Surface Water Advisory. This product may impact sur-
face water quality due to runoff of rainwater . This is 
especially true for poorly draining soils and soils with shal -
low groundwater . This product is classified as having high 
potential for reaching surface water via runoff for several 
months or more after application . A level, well-maintained 
buffer strip between areas to which this product is applied 
and surface water features including ponds, streams, and 
springs will reduce the potential loading of saflufenacil, 
pyroxasulfone, and pyroxasulfone’s degradation product, 
[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)-1H- 
pyrazol-4-yl]methanesulfonic acid (M1), from runoff water 
and sediment . Runoff of this product will be reduced by 
avoiding application when rainfall is forecast to occur with -
in 48 hours .
Point-source Contamination. To prevent point-source 
contamination, DO NOT mix or load this or any other pes-
ticide product within 50 feet of wells (including abandoned 
wells and drainage wells), sinkholes, perennial or intermit-
tent streams and rivers, and natural or impounded lakes 
and reservoirs . This setback does not apply to properly 
capped or plugged abandoned wells and does not apply 
to impervious pad or dike mixing/loading areas described 
as follows .
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 suffi -
cient capacity to contain all product spills, equipment or 
container leaks, equipment washwater, and rainwater that 
may fall on the pad . The containment capacity does not 
apply to vehicles delivering pesticide shipments to the mix -
ing and/or 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:
• Back-siphoning into wells
• Spills
• Improper disposal of excess pesticide, spray mixes, or 
rinsates
Check valves or anti-siphoning devices must be used on 
all mixing equipment .

Product Information
SurtainTM herbicide provides rate-dependent residual 
preemergence control of annual grass weeds, sedges, and 
annual broadleaf weeds (including biotypes resistant to 
ACCase inhibitors, ALS inhibitors, HPPD inhibitors, PSII 
inhibitors, and glyphosate) (refer to Table 1 for list) . It can 
be used in field corn (grain, seed, silage), fallow, and post-
harvest croplands .
Periods of dry weather following application of Surtain 
may reduce herbicidal effectiveness . Residual 
 preemergence application of Surtain must be activated 
by at least 1/2 inch of rainfall or sprinkler irrigation before 
weed seedling emergence . When Surtain is not activated, 
a labeled postemergence herbicide or cultivation may be 
needed to control weed escapes . Surtain does not con-
trol emerged weeds .
Herbicidal activity of Surtain may be reduced if excessive 
trash from the previous crop covers the soil surface during 
application . Manage trash levels if needed with combine 
straw shredder/spreaders, earlier burndown of emerged 
weeds, or light tillage .

1 Surtain must be used in tank mixes or sequential applications with other labeled herbicides that provide additional control of noted weeds .
Mode of Action
Surtain contains two active herbicide ingredients . 
Saflufenacil is a potent inhibitor of protoporphyrin- 
ogenoxidase belonging to herbicide mode-of-action 
Group 14 . Pyroxasulfone is a potent inhibitor of very long 
chain fatty acid (VLCFA) synthesis, belonging to herbicide 
mode-of-action Group 15 . Saflufenacil is rapidly absorbed 
by roots and foliage . Following inhibition of the 
 protoporphyrinogen-oxidase, plant death is the result of 
membrane damage . Under active growing conditions, sus-
ceptible emerging weed seedlings usually develop 
chlorotic and necrotic injury symptoms within hours and 
die within a few days . Susceptible germinating weed seeds 
usually die as they reach the soil surface or shortly after 
emergence . Pyroxasulfone is a root-and-shoot inhibitor 
that controls susceptible weed seedlings before or soon 
after they emerge from the soil .
Herbicide Resistance Management
For resistance management, Surtain contains both a 
Group 14 herbicide and Group 15 herbicide . Any weed 
population may contain plants naturally resistant to

