Will Sendero Kill Cactus

spray herbicide mixture By applying the herbicide Tordon 22KTM on pricklypear and other cacti, you can achieve 76 to 100% rootkill. Picloram, a component of this product, destroys prickly pear and other cactus.

What is killed with Sendero herbicide?

Other herbicides don’t operate like Sendero does. However, during the treatment season, it offers residual activity to suppress later-emerging broadleaf weed species, such as invasive thistles, broomweed, croton, and bitter sneezeweed.

What destroys the cactus root?

There are primarily two methods for doing this. The first method is to remove them using chemicals. Physical removal is the second technique. Either approach can be risky if used incorrectly, but both are generally safe if used correctly.

What you should know about both techniques for clearing cacti from your yard is as follows:

Killing a Cactus with Herbicide

Herbicide combinations come in a variety of forms with varied components. Picloram is one such component that you should keep an eye out for. A large fraction of some varieties of cactus can be eliminated with the aid of a herbicide containing picloram.

To aid in absorption, some experts advise incorporating a small amount of dish soap into your picloram herbicide mixture. Since you’ll be spraying it on your cactus, it’s also a good idea to apply some dye. The dye will show you which places you’ve covered and which areas you’ve missed. Blue is a useful dye color to use:

It will assist if the plant is physically harmed before you spray this on the cactus. To make some nicks in the cactus so that the spray may better penetrate the plant’s interior rather than just sitting on the exterior, you can use any form of axe, a shovel, or any pointed object.

Although the insider information helps move things forward more quickly, the parts you spray on the exterior will still be effective.

How to Get Rid of Cactus Without Chemicals

Overwatering cacti or succulent plants is the most typical technique to harm them. Cacti that receive too much water will become mushy and essentially decompose. That doesn’t really help you much in this situation because you still need to dispose of it, which brings us to the main problem with this strategy.

Physical removal, or just getting rid of a cactus, is your only option if you don’t want to employ chemicals to deal with it. After that, you may either discard it in the garage or dispose of it as regular yard garbage.

Depending on where you reside, different cities will give varying guidance or services for this, so you might want to check your local laws. Because it is organic and contains a lot of water, cacti typically shrivel into a much smaller state over time. Be careful, though, because it will be really sharp in the interim.

One part gin, one part vinegar, and one part water make up a DIY cactus killer recipe. This can be put in a spray bottle, sprayed, or poured over the plant’s base.

Here are some helpful suggestions on how to remove a cactus from your yard safely and effectively if you want to avoid using chemicals.

How to Remove a Cactus From Your Yard

After spraying, you still need to get rid of the plant once it has died. In fact, you still need to get rid of it whether or not you sprayed it. Here are some ideas on that as well as advice for getting it off the ground.

The degree of defense you’ll need against its thorns will mostly rely on how big the cactus is, how many of them there are, and what kind they are. Some are far pricklier than others!

The first step is to make sure that you have no exposed flesh anywhere on your body since pricklies are drawn to exposed skin like a magnet. Wear protective eyewear. Put on sturdy boots or shoes, preferably ones with a thick rubber sole.

It is beneficial to cut up a huge cactus when working with it (carefully.) For this, you can use almost any kind of shovel or a blade of some sort, like a machete. Be cautious as you swing and hack at it; at the very least, you should wear eye protection, and if not that, a full face mask.

Murphy’s Law holds that if there is any region of exposed skin on your body, even if it is only covered by a t-shirt, you will inevitably get stung by a cactus there.

Therefore, start by carefully wrapping some of the pieces you remove by chopping at it. Put on thick, hefty gloves with plenty of wrist and arm protection. You’ll be safer if your clothes is more substantial and dense.

The bits you take out of the cactus store up well in cardboard boxes. It’s time to start digging when all that’s left is the plant’s underground roots and bottom portion.

As much of the root system as you can should be dug up. The more you may get, the less probable it is to continue existing, let alone thriving or regrowing. Its size will vary from plant to plant.

Cactus plants: Will Roundup harm them?

Cactus use is not recommended for Roundup QuickPRO. However, it might take care of them. We would suggest a product like Tordon RTU Specialty Herbicide or Remedy Ultra Herbicide. Each one of these controls tougher plants and brush, whereas Roundup mostly targets broadleaf weeds.

