GENERAL INFORMATION 
The following directions apply to all uses of Sterling. Additional precautions and 
restrictions will appear in each specific use section. 
Do not treat irrigation ditches or water used for crop irrigation or domestic purposes. 
Do not apply this product through any type of irrigation system. 
MIXING AND APPLICATION 
UNLESS OTHERWISE SPECIFIED UNDER THE INDIVIDUAL USE HEADINGS OF 
THIS LABEL, THE FOLLOWING DIRECTIONS APPLY TO ALL CROP AND NON­
CROP USES OF STERLING. REFER TO INDIVIDUAL USE SECTIONS FOR 
ADDITIONAL PRECAUTIONS, RESTRICTIONS, APPLICATION RATES, AND 
TIMINGS. 
Sterling is a water soluble formulation that can be applied using water or sprayable fluid 
fertilizer as the carrier. If a fluid fertilizer is used, a compatibility test (see below) should 
be made prior to tank mixing. 
When an adjuvant is to be used with this product, Winfield Solutions, LLC recommends 
the use of a Chemical Producers and Distributors Association certified adjuvant. 
Ground or aerial equipment which will provide good spray coverage of weed foliage 
should be used. DO NOT USE AERIAL APPLICATION EQUIPMENT IF SPRAY 
PARTICLES CAN BE CARRIED BY WIND INTO AREAS WHERE SENSITIVE CROPS 
OR PLANTS ARE GROWING, OR WHEN TEMPERATURE INVERSION CONDITIONS 
EXIST. 
5 
Apply 3 to 50 gallons of spray dilution per acre when using ground application 
equipment. For aerial application, apply 1 to 10 gallons per acre for weed control or 2 to 
20 gallons per acre for preharvest uses. Use the higher volumes when treating dense or 
tall vegetation. 
Apply as a coarse spray. Select nozzles designed to produce minimal amounts of fine 
spray particles. Spray with nozzles as close to weeds as practical for good coverage. 
To avoid uneven spray coverage, do not apply during periods of gusty winds, or when 
wind is in excess of 15 miles per hour. 
Avoid disturbing (e.g. cultivating or mowing) sprayed areas for at least 7 days after 
application. 
SPRAY DRIFT MANAGEMENT 
AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF 
THE APPLICATOR. The interaction of many equipment-and-weather-related factors 
determine the potential for spray drift. The applicator and the grower are responsible for 
considering all these factors when making decisions. 
The following drift management requirements must be followed to avoid off-target 
movement from aerial applications to agricultural field crops. These requirements do not 
apply to forestry applications, public health uses or to applications using dry 
formulations.

1. The distance of the outer most nozzles on the boom must not exceed 3/4 the length of 
the wingspan or rotor. 
2. Nozzles must always point backward parallel with the air stream and never be pointed 
downwards more than 45 degrees. 
Where states have more stringent regulations, they must be observed. 
The applicator must be familiar with and take into account the information covered in the 
Aerial Drift Reduction Advisory. 
Drift Reduction Advisory 
Information on Droplet Size 
The most effective way to reduce drift potential is to apply large droplets. The best drift 
management strategy is to apply the largest droplets that provide sufficient coverage 
and control. Applying larger droplets reduces drift potential, but will not prevent drift if 
applications are made improperly, or under unfavorable environmental conditions (See 
"Wind", "Temperature and Humidity", and "Temperature Inversions"). 
Controlling Droplet Size 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. 
Nozzles with higher rated flows produce larger droplets. 
• Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For 
many nozzle types lower pressure produces larger droplets. When higher flow rates 
are needed, use higher flow rate nozzles instead of increasing pressure. 
• Number of nozzles - Use the minimum number of nozzles that provide uniform 
coverage. 
• Nozzle Orientation - Orienting nozzles so that the spray is released backwards, 
parallel to the airstream produces larger droplets than other orientations and is the 
recommended practice. Significant deflection from horizontal will reduce droplet size 
and increase drift potential. 
• Nozzle Type - Use a nozzle type that is designed for the intended application. With 
most nozzle types, narrower spray angles produce larger droplets. Consider using 
low-drift nozzles. Solid stream nozzles oriented straight back produce the largest 
droplets and the lowest drift. 
Boom Length 
For some use patterns, reducing the effective boom length to less than 3/4 of the 
wingspan or rotor length may further reduce drift without reducing swath width. 
Application Height 
Applications must not be made at a height greater than 10 feet above the top of the 
target plants unless a greater height is required for aircraft safety. Making applications 
at the lowest height that is safe reduces exposure of droplets to evaporation and wind. 
Swath Adjustment 
When applications are made with a crosswind, the swath will be displaced downwind. 
Therefore, on the up and downwind edges of the field, the applicator must compensate 
for this displacement by adjusting the path of the aircraft upwind. Swath adjustment 
distance should increase with increasing drift potential (higher wind, smaller drops, etc.) 
Wind 
Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, 
including droplet size and equipment type determine drift potential at any given speed. 
Application should be avoided below 2 mph due to variable wind direction and high

