The study was conducted to evaluate the residue effects of four sulfonylurea herbicides of corn include Titus (rimsulfuron), Samson (nicosulfuron), Equip (foramsulfuron) and Ultima (nicosulfuron+rimsulfuron) and two herbicide dosages and application time of Lumax (mesotrion+ terbuthylazin+s.metalachlor, Pre-emergence and Post-enmergence) on wheat at the next year. The experiment was done at Shavoor Station in Ahvaz in a randomized complete block design. After harvesting of corn plants, the wheat seeds were sown in the same place. Phtotoxicity syndromes, dry weight of wheat seedlings, plant height and yield were measureed at proper time. The results showed that. all Lumax treatments(as4 and 4.5 l/ha pre and post emergence) have significant reduction on yield, yield components and plant height in Khuzestan. Other hebicides of experiment No evidence were obtainne of herbicide residue adverse effects on wheat.
