Covering The Residual Gap

Saw an ISU presentation by Dr. Bob Hartzler in which he said there was a problem between when the pre-emergence residual wore out and when the post-ermergence could kick in.  


His solution was to reapply a pre-emergence with residual just before crop emergence.


His bottom line was the old days of hoping for a one-pass or maybe even a two-pass herbicide system were done.
