Abstract

In greenhouse studies, tralkoxydim applied POST at 100 to 300 g ai/ha during the three-to four-leaf stage of development were differentially toxic to three Hordeum species. Tralkoxydim severely injured wall barley by cessation of growth and death of the whole plant. Hordeum spontaneum, barley, and wheat were less affected by the herbicide in declining order, respectively. However, 4 wk after treatment, full recovery was observed in barley and wheat, but not in H. spontaneum, as reflected in the shoot fresh weight. Tralkoxydim could be considered as a selective herbicide in wheat and barley fields for the control of wall barley.
