2023 Abstract - NEW OBSTACLES IN SOUTH LOUISIANA RICE PRODUCTION: Over the past few growing seasons, the amount of inquiries concerning the control of Fimbristylis littoralis has grown exponentially. Fimbristylis is often times misidentified as rice flatsedge (Cyperus iria L.), which leaves many growers in a dilemma later in the growing season. Both Fimbristylis and rice flatsedge belong to the cyperaceae (sedge) family; however, chemical control of these two weeds differ greatly. An on-farm study was conducted in 2022 in Abbeville, Louisiana to determine the most effective control measures for Fimbristylis.