inversion potential. NOTE: Local terr '. . 
should be familiar with local wind patt am cand,nhfluence wind patterns. ~very applicator 
Temperature and Humidity 
erns an ow they affect spray drrft. 
When making applications in low relative humidity, set up equipment to produce larger 
droplets to compensate for evaporation. Droplet evaporation is most severe when 
conditions are both hot and dry. 
Temperature Inversions 
Applications must not occur during a temperature inversion because drift potential is 
high. Temperature inversions restrict vertical air mixing, which causes small suspended 
droplets to remain in a concentrated cloud. This cloud can move in unpredictable 
directions due to the light variable winds common during inversions. Temperature 
inversions are characterized by increasing temperatures with altitude and are common 
on nights with limited cloud cover and light to no wind. They begin to form as the sun 
sets and often continue into the morning. Their presence can be indicated by ground 
fog; however, if fog is not present, inversions can also be identified by the movement of 
smoke from a ground source or an aircraft smoke generator. Smoke that layers and 
moves laterally in a concentrated cloud (under low wind conditions) indicates an 
inversion, while smoke that moves upward and rapidly dissipates indicates good vertical 
air mixing. 
Sensitive Areas 
The pesticide must only be applied when the potential for drift to adjacent sensitive 
areas (e.g. residential areas, bodies of water, known habitat for threatened or 
endangered species, non-target crops) is minimal (e.g. when wind is blowing away from 
the sensitive areas). 
BEST STEWARDSHIP PRACTICES 
Sterling provides effective broadleaf weed and brush control when properly applied. 
Best stewardship practices in all mixing, loading, and application operations will not only 
maximize weed control, but also protect ground and surface water, and minimize off­
target movement. 
This chemical is known to leach through soil into groundwater under certain conditions 
as a result of agricultural use. Use of this chemical where soils are permeable, 
particularly where the water table is shallow, may result in groundwater contamination. 
GROUND AND SURFACE WATERS PROTECTION 
1) Point source contamination: To prevent pOint-source contamination, do not mix and 
load this pesticide product within 50 feet of wells (including abandoned wells and 
drainage wells), sink holes, perennial or intermittent streams or rivers, or natural or 
impounded lakes or 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 pads 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% of 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 
7

8 
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 with 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 anti-siphoning devices must be used on all mixing 
equipment. 
2) Movement by 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 groundwater contamination. 
Groundwater contamination may occur in areas where soils are permeable or coarse 
and groundwater is near the surface. Do not apply to soils classified as sand with 
less than 3% organic matter and where groundwater depth is shallow (less than 8 
feet in Arizona). To minimize the possibility of groundwater contamination, carefully 
follow application rate recommendations as affected by soil type in the "GENERAL 
INFORMATION" section of this label. 
3) Movement by water erosion treated soil: Do not apply nor incorporate this product 
through any type of irrigation equipment, nor by flood or furrow irrigation. Ensure 
treated areas have received at least % inch of rainfall or irrigation before using 
tailwater for subsequent irrigation of other fields. 
SENSITIVE CROP PRECAUTIONS 
Sterling may cause injury to desirable trees and plants, particularly beans, cotton, 
flowers, fruit trees, grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, 
tomatoes, and other broad leaf plants when contacting their roots, stems, or foliage. 
These plants are most sensitive to Sterling during their development or growing stages. 
FOLLOW THE PRECAUTIONS LISTED BELOW WHEN USING STERLING: 
Do not treat areas where either possible downward movement into the soil or surface 
washing may cause contact of Sterling with the roots of desirable plants such as 
trees and shrubs. 
Avoid making applications when spray particles may be carried by air currents to 
areas where sensitive crops and plants are growing, or where temperature 
inversions exist. Do not spray near sensitive plants if wind is gusty or greater than 5 
miles per hour, and moving in the direction of adjacent sensitive crops. Leave an 
adequate buffer zone between area to be treated and sensitive plants. Coarse 
sprays are less likely to drift out of the target area than fine sprays. 
Use coarse sprays to avoid potential herbicide drift. Select nozzles which are 
designed to produce minimal amounts of fine spray particles. Examples of nozzles 
designed to produce coarse sprays via ground application are Delavan RaindropsTM, 
Spraying Systems XRTM flat fans, or large-capacity flood nozzles such as 010, TK10, 
or greater capacity tips. Keep the spray pressure at or below 20 PSI, and the spray 
volume at or above 20 gpa unless otherwise directed by the manufacturer of the 
nozzles. Consult your spray-nozzle supplier about the choice of drift reducing 
nozzles. 
Agriculturally-approved drift-reducing additives may be used. 
/0 
sY

9 
Do not apply Sterling adjacent to sensitive crops when the temperature on the day of 
application is expected to exceed 85° F, since drift will be more likely to occur. 
To avoid injury to desirable plants, equipment used to apply Sterling must be 
thoroughly cleaned (See "PROCEDURE FOR CLEANING SPRAY EQUIPMENT") 
before re-using to apply any other chemicals. 
All crop uses of Sterling are intended for a normal growing interval between planting and 
harvest. No crop rotation restrictions exist if normal harvest of treated crops has 
occurred. If this interval is shortened, such as in cover crops that will be plowed under, 
do not follow up with the planting of a sensitive crop. 
Crops growing under stress conditions such as drought, poor fertility, or foliar damage 
due to hail, wind, or insects can display various injury symptoms that may be more 
pronounced if herbicides are applied. 
Consult your local or State authorities for possible application restrictions and advice 
concerning these and other special local use situations. Tank mix recommendations are 
for use only in those states where the tank mix product and application site are 
registered.

The steps listed below are suggested for thorough cleaning of spray equipment following 
application of Sterling or tank mixes with Sterling and 2,4-D Amine. 
1) Thoroughly hose down the inside and outside surfaces of the equipment while filling 
the spray tank 112 full with water. Activate the sprayer and spray until the rinse water is 
completely flushed out. 
2) Fill the tank with water while adding 1 quart of household ammonia per 25 gallons of 
water. Operate the pump to circulate the ammonia solution through the sprayer system 
for 15 to 20 minutes, and discharge a small amount of the ammonia solution through the 
boom and nozzles. Let the solution stand for several hours, preferably overnight. 
3) Flush the solution out through the boom. 
4) Remove nozzles and screens and flush through 2 tanks full of water. 
If Sterling is tank-mixed with wettable powders (WP), emulsifiable concentrates (EC) or 
other types of water-dispersible formulations, follow the cleaning steps below: 
5) Complete step 1 above. 
6) Fill tank with water while adding 2 pounds of detergent per 40 gallons of water. 
Operate the pump to circulate the detergent solution through the sprayer system for 5 to 
10 minutes, and discharge a small amount through the boom and nozzles. Let the 
solution stand for several hours, preferably overnight. 
7) Flush the detergent solution out through the boom.

