I use an old metal flour sieve attached to a cane to scoop the duckweed from the surface. Any invertebrates etc that get scooped up can easily be released back into the water. If your pond is too big for this then use a hose with a sprinkler rose to 'push' the duckweed next to the edge so you can get it more easily from there,
