in order to supply reference for prevention of bacterial fruit blotch.The results showed that hydrogen peroxide (1∶25)，had a good antibacterial effects on muskmelon and edible seed watermelon seedling，and showed both protective and curative effects;the control efficacy was up to 87.4%，84.5% and 60.5%,74.5%,respectively;Tsunami(1∶25-1∶75)，peracetic acid (1∶25-1∶50)，had better protective effect both on muskmelon and edible seed watermelon seedling;the maximum of control efficacy was up to 78.3%，80.4% and 63.5%，81.6%,respectively；BX6 (1∶8) had better curative effect on muskmelon and edible seed watermelon seedling.And they were 61.3% and 66.9%。