8
Group 14 and/or Group 15 herbicides . The resistant indi-
viduals may dominate the weed population if these 
herbicides are used repeatedly in the same fields . Appropri-
ate resistant-management strategies should be followed .
To delay herbicide resistance consider:
• Avoiding the consecutive use of herbicides that have a 
similar target-site-of-action on the same weed species .
• Using tank mixes or premixes with herbicides from 
 different target-site-of-action groups as long as the 
involved products are all registered for the same use, 
have different sites of action, and are both effective at the 
tank mix or prepack rate on the weed(s) of concern .
• Basing herbicide use on a comprehensive IPM 
 (Integrated Pest Management) program including cultural 
and mechanical methods .
• Monitoring treated weed populations for loss of field effi -
cacy, and control of escapes with effective alternative 
herbicides or mechanical methods .
• Identify weeds present in the field through scouting and 
field history and understand their biology . The weed- 
control program needs to consider all of the weeds 
present .
• Scout fields prior to application to identify the weed spe -
cies present and their growth stage to determine if the 
intended application will be effective .
• Scout fields after application to verify the treatment was 
effective .
• Suspected herbicide-resistance weeds may be identified 
by these indicators: 
1 . Failure to control a weed species normally controlled 
by the herbicide at the dose applied, especially if con -
trol is achieved on adjacent weeds; 
2 . A spreading patch of non-controlled plants of a partic-
ular weed species; or 
3 . Surviving plants mixed with controlled individuals of 
the same species .
• If resistance is suspected, treat weed escapes with a 
herbicide with a different MOA and/or use non-chemical 
methods to remove escapes, as practicable, with the 
goal of preventing further seed production .
• Report any incidence of non-performance of this product 
against a particular weed species to your BASF 
representative .
• Contacting your local extension specialist, certified crop 
advisors, and/or manufacturer for herbicide resistance 
management and/or integrated weed management 
directions for specific crops and resistant weed biotypes .
Crop Response
Crops listed on this label are tolerant to SurtainTM 
 herbicide when applied according to label directions and 
under normal environmental conditions . Crop injury may 
occur when application is made under stressful growing 
conditions (e .g . mechanical injury, drought or excessive 
moisture for normal crop development, extreme hot or 
cold temperatures, widely fluctuating temperatures, seed -
ling disease, low soil fertility, high soil pH, high soil salt 
concentration, or other pesticide injury) .
Application Instructions
Surtain may be applied before or after crop emergence .
Application Rate
Application rates of Surtain may vary depending on soil 
texture and organic matter . Refer to Table 2 for soil texture 
groups used in this label .

Application Timing
Surtain may be applied preplant surface, preplant incor-
porated, preemergence, or early postemergence . Refer to 
the Crop-specific Information section for specific appli-
cation instructions (timings, rates, restrictions and 
precautions) by crop .
Preplant Surface Application. Apply Surtain alone or 
in tank mix within 30 days of planting . If weeds are present 
at the time of application, use additional weed control 
methods, for example a tank mix with an appropriate 
postemergence herbicide(s), to control emerged weeds .
Preplant Incorporated (PPI) Application. Incorporate 
 Surtain into the upper (1 to 2 inches) soil surface within 
14 days of planting . Deeper incorporation may increase the 
potential for crop injury and also may result in reduced 
weed control . Use appropriate equipment for uniform shal-
low incorporation, including a field cultivator, harrow, rolling 
cultivator, or finishing disc .
Preemergence Surface Application. After planting and 
before crop emergence, apply a uniform broadcast treat-
ment to the soil surface . Apply Surtain only to a uniform 
seedbed which is firm and free of clods, cracks, excess 
trash (previous crop residue), and weed growth . If weeds 
are present, apply Surtain in a tank mix with an

