Abstract

Field studies were conducted to determine the selectivity and efficacy of pronamide alone or with sethoxydim and trifluralin, in Belgian endive. Pronamide at 1.68 with sethoxydim or alone or at 2.24 kg ai ha−1 controlled weeds better than trifluralin at 0.6 or 1.0 kg ai ha−1 in the field. Pronamide at 2.24 kg ha−1 was the best at controlling grass and broadleaf weeds season-long. In nutrient culture studies, Belgian endive roots were injured at 5 mg L−1 of pronamide, whereas redroot pigweed and green foxtail were inhibited at 0.5 and 0.1 mg L−1, respectively. Shoot weights showed similar differences but were less sensitive than roots.
