- Abstract:
-
A 2-year field study was conducted to determine the effect of row spacing, plant architecture, and postemergence sequential herbicide treatments on season-long weed control in dry bean under sprinkler irrigation. Two row spacings, narrow row (15 and 19 cm) and wide row (56 cm), were compared along with two pinto bean varieties ‘Sequoia’ (Type II growth habit) and ‘Othello’ (Type III growth habit), and six weed control treatments. Weed control in PRE applications alone was unsatisfactory. Hand-weeded and POST sequential application averaged 91% control. Weed interference was reduced in narrow rows combined with POST sequential applications or in wide rows combined with POST sequential applications and cultivation. Narrow rows generally yielded higher than wide rows. However, more weeds were found in narrow rows versus wide rows likely due to cultivation. All treatments yielded higher than the weedy control. PRE only applications yielded significantly lower than POST sequential herbicide applications.
