Controlling marestail or pigweeds post-emergence in soybeans is always easier when the weeds are small – less than 2 inches tall is preferable for good control. This article outlines some suggestions for controlling these weeds post-emergence in soybeans.
Controlling marestail in soybeans continues to be a big challenge for Kansas no-till producers. Application timing and weed size are critical factors for successful control of this weed that germinates in the fall or early spring.
Timely herbicide applications are key for post-emergence control of marestail. Management is complicated due to some populations in Kansas with resistance to glyphosate and ALS-inhibiting herbicides. However, there are some options for control of large marestail.
With row crop harvest well underway, it is time to start planning fall herbicide applications. Herbicide applications in late October through November can improve control of difficult winter annual weeds.

Controlling marestail in soybeans continues to be a big challenge for Kansas no-till producers. Learn about early spring, pre-plant, and post-emergence options for treatment in this article from Extension Weed Science Specialist, Dr. Sarah Lancaster.

Marestail or "horseweed" is a challenging weed to manage in no-till or minimum till systems. Fall-emerged marestail can be difficult to control if allowed to grow until planting in the following spring. Different control options are available for use in the fall while plants are still small.

Application timing and weed size are critical factors for successful control of this weed that germinates in the fall or early spring.

Controlling marestail in soybeans continues to be a big challenge for Kansas no-till producers. Application timing and weed size are critical factors for successful control of this weed that germinates in the fall or early spring. Marestail that does survive over winter is often robust and can be difficult to control with herbicides, especially later in the spring.
Marestail, or horseweed, is a challenging weed to manage in no-till or minimum-till systems. Acceptable control of fall-emerged marestail with herbicide applications at planting will be unlikely because the marestail are generally too large, but control can be achieved with both fall and early spring herbicide applications. Other control options include tillage and cover crops.

Marestail, or horseweed, is a challenging weed to manage in no-till or minimum-till cropping systems. Acceptable control of fall-emerged marestail with herbicide applications at planting will be unlikely because the marestail is generally too large. Control can be achieved with both fall and early spring herbicide applications. Other control options include tillage and cover crops.
