How It Works: Mode of Action
Nirog works as a "Living Guard" for your crops using three smart strategies:
- The Hunter Strategy (Mycoparasitism): Nirog detects harmful fungi (like Root Rot), wraps around them, and releases enzymes that digest the enemy cell walls, effectively eating them.
- The Starvation Strategy (Nutrient Chelation): It grows faster than pathogens and locks up essential nutrients (like Iron) in the soil, starving the bad fungus so it cannot grow.
- The Barrier Strategy (Antibiosis): It creates a protective "bio-film" around the roots and releases natural antibiotics that stop diseases from entering the plant system.
Result: A healthy root system that absorbs better nutrients and produces higher yields.
Target Crops & Pests
| Crop | Target Pest(s) / Diseases |
|---|---|
| Pulses (Gram, Arhar/Tur) | Fusarium Wilt (Uktha), Dry Root Rot |
| Vegetables (Tomato, Brinjal, Chilli) | Damping Off (Nursery Rot), Bacterial Wilt, Stem Rot |
| Cereals & Cash Crops (Rice, Cotton, Ginger) | Sheath Blight, Foot Rot (Bakanae), Rhizome Rot (Soft Rot) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. For Nirog, the "Incubation Method" (mixing with manure) gives 10x better results than simple spraying.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Application Method | Dose (Total Quantity) | Preparation / Mixing | Dose (per Litre/Kg) | PHI (Days) |
|---|---|---|---|---|
| Seed Treatment (Best for Pulses) | Varies by seed weight | Make a slurry with water + jaggery | 8 - 10 grams / kg seed | 0 |
| Soil Application (Incubation) | 1 - 2 kg / Acre | Mix with 100kg FYM, keep for 3 days | N/A (Soil Mix) | 0 |
| Drenching / Nursery | 500g / Nursery Bed | Mix in water or soil | 10 grams / Litre | 0 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply during the coolest part of the day (early morning or late evening). Avoid direct hot sun as UV rays can kill the fungus.
- Mixing (The Incubation Technique): For best results, mix 2kg Nirog with 100kg Farm Yard Manure (FYM). Sprinkle water, cover with a gunny bag, and leave in shade for 3-4 days before spreading on the field. This multiplies the fungus count.
- Coverage: Ensure the treated manure is mixed into the topsoil where roots grow. For transplants, dip roots in Nirog solution for 15 mins before planting.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Nirog with chemical fungicides?
No. Nirog is a living fungus. Chemical fungicides will kill it. Keep a gap of 7-10 days between applying chemicals and Nirog.
2. What is the shelf life of the product?
The product has a shelf life of 12 months (1 year) from the date of manufacture. Always store it in a cool, dry place away from heat.
3. Is it safe for export crops?
Yes, absolutely. Nirog is 100% biological and leaves no chemical residues, making it perfect for Basmati rice, chillies, and grapes meant for export.
4. Can I use it with fertilizers?
You can use it with organic manures and bio-fertilizers. However, avoid mixing directly with high concentrations of chemical fertilizers (like Urea) in the same tank.
5. How do I know if it is working?
Biologicals work silently. You will notice fewer dying plants, whiter and healthier roots upon inspection, and overall better crop vigor compared to untreated areas.
