ENVIRONMENTAL HAZARDS
This product is toxic to fish. Do not apply directly to water, to areas where surface water is present or to intertidal areas
below the mean high water mark. Drift or runoff may be hazardous to non-target plants and aquatic organisms in 
neighboring areas. Do not apply where runoff is likely to occur. Do not apply when weather conditions favor drift from 
treated areas. Do not contaminate water when cleaning equipment or disposing of equipment washwaters or rinsate. 
Groundwater Advisory 
This product has properties and characteristics associated with chemicals detected in groundwater. This product may 
leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow. 
Surface Water Advisory 
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining 
soils and soils with shallow ground water. This product is classified as having high potential for reaching surface water 
via runoff for several days or more after application. A level, well-maintained vegetative buffer strip between areas to 
which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential 
loading of this product from runoff water and sediment. Runoff of this product will be greatly reduced by avoiding 
applications when rainfall or irrigation is expected to occur within 48 hours .
Windblown Soil Particles Advisory 
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion usually have 
a high silt and/or fine to very fine sand fractions and low organic matter content. Other factors which can affect the 
movement of windblown soil include the intensity and direction of prevailing winds, vegetative cover, site slope, 
rainfall, and drainage patterns. Avoid applying this produc if prevailing local conditions may be expected to result in 
off-site movement. 
Non-target Organism Advisory 
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including 
pollinators, in areas adjacent to the treated area. Protect the forage and habitat of non-target organisms by minimizing 
spray drift. For further guidance and instructions on how to minimize spray drift, refer to the Spray Drift Management 
section of this label.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only 
protected handlers may be in the area during application. 
For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation. 
SENTRALLAS® herbicide, referred to below as SENTRALLAS herbicide, must be used accordance with the 
directions for use on this label. 
SENTRALLAS herbicide may be used on wheat (including durum), triticale, barley, and oats in most states. Check 
with your state extension service or Department of Agriculture before use, to be certain SENTRALLAS herbicide is 
registered in your state.

PRODUCT INFORMATION
SENTRALLAS herbicide is used for selective postemergence control or suppression of broadleaf weeds in wheat 
(winter, spring and durum), triticale, barley and oats not underseeded with legumes or grasses. SENTRALLAS
herbicide contains two active ingredients formulated as oil dispersion. SENTRALLAS herbicide is to be mixed with 
water and applied as a uniform broadcast spray early postemergence to the crop, and to the main flush of actively 
growing broadleaf weeds. 
BIOLOGICAL ACTIVITY AND ENVIRONMENTAL CONDITIONS
Warm, moist growing conditions promote active weed growth and enhance the activity of SENTRALLAS herbicide
by allowing maximum foliar uptake and contact activity. Weeds hardened off by cold weather or drought stress may 
not be adequately controlled or suppressed and regrowth may occur. SENTRALLAS herbicide may injure crops that 
are stressed from adverse environmental conditions (including extreme temperatures or moisture), abnormal soil 
conditions, or cultural practices. For best results, ensure thorough spray coverage of target weeds. See remaining 
"DIRECTIONS FOR USE" sections of this label for complete use details. 
Degree of control and duration of effect are dependent on weed sensitivity, weed size, crop competition, growing 
conditions at and following treatment, and spray coverage. 
SENTRALLAS herbicide is rain-fast 1 hour after application.
RESTRICTIONS
Injury to or loss of desirable trees, adjacent sensitive crops, or vegetation may result from failure to observe the 
following: 
x DO NOT apply, drain or flush equipment on or near desirable trees or other plants or on areas where their roots 
may extend, or in locations where the chemical may be washed or moved into contact with their roots. 
x DO NOT discharge excess material on the soil at a single spot in the field, grove, or mixing/loading station. 
x DO NOT store pesticides near well sites. 
x DO NOT apply SENTRALLAS herbicide to wheat, triticale, barley, or oats that is stressed by severe weather 
conditions, drought, low fertility, water-saturated soil, disease, or insect damage, as crop injury may result. Risk 
of injury is greatest when crop is in the 2 to 5- leaf stage. Severe winter stress, drought, disease, or insect 
damage following application also may result in crop injury. 
x DO NOT apply to irrigated land where tailwater will be used to irrigate crops other than wheat, triticale, barley, 
and oats. 
x DO NOT apply by air in the State of New York. 
x DO NOT apply SENTRALLAS herbicide within 60 days of crop emergence where an organophosphate 
insecticide has been applied as an in-furrow treatment because crop injury may result. 
x DO NOT use SENTRALLAS herbicide plus malathion-containing products because crop injury may result. 
x DO NOT apply to crops underseeded to legumes or grasses as injury to forage may result. 
x DO NOT apply through any type of irrigation system.

