PRODUCT INFORMATION

DuPont™ BL3 uses:

 BL3 provides residual control of susceptible weeds.
 BL3 provides additional burndown activity when used as part of a burndown program.
 BL3 may be applied as part of a fall burndown prog ram for control of susceptible winter annuals.
 Read tank mix product label for rates and weeds controlled. Always read and follow label directions
for all tank mix products before using. The most restrictive labeling of any tank mix product must be
followed. BL3, when applied according to label use directions, will control the weeds claimed in crop
specific use directions. This label makes no claims concerning control of other weed species.
 It is the pesticide user's responsibility to ensure t hat 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.

BIOLOGICAL ACTIVITY

BL3 needs rainfall or irrigation to activate. BL3 will form a weed barrier, cultivation after application will
reduce this weed barrier. BL3 inhibits the synthesis of a precursor of chlorophyll, causing rapid
destruction of contacted tissue.
 Crop injury may occur from applications made to poorly drained soils and/or applications made under
cool, wet conditions.
 Risk of crop injury can be minimized by using on well drained soils, planting at least 15 inches deep,
using high quality seed and completely covering seeds with soil prior to preemergence applications.
 Treated soil that is splashed onto newly emerged crops may result in temporary crop injury.
 Moisture is necessary to activate BL3 in soil for residual weed control.
 Dry weather following applications of BL3 may reduce effectiveness. However, when adequate
moisture is received after dry conditions, BL3 will control susceptible germinating weeds. BL3 may
not control weeds that germinate after application but before an activating rainfall/irrigation or weeds
that germinate through cracks resulting from dry soil.
 When adequate moisture is not received after a BL3 application, weed control may be improved by
irrigation with at least 1/4 inch of water. If emerged weeds are controlled by cultivation, residual weed
control will be reduced.

RESTRICTIONS

 Do not apply this product when weather conditions favor spray drift from treated areas.
 Do not apply during low-level inversion conditions, including fog.
 When applying by air, observe drift management restrictions and precautions listed under "AERIAL
APPLICATION".
 Do not apply to frozen or snow covered soil.
 Do not apply to farm alleys or roads where traffic may result in treated dust settling onto crops or
other desirable vegetation.
 Do not apply this product by air within 40 feet of non-target plants including non-target crops.
 Do not apply this product by air within 100 feet of emerged cotton crops.
 Do not apply this product by air within 40 feet of streams, wetlands, marshes, ponds, lakes and
reservoirs.
 Do not apply this product by air when wind velocity is less than 2 mph or more than 10 mph.
 Do not apply during a temperature inversion, when winds are gusty, or when other conditions could
produce poor coverage and/or off-target spray movement.
 Do not apply within 300 ya rds of non-dormant pears.

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 8

 Do not apply to powdery soils or soils that are susceptible to wind displacement unless irrigation can
be applied immediately after application.
 Do not apply directly to water, to areas where surf ace 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 contaminate water when disposing of equipment washwaters.
 For burndown applications prior to crop emergence do not use flood jet nozzles.
 Do not perform any tillage operation after applicat ion or residual weed control will be reduced.
 Do not apply DuPont™ BL3 when weeds are under stress due to drought, excessive water, extremes
in temperature, disease or low humidity.

PRECAUTIONS

 Mechanical incorporation into the soil will reduce residual weed control.
 Calibrate sprayers only with cl ean water away from the well site.
 Mix only enough product for the job at h and and avoid overfilling of spray tank.
 When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix.
 Thoroughly clean BL3 from application equipment imm ediately after use and prior to spraying crops.
 Failure to remove even small amounts of BL3 from application equipment may result in injury to
subsequently sprayed crops.
 Prevent drift of spray to desirable plants.
 Keep from contact with fertilizers, insect icides, fungicides and seeds during storage.
 Spray equipment used to apply BL3 should not be us ed to apply other materials to any crop foliage,
unless the proper cleanout procedures are followed. See "SPRAYER CLEANUP" for more
information.

WEED RESISTANCE

BL3, which contains the active ingredient flumioxazin, is a Group 14 herbicide based on the mode of
action classification system of the Weed Science Society of America.

When herbicides with mode of action classifications that affect the same biological sites of action are
used repeatedly over several years to control the same weed species in the same treatment area,
naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and
become dominant in that area. Adequate control of these resistant weed biotypes cannot be expected. If
weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a
different biological site of action.

