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