The bacterium is transmitted through seed and water splash. Symptoms consist of spots on leaves and pods. Leaf spots are initially soaked with water and are more obvious on the underside of leaves. They are restricted to the veins and are angular in shape. Spots on petioles are elongated, sometimes slightly sunken and blackish. Spots on pods are initially water-soaked and round. Later, they join together and turn oily black. All spots appear waxy and shiny.
