DISTRIBUTION In BC, tansy ragwort is found in the central Fraser Valley, central to southern Vancouver Island, the Gulf Islands, and the east side of the Okanagan Valley between Kelowna and Penticton. [...] The basal leaves are stalked and range from 4 to 20 centimetres long and 2 to 6 centimetres wide. [...] Boundaries can be easily monitored and controlled to prevent the spread of tansy ragwort onto adjacent lands. [...] Mechanical Control: ▶ Mechanical control is only effective when the entire root system can be removed or when the area is frequently cultivated (tilled) to prevent new seedlings and sprouts from growing. [...] Chemical Control: Before selecting a herbicide, it is essential to evaluate the site-specific characteristics and consider the overall goals and objectives for the area as these will guide the choice of herbicide and application strategy.
