| Abstract: | Biological control microorganism was isolated from pathogenic soil of linseed.Inhibition rates to Fusarium oxysporum f.sp.lini were evaluated using 151 fungus isolates from different provinces.A bacterial XJ2-20 from 21 antagonistic Bacillus strains showed strong antagonistic effect on the 151 fungus isolates.Its highest inhibition rate was 64.5%.Fermentation filtrate of XJ2-20 affected mycelium growth and spore bourgeoning.Its efficiency of control was as high as 56.3% in pot experiment.Optimized fermentat... |
