Halo blight of bean is a bacterial disease caused by ''Pseudomonas syringae pv. phaseolicola''. Halo blight’s pathogen is a gram-negative, aerobic, polar-flagellated and non-spore forming bacteria.This bacterial disease was first discovered in the early 1920s, and rapidly became the major disease of beans throughout the world. The disease favors the places where temperatures are moderate and plentiful inoculum is available.〔Harveson, Robert M.
