Resistant barnyardgrass, yellow nutsedge studied at University of Arkansas

“We want to understand how to best protect technologies and herbicides within rice and other crops," says Jason Norsworthy, University of Arkansas weed scientist. "Towards that end, we’ve done a lot of modeling work, initially with Palmer amaranth in cotton.”
“Many of the strategies recommended today came out of the initial modeling work we did on glyphosate-resistant Palmer amaranth. For example, the overlaying of residual herbicides and making sure you provide season-long weed control and prevent escapes are a result of our modeling efforts.”
