| Abstract: | The importance value and relative abundance of turf weeds in north Hunan were investigated, and an initial understanding of the species, distribution, and harm levels was gained. There are about 126 common species, of 115 genera and 36 families. 44 species were of the dominant families Compositae, Gramineae and Labiatae. The eight dominant species included Paspalum thunbergii, Cyperus rotundus , and Cynodon dactylon, which are also the target weeds for control. |
