Abstract

Studies were conducted to determine the response of ‘Jewel’ sweetpotato in propagation beds to DCPA and napropamide. Napropamide at 2.2 and 4.4 kg ha–1 caused slight injury, and reduced plant number and weight when compared with the untreated control. Napropamide at 1.1 kg ha–1 combined with chloramben at 3.3 kg ha–1 was not injurious; plant production was equal to the untreated control, diphenamid at 4.4 kg ha–1, and chloramben at 3.3 kg ha–1. DCPA at 8.3 and 10.0 kg ha–1 caused unacceptable injury and reduced plant number and weight.
