Non-Turf Application

Roadsides (including aprons and guardrails), right-of-way and other similar non-crop areas: For control of broadleaf weeds, mix at a rate of 1.5-3.5 quarts of product per acre. This may require 50-300 gallons of water per acre. For woody plants, apply to both stems and foliage of completely matured plants until they start to go dormant.

Woody brush: Add 1-1.5 gallons of product per acre to wet all parts of the brush foliage, stem and bark. This may require up to 200-600 gallons of water per acre.
