Abstract

Field experiments were conducted in 1992 and 1993 in southern Manitoba to investigate the tolerance of buckwheat, canola, field pea, lentil, and sunflower to simulated drift of 2:1 mixtures of thifensulfuron:tribenuron. Thifensulfuron:tribenuron at 0.23 to 3.6 g ai/ha was highly phytotoxic to all crops examined. Leaf area index 2 and 4 wk after treatment, seed yield, and seed weight were reduced for all crops at the rates examined. Predicted yield losses at 0.23 g/ha, averaged over two years, were 16% for sunflower, 20% for buckwheat, 22% for canola, 26% for lentil, and 37% for field pea. For each of the five crops, there was a strong linear relationship between percentage visual injury 2 wk after exposure and final yield. Simulated thifensulfuron:tribenuron drift reduced seed oil content of canola and sunflower. In one year, canola, field pea and lentil seed germination was reduced following exposure to simulated drift.