Sterling is a Group 4 Herbicide containing the active ingredient dicamba. The 
continuous use of this product and chemically related products may cause the 
development of biotypes of grasses and broad leaf weeds that cannot be effectively 
controlled by this and related herbicides. Where this is known or suspected and weeds 
controlled by this product are expected to be present along with resistant biotypes, we 
recommend the use of this product in combinations or in sequence with other registered 
herbicides which are not solely a Group 4 Herbicide. If only resistant biotypes are 
expected to be present, use a registered herbicide which is not solely a Group 4 
Herbicide. Consult your state Extension Service for specific recommendations for you.r

CORN (FIELD, SEED, POPCORN, SILAGE) 
NOT FOR USE ON SEED CORN AND POPCORN IN CALIFORNIA. 
SOME SENSITIVE VARIETIES OF SEED CORN AND POPCORN MAY BE INJURED 
BY TREATMENT WITH STERLING OR OTHER BRANDS OF DICAMBA. VERIFY 
WITH YOUR SEED SUPPLIER THE DICAMBA SELECTIVITY VARIETY OF SEED 
CORN OR POPCORN BEFORE APPLICATION. STERLING IS NOT REGISTERED 
FOR USE ON SWEET CORN. 
Observe precautions, mixing, and application instructions on this label, plus the 
following: 
13 
- Direct contact of Sterling with corn seed must be avoided. If corn seeds are less than 
1 1/2 inches below the surface, delay application until corn has emerged. 
- Up to 2 applications of Sterling may be made during a growing season. Do not exceed 
a total of 1 1/2 pints of Sterling (including equivalent amount of other dicamba products) 
per treated acre per crop year. Allow 2 weeks or more between applications of Sterling. 
- Applications of Sterling to corn during periods of rapid growth may result in temporary 
leaning. Corn will usually become erect again within 3 to 7 days. Cultivation should be 
delayed until corn is growing normally to avoid breakage. 
- Agriculturally approved surfactants or sprayable fluid fertilizers (112 to 1 gallon per acre 
of 28%, 30%, or 32% urea ammonium nitrate, or 2.5 pounds per acre spray-grade 
ammonium sulfate) may be added to the spray mixture to improve post-emergence 
weed control, particularly in dry conditions. 
- Do not use adjuvants containing penetrants such as petroleum-based oils after crop 
emergence, since crop injury may result. 
- Corn may be harvested or grazed for feed once the crop has reached the ensilage 
(milk) stage, or later. 
Some synthetic pyrethroid insecticides may be tank mixed with Sterling. Refer to the 
labels of the insecticide products for specific directions. 
Weeds Controlled 
Sterling will control many annual broadleaf weeds, and suppress growth of many 
perennial weeds in corn (see general weed list). 
For best performance, apply when weeds have emerged and are actively growing. Pre­
emergence control of cocklebur, velvetleaf, and jimsonweed may be reduced if 
conditions such as low temperature or lack of soil moisture cause delayed or deep 
germination of weeds. 
No-Tillage Corn 
Applications of Sterling may be made before, during, or after planting to emerged and 
actively growing weeds. Apply 1 pint of Sterling per acre on medium or fine-textured 
soils containing 2% or greater organic matter. Use 1/2 pint per acre on coarse textured 
soils such as sand, sandy loam, or loamy sand, or on medium textured soils with less

than 2% organic matter. When planting into a legume sod such as alfalfa or clover, 
apply Sterling after 4 to 6 inches of regrowth has occurred. 
Conventional or Reduced-Tillage Corn 
Sterling may be applied after planting and prior to emergence of corn. In fine or 
medium-textured soils which contain 2% or more organic matter, use 1 pint per acre. 
14 
DO NOT APPLY to coarse-textured soils (sand, sandy loam, loamy sand) until after crop 
emergence - see "CORN, EARLY POST-EMERGENCE" below. Pre-emergence 
application of Sterling does not require mechanical incorporation to be 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 or harrows) which 
concentrate treated soil over furrows. 
Corn, Early Post-Emergence 
(Spike through 8 inches tall) 
Sterling may be applied at a rate of 1 pint per acre during the period from corn 
emergence through 5-leaf stage, or 8 inches tall, whichever comes first. Reduce the 
rate to 1/2 pint per acre if corn is growing in coarse textured soils (sand, sandy loam, 
loamy sand). If the 6th true leaf is emerging from the whorl, or if the corn is greater than 
8 inches tall, see "CORN, LATE POST-EMERGENCE" directions below. 
Corn, Late Post-Emergence 
(8 to 36 inches tall) 
Sterling may be applied at a rate of 1/2 pint per acre when corn is between 8 and 36 
inches tall, or 15 days before tassel emergence, whichever comes first. For best results, 
apply when weeds are less than 3 inches tall. 
A directed spray application should be made if 1) corn leaves prevent adequate spray 
coverage, 2) sensitive crops are growing nearby, or 3) Sterling is tank-mixed with 2,4-0. 
DO NOT APPLY Sterling when soybeans are growing nearby if any of the following 
conditions exist: 1) Corn is more than 24 inches tall, 2) soybeans are more than 10 
inches tall, or 3) soybeans have begun to bloom. 
Sequential Treatments 
Sterling may be applied to ground previously treated with one or more of the following 
herbicides registered for use in corn: 
Acetochlor Glyphosate 
Alachlor Halosulfuron 
Atrazine Metolachlor 
Diglycolamine salt of dicamba Paraquat 
Dimethenamid Pendimethalin 
EPTC Simazine 
READ AND FOLLOW ALL LABEL DIRECTIONS FOR THE LISTED PRODUCTS. 
Tank Mix Treatments For Corn 
Sterling may be tank-mixed with one or more of the following herbicides for control of 
grasses or additional broadleaf weeds. READ AND FOLLOW ALL LABEL 
RESTRICTIONS AND LIMITATIONS AND DIRECTIONS FOR THE LISTED TANK MIX 
PRODUCTS.

