Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of herbicides for controlling specific weeds.
Step 2: Detailed Explanation:
Ageratum houstonianum (blueweed) can be effectively controlled post-emergence with Thiobencarb @ 1.0 kg ha-1.
Atrazine (A): Primarily a pre-emergence herbicide.
Pendimethalin (B): Pre-emergence herbicide.
Alachlor (C): Pre-emergence herbicide.
Thus, Thiobencarb is the correct answer.
Step 3: Final Answer:
Thus, effective post-emergence control of Ageratum houstonianum is achieved with Thiobencarb @ 1.0 kg ha-1, which corresponds to option (D).
