Integrated biocontrol of tobacco bacterial wilt by antagonistic bacteria and marigold

Abstract Tobacco bacterial wilt (TBW) is seriously damages the growth of tobacco. There is an urgent need to find a safer and more effective measure to control TBW. In this study, B. amyloliquefaciens ZM9 and marigold powder were applied to the tobacco roots alone or in combination, and the potentia...