SORGHUM (MILO) 
Observe precautions, mixing, and application instructions on this label. 
- If sorghum is used for grain, forage or fodder, the following restrictions apply: 
3D-day PHI for grain 
2D-day PHI for forage 
3D-day PHI for fodder 
15 
- Applications of Sterling to sorghum during periods of rapid growth may result in 
temporary leaning of plants or rolling of leaves. These effects are usually outgrown in 1 D 
to 14 days. 
- 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 the PASTURE, HAY, RANGELAND AND 
FARMSTEAD section of this label. 
- Make no more than 1 application per growing season. 
Weeds Controlled 
Sterling applied at the indicated rate for grain sorghum will control many actively growing 
annual broad leaf weeds and will reduce competition from established perennial 
broad leaf weeds as well as control their seedlings. (see GENERAL WEED LIST) 
Rates And Timings 
Sterling may be applied to emerged and actively growing weeds at least 15 days prior to 
planting. Post-emergence application of Sterling must be made after sorghum is in the 
spike stage (all sorghum emerged) but before sorghum is 15 inches tall. For best 
performance, make applications when sorghum is in the 3 to 5 leaf stage and weeds are 
small (less than 3 inches tall.) Use drop nozzles if sorghum is taller than 8 inches. 
Keeping the spray off the sorghum leaves and out of the whorl will reduce the likelihood 
of crop injury and improve spray coverage of the weeds. 
Broadcast Rate Per Treated Area 
Use 112 pint (114 Ib ai) per acre. 
Tank Mixes For Sorghum 
Sterling + Atrazine: 
For improved control of emerged, actively growing broadleaf weeds including triazine­
resistant varieties, and for added suppression of perennial broadleaf weeds, tank-mix 
1/2 pint of Sterling with 1/2 to 1 1/4 Ib ai atrazine per acre. For control of grasses less 
than 1 1/2 inches tall tank mix 1/2 pint of Sterling with 2 Ib ai atrazine per acre. For best 
performance and minimum crop injury make the application when the sorghum is 3 to 8 
inches tall and when broad leaf weeds are less than 6 inches tall. Application of atrazine 
n --3'-'

must be made before sorghum is greater than 12 inches tall. The rate of atrazine will 
depend on soil texture and length of residual control desired. Follow all State and 
Federal restrictions pertaining to atrazine application. 
Sterling plus Bromoxynil: 
For improved control of broad leaf weeds, tank mix 1/2 pint Sterling with 1 to 1 1/2 pint 
bromoxynil per treated acre. Make application at the 4 leaf to 15 inch tall sorghum 
stages. Use drop nozzles to direct spray beneath sorghum leaves when sorghum is 
greater than 8 inches tall. 
Sequential Treatments 
Sterling may be applied to ground previously treated with one or more of the following 
herbicides registered for use in sorghum: 
alachlor (safener-treated seed) 
atrazine 
metolachlor (safener-treated seed) 
Preharvest Uses 
FOR USE ONLY IN TEXAS AND OKLAHOMA 
Sterling may be applied for weed suppression any time after 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 
acre. Delay harvest until 30 days after treatment. 
Broadcast rate per acre: 1/2 pint (1/4 Ib ai). 
SMALL GRAINS (WHEAT, BARLEY, OATS) 
(Not Underseeded To Legumes) 
Observe precautions, mixing, and application instructions on this label, plus the 
following: 
Make no more than 2 applications per year. 
If wheat, barley, or oats are to be used for grain, do not harvest treated areas before 7 
days after treatment. 
If small grains are used for pasture or hay, 
- Animals may not be removed from treated areas for slaughter prior to 30 days after 
last application. 
- There is no waiting period between treatment and grazing for non-lactating dairy 
animals. 
- Treated areas may not be grazed by lactating dairy animals before 7 days after 
treatment. 
- Do not harvest hay from treated areas before 37 days after treatment. 
Weeds Controlled 
Sterling alone or in combination with tank mix partners as listed will control or suppress 
the broad leaf weeds listed below in small grains. For improved control of listed weeds, 
Sterling should be applied in tank mixture with other herbicides. Refer to specific crop 
instructions for tank mix options.

Rates And Timing 
17 
Application of Sterling may be made before, after, or during planting of small grains. For 
best performance, make applications when weeds are in the 2 to 3 leaf stage, and 
rosettes are less than 2 inches wide. Application of Sterling to small grains during 
periods of rapid growth may result in crop leaning. This condition is temporary and will 
not affect crop yields. 
Use Sterling at a rate of 4 fl. oz. per treated acre in wheat, fall-seeded barley, and oats, 
and at a rate of 2 to 3 fl. oz. per acre in spring-seeded barley. Use the higher rates when 
treating difficult-to-control weeds such as kochia, wild buckwheat, cow cockle, prostrate 
knotweed, Russian thistle, and prickly lettuce, or if dense vegetative growth is present. 
Fall And Spring Seeded Wheat 
STERLING MUST BE APPLIED TO FALL-SEEDED WHEAT PRIOR TO THE JOINTING 
STAGE. APPLICATIONS TO SPRING-SEEDED WHEAT MUST BE MADE BEFORE 
WHEAT REACHES THE 6-LEAF STAGE. 
Tank Mix Treatments 
Sterling used in a tank-mix with other herbicides provides the best spectrum of weed 
control and herbicide-tolerant or -resistant weed management.

