Ortho GroundClear Poison Ivy & Tough Brush Killer3, 1 gal.

This stuff is serious stuff. It killed my poison ivy within an hour. Other products have taken several days but not this. It also killed deader than a door nail root suckers that kept coming up from a cut down crepe myrtle. If you want something that really works it's this study.

This is easily the most useful product I have bought all year and it has completely transformed my daily routine. The build quality is exceptionally durable, the setup takes less than two minutes, and it functions flawlessly right out of the box. It does exactly what it promises, saving me an immense amount of time and effort every single day while outperforming alternative brands that cost twice as much. Shipping was incredibly fast, the packaging was pristine, and the overall value is unbeatable. If you are on the fence about purchasing this item, just do it—you will not regret it!

This does exactly as it says it will. It killed all of my poison ivy. I started using it for any other weeds as well and it did the job for those also. It’s very simple to use no pumping just opened the nozzle point and spray. It didn’t seem to leak and the battery powered sprayer really makes things easy.

I am not a fan of using herbicides or pesticides, but when it comes to nasty invasive plants it's a challenge controlling them only by weeding. Invasive Asian bittersweet is a big menace around here, and this concentrate can be mixed to an appropriate concentration. For 1" and wider stumps, this 8.8% Brush Killer Plus triclopyr concentrate can be painted on just after cutting the plant. Bittersweet rarely gets that big, but full strength stump painting works for other invasive plants such buckthorn, multiflora rose, barberrry, etc. For bittersweet, I follow a method recommended by extension services, which is to cut it back earlier in the season, and then wait until ~August - September to carefully spray the new growth. Late in the season is when plants are sending more of their sun-produced sugars to their roots, so the herbicide kill is more effective then earlier in the season. I also mix a 1-2% solution (4.5 units of water to each unit of concentrate yields 1.6%), which is stronger than the 0.8% solution found in the ready-to-use version. But you may find the standard dilution to 0.8% effective. Compared to the also-popular glyphosate herbicide, trichlopyr is "selective" in that it does not injure grasses as glyphosate does. But triclhpyr is somewhat more persistent (doesn't break down) in soils. This Brush Killer Plus Concentrate is water-based, low odor, and easy to mix in garden sprayer. I make sure to wear protective clothing- Tyvek suit, old boots, heavy duty water gloves, and eye protection. Important to spray on a relatively calm day with no rain expected in the near future. Great to see areas that were once infested in 95% bittersweet showing a variety of native plants the next season. That is the ultimate goal: native plants that are good pollinators for insects and other animals.

It rained 6 hours after initial application (naturally). the next morning some wilting was evident. After a second application a day later, there is visable browning and wilting. Seems to be effective. The electric sprayer works better than expected. A nice touch if you have weak hands.

Works great just takes a little longer than advertised

After three days there is some yellowing on plants but has not killed them yet. Disappointed because the price is high for not doing much. The sprayer works great and comes out fast but other than that it’s a waste of money. Edit after a week some of the plants are browning up and dying. Looks like a lot of the poison ivy is dying also now. Let’s hope it just took some time.

This worked great. It killed everything it needed to and the poison ivy is gone for now. It did kill some grass, but I don't care. It didn't hurt the yucca plants or the trees. The sprayer was awesome and I was so glad I didn't have to mess with my sprayer or mix anything. I gloved and masked up. There is a lingering smell for a couple of days but not terrible. Highly recommend.
