Effect of Pendimethalin, Trifluralin and Terbutryn on Lolium multiflorum growing with barley during pre-emergence stage
2014
Alshallash, Khalid S.
Three herbicides, namely Pendimethalin, Trifluralin and Terbutryn were used to control the Italian ryegrass (Lolium multiflorum) associated with barley (Hordeum vulgare). The first herbicide Pendimethalin gave an effective control of L. multiflorum at doses as low as .125kg a.i/ha and few plants survived with rates 0.5kg a.i/ha. Effects on barley were severe; at dose of 0.25kg a.i/ha barley plants decreased by more than 50%. Trifluralin controlled ryegrass numbers up to 90% at 1kg/ha and caused little damage to barley plants. The last herbicide Terbutryn decreased the numbers of ryegrass plants quite effectively; it also damaged barley plants even at very low doses.
