2, 4-D is an effective

Options

A. Rodenticide
B. Wormicide
C. Fungicide
D. Weedicide

Answer

**Step-by-Step Solution:**

1. **Identify the Compound**: The question asks about 2,4-D, which stands for 2,4-Dichlorophenoxyacetic acid. This is a key detail that helps in understanding its function.

2. **Understand the Function**: 2,4-D is primarily used in agriculture and is known for its effectiveness against certain types of plants. It is particularly effective on dicotyledonous plants (dicots).

3. **Differentiate Between Plant Types**: It is important to note that 2,4-D does not affect monocotyledonous plants (monocots) such as grasses. This distinction is crucial for identifying its role.

4. **Determine the Correct Classification**: Given that 2,4-D is used to kill unwanted plants (weeds) that are typically dicots, it is classified as a herbicide or weedicide.

5. **Eliminate Incorrect Options**:
- Rodenticide is used to kill rodents, which is not relevant here.
- Vermicide is used to kill worms, which is also not applicable.
- Fungicide is used to kill fungi, again not relevant to 2,4-D.

6. **Conclude with the Correct Answer**: The only correct classification for 2,4-D is that it is a weedicide or herbicide.

**Final Answer**: 2,4-D is an effective weedicide (herbicide).
