Benefits

Improved Stress Tolerance

Enhances resilience to drought and salinity by improving water retention, regulating osmotic balance, and supporting antioxidant defense mechanisms, helping plants survive in harsh conditions.

Stronger Root System

Promotes root elongation and branching, increasing root surface area for better nutrient and water absorption, ultimately improving plant stability and growth.

Better Soil Health

Produces glomalin, a glycoprotein that binds soil particles, enhancing soil aggregation, aeration, and microbial interactions, contributing to long-term soil fertility.

Enhanced Nutrient Uptake

Extends its hyphal network beyond the root zone, significantly improving phosphorus, zinc, and other micronutrient absorption, leading to better plant nutrition.

Mode of Action

Glomus mosseae establishes a beneficial relationship with plant roots through a series of well-coordinated steps:

Symbiosis Establishment: The process begins when spores of F. mosseae in the soil germinate, sending out hyphae (fungal filaments). These hyphae grow towards plant roots, stimulated by chemical signals (like strigolactones) released by the roots.10 Upon reaching a compatible root, the hypha forms an appressorium (a swelling) on the root surface, allowing it to penetrate the root epidermis and cortex.
Inside the root cortical cells, the fungus develops highly branched structures called arbuscules.
Many AMF, including F. mosseae, also form vesicles, which are oval, lipid-filled structures within the root that serve as storage organs for the fungus.
Nutrient Exchange and Plant Benefits: Arbuscules are the primary sites of nutrient exchange.The extensive network of extraradical hyphae extends far into the soil, beyond the reach of plant roots, efficiently absorbing nutrients and water.
Phosphorus (P): G. mosseae significantly enhances P uptake, making it more available to plants, especially in P-deficient soils.
Nitrogen (N): It improves N acquisition by absorbing ammonium and nitrate, and potentially organic N forms.
Other Nutrients: Uptake of potassium (K), magnesium (Mg), calcium (Ca), and micronutrients like zinc (Zn), copper (Cu), iron (Fe), and manganese (Mn) is also enhanced.41
Water: The hyphal network increases the surface area for water absorption, improving plant water relations and drought tolerance.1
In return for these nutrients, the plant provides the fungus with carbon compounds (sugars and lipids) derived from photosynthesis.1
Soil Health Improvement: The extraradical hyphae of F. mosseae bind soil particles together. The fungus also secretes glycoproteins like glomalin, which act as a soil glue, promoting the formation and stability of soil aggregates. This improves soil structure, aeration, water infiltration, and reduces erosion.
Stress Tolerance: F. mosseae significantly enhances plant resilience to various abiotic stresses:
Drought Stress: By improving water uptake and physiological responses like osmotic adjustment.1
Salinity Stress: By aiding in osmoregulation and potentially reducing toxic ion uptake.37
Heavy Metal Stress: By immobilizing metals in the roots or soil, reducing their translocation to shoots, and enhancing plant antioxidant systems.

Disease Resistance: G. mosseae can enhance plant resistance to certain soilborne pathogens. This can occur through competition for root space and nutrients, improved plant vigor, and by inducing systemic resistance in the host plant (Mycorrhiza-Induced Resistance).

Additional Info

Handling Information

Storage: Store inoculants in a cool, dry place, away from direct sunlight and extreme temperatures to maintain propagule viability.63 Refer to product label for specific storage recommendations and shelf-life.
Precautions: Avoid inhaling dust from powder formulations. It is advisable to wear gloves and wash hands thoroughly after handling any microbial inoculant. Keep out of reach of children and pets.

Safety Information

Glomus mosseae is a naturally occurring soil microorganism and is generally considered safe for humans, animals, and the environment when used as directed.
It is an eco-friendly component of sustainable agricultural systems.
Not intended for human or animal consumption.

Dosage & Application

Glomus mosseae inoculants can be applied through various methods depending on the crop, cultivation system, and product formulation:

Seed Treatment: Inoculum can be coated onto seeds before sowing. This ensures the fungus is present when roots emerge.
Soil Application: Inoculum (powder, granular, or liquid) can be incorporated into the soil or planting medium at the time of sowing or transplanting, applied in furrows, or mixed with nursery substrates.
Root Dipping: Seedling roots can be dipped into a slurry of the inoculum before transplanting.
Nursery Application: Incorporating inoculum into nursery beds or potting mixes helps produce mycorrhizal seedlings that are more robust and perform better after transplanting.
