Controls Tough-To-Kill Broadleaf Weeds as part of an Integrated Weed Management Program

A selective herbicide with an underutilized mode of action, TOUGH® 5EC provides post-emergence control of actively growing broadleaf weeds.
In 2017, Dr. Rick Boydston, USDA ARS, coordinated research trials at five locations, representing the major U.S. mint production regions. These trials compared the effectiveness of pyridate, the active ingredient in TOUGH 5EC, to other broadleaf herbicides currently registered in peppermint, native spearmint or Scotch spearmint.
As you can see in the photos on the left from these Washington field trials, it was observed that TOUGH 5EC was the most effective herbicide treatment at all locations and never lowered mint oil yields.1
TOUGH 5EC is especially effective on Kochia, Pigweeds, Palmer Amaranth, Waterhemp, Common Lambsquarters, and Black Nightshades. It is even effective on strains resistant to other more-commonly used herbicides.
