                                   For applications to corn, tankmixing with atrazine may enhance weed control of this species.
                                   May require sequential applications for control of populations of weeds with mixed heights.
                                   For best control, do not apply before weeds reach 6 inches tall.

                      “Liberty herbicide came along as we started to see resistance
                       to different weeds. The bottom line is we have to protect it.
                      We need to include it as a part of the best program that we
                     put together. You just can’t have one thing or one
                    direction for everything – you have to mix it up.”
