Abstract

Field experiments were conducted in Greece during 1997, 1998, and 1999 to study the efficacy of various preemergence and postemergence herbicides against red rice. Tolerance of rice seeded 15 and 6 d after preemergence and postemergence herbicide application was also examined. Control of red rice with alachlor, dimethenamid, metolachlor, or acetochlor applied preemergence was 92, 84, 92, and 92%, respectively. The corresponding control with postemergence applications of paraquat, glyphosate, glufosinate, or quizalofop-ethyl to emerged red rice seedlings was 92, 89, 81, and 100%, respectively. None of the herbicides had any phytotoxic effect on rice cultivars planted after the herbicide application, and grain yield produced in treated plots was higher than that in untreated plots. These results clearly showed that red rice can be effectively controlled by applying the previously mentioned preemergence or postemergence herbicides and that rice could be safely seeded 15 and 6 d after treatment, respectively.
