? Coromandel's Cortus: Neem-Enriched Mycorrhizal Biofertilizer
Unlock your soil's potential with **Cortus**, a revolutionary biofertilizer from Coromandel (Gromor Suraksha). This unique formula is enriched with **Neem** to provide a powerful, dual-action solution: drastically **improving nutrient uptake** (especially for Phosphorus) while **protecting roots** from key soil pests. Cortus is your strategic partner for a sustainable, "Future Positive" harvest, ensuring healthier roots, stronger plants, and higher yields.
Cortus addresses the critical "Phosphorus Paradox" in Indian soils by biologically mining the **"Legacy P"** that your crops can't currently access. It’s an essential soil health promoter, building a resilient foundation for your farming success.
Ideal for progressive farmers seeking higher efficiency, better stress tolerance, and reduced chemical input dependency.
Why Choose Cortus? Key Benefits for Your Farm ?
- ⏱️ Maximize Nutrient Uptake Efficiency: The Mycorrhizal fungi act as an **"Extended Root System,"** amplifying the surface area for absorption by up to 1,000 times, significantly enhancing the uptake of **Phosphorus (P)** and **Zinc (Zn)**.
- ?️ Root Protection with Neem Synergy: **Neem Seed Husk** incorporated into the formula helps suppress **soil-borne nematodes** (like Root-knot nematodes), clearing the path for successful mycorrhizal colonization and boosting overall root health.
- ⏳ Built-in Drought and Stress Tolerance: The fungal hyphae access **tightly-held soil moisture** and trigger the plant's **Induced Systemic Resistance (ISR)**, helping your crops better withstand drought and other abiotic stresses.
- ?️ Superior Soil Structure & Water Infiltration: The fungus produces **Glomalin**, a sticky glycoprotein that binds soil particles into stable aggregates, dramatically enhancing soil aeration, water infiltration, and **erosion control**.
- ? High-Quality, Triad Formulation: Formulated with a powerful mix of three highly infective propagules—**Spores, Mycelium, and Colonized Root Bits**—ensuring fast colonization and long-lasting efficacy, exceeding FCO standards.

How Cortus Works: Mode of Action (MoA) in the Root Zone ?
Cortus establishes a powerful **symbiotic relationship** with the crop root, effectively creating a massive underground feeding network that mobilizes locked-up nutrients.
- Early Colonization: Crop roots release signals (**strigolactones**) that trigger the germination of the Spores, Mycelium, and Root Bits in Cortus, guiding the fungus directly to the root surface.
- Internal Arbuscule Formation: The fungi penetrate the root cell walls to form **Arbuscules** (tree-like structures) inside the cortical cells. This is the **nutrient exchange site** where the plant gives sugar and the fungus gives minerals.
- Extended Hyphal Network: An extensive network of **Extra-Radical Mycelium (ERM)** grows far beyond the reach of the root, secreting enzymes (**phosphatase**) to **solubilize fixed Phosphorus (P)** and transport it along with water and micronutrients directly back to the plant via the arbuscules.
The **Neem component** also acts as a nitrification inhibitor, helping to keep nitrogen in the plant-available form ($NH_4^+$) for longer periods, further optimizing nutrient use.
Target Crops & Pests: Where to Apply Cortus
| Crop Category / Crop | Target Pest(s) / Key Benefits |
|---|---|
| Field & Commercial Crops | Improved P-uptake, better tillering, resistance to drought/root stress. (Crops include: Paddy, Wheat, Maize, Cotton, Soybean, Sugarcane) |
| Vegetables & Chilli | Minimizes transplant shock, Neem-action helps control Root-knot Nematodes, enhanced fruit setting. (Crops include: Tomato, Chilli, Brinjal) |
| Horticulture & Plantation | Stronger perennial root systems, enhanced moisture scavenging during dry periods, long-term P mobilization. (Crops include: Citrus, Mango, Banana, Pomegranate, Coffee, Tea) |
Dosage & Application Guide: How to Use Cortus Effectively
The Golden Rule: Always follow the **"Dose per Acre"** for accurate results. Cortus must be applied **basally** (at planting/sowing) for maximum effectiveness.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (Kg / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Field Crops (Paddy, Maize, Cotton) | 4 Kg | 200 L | 20 g | NA |
| Horticulture (Vegetables, Chilli) | 4 Kg | 200 L | 20 g | NA |
| Plantation Crops (Mango, Citrus) | 8 Kg | 400 L | 20 g | NA |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. NA for Biofertilizer as it has no residue.
How to Apply: Best Practices for Biofertilizer Use
- Timing is Crucial (Basal Application): Apply Cortus at **sowing, planting, or transplanting**. This ensures the mycorrhiza establishes the symbiosis with the emerging root for the entire life of the crop. Application in the early vegetative stage (15-30 days) is the second-best option.
- Mixing for Uniformity (Broadcasting): Mix the recommended dosage of Cortus (WP) with **50-100 kg of Farm Yard Manure (FYM)**, vermicompost, or dry soil. This "bulking up" step guarantees an even spread of the inoculum across the field before the final plowing.
- Water Suspension (Drenching): For individual plants (Horticulture/Plantation), create a water suspension and apply it directly around the plant's **root basin (ring method)**. Use enough water (e.g., 20 g/L) for the suspension to reach the root zone.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions (Cortus Biofertilizer)
1. Is Cortus compatible with chemical fertilizers like DAP and Urea?
**Yes, it is compatible.** Cortus works best in a comprehensive nutrient management program. The fungi are selected to tolerate standard agricultural NPK levels.
2. Can I mix Cortus with a fungicide? ?
**No, absolutely not.** Fungicides are designed to kill fungi and will destroy the active mycorrhiza in Cortus. If you must use a soil fungicide, apply it first, and wait 7-10 days before applying Cortus.
3. What makes Cortus different from other mycorrhizal products?
The key difference is the **Neem Seed Husk Enriched Wettable Powder (WP) formulation**. This provides dual benefits: superior nutrient mobilization (mycorrhiza) + root protection from nematodes (neem), a unique selling proposition.
4. Why is the dosage higher for plantation crops?
Perennial crops like Mango or Citrus have massive, established root systems. The higher **8 Kg/acre** dosage ensures a sufficient inoculum load to colonize the entire, extensive rhizosphere and provide long-term benefits.
5. Is Cortus safe for the environment?
**Yes.** As a bio-product, Cortus is non-toxic, non-polluting, leaves no harmful residues (NA PHI), and actively improves soil biodiversity and structure.
