Causes of Sunburn in Banana Plants

1. High Temperatures: Above 35°C increases sunburn risk.
2. Direct Sunlight: Plants without shade are more vulnerable.
3. Water Deficiency: Weakens plant cells, increasing heat stress.
4. Nutrient Deficiency: Lack of potassium, calcium, and silicon reduces heat resistance.

Symptoms of Sunburn

• Yellow/Brown patches on leaves.
• Scorched leaf tips that dry out.
• Black/Brown marks on fruit.
• Wilted or curled leaves during hot hours.

 Solutions :

✅ Helmet (Protective Shield)

• Forms a protective film to reduce heat damage.
• Minimizes water loss and improves heat tolerance.
• Dosage: 3-5 ml per liter of water (Spray early morning or late evening).

✅ Silicoboost (Silicon Growth Enhancer)

• Strengthens plant cells and boosts heat resistance.
• Improves nutrient absorption for better plant health.
• Dosage: 2-3 ml per liter of water (Repeat every 15-20 days).

Additional Tips

✅ Use shade nets (50-60%) for young plants.
✅ Apply organic mulch to retain soil moisture.
✅ Ensure regular irrigation during summer.