What can I use as a cactus spray?

Works best: In relatively small stands of tasajillo, pricklypear, and other cacti.

When to use: You can use the Brush Brusters pad or stem spray technique all year long. Surmount or Trooper Pro herbicides, which are used in Brush Busters, are absorbed by the pads and stems as well as through the roots after rains have carried the herbicide into the soil. Following spraying, prolonged dry weather may lower plant mortality.

Prepare equipment

Prickly pear control can be done with any kind of sprayer, although ATV-mounted or backpack sprayers work best. Sprayers mounted on ATVs work best for big regions whereas backpack sprayers are excellent for small areas with dense vegetation. Ensure that your sprayer has a nozzle that can provide a coarse spray (large droplets). For large plants, a fan-type nozzle might be more effective, but for smaller plants, an adjustable conjet nozzle like the Spraying Systems Co. Conejet 5500-X6 or -X8 will be more effective.

Mix herbicide spray

Spraying a herbicide with the active components picloram + fluroxypyr will cause pricklypear and other cacti to die by 76 to 100 percent.

Add the herbicide to the water at a concentration of 1% to create the spray mixture. Add a non-ionic surfactant to the spray mixture to achieve adequate pad and stem coverage (see table below). In order to label plants that have been sprayed and check whether you are receiving enough spray on the green pads or stems, it will also be helpful to add a spray marking dye, such as Hi-LiteTM Blue Dye.

Spray the Pricklypear

Anytime of the year, with the exception of exceptionally cold weather, is suitable for spraying prickly pears. Apply until the point where the plant’s pads and stems are moist but not until runoff occurs. If both sides of the pricklypear pads are sprayed, results will come more quickly and consistently. The Hi-Light Blue dye will work best on the plants if it is applied in the winter, when the grass surrounding the prickly pear plants is dormant from the cold.

Keep these points in mind:

  • The Texas Department of Agriculture’s Pesticide Applicator License is necessary to acquire and use any herbicide that contains the active component picloram. For information about licenses, contact your county extension agent.
  • Always adhere to herbicide label instructions.
  • Pricklypears expire extremely gradually. Total plant mortality may not happen for up to two to three years after treatment.
  • Spraying onto damp pads or stems is not advised.
  • When the temperature is below 60 F, do not spray.
  • If you are operating directly upwind of attractive trees, bushes, or vulnerable crops, avoid spraying.
  • If you are within 100 feet of a known sinkhole where the herbicide could infiltrate subterranean water aquifers, do not spray.
  • Spraying dense pricklypear or other cacti growing beneath desirable trees like live oak or pecan could cause damage to those trees.
  • As prickly pear size and density increase, treatment costs rise quickly.
  • Within 20 yards of endangered plants, do not spray. If you require details about endangered or threatened plants in your region, contact the U.S. Fish and Wildlife Service.
  • Quail may use large pricklypear bushes as nesting grounds in places with little bunchgrass. Prickly pear is also a food source for other animals like deer and javelin.

How do you remove a big cactus?

Prior to removal, cut huge cacti using an axe or chainsaw. Cut it into manageable pieces with the axe. Make sure to remove every piece of the cacti you cut by carefully pulling away each section. Each item should be put into a cardboard box with thick walls after being removed. Small fragments of several different cacti will eventually reappear. As you cut the pieces, box them to keep them off the ground.

Is Sendero superior to a cure?

Comparing Sendero herbicide to a combination of Remedy Ultra and Reclaim herbicides, Sendero herbicide has shown to be more reliable and effective.

1 However, land managers and applicators still need to make applications at the appropriate periods even with this efficient technique for mesquite control.

Soil temperature must be at least 75 F in order to effectively control mesquite with Sendero or any other herbicide. A big rain after a dry season, low humidity, and drought stress should all be avoided while treating. Avoid spraying mesquite trees when their beans are actively elongating.

1Cummings, D. C., P. L. Burch, and V. B. Langston. 2012. GF-2791 [Sendero] is a novel herbicide for the control of honey mesquite (Prosopis glandulosa) in southwest rangelands. It contains aminopyralid and clopyralid. Presentation of technical data at the Society for Range Management’s 65th Annual Meeting and Trade Show in Spokane, Washington.

