I've been using Triclopyr on the poison oak on my land. I found that the recommended concentration in homeowner product was all over the map. I ended up finding a document on PO control from the University of California at Davis (big ag school) summarizing results of studies and listing actual percentage concentations they recommend. From that I calculated that the homeowner stuff was too weak. I don't want to spray more herbicide than I need but I also don't want to suit up and crawl through poison oak more times than I have to.
I bought some serious Triclopyr (64% vs 8% in Brush B Gone) and mixed my own with surfactant. It's much more effective even at the lowest concentration in the UCD document.. which is about 8x the "strong" concentration on the label of Brush B Gone.
