Discussion
Match Group I (plant disease), Group II (causal organism) and Group III (affected plant) in CORRECT combination.
| Group-I | Group-II | Group-III |
|---|---|---|
| P. Karnal Bunt | I. Phytophthora infestans | a. Rice |
| Q. Ergot | II. Blumeria graminis | b. Potato |
| R. Late blight | III. Neovossia indica | c. Rye |
| S. Powdery mildew | IV. Puccinia recondita | d. Wheat |
| V. Claviceps purpurea | e. Barley | |
| VI. Alternaria solani | f. Brinjal |
Answer: C
The correct combination is P-III-d, Q-V-c, R-I-b, S-II-e.
- Karnal bunt of wheat (d) is caused by Neovossia indica (III), also called Tilletia indica, first reported from Karnal, Haryana.
- Ergot is caused by Claviceps purpurea (V), and rye (c) is its classic host.
- Late blight of potato (b) is caused by the oomycete Phytophthora infestans (I), the agent of the Irish famine.
- Powdery mildew of barley (e) is caused by Blumeria graminis (II).
The leftovers are distractors: Puccinia recondita causes brown (leaf) rust of cereals, and Alternaria solani causes early blight of potato and tomato. Option B assigns late blight to Blumeria and powdery mildew to a rust, and options A and D misplace Karnal bunt.
