What is a Red Rot Disease ?

Red rot is a serious fungal disease that primarily affects sugarcane. It's caused by the fungus Colletotrichum falcatum (also known as Glomerella tucumanensis). Red rot can cause significant yield losses as the infected cane becomes unusable for sugar production.

Short Description of Red Rot Disease

Here is the detail information related to the Red Rot Disease:

Type of Infestation	Fungal Disease
Common Name	Red Rot
Scientific Name	Glomerella tucumanensis
Affected Parts Of the plant	Stem and Leaf

Favorable factors for Red Rot Disease

Optimal temperatures are between 28-32°C (82-90°F). Higher temperatures can slow disease progression, but the fungus remains viable. High relative humidity is crucial for the disease to spread. Rain, irrigation, and waterlogged conditions create the moisture needed for infection.
