Biological composition and mycorrhizal mechanism
- Contains active propagules (spores, mycelial fragments, infected root pieces) of beneficial endomycorrhizal fungi (Glomus species).
- Symbiotic partnership: Fungal hyphae penetrate root cortical cells while extending outward through soil, increasing the effective root absorption area by 100 to 1,000 times.
- Phosphorus solubilization: Secretes organic acids and phosphatase enzymes that solubilize fixed, immobile soil phosphorus into plant-absorbable orthophosphate.
- Enhances the uptake of vital micronutrients including zinc, iron, copper, and manganese from deep soil layers.
Agronomic benefits across cropping systems
- Drought resilience: Fungal hyphae extract moisture from microscopic soil pores beyond the reach of normal plant root hairs, shielding crops from moisture stress.
- Root disease suppression: Mycorrhizal colonization forms a physical barrier that helps suppress soil-borne pathogens like Fusarium, Pythium, and Rhizoctonia.
- Improves transplant survival in vegetables, fruit orchards, sugarcane, and nursery plantations.
- Enhances soil aggregation and structure by secreting glomalin, an organic soil-binding glycoprotein.
Application methods and precautions
- Granular application: Mix with well-rotted farmyard manure, vermicompost, or soil and apply at planting or basal fertilizer placement.
- Drip fertigation / Drenching: Soluble formulations can be applied through drip systems into the root zone of standing crops.
- Avoid direct contact with chemical systemic fungicides during application to ensure mycorrhizal fungal spore viability.

Common questions
What is Tata Ralligold?
It is a mycorrhizal (VAM) biofertilizer that expands root surface area and enhances nutrient and water absorption.
How does mycorrhiza improve phosphorus uptake?
Mycorrhizal hyphae extend into the soil and secrete enzymes that release fixed, insoluble soil phosphorus.
How is Tata Ralligold applied in the field?
It can be applied as granules mixed with compost at planting, or through drip fertigation in soluble form.
Can chemical fungicides be mixed with Tata Ralligold?
No, avoid mixing directly with synthetic chemical fungicides, as they can kill beneficial mycorrhizal fungi.