To better manage herbicide resistance through delaying the proliferation and possible dominance of
herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between
crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential
herbicide applications that have a different site of action. Weed escapes that are allowed to go to seed
will promote the spread of resistant biotypes.

It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information
on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator,
and/or appropriate state agricultural extension service representative to determine appropriate actions for
treating specific resistant weed biotypes in your area.

INTEGRATED PEST MANAGEMENT

BL3 should be integrated into an overall weed and pest management strategy whenever the use of a
herbicide is required. Follow practices known to reduce weed development (tillage, crop competition) and

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 9

herbicide use (weed scouting, proper application timing, banding) wherever possible. Consult local
agricultural and weed authorities for additional IPM strategies established for your area.

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 consultant or other qualified authorities to
determine appropriate action treatment threshold levels for treating specific pest / crop systems in your
area.

APPLICATION INFORMATION

Burndown Application

For best results, apply BL3 as part of a burndown program to actively growing weeds. Applying BL3
under conditions that do not promote active weed growth will reduce herbicide effectiveness. Do not apply
BL3 when weeds are under stress due to drought, excessive water, extremes in temperature, disease or
low humidity. Weeds under stress tend to become less susceptible to herbicidal action. BL3 is most
effective when applied under warm sunny conditions.

Reduced residual weed control may occur when burndown applications are made to fields where heavy
crop and/or weed residue exist.

Rainfastness

DuPont™ BL3 is rainfast one hour after application. Do not apply if rain is expected within one hour of
application or postemergence efficacy may be reduced.

Soil Characteristics

Application of BL3 to soils with high organic matter and/or high clay content may require higher dosages
than soils with low organic matter and/or low clay content. Application to cloddy seedbeds can result in
reduced weed control.

HERBICIDE RATE

Residual Weed Control (Including Preemergence Applications or Applications as Part of a Fall or
Spring Burndown and Fallow Seedbed Program)

Based upon soil characteristics (organic matter content and texture), the most difficult to control weed
species being targeted, and the crop being grown, select the proper BL3 dosage from the rate range
tables contained in this label.

CARRIER VOLUME AND SPRAY PRESSURE GROUND EQUIPMENT ONLY.

Preemergence Application (Conventional Tillage)

To ensure uniform coverage, use 10 to 30 gallons of spray solution per acre for conventional tillage
applications. Nozzle selection must meet manufacturer's gallonage and pressure specifications for
preemergence herbicide application.

Burndown Application (Prior to Crop Emergence)

To ensure thorough coverage in burndown applications, use 15 to 60 gallons spray solution per acre. Use

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 10

20 to 60 gallons per acre if dense vegetation or heavy crop residue is present. Nozzle selection must
meet manufacturer's gallonage and pressure specifications for postemergence herbicide application. Do
not use flood jet nozzles.

See Information for Aerial Equipment under "AERIAL APPLICATION".

SPRAY ADDITIVES

Burndown Application (Prior to Crop Emergence)

Postemergence control of weeds from BL3 tank mixes will require the addition of an agronomically
approved adjuvant to the spray mixture. When an adjuvant is to be used with BL3, DuPont Corteva
Agriscience recommends the use of a Chemical Producers and Distributors Association certified adjuvant.
Either a crop oil concentrate (COC) or methylated seed oil (MSO) which contains at least 15% emulsifiers
and 80% oil or a non-ionic surfactant (NIS) at 0.25% v/v, may be used when applying BL3 as part of a
burndown program. Some tank mix partners, such as DuPont™ Abundit® Edge herbicide, are formulated
with sufficient adjuvants and do not require the addition of a crop oil concentrate, methylated seed oil or
non-ionic surfactant when tank mixed with BL3. The addition of a crop oil concentrate or methylated seed
oil may increase the burndown activity on certain weeds such as cutleaf eveningprimrose and Carolina
geranium. Verify mixing compatibility qualities by a jar test.

A spray grade nitrogen source (either ammonium sulfate (AMS) at 2 to 2.5 lbs/acre or a 28 to 32%
nitrogen solution at 1 to 2 qts/acre) may be added to the spray mixture along with either a crop oil
concentrate, methylated seed oil or non-ionic surfactant to enhance weed control. The addition of a
nitrogen source does not replace the need for a crop oil concentrate, a methylated seed oil or a non-ionic
surfactant.