With what do you combine Sendero?

blend herbicides Typically, spraying with Sendero (active ingredients: Aminopyralid and Clopyralid) or a mixture of Triclopyr ester (trade names: Remedy Ultra, Clear Pasture, Triclopyr R&P, and Triclopyr 4EC) coupled with Clopyralid can result in 70-100 percent death (trade names: Pyramid and Clopyralid 3).

How can cacti in pastures be eliminated?

Spraying or mechanical removal using a grubbing hoe (for isolated plants) or a skid-loader are the two methods that are typically advised for getting rid of prickly pear (large stands). Occasionally, controlled burns can be employed, but fire is not selective and burning needs a lot of supplementary dry brush (cactus don’t burn well). Burn prohibitions that are in effect across a large portion of the Southwest United States also rule out most people using this technique.

Depending on the scale of the cactus growth and the surrounding vegetation, spraying and grubbing each have their own advantages and disadvantages. Rainfall and temperature can also affect how well your strategy works. Cost might also be a significant factor.

Grubbing or the top-removal method

The most efficient, speediest, and environmentally responsible method of removing substantial stands of pricklypear is generally thought to involve digging up cactus with a skid-loader. However, it can be expensive, with charges for the operator and equipment ranging from $80 to $100 per hour. For tackling substantial cactus stands, Michael Dalrymple, a Mills County, Texas, contractor who specialized in brush removal, advises using a skid-loader fitted with a rock rake. The rock rake’s tines allow dirt to fall back to the ground, decreasing top soil loss and disposal weight in the process. Using this method, the operator is able to cut out several inches of the root, which is sufficient to kill the plant.

In order to bury the uprooted cactus, Dalrymple advises trenching a pit and adding 18 to 24 inches of earth. Cactus that has been heaped up will re-root and develop into an impenetrable mound, unlike cedar that can be stacked up and burned.

It’s crucial to gather as many of the dropped pads as you can. Every pad that is left on the ground has the capacity to take root and grow into a new cactus.

Although mechanical removal can be done at any time of the year, the best times are fall and early winter to allow for reseeding in time for the growing season.


Spraying works well on single plants and lean pricklypear growths. With ground-level spraying, it is practically impossible to completely remove a large, thick stand because pads and stems must be thoroughly coated. Additionally, it’s crucial to avoid spraying close to mature trees and vegetation because those plants’ roots can absorb the toxin.

Large stands of cactus that are far enough away from trees and other valuable flora that the herbicide drift won’t harm or kill are occasionally advised to be sprayed from the air.

Although cacti can be sprayed at any time of the year, most experts advise spraying herbicides in warm weather when rain is forecast since moisture makes the poison easier to absorb.

Results can take six to eight months to appear, and many applications are frequently needed to completely eradicate the cactus.

Although the Dow AgroSciences subsidiary of Dow Chemicals produces a number of efficient herbicides, two of the best-known, Tordon 22K and Surmount, are limited by the federal government and need a license to be used. For spot maintenance, several ranchers advise Dow’s PastureGard HL herbicide because it can be applied without a license. Employing a licensed applicator can cost upwards of $35 per hour plus the herbicide depending on where you live.

Cactus needles: How can you get rid of them?

Cactus spines can be easily removed with a pair of tweezers if you manage to get one or two stuck in the flesh. But what if you end up being one of the unfortunate people who gets stuck with a hand, foot, or butt full of needles? Elmer’s Glue works well for this, just spread a thin layer of it over the surface.

Once the glue has had time to dry completely, allow it to sit for a while before peeling it off. Your skin-piercing needles will rise to the surface and be pulled out by the glue. If you get a good foot- or handful, you might need to repeat a number more times.

Using duct tape is a different choice that I haven’t personally tested but that has received excellent recommendations (should you be out of glue.) However, since you’ll have to apply pressure in order to trap the needles, this seems uncomfortable.

In either case, when you remove the spines, make sure to thoroughly cleanse the area with antibacterial soap. You don’t want the injury to contract an infection.

If portion of the needle does not stick out above the skin, you can find it more challenging. You could want to leave it in your skin for a few days if it isn’t hurting you. The needles are pushed to the top by the body, which makes them simpler to catch.

Call an ambulance if you experience a serious fall and become coated in needles, but in reality, it would be best to stay clear of the cacti altogether.
