Description
Summary:Sago pondweed (Potamogeton pectinatus L.) is a problem submersed weed of rivers, irrigation and drainage channels throughout temperate and subtropical regions of the world. Responses of this weed to low doses of diquat and cutting in the presence and absence of shade are described. Diquat at conditions concentrations ranging from 0.2 to 0.5 mg/l for 24 to 168 hours provided good control of sago pondweed under glasshouse conditions. Diquat at low doses of 0.1 and 0.2 mg/l and cutting alone, were not sufficient to provide acceptable control for normal management purposes, but low doses of diquat or cutting combined with 50 to 75% shade provided good control.
