Minor Pest Title
Armillaria root rot (Armillaria heimii)
Minor Pest Description
Symptoms include wilting of leaves, death of verticals and subsequent death of affected trees. The root system of affected trees shows a white growth (mycelial) of the fungus beneath the bark. In advanced stage of the disease the wood of the affected tree is decomposed into a white, wet mass with characteristic black zone lines running through the wood tissue. Vertical cracks may occur at the base of the stem at this stage. Initial infection in coffee plantings usually can be traced to shade trees or woody debris (stumps or old roots of shade trees) left in the ground when land is cleared before coffee planting.
Minor Pest What to do.
- Where coffee has to be planted in newly cleared forest land, it is recommended that ring-barking of the forest trees be done 2 to 3 years earlier.
- Remove forest trees stumps, remove as much as possible of forest trees roots, and drench the root area with a copper fungicide.
- It is not possible to save a coffee tree once infected. The infected tree should be uprooted and replanting should be delayed for 2 years.
