Weed Management Is Still Weed Management

LSU AgCenter weed scientist Dr. Donnie Miller says his research with Dual Magnum, Warrant and Outlook Residual herbicides has shown no real difference in weed management.

“Nor did we see a difference in our timing of applications,” says Miller. “We tried to limit our applications to two, where we put the materials down pre-emergence and we followed up later post-emergence with just RoundUp Plus, Xtend A Max or Enlist Duo an Enlist soybeans over the top.”

Miller and his fellow researchers varied where the residual was placed “and we found it did not matter where we put the residual in the system, just as long as we made timely post emergency applications for small weeds. We’re talking 1 to 3 inch weeds that are actively growing.”

“From an injury standpoint, we did not see a difference in injury with either pre-product,” said Miller.
