Rodeo Herbicide

Rodeo Herbicide is a very popular glyphosphate herbicide for the control of aquatic weeds and plants. Rodeo Herbicide is effective on nearly all emergent plants like Cattails, Grasses, Bulrushes, Purple Loosestrife, Alligatorweed. Rodeo is systemic - kills the roots for multi year control. There is not a more economical way to control tall weeds. Mix the Rodeo concentrate with water and a non-ionic surfactant (See DyneAmic Surfactant) and apply by using a back pack or Chapin sprayer. For Cattail or Lily control wait until plants are mature. Apply to dry plants. No water use restrictions.

Product Features:

  • Top choice for emerged aquatic vegetation control
  • Broad-spectrum grass, broadleaf weed and brush control
  • Nonselective
  • Controls entire plant – roots and all
  • More convenient to use in difficult-to-reach areas than mechanical methods

    3 of 5 stars  Good product, but not for every problem
    By Jd in Central Oregon on 05/30/2011
    Verified Purchase

    I specifically bought this product to control weeds in my farm pond. It arrived quickly and well packaged; no problem there. Close reading of the Rodeo literature included with the product states, "will not control underwater plants, or those with foliage mostly underwater." Naturally, these were the plants that I wanted to control. Lesson learned: just because it says "aquacide" doesn't mean it controls all plants in the water.

    5 of 5 stars  Works great on Phragmites
    By Phragmite in Wisconsin area on 09/22/2010
    Verified Purchase

    Purchased because it is our state-approved for use on or near water---lakes and streams. Added the surfactant DyneAmic as recommended (which is also safe for use on water). Killed those very invasive tall water-loving phragmites. Used 3 oz to 2 gal of water and it worked well.

    4 of 5 stars  Cattails dying off
    By Sam in Newalla, OK on 09/26/2010
    Verified Purchase

    I have a small pond entirely filled with cattails. Tall ones, too--8-10ft. I sprayed about 1.25 gallons of this at a 5% solution and nearly everyone turned brown within 2 weeks. I will probably have to spray a second time because those things grow so fast.

    5 of 5 stars  Rodeo Aqua Killer
    By Marion in orlando, florida on 04/25/2014
    Verified Purchase

    This is great stuff but you must be very careful because even the slightest mist or overspray will kill anything growing close to the shoreline. I have used this product before and it prevented new growth for about 5-6 years. I would recommend this to anyone wanting to get rid of lily pads and other shoreline vegetation.

  • 5 of 5 stars  excellent product
    By Mark in fl on 07/14/2017

    Sprayed rodeo on lily pads and grasses in my lake. It took 3 days for the lily's and grass to start to turn brown. In a week they are completely brown, week and a half they are black. Very pleased with this product and highly recommend it. The lily's were thick, I was only able to fish with plastic worm or frog on top of the pads, now I can use top water plugs, shallow running crank baits etc... excellent product!

    5 of 5 stars  Kills Everything
    By Weed in Georgia on 08/27/2016

    My new favorite word in weed control, "Non Selective" it kills everything. I've used it primarily on pond and ditch perimeters as well on steep black berry covered banks. It takes a week or so to really hit stride and then everything rapidly turns brown and DIES. Bear in mind it requires user to mix with surfactant. I used turf-die as well to make it easier to see what I had sprayed.

    By Larry in Bremen, IN on 08/11/2016

    Applied with a backpack sprayer as directed for weeds around my 1 acre swimming pond edge and bank. Within 2 weeks, there was no weed left alive thanks to this product. I would recommend this safe product to anyone with a swimming pond.

    5 of 5 stars  GREAT product in my fight against Brazilian pepper tree!!
    By Paulina in Southwest FL coast on 03/24/2016

    Great product! Easy to use and great price (especially compared to other herbicides which are effective). Best part?! I live near the ocean and this is the only product rated for that!!! GET IT! I cut them down with a friend's sawzall and pruning blade, put this in a squeeze bottle, and then would immediately squeeze just enough to cover the cut area (MAKING SURE I got the cambium- the EFFECTIVE area to cover for this to work) and that's it!!! I even tried cutting 1-2 "trees" growing off of a main trunk- I saw the tree dying off in less than a week!!! Works AWESOME! Just follow precaution. Don't need to dilute (and shouldn't) to treat brazilian pepper cut treatment. Cannot be used for basil bark, just FYI.