PRECAUTIONS
• Varieties of wheat (including durum), barley, triticale, and oats may differ in their response to various herbicides. 
Consult your state experiment station, university, or extension agent as to crop sensitivity to any herbicide. If no 
information is available, limit the initial use to a small area. 
• Applications of SENTRALLAS herbicide to crops that are stressed by severe weather conditions, drought 
(including low levels of subsoil moisture), near freezing temperatures prior to, at, and following time of application, 
low fertility, water-saturated soil, disease, or insect damage, may result in crop injury and reduced weed control. 
• Under certain conditions including heavy rainfall, prolonged cold weather, or wide fluctuations in day/night 
temperatures prior to or soon after SENTRALLAS herbicide application, temporary discoloration and/or crop injury 
may occur. To reduce the potential of crop injury, tank mix SENTRALLAS herbicide with 2,4-D (ester formulations 
perform best - see the "TANK MIXTURES" section of this label) and apply after the crop is in the tillering stage of 
growth. 
• Effects of Temperature on Herbicidal Activity: Herbicidal activity of SENTRALLAS herbicide is influenced by 
weather conditions. Optimum activity requires active plant growth. The temperature range for optimum herbicidal 
activity is 55°F to 75°F. Reduced activity will occur when temperatures are below 45°F or above 85°F. Frost before 
application (3 days) or shortly after (3 days) may reduce weed control and crop sensitivity.
• Calibrate sprayers only with clean water away from the well site. Make scheduled checks of spray equipment. 
Ensure that all operation employees accurately measure pesticides. Mix only enough product for the job at hand and 
avoid overfilling of spray tank. 
• When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix.

WEED RESISTANCE MANAGEMENT
SENTRALLAS herbicide, which contains the active ingredients thifensulfuron-methyl and fluroxpyr is a group 2 
and 4 herbicide based on the mode of action classification system of the Weed Science Society of America. 
Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to 
one or more herbicides is a best practice. A diversified weed management program may include the use of multiple 
herbicides with different sites of action and overlapping weed spectrum with or without tillage operations and/or 
other cultural practices. Research has demonstrated that using the labeled rate and directions for use is important to 
delay the selection for resistance. 
The continued effectiveness of this product depends on the successful implementation of a weed resistance 
management program. To aid in the prevention of developing weeds resistant to this product, users should: 
• Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed 
sizes present. 
• Start with a clean field, using either a burndown herbicide application or tillage. 
• Control weeds early when they are relatively small (less than 4 inches). 
• Apply full rates of SENTRALLAS herbicide, for the most difficult to control weed in the field at the specified time 
(correct weed size) to minimize weed escapes. 
• Scout fields after application to detect weed escapes or shifts in control of weed species. 
• Control weed escapes before they reproduce by seed or proliferate vegetatively. 
• Report any incidence of non-performance of this product against a particular weed to your FMC representative, 
local retailer, or county extension agent. 
• Contact your FMC representative, crop advisor, or extension agent to find out if suspected resistant weeds to these 
MOAs have been found in your region. Do not assume that each listed weed is being controlled by multiple sites of 
action. Products with multiple active ingredients are intended to broaden the spectrum of weeds that are controlled. 
Some weeds may be controlled by only one of the active ingredient in this product.
• If resistance is suspected, treat weed escapes with an herbicide having a site of action other than Group 2 and/or 
use nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production. 
• Suspected herbicide-resistant weeds may be identified by these indicators: 
- Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is 
achieved on adjacent weeds; 
- A spreading patch of non-controlled plants of a particular weed species; and 
- Surviving plants mixed with controlled individuals of the same species.
Additionally, users should follow as many of the following herbicide resistance management practices as is 
practical: 
• Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program. 
• Utilize sequential applications of herbicides with alternative sites of action. 
• Rotate the use of this product with non-Group 2 herbicides. 
• Avoid making more than two applications of SENTRALLAS herbicide, and any other Group 2 herbicides within a 
single growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum 
for the difficult-to control weeds. 
• Incorporate non-chemical weed control practices, including mechanical cultivation, crop rotation, cover crops and 
weed-free crop seeds, as part of an integrated weed control program. 
• Use good agronomic principles that enhance crop development and crop competitiveness. 
• Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. 
• Manage weeds in and around fields, during and after harvest to reduce weed seed production. 
INTEGRATED PEST MANAGEMENT
This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, 
cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field 
scouting or other detection methods, correct target pest identification, population monitoring, and treating when 
target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, 
professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for 
treating specific pest/crop systems in your area.

