Sethoxydim is a postemergent herbicide for control of grass weeds in a wide variety of horticultural crops.[1][2][3]

Sethoxydim is sold under brand names including Poast,[1][4] Torpedo, Ultima, Vantage, Conclude, and Rezult. It is manufactured by BASF, TopPro, and Monterey Lawn and Garden.[4]

Mode of Action

Sethoxydim is a substituted 1,3-cyclohexanedione[5] DIM herbicide, a type of Acetyl-CoA carboxylase inhibitor (ACCase herbicide), WSSA/HRAC Group 1 (formerly in HRAC A).[6][2]

Resistance

Resistant crops

Maize (corn) resistant to ACCase inhibitors has been produced by selection under sethoxydim application.[5]
