General Information


TRIQUAD is a herbicide used to control unwanted woody plants and annual and perennial broadleaf weeds.

- in forests;

- on permanent grass pastures, rangelands, and conservation reserve program (CRP) acres (including non-irrigation ditch banks and fence rows within these areas);

- on non-crop areas including industrial manufacturing and storage sites;

- on rights-of-way such as electrical power lines, communication lines, pipelines, roadsides, and railroads;

- on fence rows;

- on non-irrigation ditch banks;

- around farm buildings;

- on perennial bluegrass, perennial ryegrass, and tall fescue ornamental turf (including sod farms, commercial turf, and golf courses).

TRIQUAD use on these sites may include application to grazed areas as well as for the establishment and maintenance of wildlife openings.


- Agricultural Use Requirements for Forestry Uses: For use of this product on forestry sites, follow the Personal Protective Equipment (PPE) and Re-entry Interval (REI) restrictions in the AGRICULTURAL USE

REQUIREMENTS section of the label.

- Use Requirements for Non-Cropland Areas: No Worker Protection Standard worker entry restrictions or worker notification requirements apply when this product is applied to non-cropland.

- In Arizona: The state of Arizona has not approved TRIQUAD for use on plants grown for commercial production; specifically on designated grazing areas or for use on sod farms.

- Local conditions may affect the use of herbicides. Consult your local specialist for advice in selecting treatments from the label to best fit local conditions.

- TRIQUAD may injure certain turfgrass species. Do not apply to bahiagrass, bentgrass, bermudagrass, centipedegrass, St. Augustine grass, or zoysiagrass, unless turf injury can be tolerated.

- Do not apply TRIQUAD to exposed roots of shallow rooted trees and shrubs.

- Do not apply TRIQUAD to golf course greens.

- Do not apply more than 2 quarts of TRIQUAD per acre in a single application when spot treating.

- Do not apply this product through any type of irrigation system.

- Do not apply to ditches used to transport irrigation water. Do not apply where runoff or irrigation water may flow onto agricultural land as injury to crops may result.

- It is permissible to treat non-irrigation ditch banks, seasonably dry wetlands, flood plains, deltas, marshes, swamps, bogs and transitional areas between upland and lowland sites. Do not apply to open water such as lakes, reservoirs, rivers, streams, creeks, salt water bays, or estuaries.

- Do not apply this product through mist blowers unless a drift control additive, high viscosity inverting system, or equivalent is used to control spray drift.

- Avoid direct application to Christmas trees as conifer injury may result. When treating unwanted vegetation in Christmas tree plantations, use sprays directed away from conifers.

- Do not make direct applications of TRIQUAD or allow spray mists containing TRIQUAD to drift onto cotton, fruit or orchard trees, shrubs, grapes, peanuts, soybeans, tobacco, vegetable crops, flowers, citrus, or other desirable broadleaf plants.

- Many forbs (herbaceous broadleafs) are susceptible to TRIQUAD. Unless injury or loss of such plants can be tolerated, do not spray pastures containing desirable broadleaf forbs (especially legumes such as clover). After applications, the stand and growth of established grasses is usually improved, however, especially when rainfall is adequate and grazing is deferred.

- While established grasses are tolerant to this product, newly seeded grasses may be injured until well established (as indicated by vigorous growth, tillering and the development of a secondary root system).

Do not reseed treated areas for a minimum of three weeks after treatment.

- While TRIQUAD is formulated as a low volatile ester, the combination of spray contact with impervious surfaces (such as roads and rocks) and increasing ambient air temperatures may result in an increase in the volatility potential for this herbicide, increasing a risk for off-target injury to sensitive crops such as grapes and tomatoes.

- Use of this product in certain portions of California, Oregon, and Washington is subject to the January 22, 2004 Order for injunctive relief in Washington Toxics Coalition, et. al. v. EP C01-0132C, (W.D. WA). For further information, please refer to

- Portions of grazed areas that intersect treated non-cropland, rights-of-way, and forestry sites may be treated at up to 8 lbs. ae per acre if the area to be treated on the day of application comprises no more than 10% of the total grazable area.

- On use sites other than grazable areas and forestry sites, do not apply more than 8 lbs. a.i. per acre per year of triclopyr (8 qts. per acre per year of TRIQUAD).

- On use sites that may be grazed, including rights-of-way, pasture, fence rows, and rangeland, do not apply more than 2 lbs. active ingredient per acre per year of triclopyr (2 quarts per acre per year of TRIQUAD).

- On forestry use sites, do not apply more than 6 lbs. active ingredient per acre per year of triclopyr (6 quarts per acre per year of TRIQUAD).


