Several species of the genus Oxalis, such as Oxalis corniculata and Oxalis latifolia, are part of the Oxalidaceae family which have the ability to produce allelopathic compounds against horticultural crops and other weeds. To determine the relationship and interaction between grass weeds that cover the land and Oxalidaceae weeds, observations were made on species diversity, coverage, and distribution of land cover crops in the area around the sampling site for Oxalidaceae weeds. Results show that the three species with the highest cover are Axonopus compressus, grass in the family Poaceae, and Oxalis corniculata, with 23.18, 17.57, and 7.97%, respectively. Among the 33 species observed, there are 2 species of Oxalidaceae from the genus Oxalis, namely, O. corniculata and O. latifolia. In contrast to Oxalis corniculata, Oxalis latifolia (Broadleaf Wood sorrel) only cover 5,41% of the garden area. O. corniculata or Creeping wood sorrel is the only ground vegetation and weed found in 80% of the observed plots. In conclusion, Oxalis weed is a cosmopolitan weed and its potential as a biological control for other weeds can be further investigated. © 2023 American Institute of Physics Inc..
