To investigate the possibility of tank-mix application of two herbicides; Cruz (nicosulfuron 4% SC) and Bromicide MA (bromoxinil+ mcpa 40 % EC) for control of weeds in corn an experiment was carried out in Jiroft and Kahnoj Agricultural Research center during 2009. The experiment was conducted in a factorial experiment based on randomized complete block design with four replications. The first factor was Bromicide MA (bromoxynil + mcpa) at 0, 0.5, 1.0 and 1.5 liters per hectare and the second factor was Cruz (nicosulfuron) with 0, 1.0, 1.5 and 2.0 liters per hectare. Results indicated that the tank mixture of these two mentioned herbicides had a significant effect on the density and dry weight of Digera muricata, Portulaca oleracea, Echinochola colonum, and Cynodon dactylon. Not only did they control the mentioned weeds more effectively but also increased corn yield. The most efficient treatment was mixture of Bromicide MA (bromoxynil+mcpa) one liter per hectare plus Cruz (nicosulfuron) at 1.5 liters per hectare which increased corn grain yield by 23%.
