The latest trend in plant disease control is

Options

A. Chemical control
B. Biological control
C. Good manure anf fertilizer
D. Breeding for disease resistance

Answer

To solve the question regarding the latest trend in plant disease control, let's analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding the Options**: The options given are:
- A) Chemical control
- B) Biological control
- C) Good manure
- D) Anti-fertilizer
- E) Breeding for disease resistance

2. **Evaluating Chemical Control**:
- Chemical control involves the use of synthetic pesticides and herbicides to manage plant diseases.
- While effective, it can be harmful to the environment and non-target organisms.
- **Conclusion**: This option is not considered the latest trend due to its negative impacts.

3. **Evaluating Biological Control**:
- Biological control refers to the use of living organisms, such as predators, parasites, or pathogens, to control pest populations and plant diseases.
- This method is more sustainable and environmentally friendly, making it easier to adopt in modern agriculture.
- **Conclusion**: This option is a strong candidate for the latest trend in plant disease control.

4. **Evaluating Good Manure**:
- Good manure is primarily used to enhance soil fertility and promote plant growth rather than directly controlling diseases.
- While it supports healthy plants, it is not a direct method for disease control.
- **Conclusion**: This option is not relevant to the question.

5. **Evaluating Anti-fertilizer**:
- Anti-fertilizers are substances that inhibit plant growth and are not typically used for disease control.
- They do not contribute positively to managing plant diseases.
- **Conclusion**: This option is irrelevant.

6. **Evaluating Breeding for Disease Resistance**:
- Breeding for disease resistance involves developing plant varieties that are genetically resistant to specific diseases.
- While this is an important strategy in agriculture, it is more of a long-term approach rather than the latest trend.
- **Conclusion**: This option is not the most current trend.

7. **Final Conclusion**:
- After evaluating all the options, the most appropriate answer is **B) Biological control**, as it represents the latest trend in sustainable plant disease management.

### Final Answer:
The latest trend in plant disease control is **Biological control**.
