Answer
Hi Antony,
Thank you for your question and I'm sorry I couldn't get to you sooner.  You do have a problme if you have N. peltata.  It is an invasive water plant as you stated.  There is no natural predator that feeds on it that I could find.  Grass carp will not eat it.  It has been controlled by hand pulling and the use of Rodeo?  I researched USDA and several state government websites and there appears little anyone can do about the weed at this time.  I hope this helps.
