Practical Investigation Methods
Visual Symptom Recognition
| Symptom Type | What to Look For | Likely Cause |
|---|---|---|
| Spots/Lesions | Black, brown, or colored circular patches | Fungal infections |
| Mosaic Patterns | Light and dark patches, mottling | Viral infections |
| Wilting | Drooping despite adequate water | Bacterial or fungal root disease |
| Yellowing (Chlorosis) | Loss of green color in leaves | Nutrient deficiency or pathogen |
| Stunted Growth | Smaller than normal plants | Viral infections or soil pathogens |
Field Study Protocol
- Site Selection: Choose representative area with affected plants
- Visual Survey: Examine plants systematically for symptoms
- Documentation: Photograph or sketch symptoms with scale
- Sample Collection: Collect diseased tissue for closer examination
- Data Recording: Note environmental conditions, plant species, severity
- Identification: Use field guides or keys to identify disease
- Follow-up: Monitor disease progression over time
