PRODUCT INFORMATION
DiFlexx® DUO is a selective preemergence and postemergence
herbicide for the control of annual broadleaf weeds; control
and/or suppression of many biennial/perennial broadleaf
weeds and control of annual grasses found in corn (field
corn, seed corn, popcorn and corn grown for silage) and for
postharvest burndown weed control. Weed growth ceases
within hours after DiFlexx DUO is applied. Symptoms on
susceptible weed species include epinastic-like symptoms
on stems and leaves with tissues turning yellow and bleached
in color and soon becoming necrotic. Plant death generally
occurs within 7 to 14 days after application.
WEED CONTROL INFORMATION
DiFlexx DUO applied postemergence at recommended rates
of 24-40 fluid ounces per acre will effectively control a broad
array of important annual broadleaf weeds and grasses,
including biotypes resistant to glyphosate-, triazine-, auxin-,
HPPD-, benzoic-, and ALS-inhibiting herbicides (Tables 1-2).
Best control of annual broadleaf weeds is achieved when
weeds are less than 6” in height and actively growing while
the best control of annual grasses is achieved prior to tillering
and when grasses are actively growing. In corn, the addition
of atrazine at a minimum 0.5 lb ai/A will improve control of
annual broadleaf weeds and increase the speed, spectrum,
and consistency of grass control. DiFlexx DUO applied
postemergence at 24-40 fluid ounces per acre will also
control or suppress many biennial/perennial broadleaf weeds
(Tables 3-4). As a preemergence application, DiFlexx DUO
will provide suppression/control of certain annual broadleaf
and grass weeds (Table 5) but will generally not provide
season-long residual weed control. Preemergence applications
of DiFlexx DUO should always be either tank mixed with
additional registered residual preemergence herbicides (see
Preemergence tank mix section) or be followed by a planned
postemergence herbicide application program for improved
weed control. Always follow the most restrictive use rates and
use instructions listed on the labeling of all tank mix partners.

Cultivation
Cultivation can help remove suppressed weeds or multiple flushing weeds. However, cultivation
should not be performed within 7 days of an application of DiFlexx DUO as this could decrease
effectiveness of weed control due to disruption of herbicide translocation in the plant.
RESISTANCE MANAGEMENT
DiFlexx DUO is a Group 4 and Group 27 herbicide. A given weed population may contain or
develop resistance to a herbicide after repeated use. Appropriate resistance-management
strategies should be followed to mitigate or delay resistance. The following Integrated Weed
Management Techniques are effective in reducing problems with herbicide resistant weed
biotypes. It is best to use multiple practices to manage or delay resistance, as no single strategy
is likely to be totally effective.
•	 Rotate crops. Crop rotation diversifies weed management.
•	 Rotate Herbicide-tolerant traits. Alternate herbicide tolerant traits and or use HT trait stacks
for more efficient rotations.
•	 Rotate and tankmix modes of action. Use tankmix partners and multiple MOAs during both
the growing season and from year to year to reduce the selection pressure of a single MOA.
•	 Know your weeds, know your field. Closely monitor problematic areas with difficult to
control weeds or dense weed populations.
•	 Start with clean fields. Effective tillage or the use of a burndown herbicide program can
control emerged weeds prior to planting.
•	 Stay clean – use residual herbicides. Regardless of tillage system, a preemergence or early
postemergence soil – applied residual herbicide should be used.
•	 Apply herbicides correctly. Ensure proper application, correct timing, full-use rates and
appropriate spray volumes.
•	 Control weed escapes. Consider spot herbicide application, row wicking, cultivation, hand
removal of weeds or other techniques to stop weed seed production and improve weed
management.
•	 Zero Tolerance –  reduce the weed seed bank. Do not allow surviving weeds to set seed,
which will help decrease weed populations from year to year and prevent major weed shifts.
•	 Clean Equipment. Prevent the spread of herbicide resistant weeds and seeds.
Contact your local extension specialist, certified crop advisory and /or Bayer CropScience
representative (1-844-RRXtend) for additional resistance management or IPM recommendation.
Also for more information on Weed Resistance Management, visit the Herbicide Resistance
Action Committee (HRAC) on the web at http://www.hracglobal.com.
