Nirog Bio-Fungicide (Trichoderma Viride 1.5% WP)
The "Probiotic" for Your Soil: Advanced Protection Against Wilt & Root Rot
Nirog (by Insecticides India Ltd.) is a powerful biological fungicide designed to restore health to your soil. Based on the elite IIHR-TV-5 strain, it works like a probiotic, introducing beneficial Trichoderma viride fungus that fights harmful diseases and boosts crop immunity.
Unlike chemical treatments that sterilize the soil, Nirog actively hunts down pathogens like Fusarium and Pythium while helping your plants absorb more nutrients. It is the perfect choice for organic farming and residue-free export production.
Best For: Controlling Wilt, Root Rot, Damping-off, and improving overall soil fertility in all crops.

How It Works: Mode of Action
Nirog uses a "Search and Destroy" biological mechanism to protect your plants:
- Mycoparasitism (The Trap): Nirog wraps around harmful fungi (like Rhizoctonia) and releases enzymes that digest the enemy's cell walls, effectively eating them.
- Nutrient Starvation: It grows faster than pathogens and locks up essential nutrients (like Iron), starving the disease-causing fungus so it cannot grow.
- Induced Immunity (ISR): It signals the plant to boost its own immune system, making the crop stronger against future diseases and environmental stress.
Result: A healthy root zone where pathogens cannot survive.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Pulses (Gram, Pigeon Pea) | Fusarium Wilt (Uktha), Dry Root Rot |
| Vegetables (Tomato, Chilli, Brinjal) | Damping-off (Nursery), Wilt, Root Rot |
| Cash Crops (Cotton, Ginger, Turmeric) | Rhizome Rot, Soft Rot, Root Rot |
Dosage & Application Guide
The Golden Rule: The best results come from Soil Enrichment (mixing with manure) rather than simple spraying.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Application Method | Dose / Acre | Usage Method | Seed / Nursery Dose | PHI (Days) |
|---|---|---|---|---|
| Soil Application (Recommended) | 1 - 2 Kg | Mix with 100kg FYM | - | 0 |
| Seed Treatment | - | Coat seeds uniformly | 8 - 10 g / Kg Seed | 0 |
| Nursery / Root Dip | - | Dip roots before planting | 10 g / Litre Water | 0 |
*PHI = Pre-Harvest Interval: Nirog leaves NO toxic residues. You can harvest immediately after use.
How to Apply: Best Practices
- Timing: Apply during cool hours (early morning or late evening). Avoid direct hot sun as UV light can harm the spores.
- Mixing (The Secret Trick): Mix 1-2 kg of Nirog with 100kg Farm Yard Manure (FYM). Sprinkle water to moisten it, cover with a gunny bag, and keep in shade for 3-4 days. This multiplies the fungus count by billions before you apply it to the soil!
- Coverage: Ensure the mixture reaches the root zone. For drenching, soak the soil around the stem base.
- Safety: Do NOT mix with chemical fungicides. Keep a 7-10 day gap between chemical and Nirog application.
Frequently Asked Questions
1. Can I mix Nirog with other chemical fungicides?
No. Chemical fungicides will kill the beneficial Trichoderma fungus. Always maintain a gap of at least 7-10 days between applying a chemical fungicide and Nirog.
2. Is Nirog compatible with fertilizers and insecticides?
Yes, it is generally compatible with most insecticides and bio-fertilizers. However, avoid mixing it directly with concentrated Urea or DAP solutions.
3. What is the shelf life of the product?
Nirog has a shelf life of 12 months from the date of manufacture. Store it in a cool, dry place to keep the spores alive.
4. Can I use it for organic farming?
Absolutely. Nirog is a biological product and is ideal for organic farming, IPM (Integrated Pest Management) programs, and export-quality crop production.
5. How long does it take to see results?
Since it is a biological agent, it takes a few days to establish in the soil. It works best as a preventive measure or at the very first sign of disease.
