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.

Non-Chemical controls

New (Type)	Description
Type - Mowing User Type - Novice Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Mow or cut plants as close to the ground as possible in late summer or early fall after flowering, but before seeds are present. Monitor the site a week after initially mowing to identify plants that were not cut and remove them before they produce seeds. Continue to monitor the site for at least seven years to ensure that the seed bank is exhausted. If plants are cut earlier this can result in cut plants regrowing and flowering earlier than they would if left undisturbed.
Type - Prescribed burning User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Spring burns can kill germinating seedlings and suppress aboveground growth of established plants depending on fire intensity. However, stiltgrass seeds in the seed bank will germinate soon after the fire and reinfest areas. Fall burns are preferred as long as they are timed before seed set, as they remove the heavy mats of vegetation that stiltgrass produces and prevent seed production. This can result in improved cover of desirable understory species the following growing year. A hand-held propane torch can be effective for treating seedlings and adult plants.
Type - Removal User Type - Novice Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Pulling is an effective treatment for individual plants throughout the year, but is usually easiest in the late summer to early fall when plants are larger. Pulling will disturb the soil and can possibly expose stiltgrass seeds in the soil. Pulling later in the growing season will provide less time for seeds in the soil to germinate and reproduce. Pulling should be repeated for at least seven years to ensure the seed bank is exhausted. Bag and dispose of material in a landfill, since plants can root from the nodes and seeds are easily spread.
Type - Manipulation of the environment User Type - Novice Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Flooding for more than three months or intermittent flooding during the growing season can control adult stiltgrass, but seeds can survive up to 10 weeks of constant flooding.

Chemical controls

New (Type)	Ingredients	Directions
Type - Pre-emergence User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): dithiopyr Common product name: Dimension	Rate - (broadcast) 1.25 lb/A (0.5 lb a.i./A) Timing - Apply prior to germination of seedlings. While spring applications will maximize control, fall or winter applications may also suppress seedlings the following spring, depending upon environmental conditions. Remarks - Reduced efficacy can be expected if <0.5" of rainfall occurs before target species germinates. Caution - Do not apply directly to water or to areas where surface water is present. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.
Type - Pre-emergence User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): oryzalin Common product name: Surflan; Quali-Pro Oryzalin 4	Rate - (broadcast) 64 - 96 fl oz/A (2 - 3 lb a.i./A) (spot) Equivalent to broadcast rates. Timing - Apply prior to germination of seedlings. While spring applications will maximize control, fall or winter applications may also suppress seedlings the following spring, depending upon environmental conditions. Remarks - 64 fl oz/A will provide 2-4 months of control. 192 fl oz/A will provide 8-12 months of control. Wait 2 months between applications at the 64 fl oz rate, wait 8 months between applications at the 192 fl oz rate. Caution - Do not apply directly to water or to areas where surface water is present. Applications can result in bare ground as oryzalin can lose selectivity if applied at higher rates and can remain in the soil for several months depending on application rates. Overspray or drift to desirable plants should be avoided as even minute quantities of the spray may cause severe injury to plants.
Type - Pre-emergence User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): pendimethalin Common product name: Pendulum Aquacap; Prowl	Rate - (broadcast) 100 - 134 fl oz/A (3 - 4 lb a.i./A) Timing - Apply prior to germination of seedlings. While spring applications will maximize control, fall or winter applications may also suppress seedlings the following spring, depending upon environmental conditions. Remarks - Reduced efficacy can be expected if <0.5" of rainfall occurs within 30 days of application. Caution - Do not apply directly to water or to areas where surface water is present. Do not exceed applications of 67 fl oz/A on home lawns, parks, schools, and playgrounds. Overspray or drift to desirable plants should be avoided as even minute quantities of the spray may cause severe injury to plants.

While spring applications will maximize control, fall or winter applications may also suppress seedlings the following spring, depending upon environmental conditions. Caution - Do not apply directly to water or to areas where surface water is present. Overspray or drift to desirable plants should be avoided as even minute quantities of the spray may cause severe injury to plants. Do not apply more than 48 fl oz/A per year.
Type - Pre-emergence User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): trifluralin Common product name: Trifluralin HF; Treflan HFP	Rate - (broadcast) 16 - 32 fl oz/A (0.5 - 1 lb a.i./A) (spot) Equivalent to broadcast rates. Timing - Apply prior to germination of seedlings. While spring applications will maximize control, fall or winter applications may also suppress seedlings the following spring, depending upon environmental conditions. Remarks - Use higher rates in finer soils. Sprinkle on soil, but keep granules away from plant roots and foliage. Water-in or lightly rake-in immediately after application. Caution - Do not apply directly to water or to areas where surface water is present. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.
Type - Foliar User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): clethodim Common product name: Envoy; Select Max	Rate - (broadcast) 12 - 16 fl oz/A (0.09 - 0.12 lb a.i./A) (spot) 0.33 - 0.66% (0.003 - 0.006 lb a.i./gal) Timing - Apply any time during the summer, but before seeds are produced. Two applications during the growing season are recommended. Caution - Do not apply directly to water or to areas where surface water is present. Overspray or drift to desirable grasses should be avoided, as even minute quantities of the spray may cause severe injury to grasses.
Type - Foliar User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): fluazifop Common product name: Fusilade	Rate - (broadcast) 16 - 24 fl oz/A (0.25 - 0.4 lb a.i./A) (spot) 0.5% (0.01 lb a.i./gal) Timing - Apply any time during the summer, but before seeds are produced. Two applications during the growing season are recommended. 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. Fluazifop can remain in the soil for one to two 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 fluazifop is applied and surface water features. Overspray or drift to desirable grasses should be avoided, as even minute quantities of the spray may cause severe injury to grasses.