    5 of 5 stars  THE best herbicide to eliminate lily pads!
    By Don in Bastrop, TX on 11/05/2015

    DoMyOwn claims this Rodeo is the most cost effective treatment for lily pads. They're right! And it's the easiest, too. Don't use it when water temps are high or you risk killing fish when the bacteria that decay the plants deplete the oxygen (water temps under 65 degrees are optimal -- fall is best time of year). See results in ten days. Use with blue dye (it's worth the cost). Mix per gallon: 2.66 oz of Rodeo, 1/2 oz of surfactant, 1/2 oz of dye (or less). They say this 2.5 gal jug will treat 4 acres, but it treats more than that. ...I tried other herbicide that costs MUCH more, but this stuff is the best.

    By Ron in Bexley, OH on 08/26/2015

    Needed a non-polluting herbicide to kill weeds on my rip rap near a small lake. Two applications of Rodeo mixed according to the the formula has knocked out every noxious weed and grass on my shoreline. Could not be easier to use. Safe and Effective.

QIs Rodeo Herbicide safe for use around dogs?
My dogs swim in and drink out of our pond, is this product safe for them and how long should I keep them away from the pond after using this product? Also, is it safe for the fish?

ARodeo Herbicide is labeld for use in ponds, streams, lakes and other bodies of water including bodies of water that are located in wildlife habitats. Products that would harm fish or other aquatic animals would indicate on the product label that the product could not be used near bodies of water. When used as directed on the product label Rodeo should be safe for dogs and other animals.

QIs Rodeo Herbicide safe for fish?
We have a large pond fed by a tributary from a river. Parrot feather is growing rapidly. Will this product help rid the pond of this invasive plant?

AYes, Rodeo is safe to use in ponds that have fish and other aquatic life. We just started carrying herbicides due to customer request, but they are not our specialty. We would like to refer you to the manufacturer to enquire about the parrot feather since they are the experts on their Rodeo product. The manufacturer is Dow AgroSciences, and you can reach them at 800-992-5994.

QHow long can you store Rodeo Herbicide without it losing effectiveness?
Rodeo seems to only come in 2.5 gallon containers and I don't need that much. If I buy it now, will it still be good next year and the year after?

ALike most of our herbicides, Rodeo has a shelf life of 3-5 years if kept at moderate temps. Mkae sure that the lid is tightly sealed before storing.

QRodeo vs Round up?
label active ingredients are the same yet one is labeled for aquatic use and the the other isn't, WHY ?

AIn cases where the active ingredients are the same but the usage is different there could be a couple of reasons, 1. The formula is different, meaning the base is different. The active ingredient is only one component of a finished product or 2. One company tested the product for specific uses and the other company did not. Use products in accordance with their product labels.

QCan I hand apply Rodeo to treat isolated phragmites plants?
We have recently landscaped our property. Isolated phragmites have popped up. I am concerned about wide spread spraying of Rodeo. Any suggestions?


Rodeo Herbicide is labeled for control of phragmites plants. It is labeled for partial control of phragmites in southeastern states. This is a glyphosate product and could potentially kill what it touches. We would recommend solely spraying the phragmites. You will use 2 2/3 fl. oz. per gallon of water.

QWhat percentage of Rodeo Herbicide would you use on grass growing in a pond? Do you wait till it's above the waterline?


Per the chart at the top of page 5 on the Rodeo Herbicide product label, you can use between 2/3 oz and 13 oz per gallon of water depending on the maturity of the target weed. For most weeds you want to get the product directly on the leaf surface as much as possible for the quickest result, however it will depend on the particular type of aquatic weed or grass if more specific treatment steps need to be taken. Please review the product label for specific instructions for your needs.

QCan you start the application of Rodeo Herbicide in the spring on phragmites or do you have to wait till late summer?
Just looking for the most effective time to apply. Some sites mention waiting until late summer, but I'd like to start as the plants emerge because they are easier to access. I'm in Virginia off the Chesapeake on a tidal river. Thanks for your help.

QHow far away should well water be from a lake area treated with Rodeo Herbicide?

QHow do I use Rodeo Herbicide with Crossbow?


Just to be clear, Crossbow Herbicide is not labeled for aquatic use like the Rodeo Herbicide is. So if you are using this in or around water where you would have run off we would not recommend mixing these two products. If not then you would mix them at 1 1/3 - 5 1/3 oz of Crossbow†per gallon of water, and 2 2/3 oz of Rodeo per gallon. We always recommend you do a small treatment area to be sure that these combined products will not cause any damage.†

QWill spraying weeds now with Rodeo Herbicide prevent weed growth come spring?
The water is let down on our lake in Oct for winter, exposing all the lake weeds and making them much more accessible...but the weeds have all now gone dormant. Will spraying the weeds now have any effective kill come spring? The lake will fill with water once again come April. Would an application of Rodeo be more advisable in early April before the water rises, or does the weed killer really only work on active growing green plants?


No, Rodeo Herbicide will only kill actively growing weeds and will not stay in the soil until Spring.†
