Popis: A 2-year field study was conducted to determine the effects of periodic removal of topgrowth on tuber production and persistence of sago pondweed (Potamogeton pectinatus L.) in an irrigation canal. Plots were treated at 1, 2, and 4-week intervals throughout the irrigation season with aromatic solvent to kill the topgrowth. The tuber population was determined before the treatments began and at the end of each season. At the end of the first season, the number of tubers was reduced 78, 87, and 54% in the plots treated at 1, 2, and 4-week intervals, respectively. After two seasons, the number of tubers was reduced 91, 81, and 80%, respectively. All treatments controlled sago pondweed topgrowth effectively, but none eliminated the tubers completely.
