ENVIRONMENTAL HAZARDS
Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the
mean high water mark. Do not contaminate water when disposing of equipment washwaters or rinsate.
Apply this product only as directed on the label.
This chemical is known to leach through soil into ground water under certain conditions as a result of
agricultural use. Use of this chemical in areas where soils are permeable, particularly where the water
table is shallow, may result in ground water contamination.
GROUND AND SURFACE WATER PROTECTION
Point source contamination: To prevent point source contamination, do not mix or load this pesticide
product within 50 feet of wells (including abandoned wells and drainage wells), sink holes, perennial or
intermittent streams and rivers, and natural or impounded lakes and reservoirs. Do not apply pesticide
product within 50 feet of wells. This setback does not apply to properly capped or plugged abandoned
wells and does not apply to impervious pad or properly diked mixing/loading areas as described below.
Mixing, loading, rinsing, or washing operations performed within 50 feet of a well are allowed only when
conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be on
or move across the pad. The pad must be self-contained to prevent surface water flow over or from the
pad. The pad capacity must be maintained at 110% that of the largest pesticide container or application
equipment used on the pad and have sufficient capacity to contain all product spills, equipment or
container leaks, equipment wash waters, and rainwater that may fall on the pad. The containment
capacity does not apply to vehicles delivering pesticide shipments to the mixing/loading site. States may
have in effect additional requirements regarding wellhead setbacks and operational containment.
Care must be taken when using this product to prevent: a) back siphoning into wells, b) spills or c)
improper disposal of excess pesticide, spray mixtures or rinsates. Check valves or antisiphoning devices
must be used on all mixing equipment.
Movement bv surface runoff or through soil: Do not apply under conditions which favor runoff. Do not
apply to impervious substrates such as paved or highly compacted surfaces in areas with high potential
for ground water contamination. Ground water contamination may occur in areas where soils are
permeable or coarse and ground water is near the surface. Do not apply to soils classified as sand with
less than 3% organic matter and where ground water depth is shallow. To minimize the possibility of
ground water contamination, carefully follow application rate specifications as affected by soil type in the
product information section of this label.
Movement by water erosion of treated soil: Do not apply or incorporate this product through any type of
irrigation equipment nor by flood or furrow irrigation. Ensure treated areas have received at least one-
half inch rainfall (or irrigation) before using tailwater for subsequent irrigation of other fields.

PRODUCT INFORMATION
STERLING BLUE is a water-soluble formulation intended for control and suppression of many annual,
biennial, and perennial broadleaf weeds, as well as woody brush and vines listed in Table 1. General
Weed List, Including ALS- and Triazine-Resistant Biotypes. STERLING BLUE may be used for control of
these weeds in asparagus, corn, cotton, conservation reserve programs, fallow cropland, forestry sites,
grass grown for seed, hay, proso millet, pasture, rangeland, rights-of-way general farmstead
(noncropland), small grains, sorghum, soybean, sugarcane, and turf.
Mode of Action
STERLING BLUE is readily absorbed by plants through shoot and root uptake, translocates throughout the
plant's system, and accumulates in areas of active growth. STERLING BLUE interferes with the plant's
growth hormones (auxins) resulting in death of many broadleaf weeds.
Resistance Management
STERLING BLUE has a low probability of selecting for resistant weed biotypes.
Cleaning Spray Equipment
Clean application equipment thoroughly by using a strong detergent or commercial sprayer cleaner,
according to the manufacturer's directions, and then triple rinsing the equipment before and after
applying this product.

APPLICATION INSTRUCTIONS
STERLING BLUE can be applied to actively growing weeds as aerial, broadcast, band, or spot spray
applications using water or sprayable fertilizer as a carrier. For STERLING BLUE application rates for
control or suppression by weed type and growth stage see Table 2. STERLING BLUE Application Rates for
Control or Suppression by Weed Type and Growth Stage. For crop-specific application timing and other
details, refer to the Crop-Specific Information section.
To avoid uneven spray coverage, do not apply STERLING BLUE during periods of gusty wind or when
wind is in excess of 15 mph.
Avoid off-target movement. Use extreme care when applying STERLING BLUE to prevent injury to
desirable plants and shrubs.
Cultivation
Do not cultivate within 7 days after applying STERLING BLUE.
Sensitive Crop Precautions
STERLING BLUE may cause injury to desirable trees and plants, particularly beans, cotton, flowers, fruit
trees, grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, tomatoes, and other
broadleaf plants when contacting their roots, stems, or foliage. These plants are most sensitive to
STERLING BLUE during their development or growing stage.
Recommendations to avoid herbicide drift
• Use coarse sprays (volume median diameter of 400 microns or more) to avoid potential herbicide drift.
Select nozzles that are designed to produce minimal amounts of fine spray particles (less than 200
microns). Examples of nozzles designed to produce coarse sprays via ground applications are
Delavan® Raindrops, Spraying Systems XR (excluding 110° tips) flat fans, Turbo Teejets®, Turbo
Floodjets®, or large capacity flood nozzles such as D10, TK10, or greater capacity tips.
• Keep the spray pressure at or below 20 psi and the spray volume at or above 20 gallons per acre (for
ground broadcast applications), unless otherwise required by the manufacturer of drift-reducing
nozzles. Consult your spray nozzle supplier concerning the choice of drift-reducing nozzles.
• Agriculturally approved drift-reducing additives may be used.
Aerial Application Methods and Equipment
Water Volume: Use 1-10 gallons of water per acre (2 -20 gallons of diluted spray per treated acre for
preharvest uses). Use the higher spray volume when treating dense or tall vegetation.
Application Equipment: Select nozzles designed to produce minimal amounts of fine spray particles. Make
aerial applications at the lowest safe height to reduce exposing the spray to evaporation and wind.
The applicator must follow the most restrictive use cautions to avoid drift hazards, including those found
in this labeling, as well as state and local regulations and ordinances.
Do not use aerial equipment if spray particles can be carried by the wind into areas where sensitive crops
or plants are growing or when temperature inversions exist.
Ground Application (Banding)
When applying STERLING BLUE by banding, determine the amount of herbicide and water volume
needed using the following formula:
Bandwidth in inches x Broadcast rate = Banding herbicide
Row width in inches per acre rate per acre
Bandwidth in inches
Row width in inches
x Broadcast
volume per acre
Banding water
volume rate per acre
Ground Application (Broadcast)
Water Volume: Use 3 - 50 gallons of spray solution per broadcast acre for optimal performance. Use the
higher spray volume when treating dense or tall vegetation.
Application Equipment: Select nozzles designed to produce minimal amounts of fine spray particles. Spray
with nozzles as close to the weeds as is practical for good weed coverage.
Ground Application (Wipers)
STERLING BLUE may be applied through wiper application equipment to control or suppress actively
growing broadleaf weeds, brush, and vines. Use a solution containing 1 part STERLING BLUE to 1 part
water. Do not contact desirable vegetation with herbicide solution. Wiper application may be made to
crops (including pastures) and non-cropland areas described in this label with the exception of cotton,
sorghum, and soybean.

