Will kill most vegitation

Visual proof is always good. It does kill those difficult viney weeds. Straight strength will slowly kill a tree, poured a the tree base. Good Stuff

Good spray feature

Would Recommend

I have yet to see how effective it is, but I love the battery-powered spray. Last year I had to squeeze spray and it was tougher to cover a big area.

Not great value

Would Not Recommend

I bought this product to kill saplings that shot up from roots of trees I had cut down. It took 4 applications and there were still green leaves on about 20 percent of what I sprayed. It did kill poison ivy with a single application.
