Bonide Poison Oak & Ivy Killer, 32 oz Ready-to-Use Spray for Home Gardening, Fast-Acting Formula Kills the Roots

I had good results with this. I used it on blackberry, smilix, poison oak and ivy, plus your general stubborn southern weeds

Used this last season to kill some poison ivy that survived some heavy doses of brush killer. Everything sprayed last year didn’t come back this year. Super happy with the results

This seems to work killing poison ivy but it took three to four applications to se results

This product is wonderful. It works almost immediately. No offensive odor.

This is an important review because the listing does not make it clear that it is a slow acting control. It took 2 weeks after application before I saw ANY affect. By the third week, there was definite wilting of the mature plants. After a month, the only thing left were the dead leaves. Of course, you will still need to be careful not to touch the dead plants.It is important to caution any buyers to just apply and forget about it. This control formula will eventually do the job. I believe that because it is slow acting, it will cause less damage to other plants. And it may cause some buyers to just return it to AMAZON. That would be a mistake. There was still some damage to a neighboring bush where the solution hit it but not enough to hurt the bush. If you want to protect other plantings, I recommend using a piece of cardboard to protect other plants.

Bottle was leaking in box

I purchased this locally for poison ivy in May, and it worked well. You only apply it just once to foliage and it gradually kills the roots. At first, it doesn't seem like it is doing much, but the plants died back over the course of days to a week after the one application. I haven't noticed any effects to adjacent, non-target plants. Nearby, I had a small stand of Japanese knotweed that I was quite worried about and planning to try to cover for years to smother (since there are few other options for this pernicious weed). Japanese knotweed is not indicated on the label, but I tried it anyway. I am thrilled and amazed to see that it has worked--a month later, the plants have died back and there has been no new growth since. I then tried on Oriental bittersweet (another terrible invasive) and it worked on that as well even thought it is not on the label either. I am so impressed that it has worked on the knotweed especially--this seems like a game changer in the fight against some of our worst invasives.

Squirt bottle leaked all over my hands while pumping trigger. had gloves on but totally wasted product. ended up throwing spray head away and just poured the stuff on the roots of the poison ivy. day two haven't even seen wilted leaves yet.