ROTATIONAL CROP RESTRICTIONS
The interval between application and planting rotational crops is shown in Table 6. If a corn
crop has been destroyed by hail or other means soon after a DiFlexx DUO application, field corn,
seed corn, popcorn and corn grown for silage may be replanted immediately. Other crops may
be replanted at the intervals specified in Table 6. Planting rotational crops at intervals less than
those specified in Table 6 may result in crop injury. Moisture is essential for the degradation
of this herbicide in soil. If dry weather prevails, use cultivation to allow herbicide contact with
moist soiI.

1 Cumulative precipitation between application of DiFlexx DUO  and replanting to sugar beets or
dry beans must total 20 inches. Furrow or flood irrigation cannot be included in the total. The
amount of cumulative precipitation required before planting a rotational crop is in addition to
the required rotational interval given in months.
2 Thorough tillage should follow the crop in which DiFlexx DUO was used and precede the rotation
to sugar beets.
3 This plantback interval requires that onion crops be grown under irrigated conditions. The
plantback interval for non-irrigated onion is 18 months
4 All other crops may be seeded only after the completion of a successful bioassay after a DiFlexx
DUO application. Refer to the “Field/small scale bioassay” section.
COVER CROPS
Use of cover crops as a means of soil improvement, erosion control, weed and/or insect
suppression, etc., following harvest of corn in the fall is increasing. Planting of cover crops
in fields treated with DiFlexx DUO is allowed as long as these cover crops are not grazed by
livestock nor harvested for food. Cover crops are to be tilled under or chemically controlled
with burndown herbicides in the spring. Cover crops can be planted within 90-120 days after
application of DiFlexx DUO. However, all potential cover crops have not been evaluated for
tolerance to DiFlexx DUO and significant injury may occur. Prior to seeding a cover crop, complete
a successful field/ small scale bioassay to provide an indication of the level of tolerance to the
prior DiFlexx DUO application. Refer to the “Field/ Small Scale Bioassay” section. If used in tank
mixtures with other herbicides, always follow the most restrictive label.
FIELD/SMALL SCALE BIOASSAY
A field/ small scale bioassay must be completed before rotating to a cover crop other than those
specified in the “Rotational Crop Restrictions” section of this label. To conduct an effective field
bioassay, grow strips of the crop(s) you intend to grow the following season in a field previously
treated with DiFlexx DUO. The test strip should be placed in a controlled area and should include
low areas and knolls, and include variations in soil such as type and pH. Crop response to the
bioassay will determine if the crop(s) grown in the test strips can be grown safely in the areas
previously treated with DiFlexx DUO.
For an effective small scale bioassay, collect uniform samples of all soil types from the
DiFlexx DUO - treated field (see example above for types of soil in the sample) and place the
soil into a sturdy container. Plant the desired cover crop into the soil, apply water and place the
container in a warm, sunny area to allow germination and growth of the crop. Monitor growth of
the cover crop over a three to four week period. If the cover crop emerges and grows normally,
the risk to establish and grow the cover crop in the DiFlexx DUO -treated field should be tolerable.
SPRAY DRIFT MANAGEMENT
Spray drift may result in injury to non-target crops or vegetation. To avoid spray drift, DO NOT
apply when wind speed is greater than 10 MPH or during periods of temperature inversions.
DO NOT apply when weather conditions, wind speed or wind direction may cause spray drift
to non-target areas.
AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR.
Sensitive Areas
Only apply this product 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 10 MPH or less and is blowing away from sensitive areas).
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.
DO NOT apply under circumstances where possible drift to unprotected persons, or to food,
forage, or other plantings that might be damaged, as crops thereof may be rendered unfit for
sale, use or consumption.
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 still provide sufficient weed coverage
and control. Applying larger droplets will reduce drift potential, but will not prevent drift if
applications are made improperly, or under unfavorable environmental conditions (see Wind,
Temperature and Humidity, and Temperature Inversion sections below).
Uniform, thorough spray coverage is important to achieve consistent weed control. Select nozzles
and pressure that deliver MEDIUM spray droplets as indicated in nozzle manufacturer’s catalogs
and in accordance with ASAE Standard S-572. 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 weeds.
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 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.
Application Height
For ground boom applications, apply with nozzle height no more than 15 inches above the ground
or crop canopy.

Wind
Drift potential is lowest between wind speeds of 2 - 10 mph.
However, many factors, including droplet size and equipment
type determine drift potential at any given speed. NOTE: Local
terrain can influence wind patterns. Every applicator should
be familiar with local wind patterns and how they affect spray
drift.
