Abstract: This research included three experiments, two experiments, in a wire green house and one experiment in irrigation canals, to study the effect of glyphosate (herbicide) mixed with nitrogenous additives on controlling water hyacint-weed --Eichhornia crassipes (Mart) Solms-Laub. Firstly, in a wire green house, the experiments were conducted during summer 1999 season at Agricultural Research Center , Giza. Results in the 1st experiment revealed that glyphosate at 90 g a.i./fed mixed with 2 % ammonium sulfate gave the highest reduction percentage of dry weight of water hyacint-plants (from 86-90.6% and 75% plant mortality). In the 2nd experiment, glyphosate at 180 g a.i./fed mixed with 2 % ammonium sulfate and or 2% urea caused the highest reduction percentage of dry weight of water hyacint plants (from 90.6- 94.4 % and 87.5% plant mortality). Secondly, in two irrigation canals chosen at Bahteem, Kalubia Governorate, were conducted during 1999 and 2000 summer seasons. Results showed that glyphosate at 180 g a.i./fed mixed with 2 % ammonium sulfate gave the highest reduction percentage of dry weight of water hyacint plants (from 93.86- 95.72 % and 89.13--89.74 % plant mortality).