18 
For applications prior to the emergence of weeds, or when sulfonylurea-resistant weeds 
are present or suspected, use a minimum of 3 fluid ounces per acre of Sterling with a 
tank-mix herbicide. Non-sulfonylurea herbicides such as 2,4-0 or MCPA tank-mixed 
with Sterling will offer more consistent control of sulfonylurea-resistant weeds. 
Sterling or combinations with listed tank mix partners will control or suppress the annual 
broad leaf weeds indicated in the GENERAL WEEDS LIST and those listed below for 
specific tank mixtures. Read and follow the most restrictive use directions on the label of 
each tank mix partner listed. 
Broadcast rate per acre 1. Apply Sterling at a rate of 2-4 fluid ounces/acre with one of the 
following tank mix products: 
2,4-0 amine or ester MCPA amine or ester 
Bromoxynil Metribuzin
2 
Chlorsulfuron Metsulfuron-methyl 
Chlorsulfuron + metsulfuron-methyl Triasulfuron 
Clopyralid Thifensulfuron + tribenuron-methyl 
Diuron2 
1 
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. 
2Tank mixtures for fall seeded wheat only. 
Special Use Tank Mixes For Spring And Fall Seeded Wheat 
Apply Sterling at a rate of 3-41 fluid ounces/acre plus one or more of the following: 
2,4-0 amine or ester

Sterling may be used at 6 fluid ounces on fall seeded wheat In western Oregon as a 
spring application only. In CO, KS, NM, OK and TX up to 8 fluid ounces of Sterling 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 fall following a 
frost but before a killing freeze. Sterling may be tank mixed with 2,4-0 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. 
2NOTE: For use on Fall Seeded Wheat Only. Do not use unless potential crop injury 
will be acceptable. 
3Sterling may be applied at 2 fluid ounces with any glyphosate formulation labeled for 
use as a preplant application to small grains with no waiting period prior to planting. 
Read and follow label directions of the tank mix product for adjuvant use 
recommendations.

Observe precautions, mixing, and application instructions on this label, plus the 
following: 
- Do not harvest until 87 days after treatment. 
- Consult your local or State authorities for possible application restrictions, especially 
concerning aerial applications, and for advice concerning special local need situations.

20 
- Application over the top of actively growing sugarcane may result in crop injury. When 
possible, direct the spray beneath the sugarcane canopy to minimize this possibility. 
The use of directed sprays will also maximize spray coverage of the weeds. 
- Maximum single application rate: 1 qtiacre (1 lb. ai/A) and no more than 2 applications 
per year. 
Weeds Controlled 
Sterling applied at the indicated rates for sugarcane will control many actively growing 
annual, biennial, and perennial broadleaf weeds. (see GENERAL WEED LIST). 
Rates And Timings 
Sterling may be applied to emerged and actively growing weeds before the close-in 
stage of sugarcane. Application rates and timing of applications is shown below. Use 
the higher rates when treating dense vegetative growth.

*Application of Sterling plus 2,4-0 at the higher rate ranges may result in crop injury. 
PASTURE, HAY, RANGELAND AND GENERAL FARMSTEAD (Non-cropland) 
Sterling may be used for control of broad leaf and woody weeds (see GENERAL WEED 
LIST) in pasture, hay, rangeland, and general farmstead (non-crop) such as fencerows 
and non-irrigation ditchbanks. Pasture uses include small grains such as wheat, barley, 
forage sorghum, oats, rye, or sudangrass grown only as pasture. Sterling may also be 
applied in non-cropland areas for control of broadleaf weeds in Noxious Weed Control 
Programs, Districts, or Areas including broadcast or spot treatment of roadsides and 
highways, utilities, railroads, or pipeline rights-of-way. Noxious weeds must be 
recognized by the State, but programs may be administered at State, County, or other 
level. 
Observe precautions, mixing, and application instructions on this label, plus the 
following: 
- Do not harvest prior to 7 days after treatment.

21 
- Newly seeded areas, including small grains grown for pasture, may be severely injured 
if rates of Sterling greater than 1 pint per acre are applied. 
- Established grass crops growing under stress conditions may exhibit various 
symptoms of injury that may be more pronounced if herbicides are applied. 
- Bentgrass, carpetgrass, buffalograss, and St. Augustine grass may be injured at rates 
exceeding 1 pint (1/2 Ib ai) per acre of Sterling. Colonial bentgrasses are more tolerant 
than creeping types. Velvetgrasses are most sensitive. Treatments will kill or injure 
alfalfa, clover, lespedeza, wild winter peas, vetch, and other legumes. 
- DO NOT REMOVE ANIMALS FOR SLAUGHTER FROM TREATED AREAS PRIOR 
TO AT LEAST 30 DAYS AFTER THE LAST APPLICATION OF STERLING. SEE 
RESTRICTIONS BELOW FOR LACTATING DAIRY ANIMALS FOLLOWING 
TREATMENT.

