A website from UGA Cooperative Extension

The following information came from Dr. Erik Prostko, UGA Weed Science Specialist

A few things to chew on: 

1) I have gotten many questions about tank-mixing Roundup + Liberty for weed control in field corn.  Check out this picture from my 2024 plots (May 6).  No real difference in weed control between 22 oz/A or 27 oz/A or 32 oz/A of Roundup + Liberty (tank-mixed with Atrazine and Prowl).  Field corn looks a little ratty because the farm received 0.9″ of rain on May 4 and some hail.

2) Justin Hand (Tift Co. Agent) and I just got back from trying to help a grower figure out a tank-mixing problem he was having with NIS + diuron + fomesafen + paraquat.  Turns out that the problem was related to the diuron formulation.  No problems with the Direx (Adama) formulation (left) but a significant problem with the Diuron (Drexel) formulation (right). 

This information is being relayed from Dr. Prostko. For more information please call your county extension agent at 1-800-askuga1 or Burke County Extension at 706-554-2119
