Does anybody have a good remedy for getting rid of prickly pear? Is there a herbicide that works on it? In Montana I farmed it under or flooded it out with irrigation but neither is an option here. I have been digging it out but parts of the pasture it is so thick I can't walk through it and my horse doesn't like to either! Thanks in advance
 
these ones are cleared, by label.
the paraquats will prob kill everything

I think lots of common 24d types will kill it--but takes a long time.

the 8 or so on bottem of list is what I might try...good luck

But ya gotta get it to stick/absorb. conditioners and surfactants keep getting better---I'd ask a chemical guy what to use for that
 
We had it bad on the south facing slope behind our yard. The pasture had been a big one of 15 sections for 80 years. I fenced off about a section and use it for a calving pasture. After a few years it was in regression. Used to be your dog couldn't run along the side hill now it is mainly grass. Funny thing I was talking to Taylor Brown of Northern Agnet and he said he noticed the same thing on a pasture at his Dad's ranch where the cactus of his youth was almost gone by rest rotation of the pasture.

Paraquat/Gramaxon are both defoliants. They don't care what they defoliate either!!
 
2,4-D will work real good on prickly pear. The trick is to wait for a pretty hot day and around 4 or 5 pm to spray as that is when the stomatas on cactus open up to take in moisture from the air. Perfect timing would be an hour or so before dusk.

And yes, a good grass crop will eventually choke out cactus. Cactus cannot tolerate shade. But a bad infestation of dead cactus will still be hard to graze.
 
I am from an entirely different part of the country but I wonder how a bush hog would work?

In this area if you don't clip a pasture at least twice a year you will have many problems and soon you will not have a productive pasture at all.
 
George,

Never use a bush hog or a drag on prickly pear cactus. It will spread them all over the place as each piece will take root.

Neighbor used a railroad rail for a drag and the result is an unusable pasture.

I spot sprayed mine with a mixture of roundup and 2 4 -d. They are almost history now, but it is hard to get the ones growing in and around scrub oak.

Thanks everyone. I have tried test spraying some of them with 2-4-d and also roundup but never in a mixture. I was spraying thistle so maybe I didn't have it mixed right, also it was early to mid afternoon in July and early August so probably had a lot to to with my timing and that is always critical to success. I just figured this Colorado Cactus was just a lot tougher than MT Cactus! Is there a time of year that works better for spraying cactus than others? I am just east of Denver a little ways and it has been so wet here that the grass is still green. Not a normal year I am sure.
I was told this pasture hasn't been grazed for four years but at one time it must have been severely overgrazed judging from the cheatgrass and cactus infestation.

cowboyup-- not sure on cactus but was reading up on Canadian thistle and some other hard to kill weeds the other day- and North Dakota State University recommended spraying them both in the fall (before a frost) and again in the spring before they go to seed... And then keep hitting whatever spots reappear...
I would think that would work for cactus too...

I just sprayed some patchs of thistle that were starting to spread in a pasture a couple of weeks ago with 2-4-D - and turned them pretty black- but won't know how good I did til spring...
 
I would guess they would be like every thing else. You want to spray when they are actively growing.
I would try late spring, or right after a rain.

Different areas and different results - - - that is why I stated it the way I did - - - Around here we have black locust trees that even if mowed 3 times a year for several years will still be 6' tall and 1" in diameter each time you mow and if left about 3 years you will have a woods instead of a pasture.
