In the following table identify the correct matching of the crop its decrease and the corresponding pathogen

Options

A. `{:("Crop ", D"isease","Pathogen"),("citurs", "cancker", "Pseudomonas rubrilineans"):}`
B. `{:("Crop ", D"isease","Pathogen"),("potato","late blight","Fusarium vdum"):}`
C. `{:("Crop ", D"isease","Pathogen"),("brinjal", "root knot", "Meloidogyne incognita"):}`
D. `{:("Crop ", D"isease","Pathogen"),("pigeon pea", "seed gall", "Phytophatora infestans"):}`

Explanation

To solve the question regarding the correct matching of crops, their diseases, and corresponding pathogens, we will analyze each option provided in the table step by step.

### Step-by-Step Solution:

1. **Analyze the First Option:**
- **Crop:** Citrus
- **Disease:** Canker
- **Pathogen:** Pseudomonas rubrillens
- **Evaluation:** Pseudomonas rubrillens is known to cause seedling blight and bacterial blotch, primarily affecting cucurbit plants, not citrus. Therefore, this match is **incorrect**.

2. **Analyze the Second Option:**
- **Crop:** Potato
- **Disease:** Late blight
- **Pathogen:** Fusarium odum
- **Evaluation:** Fusarium odum is a fungus that causes seedling blight and root rot, primarily affecting barley and wheat, not potatoes. Thus, this match is also **incorrect**.

3. **Analyze the Third Option:**
- **Crop:** Brinjal
- **Disease:** Root knot
- **Pathogen:** Melodigyne incognita
- **Evaluation:** Melodigyne incognita is indeed the pathogen that causes root knot disease in brinjal. This match is **correct**.

4. **Analyze the Fourth Option:**
- **Crop:** Pigeon pea
- **Disease:** Seed gall
- **Pathogen:** Phytophthora infestans
- **Evaluation:** Phytophthora infestans is known for causing late blight in potatoes and tomatoes, not seed gall in pigeon pea. Therefore, this match is **incorrect**.

### Conclusion:
The only correct match from the options provided is:
- **Brinjal - Root knot - Melodigyne incognita.**

### Final Answer:
The correct matching is **Option 3: Brinjal, Root knot, Melodigyne incognita.**
