dc.descriptionAn experiment to compare the control of weeds with herbicides has been conducted in the Experimental Station of. lequetepeque Valley, district of Guadalupe, Province of Pacasmayo, Department of La bibertad, Peru. The treatments studied, in doses of is kg/ha woe dimetanzett inapiperolos to 1 65, 2.20 and 2.75 i a kglha, applied on the eighth day after transplanting; oxyfluorfen-A to the dose of 0.4 and 0.6 i a kg/ha, oxadiazon with the dose of 1.0 and 1.51 a kg/ha; bentiocarbo —simetrina to the dose of 1.8 and 3.0 i a kg/ha; oxifhtorfen— B in the dose of 0.4 and 0.6 i a kg/ha; penoxalin to the dose of 2 0 and 3.0 i a kg/ha; applied on the fourth day after transplanting Furthermore two witnesses were used, one unweeded and other weeded. The weeds that were recorded were Echinochloa crusgalli, Echinochloa colunum, Ischaenum rugosum, Eclipta alba, Cyperus esculents, Commelina fasciculata and in minor scale Leptochloa uninervia, Eriochioa pacifies, Eleusine indica, Ipomoea pentaphylla y Cyperus diffonnis. The treatments that showed to be efficient against gramineous were: unweeded witness, oxyfluorfen — A to the dose of 0.6 and 0.4 i a kg/ha oxyfluorfen — B with the dose of 0 6 i a kg/ha and penoxalin in its dose of 2 and 3 i a kg/ha, with per-centages of control of 99.83, 94.33, 79.89, 81 17, 76.45 and 70.04% respectively. There has been a good control against dicotyledonous with the unweeded witness treatments, oxyfluorfen — A to the dose of 0.6 i a kg/ha, bentiocarbo —:interline to the dose of 3 and 1.8 i a kg/ha and dimetametrina — piperofos to dose of 2 75 and 2.20 i a kg/ha. In regard to the grain production, the treatment that stood out were: unweed-ed witness, oxyfluorfen — A to the dose of 0 6 and 0.41 a kg/ha and penoxalin to the dose of 3 and 2 i a kg/ha, with yields of 8429, 6876, 6162, 5533_5525, and .5350 kern, respectively.