9
appro priate postemergence herbicide, for example a 
 glyphosate-containing product .
Early Postemergence Application. SurtainTM 
 herbicide must be applied and activated before weed 
seedling emergence or in a tank mixture that controls 
emerged weeds . Surtain will not control emerged weeds . 
Weeds that are already emerged at the time of application 
must be controlled with cultivation, tank mix or sequential 
application of another herbicide labeled for postemergence 
control of the target weeds in the crop .
Application Methods and Equipment
 Surtain may be applied by ground or air (fixed-wing air-
craft only, DO NOT apply by helicopter) .
Thorough spray coverage is required for optimum weed 
control and can be improved with proper adjuvant, nozzle, 
and spray volume selection . Use and configure application 
equipment to provide an adequate spray volume, an accu-
rate and uniform distribution of spray droplets over the 
treated area, and to avoid spray drift to nontarget areas . 
Adjust equipment to maintain continuous agitation during 
spraying with good mechanical or bypass agitation . Avoid 
overlaps that increase rates above the use rates specified 
in this label .
 Surtain may be applied using water or sprayable fluid 
nitrogen fertilizer solutions as the spray carrier . Additionally, 
 Surtain may be impregnated on and applied with dry bulk 
fertilizer .
Aerial Spray Carrier Volume. Use 3 or more gallons of 
water per acre . The actual minimum spray volume per acre 
is determined by the spray equipment used . Use adequate 
spray volume to provide accurate and uniform distribution 
of spray particles over the treated area .
Ground Spray Carrier Volume. Use 3 or more gallons of 
water per treated acre or 20 or more gallons of sprayable 
fluid nitrogen fertilizer per treated acre .
Mandatory Spray Drift Management
Aerial Applications
• DO NOT release spray at a height greater than 10 ft 
above the ground or crop canopy, unless a greater 
application height is necessary for pilot safety .
• Applicators are required to select a nozzle and pres -
sure that deliver a medium or coarser droplet size 
(ASABE S572) .
• When applying by airplane, use low-drift nozzles 
(straight-stream nozzles, D-8 or larger) . DO NOT use 
nozzles producing a mist droplet spray .
• The boom length must not exceed 75% of the wing-
span for airplanes . 
• Applicators must use 1/2 swath displacement upwind 
at the downwind edge of the field . 
• Nozzles must be oriented so spray is directed towards 
the back of the aircraft, parallel with the airstream, and 
never point downward more than 45 degrees .
(continued)
Mandatory Spray Drift Management 
(continued)
Aerial Applications (continued)
• DO NOT apply when wind speeds exceed 10 mph at 
the application site .
• DO NOT apply during temperature inversions .
Ground Applications
• Apply with the nozzle height recommended by the 
manufacturer, but no more than 3 ft above the ground 
or crop canopy .
• Applicators are required to select a nozzle and pres -
sure that deliver a medium or coarser droplet size 
(ASABE S572) . Flood-jet type nozzles are recommend-
ed for residual soil surface application . Nozzles that 
deliver coarse spray droplets may be used to reduce 
spray drift provided spray volume per acre (GPA) is 
increased to maintain coverage of target (i .e . soil sur-
face) . DO NOT use nozzles that produce fine 
(e .g . cone) spray droplets .
• DO NOT apply when wind speeds exceed 10 mph at 
the application site .
• DO NOT apply during temperature inversions .
Buffer Restrictions
Aerial Applications
To avoid potential adverse effects to nontarget areas, 
applicators must maintain a 160-foot buffer between 
the application area and the closest downwind edge 
of nontarget terrestrial habitats (including grasslands, 
forested areas, shelter belts, woodlots, hedgerows, 
riparian areas, shrub lands, and crop lands) .
Ground Applications
To avoid potential adverse effects to nontarget areas, 
applicators must maintain a 75-foot buffer between 
the application area and the closest downwind edge 
of nontarget terrestrial habitats (including grasslands, 
forested areas, shelter belts, woodlots, hedgerows, 
riparian areas, shrub lands, and crop lands) .
Spray Drift Advisories
The applicator is responsible for avoiding off-site spray 
drift . Be aware of nearby nontarget sites and environmen-
tal 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
Volume. Increasing the spray volume so that larger drop-
lets are produced will reduce spray drift . Use the highest 
practical spray volume for the application . If a greater spray

