Palmer amaranth pigweed is typically not a problem for rice producers since the floodwaters keep it in check, and producers do not need herbicides to control it. But rice farmers who have switched to furrow irrigated row rice are finding that herbicides are essential to control pigweed. And that comes with the potential for rice injury.
At the recent National Conservation Systems Cotton and Rice Conference in Memphis, Ryan Sullivan discussed the challenge he and his father, Mike, have faced as they try to control weeds without injuring rice.
