Your plant’s leaves turning yellow, brown, or spotted? 🌿 You may be facing one of the world’s most common plant diseases. In this guide, we’ll explore the Top 10 Plant Diseases that every gardener should know — and how to treat them using simple, natural, and AI-assisted solutions.



1. Powdery Mildew


Symptoms: White powdery coating on leaves and stems.


Cause: Fungal spores thrive in dry air and poor circulation.


Natural Fix: Mix 1 tbsp baking soda + 1 tsp neem oil in 1 liter of water. Spray weekly. Improve airflow and reduce overhead watering.



2. Root Rot


Symptoms: Yellow leaves, soft roots, and foul smell from soil.


Cause: Overwatering or poor drainage allows fungi to attack roots.


Fix: Remove plant, cut damaged roots, and repot in fresh, well-draining soil. Water only when top 1 inch of soil is dry.



3. Leaf Spot Disease


Symptoms: Brown, black, or yellow circular spots on leaves.


Cause: Fungal or bacterial infection due to high humidity.


Fix: Remove affected leaves. Spray neem oil or copper fungicide. Avoid misting during evening hours.



4. Rust Fungus


Symptoms: Orange or brown pustules under leaves.


Fix: Isolate infected plants. Use organic fungicide spray weekly. Keep foliage dry and ensure proper ventilation.



5. Blight


Symptoms: Rapid leaf death starting from tips or edges.


Cause: Bacterial or fungal infection spread by rain splash.


Fix: Remove dead foliage immediately. Avoid overhead watering. Apply bio-fungicide if necessary.



6. Wilt Disease


Symptoms: Sudden drooping of stems even when soil is moist.


Cause: Vascular fungus blocks water flow inside the plant.


Fix: Improve soil drainage and rotate crops. Use AI diagnosis tools like Plant Solutions to confirm the fungus type before treatment.



7. Anthracnose


Symptoms: Dark sunken spots on leaves and fruits.


Fix: Prune infected parts and destroy them. Use neem or sulfur spray. Maintain dry leaf surfaces during watering.



8. Mosaic Virus


Symptoms: Mottled or patchy light-green patterns on leaves.


Cause: Virus spread through insects or tools.


Fix: Remove infected leaves and disinfect pruning tools. Boost immunity using organic compost and balanced fertilizer.



9. Sooty Mold


Symptoms: Black, sticky coating on leaves.


Cause: Sap-sucking insects like aphids and whiteflies produce honeydew, which grows mold.


Fix: Clean leaves with mild soapy water. Control pests using neem oil or organic insect spray.



10. Damping-Off (Seedling Disease)


Symptoms: Young seedlings collapse at the base and die suddenly.


Cause: Fungal growth in wet soil or poor ventilation.


Fix: Use sterile seed-starting mix. Avoid overwatering. Allow airflow and sunlight for healthy germination.
