The weed control with herbicides in beans crop was studied during 1970 year, in Campinas-SP, on a sandy-loam soil. The treatments employed were EPTC at 3.60 kg/ha, nitralin and trifluralin at 0.76 kg/ha, all applied in preplant i •porated; fluorodifen in preemergence at 3.00 kg/ha and a hoed check. Among the weeds presents in the experiment, Amaranthus viridis. L., Eleusine indica (L.) Gaertn. and Digitaria sanguinalis (L.) Scop. were very well controled by the herbicides in general. Good control was obtained by fluorodifen against Ageratum conyzoides L.. None efficiency was observed to Chenopodium ambrosioides L. and Ipomoea sp. by the chemicals. The herbic ides did not cause inju ry to the beans.
