Conteúdo:	Composition and level of weed infestation interfere with crop yieldand increase production costs. This study aimed to identify weed composition andinfestation in corn grown with different plant populations, single, and intercroppedwith palisade grass. The phytosociological method was used to evaluate density,frequency, dominance, and infestation level of weeds in single and intercroppedcorn, a with conventional (0.90 m) and reduced (0.45 m) spacing, and low and highplant population in Dourados, MS, Brazil. Commelina benghalensis,Echinochloa spp., and Euphorbia heterophylla were the species most found in thetreatments. Single corn with higher plant population decreased weed occurrence.Treatments with palisade grass under a reduced spacing showed lower absoluteweed infestation (about 75%) when compared to single corn. Weed infestation waslower in the intercropping of corn with palisade grass, with more pronounced effectunder a reduced spacing.
