Recent mild temperatures and the mild winter are setting the stage for rapid development of marestail/horseweed (Conyza canadensis) this spring. Marestail was particularly troublesome last year in soybeans. Marestail can germinate in both the fall and the spring. It
Marestail, also known as horseweed or Canada fleabane, is a winter or summer annual weed in Nebraska. Historically, marestail was found in waste area, field edges, along roadsides, and railway tracks; however, no-till crop production systems over the last 20
Marestail is a problematic winter annual weed that is often resistant to glyphosate. But control isn’t as hard as you think and just takes a little planning.
Louisiana growers across the state must deal with glyphosate resistant palmer pigweed, waterhemp, Italian ryegrass, and Johnsongrass. Although not officially documented, resistant horseweed is also a concern for northern parishes.
Horseweed, commonly called marestail, is the most troublesome weed at burndown for most farmers in north Alabama but ryegrass has become public enemy number two.
Horseweed (marestail, Conyza canadensis L.) is a unique weed species that can emerge in both fall and spring. In Nebraska, unlike the eastern Corn Belt, horseweed populations predominantly emerge in fall as a winter annual. Horseweed is native to North
