AI Technical Summary
In complex soil micro-ecosystems, single beneficial strains are difficult to colonize stably, resulting in unstable effectiveness in controlling soil-borne bacterial wilt of tomatoes. Current technologies lack research on effective strain combinations for the control of bacterial wilt.
A combination of copper-loving bacterium CUP3 and ornithine-releasing bacterium RAO1 was used to prepare a bacterial composition and fermentation broth. By utilizing metabolic complementarity and enhanced nutrient competition, the colonization ability and disease suppression effect in the rhizosphere were improved, and the results were applied to control soil-borne bacterial wilt in tomatoes.
It significantly reduced the incidence of bacterial wilt in tomatoes, improved the colonization success rate and antibacterial effect of beneficial bacteria, and provided an efficient and stable green control solution.
