Invasive Plant Control Database

Welcome to the Invasive Plant Control Database

This website contains information on how to control many invasive plants common to the Midwestern United States. Information was collected from both scientific literature and expert opinions and summarized by the Midwest Invasive Plant Network (MIPN), in partnership with the Mark Renz lab from the University of Wisconsin-Madison. Methods that are uncommon, do not provide sufficient control, or lack information for determining effectiveness on target species are omitted. For each species, information was reviewed by four individuals, including two identified as experts on control of that species. Information is searchable by several fields to improve the user’s ability to find pertinent information. To view the search feature, you must first select an invasive plant. Additionally, users have the option of entering personal experiences with managing specific species (see “add new case studies” under search results). These case studies will be visible to all users once verified by MIPN staff.

We make no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability, or availability with respect to the information or products on the website. Any reliance you place on such information is therefore strictly at your own risk.

Step 2: Select Search Parameters

Step 2: Select search parameter(s) of interest. If no parameters are selected all control methods will be displayed. For effectiveness ratings, methods that meet or exceed the criteria selected will be displayed.

Under the Search Results you will find

  • Plant Identification information – information on species identification, including photographs and a current distribution map.
  • Ecological Threats – threats posed to natural ecosystems by this species.
  • Case Studies – Detailed success (and failures) on how to control specific species contributed by experienced personnel.
  • Non-chemical and chemical control methods that fit the selected search criteria. Please note you are responsible for using pesticides in accordance with the label directions and state and federal laws. Herbicide availability and registered uses vary from state to state. Contact your state department of agriculture for information on the correct use and licensing required for any pesticide application.

You may reset the search criteria or the species you have selected at any time by selecting the corresponding links on the right hand side of the page.

Mowing

User Type -

Effectiveness -

year after treatment
Mowing after flowering stems have elongated, but before flowering will suppress populations as it will prevent plants from producing viable seed, but often plants survive. Typically 2-5 years of mowing is required to reduce population size, but populations will not be eliminated. If areas cannot be mowed, cutting stems and bagging flower heads after blooming is also effective.

Spring burns can kill germinating seedlings and suppress above-ground growth of established plant depending on fire intensity. After the fire, established plants will quickly re-sprout and reinvade areas, therefore this management method is not recommended unless integrated with other techniques. Fire may benefit other species well-adapted to this management (e.g., prairie grasses), resulting in improved competition with dame's rocket. Burns also allow for increased visibility of rosettes for follow-up treatment as they are often one of the first plants to green up after a burn. A hand-held propane torch can be effective for treating seedlings.

Removal

year after treatment
Pulling is effective in eliminating established plants and while effective at any stage, it is easiest to pull just before flowering. For pulling to be effective, the entire taproot must be removed. If flowers are present, bag material and dispose of in a landfill or burn to avoid potential for seed spread. It will take 2-5 years of pulling to suppress populations, but removal rarely controls established populations.

Active Ingredient (A.I.):
2,4-D

Common product name:
Many (Aquatic: DMA 4 IVM; 2,4-D Amine 4)
Rate -
(broadcast) 1 - 2 lb a.e./A
(spot) 0.5 - 0.8% (0.02-0.03 lb a.e./gal)

Timing -
Apply to rosettes in the fall or spring or to flowering plants.

Remarks -
While effective on new infestations, multiple applications will only suppress established populations.

Caution -
Use aquatically labeled product if potential exists for solution to contact surface water. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
imazapic

Common product name:
Plateau
Rate -
(broadcast) 6 - 10 fl oz/A (0.05 - 0.15 lb a.e./A)
(spot) 0.25 - 1% (0.005 - 0.02 lb a.e./gal)

Timing -
Apply to rosettes in the fall or spring or to flowering plants.

Caution -
Do not apply directly to water or to areas where surface water is present. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Imazapic can remain in the soil for months depending on application rate and has the potential to contaminate surface runoff water during this timeframe. Maintenance of a vegetative buffer strip is recommended between the areas Imazapic is applied and surface water features. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
glyphosate

Common product name:

Apply to rosettes in the fall or spring or to flowering plants. Use higher rates when air and soil temperatures drop below 40°F to maintain control.

Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. Applications can result in bare ground as glyphosate is not selective. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants. Rates > fl 16oz/A (0.5 lb a.e./A) may cause stunting and discoloration of sensitive grasses, such as smooth brome. Avoid overspray or drift to desirable plants since even minute quantities of the spray may cause severe injury.
