In: Mansoura Unviersity Journal of Agricultural Sciences 2007.v.32(7)Summary: Two field experiments were carried out in Horticulture Research Station at EI-Kanater , Kalubia Governorate during 2003 and 2004 summer seasons at Navel orange trees 15 years old orchard naturally heavily infested with annual and perennial weeds. Each experiment included eleven treatments in a complete randomized block design with four replicates. Four nozzles were applied in these treatments i.e. hollow cone ( conventional method ) at rates of glyphosate ( Round up 48 %WSC) 4.0.2.5 L/fed. and 1.25 L/fed., with TK1 nozzle at 2.5 and 1.25 L/fed. Flat and fan E 04 - 80 nozzle at 2.5 and 1.25 L/fed and deflector yellow nozzle at 2.5 and 1.25 L/fed. as compared with hand hoeing and unweeded check. Water volumes were 200, 125. 102 and 50 L/fed. with the previous nozzles in the same respective.