JAR TEST TO DETERMINE COMPATIBILITY OF ADJUVANTS AND BL3

When using BL3 and an adjuvant, such as in stale seed bed or reduced tillage situations. Perform a jar
test before mixing commercial quantities of BL3, when using BL3 for the first time, when using new
adjuvants or when a new water source is being used.

1. Add 1 pint of the water to a quart jar. Use water from the same source and temperature as which will
be used in the spray tank mixing operation.
2. Add 1 gram of BL3 to the quart jar for every 3 ou nces of BL3 per acre being applied, gently mix until
product goes into suspension.
3. Add 60 milliliters (4 Tbsps or 2 fl oz) of the crop o il or methylated seed oil to the quart jar or 1 milliliter
of non-ionic surfactant if it is being used in place of oil, gently mix.
4. If nitrogen is being used, add 16 milliliters (1 Tbsp or 0.5 oz) of the 28 to 32% nitrogen source to the
quart jar. If ammonium sulfate is being used, add 19 grams AMS to the quart jar in place of the 28 to
32% nitrogen.
5. Place cap on jar, invert 10 times, let stand for 15 minutes, evaluate.
6. An ideal tank mix combination will be uniform an d free of suspended particles. If any of the following
conditions are observed, question the choice of adjuvant:
a) Layer of oil or globules on the mixture's surface.
b) Flocculation: fine particles in suspension or as a layer on the bottom of the jar.
c) Clabbering: thickening texture (coagulated) like gelatin.

SPRAY TANK PREPARATION

It is important that spray equipment is clean and free of existing pesticide deposits before using DuPont™
BL3. Follow the spray tank cleanout procedures specified on the label of product previously sprayed. If no
cleanout procedure is provided, follow the cleanout procedure below for all application equipment.

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 11

1. Thoroughly rinse sprayer, tanks, boom, and hoses with clean water.
2. Partially fill the tank with water and add one of the cleaning agents listed in the SPRAYER CLEANUP
section of this label. Complete filling the tank and flush the cleaning solution through the boom and
hoses. Let stand for 15 minutes with agitation or recirculation and then drain the tank after flushing
the hoses, boom, and nozzles.
3. Thoroughly rinse sprayer, tanks, boom, and hoses with clean water.
4. Follow label directions of the product previously sprayed for rinsate disposal.

During an extended period where spraying or mixing equipment will be used to apply multiple loads of
BL3, at the end of each day of spraying partially fill the tank with fresh water, flush the boom and hoses
and allow to sit overnight. A steam cleaning of aerial spray tanks is recommended to dislodge any visible
pesticide deposits.

MIXING INSTRUCTIONS

1. Fill clean spray tank 1/2 to 2/3 of desired level with clean water.
2. If a drift retardant is to be used, add 10 lbs of spray grade ammonium sulfate per 100 gals. of spray
solution.
3. To ensure a uniform spray mixture, pre-slurry the required amount of BL3 with water prior to addition
to the spray tank. Use a minimum of 1 gallon of water per ounces of BL3.
4. While agitating, slowly add the pre-slurried BL3 to the spray tank. Agitation should create a rippling or
rolling action on the water surface.
5. If tank mixing BL3 with other labeled herbicid es, add water soluble bags first, followed by dry
formulations, flowables, emulsifiable concentrates and then solutions. Prepare no more spray mixture
than is required for the immediate spray operation.
6. Add any required adjuvants.
7. Fill spray tank to desired level with water. Continue agitation until all spray solution has been
applied.
8. Mix only the amount of spray solution that can be applied the day of mixing. Apply BL3 within 6 hours
of mixing.

