This study was conducted to identify the current status of weed occurrence in sweet persimmon orchards in Changwon, Gyeongnam province. As a result of investigating weeds occurring a total of 33 families and 82 species of weeds were identified. Asteraceae 17 species (20.7%), Poaceae 9 species (11.0%), Polygonaceae 6 species (7.3%), and Caryophyllaceae 4 species (4.9%) in the order of occurrence. Bidens pilosa in Asteraceae, Digitaria violascens in Poaceae, and Persicaria longiseta in Polygonaceae were the most dominant species.