10
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 
must be oriented parallel with the airflow in flight .
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 must remain level with the 
crop and have minimal bounce .
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 feet 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 Inversion
Drift potential is high during a temperature inversion . Tem-
perature 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 . 
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 .
Ground Application (dry bulk fertilizer)
 SurtainTM herbicide may be impregnated or coated onto 
dry bulk granular fertilizer carriers for residual soil surface 
application . Impregnation or coating may be conducted by 
in-plant bulk or on-board systems . Perform the mixing 
operation in well-ventilated areas .
Addition of a drying agent may be necessary if the fertilizer 
and herbicide blend is too wet for uniform application 
because of high humidity, high urea concentration, or low 
fertilizer use rate . Slowly add the drying agent to the blend 
until a flowable mixture is obtained . Drying agents are not 
recommended for use with on-board impregnation 
 systems .
Under some conditions, fertilizer impregnated with Surtain 
may clog air tubes or deflector plates on pneumatic appli -
cation systems . Mineral oil may be added to Surtain 
before blending with fertilizer to reduce plugging . DO NOT 
use drying agents when mineral oil is used . To avoid sepa-
ration of Surtain and mineral oil mixes in cold 
temperatures, keep mixture heated or agitated before 
blending with fertilizer . Mineral oil may be used at in-plant 
blending stations or on-board injection systems .
Generally, fertilizer application rates of at least 200 lbs to 
700 lbs per acre of herbicide and fertilizer blend provide 
adequate distribution or coverage for Surtain across the 
soil surface . Refer to Table 5 in this label for use rates of 
Surtain to be applied on per acre basis when impregnat-
ed with fertilizer to create the dry bulk fertilizer blend for 
application . Apply uniformly to the soil to prevent possible 
crop injury and offer satisfactory weed control . Impregnat-
ed fertilizer spread at 1/2 rate and overlapped for a full rate 
offer a more uniform distribution . Use shallow (less than 
2 inches) incorporation for improved weed control . Deeper 
incorporation dilutes the herbicide layer near the soil sur -
face and may result in unsatisfactory weed control .
To calculate the herbicide rate when using dry bulk fertiliz-
er applications:
fl ozs herbicide per acre x 2000 = fl ozs herbicide
per ton of fertilizerpounds fertilizer per acre
Cleaning Spray Equipment
Clean application equipment thoroughly by using a strong 
detergent or commercial sprayer cleaner according to the 
manufacturer’s directions, followed by triple rinsing the 
equipment before and after applying this product .
Additives
Surtain is formulated to provide optimal residual pre-
emergence weed control . No additive is needed when 
 Surtain is applied alone .
However, several herbicide tank mixes with Surtain may 
require an adjuvant to improve burndown of emerged 
weeds . Therefore, depending on the timing of application 
relative to crop emergence, the following adjuvants may be 
used with Surtain tank mixes:
For applications made before crop emergence (i .e ., pre-
plant surface, preplant incorporated, or preemergence): 
non-ionic surfactant (NIS), crop oil concentrate (COC), high 
surfactant petroleum oil concentrate/blends (HSPOC), 
methylated seed oil (MSO), high surfactant methylated oil 
concentrate (HSMOC), urea ammonium nitrate (UAN) .