SPECIFIC WEED INSTRUCTIONS
1Common chickweed (ALS resistant): Apply a minimum of 11 fl oz/A* of SENTRALLAS herbicide when the 
majority of the chickweed has germinated and are past the cotyledon stage but are small (1 to 6 leaf, less than 4
inches tall) and actively growing but before crop canopy prevents thorough coverage of weeds. Chickweed
emerging after application will not becontrolled.
2Wild buckwheat: Apply a minimum of 11 fl oz/A* of SENTRALLAS herbicide when the majority of the 
wild buckwheat has germinated and are past the cotyledon stage but are small (less than 3 inches tall or
across) and actively growing but before crop canopy prevents thorough coverage ofweeds.
3Wildgarlic:ApplySENTRALLAS herbicidewhenwildgarlicplantsarelessthan12inchestallwith2to4
inchesof new growth. Control may be reduced when plants are hardened-off by cold weather and/or drought 
stress. Control is enhanced when applications are made during warm temperatures to actively growing wild 
garlic plants. Typical symptomsofdyingwildgarlicplants(discolorationandcollapse)maynotbenoticeable
for2-5weeks.
4Wild radish: Apply 11 to 14 fl oz/A* of SENTRALLASherbicide plus surfactant in the fall or spring to
wild radish rosettes less than 6 inches in diameter. Applications made later than 30 days after weed
emergence will result in partial control. Fall applications PXVW be made prior to hardening-off of plants.
5Russian thistle: For best results use SENTRALLAS herbicide in a tank mix with dicamba (including
Banvel® herbicide/ Clarity® herbicide) and 2,4-D or MCPA (ester or amine) or bromoxynil containing
products (includingBison® herbicide, Bronate® herbicide,Bronate Advanced™ herbicideor Buctril® 
herbicide).
6SU/IMIDAZOLINONETolerant Volunteer sunflower : Control with SENTRALLAS herbicide applied 
below 11 fl oz/A may not be adequate because varieties resistant to SU and IMI products could be present. For 
best results increase the rate of SENTRALLAS herbicide to at least 11 fl oz/A.*

TANK MIXTURES
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and 
follow the applicable restrictions and limitations and directions for use on all product labels involved in tank 
mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in 
the tank mixture.
Physical Compatibility
SENTRALLASherbicide is physically compatible with many common used herbicides, fungicides, 
insecticides, liquid fertilizers, non-ionic surfactants, crop oils, methylated seed oils and drift control additives. 
However, since the formulations of products change, it is important to test the physical compatibility of
desired tank mixes and check for undesirable physical effects, including settling out or flocculation. To
determine physical compatibility, add the proportions of the tank mix products and water to a clear glass quart
container with lid, mix thoroughly and allow to stand for 30 minutes. If the combination remains mixed, or
can be re-mixed readily, it may be considered physically compatible.
SENTRALLAS herbicide may be tank mixed with other suitable registered herbicides to control weeds listed as 
partially controlled, weeds resistant to SENTRALLAS herbicide or weeds not listed under the "WEEDS 
CONTROLLED/SUPPRESSED" section of this label.
Crop varieties can differ in their responsiveness to tank mixtures, andenvironmental conditions can have an
influence on product performance and crop response. Some materials including oils, surfactants, adjuvants and 
pesticide formulations when applied individually, sequentially, or in tank mixtures may solubilize the plant 
cuticle, facilitate penetration into plant tissues, and increase the potential for crop injury. It is not possible to
test SENTRALLAS herbicide alone or with all possible tank mix combinations and sequences on all varieties 
under all environmental conditions. When considering the use of a tank mixture on a labeled crop without
prior experience, or which is not specifically described on SENTRALLAS herbicide product labeling or in
other FMC product use instruction, it is important to check crop safety first. To test for crop safety,prepare a
small volume of the intended tank mixture or sequence, apply it to an area of the target crop as directed by
both this and the tank mix partner products labels, and observe the treated crop to ensure that a phytotoxic 
response does not occur.

