Q. You have written about using cornmeal for toenail fungus. According to Bob Webster, a South Texas gardening expert, the reason ground cornmeal works against fungus (including grass fungus as well as foot fungus) is because a fungus called Trichoderma grows on cornmeal.
Trichoderma attacks and destroys other non-beneficial fungi. Bob Webster recommends covering the fungus-affected area with cornmeal paste for one hour each day for 7 to 10 days. It works!
A. We’ve always wondered why cornmeal might fight nail fungus and are grateful for the explanation. There are more than 80 species of Trichoderma; the one used to control fungi that attack plants is T. harzianum. It grows especially well on cornmeal.