1 Rates below 8 fluid ounces per acre may provide control or suppression but should typically be
applied with other herbicides that are effective on the same species and biotype.
2 Species notes in Table 2 will require tank mixes for adequate control.
3 Do not broadcast apply more than 32 fluid ounces per acre for single application. Use the
higher level of listed rate ranges when treating dense vegetation growth or perennial weeds with
well established root growth. Rates higher than 32 fluid ounces per acre are for spot treatment
only. Do not exceed 64 fluid ounces per acre per year.
ADDITIVES
To improve postemergence weed control, agriculturally approved surfactants, sprayable fertilizers (urea
ammonium nitrate, or ammonium sulfate), or crop oil concentrate may be added, particularly in dry
growing conditions. (Refer to Table 3. Additive Rate Per Acre.)
Nitrogen Source
• Urea ammonium nitrate (UAN): Use 2-4 quarts of UAN (commonly referred to as 28%, 30%, or 32%
nitrogen solution) per acre. Do not use brass or aluminum nozzles when spraying UAN.
• Ammonium sulfate (AMS): AMS at 2.5 pounds per acre may be substituted for UAN. Use high-quality
AMS (spray grade) to avoid plugging of nozzles. Other sources of nitrogen are not as effective as
those mentioned. Winfield Solutions, LLC does not recommend applying AMS, if applied in less than 10
gallons per acre because of potential problems with precipitation in reduced volumes. Use AMS only if
it has been demonstrated to be successful in local experience.
Nonionic Surfactant
The standard label recommendation is 1 pint of an 80% active nonionic spray surfactant per 100 gallons
of water. For certain weeds, a higher spray surfactant rate is recommended.

Oil Concentrate
A crop oil concentrate must contain either a petroleum or .vegetable oil base and must meet all of the
following criteria:
• be nonphytotoxic,
• contain only EPA-exempt ingredients,
• provide good mixing quality in the jar test, and
• be successful in local experience.
The exact composition of suitable products will vary; however, vegetable and petroleum oil concentrates
should contain emulsifiers to provide good mixing quality. Highly refined vegetable oils have proven more
satisfactory than unrefined vegetable oils. For additional information, see Compatibility Test for Mix

Compatibility Test for Mix Components
Before mixing components, always perform a compatibility jar test.
For 20 gallons per acre spray volume, use 3.3 cups (800 ml) of water. For other spray volumes, adjust
accordingly. Only use water from the intended source at the source temperature.
Add components in the sequence indicated in the Mixing Order using 2 teaspoons for each pound or 1
teaspoon for each pint of recommended label rate per acre.
Always cap the jar and invert 10 cycles between component additions.
When the components have all been added to the jar, let the solution stand for 15 minutes. Evaluate the
solution for uniformity and stability. The spray solution should not have free oil on the surface, nor fine
particles that precipitate to the bottom, nor thick (clabbered) texture. If the spray solution is not
compatible, repeat the compatibility test with the addition of a suitable compatibility agent. If the solution
is then compatible, use the compatibility agent as directed on its label. If the solution is still incompatible,
do not mix the ingredients in the same tank.
Mixing Order
1. Water. Begin by agitating a thoroughly clean sprayer tank three-quarters full of clean water.
2. Agitation. Maintain constant agitation throughout mixing and application.
3. Inductor. If an inductor is used, rinse it thoroughly after each component has been added.
4. Products in PVA bags. Place any product contained in water-soluble PVA bags into the mixing tank.
Wait until all water-soluble PVA bags have fully dissolved and the product is evenly mixed in the
r
spray tank before continuing.
5. Water-dispersible products (dry flowables, wettable powders, suspension concentrates,, or suspo-
emulsions).
6. Water-soluble products, (such as STERLING BLUE)
7. Emulsifiable concentrates (such as oil concentrate when applicable).
8. Water-soluble additives (such as AMS or DAN when applicable).
9. Remaining quantity of water.
Maintain constant agitation during application.

