Tolerance trials were carried out under greenhouse conditions to determine the tolerance of cilantroto selected postemergence herbicides. Herbicides used were paraquat (1.68 Kg active ingredient/Ha), MSMA (2.24 Kg ai/Ha), 2,4-D (4.26 Kg ai/Ha), bromoxynil (0.28 Kg ai/Ha), atrazine (2.24 Kg ai/Ha), cyanazine (1.12 Kg ai/Ha), metribuzin (0.25 Kg ai/Ha) dimethenamid (1.12 Kg ai/Ha), endothal (0.56 Kg ai/Ha), linuron (0.75 Kg ai/Ha), imazameth (0.067 Kg ai/Ha), imazethapyr (0.028 Kg ai/Ha), acifluorfen (0.28 Kg ai/Ha), lactofen (0.12 Kg ai/Ha), oxyfluorfen (0.03 Kg ai/Ha), and bentazon (1.12 Kg ai/Ha) as well as the untreated control. Herbicides were sprayed when plants reached the two-true leaf stage (approximately 20 days after emergence). No adjuvant was used in herbicide preparations. Linuron, bentazon, oxyfluorfen, acifluorfen, imazethapyr and metribuzin seemed to be have some potential for weed control in cilantro. Other herbicides caused severe phytotoxicity on cilantro leaves.