SPRAYER CLEANUP

To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment
immediately following applications of BL3 as follows:

Spray equipment, including mixing vessels and nurse tanks, must be cleaned each day following BL3
application. After BL3 is applied, use the following steps to clean the spray equipment:

1. Drain the tank and thoroughly hose down the interior surfaces. Flush tank, boom, and hoses with
clean water for a minimum of 5 minutes.
2. Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3%
active) for every 100 gallons of water. Complete filling the tank with water, then flush the cleaning
solution through the boom, hoses, and nozzles. Add more water to completely fill the tank and allow
to agitate or recirculate for at least 15 minutes. Again, flush the boom, hoses and nozzles, and drain
the tank.
3. Remove the nozzles, screens and the end caps of sprayer booms and clean separately in a bucket
containing water and the cleaning agent.
4. Repeat Step 2.
5. Thoroughly rinse the tank with clean water for a minimum of 5 minutes, flushing water through the
boom and hoses.
6. To enhance removal of flumioxazin from the spra y system before spraying susceptible crops, follow
the above clean-out steps with ammonia, then add a tank cleaner such as "Valent Tank Cleaner"
from Valent U.S.A. Corporation, and allow the cleaning solution to remain in the pressurized spray
system (spray tank, hoses and boom) overnight before flushing the system for a minimum of 15

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 12

minutes. If using "Valent Tank Cleaner" follow use instructions and personal protective equipment
(PPE) instructions as found on the "Valent Tank Cleaner" label.

*Equivalent amounts of an alternate strength ammonia solution or a tank cleaner recommended in
separately published DuPont company bulletins may be used.

APPLICATION EQUIPMENT

Application equipment must be clean and in good repair. Nozzles must be uniformly spaced on boom and
frequently checked for accuracy.

BROADCAST APPLICATION

Apply BL3, and BL3 tank mixes, with ground equipment using standard commercial sprayers equipped
with flat fan or flood nozzles (preemergence applications only) designed to deliver the desired spray
pressure and spray volume.

BAND APPLICATION

When banding, use proportionately less water and DuPont™ BL3 per acre. The rate of BL3 required per
acre, when applied as a banded application, can be calculated with the following formula:

Amount Needed per Acre for = Band Width in Inches X Rate per Broadcast Acre
Banded Application Row Width in Inches

AERIAL APPLICATION

Spray drift away from the site of application may cause damage to non-target vegetation. To minimize
drift, apply the largest droplet size consistent with uniform coverage and satisfactory weed control. To
obtain satisfactory application and avoid drift, the following directions must be observed:

 Do not apply during low-level inversion conditions (including fog), when winds are gusty or under
other conditions that favor drift. Do not spray when wind velocity is less than 2 mph or more than 10
mph.
 Do not apply this product by air within 40 feet of non-target plants including non-target crops.
 Do not apply this product by air within 100 feet of emerged cotton crops.
 Do not apply this product by air within 40 feet of streams, wetlands, marshes, ponds, lakes and
reservoirs.
 Carrier Volume and Spray Pressure: When used as part of a burndown weed control program,
apply BL3 in 7 to 10 gallons of water per acre. Application at less than 7 gallons per acre may provide
inadequate control. When used for preemergence weed control, apply BL3 in 5 to 10 gallons of water
per acre. The higher gallonage applications generally afford more consistent weed control. Do not
exceed the nozzle manufacturer's specified 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.
 Nozzle Selection and Orientation: Formation of very small drops may be minimized by appropriate
nozzle selection, by orienting nozzles away from the air stream as much as possible and by avoiding
excessive spray pressure. Use nozzles that produce flat or hollow cone spray patterns. Use non-drip
type nozzles, such as diaphragm type nozzles, to avoid unwanted discharge of spray solution. The
nozzles must be directed toward the rear of the aircraft, at an angle between 0 and 15° downward. Do
not place nozzles on the outer 25% of the wings or rotors.
 Adjuvants and Drift Control Additives: Refer to tank mix partner's label for adjuvant directions. Drift
control additives may be used. When a drift control additive is used, read and carefully observe the
cautionary statements and all other information appearing on the additive label.

APPLICATION WITH DRY BULK FERTILIZERS

Dry bulk fertilizer may be impregnated or coated with BL3. Application of dry bulk fertilizer with BL3
provides weed control equal to, or slightly below, the same rate of BL3 applied in liquid carriers, due to
better coverage with application via spray equipment. Follow label directions for BL3 regarding rates,
special instructions, cautions and special precautions. Apply 400 to 700 pounds of the fertilizer/herbicide
mixture per acre to obtain adequate soil coverage. Apply the mixture to the soil with properly calibrated
equipment immediately after blending. Uniform application of the herbicide/fertilizer mixture is essential to
prevent possible crop injury and to obtain uniform weed control.

Do not use ammonium nitrate and/or limestone as the sole source of fertilizer, as the BL3 may not adhere
to these materials.

