Black mould (Cercospora abelmoschi)
Black mould can be serious in humid warm areas. It causes leaf spots of various shapes. It grows as a sooty to dark oily (olivaceous) mould on the underside of leaves, but when infection is severe and conditions are very humid it also appears on upper surface of infected leaves. Seriously infected foliage rolls, wilts and falls to the ground.
