✅ Spray Neem-based pesticides (Azadirachtin 300 ppm).
✅ Use Imidacloprid 17.8% SL or Thiamethoxam 25% WG if infestation is severe.
🦗 1.3 Root Grubs (Basilepta fulvicorne)
Symptoms:
- Wilting plants due to root damage.
- Grubs feed on roots, leading to poor growth.
- Yellowing leaves and stunted plants.
Control Measures:
✅ Apply Metarhizium anisopliae (fungal bio-pesticide).

Symptoms:
- Dark brown spots on leaves.
- Leaves dry up and fall prematurely.
- Reduces photosynthesis and yield.
Control Measures:
✅ Spray Bordeaux mixture (1%) or Mancozeb 75% WP.
✅ Maintain good air circulation around plants.

🍂 2.4 Damping-Off Disease (Fungal Rot in Seedlings)
Symptoms:
- Seedlings wilt and die suddenly.
- Brown, water-soaked lesions on young plants.
- Common in nurseries & waterlogged soils.
Control Measures:
✅ Drench soil with Copper Oxychloride (0.2%).
✅ Apply Pseudomonas fluorescens (biological control).
✅ Ensure proper drainage & avoid overwatering.
