Coffee berry disease
Recognize the problem
This is a disease caused by a fungus (Colletotrichum). It is also known
as brown blight of coffee. It forms dark depressed wounds on green berries. The
disease is especially seen during the wet season.
The whole berry rots. The berries dry out and
prematurely drop off the coffee tree. The disease develops faster during the
wet season. It does not kill the trees, but it lives within the stem. Signs of
the disease are very rare on leaves. It is spread by rain splash, by coffee
pickers, birds and movement of infected seedlings. All stages of growth of the
plant can be infected but symptoms are only seen on the green and ripe berries.
The disease depends upon the
availability of water for its development.
