  Wallace Organic Wonder Mycorrhizal Inoculant is a super - concentrated organic, single species of Endo Mycorrhizal Fungi containing only Rhizophagus Intraradices.  Why “Endo?”  Because Ecto Mycorrhizae have NO BENEFICIAL effect on any vegetables, fruits, flowers or herbs. Ecto Mycorrhizae are used on Conifers  (cone-bearing) and Oak trees.  Why does Wallace Organic Wonder only use "Single Species Endo Mycorrhizae?"Because single species Rhizophagus Intraradices (Endo Mycorrhizae) outperform all other species in a nutrient and organic environment, eliminating rootzone competition, and are the fastest and most aggressive colonizing mycorrhizae in the world.  Adding Trichoderma and other microbes into a product is not advised as NOT all organisms get along.