Maximum single application rate: 1 qtiacre (1 lb. ai/A) and no more than 2 applications 
per year. 
There is no waiting period between treatment and grazing for non-lactating animals. 
Mixing and Application 
Sterling may be applied using water, oil-in-water emulsions including an invert system, 
or sprayable fluid fertilizer as a carrier. A compatibility test (see COMPATIBILITY rEST 
section above) should be done prior to mixing. 
To prepare an oil-in-water emulsion, half-fill the spray tank with water, then add an 
appropriate emulsifier. While continuously agitating, slowly add the herbicide, then the 
oil, or a premix of oil plus emulsifier to the tank. Complete filling of the tank with water. 
Maintain vigorous agitation during the spraying operation to prevent separation into 
layers. 
Sterling may be broadcast using ground or aerial equipment. When using ground 
equipment, apply 3 to 600 gallons of spray mixture per acre. Volume applied will 
depend on the height, density, and type of weeds or brush being treated, and on the 
equipment used. When using aerial equipment, apply 2 to 40 gallons of spray mixture 
per acre in a water-based carrier. 
Sterling may be applied to individual clumps or small areas of undesirable vegetation 
using handgun or similar equipment. Apply in a dilute spray to allow complete wetting 
(up to run-off) of foliage and stems. 
Adjuvants (emulsifiers, surfactants, wetting agents, drift control agents, penetrants) may 
be used to enhance performance or control drift. Spray additives must be agriculturally 
approved when used in pasture. Follow all directions on the adjuvant label.

22 
Weeds Controlled 
Sterling applied at the indicated rates will control many actively growing annual, biennial, 
and perennial broadleaf weeds, and many woody brush and vine weeds commonly 
found in pasture, hay, rangeland, and general farmstead (non-crop) areas (see

mix treatments for adequate control. 
Tank Mix Treatments for Pasture, Hay, Rangeland and General Farmstead 
Sterling may be tank-mixed with one or more of the following herbicides for control of 
grasses or additional broad leaf weeds. Read and follow the label of each tank mix 
product for precautions, directions for use, rates and timings, weeds controlled, and any 
other restrictions. Due to variations which may occur in formulated products and other 
ingredients (e.g. water supply), a compatibility test (see appropriate section of this label) 
is recommended prior to actual tank mixing. 
2,4-0 
Glyphosate 
Metsulfuron-methyl 
Paraquat 
Picloram 
Triclopyr

23 
CUT SURFACE TREE TREATMENTS 
Sterling may be applied as a cut-surface treatment for control of unwanted trees and 
prevention of sprouts of cut trees. Use a mixture of 1 part Sterling with 1 to 3 parts 
water. Use the higher concentration when treating difficult-to-control species. For more 
rapid effects, 2,4-0 may be added to the mixture. 
FRILL OR GIRDLE TREATMENT: Make a continuous cut or a series of overlapping 
cuts using an axe to girdle the tree trunk. Spray or paint the cut surface with the 
Sterling! water mixture. 
STUMP TREATMENTS: 
Spray or paint the freshly-cut surface with the Sterlingl water mixture. The area adjacent 
to the bark must be thoroughly wet. 
DORMANT APPLICATION FOR MULTIFLORA ROSE 
Sterling may be applied when plants are dormant as an undiluted spot-concentrate 
directly to the sailor as a la-oil basal bark treatment using an oil-water emulsion solution. 
Spot-concentrate applications of Sterling should be made directly to the soil as close as 
possible to the root crown (at least within 6 - 8 inches of the crown). On sloping terrain, 
apply on the uphill side of the crown. Do not make the application when snow or water 
prevents applying directly to soil. The rate is dependent on the canopy diameter. The 
following table may be used as an example. DO NOT EXCEED A TOTAL OF 2 
QUARTS PER ACRE PER GROWING SEASON. 
Canopy diameter Rate 
5 feet 1!4 fl. oz. 
10 feet 1 fl. oz. 
15 feet 2 1!4 fl. oz. 
Lo-oil basal bark applications 
To prepare an oil-in-water emulsion, half-fill the spray tank with water, then add an 
appropriate emulsifier. While continuously agitating, slowly add the herbicide, then the 
oil, or a premix of oil plus emulsifier to the tank. A recommended mixture per gallon of 
spray dilution is 1/2 pint Sterling plus 1/2 ounce emulsifier plus 1 1/4 ounces No.2 
Diesel fuel in water to make 1 gallon total. Maintain vigorous agitation during the 
spraying operation to prevent separation into layers. 
For best results, apply 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 prevent 
application to the ground line. Apply to the basal stem region from the ground line up to 
a height of 12 to 18 inches. Spray until runoff, being sure to thoroughly cover the root 
crown. 
Do not exceed 4 pints of Sterling (2 lb. ai) per acre per growing season. 
CONSERVATION RESERVE PROGRAM (CRP) ACRES 
Sterling is recommended for use on both newly-seeded and established grasses grown 
in conservation reserve (eRP) or Federal set-aside acres. 
Observe precautions, mixing, and application instructions on this label, plus the 
. following: 
- Sterling treatment will injure and may kill alfalfa, clovers, lespedeza, wild winter peas, 
vetch, and other legumes. 
- Agriculturally-approved surfactants may be added to the spray mixture to improve 
post-emergence weed control, particularly in dry growing conditions. Do not use

24 
adjuvants containing penetrants such as petroleum-based oils after grass emergence on 
newly seeded grasses. 
Newly-seeded Areas 
Sterling may be applied either as a pre-plant or postemergence treatment 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 greater than 1 pint per acre 
may severely injure newly seeded grasses. Pre-plant application may injure new 
seedlings if the interval between application and grass planting is less than 45 days per 
pint of Sterling applied per acre west of the Mississippi River, or 20 days per pint per 
acre east of the Mississippi River. 
Established Grass Stands 
Established grass stands are perennial grasses planted one or more seasons prior to 
treatment. Application at rate greater than 1 pint per acre may injure the following grass 
varieties: bentgrass, carpetgrass, smooth brome, buffalograss, St. Augustine grass. 
Weeds Controlled 
Sterling applied at the indicated rates below will control many annual and biennial weeds 
and provide control or suppression of perennial weeds (see GENERAL WEED LIST). 
Rates and Timing 
Application rates and timing of Sterling treatments for CRP and set-aside acres are 
given below. Use the higher rates range when vegetation is dense or tall, or when 
weeds are growing under stress conditions such as drought or cold. 
Weed Stage and Type Rate per acre 
Annuals 
Small actively growing 1/4 to 1 pint (1/8 to 1/2 Ib ai) 
Established 1 pint (1/2Ib ai)

