Field experiments were conducted to assess the efficacy of herbicides applied pre– (pre–forking) and post–emergence (after harvest) in spring and autumn during 2000–2002 in saffron fields of Mashhad and Gonabad located in north–eastern and eastern parts of Iran, respectively. In spring trials, ioxynil (750 g a.i. ha–1) and tribenoronmethyl (18.75 g a.i. ha–1) when sprayed at 6–8 leafy stage of weeds after saffron harvest were more potent than metribuzin. In autumn trials, weed control by ethalfloralin (1320 g a.i. ha–1) and trifloralin (960 g a.i. ha–1) when applied pre–emergence and before saffron flowering was promising but caused also some damages on saffron, leading to yield loss. Application of metribuzin (560 g a.i. ha–1) whether in spring or autumn, controlled weeds without any saffron injury. Tribenuron–methyl and metribuzin were the best treatments for weed control in saffron fields of Mashhad and Gonabad, respectively.<\div>
