摘要

ABSTRACT Delta arrowhead [Sagittaria platyphylla (Engelm.) J.G. Sm.] is an emergent, aquatic plant, originating from North America, which has invaded aquatic environments in Australia. The plant is particularly problematic in southeast Australia, where it invades earthen irrigation channels and drains. Hydraulic capacity is subsequently reduced, leading to a reduction in the efficiency of water delivery. Options for controlling delta arrowhead in irrigation channels and drains are currently und.
