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.

Mowing

User Type -

Effectiveness -
in season
year after treatment
Mow three to six times a year for two to four years. After four years >90% of the original population is typically eliminated. The interval between mowing events should be 4 to 8 weeks, depending on the length of the growing season in your area.

Prescribed burning

Effectiveness -

year after treatment
Spring burns can kill germinating seedlings and young plants. Fire can also suppress aboveground growth of established plants depending on fire intensity. After the fire, established plants will quickly resprout and reinvade areas. The removal of the litter layer by the fire can also increase the germination of multiflora rose; this management method is not recommended unless integrated with other techniques. A hand-held propane torch can be effective for treating seedlings and small adult plants (less than or equal to 4' in diameter) in heavy shade.

Removal

User Type -
Novice

Effectiveness -
in season
year after treatment
Pulling or grubbing are effective individual plant treatment if soil conditions allow for the removal of the root crown. Plants will resprout from root crowns if they are left in the ground. Heavy equipment (e.g. bulldozer) can be used to clear severely infested areas as long as the root crowns are removed. When using heavy equipment it may be advantageous to remove the top few inches of soil to remove rose seeds as well. When using these techniques the potential for soil erosion should be assessed as the removal of all vegetation can lead to severe soil erosion. Consider topsoil depth and site topography. Removal of top soil should be followed by the instillation of erosion control structures and reseeding with desirable species as soon as possible.

Grazing

Effectiveness -

year after treatment
Grazing with sheep or goats with or without cattle can help suppress populations. Management prior to grazing (e.g. herbicide application or mowing) is recommended to promote the new young growth preferred by grazing animals. Spring and summer grazing are critical times for rose control. A stocking rate of 10 animals per acre may be needed early in the season, but can be reduced as the season progresses and growth slows. If mature seeds are consumed, animals must be isolated to prevent further spread of seed. Five years of goat grazing are needed to control a population, grazing with only sheep may take longer, but grazing with a combination of all three may increase the effectiveness of control. Cattle will not readily graze multiflora rose, but create paths through the infestation that allow goats and sheep access to plants in dense stands.

year after treatment
There are currently three pests that significantly damage multiflora rose. They are rose rosette disease (RRD), a mite-vectored virus; rose seed chalcid, a torymid wasp that infests and kills developing rose seeds; and rose stem girdler, a beetle whose larvae girdles and kills plant canes. RRD is an unregulated native disease which causes infected plants die within 2-5 years of infection. The rose seed chalcid and rose stem girdler are regulated agents that require permits to introduce. The girdler kills portions of individual canes and does not often kill an entire plant, while the chalcid feeds on and destroys seeds. Biological control agents rarely eliminate entire populations, instead they reduce the cover and seed production. Contact your local department of agriculture for information on permits for the release of biological control agents.

Active Ingredient (A.I.):
Tebuthiuron

Common product name:
Spike 20P; Tebuthiuron 20 P
Rate -
(broadcast) 10 - 20 lb/A (2 - 4 lb a.i./A)
(spot) 1.12 oz/100 sq ft (0.2 oz a.i./100 sq ft)

Timing -
Apply during late winter or early spring when soil is not frozen. Apply evenly to ground infested with target species.

Remarks -
Spike 20P can be used at rates as low as 2.5 lb/A (0.5 lb a.i./A), but partial control should be expected. Tebuthiuron is also available as a liquid formulation, Spike 80DF. This formulation is applied in a banded spray or as a spot treatment.

Caution -
Do not apply directly to water or to areas where surface water is present. Applications can result in bare ground as tebuthiuron is not selective and can remain in the soil for several years depending on application rate. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. In areas fitting this description Spike can be used at rates as low as 2.5 lb/A (0.5 lb a.i./A), but partial control should be expected. Any plant with a root system that intercepts the area treated with this herbicide can be damaged or killed. Do not apply more than 20 lb/A (4 lb a.i./A) a year. Do not apply this product more than once a year.

(spot) Equivalent to broadcast rates.

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

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. Remains in the soil for over one year 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 this product 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. Do not compost treated plants as herbicide can persist through composting process.