Temperature and Humidity
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. Avoid spraying during
conditions of low humidity and/or high temperatures.
Temperature Inversion
Do not make applications into areas of temperature inversion.
Temperature inversion restricts 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 inversion. Temperature
inversion is characterized by an increasing temperature with
altitude and is common on nights with limited cloud cover and
light to no wind. It begins to form as the sun sets and often
continues into the morning. Its presence can be indicated by
ground fog; however, if fog is not present, inversion can also
be identified by the movement of smoke from a ground source.
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.
APPLICATION INFORMATION
DiFlexx DUO may be applied either preplant/preemergence
burndown, preemergence or postemergence by ground
equipment only. DO NOT apply DiFlexx DUO by air or through
any type of irrigation system. Use application equipment that
will provide uniform, thorough spray coverage of weed foliage
to achieve consistent weed control. DiFlexx DUO mixtures
should be sprayed within 24 hours of mixing to avoid product
degradation. DiFlexx DUO is rain fast within 4 hours after
application to most weed species.
WATER VOLUME AND NOZZLES
DiFlexx DUO can be applied using a minimum of 10 gallons of
water per acre (unless a higher volume is specified for a tank-
mix partner). For weed control in dense weed populations or
under adverse growing conditions, 15 to 20 gallons of water per
acre is recommended. Good coverage is essential to achieve
optimum weed control.
Select nozzles and a spray pressure that deliver MEDIUM
spray droplets as indicated in nozzle manufacturer’s catalogs
and in accordance with ASAE Standard S-572. 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 weeds. Flat fan nozzles of 80° or 110°
are recommended for optimum postemergence coverage.
Typically, flat-fan nozzles operated at 30-60 PSI will deliver
MEDIUM spray droplets, providing optimum spray coverage and
canopy penetration. Lower pressure operation and/or higher
volume flat fan nozzles typically deliver COARSE sprays. Refer
to nozzle manufacturer catalogs.
•	 Boom height should be based on the height of the crop
– at least 15 inches above the crop canopy.
•	 Air induction nozzles should be used at or near 80 psi to
produce a medium droplet size.
•	 Proper agitation should be maintained within the tank to
keep the product dispersed.
•	 See the Spray Drift Management section of this label for
additional information on proper application of DiFlexx
DUO.
DO NOT use nozzles that produce FINE (e.g. - Cone) or EXTRA
COARSE (e.g. - Flood jet) spray droplets.
COMPATIBILITY TESTING OF MIXTURES
If DiFlexx DUO is to be tank mixed with other pesticides,
compatibility must be tested prior to mixing. To test for
compatibility, use a small container and mix a small amount
(0.5 to 1qt) of spray, combining all ingredients in the same
ratio as the anticipated use. If any indications of physical
incompatibility develop, do not use this mixture for spraying.
Indications of incompatibility usually occur within 5-15 minutes
after mixing. If the mixture balls-up, forms flakes, sludges, gels,
oily film or layers, or other precipitates, it is not compatible and
the tank mix combination should not be used.
SPRAY TANK MIXING INSTRUCTIONS
DiFlexx DUO must be applied with clean and properly calibrated
equipment. Prior to adding DiFlexx DUO, ensure that the spray
tank, filters and nozzles have been thoroughly cleaned and that
agitation system is properly working.
1. Fill spray tank with 50% of the required volume of water,
and begin agitation.
2. Agitate the DiFlexx DUO product container thoroughly
by shaking, circulating or stirring prior to adding the
herbicide into the spray tank.
3. Add the appropriate amount of DiFlexx DUO slowly to
the spray tank or mixing system and ensure complete
dispersion. Maintain and ensure thorough dispersion and
sufficient agitation during both mixing and spraying.
4. If tank mixing with another pesticide, add the tank mix
product next.
5. Add the adjuvant.
6. Fill the spray tank with balance of water needed.
SPRAY ADDITIVES
DiFlexx DUO is a suspension concentrate that requires the use
of an external surfactant to achieve optimum weed control
when applied postemergence or when applied preplant or
preemergence if weeds are present. Agriculturally approved
drift reducing additives may also be used.
Surfactant
The use of a Methylated Seed Oil (MSO) or Crop Oil Concentrate
(COC) is recommended when DiFlexx DUO is used or when
alternative adjuvants are not otherwise specified on this label.
