Transplanted Pepper (Capsicum annuum) Tolerance to Selected Herbicides and Method of Application

Abstract

ABSTRACT Field studies were conducted to evaluate the tolerance of the pepper (Capsicum annuum L.) cultivars ‘Bell Captain’ and ‘Surefire Banana’ to the herbicides bentazon, fomesafen, napropamide, oxy-fluorfen, pyridate, and sulfentrazone. Both peppers exhibited good tolerance, stand establishment, and fruit number and total yield with fomesafen at 0.28 and 0.42 kg/ha applied pretransplant (PRE-T) and posttransplant (POS-T) on day of planting, napropamide at 2.24 kg/ha PRE-T, oxyfluorfen at 0.28 and 0.56 kg/ha applied PRE-T, and bentazon at 0.56 and 0.84 kg/ha applied two wk after transplanting (EPOST). Oxyfluorfen at 1.12 kg/ha PRE-T and sulfentrazone at 0.42 kg/ha applied PRE-T and POS-T caused severe injury, stand reduction, and reduction in number of fruit and yield for these cultivars. Pyridate at 1.26 kg/ha EPOST injured plants but numbers of fruit and yield were not consistent across years for this treatment.
