Fleabane Fleabane is a A short-lived herbaceous plant developing a basal rosette of leaves at first. Previous research with several preplant herbicides resulted in variable control of GR Canada fleabane in soybean. At the top of this list, Sikkema says, is use of a preplant burndown. The widespread incidence of herbicide-resistant Canada fleabane highlights the importance of developing integrated weed management strategies. The plant is very adaptable to differing conditions and can vary dramatically in height, from only a few centimetres in poor soils to as much as 3 metres tall in rich soils. In 2010, the first eight GR Canada fleabane populations were identified in Essex County. But for producers with multiple resistant Canada fleabane, this herbicide will not be effective. Its upright branched stems are densely hairy and usually grow up to 1 m tall. Canada fleabane, also called Horseweed, is native to North America and has become a weed in South America, Europe, Asia, and Africa. However, across the province, there appears to be a more immediate threat for the 2020 season from glyphosate-resistant Canada fleabane. A study led by another graduate student, Christopher Budd, in 2014 and 2015, built on that research and found that the most efficacious tank mix for the control of glyphosate-resistant Canada fleabane was glyphosate plus saflufenacil plus metribuzin applied pre-plant in Ontario. Glyphosate-resistant weeds such as Canada fleabane have become increasingly difficult to manage across Ontario. per hectare) does not always provide consistent control of the weed. https://www.topcropmanager.com/top-crop-summit-2021-sweepstakes-winners-announced/, Our second #TCSummit Sweepstakes draw is tomorrow! Description. Learn more about fleabane control in this article so you can eradicate it should the need arise. Control of Glyphosate Resistant Canada Fleabane (Conyza canadensis (L.) Cronquist) with 2,4-D Choline/Glyphosate DMA in Corn (Zea mays L.)By Laura Ruth-Agnes Ford A Thesis Presented to Canada fleabane is the second documented glyphosate-resistant (GR) weed species in Ontario, Canada. A study led by Sikkema’s graduate student, Holly Byker in 2011 and 2012, found that burndown applications of Roundup plus saflufenacil (Eragon) provided the most consistent control of Canada fleabane, but even this tank mix did not provide acceptable control in all situations. Figure 8: Flowers of the Canada fleabane weed. "Control of Canada Fleabane (Conyza canadensis) with glyphosate DMA/2,4-D choline applications in corn (Zea mays). It thrives under cool, damp conditions and little soil disturbance. Glyphosate-resistant Canada fleabane is very difficult to control in soybean: studies have shown it emerges 11 out of 12 months of the year in southern Ontario – skipping only January. per hectare at eight weeks after application.

Common names include horseweed, Canadian horseweed, Canadian fleabane, coltstail, marestail, and butterweed.It was the first weed to have developed glyphosate resistance, reported in 2001 from Delaware. Notably, no Canada fleabane grew where cereal rye was planted in the fall (see Figure 4 below), regardless of herbicide or tillage treatment.
