Title: Evaluation of Biocontrol Efficiency and Security of A Bacillus Subtilis Strain B29 Against Cucumber Fusarium wilt in Field
Abstract: Bacillus subtilis strain B29,against Fusarium oxysporum f.sp.Cucumerinum,was isolated from cucumber rhizosphere.After twice of 4-field-plots experiments,the control efficiencies of 100,250,and 500 dilution times to cucumber Fusarium wilt were 70.3 %-88.2 %,62.3 %-85.9 %,and 54.7 %-80.6 %,respectively.The average efficiency of field trials with B29 was 84.9 % during 2 years and the yield of cucumber increased 12.57 %.The acute toxicity of Bacillus subtilis strain B29 to big mouse through its mouth and skin was examined,and the LD50 was beyond 5 000 mg·kg-1.The strain B29 to the seedling rate,growth and development with 4 major crops(cucumber,tomato,bean,and seed pumpkin)was safe.