Except for lactating dairy animals, there are no grazing restrictions following application of this product.

- Grazing Lactating Dairy Animals: Do not allow lactating dairy animals to graze treated areas until the next growing season following application of this product.

- Do not harvest hay for 14 days after application.

Slaughter Restrictions:

Withdraw livestock from grazing treated grass or consumption of treated hay at least 3 days before slaughter. This restriction applies to grazing during the season following treatment or hay harvested during the season following treatment.


Water Dilutions

To provide improved wetting of foliage using water dilutions, an agricultural surfactant at the manufacturer’s recommended rate may be added to the spray mixture. To help minimize spray drift, a drift control and deposition aid cleared for application to growing crops is recommended.


Avoid drift. Very small quantities of spray may seriously injure susceptible plants. Do not spray when wind is blowing toward susceptible desirable vegetation. The applicator may detect the potential for drift by producing smoke at or near the spray site and observing for a temperature inversion or for potential of off-site movement.

If the smoke layers or indicates a potential of hazardous spray drift, do not spray.

Broadcast Applications

TRIQUAD may be applied aerially by fixed wing aircraft or helicopter to rangeland, permanent grass pastures, and conservation reserve program acres. For all other use sites listed on the label, TRIQUAD may only be applied aerially by helicopter.

For aerial application to rangeland, permanent grass pastures, and conservation reserve program acres:

Air (Fixed wing aircraft or Helicopter)-For aerial applications to rangeland, permanent grass pastures, and conservation reserve program acres, apply TRIQUAD through a Microfoil or Thru-Valve boom, or use an agriculturally labeled drift control additive. Do not use a thickening agent with the Microfoil or Thru-Valve booms, or other systems that cannot accommodate thick sprays. Keep spray pressures low enough to provide coarse spray droplets and spray only when the wind velocity is low (follow state regulations). Avoid application during air inversions.

Air (Helicopter Only)-When making aerial applications on rights-of-way or other areas near susceptible crops, efforts should be made to minimize drift. Applications should be made with nozzles and pressures which provide adequate plant coverage, but minimize the production of fine spray particles. Drift can be minimized by applying through the Microfoil boom or Thru-Valve boom. Drift control agents or high viscosity invert systems can also be used to minimize drift. Do not use the high viscosity invert system unless it is as effective as the booms listed or as effective as available drift control agents. Use of low pressure nozzles and operating these nozzles in the lower end of the manufacturer’s recommendations is advised. To minimize drift, use a spray boom that is no longer than 3/4 the rotor length, spray when wind velocities are low, or by using an approved drift control system.

Such reference by MANA is not intended as an endorsement of such equipment, shall not constitute a warranty (express or implied) of such equipment, and is not intended to imply that other equipment is not available and equally suitable. Any discussion of methods of use of such equipment does not imply that the reader should use the equipment other than is advised in directions available from the equipment’s manufacturer. The reader is responsible for exercising their own judgment and expertise, or consulting with sources other than MANA, in selecting and determining how to use its equipment.

Ground: Applications should be made with nozzles and pressures which provide adequate plant coverage, but minimize the production of fine spray particles. Large droplet producing equipment, such as the Radiarc sprayer may aid in reducing off-target drift. Drift control agents or high viscosity invert systems can also be used to minimize drift. Use of low pressure nozzles and operating these nozzles in the lower end of the manufacturer’s specified rates is advised. To minimize drift, keep the spray boom as low as possible; apply in = 20 gallons of spray volume per acre; spray when wind velocities are low; or use an approved drift control agent.

High Volume Leaf-Stem Treatments: Make applications no higher than brush tops with low pressure and coarse spray droplets to minimize spray drift. A drift control agent may be used to reduce spray drift.

Refer in the label regarding tank mix information.

Limitations, Restrictions, and Exceptions

Aerial Application (Helicopter Only)-Aerial sprays should be applied using suitable drift control. See the SPRAY ADDITIVES and the APPLICATION EQUIPMENT AND TECHNIQUES section.

Basal Bark and Dormant Brush Treatments

To control woody plants in rights-of-way, in other non-crop areas, forests, rangeland and permanent grass pastures; use TRIQUAD in oil or oil-water mixtures prepared and applied as described in the “Mixing Directions - Oil Mixture Sprays for Basal Treatment” section of the label. Do not graze treated areas following use of oil or oil-water mixtures. For non-foliar applications on rangeland and permanent grass pastures, apply no more than 2 quarts of TRIQUAD (2 lb. ae of triclopyr) per acre per year.
