Question

The cause of damping off disease is

• A. Bacteria
• B. Fungus
• C. Virus
• D. Fertilizer

Hint:

For seedling rots and “falling over” symptoms, first suspect soil-borne fungi (Pythium/Rhizoctonia).

Answer 1

The Correct Option is B

Step 1: Understand damping off.
Damping off is a seedling disease characterized by pre- or post-emergence rot at the collar/root zone.
Step 2: Causal organisms.
It is primarily caused by fungal pathogens like \textit{Pythium}, \textit{Rhizoctonia}, and \textit{Fusarium}. Bacteria/viruses or fertilizers are not the causal agents.
Step 3: Conclusion.
Hence, the correct cause is Fungus.
