Product Overview

PastureGard HL is a highly effective herbicide that controls unwanted weeds and woody plants. Contains two active ingredients that powerfully eliminates undesirable broadleaf weeds and brush. It is ideal to apply in permanent pastures, rangelands, fence rows, CRP acres, non-crop areas like around farm buildings, and non-irrigation ditch banks. The PastureGard HL is specially formulated as an oil-soluble, emulsifiable liquid that may be mixed with water or with oil. It helps in protecting and improving grazing acres by removing weeds and making way for better utilization of the land. It controls broadleaf weeds and woody plants such as aspen, elderberry, dogwood, bedstraw, burdock, chickweed, clover, curly dock, and morning glory. May be applied through foliar, broadcast, cut stump, or basal bark application. For plants that are in full leaf, it is highly recommended to apply the herbicide through a direct foliar spray or broadcast application.

Broadcast Directions

Woody Plant Control: Apply PastureGard HL when conditions are favorable for active growth, but only after leaves are fully expanded and terminal growth has slowed. Application to immature foliage during periods of rapid terminal growth will result in rapid defoliation, but translocation of the herbicide and woody plant control may be reduced. If brush has been mowed, best results are obtained when at least 9 - 12 months of regrowth following mowing is allowed before herbicide application (12 months is recommended in areas where growing conditions such as low rainfall have limited brush regrowth following mowing). Adequate soil moisture before and after treatment as well as healthy foliage at the time of application is important for optimal effectiveness. PastureGard HL will control only broadleaf plants that are emerged at the time of application.

Apply at the specified rate (1.5 – 4 pints per acre, unless otherwise specified) in 4 or more gallons of water per acre by air or 10 or more gallons per acre by ground equipment. Use higher spray volumes to ensure adequate foliar coverage where brush canopy is dense. If applied in the tank mix, follow applicable use directions, precautions and limitations on the respective labels (see instructions for tank mixing under Mixing Directions). The optimal rate of PastureGard HL will depend on brush size as well as the species. For smaller brush (less than about 6 feet tall), 1.5 – 2 pints/acre will be sufficient. For larger brush and mixed brush canopies, apply 2 - 4 pints/acre.

Surfactant A nonionic surfactant or liquid fertilizer at 1-2 quarts per 100 gallons spray solution (0.25% – 0.5% v/v) may improve weed control for either broadcast or spot application, especially if plants are drought-stressed. To help minimize spray drift, drift control and deposition aid cleared for application to growing crops are also recommended.

Rates for Specific Woody Plants:

  • Ash
    • 1.5 - 4 pt/acre
    • Active growth
  • Blackberry
    • 1.5 - 4 pt/acre
    • Apply when leaves are fully expanded and the foliage is dark green, either before the first flower or after fruit drop. Application after fruit drop is preferred. Do not treat blackberries in the same year after mowing, shredding, or burning. Even one year after removal of top growth, blackberry stands will be more difficult to control than undisturbed stands and will require retreatment.
  • Elm
    • 1.5 - 4 pt/acre
    • Apply late spring through summer to mature foliage
  • Flame sumac
    • 1.5 - 4 pt/acre
    • Apply late spring through summer to mature foliage
  • Hawthorn
    • 1 - 4 pt/acre
    • Apply late spring through summer to mature foliage
  • Honeylocust
    • 1.5 - 4 pt/acre
    • Apply spring through summer to mature foliage
  • Honeysuckle
    • 1.5 - 4 pt/acre
    • Apply late spring through summer to mature foliage

  • Persimmon
    • 1.5 - 4 pt/acre
    • Apply late summer through fall under good growing conditions
  • Poplar, Prickly ash, Sumac
    • 1.5 - 4 pt/acre
    • Apply late spring through summer to mature foliage
  • Wax Myrtle, Willow
    • 1 - 4 pt/acre
    • Apply late spring through summer to mature foliage

Maximum Application Rate: Do not apply more than 0.5 lb ae Fluroxypyr or 1.5 lb ae triclopyr (2 quarts per acre of PastureGard HL) per annual growing season.

Specific Use Directions

When difficult to control species such as ash, choke cherry, elm, maple or oaks are prevalent, in late season when plant foliage is mature, or when growing conditions are less favorable, use the higher rate in rate range. PastureGard HL may be tank mixed with other herbicides such as Grazon P+D specialty herbicide or Tordon 22K specialty herbicide to control additional woody species listed on their respective labels.

Shinnery Oak Suppression: Apply PastureGard HL as a broadcast application at 2 pints per acre for suppression of shinnery oak growing on sandy soils.

Oaks, Post Oak, and Blackjack Oak - Regrowth Stands: Apply in the late spring (May) to early summer(June) when oak leaves are fully developed (expanded). Use 5 or more gallons of spray solution per acre by air and 15 to 25 gallons per acre by ground equipment. Lower spray volumes and rates may be used for suppression only. Control will require 2 or more applications.

Apply when musk thistles or other biennial species are in the seedling to rosette stage and before flower stalks appear. Refer to the Weeds Controlled section for a listing of susceptible weed species and weeds that may be only partially controlled and require repeat applications and/or use of higher specified rates, even under ideal conditions of application.

  • Broadcast: Annual broadleaf weeds - 0.75 - 1 pt/acre
  • Broadcast: Biennial and perennial broadleaf weeds - 1 – 1.5 pt/acre
  • Spot (Small Area) Treatment: broadleaf weeds - Apply at a rate comparable to quot;broadcast"

Mixing Directions

PastureGard HL will readily mix with oil or can be mixed with water to form an emulsion. For water mixtures, an agricultural surfactant at the manufacturer's recommended rate may be added to the spray mixture to provide improved wetting of foliage. For foliar applications, a drift control and deposition aid cleared for application to growing crops are recommended.

Water Dilutions: A water-based spray solution is recommended for broadcast and high volume foliar. Add PastureGard HL to 3/4 of the required amount of water and while agitating bring the spray mixture to the required volume. Add any surfactants or drift control agents to the mixture only after adding PastureGard HL. A nonionic surfactant or liquid fertilizer at 1-2 quarts per 100 gallons spray solution (0.25% – 0.5% v/v) may improve weed control for either broadcast or spot application, especially if plants are drought-stressed. To help minimize spray drift, drift control and deposition aid cleared for application to growing crops is also recommended.

Oil Mixture Sprays for Basal Treatment: When preparing oil-based spray mixtures, use either diesel fuel, No. 1 or No. 2 fuel oil, kerosene or a commercially available basal oil. Substitute other oils or diluents only as recommended by the oil or diluent's manufacturer. When mixing with a basal oil or other oils or diluents, read and follow the use directions and precautions on the manufacturer's product label. Add PastureGard HL to the required amount of oil in the spray tank or mixing tank and mix thoroughly. If the mixture stands over 4 hours, re-agitation is required.

Tank Mixing

It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.
