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.
