Abstract- The present study was carried out at kom-Ombo Agricultural Research Station farm, Aswan Governorate, Agricultural Research Center, Giza, Egypt, to evaluate the herbicides treatments on different weeds species in Sugarcane fields and their control methods on yield and quality of sugarcane . The obtained results revealed that the weed species observed in the sugarcane field were twelve weed species belonging to nine families. Out of them three species belong to the broad leaved perennial weeds (Convolulus arvensis , Sesbania sesban , Ipomoea cairica) while six species belong to the broad- leaved annual weeds ( Hibiscus trionum , Corchorus sp, Euphorbia geniculate Ortega., Portulaca oleraceae , Sida alba , Dutura stramonium ) were observed. The grass perennial weeds were presented by two species (Cyperus rotundus , Cynodon dactylon ), while only one grass annual weed species were found ( Digitari sanguinalis). Weed control treatments had a significant affected on broad leaved, narrow, and total weeds (g/m2) in both season. The application of herbicides affected the weed type and density but the response of different types of weeds varied to different herbicides. Also, Weed control by herbicides treatments had a significant effect on cane yield (ton/fed.) , sugarcane yield (ton/fed.), brix, sucrose and purity percentage in sugarcane .
