Everything Old is New Again: Managing Sedges in Rice

Presented by: Dr. Thomas (Tommy) Butts, Extension Weed Scientist, University of Arkansas, System Division of Agriculture
Multiple sedge weed species, including yellow nutsedge, rice flatsedge, and most recently, white margin sedge, have become increasingly troublesome in Arkansas rice acres. The correct identification of the sedge species in the field is a necessity to correctly select an effective herbicide. Additionally, getting the most out of our herbicides requires optimizing the application process. This talk will discuss the identification of common problematic sedge weeds, explore white margin sedge and best management efforts for this species, and identify aerial application methods that can improve efficiency and control.

The Balancing Act of Managing Grasses and Sedges in Rice

Presented by: Austin Miller, Crop Consultant: Nutrien Ag Solutions
The theme of weed control in rice in recent years has become a mandatory two-way approach. It comes down to a decision of which is your more problematic weed at the time, a series of grass species or sedges. After attacking whichever weed is the greater of the two evils, it is important to be ready for a quick post flood application to clean up the other. This talk will discuss the importance of both pre and post flood scouting of these weeds. Additionally, it will consider different control options for white margin sedge, a relatively new problem weed which has become increasingly widespread and troublesome in my area, and how these control options can play into the herbicide program that is already in place.
