Interpretive Summary:

Technical Abstract: The weeds, green and yellow foxtail (Setaria viridis and S. glauca), consistently grow and flower prolifically after wheat harvest in the northern Great Plains, potentially replenishing or increasing the soil seedbank of these species. Harvested wheat fields often are tilled or sprayed to prevent seed shed of these weeds. However, the necessity and optimum timing of these operations are unknown, but were the source of man inquiries at grower meetings in recent years. We found that to minimize seed production of foxtails, fields had to be tilled (disked) or sprayed (glyphosate) within 14 days of harvest.
