Canada Thistle Management Systems for Sustainable and Organic Farms
Additionally, field studies were conducted on populations of USDA landrace and commercial sorghum accessions to evaluate morphological traits, regrowth potential, and suitability for cover cropping and biofuel applications. Canonical variates in Canonical Discriminant Analysis (CDA) indicated that …

Multiple stresses by insect and plant-competition on growth and productivity of Canada thistle
Canada thistle is an aggressive perennial weed throughout temperate areas for both the northern and southern hemisphere. As various single tactics have shown limited success in controlling this weed, I believe that a combination of different stress factors is necessary for effective sustainable …

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 …

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.)
… an average of 27.4 ± 1.7 days when reared on Canada thistle and 28.5 ± 2.1 days on an alternate host, musk thistle. Mortality due to incomplete development totaled 52.5% for immatures reared on Canada thistle and 79.0% for immatures reared on musk thistle. Mean survival from egg to adult of …

Weed management in conventional, no-till, and transgenic corn with mesotrione combinations and other herbicides
… weeds horsenettle (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 …