CROP-SPECIFIC INFORMATION
ASPARAGUS
Apply STERLING BLUE to emerged and actively growing weeds in 40 - 60 gallons of diluted spray per
treated acre immediately after cutting the field, but at least 24 hours before the next cutting. Multiple
applications may be made per growing season.
If spray contacts emerged spears, crooking (twisting) of some spears may result. If such crooking occurs,
discard affected spears.
Rates: Apply 8-16 fluid ounces of STERLING BLUE to control annual sowthistle, black mustard, Canada
and Russian thistle, and redroot pigweed, (carelessweed).
Apply 16 fluid ounces of STERLING BLUE to control common chickweed, field bindweed, nettleleaf
14
goosefoot, and wild radish. Multiple applications may be made per growing season. Do not exceed a total
of 16 fluid ounces of STERLING BLUE per treated acre, per crop year.
Do not harvest prior to 24 hours after treatment.
Do not use in the Coachella Valley of California.
Asparagus Tank Mixes
Apply 8-16 fluid ounces of STERLING BLUE with glyphosate (Roundup PowerMAX® herbicide) or 2,4-D to
improve control of Canada thistle and field bindweed.
BETWEEN CROP APPLICATIONS
PREPLANT DIRECTIONS (POSTHARVEST. FALLOW. CROP STUBBLE. SET-ASIDE") FOR BROADLEAF WEED
CONTROL:
STERLING BLUE can be applied either postharvest in the fall, spring, or summer during the fallow period
or to crop stubble/set-aside acres. Apply STERLING BLUE as a broadcast or spot treatment to emerged
and actively growing weeds after crop harvest (postharvest) and before a killing frost or in the fallow
cropland or crop stubble the following spring or summer.
See Crop-Rotational Restrictions in General Restrictions and Limitations for the recommended interval
between application and planting to prevent crop injury.
Rates and Timings:
Apply 4 - 32 fluid ounces of STERLING BLUE per acre. Refer to Table 2 to determine use rates for specific
targeted weed species. For best performance, apply STERLING BLUE when annual weeds are less than 6"
tall, when biennial weeds are in the rosette stage and to perennial weed regrowth in late summer or fall
following a mowing or tillage treatment. The most effective control of upright perennial broadleaf weeds
such as Canada thistle and Jerusalem artichoke occurs if STERLING BLUE is applied when the majority of
weeds have at least 4 - 6" of regrowth or for weeds such as field bindweed and hedge bindweed that are
in or beyond the full bloom stage.
Avoid disturbing treated areas following application. Treatments may not kill weeds that develop from
seed or underground plant parts such as rhizomes or bulblets, after the effective period for STERLING
BLUE. For seedling control, a follow-up program or other cultural practices could be instituted. For small
grain in-crop uses of STERLING BLUE, refer to the small grain section for details.
Between Crop Tank Mixes
In tank mixes with one or more of the following herbicides, apply 4-16 fluid ounces of STERLING BLUE
per acre for control of annual weeds, or 16 - 32 fluid ounces of STERLING BLUE per acre for control of
biennial and perennial weeds:
• Ally® • Gramoxone Inteon™
• Amber® • Kerb®
• Atrazine • Landmaster® BW
• Curtail® • Paramount®
• Cyclone® • Tordon® 22K
• Fallow Master® • Touchdown®

15
CORN (FIELD, POP, SEED, AND SILAGE)
Direct contact of STERLING BLUE with corn seed must be avoided. If corn seeds are less than 1.5" below
the soil surface, delay application until corn has emerged.
Applications of STERLING BLUE to corn during periods of rapid growth may result in temporary leaning.
Corn will usually become erect within 3-7 days. Cultivation should be delayed until after corn is growing
normally to avoid breakage.
Corn may be harvested or grazed for feed once the crop has reached the ensilage (milk) stage or later in
maturity. Up to 2 applications of STERLING BLUE may be made during a growing season. Sequential
applications must be separated by 2 weeks or more.
Do not apply STERLING BLUE to seed corn or popcorn without first verifying with your local seed corn
company (supplier) the selectivity of STERLING BLUE on your inbred line or variety of popcorn. This
precaution will help avoid potential injury of sensitive varieties.
Avoid using crop oil concentrates after crop emergence as crop injury may result. Use crop oil
concentrates only in dry conditions when corn is less than 5" tall and when applying STERLING BLUE
alone or tank mixed with atrazine.
Use of sprayable fluid fertilizer as the carrier is not recommended for applications of STERLING BLUE
made after corn emergence.
STERLING BLUE is not registered for use on sweet corn.
PREPLANT AND PREEMERGENCE APPLICATION IN NO TILLAGE CORN:
Rates: Apply 16 fluid ounces of STERLING BLUE per acre on medium- or fine-textured soils containing
2.5% or greater organic matter. Use 8 fluid ounces of STERLING BLUE per acre on coarse soils (sand,
loamy sand, and sandy loam) or medium- and fine-textured soils with less than 2.5% organic matter.
Timing: STERLING BLUE can be applied to emerged weeds before, during, or after planting a corn crop.
When planting into a legume sod (e.g. alfalfa or clover), apply STERLING BLUE after 4 - 6" of regrowth
has occurred.
PREEMERGENCE APPLICATION IN CONVENTIONAL OR REDUCED TILLAGE CORN:
Rates: Apply 16 fluid ounces of STERLING BLUE per treated acre to medium- or fine-textured soils that
contain 2.5% organic matter or more. Do not apply to coarse-textured soils (sand, loamy sand, or sandy
loam) or any soil with less than 2.5% organic matter untilafter corn emergence (see Early
Postemergence uses below).
Timing: STERLING BLUE may be applied after planting and prior to corn emergence. Preemergence
application of STERLING BLUE does not require mechanical incorporation to become active. A shallow
mechanical incorporation is recommended if the application is not followed by adequate rainfall or
sprinkler irrigation. Avoid tillage equipment (e.g. drags, harrows) that concentrate treated soil over seed
furrow, as seed damage could result.
Preemergence control of cocklebur, jimsonweed, and velvetleaf may be reduced if conditions such as low
temperature or lack of soil moisture cause delayed or deep germination of weeds.
16
EARLY POSTEMERGENCE APPLICATION IN ALL TILLAGE SYSTEMS:
Rates: Apply 16 fluid ounces of STERLING BLUE per treated acre. Reduce the rate to 8 fluid ounces of
STERLING BLUE per treated acre for corn grown on coarse-textured soils (sand, loamy sand, and sandy
loam).
Timing: Apply between corn emergence and the 5-leaf stage or 8" tall, whichever occurs first. Refer to
Late Postemergence Application if the sixth true leaf is emerging from whorl or the corn is greater than
8" tall.
LATE POSTEMERGENCE APPLICATION:
Rate: Apply 8 fluid ounces of STERLING BLUE per treated acre.
Timing: Apply STERLING BLUE from 8 - 36" tall corn or 15 days before tassel emergence, whichever
comes first. For best performance, apply when weeds are less than 3" tall.
Apply directed spray when corn leaves prevent proper spray coverage, sensitive crops are growing
nearby, or tank mixing with 2,4-D. Do not apply STERLING BLUE when soybeans are growing nearby if
any of these conditions exist:
• corn is more than 24" tall
• soybean are more than 10" tall
• soybean have begun to bloom
Corn Tank Mixes or Sequential Uses
When using tank mix or sequential applications with STERLING BLUE, always follow the companion
product label to determine specific use rates by soil types, weed species, and weed or crop growth stage.

