How do you identify a marestail?
Marestail begins as a rosette, and the stem elongates to about 1.5 to 3 feet prior to flowering, although some plants may reach heights of greater than 6 feet (Figure 1). Stems are covered with coarse hairs. Leaves are oblong in shape with margins that range from entire in the rosette to toothed as the stem elongates.
What herbicide will kill marestail in soybeans?
glyphosate
With widespread resistance of marestail to glyphosate and ALS-inhibitor herbicides, growing Liberty Link soybeans in conjunction with applications of burndown and residual herbicides followed by application of POST Liberty herbicide is the most effective system for controlling and/or managing GR marestail.
What herbicide controls marestail?
Control options for marestail in corn include: Acuron or Resicore can be applied early post-emergence when corn is less than 12 inches tall and marestail is less than 4 inches. Other herbicides such as Realm Q or Capreno + atrazine also can be considered. DiFlexx is a formulation of dicamba with CSI safener.
How do you control marestail in soybeans?
Marestail is most easily controlled when in the seedling or rosette stage, and burndown herbicides should be applied prior to stem elongation. Marestail competes with the soybeans throughout the growing season, and reduces crop yield.
How do I identify fleabane?
Identification. Annual fleabane is first visible in early spring as a rosette of light green, succulent leaves. Leaves elongate rapidly and can grow up to 5 inches in length if not mowed frequently. Individual leaves are sessile, lance-shaped with a pointed tip and serrated margins.
