Product Overview

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.

    Good product, but not for every problem

    By Jd 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.

    Cattails dying off

    By Sam 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.

    Works great on Phragmites

    By Phragmite 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.

    Rodeo Aqua Killer

    By Marion 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.

    The Rodeo Herbicide mixed with DyneAmic Surfactant are doing a good job killing my Phragmites. I used a 10% mix.

How much Rodeo to 1 gallon of water and how much surfactant do I dilute with it?

I see that Rodeo is recommended to mix 2 and 2/3 oz per gallon of water, but surfactant is listed as between 0.12oz and 0.64 oz. Will be spraying aquatic weed alligator weed.

You will use 2 2/3 fl. oz. of Rodeo Herbicide per gallon of water. You can use about 1/3 fl. oz. of Kinetic Nonionic Surfactant.

Is 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?

Yes, 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.
