Oval or circular brown spots are present on both surfaces of the leaves. Small black bodies may be seen scattered over the surface of the spots. Infected stems are girdled, causing them to collapse and die. These spots may have a target- board effect.
Infected plants appear ragged due to leaf fall and blight of the twigs.
Pale green, water-soaked spots appear on the leaves. As the spots enlarge, they become brown or black with red margins. The leaf petioles become black and shrivel. The black decay may extend from the tips of young twigs into the old wood. Cankers may form on the stems, girdling them.