MSO or COC can improve control of weeds under stress, in high
populations, in mixed grass and broadleaf weed populations,
and under conditions of low humidity. Use MSO or COC at
1 gallon per 100 gallons of water (1% v/v). The MSO or COC
should contain at least 80% MSO or COC and 10% emulsifier
or greater.
As an alternative to traditional MSO or COC surfactants, High
Surfactant oil Concentrates (HSOC) at recommended rates may
be used with DiFlexx DUO. An HSOC is an emulsifiable oil based
product containing 25-50% surfactant (wt/wt) in a minimum of
50% oil (wt/wt). The oil concentrates in HSOC can be based on
MSO or COC. MSO or COC based products are preferred with
DiFlexx DUO particularly when used alone or with atrazine.

PRECAUTIONS FOR USE
•	 DiFlexx DUO mixtures should be sprayed within
 24 hours of mixing to avoid product degradation.
•	 DiFlexx DUO is rain fast within 4 hours after application
to most weed species.
•	 DiFlexx DUO Herbicide weed control may be reduced if:
o Rainfall occurs within 4 hours of application
o Weeds are dust covered or in the presence
of heavy dew, fog, and mist/rain at time of
application
•	 Weeds are stressed and not actively growing due to
drought, heat, lack of fertility, flooding, or prolonged
cool temperatures at time of application
•	 Avoid drift of DiFlexx DUO onto adjacent crops.
•	 Refer to the Resistance Management section of this
label for specific precautions to help prevent weed
resistance to this product.
RESTRICTIONS FOR USE
•	 DO NOT apply when wind causes drift to off-site
vegetation as injury may occur. DiFlexx DUO delivered
via drift or tank contamination can cause severe
damage to other crops. Careful management of spray
drift and tank cleanout is required.
•	 DO NOT apply DiFlexx DUO with liquid fertilizers as the
primary spray carrier. Only apply with water as the
primary spray carrier plus recommended adjuvants.
•	 DO NOT apply DiFlexx DUO by air or through any type
of irrigation system.
SPECIFIC CROP USE DIRECTIONS
USE DIRECTIONS
DiFlexx DUO can be applied by ground equipment for
preplant/preemergence burndown, preemergence or
postemergence weed control in field corn, seed corn, popcorn
and corn grown for silage. DiFlexx DUO is not for use on sweet
corn. Best results are obtained when the product is applied
postemergence to young, actively growing weeds. DiFlexx DUO
will affect weeds that are larger than the recommended height;
however it may result in incomplete weed control.
DiFlexx DUO should be a part of an integrated pest control
program that may include herbicides, insecticides and/or
fungicide applied prior to, in tank mix with, or following a
DiFlexx DUO application. When using tank mix or sequential
applications with DiFlexx DUO, always follow the companion
product label to determine specific use rates, application
timings and pests controlled. In addition, follow precautions
and restrictions including state and local use restrictions that
may apply to specific products. Always follow the directions of
the most restrictive label.
 CORN Specific Precautions and Restrictions
•	 Corn (field seed, pop and silage) can be planted
immediately after an application of DiFlexx DUO. DO
NOT plant other rotational crops immediately following
DiFlexx DUO application. For all other crops refer to the
Rotational Crop Restrictions section of this label.
•	 Plant corn at least 1 ½ inches deep. Corn seed must be
completely covered with soil and furrow firmed.
•	 In rare instances, applications of DiFlexx DUO during
periods of rapid growth may result in temporary leaning
of the crop. Corn will usually become erect within
 3 - 7 days. Cultivation should be delayed until after the
 corn is growing normally to avoid potential stalk breakage.
•	 Seed Corn and Popcorn Only - Herbicide sensitivity in all
hybrids and inbreeds of seed corn and popcorn has not
been tested. Consult with your seed provider for advice
on hybrid/inbred tolerance before applying DiFlexx DUO.
If the tolerance of a hybrid/inbred is not known, apply
DiFlexx DUO to a small area to first determine if the
hybrid/inbred is tolerant prior to spraying large acreages
of that hybrid/inbred.
•	 DiFlexx DUO may be apply up to 40 fl oz/A per acre per
application.
•	 The maximum seasonal rate of DiFlexx DUO which can be
applied is 78 fl oz/A per use season.
