I have a 15 acre lake with about 3 acres covered in lily pads. We've tried Renovate 3 in the past to no avail. This year, we are trying Navigate but it doesn't seem to be working. We applied 300 lbs of it in that 3 acre section but it appears that the lily pads are still thriving and possibly even multiplying more. Do I need to apply a non-ionic surfactant prior to make it work better? I assumed since it's granular than nothing else was needed. Do we just need to up our rate? Any help is appreciated!

What you need is a bunch of muskrats. They will keep your lilys in check.

awlakes, IIRC Lotus, lilies, etc. can take a higher dose to control. We've had really good luck with it at the 100# per acre rate in shallower areas.

No surfactant is needed.