When tank mixing, applications immediately following extreme day or night
temperature fluctuations or applications when daytime temperatures do not
exceed 50° F may result in decreased weed control or crop injury. Delay
application until the temperatures warm and both weeds and crop resume
normal growth.
2,4-D
To provide maximum crop safety after corn emergence, use this tank mix
only after corn is greater than 8" tall and when application can be made
with drop pipes that direct spray beneath corn leaves and away from the
whorl of the corn. The maximum rate of 2,4-D recommended in this tank
mix is 0.25 pints per acre (0.125 pounds of acid equivalent per acre).
Dicamba DMA or
Marksman® Herbicide
Tank mixes with these products that contain dicamba must not exceed a
total combined rate of 0.50 pounds of dicamba acid equivalent per acre
(0.25 pound on coarse-textured soils or on any soil when corn is greater
than 8" tall). Sequential applications of these products must be separated
by a minimum of 2 weeks (unless the combined rate is less than 0.5 pounds
of dicamba acid equivalent and corn is 8" tall or less) and must not exceed
a combined total of 0.75 pounds dicamba acid equivalent per acre for in-
crop use.
Spirit™, Stinger®,
Hornet™, or Permit®
For improved control of velvetleaf, tank mix 0.5 ounce of Spirit, or 0.17 -
0.33 ounce Permit per acre with STERLING BLUE. For improved control of
Canada thistle, Stinger at 1.5 - 3 fluid ounces per acre or Hornet at 0.6 -1.2
ounces per acre may be tank mixed with STERLING BLUE. Use the higher
rate in the range for heavier infestations of these weeds.
COTTON
PREPLANT APPLICATION:
Apply up to 8 fluid ounces of STERLING BLUE per acre to control emerged broadleaf weeds prior to
planting cotton in conventional or conservation tillage systems.
For best performance, apply STERLING BLUE when weeds are in the 2 - 4 leaf stage and rosettes are less
than 2" across.
Following application of STERLING BLUE and a minimum accumulation of 1" of rainfall or overhead
irrigation, a waiting interval of 21 days is required per 8 fluid ounces per acre or less. These intervals
must be observed prior to planting cotton.
Do not apply preplant to cotton west of the Rockies.
Do not make STERLING BLUE preplant applications to cotton in geographic areas with average annual
rainfall less than 25".
18
If applying a spring preplant treatment following application of a fall preplant (postharvest) treatment,
then the combination of both treatments may not exceed 2 pounds acid equivalent per acre.
Cotton Tank Mixes
For control of grasses or additional broadleaf weeds, STERLING BLUE may be tank mixed with Caparol®,
Gramoxone Inteon™, and Roundup WeatherMAX® herbicides.
GRASS GROWN FOR SEED
Apply 8-16 fluid ounces of STERLING BLUE per treated acre on seedling grass after the crop reaches the
3 - 5 leaf stage. Apply up to 32 fluid ounces of STERLING BLUE on well-established perennial grass. For
best performance, apply STERLING BLUE when weeds are in the 2 - 4 leaf stage and rosettes are less
than 2" across. Use the higher level of listed rate ranges when treating more mature weeds or dense
vegetative growth.
To suppress annual grasses such as brome (downy and ripgut), rattail fescue, and windgrass, apply up to
32 fluid ounces of STERLING BLUE per treated acre in the fall or late summer after harvest and burning
of established grass seed crops. Applications should be made immediately following the first irrigation
when the soil is moist and before weeds have more than 2 leaves.
Do not apply STERLING BLUE after the grass seed crop begins to joint.
Refer to the Pasture, Hay, Rangeland, and General Farmstead section for grazing and feeding
restrictions.
Grass Seed Tank Mixes
STERLING BLUE may be applied in tank mixes with one or more of the following herbicides:
• Buctril®
. Curtail®
• Express®
• Karmex®
• MCPA amine
• Stinger®
• 2,4-D amine or ester
PROSO MILLET
For use only within Colorado, Nebraska, North Dakota, South Dakota, and Wyoming.
STERLING BLUE combined with 2,4-D will provide control or suppression of the annual broadleaf weeds
listed in Table 1.
Apply 4 ounces of STERLING BLUE with 0.375 pounds a.i. of 2,4-D. Apply the tank mix of STERLING
BLUE + 2,4-D as a broadcast or spot treatment to emerged and actively growing weeds and when proso
millet is in the 2 - 5 leaf stage. Use directions for 2,4-D products vary with manufacturers. Refer to a 2,4-
D product with labeling consistent with the crop stage timing for STERLING BLUE. Some types of proso
millet may be affected adversely by a tank mix of STERLING BLUE + 2,4-D.
Do not apply unless possible proso millet crop injury will be acceptable.
19
Restrictions for proso millet that is grazed or cut for hay are indicated in Table 6. Timing Restrictions for
Lactating Dairy Animals Following Treatment in Pasture, Hay, Rangeland, and General Farmstead section
of this label.
PASTURE, HAY, RANGELAND, AND GENERAL FARMSTEAD (NONCROPLAND)
STERLING BLUE is recommended for use on pasture, hay, range-land, and general farmstead (non-
cropland) (including fencerows and non-irrigation ditchbanks) for control or suppression of broadleaf
weed and brush species listed in Table 1.
STERLING BLUE may also be applied to non-cropland areas to control broadleaf weeds in noxious weed
control programs, districts, or areas including broadcast or spot treatment of roadsides and highways,
utilities, railroad, and pipeline rights-of-way. Noxious weeds must be recognized at the state level, but
programs may be administered at state, county, or other level.
STERLING BLUE uses described in .this section also pertain to small grains (forage sorghum, rye,
sudangrass, or wheat) grown for pasture use only. Some perennial weeds may be controlled with lower
rates of either STERLING BLUE or STERLING BLUE plus 2,4-D (refer to Table 2).
Rates and Timings
Refer to Table 2 for rate selection based on targeted weed or brush species. Some weed species will
require tank mixes for adequate control.
Rates above 32 fluid ounces of STERLING BLUE per acre are for spot treatments only. Do not broadcast
apply more than 32 fluid ounces per acre.
Retreatments may be made as needed; however, do not exceed a total of 32 fluid ounces of STERLING
BLUE per treated acre during a growing season.
Crop-Specific Restrictions and Limitations
Do not apply more than 16 fluid ounces of STERLING BLUE per acre to small grains grown for pasture.
Newly seeded areas may be severely injured if more than 16 fluid ounces of STERLING BLUE is applied
per acre.
Established grass crops growing under stress can exhibit various injury symptoms that may be more
pronounced if herbicides are applied. Bentgrass, carpetgrass, buffalo-grass, and St. Augustinegrass may
be injured if more than 16 fluid ounces of STERLING BLUE is applied per acre. Usually colonial
bentgrasses are more tolerant than creeping types. Velvetgrasses are most easily injured. Treatments will
kill or injure alfalfa, clovers, lespedeza, wild winter peas, vetch, and other legumes.
Table 6 lists the timing restrictions for grazing or harvesting hay from treated fields. There are no grazing
restrictions for animals other than lactating dairy animals.