11
For applications made after crop emergence (i .e ., early 
postemergence): NIS at 0 .25% v/v (1 qt/100 gal) optionally 
with a spray grade ammonium sulfate (AMS) at 8 .5 to 
17 lbs/100 gallons of water . If using liquid AMS product, 
use a rate that delivers an AMS equivalent of 8 .5 to 
17 lbs/100 gallons of water . The use of COC or HSPOC 
may result in temporary crop injury . DO NOT add MSO or 
HSMOC or UAN to a SurtainTM herbicide spray mix .
When an adjuvant is to be used with this product, BASF 
recommends the use of a Chemical Producers and 
 Distributors Association (CPDA) certified adjuvant .
DO NOT add acidifying agents to the spray tank when 
applying Surtain .
Tank Mixing Information
It is the pesticide user’s responsibility to ensure that all 
products in the mixtures are registered for the intended 
use . Read and follow the applicable restrictions and limita -
tions and directions for use on all product labels involved in 
tank mixing . Users must follow the most restrictive direc-
tions for use and precautionary statements of each 
product in the tank mixture .
 Surtain may be tank mixed or applied sequentially with 
other herbicide products registered for use in any labeled 
crop found in this label for a broader spectrum of residual 
weed control and/or control of emerged weeds . Refer to 
the tank mix product labels to confirm that the respective 
tank mix products are registered for use on the labeled 
crop . Read and follow tank mix product labels for applica -
tion instructions, use restrictions and precau tions, and 
rotational cropping guidance .
Compatibility Test for Mix Components
Before mixing components, always perform a compatibility 
jar test .
1 . For 20 gallons per acre spray volume, use 3 .3 cups 
(800 mL) of water . For other spray volumes, adjust rates 
accordingly . Only use water from the intended source at 
the source temperature .
2 . Add components in the sequence indicated in the 
 Mixing Order section using 2 teaspoons for each 
pound or 1 teaspoon for each pint of labeled use rate 
per acre .
3 . Always cap the jar and invert 10 cycles between com-
ponent additions .
4 . When the components have all been added to the jar, 
let the solution stand for 15 minutes .
5 . Evaluate the solution for uniformity and stability . The 
spray solution must not have free oil on the surface, or 
fine particles that precipitate to the bottom, or thick 
(clabbered) texture . If the spray solution is not compati-
ble, repeat the compatibility test with the addition of a 
suitable compatibility agent . If the solution is then com-
patible, 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
Maintain constant agitation throughout mixing and applica -
tion until spraying is completed .
1 . Water - Fill tank 1/2 to 3/4 full with clean water and start 
agitation .
2 . Inductor - If an inductor is used, rinse it thoroughly 
after each component has been added .
3 . 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 spray tank before 
 continuing .
4 . Products that are formulated as Wettable 
 Powders, Dry Flowables, and Water Dispersible 
Granules - Add to tank and allow to fully dissolve .
5 . Water-soluble additives (including dry and liquid fer-
tilizers AMS or UAN) 
6 . Surtain - Add at this point in tank mix preparation 
process .
7 . Water-dispersible liquid products (suspension con-
centrates and suspo-emulsions, including atrazine-, 
mesotrione-, topramezone-based products)
8 . Water-soluble products (including certain glyphosate 
formulated products)
9 . Emulsifiable Concentrates
10 . Adjuvants (including NIS, COC/HSPOC, MSO/HSMOC)
11 . Remaining quantity of water
If the spray mixture is allowed to settle for any period of 
time, thorough agitation is essential to resuspend spray 
mixture before spraying is resumed . Continue agitation 
while spraying .

Application Timing
Surtain may be applied in a single application or in 
sequential applications .
Early Preplant Surface Application 
(within 15 to 30 days of planting)
Use application rates in Table 5 when making early pre-
plant surface applications, using the highest application 
rate for a given soil texture . Early preplant surface applica-
tions are not advised on coarse soils, or in areas where 
average annual rainfall (or rainfall plus irrigation) typically 
exceeds 40 inches .
Early preplant surface applications may be applied as part 
of a split application program where applications are made 
as part of the application timings described in this label . 
However, the cumulative total of sequential application 
rates must not exceed the maximum labeled rate for a 
given soil texture .
Preplant Surface and 
Preplant Incorporated Application 
(within 14 days of planting)
Apply Surtain at use rates specified in Table 5 as a 
broadcast spray to the soil surface or incorporated before 
planting on all soil types .
Preemergence Surface Application

