Center for Plant Health Science and Technology; California Department of Food and Agriculture. Noxious weeds must be controlled, meaning their growth or spread needs to be prevented. The plant develops an extensive root system that spreads both vertically and horizontally. Canada thistle invades natural areas such as prairies, savannas, glades and dunes if some degree of disturbance already exists. Rust alone does not usually reduce stands unless combined with stem weevil. The stems above the galls are usually non-productive with abnormal seed heads. The plant is also able to regenerate itself from very small pieces. Then leave pasture to rest for about 8 weeks (depending on growing conditions) so grass stays competitive. MowingFrequent mowing during the growing season can substantially reduce Canada Thistle populations in forage stands, and 3 years of mowing treatments severely reduced Canada Thistle in most studies. Dispersal Dispersal by seed is important in establishment of Canada thistle into new areas, but once established vegetative propagation is the main method of spread. Effect of Canada thistle (Cirsium arvense) residue on growth of some crops. Vertical roots commonly reach depths of 2 – 3 meters and have been found at depths of up to 6.75 m while horizontal roots can spread out up to 6 m (in one season) from the mother plant. Minimizing soils disturbances and promptly re-vegetating disturbed areas with competitive plants will also prevent establishment of Canada thistle. Canada thistle plants are dioecious; male and female flowers are borne on separate plants. Seeding smooth brome (Bromus inermis Leyss.) Australian Government. Impact on the Canada thistle—the insect does not kill the plant, however, it reduces the plant’s ability to compete and resist pathogens. Dispersal by seed is important in establishment of Canada thistle into new areas, but once established vegetative propagation is the main method of spread. University of Nebraska - Lincoln. Where it Grows (Habitat & Ecology): Canada thistle is found in annual and perennial crops, rangeland, riparian areas, non-crop areas and industrial sites. A habitat conservation area in Regina's Wascana Centre also used goats to control populations of invasive plants (Canada thistle and caragana), which reduced the use of herbicides. - a systemic rust infection that can occur in most regions of Alberta as long as moisture is not limited.
