Transcript of Garlic Mustard
Alliaria petiolata Where is Garlic Mustard originally from?
Native to Europe and was first introduced into New England during the 1800's for medicinal and culinary purposes
Native range: Africa, temp. and trop. Asia, Europe Where has it been introduced?
Garlic mustard is mainly found in the northeast part of the United States and in the mid-west, along the Great Lakes.
Europe (England to Sweden), western regions of Russia, India, Sri Lanka, south to Italy and Mediterranean basin
New Zealand, Canada, and the United States When was it introduced?
-Garlic mustard was introduced into New England during the 1800s for medicine, food, and/or culinary processes What types of habitats does it invade?
-Moist shaded soil of river floodplains, wooded areas, roadsides, and edges of woods and trials. Also may invade other habitats but usually does NOT tolerate habitats of high acidity. What environmental problems is it causing?
Garlic Mustard is one of the few invasive species that can
invade and dominate the understory of forested areas. Garlic Mustard
can outcompete native plants for sunlight, soil, nutrients, and space.
The article we all read also mentioned a chemical that can inhibit EM
fungal growth which native plants use to survive. Many animals that rely on native plant species for food are harmed when Garlic Mustard grabs hold of an area. Is the organism creating an economic cost?
Garlic Mustard contributes to an estimated $32 billion annual
cost from invasive species through water contamination, soil loss,
decreased land value, control cost, competition with crops and
diminished food quality, and losses to non-crop ares. We don't know
the exact economic cost but since Garlic Mustard can spread 4,600
acres a day it is sure to be a lot. What are the recommended control practices?
Long-term eradication can take up to 3-5 years. The three main ways currently used to control this invasive species are pulling, burning and herbicides. All three have drawbacks: pulling is labor intensive, buring can be dangerous, and herbicide use can lead to resistance. Strange Factoids:
Garlic Mustard is also harmful to a few species of butterfly. It is harmful in two ways, first they replace the native food source when they take over an area and are toxic to butterfly eggs when laid on Garlic Mustard leaves.
Garlic Mustard does not tolerate acidic soils or warm environments
It was first brought to New York and its spread has been reported as far west and north as Alaska The Three Things You Need To Know
1. It can take 3-5 years to eradicate Garlic Mustard from an area
2. Originally brought to the U.S. to be used as food and medicine
3. Can completely invade the understory of a forest within 2-3 years
