Hello.

I have a pond with duckweed infestation. How do I reslove this problem please?

Thank you.

I use a fishing net as often as I can be bothered. It soon spreads out and
takes over again though. It does no harm on the compost heap

Thank you both for the response.

Is their any chemical you can purchase that can completely get rid of it?

I think anything that would kill the duckweed would also kill any other
plantlife in the pond.

and probably the fish too.

Once in a pond it's almost impossible to eradicate it without emptying the
pond, letting it dry, scrubbing it out, letting it dry, and carefully
washing all plants before you put them back. One piece not seen and it's
back to square one again.

Roundup will kill the duckweed but also any other plant it touches. And
no, it wont kill the fish!
A friend called in the environment agency to help him clear weed from a
fishing lake, the advice was 'roundup'. It apparently goes straight
through without causing any damage.

So what makes it appear and disappear? Water temperature, oxygen
content? Some years the IJsselmeer is carpeted with the stuff, other
years not.

Don't know, only guessing, but maybe if it rains a lot there is soil
washed into the water and so more nutrients.

I would like to see the scientific evidence for that statement before using
that weedkiller in a pond, effectively a closed environment.
If it is the case why all the fuss about it's use where human food is
concerned?

Roundup instructions says 'harmfull to fish'. Looks like the sieve is the way forward.

\thank you all for your help.

I've had a problem keeping it around: a few large koi or a bunch of biggish
goldfish will gobble it up.
Used to feed it to them! It doesn't get a chance to survive.
Overstook the pond with biggish fish.

Though remember the fish will take more than just the duckweed ..
