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

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

I have used this product to kill poison ivy that is new and relatively low growth and also some that has climbed trees up to heights of up to 20 feet. It does show effect overnight as advertised, but has not fully killed the ivy for some time (weeks) afterwards. On large ivy vines, I spray all the leaves that the sprayer can reach (maybe 8 feet) and trust that it will go downward and kill the root. It seems to work, but takes time. In several cases, this may be a month or more. It is not as specific as I had hoped, but that has a good side - it also will kill wild raspberry bushes, multi-flora rose and other weed species. Be careful with over-spray and this should not be a major problem. Using the sprayer setting rather than misting, it is easy to control where the spray goes and die back of desirable plants is minimal. I've bought this product repeatedly because I treat a lot of area where ivy has been allowed to grow, and it has always produced reliable results. I am very pleased with this product - I just wish I could buy a gallon size to use in my backpack sprayer!

I’ve used this mainly on small poison ivy sprouts, but it does kill them if used per the instructions. After liberally spraying the plant, it was wilted the next day and completely dead two or three days later. It also killed a Virginia creeper vine I sprayed it on. Only bad thing is it can be a gamble buying things like this from Amazon because my bottle had leaked some at some point during shipping. Also, either the bottle leaks while spraying or the mist can blow back on the bottle and your hand while using, so make sure to wear gloves while you use it. Other than that, the stuff actually does work.

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.

My neighbor's poison ivy is growing into my yard, so I needed a way to stop it. This does a good job of killing just the ivy, but not other plants. Beware of applying with wind. It also took out ground ivy too. Yay!

Bottle was leaking in box

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.

It came leaking all over the inside of the wrapper. I spent 10 minutes requesting a replacement since you have to keep entering 500 words in several places for it to proceed and the replacement was leaking all over the inside of the wrapper as well