12
 
Use of SENTRALLAS herbicide in any tank mixture or sequence of applications that is not specifically described 
on SENTRALLAS herbicide product labeling or in other FMC product use instructions, could potentially result in 
crop injury. Follow the restrictions and precautions on this label and on the label for any other product to be used 
in tank mixtures or in sequential applications before making such applications to your crops. Follow the most 
restrictive label. To the extent consistent with applicable law, FMC will not be responsible for any crop injury 
arising from the use of a tank mixture or sequence of applications that is not specifically described on 
SENTRALLAS herbicide product labeling or in other FMC product use instruction.
With 2,4-D (amine or ester) or MCPA (amine or ester)
SENTRALLAS herbicide may be tank mixed with the amine and ester formulations 2,4-D and MCPA 
herbicides. For best results in the Red River Valley and adjacent areas of North Dakota and Minnesota, add the
ester formulations of these herbicides to the tank at 0.375 lb active ingredient/A. No additional surfactant is 
needed with this mixture. For best results in other areas, add the ester formulations of 2,4-D or MCPA herbicides 
to the tank at 0.25 to 0.375 lb active ingredient. Nonionic surfactant may be added to the mixture at 0.5 to 1 quart 
per 100 gallons of spray solution; however, adding nonionic surfactant may increase the potential for crop injury, 
especially at the higher phenoxy rates.
With dicamba (including Banvel® herbicide/Clarity® herbicide)
SENTRALLAS herbicide may be tank mixed with dicamba. Nonionic surfactant may be added to the mixture 
at 0.5 to 1 quart per 100 gallons of spray solution; however, adding nonionic surfactant may increase the 
potential for crop injury.
With 2,4-D (amine or ester) or MCPA (amine or ester) and dicamba
SENTRALLAS herbicide may be applied in a 3-way tank mix with formulations of 2,4-D or MCPA and 
dicamba. Nonionic surfactant may be added to the mixture at 0.5 to 1 quart per 100 gallons of spray 
solution; however, adding nonionic surfactant may increase the potential for crop injury, especially at the 
higher phenoxy rates. Apply to winter wheat, winter triticale, and winter oats after the crop is tillering and 
prior to jointing (first node). In Spring Wheat (including Durum), Spring triticale, and Spring Oats, apply 
after the crop is tillering and before it exceeds the 5-leaf stage. In Spring Barley, apply after the crop is 
tillering and before it exceeds the 4-leaf stage.
With Other Broadleaf Control Products
SENTRALLAS herbicide may be tank mixed with other broadleaf herbicides registered on cereals including
Express® herbicide, Ally® XP herbicide, WideMatch® herbicide, Aim® EC herbicide, Stinger® herbicide, or 
Curtail® herbicide branded products, as well as herbicides containing bromoxynil, metribuzin and glyphosate.
Tank mixtures of SENTRALLAS herbicide plus metribuzin may result in reduced control of wild garlic.
With Grass Control Products
For improved control of grass weeds, SENTRALLAS herbicide may be tank mixed with other grass control 
herbicides registered on cereals including GR1™ herbicide, GR2™ herbicide, Axial® XL herbicide, Discover®
NG herbicide, "Everest®” branded products, Hoelon® 3EC herbicide, Maverick® herbicide, Puma® 1EC 
herbicide or Varro® herbicide. Antagonism generally does not occur; however, FMC advises that you first 
consult your state experiment station, university, or extension agent, Agricultural dealer, or FMC representative 
as to the potential for antagonism before using the mixture. If no information is available, limit the initial use of 
SENTRALLAS herbicide and the grass product to a small area.
With Fungicides
SENTRALLAS herbicide may be tank mixed or used sequentially with fungicides registered for use on cereal 
crops.
With Insecticides
SENTRALLAS herbicide may be tank mixed or used sequentially with insecticides registered for use on 
cereal crops; however, under certain conditions (drought stress, cold weather, or if the crop is in the 2 to 4 leaf 
stage), tank mixtures or sequential applications of SENTRALLAS herbicide with organophosphate 
insecticides may produce temporary crop yellowing or, in severe cases, crop injury. The potential for crop 
injury is greatest when wide fluctuations in day/night temperatures occur just prior to or soon after 
application. Test these mixtures in a small area before treating large areas.