•	 DO NOT apply DiFlexx DUO to corn that exhibits injury
from previous herbicide applications.
•	 DO NOT apply DiFlexx DUO with liquid fertilizers as the
primary spray carrier.
•	 DO NOT apply more than two (2) applications of DiFlexx
DUO per use season.
•	 DO NOT graze or harvest corn forage within 45 days
of the final DiFlexx DUO application. Corn grain and
stover may be harvested once the crop has reached the
ensilage (milk) stage.
POSTEMERGENCE APPLICATION
Use Rates
Apply DiFlexx DUO postemergence at 24 - 40 fluid ounces per
acre per application. Always add the appropriate adjuvants to
the spray tank (see SPRAY ADDITIVES section of this label). Use
the higher application rates when one or more of the following
situations are present in the fields to be treated:
•	 Weeds present have suspected/confirmed resistance
to either Group 4 (Auxin) or Group 27 (HPPD)
 mode-of-action herbicides.
•	 Heavy weed populations.
•	 Biennenial/perennial weeds listed on the label.
•	 Annual weeds taller than 6 inches.
Applications of DiFlexx DUO at rates less than recommended
rates may result in incomplete weed control and reduction in
residual activity.
Application Method, Timing and Number of Sprays
•	 Broadcast Application: DiFlexx DUO may be applied to
corn as a broadcast spray application from emergence
up to, but not including, the V7 stage of growth (seventh
leaf collar) or 36” tall, whichever occurs first.
•	 Directed Application : DiFlexx DUO should be applied
as a directed spray application when corn is from the
V7 thru V10 stages of growth (7-10 collars), up to 36”
tall, or up to 15 days prior to tassel, whichever occurs
first. Directed sprays should also be used if corn leaves
prevent proper spray coverage, sensitive crops are
grown nearby or when tank mixing with 2, 4-D.
•	 Sequential Application : A maximum of two (2)
applications of DiFlexx DUO may be applied per growing
season. Sequential applications must be separated by a
minimum of two (2) weeks.
Tank Mixtures for Weed Control
To provide a broader spectrum of weed control in corn, DiFlexx
DUO may be applied in tank mixtures with but not limited to the
following herbicides:
•	 Atrazine
An application of DiFlexx DUO in combination with
atrazine at 0.5 lb ai/A will increase the speed of control,
weed spectrum and consistency of control. Do not use
atrazine if corn is greater than 12 inches tall.
•	 Glyphosate (including Roundup and Touchdown
branded products)
DiFlexx DUO can be tank mixed with glyphosate for use
on glyphosate-tolerant corn. DiFlexx DUO will enhance
control of broadleaf and glyphosate-resistant weeds,
and will reduce glyphosate induced weed shifts.
•	 If resistant weeds are present or suspected, the use
of an additional adjuvant may be necessary with
glyphosate. Under these circumstances, please refer to
the SPRAY ADDITIVE – Surfactant section of this label.
It is the pesticide user’s responsibility to ensure that all
products in the listed mixtures are registered for the intended
use. Users must follow the most restrictive directions for use
and precautionary statements of each product in the tank
mixture.
Tank Mixtures for Insect Control
To provide weed and insect control in corn, DiFlexx DUO may
be used sequentially with all soil-applied insecticides or used
sequentially or in tank mix with most foliar-applied insecticides
including Baythroid ® XL, Oberon ®, and other registered foliar
insecticides. DO NOT apply DiFlexx DUO in tank mixtures with
Lorsban® /chlorpyrifos insecticide. If DiFlexx DUO is used
sequentially with foliar insecticides, applications should be
separated by at least 7 days.
It is the pesticide user’s responsibility to ensure that all
products in the listed mixtures are registered for the intended
use. Users must follow the most restrictive directions for use
and precautionary statements of each product in the tank
mixture.

Tank Mixtures for Disease Control
To provide weed and disease control in corn, DiFlexx DUO
may be mixed with most foliar-applied fungicides including
Stratego® YLD, Proline ® and Prosaro ® and other registered
fungicides.
It is the pesticide user’s responsibility to ensure that all
products in the listed mixtures are registered for the intended
use. Users must follow the most restrictive directions for use
and precautionary statements of each product in the tank
mixture.
PREPLANT/PREEMERGENCE APPLICATION
Preplant/preemergence applications of DiFlexx DUO may be
made in either conventional, conservation tillage or no-till
cropping systems.
