Biological composition and mycorrhizal symbiosis
- Biological content: Endomycorrhizal fungal propagules (Glomus species) impregnated on a granular carrier.
- Symbiotic relationship: Mycorrhizal hyphae colonize root cortical cells and extend outward into the soil, acting as an expanded root system.
- Nutrient mobilization: Solubilizes and translocates immobile phosphorus, zinc, copper, and iron directly into root vascular bundles.
- Soil structure improvement: Produces glomalin, a biological glycoprotein that binds soil particles into healthy, erosion-resistant aggregates.
Agronomic benefits across field and horticultural crops
- Root biomass expansion: Increases effective root surface area by 100 to 1,000 times, fostering deep anchorage and nutrient uptake.
- Drought and stress resilience: Enhances plant water-use efficiency, sustaining crop turgor during prolonged rainless dry spells.
- Disease suppression: Physio-biologically shields root tips against soil-borne pathogens like Fusarium, Pythium, and Rhizoctonia.
- Target crops: Highly beneficial in sugarcane, cotton, paddy, maize, soybean, vegetables, banana, grapes, and citrus.
Application timing, soil placement, and storage guidelines
- Application method: Broadcast granules evenly at sowing, transplanting, or early vegetative hoeing around the active root zone.
- Dosage discipline: Apply 4 kg per acre per seasonal crop cycle as per manufacturer and biofertilizer guidelines.
- Fungicide caution: Avoid combining with systemic chemical fungicides at the root zone during the first two weeks of inoculation.
- Storage: Store in a cool, shaded environment away from direct heat to preserve living mycorrhizal spore viability.

Common questions
What is Ralligold GR biofertilizer?
Ralligold GR is a mycorrhizal bio-fertilizer that symbiotically colonizes crop roots to enhance nutrient and water absorption.
Which plant nutrient is primarily mobilized by mycorrhiza?
Phosphorus is the primary nutrient mobilized, alongside essential micronutrients like zinc and iron.
When should Ralligold GR be applied to crops?
It should be applied at sowing, transplanting, or early vegetative development in direct contact with root-zone soil.
Can Ralligold GR be used in organic farming?
Yes, mycorrhizal biofertilizers are permitted inputs in certified organic farming systems.
