Gly with triclopyr will do what you want, for the most part. Most brush guys will spray 3% glyphosate in their mixes. You can go lower, but may not be as consistent. You can go about 0.5-1.0% on the triclopyr and be ok. If it goes out too "hot" it can shut a plant down and minimize the translocation of something like glyphosate. If you have sweetgums this may not kill them if they are too large. Add an MSO or crop oil for best results. It is also best to spray briars in the late summer for better kill, provided they aren't drought-stressed.


If you do the things you need to do when you need to do them then someday you can do the things you want to do when you want to do them.
