Options

A. Only Bioinsecticide
B. Only bioherbicide
C. Bioinsecticde and bioherbicide
D. Bioherbicide ,bioinsecticide ,and biofertilizers

Answer

### Step-by-Step Solution:

1. **Understanding Biopesticides**:
- Biopesticides are defined as pesticides derived from natural materials such as plants, animals, or microorganisms. They serve as alternatives to synthetic pesticides and are generally considered more environmentally friendly.

2. **Types of Biopesticides**:
- There are primarily two types of biopesticides:
- **Bioinsecticides**: These are used to control insect pests. They can be derived from natural sources such as bacteria, fungi, or plant extracts that specifically target and kill insects.
- **Bioherbicides**: These are used to control weeds. Similar to bioinsecticides, they can be derived from natural materials that inhibit or kill unwanted plant species.

3. **Examples of Biopesticides**:
- Common examples include substances like canola oil and baking soda, which can be used to manage pest populations without the adverse effects associated with chemical pesticides.

4. **Evaluating the Options**:
- The question provides four options regarding what biopesticides include:
1. Only bioinsecticide
2. Only bioherbicide
3. Bioinsecticide and bioherbicide
4. Bioherbicide, bioinsecticide, and biofertilizers
- Since biopesticides specifically refer to bioinsecticides and bioherbicides, we can eliminate options 1 and 2.

5. **Correct Answer**:
- The most comprehensive option that accurately describes biopesticides is option 3: **bioinsecticide and bioherbicide**. Option 4 includes biofertilizers, which are not classified as biopesticides.

### Final Answer:
- **Biopesticides include**: Bioinsecticide and bioherbicide (Option 3).
