Trillion, par-3, premium 3way and I believe target are all basically the same thing. Estaprop, dicamba and a phenoxy (don't recall which one). They all work great with high water volumes for "crop safety". I use trillion because it's the cheapest but I also use rinsate from my sprayer if I spray a broadleaf only and rinse at home. I have a 6 acre patch of "lawn" out back and will spray the rinsate out there. I also have a jug of Grazon that I use but not near my trees.
