MycoApply® Injector Ecto is a concentrated suspendable powder that contains propagules of multiple species of ectomycorrhizal fungi on a soluble humic carrier. The ectomycorrhizal fungi colonize the root systems of plants in a symbiotic manner, expand out beyond the plant roots or rhizosphere region of the soil surrounding the plant roots to acquire nutrients and water, and actively deliver these resources to the plant’s vascular system.
