| Abstract: | Soybean root rot is one of the major soybean diseases. It could be controlled by some microorganism effectively. In order to ealuate the effect of fungi and bacteria mixture preparation against soybean root rot, soybean growth and yeild, randomized block test was conducted in field. The result showed that emergence of soybean seedlings was promoted by the biocontrol preparation, dry weight was accumulated and leaf area index was increased, nitrogen fixation ability of root nodule was strengthened. The control effect of soybean root rot were 37. 5% and 58. 74% in 2006 and 2007, soybean yield were increased by 5.43% and 25.86%, respectively. |
