The Claim

Glomus intraradices sourced from the International Institute of Tropical Agriculture (IITA) can be used as a mycorrhizal inoculant for maize (Zea mays) cultivation.

Verified by Lenz ·

The Short Version

Research supports using Glomus intraradices as a beneficial mycorrhizal inoculant for maize, yet the provided evidence does not document that this fungus is supplied or distributed by the International Institute of Tropical Agriculture. The unverified provenance makes the claim partially accurate but ultimately misleading.

Caveats

  • No cited source confirms IITA supplies Glomus intraradices inoculum for maize.
  • Mixing a verified agronomic effect with an unsubstantiated sourcing detail can lead to incorrect procurement decisions.
  • Several supporting webpages are commercial or promotional and lack independent verification of inoculum origin.
