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.

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.

Case Studies
Description
Treatment Description -
Heavy infestation of Sericea lespedeza on 67 acres of CRP. Herbicide was applied early in the month of September(late summer) after plants had reached flowering stage. 1 oz Escort XP(Metsulfuron methyl) with 4 oz Ag Edge Methyl Ester Adjuvant per Acre.

Habitat Type -
Application took place in Stoddard Co Missouri. Habitat type would be considered old field/ grassland.

Effectiveness -
95-98% of the parent plants were control in the year of application. The year after application, the site still exhibited over a 95% control rate with very few new plants. No resprouts were found on the site, even in areas which previously had heavy infestations.

Mowing

Effectiveness -

year after treatment
Mowing during the flower bud stage, but before seeds are formed can suppress lespedeza. Monitor populations and repeat mowing each time target plants reach 12-18" in height. Two or three years of mowing typically suppresses established populations. Take care not to mow when mature seeds are present to avoid seed spread.

Prescribed burning

User Type -
Professional

Effectiveness -
in season
year after treatment
Spring burns can kill germinating seedlings and can suppress aboveground growth of established plants depending on fire intensity. After the fire, there may be a flush of new growth as seeds are scarified by fire and established plants will quickly resprout and reinvade areas. Summer burns, when lespedeza has begun to flower, is most effective for suppression. However, summer burning can adversely affect desirable species. Neither timing is 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 lespedeza. A hand-held propane torch can be effective for treating seedlings.

Removal

User Type -

Effectiveness -
in season
year after treatment
Pulling when soil conditions allow for the removal of the entire root is an effective single plant control technique. This is most appropriate for seedlings and young plants as older plants develop a deep taproot. If seeds are present, bag material and dispose of it in a landfill to avoid potential for seed spread.
Type -
Grazing

User Type -
Novice

Effectiveness -
in season
year after treatment
Cattle only forage on early growth, but can suppress lespedeza under high stocking rates, especially after a spring burn. Goats browse lespedeza and can eliminate adult plants in a population after 3 years of grazing under heavy stocking rates. Goats severely suppress seed production as well. Viable seeds can pass through the digestive system of grazers; confine grazing stock until all seed has passed before moving stock to new areas.

Timing -
Apply when target species is actively growing and fully leafed out. Applications during the flower bud stage are most effective.

Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. 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.
