Use of herbicides to weed control is an available option in irrigated chickpea crop at the region Cienega of Chapala, Jalisco State, Mexico; thus, it is necessary generate technology because available information is not sufficient. In this work five herbicides: Alachlor, Oxyfluorfen, Pendimethalin, Prometryn and Trifluralin were evaluated and applied in pre-emergenge in order to know their control on the broadleaf weed species Amaranthus sp., Chenopodium spp., Portulaca oleracea, Physalis costomati and Euphorbia heterophylla in kabuli chickpea (Cicer arietinum L.) under irrigation conditions during the seasons 2003-04 and 2004-05. Treatments were tested in a randomized complete block design with four replications, plot size consisted on four rows 5 me long and 76 cm between rows. For each herbicide was calculated the percentage of each weed control. For each weed carried out analysis of variance and statistical test. Results: Statistical differences among herbicides treatments over the weed species were found, both different percentages of control. The most effective herbicides were pendimethalin 3.5 L/ha and trifluralin 3.5 L/ha, with percentages of control from 77 to 95. There were not visual effects of toxicity by herbicides over the chickpea crop.
