Abstract
Selected sweet potato clones were evaluated in greenhouse and field trials to identify clones with superior tolerance to bentazon. ‘Julian’ and NC 1519 were the most tolerant in the greenhouse. ‘Sweet Red’ exhibited foliar injury in the field, but yields were not reduced. The clone 79-BM-17 was equally tolerant in the field as Sweet Red, but in the greenhouse exhibited only intermediate tolerance. ‘Jewel,’ a widely grown commercial cultivar, was sensitive to bentazon in both the greenhouse and field. When averaged over all clones sweet potato injury increased as bentazon rate was increased from 1.1 to 2.2 kg ai ha-1, but it decreased as the season progressed. Bentazon did not reduce marketable yields at Clayton, NC. Bentazon as a split or late application at the 2.2 kg ha-1rate, reduced yields at Clinton, NC. Percent culls among bentazon treatments did not differ at either location.
