    Anyway I was going to say I use WEED PLEX PRO, and it works really well.

    Rodeo is just Roundup without the surfactants. It is 25% stronger or has 25% more AI. But cat tails can be hard to kill with straight Rodeo. There is an excellent Aquatic Surfactant called DLZ for Droplet Landing Zone that costs more per gallon than the Rodeo. But it makes the Rodeo kill cattails with the first treatment. BTW Aqua Star or Aqua Master are a genetic Rodeo at lesser cost.

    PS 2,4-D also comes as a Aquatic.

    Cattails are a perrenial with a rhizome. Spraying anytime may kill the foliage, but not the plant. The greatest success comes in spraying glyphosate in the fall after the plant has flowered and as the plant begins to strengthen its root system for overwintering. Dependant upon where you are at in Michigan, that preferred time for spraying may be in September. Use an aquatic labeled glyphosate, add surfactant, spray in the fall and you'll have good results.

    best way I have found to get rid of cattails is to use an excavator and scrape off the top couple inches of soil.

    don't use reward/weed plex thinking it is going to kill catails.. it will burn them down fast, but will only control them for the the most part (yes there are exceptions) i use rodeo with great sucsess, and i use pentabark as a surfactant. reward is best used to control subsurface plants, that rodeo cant control due to them being under water.

    Stihl used to make a pole hedge trimmer that has a cutting head at a 45% fixed angle. While I find that model to be hard to trim hedges with, it is perfect for pond weed cutting. It does require cleaning and oiling after use.
