PRODUCT INFORMATION

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 program 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 that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

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.

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 9

• 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 yards of non-dormant pears. • 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 surface water is present or to intertidal areas below the mean high water mark. Drift or runoff may be hazardous to non-target plants and aquatic organisms in neighboring areas. • DO NOT apply where runoff is likely to occur. • DO NOT 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 application or residual weed control will be reduced. • DO NOT apply 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 clean water away from the well site. • Mix only enough product for the job at hand and avoid overfilling of spray tank. • When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix. • Thoroughly clean BL3 from application equipment immediately 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, insecticides, fungicides and seeds during storage. • Spray equipment used to apply BL3 should not be used to apply other materials to any crop foliage, unless the proper cleanout procedures are followed. See "SPRAYER CLEANUP" for more information.

WEED RESISTANCE MANAGEMENT

For resistance management, BL3 is a Group 14 herbicide. Any weed population may contain or develop plants naturally resistant to BL3 and other Group 14 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance management strategies should be followed.

Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or more herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides with different modes of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices. Research has demonstrated that using the labeled rate and directions for use is important to delay the selection for resistance.

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 10

The continued effectiveness of this product depends on the successful implementation of a weed resistance management program.

To aid in the prevention of developing weeds resistant to this product, users should: • Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes present. • Start with a clean field, using either a burndown herbicide application or tillage. • If using post-emergence herbicides or tank mixes, control weeds early when they are relatively small. • Apply full rates of this product for the most difficult to control weed in the field at the specified time to minimize weed escapes. • Scout fields after application to detect weed es capes or shifts in control of weed species. • Control weed escapes before they reproduce by seed or proliferate vegetatively. • Report any incidence of non-performance of this product against a particular weed to your local company representative, local retailer, or county extension agent. • Contact your local company representative, crop advisor, or extension agent to find out if suspected resistant weeds to these MOAs have been found in your region. DO NOT assume that each listed weed is being controlled by multiple mode of action. Products with multiple active ingredients are intended to broaden the spectrum of weeds that are controlled. Some weeds may be controlled by only one of the active ingredients in this product. • If resistance is suspected, treat weed escapes with an herbicide having a mode of action other than Group 14 and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production. • Suspected herbicide-resistant weeds may be identified by these indicators: Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds. A spreading patch of non-controlled plants of a particular weed species; and Surviving plants mixed with controlled individuals of the same species.

Additionally, users should follow as many of the following herbicide resistance management practices as is practical: • Use a broad spectrum herbicide with other mode of action as a foundation in a weed control program, if appropriate. • Utilize sequential applications of herbicides with alternative modes of action. • Rotate the use of this product with non-Group 14 herbicides. • Avoid making more than two sequential applications of this product and any other Group 14 herbicides within a single growing season unless mixed with an herbicide with a different mode of action with an overlapping spectrum for the difficult-to-control weeds. • Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops and weed-free crop seeds, as part of an integrated weed control program. • Use good agronomic principles that enhance crop development and crop competitiveness. • Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. • Manage weeds in and around fields to reduce weed seed production.

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 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

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 11

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.

MANDATORY SPRAY DRIFT MANAGEMENT Aerial Applications: • DO NOT release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater application height is necessary for pilot safety. • Applicators must select nozzle and pressure that deliver Medium or coarser droplets in accordance with American Society of Agricultural & Biological Engineers Standard 641 (ASABE S641).

• If the windspeed is 10 miles per hour or less, applicators must use ½ swath displacement upwind at the downwind edge of the field. When the windspeed is between 11-15 miles per hour, applicators must use ¾ swath displacement upwind at the downwind edge of the field.

• DO NOT apply when wind speeds exceed 15 mph at the application site. If the windspeed is greater than 10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 75% or less of the rotor diameter for helicopters. Othe1wise, the boom length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or less of the rotor diameter for helicopters

• DO NOT apply during temperature inversions.

Ground Boom Applications: • User must only apply with the release height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy. • Applicators must select nozzle and pressure that deliver Medium or coarser droplets in accordance with American Society of Agricultural & Biological Engineers Standard 572 (ASABE S572). • DO NOT apply when wind speeds exceed 15 miles per hour at the application site. • DO NOT apply during temperature inversions.

Boomless Ground Applications: • Applicators must select nozzle and pressure that deliver Medium or coarser droplets in accordance with American Society of Agricultural & Biological Engineers Standard 572 (ASABE S572).

• DO NOT apply when wind speeds exceed 15 miles per hour at the application site. • DO NOT apply during temperature inversions.

SPRAY DRIFT ADVISORIES

THE APPLICATOR IS RESPONSIBLE FOR A VOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.

IMPORTANCE OF DROPLET SIZE

An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable environment.al conditions.

Controlling Droplet Size - Ground Boom

• Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate. • Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. • Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift.

