New study evaluated different herbicide programs for Palmer amaranth control in post-harvest wheat stubble

A field study was recently conducted that evaluated the performance of various herbicide programs for Palmer amaranth control in post-harvest wheat stubble. Learn more about the results of this research in this article from Weed Scientist, Dr. Vipan Kumar.

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.

Metabolism-based herbicide resistance in a 6-way resistant Palmer amaranth

A six-way herbicide-resistant Palmer amaranth population was the subject of a study recently published by K-State weed scientists. Results from this study demonstrate that a single resistance mechanism can provide resistance to multiple herbicide groups.

Considerations for weed control following wheat harvest

Post-harvest weed control in wheat stubble is very important to conserve soil moisture and prevent weeds from going to seed and adding to the weed seedbank. Weeds can grow quickly once the wheat canopy is removed.

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.
