Question

Given below are two statements:
Statement (I): Management means to maintain weed population below a threshold level, however, control remains implicit in management.
Statement (II): Integrated weed management (IWM) necessarily embraces that a combination of the methods of weed control rather than a single method be exercised for management of weeds below a threshold population.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Remember that control is one tool used inside the broader goal of weed management.

Answer 1

The Correct Option is A

This question checks the difference between weed control and weed management, and how integrated weed management, or IWM, fits into that picture.

1. Statement I: Management is described as keeping the weed population under a threshold, with control being just one implicit tool inside that broader goal. This is the accepted distinction in weed science, so it is true.
2. Statement II: IWM is described as always needing a mix of control methods rather than a single method, to keep weeds below the threshold. IWM is defined exactly this way, combining cultural, mechanical, biological, and chemical tools together, so this is also true.

Both statements line up with how management, control, and IWM are defined in weed science, so option 1 is the right choice.

Let's summarize:

• Management is the broad goal of keeping weeds below a damaging threshold, control is one tool used within it.
• IWM by definition blends more than one control method to reach that goal.

So the final answer is that both statements are correct.