13
 
DO NOT apply SENTRALLAS herbicide within 60 days of crop emergence where an organophosphate 
insecticide has been applied as an in-furrow treatment because crop injury may result.
DO NOT use SENTRALLAS herbicide plus malathion containing products because crop injury may result.
With Liquid Nitrogen Solution Fertilizer
Liquid nitrogen fertilizer solutions may be used as a carrier in place of water. Run a tank mix compatibility test 
before mixing SENTRALLAS herbicide in fertilizer solution. SENTRALLAS herbicide must first be mixed with 
water and then added to liquid nitrogen solutions (e.g., 28-0-0, 32-0-0). Ensure that the agitator is running while 
the SENTRALLAS herbicide is added. Use of this mixture may result in temporary crop yellowing and stunting.
If using low rates of liquid nitrogen fertilizer in the spray solution (less than 50% of the spray solution volume), 
the addition of surfactant is necessary. Add surfactant at 0.5 to 2 pt per 100 gal of spray solution (0.06 to 0.25% 
v/v) based on local guidance.
When using high rates of liquid nitrogen fertilizer solution in the spray solution, adding surfactant increases the 
risk of crop injury. If 2,4-D or MCPA is included with SENTRALLAS herbicide and fertilizer mixture, ester 
formulations tend to be more compatible (see manufacturer’s label). Additional surfactant may not be needed 
when using SENTRALLAS herbicide in tank mix with 2,4-D ester or MCPA ester and liquid nitrogen fertilizer 
solutions. Consult your agricultural dealer, consultant, field advisor, or FMC representative for guidance before 
adding an adjuvant to these tank mixtures.
Note: In certain areas east of the Mississippi river unacceptable crop response may occur with use of straight or 
dilute nitrogen fertilizer carrier solutions where cold temperatures or widely fluctuating day/night temperatures 
exist. In these areas consult your agricultural dealer, consultant, field advisor, or FMC representative for 
guidance before using nitrogen fertilizer carrier solutions.
DO NOT use low rates of liquid nitrogen fertilizer solution as a substitute for a surfactant. Liquid nitrogen 
fertilizer solutions that contain sulfur may increase crop response.
DO NOT use with liquid fertilizer solutions with a pH less than 3.0.
SPRAY ADJUVANTS - ALL CROPS OR USES
Include a spray adjuvant with applications of SENTRALLAS herbicide. In addition, an ammonium nitrogen 
fertilizer may be used. See TANK MIXTURES for additional information on adjuvant specifications for certain 
tank mixtures. Consult your Ag dealer or applicator, local FMC fact sheets and technical bulletins prior to using 
an adjuvant system. If another herbicide is tank mixed with SENTRALLAS herbicide select adjuvants authorized 
for use with both products. Products must contain only EPA- exempt ingredients.
NONIONIC SURFACTANT (NIS)
• Apply 0.06 to 0.25% v/v (0.5 to 2 pt per 100 gal of spraysolution).
• Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (HLB) 
greater than 12.
CROP OIL CONCENTRATE (COC) - PETROLEUM OR MODIFIED SEED OIL (MSO)
• Apply at 1% v/v (1 gal per 100 gal spray solution). MSO adjuvants may be used at 0.5% v/v if specified 
on local FMC product literature or servicepolicies.
• Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed oil 
with at least 15% surfactantemulsifiers.
AMMONIUM NITROGEN FERTILIZER
• Use 2 qt/A of a high-quality urea ammonium nitrate (UAN), including 28%N or 32%N, or 2 lb/A of a 
spray-grade ammonium sulfate (AMS). Use 4 qt/A UAN or 4 lb/A AMS under arid conditions.
• See TANK MIXTURES With Liquid Nitrogen Fertilizer for instructions on using fertilizer as a carrier in place of
water.
SPECIAL ADJUVANT TYPES
• Combination adjuvant products may be used at doses that provide the required amount of NIS, COC, MSO and/or
ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions.

