We have passed several fields where the soybeans have emerged, but the field did not receive a burndown herbicide (see accompanying photo). Weeds like dandelion, resistant marestail/horseweed, etc. will be very difficult to control postemergence in soybean. Also, many of the typical soil applied residual soybean herbicides cannot be applied over the top of soybeans because of injury concerns. Below is a list of herbicides that have foliar broadleaf activity and/or residual activity and are allowed POST along with their labeled application timings and strengths. Unfortunately, most of these herbicides will not handle dandelion, burdock, curly dock, etc. very well. This is not a comprehensive list and excludes generic products and herbicides that are mostly active on grasses and/or not typically applied POST.
Thank you for your submission!
