Kansas weed survey - Reminder to participate before August 31

Please consider completing a short survey on herbicide resistant weed control. The survey will close at the end of August. Information collected will help develop innovative, cost-effective and integrated weed management practices for Kansas farmers.

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.

Imazamox-resistant shattercane populations identified from sorghum fields in northwest Kansas

Shattercane is a summer annual grass weed species commonly present in grain sorghum producing regions, including Kansas. Current research studies in western KS have identified 3 populations of shattercane with low-to-moderate resistance to imazamox.

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.
