Question

Match List I with List II - Match the mode of action in List I with the herbicides in List II:

List I & List II
Mode of action & Herbicide
A. Cell division disruption & I. Fluazifop-p-butyl
B. ALS inhibition & II. Glyphosate
C. ACCase inhibition & III. Dinitroaniline
D. EPSP synthase & IV. Sulfonyl ureas

Choose the correct answer from the options given below:

• A. A-II, B-IV, C-III, D-I
• B. A-II, B-IV, C-I, D-III
• C. A-III, B-I, C-IV, D-II
• D. A-III, B-IV, C-I, D-II

Hint:

Dinitroaniline: disrupts cell division.
Sulfonyl ureas: ALS inhibitors.
Fluazifop: ACCase inhibitor.
Glyphosate: EPSP synthase inhibitor.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Herbicides have different modes of action.
We need to match each mode with the correct herbicide.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the modes of action.

Step 3: Detailed Explanation:
Cell division disruption: Dinitroaniline (A-III).
ALS inhibition: Sulfonyl ureas (B-IV).
ACCase inhibition: Fluazifop-p-butyl (C-I).
EPSP synthase: Glyphosate (D-II).
Thus, A-III, B-IV, C-I, D-II is the correct matching.

Step 4: Final Answer:
The correct matching is A-III, B-IV, C-I, D-II.
Hence, the correct option is (D).