Use Rates
Apply DiFlexx DUO at 32 - 40 fluid ounces per acre per
application. Use the higher application rate when one or more
of the following situations are present in the fields to be treated:
•	 Weeds present have suspected/confirmed resistance to
either Group 4 (Auxin) or Group 27 (HPPD)
 modes-of-action herbicides.
•	 Heavy weed populations.
DiFlexx DUO will provide early season suppression/control
of certain broadleaf and grass weeds (see Table 5) but will
generally not provide season-long residual weed control.
Preplant/preemergence applications of DiFlexx DUO should
always be either tank mixed with additional registered
residual preemergence herbicides or be followed by a planned
postemergence herbicide application program.
 Application Method, Timing and Number of Sprays
•	 Preplant/Preemergence Burndown: When weeds
are present at the time of treatment and prior to corn
emergence, a tank mixture of DiFlexx DUO with MOS or
COC is recommended for burndown of labeled weeds
6” or less in height. When weeds are greater than
 6” in height or weeds not controlled by DiFlexx DUO
 are present, the addition of a burndown herbicide such
 as glyphosate is recommended. Addition of atrazine
 will also provide improved weed control.
•	 Preemergence:  Apply DiFlexx DUO during planting
(behind the planter after furrow closure) or after
planting, but before weeds emerge. Failure to
thoroughly close and firm the seed furrow may allow
herbicide to directly contact the seed which can cause
injury.
•	 Sequential Application: A maximum of two
 (2) applications of DiFlexx DUO may be
 applied per growing season. Sequential applications
 must be separated by a minimum of two (2) weeks.
Tank Mixtures for Weed Control
DiFlexx DUO at 32 - 40 fluid ounces per acre may be used in a
tankmixture with atrazine to improve spectrum and consistency
of weed control wherever atrazine use is permitted and
appropriate. It may also be used with any additional registered
preemergence herbicide for use in corn. Always follow the
companion product label to determine specific use rates,
application timings and pests controlled. In addition, follow
precautions and restrictions including state and local use
restrictions that may apply to specific products. Always follow
the directions of the most restrictive label.
POST HARVEST BURNDOWN APPLICATION
DiFlexx DUO may be used as a postharvest burndown
treatment to control broadleaf weeds at any time of the
year following harvest of corn or before planting of the next
rotational crop. DiFlexx DUO will be especially effective against
broadleaf weed biotypes which have developed resistance to
glyphosate-, triazine-, ALS-inhibiting, auxin- and other
herbicide modes-of-action. Specific rotational crop intervals
must be observed between the postharvest application of
DiFlexx DUO and planting of the next rotated crop. Refer to
the ROTATIONAL CROP section of this label for specific crop
rotation intervals.
Application Rates and Timings
Apply DiFlexx DUO as a broadcast postemergence spray at
24-40 fluid ounces per acre plus recommended adjuvant
system (refer to the SPRAY ADDITIVES information section of
this label. Best weed control will be achieved when applications
are made to young, actively growing weeds (refer to the WEED
CONTROL TABLES 1-4 section for a complete listing of weeds
controlled/suppressed). Use the higher application rates when
one or more of the following situations are present in the fields
to be treated:
•	 Weeds present have suspected/confirmed resistance to
either Group 4 (Auxin) or Group 27 (HPPD)
 modes-of-action herbicides.
•	 Heavy weed populations.
•	 Biennenial/perennial weeds listed on the label.
•	 Annual weeds taller than 6 inches.
Post Harvest Specific Precautions
•	 If applying DiFlexx DUO postharvest, only corn (field,
seed and pop) may be planted immediately. Refer to
the ROTATIONAL CROP section of this label for specific
crop rotation intervals.
Post Harvest Specific Restrictions
•	 DO NOT apply more than two (2) applications of DiFlexx
DUO per use season.
•	 DO NOT exceed a maximum seasonal cumulative
amount of 78 fluid ounces per acre of DiFlexx DUO per
use season.
•	 DO NOT graze livestock or harvest corn forage within
 45 days of application.
Tank Mixture Recommendations
Certain tank mixtures may aid in the performance of
DiFlexx DUO as a postharvest spray application. DiFlexx DUO at
24-40 fluid ounces per acre may be tank mixed with the
following herbicides or other registered postharvest herbicides
at their labeled use rates:
