GENERAL INFORMATION

 

PLATEAU herbicide is an aqueous solution to be mixed with water and an adjuvant and applied as a spray solution to provide weed control and/or turf height suppression on pastures, rangeland (see “GUIDELINES FOR RANGELAND USE” section), Federal Conservation Reserve Program (CRP) land and noncropland areas including noncropland areas that may be grazed or cut for hay.Examples of noncropland areas include, but are not limited torailroad, utility, pipeline and highway rights-of-way, railroad crossings, utility plant sites, petroleum tank farms, pumping installations, non-agricultural fence rows, storage areas, non-irrigation ditchbanks, prairie sites, airports, industrial turf, golf courses, recreational and non-residential turf and other similar areas.PLATEAU herbicide may be used for the release of bermudagrass, bahiagrass, smooth bromegrass, wheatgrass, “wildtype” common Kentucky bluegrass, native prairiegrass, wildflowers, crown vetch, other grasses and certain legumes.PLATEAU herbicide can also be used for weed control during the establishment of native prairiegrasses and other grasses (see “REVEGETATION WITH PRAIRIEGRASSES AND OTHER FORAGE GRASSES” section).

PLATEAU herbicide is readily absorbed through leaves, stems, and roots and is translocated rapidly throughout the plant, with accumulation in the meristematic regions.Treated plants stop growing soon after spray application.Chlorosis appears first in the newest leaves, and necrosis spreads from this point. In perennials, the herbicide is translocated into, and kills, underground storage organs which prevents regrowth.Chlorosis and tissue necrosis may not be apparent in some plant species for several weeks after application.Complete kill of plants may not occur for several weeks after application.Adequate soil moisture is important for optimum PLATEAU herbicide activity.When adequate soil moisture is present, PLATEAU herbicide will provide residual control of susceptible germinating weeds.Activity on established weeds will depend on the weed species and rooting depth.PLATEAU herbicide is rainfast one hour after application.

 

PLATEAU herbicide will control annual and perennial grasses and broadleaf weeds and vine species.PLATEAU herbicide will provide residual control of labeled weeds which germinate in the treated area.Certain brush species and ornamentals may be injured by direct application of PLATEAU herbicide to their foliage.This product may be applied either preemergence or postemergence to the weeds.However, post emergence application is the method of choice in most situations, particularly for perennial species.For maximum activity, weeds should be growing vigorously at the time of postemergence applications and the spray solution should include an adjuvant (see "SPRAY ADJUVANTS FOR POSTEMERGENCE APPLICATIONS” section ).These solutions may be applied as a broadcast or as a spot treatment using backpack, or ground equipment.

 

PLATEAU herbicide may be applied in the dormant or growing season for weed control.

 

Tolerance of desirable grass species to PLATEAU herbicide may be reduced when grasses are stressed due to insect damage, disease, environmental conditions, shade, poorly drained soils or other causes.

 

Depending on the turf type being treated, some yellowing of turf may occur with applications during the growing season.Depending on weather conditions, yellowing will usually disappear in 2 to 4 weeks.

 

PLATEAU herbicide should not be applied to newly seeded or sprigged grass stands, unless otherwise stated in this label (see “REVEGETATION WITH PRAIRIEGRASSES AND OTHER FORAGE GRASSES” section).

 

MIXING INSTRUCTIONS

 

Fill the spray tank one-half to three-quarters full with clean water.Use a calibrated measuring device to measure the required amount of PLATEAU herbicide.Add PLATEAU herbicide to the spray tank while agitating.Fill the remainder of the tank with water.

 

For postemergence applications, add a surfactant to the spray tank (see “SPRAY ADJUVANTS FOR POSTEMERGENCE APPLICATIONS” section of this label for specific recommendations).Maintain agitation while spraying to ensure a uniform spray mixture.An antifoaming agent may be added to the tank if needed.

 

When tank-mixing PLATEAU herbicide with recommended herbicides, add wettable powders, dispersible granules or other dry formulations first, then EC’s, then PLATEAU herbicide, and then an adjuvant.

 

SPRAYING INSTRUCTIONS

 

DO NOT apply during windy or gusty conditions unless applications are being made with a drift control agent and/or an enclosed or shielded spray system.DO NOT apply if rainfall is threatening.Rainfall within 1 hour after PLATEAU herbicide application may reduce weed control.

 

GROUND APPLICATIONS:

 

Uniformly apply with properly calibrated ground equipment in 2 or more gallons of water per acre. Application equipment, specially designed to make low volume application should be used when making applications using less than 10 gallons of water per acre.A spray pressure of 20 to 40 psi is recommended.