Rosette diameter 3 inches or more 1 to 2 pints (1/2 to 1 Ib ai) 
Bolting 2 pints (11b ai) 
Perennials 
Suppression/ control 2 pints (1 Ib ai) 
For best results, treat biennial weeds at the rosette stage. Biennial and perennial weeds 
will generally require sequential (follow-up) treatment for seedling control and escapes. 
Maximum single application rate 2 pts per acre (1 Ib ai/A) and no more than 2 
aQ~lications per year. 
Tank-mix treatments for CRPI Set-aside Acres 
To control grasses and additional broadleaf weeds, Sterling may be tank-mixed with 
other herbicides registered for use in CRP (Conservation Reserve Program) or Federal 
set-aside programs, including 2,4-0, glyphosate, paraquat, metsulfuron, and others. 
Read and follow all directions and precautions on the labels of tank mix partners.

ASPARAGUS 
(FOR USE ONLY IN CALIFORNIA, OREGON, AND WASHINGTON)

TURF AND LAWNS 
Sterling may be applied in general farmstead (non-crop) and in sod farms. Observe 
precautions, mixing, and application instructions on this label, plus the following: 
- To avoid injury to newly seeded grasses, delay application until after the second 
mowing. Rates greater than 1 pint (1/2 Ib ai) per acre may cause noticeable stunting or 
discoloration of some sensitive grass varieties such as bentgrass, carpetgrass, 
buffalograss, and St. Augustine grass. 
- In areas where roots of sensitive plants extend, do not apply at a rate greater than 1/4 
pint (1/8 Ib ai) per acre on coarse-textured (sandy) soils, or in excess of 1/2 pint (1/4 Ib 
ai) on fine-textured (clay) soils. Do not re-apply until at least 30 days after the prior 
application, and not until a prior application has been activated in the soil by rain or 
irrigation. 
Weeds Controlled 
When applied at the rates indicated below, Sterling will control many annual, biennial, 
and noted (*) perennial broadleaf weeds in turf. Sterling will also suppress many other 
listed broadleaf perennial and woody brush and vine species (see GENERAL WEED 
LIST).

Rates and Timing 
Apply 112 to 1 pint Sterling per acre on seedling grass after the crop reaches the 3 to 5 
leaf stage. Apply up to 2 pints Sterling per acre on established perennial grass crops. 
DO NOT APPLY AFTER THE GRASS SEED CROP BEGINS TO JOINT. For best 
performance, apply when weeds are at the 2 to 4 leaf stage, and rosettes are less than 2 
inches in diameter. Use the higher rates listed when weeds are more mature, or for 
dense vegetative growth. 
Maximum single application rate: 2 pints per acre (1 Ib ai/A) and no more than 2 
applications per year. 
Tank-mix Treatments 
For control of grasses or additional broadleaf weeds, Sterling may be tank-mixed with 
other herbicides registered for use in grass seed production. Read and follow all use 
directions, restrictions, and precautions on the labels of tank mix partners. 
Apply 112 to 2 pints Sterling with L~me of the following tank mix products: 
2,4-0 
Bromoxynil 
Clopyralid 
Diuron 
MCPA 
Annual Grass Control 
For suppression of annual grass weeds in grass seed crops, such as downy brome 
(cheatgrass), ripgut brome, rattail fescue, and windgrass, apply 2 pints per acre Sterling, 
in fall or late summer after harvest and burning of established seed crops. Apply 
immediately after the first irrigation when the soil is moist and before weeds have more 
than 2 leaves. Make no more than 2 applications per year. 
PREPLANT APPLICATION BEFORE WHEAT, CORN, SORGHUM, SOYBEANS 
(Post-harvest! Fallowl Crop Stubblel Set-aside) 
Sterling can be applied alone for control of some broadleaf weeds, or in tank mixture 
with the herbicides listed below. Sterling may be applied post-harvest in the fall, in 
spring or summer during fallow period, or to crop stubble or set-aside acres. For weeds 
controlled or suppressed, see the "Weeds Controlled" section under "SMALL 
GRAINS (WHEAT, BARLEY, OATS) (Not Underseeded To Legumes)". In addition, 
Sterling will control or suppress the following weeds: 
alfalfa 1 dogbane, hemp

1Regardless of weeds table in SMALL GRAINS section, these perennials will be 
controlled at rates lower than those listed for other perennial weeds. 
2See the "SPECIAL TANK MIX TREATMENTS" section below for control of these weeds.

28 
Rates and Timing 
Apply Sterling as a spot or broadcast treatment to emerged and actively-growing weeds 
after crop harvest and before a killing frost, or in fallow cropland or crop stubble the 
following spring or summer. Agriculturally-approved spray additives such as surfactants 
or oils may be used to enhance spray coverage penetration of weed foliage. See 
"Cropping Restrictions" below for recommended interval between application and 
planting to prevent crop injury. 
For best performance, apply when annual weeds are less than 6 inches tall, when 
biennial weeds are in the rosette stage, and to perennial weed regrowth in the summer 
or fall after mowing or tillage. The most effective control of upright perennial weeds such 
as Canada thistle and Jerusalem artichoke occurs if application is made when the 
majority of weeds such as field and hedge bindweed are in or beyond the bloom stage. 
Avoid disturbing treated areas following application. Treatments may not kill weeds that 
develop from seed or underground parts such as rhizomes or bulblets after the effective 
period for Sterling. For seedling control, a follow-up treatment or other cultural practice 
may be required. 
A r f t St r pp Ica Ion ra es, er Ing a one: 
Weed Type Rate per Acre 
annual 1/2 to 1 pint 
biennial 1/2 to 2 pints 
perennial 1 to 2 pints 
perennial suppression 1 to 2 pints 
perennials noted* (see GENERAL WEED LIST) 2 pints 
Other perennials 2 pints 
*Retreatments may be made as necessary, but do not exceed a total of 4 pints of 
Sterling per acre per year. 
Tank Mix Treatments 
(SEE ALSO "SPECIAL TANK MIX TREATMENTS" FURTHER BELOW) 
Sterling may be tank mixed with one or more of the following herbicides for control of 
grasses or additional broadleaf weeds. Read and follow all use directions, restrictions, 
and precautions on the labels of tank mix partners. 
Annual weed control: Apply 1/4 to 1 pint per acre Sterling with one of the following 
tank mix products: 
2,4-D 
Atrazine 
Chlorsulfuron + 
metsulfuron-methyl 
Glyphosate 
Metribuzin 
Metsulfuron-methyl 
Paraquat 
Pronamide 
Triasulfuron

