Large sheets of black polyethylene plastic were to control nuisance aquatic vegetation in small farm ponds and lakes. The plastic was floated over vegetation beds and left unattended for a predetermined number of days. Adequate control of all species of Potomageton was achieved in 10 to 18 days. Ceratophyllum demersum was eliminated in the control plots in 18 to 28 days. Control was unsuccessful for Chara vulgaris and Saggattarius latifolia. All control plots were revegetated with filamentous algae within 30 days after the covering was removed.
