Third or mature spot stage: the centre of the spot dries out, becoming light grey or buff-coloured, and further depressed. The spot is surrounded by a narrow, well-defined, dark brown or black border. between the latter and the normal green colour of the leaf, there is often a bright yellow transitional zone. After the leaf has collapsed and withered, spots remain clearly visible because of the light-coloured centre and dark border.

Initial speck stage: symptoms are first visible to the naked eye as faint, minute (less than 0.25 mm diam), reddish brown specks on the lower surface of the leaf. Specks are often most abundant near the margin of the left side of the leaf, particularly towards the tip. Where leaf spot is severe, specks have been observed on the second leaf of plants that have not yet produced a bunch. Elsewhere they usually appear on the third, fourth, or older leaves.

Stage 6 is when the centre of the spot dries out, turns clear gray and is surrounded by a well-defined black ring, which is, in turn, surrounded by a bright yellow halo. These spots remain visible after the leaf has dried out because the ring persists.

Stage 2 appears as a stripe, generally brown in colour and visible on the underside of the leaf, later the symptom also appears on the upper part of the limb as a stripe, the yellow colour of which resembles the stripe at stage 1 of Yellow Sigatoka. The colour of this stripe will change progressively from brown and later to black on the upper side of the limb, but will retain the brown colour on the underside.

First-spot stage: the streak broadens and becomes more or less fusiform and elliptical in outline and similar to the first-spot stage of Sigatoka (Leach 1946). The transition from streak to spot is further characterised by the development of a light brown, water-soaked border around the spot. This water-soaked effect is especially clear in the early morning, when dew is still present on the leaf, or after rain.

Stage 1 appears as a small depigmentation spot whose whitish or yellow colour resembles stage 1 of Yellow Sigatoka disease. These symptoms are not visible in transmitted light and can be observed only on the underside of the leaf.
1
First streak stage: the initial speck elongates, becoming slightly wider, to form a characteristic narrow, reddish brown streak up to 20 mm long and 2.0 mm wide, with the long axis parallel to the leaf venation. At this stage, streaks are more clearly visible on the lower surface of the leaf than on the upper one. The distribution of streaks is variable. Sometimes they are most numerous near the edge of the left side of the leaf. At other times they are equally numerous on both sides of the leaf, and more or less evenly distributed. Frequently they are densely aggregated in a band several cm wide on one side or both sides of the mid-rib, becoming less numerous towards the edge of the leaf. Streaks may be so numerous that every cm2 of leaf surface bears one or more. There is considerable variation in the length of individual streaks on a given leaf, and they frequently overlap to form larger, compound streaks.
