Abstract:
Strain Sneb207 was isolated from soybean nodule and identified as Bacillus megaterium.It is proved the fermentation filtrate，even the sterilized fermentation filtrate of Sneb207 could promote soybean seedlings growth significantly.The virulence effect of Sneb207 fermentation filtrate to different nematodes was tested.The result indicated Sneb207 had poisonous effect to nematodes.And significant virulence to different nematodes was detected，the sequence of virulence from high to lower was Heterodera glycines，Meloidogyne hapla，Aphelenchiodes besseyi，Ditylenchus destructor.The virulence of different concentrations of Sneb207 fermentation filtrate to Heterodera glycines was also tested.It proved bacteria Sneb207 was an effective biological agent to control soybean cyst nematode (SCN) and promote soybean growth.
