I only use this brand to kill all the poison ivy, oak and all in its family. It kills it no doubt

Works great

Works as stated. No leaks on arrival

Using the wand makes it easier to use on green briar which has leafed out as well as ivy. I have been told to be careful if using on nuisance ivy which is trying to take over good plants, but a little bit of product is not going to systemically take out the the good woody plant. But I still try to gently pull the ivy off and lay it on the ground and spray the ivy leaves and watch it slowly take out the plant over the next week or two.

We are constantly fighting blackberries and this seems to be the only product that fazes them. It does an outstanding job on tansy, dandelions, foxglove and broad leaf weeds. It doesn't do too well on small tree suckers, just disables them a bit then they return. Be careful not to get this on your skin. It is powerful stuff.

Black berries, I can hit some black berry plants and they look dead the next day. Some look like they were stunned but not out and others look at me like, is that the best you got! I find myself spraying some black berry bushes 2 to 5 times. I also mix more than recommended to try to over power but the results are the same. I’ve gone through many bottles this year and still fighting pop ups and resisters! I encourage round up to test their products on the plants in my yard!

I used this on a few patches of poison ivy. It took a couple applications and some time, but it did the job.
