Starane Ultra applied as a banded spray along ‘Draper’ blueberries established in a Downer loamy sand 6 years prior to trial establishment. Starane Ultra was applied twice per year, 30 to 45 days apart, at 11.2 or 22.4 fl oz/a (0.245 or 0.49 lb ai/a). Both rates controlled common grounsel significantly better than the glufosinate standard 14 and 28 days after first application (DAA). Fluroxypyr also provided significantly greater common purslane control at 7, 14 and 28 after the second application (DAB). Injury to new canes was similar or lower than glufosinate, regardless of fluroxypyr rate or evaluation timing. Little to no foliar injury occurred with fluroxypyr (3% or less). Berry yield, weight per berry and % commercial yield was not different between glufosinate and fluroxypyr treatments.
