Technical Abstract:
Deleterious rhizobacteria (DRB) colonize the rhizosphere and suppress plant growth. The mechanisms of plant suppression are as varied as the organisms themselves and can include the production of phytotoxic substances, nutrient competition, or interactions with plant growth promoting microbes in the rhizosphere. DRBs are a group of pathogens that have often been overlooked, because of their subtle effect on plant growth. Their colonization and inhibition is often found to be species or variety specific. Root exudates may play a part in some plant - DRB interactions. These organisms can influence the distribution, abundance, and competition among plant species. DRBs have been studied for use in pest management systems. It is imperative to develop an understanding of these soil microbes and their ecology in the rhizosphere, so that they can be effectively managed to benefit agriculture and the environment.
