This disease is caused by the fungus Ganoderma Zonatum that entering a palm through a wound in the butt area, 40/50 cm under the soil. From there it rapidly makes its way into the tree eventually rotting the wood. Once the fungus has made its way into the centre of the plant, it forms a spongy, white mushroom like growth that is referred to as a “conk”. This will form a horizontal disk on the bark of the palm.
Bud rot causes premature death of the spear leaf, but will not cause premature death of the lowest leaves in the canopy. This type of disease attacks the heart fronds of palms. It is a type of fungus that infests the fronds thereby causing them to shrivel up and die. Watch out especially during summer, as this is the season when Bud Rot is most likely to occur.
Fusarium Wilt is a deadly disease and causes permanent damage to the plant. This means that once it has been infected, there is no known cure. The infected plant must be removed to prevent fungi spores spreading.