 

To achieve acceptable control of the target vegetation, good spray coverage of the weed foliage (postemergence) or soil surface (preemergence) is required.To achieve good spray coverage the sprayer must be calibrated to deliver the recommended spray volume and pressure and adjust the spray boom height to ensure proper coverage of weed foliage or soil surface (according to the manufacturer's recommendation).Avoid overlaps when spraying.

 

SPOT TREATMENTS:

 

To prepare the spray solution, thoroughly mix in water 0.25 to 1.5% (0.3 to 1.9 oz/gallon water) PLATEAU herbicide plus an adjuvant (see “SPRAY ADJUVANTS FOR POSTEMERGENCE APPLICATIONS” section).A methylated seed oil at 1% v/v is the recommended spray adjuvant except when treating seedling prairiegrasses and wildflowers.See section on desired species and do not exceed the recommended PLATEAU rate per acre.Also see “WEEDS CONTROLLED” and “SPECIAL WEED CONTROL” sections for specific rate and/or tank-mix recommendations.

 

AERIAL APPLICATION:

 

All precautions should be taken to minimize or eliminate spray drift.Fixed wing aircraft and helicopters can be used to apply PLATEAU herbicide, however, when making applications by fixed wing aircraft maintain appropriate buffer zonesto prevent spray drift out of the target area.Aerial equipment designed to minimize spray drift such as a helicopter equipped with a MICROFOILÔ boom, or THRU-VALVEÔ boom or raindrop nozzles, must be used and calibrated.Except when applying with a MICROFOIL boom, a drift control agent may be added at the recommended label rate.To avoid drift, applications should not be made during inversion conditions, when winds are gusty, or under any other conditions that promote spray drift.

 

Uniformly apply recommended amount of PLATEAU herbicide, using enough water volume to provide adequate coverage of target area or foliage.Include an adjuvant in the spray solution (see "SPRAYADJUVANTS FOR POSTEMERGENCE APPLICATIONS" section). A foam reducing agent may be added at the recommended rate, if needed.Aerial application to target species growing under the canopy of trees and brush may not receive sufficient spray coverage for effective control.For weed species with a recommended fall application timing (see “SPECIAL WEED CONTROL” section), delaying the aerial application until trees and brush have dropped their leaves can improve weed control and reduce the potential for tree and brush injury (see “TOLERANCE OF TREES AND BRUSH TO PLATEAU HERBICIDE” section).

 

IMPORTANT:Thoroughly clean application equipment, including landing gear, immediately after use of this product.Prolonged exposure of this product to uncoated steel (except stainless steel) surfaces may result in corrosion and failure of the exposed part.The maintenance of an organic coating (paint) may prevent corrosion.

 

Avoid overlaps when spraying.

 

SPRAY ADJUVANTS FOR POSTEMERGENCE APPLICATIONS

 

Postemergence applications of PLATEAU herbicide require a spray adjuvant.See "SPECIAL WEED CONTROL" section.Due to variations in surfactant contents, certain surfactants containing high amounts of alcohols, paraffin based petroleum oils, and other compounds which can increase phytotoxicity to desirable vegetation, it is recommended to choose a low phytotoxic surfactant.

 

Methylated Seed Oils or Vegetable Oil Concentrates:Instead of a surfactant, a methylated vegetable-based seed oil concentrate containing 5 to 20% surfactant and the remainder of the methylated vegetable oil may be used at the rate of 1.5 to 2 pints per acre.Methylated seed oils provide their greatest effects at 30 GPA or less.At spray volumes above 50 GPA, their advantage appears negated.When using spray volumes greater than 30 gallons per acre methylated seed oil or vegetable based seed oil concentrates should be mixed at a rate of 1% of the total spray volume or alternatively use a nonionic surfactant as described below.Research indicates these oils may aid in deposition and uptake of PLATEAU herbicide for hard-to-control perennials, waxy leaf species or when plants are under moisture or temperature stress.DO NOT use a methylated seed oil or vegetable oil concentrate when making applications to newly emerged seedling prairiegrasses or wildflowers as injury may occur.

 

Nonionic Surfactants:Use a nonionic surfactant at the rate of 0.25% v/v or higher (see manufacturer's label) of the spray solution (0.25% v/v is equivalent to 1 quart in 100 gallons).For best results, select a nonionic surfactant with a HLB (hydrophilic to lipophilic balance) ratio between 12 and 17 and having at least 60% surfactant in the formulated product (alcohols, fatty acids, oils, ethylene glycol or diethylene glycol should not be considered as surfactants to meet the above requirements).

