• The experiment was carried out in a greenhouse to investigate copper (Cu) and molybdenum (Mo) interaction in Elytrigia elongata. Three rates of Mo (0,0.5, and 1 mg kg -1 ) and three rates of Cu (0,5, and 10 mg kg -1 ) were applied to all combinations to Elytrigia elongata grown on a halomorphic soil. The plants were cut three times, the first one 60 days after seeding, and the other two 120 and 180 days later, respectively. The results indicated that an antagonistic interaction between Cu and Mo existed in the first and in the third cut, but there was no evidence of it in the second cut. The antagonism between the two micronutrients studied was evident in the aerial part of the plant beyond a Mo concentration of 2.5±0.5 mg kg -1 , proposed as "threshold".
