Wild rice fungal endophyte Falciphora oryzae could induce resistance to rice blast under laboratory conditions. In order to determine the control efficiency of Falciphora oryzae to rice blast of direct seeding rice, a field experiment was carried out in 2017 at Tonglu, Zhejiang. The results showed that the control efficiency of Falciphora oryzae treated in different periods to rice blast of direct seedling rice was equivalent to bioreagents Kasugamycin and Bacillus, there was no significant difference between different treatments. Among them, the control efficiency by seed dressing (0 d), 7 d or 14 d after sowing to leaf blast reached above 70%. The control efficency of Falciphora oryzae by 7 d or 14 d after sowing to neck blast reached above 70%, too. Thus it can be seen that seed dressing or sowing treatment once was capable to control rice blast of direct seeding rice.
