This is my year to kill off some of my spatterdock. I've enjoyed them over the years but their too thick now. I didn't like the high prices I was seeing for the chemicals to kill spatterdock and cattail. The main ingredient was 41% glyphosate, and that is in Eliminator, $8 concentrate makes 10 gallon at Walmart. What was missing was a succulent so I used Walmarts Great Value rinse agent for dishwashers, $4. I made a strong mix of this and tried it on a few spatterdock and cattails last year and it worked ok. I sprayed at my deck where I could observe any new growth from the plants I sprayed, and didn't see any. I'm also mixing in blue marking dye to mark only the ones I want to kill. My spatterdock are just starting to come up so I plan to spot spray them from my boat as they come to the surface.