STERLING BLUE can be applied using water, oil in water emulsions including invert systems, or sprayable
fluid fertilizer as a carrier (refer to the Compatibility Test for Mix Components).
To prepare oil in water emulsions, half-fill spray tank with water, then add the appropriate amount of
emulsifier. With continuous agitation, slowly add the herbicide and then the oil (such as diesel oil or fuel
oil) or a premix of oil plus additional emulsifier to spray tank. Complete filling of spray tank with water.
Maintain vigorous agitation during spray operation to prevent oil and water from forming separate layers.
STERLING BLUE may be applied broadcast using either ground or aerial application equipment.
Aerial Application:
• Spray Volume: Use 2-40 gallons of diluted spray per treated acre in a water-based carrier.
Ground Application:
• Spray Volume: Use 3 - 600 gallons of diluted spray per treated acre. The volume of spray applied will
depend on the height, density, and type of weeds or brush being treated and on the type of
equipment being used.
• Spot Treatments: STERLING BLUE may be applied to individual clumps or small areas of undesirable
vegetation using handgun or similar types of application equipment. Apply diluted sprays to allow
complete wetting (up to runoff) of foliage and stems.
Cut Surface Treatments:
STERLING BLUE may be applied as a cut surface treatment for control of unwanted trees and prevention
of sprouts of cut trees.
Rate: Mix 1 part STERLING BLUE with 1-3 parts water to create the application solution. Use the lower
dilution rate when treating difficult-to-control species.
• For Frill or Girdle Treatments: Make a continuous cut or a series of overlapping cuts using an axe to
girdle tree trunk. Spray or paint the cut surface with the solution.
• For Stump Treatments: Spray or paint freshly cut surface with the water mix. The area adjacent to the
bark should be thoroughly wet.
NOTE: For more rapid foliar effects, 2,4-D may be added to the solution.
Applications For Control of Dormant Multiflora Rose:
STERLING BLUE can be applied when plants are dormant as an undiluted spot treatment directly to the
soil or as a Lo-Oil basal bark treatment using an oil-water emulsion solution.
• Spot treatments: Spot treatment applications of STERLING BLUE should be applied directly to the soil
as close as possible to the root crown but within 6 - 8" of the crown. On sloping terrain, apply
STERLING BLUE to the uphill side of the crown; do not apply when snow or water prevents applying
STERLING BLUE directly to the soil. The use rate of STERLING BLUE depends on the canopy diameter
of the multiflora rose.
Examples: Use 0.25,1.0, or 2.35 fluid ounces of STERLING BLUE respectively, for 5,10, or 15 feet
canopy diameters.
• Lo-Oil basal bark treatments: For Lo-Oil basal bark treatments, apply STERLING BLUE to the basal
stem region from the ground line to a height of 12 -18". Spray until runoff, with special emphasis on
21
covering the root crown. For best results, apply STERLING BLUE when plants are dormant. Do not
apply after bud break or when plants are showing signs of active growth. Do not apply when snow or
water prevents applying STERLING BLUE to the ground line.
To prepare approximately 2 gallons of a Lo-Oil spray solution:
1. Combine 1.5 gallons of water, 1 ounce of emulsifier, 16 fluid ounces of STERLING BLUE, and 2.5 pints
of No. 2 diesel fuel.
2. Adjust the amounts of materials used proportionately to the amount of final spray solution desired.
Do not exceed 8 gallons of spray solution mix applied per acre, per year.

