Message in a Bottle: Season-Long Container Weed Control

Jan 23 2017 - 3:00pm

In the spring of 2015, the oldest message in a bottle was found, 108 years and 138 days after being dropped into the North Sea.  It reminds me some research questions take a long time to answers.  Sometimes the delay is because we are not asking the right questions.  We usually research herbicides as individual applications; however, we apply herbicides in consecutive applications.  We are told to rotate modes of action (MoA), but what is the effect of one herbicide following another on the crop and on weed control.  These and other questions will be answered in this talk, based on new research conducted in 2015-2016.
