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. By weed life cycle, annual weeds were the most common with 35 species (42.7%), followed by annual and biennial weeds with 8 species (9.8%), biennial weeds with 11 species (13.4%), biennial and perennial weeds with 2 species (2.4%), and perennial weeds with 26 species (31.7%). The number of non-selective herbicide applications in the sweet persimmon orchards was highest in the order of glyphosate-isopropylamine, glufosinate-ammonium, glyphosate-isopropylamine+MCPA, and glyphosate-isopropylamine+tiafenacil.
