Evaluation of Bioherbicidal Properties of Pseudomonas syringae pv. tagetis for Control of Canada thistle (Cirsium arvense)
Canada thistle (Cirsium arvense, family Asteraceae) is a particularly aggressive invasive plant species that is problematic in Canadian agriculture. It can be particularly challenging for organic farmers, as it cannot be eliminated using methods like tillage, due to its ability to regrow using …

The complex foraging strategy of the specialised gallfly Urophora cardui (Diptera: Tephritidae) for host plants (Cirsium arvense, Asteraceae)
… fly Urophora cardui on the creeping thistle, Cirsium arvense, was investigated as an example for the foraging of a specialised herbivorous insect. Males and females of U. cardui use the larval host plant as rendezvous place. The males establish territories on the plant, which they defend …

Canada thistle (Cirsium arvense [L.] Scop.) response to mowing, herbicide, competitive grasses, and soil amendments on wetland, upland, and mesic sites
Canada thistle (Cirsium arvense [L.] Scop.) is one of the most problematic weeds of temperate regions and is found throughout North America, Europe, Africa, and across central Asia. Canada thistle's ability to spread quickly and recover from many control methods makes managing Canada thistle a …

Field biology and mortality factors affecting Cassida rubiginosa Müller (Coleoptera: Chrysomelidae), a biological control agent of Canada thistle (Cirsium arvense (L.) Scop.)
Mean overwintering survival of beetles was 20.5 ± 17.2% and 21.3 ± 3.6% for two consecutive years. Leaf litter was the preferred hibernaculum followed by straw. Successful overwintering was not compatible with water saturated soil. The mean supercooling point of C. rubiginosa in summer was -5.2 ± …

The Effects of Mammalian Herbivores on Successional Grasslands in Central Illinois
… which had highly palatable shoots and seeds. Cirsium arvense, a palatable forb, increased substantially with the removal of deer and the grass Festuca elatior declined. Woody seedlings rarely occurred in the grasslands and none of the mammals affected their abundance.

Multiple stresses by insect and plant-competition on growth and productivity of Canada thistle
… on growth and survival of Canada thistle (<i>Cirsium arvense</i> Scop.). Plant competition was from a cornbination of tall fescue (<i>Festuca arundinaceae</i> Schreb.) and crownvetch (<i>Coronilla varia</i> L). Artificial defoliation was used to determine the influence of level and frequency …

Biodiversity and agro-ecology in field margins
… important weeds Elymus repens Gould, Cirsium arvense L. and Urtica dioica Scop. was significantly higher when cuttings were not removed and in the unsown community. Seed dispersal into the adjacent crop was only of importance one year after installation of the margin strips; seedrain …

Weed management in conventional, no-till, and transgenic corn with mesotrione combinations and other herbicides
… (Solanum carolinense L.) and Canada thistle [Cirsium arvense (L.) Scop.]. Additions of atrazine increased the rate of plant tissue necrosis on these perennial weeds as compared to the slower bleaching symptoms associated with mesotrione applied alone. In general, Canada thistle plants were …

ASSESSING THE PERFORMANCE OF SAMPLING DESIGNS FOR MEASURING ABUNDANCE OF UNDERSTORY PLANTS AFTER FOREST RESTORATION
… efficiently sampled less-common species: for Cirsium arvense, an invasive non-native plant, adaptive sampling required five times fewer replicates than needed for modified Whittaker plots and 20 times less than for Daubenmire or point line intercept transects. My findings suggest that …

Drought Resistance and Resilience of Non-native vs. Native Grasses in the Northern Tallgrass Prairie

Functional diversity and mowing regime of flower strips as tools to support pollinators and to suppress weeds
… summer and autumn. The cover of important weed, Cirsium arvense, was limited by adding forbs to the seed mixture and by mowing in summer or in summer and autumn. At last, by surveying plant-pollinator networks in perennial flower strips and natural hay meadows in the same landscape context, we …
