I had a client give me a bottle of this and said he wanted us to use large quantities of it to kill some existing cattails. Looking at the label, the main ingredient in both is Glyphosate. Is it just a difference in concentration?
Are there other chemicals in tiny quantities in there to make it slightly different?
Well, actually Paul, that's where I was thinking of using it. Here's a link to the MSDS for Rodeo http://www.tcweed.org/pdf's/rodeomsds.pdf - looks like it's designed as an aquatic weed killer, but says to keep it out of waterways. Hard to kill aquatic weeds without going near the water....
You saw that other pic - there are millions of cattails. Is there something else that might work?
My understanding of the difference between rodeo and roundup is in the surfactant's. Rodeo is used to control cattails while roundup cannot be used near waterways because the surfactant's used are toxic to fish. I also believe rodeo is now called aquamaster. I find it funny that the label only identifies the active ingredients and not all the other chemicals that a product contains, that can affect its use.
I've been told the same thing that dan just metioned......bascially its the lack of surfactants (from my memory, surfactants clog up the gills of fish and damage other aquatic animals or something like that)
For some reason, I thought roundup made a formula that was surfactant free and for wet areas.....something like roundup T/O or something?
Hmm, this thread is misleading. I was hoping that someone was talking about horses, cattle and cowboy skills.
