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 - 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 can suppress aboveground 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. Fire may benefit other species well adapted to this management (e.g. prairie grasses), resulting in improved competition with bindweed. A hand-held propane torch can be effective for treating seedlings.
Type - Removal User Type - Novice Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Pulling and digging are effective techniques for individual plant control if all perennial roots are removed from the soil. This is difficult unless plants are establishing or soil is amenable to pulling. These techniques should be implemented before plants flower.
Type - Manipulation of the environment User Type - Novice Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Competition by grasses and other robust species that maximize shading can suppress field bindweed. Litter will also reduce field bindweed germination and shoot growth.
Type - Cultivation User Type - Novice Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Intensive cultivation controls newly emerged seedlings and may reduce established populations especially if integrated with other control methods. Timely cultivations every 1-2 weeks, beginning when the plant is in the bud stage, but before any flowers open, will deplete the root reserves of established plants and after several years eradicate populations. Cultivation, however, can spread roots into previously uninfested areas. When pairing cultivation with herbicide treatments, delay cultivation for at least 7 days after herbicide application.

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.): oryzalin Common product name: Surflan AS; Quali-Pro Oryzalin 4	Rate - (broadcast) 64 - 192 fl oz/A (2 - 6 lb a.e./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 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.): prodiamine Common product name: Barricade; Evade 4 FL	Rate - (broadcast) 21 fl oz/A (0.65 lb a.i./A) (spot) 0.5 fl oz/1000 sq ft (0.02 lb a.i./1000 ft2) 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. 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. This herbicide should be incorporated as it is applied and must be incorporated within 24 hours of 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 - Novice Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	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) For a 3.8 lb a.e./gal product. 0.5 - 0.8% (0.02 - 0.03 lb a.e./gal) Timing - Apply from bud to full bloom stage when stems are at least 12" long. 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.
Type - Foliar User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): dicamba Common product name: Banvel; Clarity	Rate - (broadcast) 16 - 32 fl oz/A (0.5 - 1 lb a.e./A) (spot) Equivalent to broadcast rates. Timing - Apply from bud to full bloom stage when stems are at least 12" long. 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. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants. Rates > 16 fl oz/A (0.5 lb a.e./A) may cause stunting and discoloration of sensitive grasses, such as smooth brome.
Type - Foliar User Type - Professional Effectiveness - in season 1 2 3 4 year after treatment 1 2 3 4	Active Ingredient (A.I.): fluroxypyr Common product name: Vista XRT; Starane Ultra	Rate - (broadcast) 8 - 16 fl oz/A (0.18 - 0.35 lb a.e./A) (spot) 0.14 - 0.30% (0.004 - 0.008 lb a.e./gal) Timing - Apply from bud to full bloom stage when stems are at least 12" long.
