Abstract: Sugar beets grown for seed in central Oregon is a small, established industry. Weed control in sugar beets is dependent on precise application timings early in weed development for adequate control while minimizing crop damage. This project was designed to evaluate layby herbicide applications to extend weed control during row closure and minimize the need for hand weeding. Outlook at 18 oz/acre plus Nortron at 16 oz/acre provided the best control at 75 percent. There was a broad spectrum of weed species in the plot area, with common lambsquarter, hairy nightshade, redroot pigweed and knotweed included on the herbicide labels that were tested.
