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%.

To investigate the possibility of tank-mix application of two herbicides; Nicosulfuron+ Rimsulfuron (Ultima 4% SC) and Bromoxinil+MCPA (Bromicide MA 40 % EC) for control of narrow and broadleaf weeds in corn an experiment was carried out in Jiroft Agricultural Research Centers during 2010. The experiment was conducted in a Rrandomized Complete Block design with two-factors and four replications. The first factor was Nicosulfuron+ Rimsulfuron dosage at four levels; 0, 125, 150 and 175 grams per hectare and the second factor was Bromoxynil +MCPA at 0, 0.5, 1.0 and 1.5 liters per hectare. The results showed that the best combination of tank-mix of the above mentioned herbicides, considering weed control efficiency and percent of corn yield augmentation was 0.5 to 1.0 liters per hectare of Bromoxinil+MCPA and 125 to 150 grams per hectare of Nicosulfuron+ Foramsulfuron. These treatments had the best control of weeds of Digera muricata, Portulaca oleracea, Convolvulus arvensis, Physalis alkekengi, Amatanthus.
