Leaf spot is caused by fungi that thrive in hot and humid conditions. The disease is characterized by small brown or black spots on the leaves. These spots can merge and form large patches, causing the leaves to turn yellow and eventually drop off.

Root Rot

Root rot is caused by fungi that attack the roots of the corn cane plant. The disease is characterized by wilting leaves and a darkening of the stem at the soil line. The roots of infected plants will appear brown and mushy.

Powdery Mildew

Powdery mildew is a fungal disease that affects the leaves of corn cane plants. The disease is characterized by a white powdery coating on the leaves. Infected leaves may also become distorted or yellow.

Mealybugs

Mealybugs are small insects that feed on the sap of corn cane plants. Infested plants will have white cotton-like masses on the stems, leaves, and flowers. Mealybugs weaken the plant and make it more susceptible to other diseases.
