We seem to have less pigweed issues after we lime.
Thunder or raptor, raptor is more $$$, but has a 14 day phi instead of 30, and seems to have more activity on broadleaves, but less residual.
If you think you can time it right you could run 2 pints or so of treflan with it, but it needs .5 in of rain to incorporate. I think prowl h20 has like a 50 day phi.
Generally here once a stand thins enough to get weedy, the yield is dropping anyway, the only time we try to stretch a stand to 5 years is on the sand where it is tough to get a good stand, and it takes 2 years to get to full production.
