In areas where garlic mustard is invasive, garlic mustard inhibits the growth of a fungus required by most native plants, resulting in a garlic mustard desert.  GM does this by producing and releasing the allelopathic chemical benzyl isothiocyanate (BITC), which inhibits the growth of ectomycorrhizal fungi, required by the native plants' roots, via a symbiotic relationship.

Garlic mustard was brought to North America by 👥︎ ⛵︎ European settlers, who used it as a 🍲︎ "pot herb" or green in stews, early in the growing season, when it is the only green available.  Later, it escaped into the wild, and people forgot how to cook with it.  Recently, some are rediscovering how to do so.  This author has tasted a pesto made in the local 🏫︎ Middle School — very tasty.  recipes story and recipe recipe book Pest to Pesto 2