• Curtail® • Tordon® 22K
. Garlon® • 2,4-D
CONSERVATION RESERVE PROGRAM (CRP)
STERLING BLUE is recommended for use on both newly seeded and established grasses grown in
Conservation Reserve or federal Set-Aside Programs. Treatments of STERLING BLUE will injure or may kill
alfalfa, clovers, lespedeza, wild winter peas, vetch, and other legumes.
NEWLY SEEDED AREAS
STERLING BLUE may be applied either preplant or postemergence to newly seeded grasses or small
grains such as barley, oats, rye, sudangrass, wheat, or other grain species grown as a cover crop.
Postemergence applications may be made after seedling grasses exceed the 3-leaf stage. Rates of
STERLING BLUE greater than 16 fluid ounces per treated acre may severely injure newly seeded grasses.
Preplant applications may injure new seedings if the interval between application and grass planting is
less than 45 days per 16 fluid ounces of STERLING BLUE applied per treated acre west of the Mississippi
River or 20 days per 16 fluid ounces applied east of the Mississippi River.
ESTABLISHED GRASS STANDS
Established grass stands are perennial grasses planted one or more seasons prior to treatment. Certain
species (bentgrass, carpetgrass, smooth brome, buffalograss, or St. Augustinegrass) may be injured
when treated with more than 16 fluid ounces of STERLING BLUE per treated acre.
When applied at specified rates, STERLING BLUE will control many annual and biennial weeds and
provide control or suppression of many perennial weeds.
Rates and Timings
Apply 4-32 fluid ounces of STERLING BLUE per acre. Refer to Table 2 for rates based on target weed
species. STERLING BLUE may be tank mixed or applied sequentially with other products labeled for use in
Conservation Reserve Programs such as atrazine, Cyclone®, glyphosate (Roundup PowerMAX®),
22
Gramoxone Inteon™, Touchdown®, or 2,4-D.
Retreatments may be made as needed; however, do not exceed a total of 64 fluid ounces (4 pints) of
STERLING BLUE per acre per year.
SMALL GRAINS NOT UNDERSEEDED TO LEGUMES
(fall- and spring-seeded barley, oat, triticale and wheat)
STERLING BLUE combinations with listed tank mix partners will provide control or suppression of the
annual broadleaf weeds listed in Table 1. For improved control of listed weeds, tank mix STERLING BLUE
with one or more of the herbicides listed. STERLING BLUE used in a tank mix with other herbicides offers
the best spectrum of weed control and herbicide tolerant or resistant weed management. Refer to the
specific crop section for STERLING BLUE application rate and timing.
For applications prior to weed emergence or when sulfonylurea-resistant weeds are present or suspected,
tank mix a minimum of 3 fluid ounces of STERLING BLUE per treated acre with a non-sulfonylurea
herbicide such as 2,4-D or MCPA. Tank mixing STERLING BLUE with these products will offer more
consistent control of sulfonylurea-resistant weeds.
Additives: When tank mixing STERLING BLUE with sulfonylurea herbicides (Ally®, Amber8, Express®,
Finesse®, Glean®, Harmony® Extra, and Peak®), use 1-4 pints of an agriculturally approved
surfactant (containing at least 80% active ingredient) per 100 gallons of spray or not more than 0.25 -
0.5% by volume. Use the highest rate of surfactant when using the lower rate ranges of the tank mix or
when treating more mature and difficult to control weeds or dense vegetative growth.
Refer to the specific crop sections below for use rates. When treating difficult to control weeds such as
kochia, wild buckwheat, cow cockle, prostrate knotweed, Russian thistle, and prickly lettuce or when
dense vegetative growth occurs, use the 3 - 4 fluid ounces of STERLING BLUE per acre.
Timings: Apply STERLING BLUE before, during, or after planting small grains. See specific small grain
crop uses below for maximum crop stage. For best performance, apply STERLING BLUE when weeds are
in the 2 - 3 leaf stage and rosettes are less than 2" across. Applying STERLING BLUE to small grains dur-
ing periods of rapid growth may result in crop leaning. This condition is temporary and will not reduce
crop yields.
Applications to small grains may be made with aerial applications with 1 gallon of water or more per acre.
Where dense foliage is present, 2 - 3 gallons of water per acre should be used.
Restrictions for small grain areas that are grazed or cut for hay are indicated in Table 6 in Pasture, Hay,
Rangeland, and General Farmstead section of this label.
SMALL GRAINS: BARLEY
(fall- and spring-seeded)
EARLY SEASON APPLICATIONS:
Apply 2-4 fluid ounces of STERLING BLUE to fall-seeded barley prior to the jointing stage. Apply 2-3
fluid ounces of STERLING BLUE before spring-seeded barley exceeds the 4-leaf stage.
Note: For spring barley varieties that are seeded during the winter months or later, follow the rates and
timings given for spring-seeded barley.
Do not tank mix STERLING BLUE with 2,4-D in early season applications on spring-seeded barley.
r
23
PREHARVEST APPLICATIONS:
STERLING BLUE can be used to control weeds that may interfere with harvest of fall- and spring-seeded
barley. Apply 8 fluid ounces of STERLING BLUE per acre as a broadcast or spot treatment to annual
broadleaf weeds when barley is in the hard dough stage and the green color is gone from the nodes
(joints) of the stem. Best results will be obtained if application can be made when weeds are actively
growing, but before weeds canopy.
Pre-harvest Interval (PHI):
A waiting interval of 7 days is required before harvest.
Do not use pre-harvest treated barley for seed unless a germination test is performed on the seed with
an acceptable result of 95% germination or better.
For control of additional broadleaf weeds or grasses, STERLING BLUE may be tank mixed with other
herbicides, such as 2,4-D, that are labeled for pre-harvest uses in barley.
Do not make pre-harvest applications in California.

programs below. Early season applications to fall-seeded wheat must be made prior to the jointing stage.
Early season applications to spring-seeded wheat must be made before wheat exceeds the 6-leaf stage.
Early developing wheat varieties such as TAM 107, Madison, or Wakefield must receive application
between early tillering and the jointing stage. Care should be taken in staging these varieties to be
certain that the application occurs prior to the jointing stage.
To improve control of Russian thistle, flixweed, gromwell, or mayweed, add 2,4-D amine or ester to a
tank mix with one of the following herbicides: Ally®, Amber®, Express®, Finesse®, Glean®, Harmony®
Extra, or Peak®.
SPECIFIC USE PROGRAMS FOR FALL-SEEDED WHEAT ONLY:
STERLING BLUE may be used at 6 fluid ounces on fall-seeded wheat in Western Oregon as a spring
application only. In Colorado, Kansas, New Mexico, Oklahoma, and Texas, up to 8 fluid ounces of
STERLING BLUE may be applied on fall-seeded wheat after it exceeds the 3-leaf stage for suppression of
perennial weeds, such as field bindweed. Applications may be made in the fall following a frost but before
a killing freeze. STERLING BLUE may be tank mixed with 2,4-D amine at 8 fluid ounces after wheat
begins to tiller. Periods of extended stress such as cold and wet weather may enhance the possibility of
crop injury. For fall applications only, do not use if the potential for crop injury is not acceptable.
PREHARVEST APPLICATIONS:
STERLING BLUE can be used to control weeds that may interfere with harvest of wheat. Apply 8 fluid
ounces STERLING BLUE per acre as a broadcast or spot treatment to annual broadleaf weeds when
wheat is in the hard dough stage and the green color is gone from the nodes Q'oints) of the stem. Best

