| Abstract | ||||
| Two field tnals were conducted to study the effect of six post-emergence “erbicides on controlling weeds and increasing wheat’s productivity. Two herbicides (Sinai 10 SC & Lentagran 600 EC) were performed for controlling broad leave weeds, iloxan EC and Grasp EC for grasses, meanwhile, Panther SC and Arelon FL were ised for controlling both types of weed. The herbicides were applied as a foliar application either alone or followed by each other subsequently at different rates of concentration. Most of the herbicides substantially suppressed growth and deielopment of a wide range of mono and dicotyledonous weeds associated with wtieat. Spraying Panther and Arelon herbicides alone at 0.6 and 1.25 LJfed., respectively were the most effective for controlling broad (up to 98%) or narrow (up to 36%) leave weeds and increasing yield productivity by up to 71% as compared with Dther herbicides or control. Using Sinai 10 SC or Lentagran 600 EC subŠequently with lioxan EC and Grasp EC at low concentrations (< recommended dose) gave, to a large extent, similar results to those herbicides applied alone at high concentrations for reducing weed growth and increasing wheat grain yield (53-62%) as compared with control. Hand weeding once controlled broad leave weeds and grasses by 45- 93% and increasing wheat yield by 47-53%. The herbicides increased the NPK contents in wheat’s grain, irrespective of the rate and sort of application either compared with hand weeding or control. It has been suggested that applying more than one selective herbicide at low concentrations would be more efficient for controlling a wide range of weeds associated with wheat rather than being applied alone at higher concéntrations. | ||||
