Pulling is more effective if the entire root is removed and desirable plants and soils are not trampled and compacted. The University of Georgia - Center for Invasive Species and Ecosystem Health. , Garlic mustard produces a variety of secondary compounds including flavonoids, defense proteins, glycosides, and glucosinolates that reduce its palatability to herbivores. Additional research was requested by TAG in response to the 2008 petition. , The example of garlic mustard shows how effective, at least in Minnesota's controlled trials and European field observations, even one monophagous biological control agent can be, while having the fewest costs. Garlic mustard is difficult to control once it has reached a site. , The most promising biological control agent, the monophagous weevil C. scrobicollis, specifically studied since 2002, has been blocked for introduction into the US repeatedly by the USDA Technical Advisory, TAG, group, despite researchers' many petitions for approval.  The flowers increase visibility, especially in lower light situations.  Seeds are also easily tracked around by animals, vehicles, and people. USDA Forest Service - Northeastern Area.

Munching on Garlic Mustard - A New Weevil in the Works.  Despite the demonstrated effectiveness of C. scrobicollis and, potentially, C. constrictus, the importation and release of biological control agents such as those may be stymied by heavy research and regulation requirements. Garlic mustard (Alliaria petiolata) is an invasive herb that has spread throughout much of the United States over the past 150 years, becoming one of the worst invaders of forests in the American Northeast and Midwest. Root breakage is most common in soil compacted by foot traffic and in drier conditions.

Michigan State University. ... pushing native plants back and reducing diversity among native species. It is found in forested areas. Garlic mustard grows in a wide range of habitats and spread quickly along roadsides, trails, and fence lines. ARS.  For the management of some invasive plants, or in some cases when dealing with garlic mustard, herbicide application and human-managed labor such as mowing, tilling, burning, and pulling may be preferred for managing unwanted vegetation on land that is highly disturbed by human activity, such as agricultural land. Kokron. Unfortunately, non-native invasive species, including garlic mustard (Alliaria petiolata), have also populated these areas and pose a threat to the multiple ecosystems within Ann Arbor’s borders. This invasive plant can be found all across Indiana and is hard to get rid of, like most invasive species. By contrast, nothing eats it to a significant extent in the United States where it is non-native. Therefore, management by planting or encouraging other plants to intercept light will not prevent new infestations, although it may slow them. For more complex ecosystems such as forests, trampling and other physical disturbance such as soil compaction, the spreading of seeds from clothing, chemical toxicity, unwanted non-targeted species damage, demanding human labor, petrochemical consumption, and other factors are eliminated or greatly reduced with effective biological control.

Garlic mustard has been researched by the United States since the 1990s and C. scrobicollis has been studied specifically since 2002. It is illegal to import, sell or transport propagating parts.  However, allelochemicals produced by garlic mustard do not affect mycorrhizal fungi from garlic mustard's native range, indicating that this "novel weapon" in the invaded range explains garlic mustard's success in North America.  Those who believe the regulations are well-crafted argue they are needed to prevent the agents from becoming highly undesirable pests while critics argue that the regulations, as currently written and implemented, make it too difficult to bypass more damaging, less effective, and more costly methods of control â such as applying herbicides in forests. Garlic mustard is on the Restricted weed list. 2009.  The persistence of the seed bank and suppression of mycorrhizal fungi both complicate restoration of invaded areas because long-term removal is required to deplete the seed bank and allow recovery of mycorrhizae. animal species living among the unde-veloped parkland.

Reasons Why it has Become Established: The success of garlic mustard as an invasive species seems to be related to: the absence of natural enemies in North America, it's ability to self fertilize, high production of 15,000 seeds annually, rapid growth during the second growing season, and the release of phytotoxins from its root tissue. Monophagous controllers, such as the weevil C. scrobicollis, which only feeds on garlic mustard, are usually the most ideal candidates for initial introduction to combat invasive plants, as they greatly reduce the chance that the introduced controller will itself become a pest.  As of May 2017, there is no legally-approved biological control agent to combat garlic mustard in the United States. Biological Control Journal. Katovich, J., Gerber, E., Hinz H., Skinner, L., Ragsdale, D., Becker, R., 2007. Similar Species .

Garlic mustard is single-stalked plant, which typically grows to about 3 feet tall with small white flowers near the top.  In northeastern forests, garlic mustard rosettes increase the rate of native leaf litter decomposition, increasing nutrient availability and possibly creating conditions favorable to garlic mustard's own spread. Garlic mustard is highly invasive and threatens the abundant wildflowers and diverse forest ecosystem of West Virginia, Virginia, Ohio, Indiana, and Illinois. It is also toxic to some native insects, such as North American butterflies in the genus Pieris such as Pieris virginiensis and Pieris oleracea. Biological Control.

Background. “As some invasive species become established, they create a positive feedback loop, altering soil chemical properties through allelopathic traits, building up a seed bank and so on. These plants produce many small seeds which can be spread by wind or be transported by human activities. In the following year, the mature plants produce a flower spike up to one metre tall. Columbia University. The monophagous weevil C. scrobicollis, studied since 2002, was officially recommended for introduction into the US in 2012 but the TAG group blocked its introduction, requesting further research be conducted. Surviving roots regrow and produce new seed pods, enabling the infestation to potentially be quickly reestablished. United States Department of Agriculture - AgResearch Magazine. All non-biological methods of control must be repeated for 2â5 years to be effectiveâas most infestations occur in sites where a considerable seed bank has been established. Garlic mustard is an invasive herb native to Europe. Garlic mustard seedlings can be confused with the basal leaves of … Wright State University.  Difficulties involved in using biological control are identifying species that are safe to introduce as well as relying on fewer controlling species being present in the non-native ecosystem. Before sharing sensitive information online, make sure you’re on a .gov or .mil site by inspecting your browser’s address (or “location”) bar. , Garlic mustard produces allelochemicals, mainly in the form of the compounds allyl isothiocyanate and benzyl isothiocyanate, which suppress mycorrhizal fungi that most plants, including native forest trees, require for optimum growth.

Garlic mustard can invade stable forests as well as disturbed sites. , Of the 76 natural enemies garlic mustard has in its native range, several have been tested for use as potential biological control agents. Accurately targeted biological control is the method of control that is the least-damaging to ecosystems not typified by monoculture, like forested areas, while also being the most efficient in terms of costs. In some woodlands, dense stands of garlic mustard in the spring threaten showy spring blooming ephemerals like spring beauty, trilliums and trout lilies.
