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.

Cattails dying off
By Sam on September 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 September 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.

Good product, but not for every problem
By JD on May 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.

Lesser Celandine
By Sandy on April 19, 2011
Verified Purchase
When I first moved into my home, I thought the little yellow flowers in the natural part of my yard were beautiful. Over the years, they have moved closer and closer to my house until they are now suffocating my grass and plants. I researched my problem and discovered Rodeo is the preferred product to kill lesser celandine. I could not find Rodeo locally, so Googled the product. Domyownpestcontrol was one of the lowest prices. The information on their website gave me further details about my problem. The Rodeo arrived VERY, VERY QUICKLY. This was important since the time to spray lesser celandine is at its earliest emergence. I also ordered DyneAmic Surfactant. I was very nervous about mixing and spraying since I had never done this before. I am also very worried about my environment, but needed to rid this invasive plant. I became worried that the Rodeo was not doing anything. But after 2 weeks, the lesser celandine is dying off. Can't wait to see what emerges next spring.

Rodeo applied to reeds
By Marie on September 10, 2012I will begin by rating the product with three stars as it is too soon to know the final result. I purchased Rodeo to eradicate invasive reeds. I see the initial signs of the product working to kill the reeds but it is too soon to say if the product keeps them away for the year which it claimed to do. I hope it does, as the product is expensive. Very satisfied with the shipping time and condition of product upon arrival.

Are you up for a Rodeo
By Chili on June 26, 2012The product may actually be working on the cat tails!! Surfactant is key and I blended my own as the waxy leaves are quite resistant to having a water based solution adhere to them. It has been two weeks since my first application and I reworked the blend on one section an it appears to effective. Yay!

Use of Rodeo Herbicide
By Louise on June 28, 2011
Verified Purchase
The product I ordered came quickly and was exactly what I ordered. It arrived securely with no leaking. It killed everything I sprayed quickly and efficiently. The labeling was clear except on the front of the container it was not specific that it was intended to be used for both land and aquatic weeds, although inside the label there was a section that stated that. I did apply it with the recommended surfactant for better plant penetration. The weeds started dying within 4 days. I will be ordering it again.

Weed Control Looks Positive

Verified Purchase
Mixed it with a surfactant, as suggested, for control of phragmites near my shop (a very difficult and invasive plant). Initial results are promising from first spraying; a second application may be needed.

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.

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.

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.
August 10, 2010Nathan asked:
QIs there a quantity in acres that Rodeo 2.5 gallons should cover? Does Rodeo need to be diluted?
ATo determine how far one bottle of the Rodeo will go, you need to determine what type of vegetation you are treating and where you will be treating. We recommend that you review the Rodeo Product Label to determine the proper usage rate for your needs. Rodeo will need to be diluted with water as directed on the product label. You will also need to use a non-ionic surfactant such as Dyneamic in combination with the Rodeo for best results.
September 18, 2010Lora asked:
QIs this product legal in California, and can you ship it to California?
I'm having difficulty finding a product that can be used to control cattails in our California pond. They are out of control.
ARodeo is legal for us to sell into California, and we offer free shipping on all of our products. Rodeo is by far the most popular product for aquatic weeds such as cattails.
June 18, 2010Dennis asked:
Qif I use rodeo to treat aquatic primrose how long do I have to wait until I can plant other species?
AWe just started carrying herbicides due to customer request, but they are not our specialty. We would like to refer you to the manufacturer since they are the experts on their Rodeo product. The manufacturer is Dow AgroSciences and you can reach them at 800-992-5994.
