Canada thistle is a serious weed of many crop, rangeland, pasture, and natural areas throughout North America. Aminopyralid is a new pyridine carboxylic acid herbicide that has activity on Canada thistle at lower use rates than current standard treatments. The objectives of this study were to compare aminopyralid efficacy, rates, and application timing with several commercial standards for Canada thistle control. Studies were conducted across the Great Plains at ten locations, which encompassed… 
Russian Knapweed (Acroptilon repens) Control with Low Rates of Aminopyralid on Range and Pasture
TLDR
Aminopyralid controlled Russian knapweed effectively at lower use rates than current commercial standards and good control lasted for at least 21 to 24 MAT.
Effect of Aminopyralid on Canada Thistle (Cirsium arvense) and the Native Plant Community in a Restored Tallgrass Prairie
Abstract Aminopyralid efficacy on Canada thistle (Cirsium arvense) and potential to injure native species was evaluated in a restored prairie at the Glacial Ridge Preserve managed by The Nature
Aminopyralid and Clopyralid Absorption and Translocation in Canada Thistle (Cirsium arvense)
TLDR
The results suggest that aminopyralid's chemical structure may provide for greater biological activity at the target site than clopyralids.
Control of Silky Crazyweed (Oxytropis sericea) with Aminopyralid + 2,4-D and Picloram + 2,4-D on Native Rangeland
TLDR
Silky crazyweed is a widely distributed and economically damaging poisonous plant that contains the toxin swainsonine, and a new herbicide, aminopyralid + 2,4-D, may be a better option because it is effective at lower rates, has a shorter average half-life, and has less potential for off-target movement.
Cadillo (Urena lobata) control with POST herbicides
TLDR
Results from these studies suggest that cadillo is susceptible to many of the common POST herbicides utilized in pastures and natural areas in Florida.
Conventional and Organic Options for the Control of Woolly Distaff Thistle (Carthamus lanatus)
TLDR
Control options for both conventional and organic ranching practices where woolly distaff thistle is a problem are provided, including an organic herbicide (mixture of capric and caprylic acids).
Forage Legume Establishment under Exposure to Progressive Declines in Aminocyclopyrachlor and Aminopyralid in Temperate Pastures
TLDR
It is suggested that at least three half-lives of degradation must occur, and likely four or more, before these legumes can re-establish at densities acceptable for pasture production, as well as the role of vegetation competition on legume establishment.
Preemergent Control of Medusahead on California Annual Rangelands With Aminopyralid
TLDR
Aminopyralid has potential utility for suppressing medusahead, particularly in sites also infested with invasive members of the Asteraceae, however, the most effective rate (245 g · ha−1 ae) is registered for use only as a spot application.
Control of Yellow Starthistle (Centaurea solstitialis) and Coast Fiddleneck (Amsinckia menziesii) with Aminopyralid
TLDR
Results show that aminopyralid is a valuable tool for land managers and can play an important role in integrated management strategies for yellow starthistle and coast fiddleneck, and that late-season application resulted in increased annual forage grass production the following year.
Does a Diflufenzopyr Plus Dicamba Premix Synergize Russian Knapweed (Acroptilon repens) Control with Auxinic Herbicides?
TLDR
It is indicated that diflufenzopyr + dicamba does not generally improve Russian knapweed control at 12 or 24 MAT with either standard or reduced rates of typical fall, auxinic herbicide treatments.

Combining Mowing and Fall-Applied Herbicides to Control Canada Thistle (Cirsium arvense)1
TLDR
Inconsistent results prohibit concluding that mowing before spraying will consistently improve Canada thistle control, and such a treatment combination should not be commonly recommended.
Effect of perennial grasses on Canada thistle (Cirsium arvense) control
TLDR
Perennial grass density following seeding followed the same trend, indicating that preplant rototilling improved perennial grass establishment, and competitive grasses were as effective as yearly applications of clopyralid for controlling Canada thistle.
Using the rosette technique for Canada thistle (Cirsium arvense) control in row crops.
TLDR
Glyphosate and clopyralid plus 2,4-D were the most consistent postharvest herbicide treatments for Canada thistle control 8 MAFT in corn and soybean.
Allelopathic activity of Canada thistle (Cirsium arvense) in Colorado.
TLDR
Comparisons between ethanolic extractions and soil incorporation of plant residues with presumably non-allelopathic plants revealed that cucumber and barley extracts reduced redroot pigweed radicle growth whereas barley and green foxtail extracts increased greenfoxtail radicles growth.
Diflufenzopyr Influences Leafy Spurge (Euphorbia esula) and Canada Thistle (Cirsium arvense) Control by Herbicides1
TLDR
Overall, the increase in weed control from the addition of diflufenzopyr was much more pronounced with leafy spurge than with Canada thistle.
Seasonal Changes in Carbohydrates in the Root of Canada thistle (Cirsium arvense) and the Disruption of these Changes by Herbicides1
TLDR
Experiments were conducted to determine whether there was a correlation between herbicide efficacy, time of herbicide application, and the resulting herbicide effect on root carbohydrate and Canada thistle control and showed changes in sucrose, 1-kestose and 1-nystose were shown to be closely associated with changes in soil temperature.
THE BIOLOGY OF CANADIAN WEEDS.: 13. Cirsium arvense (L.) Scop.
This contribution on Cirsium arvense (L.) Scop., Canada thistle (Compositae) is part of a series which presents biological information on plants that are weedy in Canada. Canada thistle is a serious
Using noxious weed lists to prioritize targets for developing weed management strategies
TLDR
A database of noxious weed lists obtained from the 48 continental states and six bordering provinces is compiled, finding that biological control programs have targeted many of the top dicotyledonous weeds of national concern, but none of the weedy grasses and sedges.
AN APPROACH TO ESTIMATING YIELD LOSS OF BARLEY DUE TO CANADA THISTLE
TLDR
Experiments were conducted to determine if a relationship exists between yield loss of barley and various indicators of Canada thistle density and the results probably provides a more accurate estimate of barley yield loss at low levels of CanadaThistle infestation.
