Ganoderma Butt Rot

Ganoderma Butt Rot, is caused by the fungus Ganoderma zonatum, is very dangerous. It’s a white rot fungus that destroys lignin in the lower trunks which often leads to tree trunks being snapped in half.

Containment is particularly difficult because its fruiting bodies release billions of spores, that spread by wind, and infect palm trunks from the soil upward.

It’s considered a pathogen but acts very opportunistic because it tends to infects palm trees that are already structurally weakened.

What makes detecting this disease tricky is that the tree can look very healthy in the canopy and by the time symptoms are seen, the tree is already in bad shape.

Effectively getting rid of this disease can be difficult. The fungus can stay alive in wood pieces and soil, which can be a risk to any new planted trees in the area. Even removing the old soil with new fill is not guaranteed in preventing it.
