General Information


Lineage Clearstand Herbicide is a dispersible granule that is mixed in water and applied as a spray by ground or aerial application.

Lineage Clearstand Herbicide is labeled for the control of annual and perennial weeds and unwanted woody plants on conifer plantations (release), private, public and military lands, on rights-of-way, industrial sites, non-agricultural areas, rangeland, pasture, wildlife management areas, ditch banks of dry drainage ditches, and certain types of unimproved turf grass, including grazed areas on these sites. It may also be used to control weeds along the banks of drainage canals or ditches. Only treat up to the outer edge of a drainage ditch or canal when it contains water. Do not apply Lineage Clearstand Herbicide on irrigation ditches or canals. Do not apply Lineage Clearstand Herbicide on dry irrigation canals or dry irrigation ditches.

Lineage Clearstand Herbicide may be applied on conifer plantations, wildlife management areas, rangeland and pasture and non-agricultural areas that contain areas of temporary surface water caused by the collection of water between planting beds, in equipment ruts, or in other depressions created by management activities in these sites, except in the states of California and New York. It is permissible to treat drainage ditches, intermittent drainage sites, intermittently flooded low lying sites, seasonally dry flood plains, and transitional areas between upland and low land sites when no water is present, except in the states of California and New York. It is also permissible to treat marshes, swamps, and bogs after water has receded, as well as seasonally dry flood deltas, except in the states of California and New York.

Lineage Clearstand Herbicide may be applied by ground spray equipment (boom sprayers, backpack sprayers, tree injection, etc.). Lineage Clearstand Herbicide may also be applied by aerial spray equipment.

Aerial equipment designed to minimize spray drift, such as a Helicopter equipped with a “Microfoil” boom, “Thru-Valve” boom or raindrop nozzles, must be used. Except when applying with a “Microfoil” boom, a drift control agent may be added at the specified rate.

Lineage Clearstand Herbicide controls weeds and woody plants primarily by postemergent activity. Although Lineage Clearstand Herbicide has preemergence activity, best results are generally obtained when Lineage Clearstand Herbicide is applied to foliage after emergence or dormancy break. Generally, for the control of annual weeds, Lineage Clearstand Herbicide provides the best results when applied to young, actively growing weeds. For the control of perennial weeds, applications made at the bud/bloom stage or while the target weeds are in the fall rosette stage may provide the best results. The use rate depends upon the weed species and size at the time of application. The degree and duration of control may depend on the following:
- weed spectrum and infestation intensity
- weed size at application
- environmental conditions at and following treatment
- soil pH, soil moisture, and soil organic matter.

Good spray coverage of the target plant is desired. Excessive wetting which causes the spray to run off target plants must be avoided.

Note: Injury or loss of desirable trees or other plants may result if Lineage Clearstand Herbicide is applied on or near desirable trees or other plants, on areas where their roots extend, or in locations where the treated soil may be washed or moved into contact with their roots.

Applying or draining or flushing equipment on or near sensitive desirable plants, or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots may cause severe injury or death to these plants. Do not treat irrigation ditches, or water used for crop irrigation or for domestic uses.


Lineage Clearstand Herbicide is quickly taken up by the leaves, stems and roots of plants with accumulations occurring in the growing points of the plant. Growth of treated plants stops soon after treatment. Within one to three weeks after application, the leaves begin to turn yellow (chlorosis) and then gradually become necrotic. Death of the plants may require several more weeks. Lineage Clearstand Herbicide is rain-fast at one hour after application.


For best performance, include a spray adjuvant when making postemergence applications of Lineage Clearstand Herbicide. Non-ionic Surfactants: Use a non-ionic surfactant at a minimum rate of 0.25% v/v (1 quart surfactant per 100 gallons of spray solution). Surfactant products must contain at least 70% non-ionic surfactant with a hydrophilic/lipophilic balance (HLB) of 12 to 17.

Methylated Seed Oils or Vegetable Oils: Under temperature or moisture stress conditions, a methylated seed oil (MSO) or vegetable oil based adjuvant may provide increased leaf absorption of Lineage Clearstand Herbicide. For spray volumes of less than 30 gallons per acre use a rate of 1.5 to 2 pints per acre. For higher volume applications, spray volumes greater than 30 gallons per acre, include the MSO or vegetable oil adjuvant at 1% v/v (1 gallon per 100 gallons of spray solution).

Silicone Based Surfactants: Silicone based adjuvants reduce the surface tension of the spray droplet allowing better coverage of the leaf surface compared to some nonionic surfactants. In some cases, the silicone adjuvant may dry too quickly limiting uptake. Refer to the manufacturers instructions for use rates.

Invert Emulsions: Lineage Clearstand Herbicide may be applied as an invert emulsion. The spray solution results in an invert (waterin-oil) spray emulsion designed to minimize spray drift and spray run-off, resulting in more herbicide on the target foliage. The spray emulsion may be formed in a single tank (batch mixing) or injected (in-line mixing). Consult the invert chemical label for proper mixing directions.

Ammonium Nitrogen Fertilizer: In addition to a non-ionic surfactant or seed oil concentrate, ammonium nitrogen fertilizer may be added to the Lineage Clearstand Herbicide spray solution. Use 32 to 48 ounces per acre of a high-quality urea ammonium nitrate (UAN), such as 28% N or 32% N, or a spray-grade ammonium sulfate (AMS).


When herbicides that affect the same biological site of action are used repeatedly over several years to control the same weed species in the same field, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that field. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different site of action. To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tankmix partners and/or sequential herbicide applications that have a different site of action. Weed escapes that are allowed to go to seed will promote the spread of resistant biotypes. It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative for specific alternative cultural practices or herbicide recommendations available in your area.


This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area.


This product may be considered for use on public, private, and tribal lands to treat certain weed species infestations that have been determined to be invasive, consistent with the Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) National Early Detection and Rapid Response (EDRR) System for invasive plants. Effective EDRR systems address invasions by eradicating the invader where possible, and controlling them when the invasive species is too established to be feasibly eradicated. Once an EDRR assessment has been completed and action is recommended, a Rapid Response needs to be taken to quickly contain, deny reproduction, and if possible eliminate the invader. Consult your appropriate state extension service, forest service, or regional multidisciplinary invasive species management coordination team to determine the appropriate Rapid Response provisions and allowed treatments in your area.

Understanding the risks associated with the application of Lineage Clearstand Herbicide is essential to aid in preventing off-site injury to desirable vegetation and agricultural crops. The risk of off-site movement both during and after application may be affected by a number of site specific factors such as the nature, texture and stability of the soil, the intensity and direction of prevailing winds, vegetative cover, site slope, rainfall, drainage patterns, and other local physical and environmental conditions. A careful evaluation of the potential for off-site movement from the intended application site, including movement of treated soil by wind or water erosion, must be made prior to using Lineage Clearstand Herbicide. This evaluation is particularly critical where desirable vegetation or crops are grown on neighboring land for which the use of Lineage Clearstand Herbicide is not labeled. If prevailing local conditions may be expected to result in off-site movement and cause damage to neighboring desirable vegetation or agricultural crops, do not apply Lineage Clearstand Herbicide.

Before applying Lineage Clearstand Herbicide the user must read and understand all label directions, precautions and restrictions completely, including these requirements for a site specific evaluation. If you do not understand any of the instructions or precautions on the label, or are unable to make a site specific evaluation yourself, consult your local agricultural dealer, cooperative extension service, land managers, professional consultants, or other qualified authorities familiar with the area to be treated. If you still have questions regarding the need for site specific considerations, please call 1-800-331-2867.
