To do so, samples were collected from maize fields located in 10 areas in the countryside of the city. The species were identified, contributing to the review of the literature. The following selected species were the most abundant ones: Amaranthus deflexus L., Bidens pilosa L., Commelina erecta L., Cynodon dactylon (L.) Pers., Cyperus hermaphroditus (Jacq.) Standl., Digitaria ciliaris (Retz.) Koeler, Digitaria nuda Schumach., Echinochloa colonum (L.) Link, Euphorbia heterophylla L., Galinsoga parviflora Cav., Polygonum punctatum Elliott, Portulaca oleracea L., Richardia brasiliensis B.A. Gomes, Scoparia dulcis L., Sida rhombifolia L., Stemodia verticillata (Mill.) Hassl. e Urochloa plantaginea (Link) R.D. Webster. Based on the data presented, we seek to encourage the public to change the common opinion about these species.
