Ganoderma Disease: Identification, Effects, and Control

Ganoderma Disease

Overview

Ganoderma disease (Ganoderma zonatum), also called ganoderma butt rot, is a fungal infection affecting trees worldwide.

Tree fails to thrive. Brackets (fungal fruiting bodies) grow at tree base.

Young trees tolerate infection. Effects worsen with age—branches and leaves die.

Airborne spores enter through bark injuries, travel to core.

Temperature and humidity influence kill rate.

No chemical controls. Only effective measure: remove infected trees and soil from the location.