SORGHUM
STERLING BLUE may be applied preplant, postemergence, or preharvest in sorghum to control many
annual broad leaf weeds and to reduce competition from established perennial broadleaf weeds, as well
as control their seedlings.
Do not graze or feed treated sorghum forage or silage prior to mature grain stage. If sorghum is grown
for pasture or hay, refer to Pasture, Hay, Rangeland, and General Farmstead section of this label for
specific grazing and feeding restrictions.
Do not apply STERLING BLUE to sorghum grown for seed production.
Pre-harvest Interval (PHI):
Sorghum, forage PHI = 20 days
Sorghum, fodder PHI = 30 days
PREPLANT APPLICATION:
Up to 8 fluid ounces of STERLING BLUE may be applied per acre if applied at least 15 days before
sorghum planting,
POSTEMERGENCE APPLICATION:
Up to 8 fluid ounces of STERLING BLUE per acre may be applied after sorghum is in the spike stage (all
sorghum emerged) but before sorghum is 15" tall. For best performance, apply STERLING BLUE when
the sorghum crop is in the 3 - 5 leaf stage and weeds are small (less than 3" tall). Use drop pipes (drop
nozzles) if sorghum is taller than 8". Keep the spray off the sorghum leaves and out of the whorl to
reduce the likelihood of crop injury and to improve spray coverage of weed foliage. Applying STERLING
BLUE to sorghum during periods of rapid growth may result in temporary leaning of plants or rolling of
leaves. These effects are usually outgrown within 10-14 days.
Preharvest uses in Texas and Oklahoma only:
Up to 8 fluid ounces of STERLING BLUE per acre may be applied for weed suppression any time after the
sorghum has reached the soft dough stage. An agriculturally approved surfactant may be used to
improve performance. For aerial applications, use at least 2 gallons of water-based carrier per treated
acre. Delay harvest until 30 days after a preharvest treatment.
SPLIT APPLICATION:
STERLING BLUE may be applied in split applications: preplant followed by postemergence or preharvest;
or postemergence followed by preharvest. Do not exceed 8 fluid ounces per acre, per application or a
total of 16 ounces per acre, per season.

soybeans. Do not exceed 16 fluid ounces of STERLING BLUE per acre in a spring application prior to
planting soybeans.
Following application of STERLING BLUE and a minimum accumulation of 1" rainfall or overhead
irrigation, a waiting interval of 14 days is required for 8 fluid ounces per acre or less, and 28 days for 16
fluid ounces per acre. These intervals must be observed prior to planting soybeans or crop injury may
occur.
Do not make STERLING BLUE preplant applications to soybeans in geographic areas with average annual
rainfall less than 25".
PREHARVEST APPLICATIONS:
STERLING BLUE can be used to control many annual and perennial broadleaf weeds and control or
suppress many biennial and perennial broadleaf weeds in soybean prior to harvest (refer to Table 1).
Apply 8 - 32 fluid ounces of STERLING BLUE per acre as a broadcast or spot treatment to emerged and
actively growing weeds after soybean pods have reached mature brown color and at least 75% leaf drop
has occurred.
Pre-harvest Interval (PHI):
Soybeans may be harvested 7 days or more after a pre-harvest application.
Treatments may not kill weeds that develop from seed or underground plant parts, such as rhizomes or
bulblets, after the effective period for STERLING BLUE. For seedling control, a follow-up program or other
cultural practice could be instituted.
Do not use preharvest-treated soybean for seed unless a germination test is performed on the seed with
an acceptable result of 95% germination or better.

atrazine, Evik®, and 2,4-D.
FARMSTEAD TURF (noncropland) and SOD FARMS
For use in general farmstead (noncropland) and sod farms, apply 3 - 32 fluid ounces of STERLING BLUE
per acre to control or suppress growth of many annual, biennial, and some perennial broadleaf weeds
commonly found in turf. STERLING BLUE will also suppress many other listed perennial broadleaf weeds
and woody brush and vine species. Refer to Table 2 for rate specifications based on targeted weed or
brush species and growth stage. Some weed species will require tank mixes for adequate control.
Repeat treatments may be made as needed; however, do not exceed 32 fluid ounces of STERLING BLUE
per acre, per growing season.
Apply 30 - 200 gallons of diluted spray per treated acre (3-17 quarts of water per 1,000 square feet),
depending on density or height of weeds treated and on the type of equipment used.
To avoid injury to newly seeded grasses, delay application of STERLING BLUE until after the second
mowing. Furthermore, applying more than 16 fluid ounces of STERLING BLUE per treated acre may cause
noticeable stunting or discoloration of sensitive grass species such as bentgrass, carpetgrass,
buffalograss, and St. Augustinegrass.
In areas where roots of sensitive plants extend, do not apply more than 4 fluid ounces of STERLING
(
29
BLUE per treated acre on coarse-textured (sandy-type) soils, or in excess of 8 fluid ounces per treated
acre on fine-textured soils.

