Abstract
Studies were carried out on the evaluation of Sequential Application of herbicides for broad and grass weed management in durum wheat at Debre Zeit, Akaki and Alem Tena Districts, Oromia Regional State, Ethiopia under main season condition, during 20012-14 for two years to evaluate the efficacy of different post emergence herbicides on weeds. The experiment was laid out in Randomized Complete Block design (RCBD) with three replications, with plot size of 3.60m x 4m (14.4m2). Four different herbicides were applied as post emergence via: 2, 4-D and Flurasulam (75g/L, Flumelsulam (100g/L) (Derbi175 SC) herbicides were applied at 28days after crop emergence with rate of (1 L/ha and 0.06L/ha) respectively, Pyroxsulam (Pallas*45 OD) and Mesosulfuron methyl+Iodosulfuron methyl sodium (Atlantis 37.5 OD) at 35days after crop emergence with rate of (0.45 L/ha and l L/ha). Twice hand weeding as standard check and an untreated control was also included in the trial. All herbicides significantly decreased weed population over control and maximum grain yield were recorded from sequential herbicidal applications of 2, 4-D and Pyroxsulam, followed by Flurasulam (75g, Flumelsulam (100g/l) (2849 and 2818 kg/ha) respectively. All the herbicidal applications out yielded the control. It is thus recommended that an integration of Pyroxsulam (Pallas*45 OD) and (Mesosulfuron methyl+Iodosulfuron methyl sodium) Atlantis 37.5 OD and 2, 4-D and Flurasulam (75g/L, Flumelsulam (100g/L) (Derbi175 SC) for offering control of broad leaf and grassy weeds and increase grain yield of wheat.
