Most of our bean burndown had Invive added to it for some residual and I think it helped with the burndown, only thing I'm seeing not dying down 100% is some 3-4' tall mairstail.  Instead of AMS we are using some 32% with the water and on some of the weedier fields I bumped it up to 2 gpa of 32% which I think also helped kill the weeds.  Had a couple of no-till corn fields that were pretty wild but we put down 10 gpa of 32% as the carrier along with 40oz of Abundant and some Corvous and that stuff was down to almost bare ground in 10 days.
