A new report on turf weed occurrence, and turf weed control measures in Guangzhou

Investigation in different areas of Guangzhou from 2001-2002 found 145 weed species that belong to 122 genera and 50 families. 82.76% of them were broad-leaf weeds, and only 14.48% of them were monocotyledon weeds. Weeds causing serious harm included Alternanthera sessilis, Alternanthera philoxeroides, Oxalis corymbosa, Oxalis corniculata, Hydrocotyle sibthorpioides, Centella asiatica, Eclipta prostrata, Lindernia antipoda, Cyperus rotundus, Kyllinga brevifolia, Cynodon dactylon, and Digitaria sanguinalis. Compared with the 1995 investigation results, weed species had increased, and weed species causing serious harm experienced quite big change. In light of weed evolvement, this paper also analyses control measures.
