I run 1qt remedy and 1 qt 2,4-d mixed together in 100 gals of water with 1-2 pints of 80/20 surfactant added to the final 25 gals. Looking at it again yesterday, after spraying a month ago I got about 85% kill on goatweed. 60-maybe 70% on tallow, and maybe 40% kill on blackberry and 50% on gum. Hard to tell with sweetgum--it takes a long time for it to actually die.
I saw no nettle when spraying, but have had some come up since then, and I know now, I missed a lot while spraying slopes. Spraying slopes changes the geometry of a boomless nozzle pattern. Overshoot some places, and get a narrow wet swath on the opposite side.
I will be spot spraying nettle 50/50 remedy to water and the spraying the same 60 acres again in late Sept with the same 1 qt/100 gal water mix ratio I used in late May.
