Abstract
Field studies were conducted to evaluate POST herbicides with adjuvants for the control of three-cornered jack in winter wheat. The herbicides evaluated were fluroxypyr 9.7% w/w + MCPA 38.8% w/w (formulated mixture [450 g ai ha −1 ]), carfentrazone-ethyl (20 g ai ha −1 ), bromoxynil 26.8% w/w + MCPA 40.0% w/w (formulated mixture [450 g ai ha −1 ]), thifensulfuron-methyl (75 g ai ha −1 ), and tribenuron-methyl (75 g ai ha −1 ), applied alone or tank mixed with the adjuvants alkyl ether sulfate sodium salt (625 mL ha −1 ) or fatty alcohol ethoxylate (375 mL ha −1 ). The addition of adjuvants to carfentrazone-ethyl resulted in > 94% control of three-cornered jack. Both adjuvants enhanced the efficacy of all herbicides for control of three-cornered jack, except thifensulfuron-methyl. However, a maximum increase in phytotoxicity on three-cornered jack was achieved with the addition of either adjuvant to tribenuron-methyl compared with herbicides used alone. Bromoxynil + MCPA and carfentrazone-ethyl gave maximum wheat yield and yield components.
