Poison ivy

Soapandbacon · May 21, 2013

I've had enough of poison ivy, oak , sumac ... Until I get a few goats around here , has anyone been successful in eradicating these plants from your property ? If so how? And what are the side effects ? Thanks

I've beat back the poison ivy with relentless use of Roundup. There will be collateral damage, but it's worth it. Be relentless.

Not getting rid of but controlling it. I use this

Shop Roundup 32 Oz. Poison Ivy/Tough Brush Killer Plus Concentrate at Lowes.com

It seems to kill it after a few days. I spray a few times a year around the trees in the yard that had it bad and after a few years I only get a few plants popping up every year. The wood line is covered in a few spots and I would go broke trying to spry that

make up some saltwater and dump it on the poison ivy- kills the plant.

WOW -- $28 for 32 ounces of 1% glyphosate and 0.1% triclopyr.

Young poison ivy can be killed with 2,4D. Add a few drops of Dawn dish soap to cut the surface tension of the ivy for a 1 or 2 gallon sprayer. Only the broadleafs are killed with 2,4D and your grasses will continue growing. Air temperatures typically should be under 85 degrees so the 2,4D does not volatize. As the season goes on and the plants get larger, your options get more limited to glyphosate type products that kill everything that is actively growing. Add a few drops of dish soap or a crop oil to any spray you use on poison ivy to help get the chemical to kill it. Good luck.

Stuff in the link was a concentrate mixing of 12 tablespoons per gallon.

The link says the 32-ounce container will make 5 gallons, so the 12 tablespoons/gallon of water * 0.5 fluid ounces/tablespoon * 5 gallons of water = 30 ounces, close enough.

The recommended application rate of Crossbow (34.4% 2,4-D and 16.5% triclopyr) for poison oak and ivy is 2 fluid ounces per gallon of water (http://www.cdms.net/ldat/ld02H006.pdf.

Crossbow is expensive, +/1 $150 or so for 2.5 gallons (320 ounces), or $0.47/ounce. However, if you have much to spray, Crossbow is a lot less expensive ($4.70/5 gallon mix) than the linked herbicide ($28/5 gallon mix).

Price 41% glyphosphate at Tractor Supply or other farm store. About $30/gallon or $50/2.5 gallon.

My experience is that glyphosate requires multiple applications for control.

Poison ivy and oak don't seem to be able to with stand regular mowing. If all your property is lawn, it probably won't be a problem and for someone who is alergic, making it that way, might be worth it. Unfortunately, part of my lot doesn't lend it's self to mowing. I had to cut a pile of the stuff off a ditch bank with hedge clippers yesterday. The good part is that, it seldom makes me break out.

Stoypoint would I mix that from TS or apply it straight. I have a rather large patch at the woodline I would like to get rid of, but cost has always stopped me .

Salt water works well for me.

The labels for 41% glyphosate say to use 2% of the chemical per gallon of water. This equates to 2.67 ounces of 41% glyphosate per gallon of water. So, if you wanted a 5 gallon mixture, you would add 13.33 ounces of the herbicide to the water. The labels also say "For control. Repeat applications may be required to control. Fall treatments must be applied before leaves lose green color."

At $50 per 2.5 gallons, 41% glyphosate costs $0.16/ounce. Thus, a 5-gallon mix would cost $2.08.

Just in case you get in contact with it, this is what we use. Most drug stores have it, but we get ours at Walmart. It's called Technu. Technu - Poison Ivy, Poison Oak, Poison Sumac Treatment - (www.poisonivy.us)

My experience is also that roundup won't kill it right away, you have to spary it several times.

Sweet, sounds like that is the way to go and much cheaper than the roundup.
