Abstract
Field trials were conducted at Scott and Saskatoon, SK from 1994 through 1997 to determine the optimum rate and timing for five post-emergent herbicides used to control wild oat in spring wheat. The herbicides tested were clodinafop-propargyl, fenoxaprop-P, flamprop, imazamethabenz and tralkoxydim. Herbicides were applied at the recommended label rate, 0.67 times or 0.33 times the recommended rate at the 2-, 4- or 6-leaf stages of wild oat. Wild oat infestation was moderate to heavy at Saskatoon and light to
moderate at Scott.
