Efficiency of New Herbicide of Sulfosulfuron + Metosulfuron in Weed Control of Wheat

The use of new herbicide is developing in recently years in Lorestan County but efficiency some of these are doubt after 1 to 2 year use. So that assayed the efficiency of the new herbicide Sulfosulfuron Metosulfuron as random complete Block design in four replications in compare custom herbicide before wide use in Aleshtar County. Result showed that Sulfosulfuron Metosulfuron haven’t any effect on grass weed and dry weight of wild oat (Avena fatua L.) Black grass (Alopecurus myosuroides L.) was more than 45 (g/m2) in this treatment and they reached to the product of the seed and while damage percent on this weed was more 98 percent from of the mix of tribenuron Clodinofop proparjyle. The dry weights of broadleaved haven’t different in two treatments and weeds such as Musk weed (Myagrum perfoliatum L.) was controlled as well. Wheat grain yield in Sulfosulfuron Metosulfuron treatment was less than 3.5 (t/ha) that not significant different in level 5 percent probability.
