Question

Match List-I with List-II

List-I (Name of crop diseases) & List-II (Name of the crops)
(A) Tikka disease & (IV) Groundnut
(B) Stripe rust & (III) Wheat
(C) Neck blast & (I) Rice
(D) Fusarium wilt & (II) Pigeonpea

• (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)

Hint:

Remember the classic pathological terms:
- Tikka is the hallmark disease of Groundnut.
- Yellow Stripe Rust is a major constraint in Wheat cultivation.
- Blast is the most destructive disease of Rice.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Crop diseases caused by fungi can devastate yields of staple and commercial crops.
Identifying the host crops associated with classic plant diseases is fundamental to plant protection and agronomy.

Step 2: Detailed Explanation:
Let us match each plant disease in List-I with its primary host crop in List-II:
- (A) Tikka disease $\rightarrow$ (IV) Groundnut:
Tikka disease (early and late leaf spot) is the most common and destructive fungal disease of groundnut (*Arachis hypogaea*), caused by the fungi *Cercospora arachidicola* and *Cercosporidium personatum*.
- (B) Stripe rust $\rightarrow$ (III) Wheat:
Stripe rust (yellow rust) is a devastating biotrophic fungal disease of wheat (*Triticum aestivum*), caused by the pathogen *Puccinia striiformis* f. sp. *tritici*.
- (C) Neck blast $\rightarrow$ (I) Rice:
Blast is the most critical fungal disease of rice (*Oryza sativa*), caused by *Magnaporthe oryzae*. When it infects the neck of the panicle, it is called neck blast, causing the panicle to fall over and fail to fill grain.
- (D) Fusarium wilt $\rightarrow$ (II) Pigeonpea:
Wilt is a soil-borne vascular disease of pigeonpea (*Cajanus cajan*), caused by the fungal pathogen *Fusarium udum*, causing xylem clogging and plant wilting.
This results in the sequence: (A)-(IV), (B)-(III), (C)-(I), (D)-(II).

Step 3: Final Answer:
The correct matching sequence is (A) - (IV), (B) - (III), (C) - (I), (D) - (II).
