SE MN | Nice video on some greenhouse studies of group 15 rate vs. waterhemp emergence for 4 different waterhemp populations (2 of the populations group 15 resistant, 2 not): https://www.youtube.com/watch?v=dtYvNm_7WGY
Summary of the rates they found to reduce emergence 50% (LD50) for each of the populations can be seen in the LD50.jpg picture attached.
Example of what the emergence looked like for different rates and populations can be seen in the Dual II Magnum.jpg picture attached (similar pictures are in the video for Outlook, Zidua, and Harness).
