Photo 1. Coconuts growing in the high rainfall interior of Malaita, Solomon Islands, showing early infection of thread blight, Corticium penicillatum, on older leaves, mostly at the ends.
Photo 2. Severe infection of thread blight, Corticium penicillatum, over most leaves of a group of coconuts in a high rainfall area of Malaita, Solomon Islands. Cloud cover is high, as is rainfall, and the coconuts are growing at the bottom of a valley, with a river to the right.
Photo 3. Threads of the fungus Corticium penicillatum along the midrib of a coconut leaf causing rots at the base of the leaflets.
Photo 4. Extensive damage along the entire leaf of a coconut frond by thread blight, Corticium penicillatum, as seen from the underside.
