Looking for soybean fields with late season waterhemp

Common waterhemp true leaves without singular hair in the leaf tip notch

OSU weed scientists and ag engineers are looking for soybean fields that have populations of waterhemp or Palmer amaranth surviving into July and August (after all control with herbicides has been attempted).  We have a project involving the use of a drone to identify these weeds in mid to late season when they are evident above the soybean canopy.  We need fields with more than just a few surviving plants.  Populations consisting of a few good patches up though a disaster are fine.  Contact Mark Loux – loux.1@osu.edu, 614-395-2440.  Thanks in advance for your help.
