Pinot noir grapevines were planted and inoculated with MycoApply® Endo-granular in early summer, 2019. MycoApply® Endo is a granular product containing 4 species of fungi (Glomus intraradices, Glomus mossae, Glomus aggregatum, and Glomus etunicatum). The purpose was to evaluate the proposed benefits of the commercially sold fungi and differences between two rootstocks compared to the control. The experiments were conducted in the Finger Lakes AVA at Lansing, NY Cornell University vineyard. The inoculation treatments resulted in greater root length colonization by AMF, but there were no apparent benefits to the vine.dissertation or thesis
