Management of black rot in cabbage by rhizospheric Pseudomonas species and analysis of 2,4-diacetylphloroglucinol by qRT-PCR

► One of the very few reports on biological control of black rot in cabbage. ► Rhizospheric microbes efficiently managed black rot both in vitro and in vivo. ► Root dip treatment was better than soil and foliar, in black rot management. ► Detection of 2,4-DAPG as one of the several metabolite responsible for biocontrol. ► It's production was monitored by qRT-PCR of phlD gene in various conditions.