 

Silicone-Based Surfactants:See manufacturer's label for specific rate recommendations.Silicone-based surfactants may reduce the surface tension of the spray droplet allowing greater spreading on the leaf surface as compared to conventional nonionic surfactants.However, some silicone-based surfactants may dry too quickly, limiting herbicide uptake and higher spray volumes may exhibit “run-off”.

 

Fertilizer/Surfactant Blends:Nitrogen-based liquid fertilizers such as 28%N, 32%N, 10-34-0, or ammonium sulfate, may be added at the rate of 2 to 3 pints per acre in combination with the recommended rate of nonionic surfactant or methylated seed oil.Research indicates that nitrogen based fertilizers aid in the burndown of annual weeds and increase PLATEAU herbicide uptake through waxy leaf species.However, fertilizers may increase phytotoxicity to desired species and newly emerged seedling prairiegrasses and wildflowers.The use of liquid fertilizers at a rate of 2 to 3 pints per acre in a tank-mix without a nonionic surfactant or a methylated seed oil is not recommended and may result in herbicide failure.Only when liquid fertilizer is used as the spray carrier is no additional spray adjuvant required.

 

TANK MIXES

 

For use in noncrop areas, PLATEAU herbicide may be tank-mixed with PENDULUMÒ herbicide for additional control of late season annual grasses and certain broadleaves.For additional weed control in noncrop areas, PLATEAU herbicide may be tank-mixed with ACCORDÔ, ROUNDUPÔ PRO, glyphosate, ARSENALÒ herbicide, SAHARAÒ DG herbicide, diuron, CAMPAIGNÔ, FINALEÔ, GARLONÔ 3A, MSMA, VANQUISHÔ, OUSTÔ, ESCORTÔ, TORDONÔ, or other labeled products.A compatibility test is advised for products not listed.2,4-D and other phenoxy type herbicides have resulted in reduced control of perennial grass weeds.

 

For tank mix recommendations for use in bermudagrass pastures, refer to the “DIRECTIONS FOR USE IN BERMUDAGRASS PASTURES AND HAY MEADOWS” section.

 

DO NOT tank mix with organophosphate insecticides or use the same year as PLATEAU herbicide when making applications to newly planted areas.

 

Consult manufacturer's labels for specific rates and weeds controlled.Always follow the more restrictive label when making an application involving tank-mixes.

 

FOR WEED CONTROL IN PASTURE AND RANGELAND

 

For the control of undesirable weeds in pasture and rangeland (see “GUIDELINES FOR RANGELAND USE” section), apply PLATEAU herbicide at 2 to 12 oz. per acre as a broadcast treatment or as a ½ to 1% solution for spot treatments.See appropriate sections of this label for specific use directions.

 

GUIDELINES FOR RANGELAND USE

 

PLATEAU herbicide may be applied to rangeland for the control of undesirable vegetation in order to achieve one or more of the following vegetation management objectives:

 

  1. The control of undesirable (non-native, invasive and noxious) plant species
  2. The control of undesirable vegetation in order to aid in the establishment of desirable rangeland plant species.
  3. The control of undesirable vegetation in order to aid in the establishment of desirable rangeland vegetation following a fire.
  4. The control of undesirable vegetation for purposes of wildfire fuel reduction.
  5. The release of existing desirable rangeland plant communities from the competitive pressure of undesirable plant species.
  6. The control of undesirable vegetation for purposes of wildlife habitat improvement.

 

To ensure the protection of threatened and endangered plants when applying PLATEAU herbicide to rangeland:

 

  1. Federal agencies must follow NEPA regulations to ensure protection of threatened and endangered plants.
  2. State agencies must work with the Fish and Wildlife Service or the Service's designated state conservation agency to ensure protection of threatened and endangered plants.
  3. Other organizations or individuals must operate under a Habitat Conservation Plan if threatened or endangered plants are known to be present on the land to be treated.

 

Please see the appropriate section(s) of this label for specific use directions for the desired rangeland vegetation management objective.

 

PLATEAU herbicide should only be applied to a given rangeland acre as specific weed problems arise.For the control of annual weed species such as cheatgrass, downy brome and medusahead rye, a single application of PLATEAU herbicide that coincides with the successful establishment and/or release of desirable rangeland vegetation and the use of available IPM can provide effective, sustainable control of the annual weed problem.For difficult to control perennial weed species such as leafy spurge, dalmatian toadflax and Russian knapweed, a single broadcast application of PLATEAU herbicide should be effective in most cases.If needed, spot treatments with PLATEAU herbicide can be used to control any remnant plants or new seedlings that may emerge.Long term control of undesirable weed species ultimately depends on the successful use of land management practices that promote the growth and sustainability of desirable rangeland plant species.

