Abstract

Field experiments were carried out in two successive winter season, 2002 and 2003 at Research Experimental Station of Faculty of Agriculture, Alexandria University in wheat (Triticum aestivum cv. Sakha 8), using two compounds from sulfonylurea herbicides, tribenuron-methyl (Granstar) and (thifensulfuron-methyl + metsulfuron) (Harmony) at 0.5, 0.75 or the recommended field rate either alone or mixed with mineral or vegetable oils. The results revealed that, the tank mix of vegetable oil at (0.5%) with tribenuron-methyl (0.75 fold of field rate) was reduced the cost per feddan up to the quarter of the cost. Also, thifensulfuron-methyl + metsulfuron (Harmony) had the same trend when mixed with 1% mineral oil. At the applied doses, a reduction of costs per feddan ranged from 10 to 15 LE was happened.
