Posted By: John Monroe How long does it take cattails to die? - 04/05/12 05:16 AM
I first sprayed some cattails in a small area selected area with GlyphoMate 41 about two weeks ago, using 1 oz. to 1 gal. ratio. All that happened was a few of the leaves draped down and fell into the water. So last week I put 8 oz to 1 gal. and sprayed again. I am still not seeing much happening. Is something wrong with what I am doing or is this the way it happens, very slowly?

Also I was happy I was getting curly leaf pond weed last year and wanted to see it's effects on FA this summer but it is coming on way too fast so I'm putting in 6 GC to slow it down a little bit, and part of my old standby solution for FA, KOI.


John, You have to give it a little more time to get into the roots. Then you'll be be happy. 1 oz sounds kinda weak to me but that last shot you gave them should do the trick.

I've found that if I add extra surfactane to the glyphosate mix it works on cattails much faster.

I agree with esshup. I sprayed mine several times before they finally died and used a surfactant every time. Like most reedy plants, I believe the absorption rate is a little slower.

I also think it all works better when the temps rise a little.

I am a commercial full service Certified Pesticide applicator in Fla. and Yes cat tail can be hard to control and will come back. I find it is better to use the Aquatic formulation of 53.4% Glyphosate instead of the non aquatic 41%. Application Equipment can make a big difference in response also.

My Rate for Cat tails is 4 oz of Aquatic 53.4% Glyphosate (Rodeo, Aqua star etc)and 2/3 oz of MSO (methylated Seed Oil) Per gallon. I use a 12V Fimco 2 GPM spray pump and a zero degree fan tip or a 15 degree fan tip. I soak the cat tails down making sure I get as close to 100% coverage as possible. Response is slow and I start to see a response in about 10 days. It might take an other 10 days to see a major brown out.

Next step is to mechanically remove as much of the Cat tails as possible. Of course regular monthly follow up treatment are advisable. Cat tail WILL come back a few times before they are totally controlled

PS Tractor Supply sells smaller 12V sprayers and tank set ups CHEAP. About $ 100 for a 15 gallon unit. These can be carried on ATV or lawn mowers etc and powered by their batteries. Be sure to add an extra 50 ft of hose or more to reach the treatment area. As a commercial applicator I have several 12V set ups on either ATV or boat. But I have one 15 gallon unit on wheels I pull around smaller ponds where I don't want to use a back pack or a ATV. I use a small $ 20.00 Sealed Gel Battery from TSC to power it. You might find these batteries in the electric fence section. They are small and easy to carry, but do the job for a short period of time. I charge it off my truck lighter socket.

For Terrestrial application I have a 65 gallon 12V Fimco 2 GPM pump and a 300 ft hose reel. My point being the power of these cheap throw away type Fimco Pumps to push 300 ft of hose and still do production type work. Let me also qualify my statement by saying I have Cab Over Trucks with PTO Warner Hydra cel 25 pumps. While the 12V pump don't put out like a PTO pump they still do a fine job. I also do many modication to my equipment. I like to use a Pressure washer Gun because of the nozzles.

Good Luck

For clarification sake, GLYPHOMATE 41 is a 41% a.i. aquatic labeled glyphosate formulation - and contains a surfactant-load, though not of the MSO variety.
Also, newer variations of glyphosate exist (namely REFUGE and TOUCHDOWN PRO) that possess different charateristics in comparison to "traditional" aquatic glyphosate formulations (ie RODEO, AQUAMASTER, AQUANEAT, etc) - and often provide exceptional results more quickly. However, with any glyphosate formulation, excessive mix-rates (esp those that exceed labeled rates) may yield quicker "visual effects", but undermine the treatment's long-term results.

Kelly:

Thanks for the info on the newer products. I didn't know that!
#1Ric & Kelly....Great info. Thanks!

I usually pull mine by hand a couple times a year. Most of it comes up by the root but breaks apart from the runner which will re-grow. But pulling it twice a year works out pretty well for me.
It has been about three weeks now since I first sprayed my cattails and a few lilies and I am slowly seeing some results. I'm just spraying around my deck but I do have a 15 gal. 12 volt sprayer that can be bought for only $69 on sale and they are a real workhorse for being so cheap. I have used one straped to the back of my lawn more for years and if need be I can put it in my boat for doing larger spraying in the pond. But for the most part I like lots of vegitation in my pond to observe nature.
