Production of pest resistant plants could

Options

A. Increase the amount of pesticide used
B. Increase the amount of weedicide used
C. Decrease the amount of pesticide used
D. Both (2) & (3)

Answer

To answer the question regarding the production of pest-resistant plants, we need to analyze the options provided and understand the implications of developing such plants.

### Step-by-Step Solution:

1. **Understanding Pest-Resistant Plants**:
- Pest-resistant plants are genetically modified or bred to have enhanced abilities to resist pests and diseases. This can be achieved through various biotechnological methods, such as the introduction of Bt toxins or RNA interference.

2. **Analyzing the Options**:
- **Option A: Increase the amount of pesticide use**:
- If plants are resistant to pests, there would be less need to use pesticides. Therefore, this option is incorrect.

- **Option B: Increase the amount of weedicide use**:
- Weedicide is used to control weeds, not pests. The development of pest-resistant plants does not directly influence the need for weedicide. Thus, this option is also incorrect.

- **Option C: Decrease the amount of pesticide use**:
- Since pest-resistant plants can naturally fend off pests, the reliance on chemical pesticides would decrease. This option is correct.

- **Option D: Both 2 and 3**:
- Since option B is incorrect (there is no need to increase weedicide use), this option is also incorrect.

3. **Conclusion**:
- The correct answer is **Option C: Decrease the amount of pesticide use**. This reflects the benefit of producing pest-resistant plants, as they reduce the need for chemical pest control measures.

### Final Answer:
The production of pest-resistant plants could **decrease the amount of pesticide use** (Option C).
