Surya Zinc + ZSB (Zinc Solubilizing Bacteria) Bio-Fertilizer
Unlock the hidden wealth of nutrients in your soil with the power of biology.
Surya Zinc + ZSB (by Insecticides India Ltd.) is a revolutionary "Tractor Brand" bio-fertilizer. Unlike traditional Zinc Sulfate which often gets locked (fixed) in the soil and becomes useless, Surya Zinc uses advanced Zinc Solubilizing Bacteria (ZSB). These smart bacteria dissolve the insoluble zinc already present in your soil, making it available to the plant roots. Enriched with elemental Sulfur, it offers a dual-nutrient boost for healthier crops and higher yields.
Best For: Farmers dealing with Zinc deficiency (Khaira disease), stunted growth, and low yields in Paddy, Wheat, and Sugarcane.
Why Choose This Product? Key Benefits
-
⏱️
Unlocks "Fixed" Soil Zinc: Traditional zinc fertilizers have less than 5% recovery efficiency. Surya Zinc releases the 95% of zinc that is currently locked in your soil bank.
-
🛡️
Dual Action (Zinc + Sulfur): Provides both Zinc for growth and Sulfur for protein/oil synthesis, boosting grain quality and oil content.
-
⏳
Long-Lasting Nutrition: Unlike chemicals that wash away, the bacteria colonize the roots and provide a steady supply of nutrients throughout the crop cycle.
-
🌧️
Better Root Development: The bacteria release growth hormones (IAA) that expand the root system, helping plants survive drought and stress better.
-
🌿
Eco-Friendly & Soil Safe: 100% biological and safe. It improves soil health, reduces salinity, and is compatible with organic farming standards.

How It Works: Mode of Action
Surya Zinc works through "Biological Weathering," turning your soil into a nutrient factory.
- Acidification: The bacteria consume organic carbon in the soil and release organic acids (like gluconic and citric acid). These acids lower the pH around the roots, dissolving insoluble Zinc compounds.
- Chelation: The bacteria produce "chelators"—special molecules that act like a claw. They grab the Zinc ions from the soil particles and deliver them directly to the plant roots in a form the plant can easily drink.
- Growth Stimulation: Beyond nutrition, the bacteria produce IAA (Indole Acetic Acid), a hormone that boosts root elongation, allowing the crop to search for water and nutrients more effectively.
Result: Healthier plants, greener leaves, and resistance to deficiency diseases like Khaira.
Target Crops & Pests
| Crop | Target Deficiency / Issue |
|---|---|
| Paddy (Rice) | Khaira Disease (Reddish-brown leaves), Stunted Growth |
| Wheat & Maize | Yellowing between veins, Low grain filling, Low protein |
| Horticulture (Mango/Citrus) | "Little Leaf" disease, Rosette formation, Poor fruit set |
| Oilseeds & Pulses | Low oil content, Poor pod formation (Sulfur deficiency) |
Dosage & Application Guide
The Golden Rule: ZSB needs food to survive! Always mix with Farm Yard Manure (FYM) or Compost when applying to soil.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (Liquid / Granule) | Application Method | Seed Treatment | PHI (Days) |
|---|---|---|---|---|
| Paddy / Wheat | 250-500 ml (Liq) OR 4 kg (Granule) | Soil Broadcast or Drip | 5-10 ml / kg seed | 0 |
| Sugarcane | 500 ml - 1 L (Liq) OR 4 kg (Granule) | Furrow Application / Drenching | Dipping setts | 0 |
| Vegetables | 250 ml (Liq) | Root Dipping / Drip | 10 ml / Litre water (Dip) | 0 |
*PHI = Pre-Harvest Interval: 0 Days because this is a biological product with no chemical residues.
How to Apply: Best Practices
- Timing: Apply as a basal dose during sowing/transplanting or as a top dressing within 45 days of planting.
- Mixing (Soil): Mix the granule or liquid with 50-100kg of Well-Decomposed Farm Yard Manure (FYM) or Vermicompost. This gives the bacteria a home to start multiplying.
- Coverage: Broadcast evenly across the field. Light irrigation after application helps the bacteria penetrate the soil.
- Safety: Do NOT mix with chemical fungicides or antibiotics, as they will kill the good bacteria. Maintain a 5-7 day gap between fungicide sprays and Surya Zinc application.
Frequently Asked Questions
1. Can I use Surya Zinc with Urea and DAP?
Yes, it is generally compatible with Urea and DAP if mixed immediately before application. However, do not leave them mixed for a long time.
2. How is this better than Zinc Sulfate?
Zinc Sulfate often gets fixed (locked) in the soil and becomes unavailable. Surya Zinc unlocks this fixed zinc and provides a continuous supply, offering better value for money.
3. Is it suitable for Organic Farming?
Yes, Surya Zinc + ZSB is a biological input and is generally compliant with NPOP standards for organic farming.
4. Can I mix it with fungicides?
No. Chemical fungicides will kill the live bacteria in the product. Keep a gap of at least 7 days between using a fungicide and this bio-fertilizer.
5. What is the shelf life?
The liquid formulation has a shelf life of up to 2 years, while the powder/granule is best used within 6-12 months. Store in a cool, dry place.
