Treated about half the shoreline with Diquat on 5/23. Despite getting 1.5" of rain several hours later it is all totally dead on 5/25. I also tested on a small patch of cattails and it really did well there too. I added a round of bacteria treatment to help offset the nutrients now in the pond with all the dead Sago. We usually get small blooms during rainstorms due to all the lawn fertilizer from the surrounding lots.
I plan on leaving a patch of Sago alone in a large shallow area I can't reach with my sprayer. This will keep a nice area for the BG and LMB fry to hang out and feed in. I fear that treating with Sonar would turn it into a mud hole with little to no living plant life.
Thanks again for the advice Snipe!