RIGHTS-OF-WAY, UTILITY AND INDUSTRIAL AREAS, AND FENCEROWS
STERLING BLUE is recommended for use on non-crop land areas such as rights-of-way (such as
roadways, rest areas, utility, railroad, highway, pipeline, and rights-of-way that run through pasture and
rangeland); utility facilities (such as substations, pipelines, tankfarms, pumping stations, parking and
storage areas, fencerows, and non-irrigated ditchbanks); brush control for forest site preparation or
maintenance.
Observe all Precautions on this label. Read and follow the Mixing and Application section.
Rights-of-Way
STERLING BLUE can be used to control many broadleaf weeds on rights-of-way. This use includes
applications to roadside, roadway and highways; to areas along utilities such as cable and powerlines;
railroad track and embankment; highways, highway medians, bridge abutments, pipelines, and rights-of-
way that run through pasture and rangeland. Use controlled application techniques that minimize the risk
of off-target movement.
Utility and Industrial Areas
STERLING BLUE can be used to control many broadleaf weeds and brush in noncrop areas on or
surrounding substations, pipelines, tankfarms, pump stations, production facilities, and bareground
situations. It may also be used on parking and storage areas (refer to Best Stewardship Practices to avoid
direct runoff from impervious surfaces).
Fencerows
STERLING BLUE can be used to control many broadleaf weeds and brush in fencerows.
Mixing and Application
Read and observe Management of Off-Site Movement recommendations in this label.
STERLING BLUE can be applied using water, oil in water emulsions including invert systems, or sprayable
fluid fertilizer as a carrier. A compatibility test (see Compatibility Test section) should be made prior to
30
tank mixing.
To prepare oil in water emulsions, half-fill spray tank with water, then add the appropriate amount of
emulsifier. With continuous agitation, slowly add the herbicide and then the herbicidal oil or a pre-mix of
oil plus additional emulsifier to spray tank. Complete filling of spray tank with water. Maintain vigorous
agitation during spray operation to prevent oil and water from forming separate layers.
STERLING BLUE may be applied broadcast using either ground or aerial application equipment. When
using ground equipment, apply low or high volume sprays of between 3 - 600 gals, of diluted spray per
treated acre. Volume of spray applied will depend OR the height, density, and type of weeds or brush
being treated and on the type of equipment being used. When using aerial equipment, apply 5-40 gals,
of diluted spray per treated acre.
STERLING BLUE may be applied to individual clumps or small areas (spot treatment) of undesirable
vegetation using handgun or similar types of application equipment. Apply diluted sprays to allow
complete wetting (up to runoff) of foliage and stems.
Herbicide adjuvants or other spray additives (emulsifiers, spreader stickers, surfactants, wetting agents,
drift control agents, or penetrants) may be used for wetting, penetration, or drift control. Spray additives
must be agriculturally approved when used in pasture applications. If spray additives are used, read and
follow all use recommendations and precautions on product label.
Weeds and Brush Controlled
STERLING BLUE, when applied at specified rates, will give control of many annual, biennial, and perennial
broadleaf weeds, and many woody brush and vine species commonly found in non-crop land areas.
(Refer to General Weed List.) Noted (*) perennial weeds may be controlled with lower rates of either
STERLING BLUE or STERLING BLUE plus tank mix combinations. See Rates and Timings below.

FOREST SITE PREPARATION
Product Information
STERLING BLUE may be used for control of undesirable conifers as well as many broadleaf weeds, vines,
brambles, hardwood brush, and trees in forest site preparation. STERLING BLUE may be applied as
broadcast foliar sprays from ground or aerial equipment. STERLING BLUE is absorbed through the leaf
surfaces quickly after spraying and will also be absorbed from the soil by the roots. Translocation through
the leaves, stems, and roots provides control of undesirable young conifer and broadleaf species. Woody
plants, brush, and trees may not display the full extent of herbicide efficacy until several months fol-
lowing treatment. STERLING BLUE provides application flexibility for extended windows of application and
tank mix options (refer to Mixing and Application Procedures and Tank Mix Options).
Mixing and Application Instructions
Ground Operated Spray Equipment
Thoroughly mix and apply the listed rate of STERLING BLUE (2 pints/A maximum) in a minimum of 15
gals, of water per acre. Spray solution should uniformly cover undesirable foliage for best results. A
suitable nonionic surfactant should be added to the spray solution to enhance foliage wetting, spreading,
and solution absorption. Drift control and foam reducing agents may be added at specified rates, if
needed. Spray pattern indicator agents may also be added at specified rates, if desired. Do not spray
under windy or gusty conditions. Maintain proper buffer zones to ensure drift does not reach off-target
vegetation.
Aerial Spray Equipment
Thoroughly mix the listed rate of STERLING BLUE (2 pints/A maximum) in a minimum of 10 gals, of
water per acre and uniformly apply with properly calibrated aerial equipment. A suitable nonionic
surfactant should be added to the spray solution to enhance wetting, spreading, and solution absorption.
All precautions should be taken to minimize or eliminate spray drift. Drift control and foam control agents
may be added at specified rates, if needed.
Tank Mix Options
For extended range of species control, tank mix STERLING BLUE with other forest site preparation
products such as Arsenal, Garlon, Accord, etc. Observe all precautions and restrictions on the product
labels. Always follow the most restrictive label in a tank mix.
TURF AND LAWNS
Including Golf Course (Fairways, Aprons, Tees, and Rough), Parks, Recreational Areas and Lawn Care
application.
IMPORTANT: Observe all Precautions on this label. Read and follow Mixing and Application Procedures.
Established grass stands growing under stress can exhibit various injury symptoms that may be more
pronounced if herbicides are applied. To avoid injury to newly seeded grasses, application of STERLING
BLUE should be delayed until after the second mowing. Furthermore, application rates in excess of 1 pt.
(1/2 Ib. a.i.) per treated acre may cause noticeable stunting or discoloration of sensitive grass species
such as bentgrass, carpetgrass, buffalograss, and St. Augustine grass.
In areas where roots of sensitive plants extend, do not apply in excess of 1/4 pt. (1/8 Ib. a.i.) of STERLING
BLUE per treated acre on coarse-textured (sandy-type) soils, or in excess of 1/2 pt. (1/4 Ib. a.i.) per
33
treated acre on fine-textured (clay-type) soils. Do not make repeat applications in these areas for 30 days
and until previous applications of STERLING BLUE have been activated in the soil by rain or irrigation.
Weeds Controlled
STERLING BLUE, when applied at specified rates, will give control of many annual, biennial, and noted
(*) perennial broadleaf weeds commonly found in turf. STERLING BLUE will also give growth suppression
of many other listed perennial broadleaf weeds and woody brush and vine species. (Refer to General
Weed List.)
Mixing and Application
Apply 30-200 gals, of diluted spray per treated acre (3 - 17 qts. of dilution/1,000 sq. ft.), depending on
density or height of weeds treated and on the type of equipment used.