Compliance with all Federal and State regulations relating to blending pesticide mixtures with dry bulk
fertilizer, registrations, labeling and application are the responsibility of the individual and/or company
offering the fertilizer and BL3 mixture for sale.

BL3 must be premixed with water to form a slurry prior to impregnation on dry bulk fertilizer. For best
results, use a minimum of 1 pint of water for each 2 ounces of BL3. Use a minimum of 6 pints of the BL3
slurry to impregnate 2000 lbs. of the fertilizer for uniform coverage of the fertilizer. Closed drum, belt,
ribbon or other commonly used dry bulk blenders may be used.

The amount of BL3 required can be calculated with the following formula:

ounces of BL3 per ton
= ounces of BL3 per X 2000 ÷ pounds of fertilizer
of fertilizer acre per acre

Thoroughly clean dry fertilizer blending equipment after BL3 has been placed in the system to avoid injury
to sensitive crops that may be treated with fertilizers blended after the equipment has been used for BL3.
Rinse the sides of the blender and the herbicide tank with water. Then impregnate the rinsate onto a load
of dry fertilizer intended for an approved crop. Use a maximum rate of 1 gal. of rinsate per ton of fertilizer.
Follow with 1 to 2 loads of unimpregnated fertilizer in the blender before switching herbicides.

ROTATIONAL RESTRICTIONS

The following rotational crops may be planted after applying BL3 at the listed rate. Planting earlier than
the recommended rotational interval may result in crop injury.

 Do not plant any crop, except corn (field), cotton, peanut, soybean, sugarcane and sweet
potato earlier than 30 days after applying BL3.

SPRING BURNDOWN PROGRAMS

BL3 can be used in combination with labeled preplant burndown herbicides to assist in the
postemergence burndown of emerged weeds and provide residual weed control prior to crop emergence.

No-till planters that incorporate the soil during planting may result in decreased weed control in the row.
Apply BL3 after planting soybeans when these types of planters are used (within 3 days after planting
soybeans and before the crop emerges). BL3 cannot be applied after planting field corn.

DuPont™ BL3 can be used at 1 to 3 oz/acre with labeled preplant burndown herbicides to enhance the
speed of burndown and increase weed spectrum.

BL3 can be used in field corn and soybean burndown programs. See "DIRECTIONS FOR USE IN FIELD
CORN", "DIRECTIONS FOR USE IN SOYBEAN" for more information.

DIRECTIONS FOR USE IN FALLOW LAND

BL3 may be used as a preemergence fallow treatment.

BL3 at 2 to 3 oz/acre can be used in the fall to provide residual weed control in fallow fields (refer to
Rotational Restrictions table for rates and rotational intervals prior to planting). If weeds have emerged at
the time of application, use BL3 in combination with a labeled fallow herbicide. Application must be made
when soil temperature falls below 50°F at a 2 inch depth to maintain residual weed control into the spring.
Abnormally warm or wet winters will reduce the length of weed control observed in the spring.

BL3 at 1 to 2 oz/acre can be used in spring in combination with labeled burndown herbicides to control
emerged weeds and provide residual weed control.

DIRECTIONS FOR USE IN FIELD CORN
RESTRICTIONS AND LIMITATIONS

 Use only on no-till or minimum tillage fields where last year's crop residue has not been incorporated
into the soil.
 Corn must be planted between 14 and 30 days afte r application unless the application is made as
part of a fall burndown program.
 Corn can be planted 7 days after an application of 2 oz/acre if a minimum of 25% of the soil surface is
covered with the residue of the preceding crop and a minimum of 1/4 inch of rainfall has occurred
between application and planting.

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 18

 Do not apply more than 3 ounces of BL3 per acre during a single growing season.
 Do not irrigate between emergence and 2-leaf corn.
 Do not use on popcorn, sweet corn or corn grown for seed.
 Graze treated fields or feed treated forage to livestock no sooner than 21 days after application.

TIMING TO FIELD CORN

 Apply BL3 herbicide, at 2 to 3 oz/acre, between 7 and 30 days prior to planting field corn for the
broadleaf weeds controlled by residual activity.
 Apply BL3 herbicide at 2 oz/acre between 7 and 30 days prior to planting field corn if a minimum of
25% of the soil surface is covered with the residue of the preceding crop and a minimum of 1/4 inch
of rainfall has occurred between application and planting.

