I'm looking to get a product to clear some of my ponds banks of watershield.

Does anyone have any expereince using Navigate and/or Sculpin G? Which one works the best?

I'm thinking of using a granular 2, 4-d product this spring on about 40% of my ponds banks to kill/supress the watershield before it really gets going. By late summer the banks of my pond are covered and it makes it difficult to get at the bass and I expect it makes it difficult for the bass to get at forage. Want to clear a good portion of the shallower end of ponds bank. Plan to leave alone large sections of watershield be to provide a refuge for small fish/shade/oxygen.
