Using bacteria to control annual cropping weeds

摘要

Deleterious rhizobacteria (DRB) previously isolated from USA soils and demonstrated to suppress growth of various weeds of USA cropping systems were tested against several important weed and crop species from Western Australia. Some DRB from USA weresuccessful in reducing the growth of some weed species from Australia. They also however, reduced the growth of some major Australian canola varieties. It is recommended that these USA isolates not be used in Western Australia but instead Australian DRBshould be isolated and tested for their specificity to Australian weeds, crops and conditions.