14
 
• In addition to the adjuvants specified above, other adjuvant types may be used if they provide the same 
functionality and have been evaluated and approved by FMC product management. Consult separate FMC 
technical bulletins for detailed information before using adjuvant types not specified on this label.
MIXING INSTRUCTIONS
Select a spray volume that will ensure thorough coverage and a uniform spray pattern. If tank mixing with other 
herbicides, always consult the label of the tank mix partner(s) for minimum spray volume requirements and apply 
the tank mixture using a water volume directed for all products.
1. Always start with a clean and empty sprayer tank.
2. Fill the tank with clean water one half of the required sprayvolume.
3. With the agitator running, add the required amount of SENTRALLAS herbicide. Continue to agitate for a
minimum of 5 minutes to ensure that SENTRALLAS herbicide is completely dispersed.
4. If tank mixing SENTRALLAS herbicide with another herbicide, follow this mixing order: dry flowables and 
soluble granules, followed by liquids, then oil dispersions (OD) or emulsifiable concentrates (EC). Maintain 
continuous agitation.
5. Add the rest of the water.
6. If required for the tank mixture, add the appropriate adjuvant. If an antifoam agent is required, add last.
7. Continue agitation sufficient enough to maintain a uniform spray solution.
8. Refer to the tank mix sections of this booklet for mixing order and other mixing instructions.
SPRAY EQUIPMENT
For specific application equipment, refer to the manufacturer’s instructions for additional information 
on GPA, pressure, speed, nozzle types and arrangements.
Be sure to calibrate air or ground equipment properly before application. Select a spray volume and delivery 
system that will ensure thorough coverage and a uniform spray pattern with minimum drift. Use higher spray 
volumes to obtain better coverage when crop canopy is dense. Avoid swath overlapping, and shut off spray booms 
while starting, turning, slowing, or stopping, to avoid injury to the crop.
GROUND APPLICATION
For optimum spray distribution and thorough coverage, use flat-fan or low-volume flood nozzles.
• Overlaps or starting, stopping, slowing, and turning while spraying may result in crop injury.
• For flat-fan nozzles, use a spray volume of at least 8 gal/A (GPA).
• For flood nozzles on 30" spacing, use flood nozzles no larger than TK10 (or the equivalent), a pressure of at 
least 30 psi and a spray volume of at least 10 GPA only. For 40" nozzle spacing, use at least 13 GPA; for 60" 
spacing use at least 20 GPA. It is essential to overlap the nozzles 100% for all spacings.
• "Raindrop RA" nozzles are not advised for SENTRALLAS herbicide applications, as weed control 
performance may be reduced.
• Use screens that are 50-mesh or larger.
AERIAL APPLICATION
For aerial application, select nozzles and pressure that provide optimum spray distribution and maximum 
coverage at 3 to 5 GPA.
Use at least 3 GPA. DO NOT apply SENTRALLAS herbicide by air in the state of New York.

x For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE
S572.1).
x Do not apply when wind speeds exceed 10 miles per hour at the application site.
x Do not apply during temperature inversions.
 
Aerial Applications: 
x Do not release spray at a height greater than 10 feet above the vegetative canopy, unless a greater 
application height is necessary for pilot safety.
x For applications prior to the emergence of crops and target weeds, applicators are required to use a 
Coarse or coarser droplet size (ASABE S572.1).
x For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE
S572.1).

diameter for helicopters.
x Applicators must use one-half swath displacement upwind at the downwind edge of the field.
x Nozzles must be oriented so the spray is directed toward the back of the aircraft.
x Do not apply when wind speeds exceed 10 miles per hour at the application site.
x Do not apply during temperature inversions. 
SPRAY DRIFT MANAGEMENT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT.
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide 
target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be 
greater if applications are made improperly or under unfavorable environmental conditions.
Controlling Droplet Size – Ground Boom
• Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the 
highest practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle 
with a higher flow rate.
• Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and
droplet size.
• Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles 
designed to reduce drift.
Controlling Droplet Size – Aircraft
• Adjust Nozzles - Follow nozzle manufacturers recommendations for setting up nozzles. Generally, to reduce 
fine droplets, nozzles should be oriented parallel with the airflow inflight.
BOOM HEIGHT – Ground Boom
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. 
For ground equipment, the boom should remain level with the crop and have minimal bounce.

