Abstract

This work presents the results of a field experiment carried out in Goiânia, State of Goiás, Brazil, to estimate the efficiency of herbicides in controlling weeds in onion crop of Texas Early Grano 502. Cyanazine controlled Portulaca oleracea, Amaranthus spp. till 45 days, and Commelina virginica. Eleusine indica and Brachiaria plantaginea till 30 days after application. Linuron controlled P. oleracea, Amaranthus spp. and B. plantaginea during 45 days. Both herbicides showed phytotoxicity decreasing the onion productivity.