Biennial and Perennial Weed Control: 
Apply 1 to 2 pints per acre Sterling with one or more of the following tank mix partners: 
2,4-0 
Chlorpyralid 
Glyphosate 
Picloram 
Special Tank-mix Treatments 
For suppression of perennial weeds, apply 1/2 to 1 pint Sterling per acre with 
glyphosate. 
29 
For wild garlic control, apply 1 pint Sterling per acre with 2,4-0 ester. Apply when garlic 
is 4 to 8 inches tall. 
For control of Canada thistle, use Sterling alone or with chlorpyralid + 2,4-0 or 
glyphosate. 
For control of volunteer barley, bulbous bluegrass, downy brome, jointed goatgrass, 
common rye and volunteer wheat, apply 1 pint Sterling per acre plus pronamide during 
fallow periods when weeds are actively growing. For best results, apply between mid­
October and mid-December before soil freeze-up. Fall-seeded wheat may be planted 9 
months or more following application. 
For improved control of kochia, wild buckwheat, prickly lettuce, field bindweed, and 
Canada thistle during fallow periods, apply 1/8 to 1/4 pint Sterling per acre plus 
glyphosate + 2,4-0 for annual weed control. A rate of 1/4 to 1/2 pint Sterling per acre 
plus glyphosate + 2,4-0 will provide suppression of perennial weeds. 
Cropping Restrictions 
The following restrictions are based on an annual application rate of Sterling of up to 4 
pints per acre: 
- CORN, SORGHUM, AND SOYBEANS may be planted in the spring following 
applications made during the previous year. If less than one inch of rainfall occurs 
between application and the first killing frost, cultivate treated areas to allow the 
herbicide to come into contact with moist soil. Cultivation may take place before or 
immediately after ground thaw. Soybean injury may occur if the interval between 
application and planting is less than specified. In areas with more than 30 inches per 
year of rainfall, delay planting for 30 days per pint of Sterling per acre. In areas with less 
than 30 inches of rainfall, delay planting for 45 days per pint of Sterling per acre. Do not 
count days when soil is frozen. 
- WHEAT may be planted in the fall or spring following applications. Spot applications 
may be made at any time prior to crop emergence if crop injury can be tolerated in 
treated areas. Wheat injury may occur if the interval between application and planting is 
less than specified. 
East of the Mississippi River, the interval is 20 days per pint of Sterling per acre. 
Moisture is essential for degradation of dicamba. Do not count days when ground is 
frozen.

Following harvest of wheat, barley or oats, any rotational crop may be planted, If the 
interval before harvest is shortened, such as when cover crops will be plowed under, do 
not follow with the planting of a sensitive crop, 
SPOT-APPLICATION CONTROL OF PERENNIAL WEEDS IN CROPLAND 
FOR USE ONLY IN THE STATES OF IDAHO, MONTANA, NEVADA, OREGON, UTAH, 
AND WASHINGTON 
Observe precautions, mixing, and application instructions on this label, plus the 
following: 
- Do not treat subirrigated cropland or areas where the soil remains saturated with water 
throughout the year. 
- Make only one application of Sterling per year. 
Weeds Controlled 
Sterling applied as directed will control many weeds including the following: 
bindweed, field 
dock, broadleaf (bitterdock) 
dock, curly 
knapweed, black 
knapweed, Russian 
ragwort, tansy 
spurge, leafy 
thistle, Canada 
Rates and Timing 
Sterling may be applied at any time following crop harvest to stubble, fallow, or other 
cropland. Apply when weeds are actively growing and before a killing frost. Apply 1 
quart (1 Ib ai) Sterling per acre. Application may be made at least 1 month prior to 
planting of wheat. 
DO NOT USE UNLESS INJURY TO WHEAT OR ROTATED BARLEY WILL BE 
ACCEPTABLE. 
Barley, oats, corn, sorghum (milo), annual or perennial grass crops may be planted into 
treated areas 1 year after application. Crops grown for seed (other than perennial grass 
seed) must not be planted back into treated areas until 3 years after application. Do not 
plant broad leaf crops such as alfalfa, beans, peas, potatoes, or sugar beets into treated 
areas until after 2 years after application. 
In most cases, treatment will not kill perennial weed seedlings which germinate from 
seed one or 2 years after treatment. Once the effect of Sterling has been lost, a follow­
up program for seedling control will be required. 
WIPER APPLICATION USES 
Sterling may be applied by wiper equipment to control or suppress actively growing 
broadleaf weeds, brush and vines. Use a mixture of 1 part Sterling to 1 part water. 
Observe precautions, mixing, and application instructions on this label, plus the 
following: 
- Do not contact desirable vegetation with herbicide mixture. 
- Wiper application may be made to crops, including pasture listed on this label with the 
exception of grain sorghum (milo), as well as non-cropland areas.
