Weed control is economically important for production of rice, a major crop inArkansas. These findings summarize efforts of the team of Arkansas scientists workingon weed control strategies for rice during 1997. Various technologies were evaluated infield studies at five locations involving the major weed problems and rice productionsystems used in the state. Results from these studies will add to the arsenal of weedcontrol options for producers. Highlights include synergists and safeners for herbicidesto aid in control of propanil-resistant barnyardgrass; herbicides and flooding techniquesfor control of red rice and other weeds; and the use of transgenic rice cultivars for broad-spectrum weed control. The preliminary results reported here generally warrant furthertesting for more advanced findings and for the labeling of new technologies, and finallyare the basis for updating safe, effective, and economical recommendations to Arkansasrice producers.

INTRODUCTION
Herbicidal weed control is economically important for production of rice. Fieldexperiments are conducted annually in Arkansas to evaluate the activity of de-velopmental and commercial herbicides for selective control of weeds in rice.
These experiments serve both industry and Arkansas agriculture by providing informa-tion on the selectivity of herbicides still in the developmental stage and by comparing theactivity of these new herbicides with that of recommended herbicides.
The research reported herein is a compilation of data from experiments conducted byfour of the state’s agronomic researchers responsible for weed control in rice. Ron Talbert,located at the Arkansas Agricultural Research and Extension Center, Fayetteville, con-ducts research at Fayetteville, at the Rice Research and Extension Center, Stuttgart, andat the Lonoke location of the University of Arkansas at Pine Bluff. David Gealy islocated at the National Rice Germplasm Evaluation and Enhancement Center at Stuttgart.Ford Baldwin’s rice research is located primarily at the Lonoke location of the Universityof Arkansas at Pine Bluff. Eric Webster, while he was located at the Southeast Researchand Extension Center at Monticello, conducted rice research at the Southeast BranchExperiment Station at Rohwer.
Common names of the herbicides presented in data tables are referenced to tradenames and sponsoring companies in Appendix Table 1. The scientific names of the plantsevaluated and their associated Bayer codes are listed in Appendix Table 2. Climatologicaldata for 1997 are presented in Appendix Table 3.

METHODS
Pertinent information specific to each field test precedes each data table. Included isinformation on general field conditions, field maintenance and herbicide application, andgeneral conclusions from the data. All test areas were fertilized as recommended fromsoil tests.
The herbicides used in these studies are designated in the tables by the commonname proposed to or accepted by the Weed Science Society of America or, when com-mon names are unavailable, by code number designation. A trade name is specified forcompounds having more than one trade name or manufacturer. The Stam® formulationwas used where propanil formulation is not designated. Herbicides formulated as pre-packaged mixtures are listed in tables by their component herbicides in parentheses. Allherbicide rates are expressed in pounds of active ingredient (lb/A) on a broadcast basis.Adjuvant rates are expressed as percent volume/volume.
Effects of the herbicide treatments were evaluated by weed control ratings, cropinjury ratings, crop yields, and crop stand counts. Percentages of weed control and cropinjury were visually estimated: 0% represents no effect, and 100% represents completekill. Rice yield is reported as lb/A; 1 bushel = 45 pounds. Data were subjected to analysisof variance, and the LSD (Least Significant Difference) test at the 5% level of signifi-cance was used for separation of means.
