Abstract:
By using enrichment media NPC and CVP, 792 strains of Pseudomonas and 515 strains of Erwinia were isolated from the rhizosphere of Digitaria adscendens (H. B. K.) Hem and Setaria vindis (L.) Beanv. Following which, experiments of antimetabolic test with E. coli, seed emergence controlling of S. viridis, herbicidal activity and security with green grass were carried out to select the desired bacteria. As the result, the selected strain, S7, could wholly control the seed emergence of S. viridis without any harm to the two tested green grass. And more, S7 promoted the seed emergence of Festuca arundinacea slightly. In spite of the comparatively low corrected mortality (56. 7%) of S7 after emergence of S. viridis, Selecting of microbial herbicides from weed DRB is thought to be more prospective.
