Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Red Rot is one of the oldest and most devastating fungal diseases affecting agricultural crops in tropical and subtropical regions.
Recognizing major plant diseases and their host crops is a fundamental aspect of agricultural sciences.

Step 2: Detailed Explanation:
Red Rot disease is caused by the fungal pathogen Colletotrichum falcatum Went (perfect state Glomerella tucumanensis).
This disease primarily attacks Sugarcane (Saccharum officinarum), causing severe yield losses and reduction in juice quality.
Symptoms of the disease include:
- Yellowing and drooping of the upper leaves of the sugarcane plant.
- Splitting open of affected stalks reveals characteristic red internal tissues with distinctive white transverse bands.
- A typical sour, alcoholic odor emanates from the infected split canes due to fermentation of sugars by the pathogen.
Hence, the disease is exclusively and widely associated with sugarcane.

Step 3: Final Answer:
"Red Rot" disease is related to Sugarcane.
