Post-emergence marestail control in soybean fields
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.
In-season Palmer amaranth control in grain sorghum
With adequate moisture and high temperatures, Palmer amaranth populations are rapidly growing and causing concern for some sorghum producers in western Kansas. What options to growers have at this point in the growing season? Read more in the article from weed scientist Dr. Vipan Kumar.
Marestail in soybeans: Strategies for the best control
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.

Palmer amaranth control in grain sorghum
Pre-emergence herbicides are critical for successful weed management in grain sorghum, especially for difficult to control species like Palmer amaranth. When pre-emergence control efforts fail, learn the best options for Palmer amaranth in sorghum fields later in the growing season.
