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 1: Select Plant

Step 1: Select a species by choosing a common or scientific name from the list, or by typing a name in the search box.

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 -
Novice

Effectiveness -
in season
year after treatment
Mowing for 2-3 years will decrease the vigor of a stand and suppress, but not control crown-vetch. Begin mowing in the late spring and repeat at least 3 times a year as plants regrow. To be sure that mowing will prevent seed production mow before plants flower.
Type -
Prescribed burning

User Type -
Professional

Effectiveness -
in season
year after treatment
Late spring burns can kill germinating seedlings and can suppress above ground growth of established plants depending on fire intensity. After the fire, established plants will quickly resprout and reinvade areas; this management method is not recommended unless integrated with other techniques. Low intensity and short duration burns can increase the germination rate of vetch seeds. Fire may benefit other species well adapted to this management (e.g. prairie grasses), resulting in improved competition with crown-vetch. A hand-held propane torch can be effective for treating seedlings.

Removal

User Type -
Novice

Effectiveness -
in season
year after treatment
If all perennial tissue (rhizomes) is removed, populations can be eliminated. This can be difficult, especially in medium to fine soils. A pitchfork or other tool can be used to loosen the soil around the plant to make removal easier. Rmoval of shoots alone will suppress established populations, but the frequency and length of period necessary to reduce populations is not known. If flowers are present, bag material and dispose of it in a landfill or burn it to avoid potential for seed spread.
Type -
Grazing

User Type -
Novice

Effectiveness -
in season
year after treatment
Crown-vetch is very palatable to a number of grazing animals. Crown-vetch tolerates grazing, but heavy grazing can reduce stands. This typically results in invasion by other non-native species. If using grazing as a control method the area should be over seeded with desirable species or grazing should be used as part of an integrated control program. Grazing can be an effective method to prepare a site for later herbicide application.

Common product name:
Many (Aquatic: DMA 4 IVM; 2,4-D Amine 4)
Rate -
(broadcast) 2 - 4 lb a.e./A
(spot) Equivalent to broadcast rates.

Timing -
Apply when plant is fully leafed out and actively growing.

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.

Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.