broadcast spray to the soil surface after planting and 
before crop emergence .
Early Postemergence Application
Apply Surtain at use rates specified in Table 5 as a broad-
cast spray to field corn at spiking up to the V3 stage (visible 
third leaf collar) [Alternate text: V1 stage (visible first leaf col-
lar) or V2 stage (visible second leaf collar) or V4 stage (visible 
fourth leaf collar) or V5 stage (visible fifth leaf collar) or 
V6 stage (visible sixth leaf collar) or V8 stage (visible eighth 
leaf collar)] .
Refer to Additives section for details about adjuvants for 
applications of Surtain made after crop emergence . 
Sequential Application
If a sequential application program of Surtain is used (e .g . 
preplant followed by preemeergence application, or 
 preplant or preemergence followed by an early postemer-
gence application), the maximum combined rate of 
 Surtain that may be applied in field corn per year is 
27 .0 fl ozs/A .
Crop-specific Use in Seed Corn. Apply Surtain pre-
plant surface, preplant incorporated, preemergence, or 
early postemergence at 9 .2 fl ozs/A in seed corn across all 
soil types . Sequential applications of Surtain may be 
made with a minimum of 30 days between applications . 
DO NOT apply more than a maximum cumulative amount 
of 17 .0 fl ozs/A of Surtain per cropping season in seed 
corn . Before applying Surtain to seed corn, verify the 
selectivity of Surtain on your inbred line or hybrid with

14
your local seed company (supplier) to help avoid potential 
injury to sensitive inbreds or hybrids .
Crop-specific Restrictions
• DO NOT apply SurtainTM herbicide to popcorn or 
sweet corn .

pyrethoids .
EXCEPTION: Surtain may be applied when 
Aztec® 2.1% Granular Insecticide , AZTEC® 4.67 G 
granular insecticide , or SmartChoice ® 5G granular 
 insecticide is applied at planting as a band, T-band, or 
infurrow .
Crop-specific Precautions
• When applied before crop emergence, Surtain applica-
tion may result in delayed corn emergence and stunting 
under certain environmental conditions including cool 
temperatures, excessive rainfall/irrigation, and/or per-
sistent wet soil conditions occurring after application .
• Ensure the corn seed row is closed . Soil conditions that 
cause poor seed furrow closure and coverage may result 
in delayed corn emergence or stunting .
• Application of this product with other postemergence or 
residual herbicides may increase the potential for crop 
injury after corn has emerged .
• Early postemergence applications of Surtain may result 
in crop response symptoms consisting of foliar spotting 
on emerged leaves . Use of an adjuvant can increase the 
level of foliar spotting on emerged leaves . Refer to 
 Additives section for more details on adjuvants .
• Tank mixing of Surtain with Glufosinate formulations for 
early postemergence applications is NOT advised as 
corn injury could result .
• Early postemergence applications of Surtain should be 
made with water as the carrier . Sprayable fluid fertilizer 
as an herbicide carrier for early postemergence applica -
tions in corn can typically cause corn injury up to and 
including tissue burn (necrosis) . Sprayable fluid fertilizer 
as a carrier is NOT advised for use with Surtain after 
crop emergence unless typical fertilizer burn symptoms 
are acceptable .
• Make applications of Surtain promptly after preparing 
the spray mixture . Avoid use of spray solutions of 
 Surtain which have been allowed to stand or have been 
stored in application equipment or the mix tank for an 
extended period of time as corn injury could result .
Fallow and Postharvest Croplands
 Surtain may be used for residual control of weeds at any 
time of the year during the fallow period following crop har-
vest and before the following crop is planted .
Application Rate and Timing
Surtain may be applied in a single application or in 
sequential applications .
For residual weed control, apply Surtain at 9 .2 to 
17 .0 fl ozs/A . 
Specific rotational crop intervals must be observed 
between an application of Surtain and planting of the 
 following crop (see Crop Rotation Intervals section for 
crop rotation restrictions) .

15
Crop-specific Restrictions
