1. Quick Wilt/Foot Rot:
- Symptoms: Black spots on leaves, wilting stems, stunted growth, eventual collapse.
- Cause: Fungus (Phytophthora capsici) thrives in soggy soil.
- Organic Remedy: Improve drainage, avoid overwatering, use raised beds, apply Bordeaux mixture or neem oil spray.
2. Anthracnose (Pollu):
- Symptoms: Brown sunken spots on leaves and berries, cracking and shriveled berries, defoliation.
- Cause: Fungus (Colletotrichum gloeosporoides) spreads in humid conditions.
- Organic Remedy: Improve air circulation, prune affected parts, spray with neem oil or garlic solution, mulch with plant residues.
3. Bacterial Leaf Spot:
- Symptoms: Yellow or brown spots on leaves, leaf drop, stunted growth.
- Cause: Bacteria (Xanthomonas campestris pv. piperata) thrives in warm, humid environments.
- Organic Remedy: Remove infected leaves, rotate crops, spray with Bordeaux mixture or copper oxychloride, ensure good sanitation.
4. Mosaic Virus:
- Symptoms: Mottled leaves, stunted growth, distorted leaves, yellowing.
- Cause: Virus transmitted by aphids and other insects.
- Organic Remedy: Control aphids with neem oil or soapy water, remove infected plants, plant resistant varieties.
5. Damping-Off Disease:
- Symptoms: Seedling stems collapse at soil line, wilting, brown discoloration.
- Cause: Fungus (Pythium spp.) thrives in poorly drained soil and cool temperatures.
- Organic Remedy: Use sterile potting mix, avoid overwatering, thin seedlings for better air circulation, treat seeds with garlic solution.
6. Root Knot Nematodes:
- Symptoms: Stunted growth, galls or knots on roots, yellowing leaves, wilting.
- Cause: Microscopic worms (Meloidogyne spp.) damage roots, reducing nutrient uptake.
- Organic Remedy: Plant marigolds as trap crops, rotate crops, solarize soil, use neem cake or Trichoderma fungus for biocontrol.
7. Charcoal Rot:
- Symptoms: Stems blacken and crack, leaves wilt and drop, rapid plant death.
- Cause: Fungus (Macrophomina phaseolina) survives in soil debris.
- Organic Remedy: Remove and burn infected plants, practice crop rotation, improve soil drainage, avoid excessive nitrogen fertilization.
8. Leaf Blight:
- Symptoms: Large, irregular brown spots on leaves, defoliation, stunted growth.
- Cause: Fungus (Botrytis cinerea) favors cool, wet conditions.
- Organic Remedy: Improve air circulation, prune affected parts, spray with neem oil or potassium bicarbonate solution.
9. Powdery Mildew:
- Symptoms: White powdery growth on leaves and stems, stunted growth, yellowing.
- Cause: Fungus (Leveillula taurica) thrives in high humidity and poor air circulation.
- Organic Remedy: Improve air circulation, spray with baking soda solution or milk-water mixture, avoid overhead watering.
10. Canker Disease:
- Symptoms: Raised, sunken lesions on stems and branches, cracking, dieback.
- Cause: Fungus (Phomopsis piperata) enters through wounds or insect damage.
- Organic Remedy: Prune off affected branches, sterilize pruning tools, apply Bordeaux mixture or neem oil as a preventive measure.