Burndown Use Directions — For Preplant Applications in Field Corn

BL3 herbicide, applied as part of a burndown program, may be used for residual weed control, as well as
to assist in postemergence burndown of many weeds where field corn will be planted directly into the
residue of the previous year. See "DIRECTIONS FOR USE IN FALL AND SPRING PREPLANT
BURNDOWN AND FALLOW SEEDBED PROGRAMS IN 1,1ELD CORN AND SOYBEAN" for rates and
timing of applications. For control of emerged weeds, BL3 herbicide must be applied with an appropriate
burndown tank mix partner. To ensure thorough coverage, use a minimum of 15 gallons of spray solution
per acre. Refer to tank mix partner's label for specified application pressure and adjuvant systems.

INCREASING SPEED OF GLYPHOSATE BURNDOWN ACTIVITY

BL3 herbicide at 1 oz/acre, may be tank mixed with glyphosate (such as Abundit® Edge) to increase the
speed of burndown activity compared to glyphosate applied alone. Residual weed control will not be
provided at rates lower than 2 oz/acre; however, suppression of the weeds may occur at BL3 herbicide
rates as low as 1 oz/acre. Applications of BL3 herbicide at 1 oz/acre must be made a minimum of 14 days
prior to planting field corn.

TANK MIXES

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

not apply when soybeans have begun to crack.

TIMING TO WEEDS

Burndown — Preemergence to Soybeans, Postemergence to Weeds

BL3, applied as part of a burndown program, may be used for residual weed control, as well as to assist
in postemergence burndown of many annual and perennial weeds where soybeans will be planted
directly into a stale seedbed, cover crop or in previous crop residues. For control of emerged weeds,
choose the most appropriate tank mix partner. Apply BL3 with ground equipment before planting, during
planting or within 3 days after planting, but before the crop emerges. To ensure thorough coverage, use a
minimum of 15 gals. of spray solution per acre. Refer to tank mix partner's label for specified application
pressure. All BL3 tank mixes applied to assist in the control of emerged weeds must be applied with crop
oil concentrate or methylated seed oil at 1 to 2 pt/acre or a non-ionic surfactant at 0.25% v/v.

INCREASING SPEED OF GLYPHOSATE BURNDOWN ACTIVITY

BL3 at rates as low as 1 oz/acre, may be tank mixed with glyphosate (ABUNDIT® Edge) to increase the
speed of burndown activity compared to glyphosate applied alone. Residual weed control will not be
provided at rates lower than 2 oz/acre; however, suppression of the weeds may occur at BL3 rates as low
as 1 oz/acre.

TANK MIXES

BL3 may be tank mixed with soybean herbicides for increased burndown activity, additional residual
broadleaf and/or additional grass control. Refer to tank mix partner's label for adjuvant directions.

flufenacet ("Axiom" or "Domain"), metolachlor (CINCHCinch®, "Dual" products or "Boundary"),
dimethenamid ("Frontier" or "Outlook") or alachlor ("Micro-Tech"), may result in severe injury to soybeans
when application is followed by prolonged periods of cool wet weather. Do not use with BL3, unless
Supplemental or Special Local Need Labeling, provided by DuPontCorteva Agriscience, is followed.

SPRAY DRIFT MANAGEMENT

The interaction of many equipment and weather-related factors determines the potential for spray drift.
The applicator is responsible for considering all these factors when making application decisions.

Avoiding spray drift is the responsibility of the applicator.

IMPORTANCE OF DROPLET SIZE

The most effective drift management strategy is to apply the largest droplets which are consistent with
pest control objectives. The presence of sensitive species nearby, the environmental conditions, and pest
pressure may affect how an applicator balances drift control and coverage. Applying larger droplets
reduces drift potential, but will not prevent drift if applications are made improperly or under unfavorable
environmental conditions.

A droplet size classification system describes the range of droplet sizes produced by spray nozzles. The
American Society of Agricultural and Biological Engineers (ASABE) provide a Standard that describes
droplet size spectrum categories defined by a number of reference nozzles (fine, coarse, etc.). Droplet
spectra resulting from the use of a specific nozzle may also be described in terms of volume mean
diameter (VMD). Coarser droplet size spectra have larger VMD' s and lower drift potential.

