Dear Sir or Madam: I have a one acre pond that suffered last year from an overgrowth of duckweed. It appears that the pond will have the same problem this year as I'm beginning to see new duckweed growth now that it is getting warmer. What is the recommended method for clearing the duckweed from my ponds water. My pond is located at 500 Klee Mill Rd Sykesville Maryland (the duckweed issue can be seen in the google or bing satellite photo's). Any help would be greatly appreciated. http://binged.it/1hCdhtw Philip Ceary

In our area duck weed is particularly prevalent in ponds that receive fertilizer or manure run off.

Purdue has an excellent fact sheet that discusses both manual and chemical control options http://www.btny.purdue.edu/pubs/apm/apm-2-w.pdf
