Efficiency of herbicides in weed control Mouse-Ear Chickweed (Cerastium sp.)And Cowherb(Vaccaria sp.) In wheat of Lorestan, Iran

ABSTRACT:Weed population such as Mouse-Ear Chickweed and Cowherb is increasing in wheat farms in Alashtar area, Lorestan, Iran ‎annually. So an experiment was conducted during order to study effects of different ‎herbicides on this weed population in the area in 2009-2010. The experimental design was a randomized complete block with four replications. The ‎treatments were including Teribenuron, 2-4-D, Solfusolfurun, Teribenuron + 2-4-D, ‎Mesosulfuron+ Sulfosulfuron, Bromocinil + MCPA and Triasolfurun + Terbuterin‎. ‎ In terms of percentage of overall compensation weed, the best treatments were (Teribenuron + 2-4-D), Terbuterin and Mesosulfuron+ Sulfosulfuron (total) that caused 98 and 91 damage percent respectively. Mouse-Ear Chickweed ‎ and Cowherb weed were well impressed by herbicides mixed (Teribenuron + 2-4-D) and (Mesosulfuron+ Sulfosulfuron‎) and damaged more than 98%. These weeds not controlled by herbicides Bromocinil‎, Triasolfurun + Terbuterin and ‎2-4-D and the weed density of these treatments were 8 plants per square meter and was caused reduce yield of wheat to 0.9 t/ha.
