DuPont herbicides for
land management
Introducing three herbicides to help land managers achieve safer sites
and greater productivity
DuPont herbicides for
land management Proprietary Active Ingredient
• Products built around aminocyclopyrachlor, a proprietary active ingredient from DuPont
• Pyrimidine carboxylic acid class • New generation of synthetic auxin herbicides • Unique properties at molecular and whole-plant
levels deliver more potent herbicidal activity than other active ingredients – Faster action – Control wider spectrum of
broadleaf weeds, brush
DuPont herbicides for
land management New Chemistry Features
• Excellent post-emergence control of many broadleaf, briar, vine and brush species
• Excellent residual control of many difficult-to-control broadleaf weeds
• Dry, concentrated formulation for less handling • Comparatively low use rates per acre • Favorable environmental profile for minimal
impact on the environment • Low toxicity to mammals, birds and fish
DuPont herbicides for
land management Biological Activity
• Quickly taken up by leaves, stems, roots • Effects within a few hours to a few days
– First: Bending, twisting of stems and leaves – Advanced: Severe necrosis, stem thickening, growth
stunting, leaf crinkling, calloused stems and leaf veins, leaf-cupping, enlarged roots
• Death of treated broadleaf weeds may require several weeks
• Death of treated woody plant species may require several months

– Tank mix a contact herbicide such as Roundup Pro for control of
existing vegetation on site at the time of application *Preferred treatments for Pigweed control (add additional grass product to the mix when appropriate)
