Abstract	It is necessary to identify new herbicides with a wide spectrum of weed control for bean crops, and have an adequate security margin for this crop. The main objectives of this work were to evaluate the potential use of ethoxysulfuron herbicide on controlling weeds and three soybean cultivars between bean crop, as the tolerance of IAC Imperador bean cultivar to this herbicide. An experiment was conducted on field with a split-plot design. At the whole plot were allocated the doses of ethoxysulfuron (0; 10.4; 20.8; 41.6; 62.5; and 83.3 g ha-1) and, at the subplots, the three soybean cultivars (AMS Tibagi, Dow 5D634 e Nidera 5909) were allocated with weeds (Bidens spp., Ipomoea spp.). Additionally, it was included an extra treatment without weeds and herbicide application. The Ethoxysulfuron controlled Ipomoea spp. and soybean plants, but didn't control Bidens spp. It was found a differential tolerance between the soybean cultivars, and the AMS Tibagi cultivar showed to be slightly tolerant. Doses up to 20.8 g ha-1 are sufficient to satisfactorily control Ipomoea spp. and soybean plants, but not for Bidens spp. The herbicide provided an increment of bean yield, however, it wasn't enough to achieve the extra treatment yield. The IAC Imperador bean cultivar showed moderate tolerance to ethoxysulfuron, and its plants can recover quickly after any injurie.
