| Abstract: | The antagonistic substance, isolated from the culture of Bacillus subtilis XF-1 by a method of hydrochloric acid precipitation conbined with methanol extraction substance, could inhibit 50% resting spore activity of Plasmodiophora brassicae treated for 2 d and over 90% spore germination treated for 9 d. The inhibition rates were 71.97%, 62.23%, 60.96%, 60.70% and 57.92% of the plant pathogens, i.e. Fusarium solani, Rhizoctonia solani, F. graminearum, F. solani, and Alternaria alternate, respectively. |
| Keywords: | Bacillus subtilis XF-1 Plasmodiophora brassicae antagonistic substance inhibition effect |
