Optimization of application efficacy for POST herbicides with adjuvants on three-cornered jack (Emex australis Steinheil) in wheat
Weed Technology 27 (3), 437-444
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.
