The efficacy of flamprop methyl and its active isomer (WL43423) on wild oats (Avena fatua L.) in field corn (Zea mays L.) was studied in field plots at Morden, Manitoba from 1983 to 1985. The herbicides were applied at recommended rates at the two-leaf, four-leaf and six-leaf stages of field corn. Spraying at the four-leaf stage consistently provided maximum wild oat control with acceptable field corn tolerance. When 2,4-D amine was applied at the same time as flamprop methyl, reduced wild oat control and field corn tolerance was observed.Key words: Oat (wild), Avena fatua, corn (field), Zea mays, flamprop methyl, WL43423
