New Obstacles In South Louisiana Rice Production

Presented by: Dr. L. Connor Webster, Assistant Professor of Weed Science, LSU AgCenter

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.


Ineffectiveness Of Provisio Herbicide In Outcrossed Red Rice

Presented by: Barrett Courville, Louisiana Consultant

Despite all the efforts to retain control of noxious weeds in rice, Mother Nature often finds a way to get around them. Among the problems noted the past year in rice production in Southwest Louisiana, has been the resistance of outcross red rice to Provisio herbicide. Courville will discuss the problems he has seen in the recent Provisio rice crop. He will also present information on rice consulting in Southwest Louisiana. He holds a master’s degree from Louisiana State and a bachelor’s from McNeese State University. He spent 33 years as an LSU agricultural agent, 4 years as a consultant for Helena and 4 years with his own company, BC Rice Consulting.
