Answer

To determine how many statements are incorrect, let's analyze each statement one by one:

### Step 1: Analyze Each Statement

1. **Statement i**: "Microbes comprise of diverse organisms like protozoa, bacteria, fungi and microscopic plants, viruses, viroids and also prions that are proteinaceous infectious agents."
- **Analysis**: This statement is true. Microbes indeed include a wide variety of organisms, including protozoa, bacteria, fungi, microscopic plants (like algae), viruses, viroids, and prions.

2. **Statement ii**: "Microbes like bacteria, viruses and many fungi can be grown on nutritive media to form colonies."
- **Analysis**: This statement is incorrect. While bacteria and fungi can be grown on nutritive media, viruses cannot be grown on such media as they require a living host to replicate.

3. **Statement iii**: "In our stomach, the LAB plays a very beneficial role in checking disease-causing microbes."
- **Analysis**: This statement is true. Lactic Acid Bacteria (LAB) are beneficial and help in maintaining gut health by inhibiting harmful microbes.

4. **Statement iv**: "'Toddy', a traditional drink of some parts of southern India is made by fermenting sap from sugarcane."
- **Analysis**: This statement is incorrect. Toddy is actually made from the sap of palm trees, not sugarcane.

### Step 2: Count the Incorrect Statements
- From the analysis:
- Statement ii is incorrect.
- Statement iv is incorrect.

Thus, there are **2 incorrect statements**.

### Final Answer
The number of incorrect statements is **2**.
