| 中文摘要: |
| 巨大芽孢杆菌（Bacillus megaterium）B196 菌株产生的Iturin A2 对水稻纹枯病菌具有较强的抑制作用，
其抑菌中浓度为39.5621 滋g/mL；在浓度为160 滋g/mL 下，Iturin A2 对水稻纹枯病的离体、盆栽和大田防效分别为
100%、85.31%和84.42%，显著高于5%井冈霉素水剂有效成分为200 滋g/mL 的防效。 |
| 英文摘要: |
| The Iturin A2 produced by Bacillus megaterium strain B196 could inhibit the growth of Rhizoctonia solani.
The median effect concentration (EC50) of Iturin A2 on R. solani was 39.5621 滋g/mL. The control efficacy of Iturin A2 at
the concentration of 160 滋g/mL on the rice sheath blight caused by R. solani was 100%, 85.31% and 84.42% in vitro, in
pot and in field, respectively. This efficacy was higher than that of 5% jinggangmycin at the concentration of 200 滋g/mL. |
