Field experiments were done during winter seasons of 1988–89 and 1989–90 at Haryana Agricultural University, Hisar, India. Wild oat (Avena ludoviciana)was effectively controlled at 20 and 30 d.a.s. with 0.25 to 0.35 kg/ha tralkoxydim. The average reduction of wild oat population by 0.30 and 0.35 kg/ha tralkoxydim was 73.5 and 85.4%. Significantly better efficacy of tralkoxydim was obtained with spraying than broadcasting it with urea or sand at both the stages of application. An increase in the concentration of tralkoxydim enhanced control of wild oat. On an average of application times and methods, tralkoxydim at 0.25 kg/ha gave poor wheat yields. Tralkoxydim application at 30 d.a.s. produced significantly better crop yields than its earlier application.
