1. Red Rot:
Red Rot is a devastating fungal disease affecting sugarcane, caused by the pathogen Colletotrichum falcatum. Characterized by red discoloration in the internal tissues of the sugarcane stalks, this disease hinders sucrose accumulation and reduces overall yield. Early detection and proper management practices are crucial to mitigate the impact of Red Rot.

2. Grassy Shoot:
Grassy Shoot is a viral disease in sugarcane, primarily transmitted by aphids. Infected plants exhibit excessive tillering, stunted growth, and a proliferation of narrow, grass-like shoots. This disease can significantly reduce sugarcane yield and quality. Implementing vector control measures and cultivating resistant varieties are essential strategies for Grassy Shoot management.

3. Ratoon Stunting:
Ratoon Stunting Disease (RSD) is caused by the Leifsonia xyli subsp. xyli bacterium. It affects the regrowth (ratoons) of sugarcane plants, leading to stunted growth, poor tillering, and reduced sugar content. RSD can persist in the soil, impacting successive crops. Employing disease-free planting material and practicing crop rotation are crucial for managing Ratoon Stunting.

4.Pokkah Boeng:
Pokkah Boeng, also known as "Orange Spot," is a fungal disease caused by the pathogen Corticium sasakii. It manifests as small, orange-brown spots on sugarcane leaves, eventually leading to leaf necrosis and reduced photosynthesis. This disease can negatively impact sugar yield and plant vitality. Timely fungicide applications and maintaining proper field hygiene are essential for controlling Pokkah Boeng in sugarcane crops.