 

DIRECTIONS FOR USE IN BERMUDAGRASS PASTURES AND HAY MEADOWS

 

PLATEAU herbicide may be used postemergence at a rate of 4 to 12 oz per acre for control of undesirable winter and summer annual and perennial grasses in bermudagrass pastures and hay meadows (see rate and timing recommendations below).PLATEAU herbicide may be used on common and coastal varieties of bermudagrass including, but not restricted to Tifton 44, 78 and 85, Alicia and Russell.Suppression of bermudagrass growth for 30 to 45 days or longer may occur, depending upon growth conditions after application.Jiggs bermudagrass in particular has shown greater sensitivity to PLATEAU herbicide.Do not use PLATEAU herbicide if this growth response is not acceptable.

 

In bermudagrass pastures and hay meadows, even and thorough spray coverage is necessary to achieve the desired level of weed control.To ensure proper spray coverage, the sprayer must be calibrated to deliver the recommended spray volume and pressure and the spray boom height adjusted to ensure proper coverage of weed foliage (according to the manufacturer's recommendation).The use of boomless or flood type nozzles is not recommended and may result in decreased weed control.

 

DO NOT apply PLATEAU to drought stressed bermudagrass.

DO NOT use PLATEAU for the establishment of sprigged or seeded bermudagrass.

DO NOT use PLATEAU on World Feeder varieties of bermudagrass.

DO NOT apply PLATEAU during transition from dormancy to full green-up.

AVOID applications of PLATEAU to newly aerated fields for 30 days after aeration.

 

Spring Applications and Bermudagrass Tolerance:Spring application of PLATEAU herbicide should only be made after bermudagrass has reached 100% green-up.PLATEAU applications to bermudagrass during transition from winter dormancy to 100% green-up will significantly delay green-up and growth of bermudagrass, resulting in the potential loss of one or more cuttings.Bermudagrass can be considered to have reached 100% green-up only when all stolons (runners) have developed new active growth.Partial green-up may be characterized by the green appearance of new bermudagrass growth in the field, but upon close inspection some of the stolons may not have begun to grow.PLATEAU applications made at this time can still cause significant reductions in bermudagrass growth and development and should be delayed until 100% green-up.To minimize bermudagrass response from spring applications, all applications should be made postemergence to the targeted summer annual or perennial weeds.See specific use directions below for appropriate postemergence timing for targeted weed species.

 

Postemergent Control of Summer Annual and Perennial Grass Weeds:Apply PLATEAU herbicide after bermudagrass has reached full green-up and target grass weeds are at the desired growth stage (see recommended rates and growth stages below).Early Spring applications made during transition from dormancy to green-up will delay bermudagrass green-up and subsequent bermudagrass growth.Recommended PLATEAU herbicide applications may cause some stolon internode shortening and yellowing of the bermudagrass.The use of a nitrogen fertilizer (32-0-0 or 28-0-0) as the spray carrier will shorten recovery time.

 

For summer annual grass control apply 4 to 6 oz per acre of PLATEAU early postemergence (2 to 4 leaf stage) following full bermudagrass green-up.If target weeds are at or above boot stage, apply 6 to 8 oz per acre for control.Always add a surfactant when applying PLATEAU herbicide unless liquid fertilizer is being used as the spray carrier.PLATEAU will provide some preemergence annual grass control, however initial applications need to be made postemergence to target weed species.

 

For summer perennial grass control apply 6 to 12 oz per acre of PLATEAU postemergence following bermudagrass green-up. If higher rates (8 to 12 oz per acre) are needed for control of target species, PLATEAU herbicide can be applied in the fall before killing frost occurs.When making a fall application, if bermudagrass has been cut for hay, allow sufficient regrowth of target species before making application.Always add a surfactant when applying PLATEAU herbicide unless liquid fertilizer is being used as the spray carrier.

 

Postemergent Control of Winter Annual and Perennial Grass Weeds:Apply PLATEAU herbicide when bermudagrass is dormant prior to green-up.If bermudagrass has green tissue at the root crown or stolons, applications of PLATEAU may delay green-up of bermudagrass and subsequent bermudagrass growth.During mild winters, bermudagrass in the deep South may not be completely dormant.Applications in these areas should be avoided if delayed green-up cannot be tolerated.

 

For winter annual and perennial grass control, apply 6 to 12 oz per acre of PLATEAU postemergent, when bermudagrass is dormant.The addition of 16 to 24 oz per acre of ROUNDUP ULTRAÔ or glyphosate equivalent will increase control of larger winter annual and cool season perennial grasses.Always add a surfactant when applying PLATEAU herbicide unless liquid fertilizer is being used as the spray carrier.