16
 
RELEASE HEIGHT - Aircraft
Higher release heights increase the potential for spray drift. When applying aerially to crops, do not 
release spray at a height greater than 10 ft above the crop canopy, unless a greater application height is 
necessary for pilot safety.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. 
Verify that the shields are not interfering with the uniform deposition of the spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. Temperature inversions are characterized by 
increasing temperature with altitude and are common on nights with limited cloud cover and light to no 
wind. The presence of an inversion can be indicated by ground fog or 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.
Avoid applications during temperature inversions.
WIND
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND 
CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect 
spray drift.
HANDHELD TECHNOLOGY APPLICATIONS:
• Take precautions to minimize spray drift. 
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read 
and carefully observe cautionary statements and all other information on the additive’s label. If using an additive that 
increases viscosity, ensure that the nozzles and other application equipment will function properly with a viscous spray 
solution. Preferred drift control additives have been certified by the Chemical Producers and Distributors Association 
(CPDA).
SPRAY TANK CLEANOUT
BEFORE SPRAYING SENTRALLAS HERBICIDE
The sprayequipment must be clean before SENTRALLAS herbicide is sprayed. Follow the cleanup procedures
specified on the labels of the previouslyapplied products. If no directions are provided, followthe four steps
outlined in the After Spraying SENTRALLAS herbicide section of this label.
AT THE END OF THE DAY
When multiple loads of SENTRALLAS herbicide are applied, it is advised that at the end of each day of spraying 
the interior of the tank be rinsed with fresh water and then partially filled, and the boom and hoses flushed. 
This will prevent the buildup of dried pesticide deposits which can accumulate in the application equipment.

17
 
AFTER SPRAYING SENTRALLAS HERBICIDE AND BEFORE SPRAYING CROPS OTHER THAN
WHEAT, BARLEY, TRITICALE, AND OATS
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately
following applications of SENTRALLAS herbicide as follows:
1. Empty the tank and drain the sump completely.
2. Spray the tank walls with clean water using a minimum volume of 10% of the tank volume. Circulate the water
through the lines, including all bypass lines, for at least two minutes. If boom is equipped with multiple nozzle 
bodies, be sure to rotate through all nozzles to ensure clean water reaches all parts of these assemblies. Flush the 
boom well and empty the sprayer. Completely drain thesump.
3. Visually inspect the tank to ensure removal of all visible herbicide residues. If necessary, repeat Step 2.
4. Fill the tank with clean water, and then add 1 gallon of a high pH sprayer tank cleaner, per 100 gallons of water, 
or an equivalent amount of household AMMONIA (containing minimum of 3% ammonia) per 100 gallons of water. 
A high pH tank cleaner or ammonia will not neutralize the herbicide, but helps dissolve any residual herbicide
deposits.
5. Flush the solution through boom and hoses, and then add more water to completely fill tank. Allow to sit for
at least 15 minutes with agitation.
6. Drain the tank and sump.
7. Remove the nozzles and screens and clean separately in a bucket containing cleaning agent and water.
8. Thoroughly rinse the tank with clean water for a minimum of 5 minutes, flushing water through the hoses and boom.
9. The rinsate solution may be applied back to the crop(s) specified on this label. If cleaners are used, consult the
cleaner label for rinsate disposal instructions. If no instructions are given, dispose of the rinsate on site or at an 
approved waste disposal facility.
Notes:
1. Steam-cleaning aerial spray tanks is advised to facilitate the removal of any caked deposits.
2. When SENTRALLAS herbicide is tank mixed with other pesticides, all cleanout procedures for each product
needs to be examined and the most rigorous procedure must be followed.
3. Follow any pre-cleanout guidelines specified on other product labels.
