The Study of the efficiency of 5 herbicide on the 3 potato crop weed control

In order to determine the best herbicide composition of narrow leaf weed control, an experiment was carried out based on randomized complete block design included 4 replications.Treatments were: prosolphocarb with 2, 3,4,5 liter/ha, metribozin750gr/ha, pendimetalin 3,5 l/ha, Rihm solphoren40 and 60 gr /ha paraquat3 L/hand control. Measurements were done 3 times15, 30 and 45 days after treatment. According to the recorded results, the effect of herbicides on the Echinochloacrus galli (L.)P.Beauv, Sorghum halepense(L.) pers and Setaria viridis(L.)P.Beauv were significant and due to Duncan mean comparison, Paraquathad had the greatest effect on Echinochloacrus galli (L.)P.Beauv, Sorghum halepense(L.) pers and Setaria viridis(L.)P.Beauv in 30days after treatment and Sorghum halepense(L.) pers 30days after treatment.. paendymetalin5L/ha had the greatest effect on Echinochloacrus galli (L.)P.Beauv and Setaria viridis(L.)P.Beauv 30days and Sorghum halepense(L.) pers, Setaria viridis(L.)P.Beauv 45days after treatment. Also pendymetalin 3L/ha had the greatest effect on Echinochloacrus galli (L.)P.Beauv in the 45 days after treatment. It is concluded that Paraquat and Pendymetalin could be recommended as herbicide with the concentration of 5 L/Ha.
