The sampled area corresponds to 13.1 ha and was divided into grid of 50 X 50 m, totaling 53 points. In each point do was randomly thrown a wooden square with 1m side (1 m2). We evaluated the following parameters: relative frequency, relative density, relative abundance and index of economic importance. Were identified 13 weed species on 9 families and the most important index of economic importance, were Brachiaria decumbens e Digitaria horizontalis So the weeds identified in the survey are considered the most common and problematic the productivity of cassava.
