So have noticed something this summer while spraying beans, wit the wet spring we had we fixed a lot of tile and added more in some spots. Where we added it got disced level afterwards, fixed spots just got graded off level, either way had bare dirt.
When spraying burndown for beans we use Resist (generic Canopy) and 2-4d, when spraying RU now of cleanup have noticed the spots that were bare when spraying burndown are as clean as a whistle while where we had cover crop its like we never sprayed a residual. Can the cover crop tie the residual up so it never makes it to the ground? This is really apparent in the last few fields we sprayed burndown on that had a two foot tall cover crop. If so what is the workaround? The clean spots are also void of any mares tail as well.
