Marestail in soybeans: Strategies for the best control

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.

Get control of fall-emerged marestail before next 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.
