Abstract

The effectiveness of postemergence applications of triallate [S-(2,3,3-trichloroallyl)diisopropylthiocarbamate] for wild oat (Avena fatua L.) control in spring wheat (Triticum aestivum L. ‘Waldron’) was evaluated in the field and greenhouse. The stage of the wild oat plants at the time of treatment did not appear to influence wild oat control with postemergence applications of triallate in the field; however, in the greenhouse, wild oat plants became more resistant with increased maturation. Granular triallate was more effective than the emulsifiable concentrate for postemergence wild oat control. Fair season-long postemergence wild oat control was obtained with the granular formulation of triallate at rates of 2.24 kg/ha or greater. However, some wheat injury was observed in the field with the 2.80 and 3.36 kg/ha rates of granular triallate. Moisture and temperature influenced postemergence wild oat control with triallate.
