K-State has confirmed the occurrence of dicamba and 2,4-D resistance in a Palmer amaranth population collected from a long-term conservation tillage study at the K-State Agronomy Ashland Bottoms Experiment Field in southern Riley County. This is the first confirmed case of resistance to dicamba and 2,4-D in Palmer amaranth, further magnifying the challenge to manage this weed in conservation tillage systems. |

The decision to pursue state-specific Special Local Needs labels was made in response to the record number of misuse complaints Illinois Department of Agriculture (IDOA) received during the past two years. “Illinois Farm Bureau supports the IDOA in their administration of pesticide rules that they deem necessary to limit adverse effects on the environment,” said Richard Guebert, Jr., Illinois Farm Bureau President.

In U.S. currency, the new model is priced at about $60,000. Additional charges apply to install the unit on a farmer’s combine, but the project can be done on the farm. Based on earlier pricing for the original horizontal mill, that’s about $25,000 less.

Several reports of new weed resistance came to light recently. First, Illinois reported 2 populations of waterhemp resistant to metolachlor and other Group 15 herbicides. This was followed by reports of metolachlor and then 2,4-D resistance in Palmer amaranth by Arkansas and Kansas, respectively. The Kansas Palmer amaranth population is also resistant to dicamba. Quite likely, these cases are due to the weeds’ ability to rapidly degrade the herbicide. This metabolism-based resistance poses a bigger threat than target site-based resistance.

Not particularly satisfied with how a stock roller-crimper terminated a cover crop, a team at the University of Nebraska reworked the concept.