Controlling Droplet Size - Ground Application

 Nozzle Type - Select a nozzle type that is designed for the intended application. With most nozzle
types, narrower spray angles produce larger droplets. The use of low-drift nozzles will reduce drift
potential.
 Pressure - The lowest spray pressures recommended for the nozzle produce the largest droplets.
Higher pressure reduces droplet size and does not improve canopy penetration. When higher flow
rates are needed, using a higher-capacity nozzle instead of increasing pressure results in the
coarsest droplet spectrum.
 Flow Rate/Orifice Size - Using the highest flow rate nozzles (largest orifice) that are consistent with
pest control objectives reduces the potential for spray drift. Nozzles with higher rated flows produce
coarser droplet spectra.

Controlling Droplet Size – Aircraft

 Nozzle Type - Solid stream, or other low drift nozzles produce the coarsest droplet spectra.
 Number of Nozzles - Using the minimum number of nozzles with the highest flow rate that provide
uniform coverage will produce a coarser droplet spectrum.
 Nozzle Orientation - Orienting nozzles in a manner that minimizes the effects of air shear will
produce the coarsest droplet spectra. For some nozzles such as solid stream, pointing the nozzles
straight back parallel to the airstream will produce a coarser droplet spectrum than other orientations.
 Pressure — Selecting the pressure that produces the coarsest droplet spectrum for a particular
nozzle and airspeed reduces spray drift potential. For some nozzle types such as solid streams, lower
pressures can produce finer droplet spectra and increase drift potential.

BOOM LENGTH (AIRCRAFT), AND APPLICATION HEIGHT

Boom Length (aircraft) - Using shorter booms decreases drift potential. Boom lengths are expressed as

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 21

a percentage of an aircraft's wingspan or a helicopter's rotor blade diameter. Shorter boom length and
proper positioning can minimize drift caused by wingtip or rotor vortices.

Application Height (aircraft) - Applications made at the lowest height that are consistent with pest
control objectives and the safe operation of the aircraft will reduce the potential for spray drift.

Application Height (ground) - Applications made at the lowest height consistent with pest control
objectives, and that allow the applicator to keep the boom level with the application site and minimize
bounce, will reduce the exposure of spray droplets to evaporation and wind, and reduce spray drift
potential.

WIND

Drift potential is lowest when applications are made in light to gentle sustained winds (2-10 mph), which
are blowing in a constant direction. Many factors, including droplet size and equipment type determine
drift potential at any given wind speed. AVOID GUSTY OR WINDLESS CONDMONS.

Local terrain can also influence wind patterns. Every applicator is expected to be familiar with local wind
patterns and how they affect spray drift.

TEMPERATURE AND HUMIDITY

When making applications in hot and dry conditions, set up equipment to produce larger droplets to
reduce effects of evaporation.

SURFACE TEMPERATURE INVERSIONS

Drift potential is high during a surface temperature inversion. Surface temperature inversions restrict
vertical air mixing, which may cause small suspended droplets to remain close to the ground and move
laterally in a concentrated cloud. Surface temperature inversions are characterized by increasing
temperature with altitude and are common on nights with limited cloud cover and light to no wind. They
begin to form as the sun sets and often continue into the morning Mist or fog may indicate the presence
of an inversion in humid areas.

Inversions may also be identified by producing smoke and observing its behavior. Smoke that remains
close to the ground, or moves laterally in a concentrated cloud under low wind conditions indicates a
surface inversion. Smoke that moves upward and rapidly dissipates indicates good vertical air mixing.

SENSITIVE AREAS

Making applications when there is a sustained wind moving away from adjacent sensitive areas (e.g.,
residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops)
is an effective way to minimize the effect of 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
Council of Producers & Distributors of Agrotechnology (CPDA).

SHIELDED SPRAYERS

Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility
of the applicator to verify that the shields are preventing drift and not interfering with uniform deposition of

M6D / BL3 / MSTR / Notification with edits / 06-30-22 Page 22

the product.

AIR ASSISTED (AIR BLAST) FIELD CROP SPRAYERS

Air assisted field crop sprayers carry droplets to the target via a downward directed air stream. Some may
reduce the potential for drift, but if a sprayer is unsuitable for the application and/or set up improperly,
high drift potential can result. It is the responsibility of the applicator to determine that a sprayer is suitable
for the intended application, is configured properly, and that drift is not occurring.