Controlling Droplet Size – Aircraft

• Adjust Nozzles - Follow nozzle manufacturers' recommendations for setting up nozzles. Generally, to reduce fine droplets, nozzles should be oriented parallel with the airflow in flight.

BOOM HEIGHT - Ground Boom For ground equipment, the boom should remain level with the crop and have minimal bounce.

RELEASE HEIGHT - Aircraft Higher release heights increase the potential for spray drift.

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.

BOOMLESS GROUND APPLICATIONS: Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.

HANDHELD TECHNOLOGY APPLICATIONS: Take precautions to minimize spray drift.

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.

TEMPERATURE AND HUMIDITY When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.

TEMPERATURE INVERSIONS Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Avoid applications during temperature inversions.

WIND Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.

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.

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 13

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).

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

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 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, 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 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 including cutleaf evening primrose 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, including 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.

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.
Add 1 gram of BL3 to the quart jar for every 3 ounces of BL3 per acre being applied, gently mix until product goes into suspension.
Add 60 milliliters (4 Tbsp or 2 fl oz) of the crop oil 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.
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.
Place cap on jar, invert 10 times, let stand for 15 minutes, evaluate.
An ideal tank mix combination will be uniform and 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 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.

Thoroughly rinse sprayer, tanks, boom, and hoses with clean water.
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

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 15

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

Fill clean spray tank 1/2 to 2/3 of desired level with clean water.
If a drift retardant is to be used, add 10 lbs of spray grade ammonium sulfate per 100 gals. of spray solution.
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.
While agitating, slowly add the pre-slurried BL3 to the spray tank. Agitation should create a rippling or rolling action on the water surface.
If tank mixing BL3 with other labeled herbicides, 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.
Add any required adjuvants.
Fill spray tank to desired level with water. Continue agitation until all spray solution has been applied.
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:

Drain the tank and thoroughly hose down the interior surfaces. Flush tank, boom, and hoses with clean water for a minimum of 5 minutes.
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.
Remove the nozzles, screens and the end caps of sprayer booms and clean separately in a bucket containing water and the cleaning agent.
Repeat Step 2.
Thoroughly rinse the tank with clean water for a minimum of 5 minutes, flushing water through the boom and hoses.
To enhance removal of flumioxazin from the spray 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 minutes. If using "Valent Tank Cleaner" follow use instructions and personal protective equipment (PPE) instructions as found on the "Valent Tank Cleaner" label.

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 16

*Equivalent amounts of an alternate strength ammonia solution or a tank cleaner recommended in separately published 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 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, including 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,

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 17

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.

Use Programs 2 or 3 to control cutleaf evening primrose that are 12 inches or less and in the rosette stage.

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.

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 after 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. 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.

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 22

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 (including 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 tank mixing Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

BL3 herbicide may be tank mixed with other herbicides for pre-plant burndown applications. Refer to tank mix partner's label for adjuvant directions.

Tank mix partners for burndown and/or residual control of weeds in field corn are 2,4-D, atrazine, rimsulfuron + thifensulfuron-methyl, dicamba, glyphosate, metribuzin, paraquat, Liberty brand herbicide products, thifensulfuron-methyl + tribenuron-methyl and simazine. Refer to tank mix product labels for specific recommendations.

TANK MIX RESTRICTIONS

Tank mixes with flufenacet, metolachlor or s-metolachlor, dimethenamid or dimethenamid-p, alachlor, or acetochlor may result in injury to field corn when application is followed by prolonged periods of cool wet weather. DO NOT use with BL3 herbicide, unless Supplemental or Special Local Need Labeling, provided by Corteva Agriscience.

DIRECTIONS FOR USE IN SOYBEAN RESTRICTIONS AND LIMITATIONS

DO NOT apply more than 3 ounces of BL3 herbicide per acre during a single growing season. DO NOT tank mix BL3 herbicide with acetochlor), alachlor, flufenacet, metolachlor or dimethenamid within 14 days of planting soybeans, unless soybeans are planted under no-till or minimum tillage conditions on wheat stubble or no-till field corn stubble. DO NOT irrigate when soybeans are cracking. DO NOT graze treated fields or feed treated hay to livestock sooner than 21 days after application.

M6D / BL3 / MSTR / IRRD Amend / 06-06-2026 Page 23

TIMING TO SOYBEANS

BL3 may be applied to soybeans prior to planting or preemergence (after planting). Preemergence application of BL3 must be made within 3 days after planting and prior to soybean emergence. Application after the soybeans have begun to crack, or are emerged, will result in severe crop injury. DO 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 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. Refer to tank mix product labels for specific directions for control of emerged weeds present.

ADDITIONAL RESIDUAL BROADLEAF CONTROL

BL3 can be tank mixed with metribuzin, chlorimuron, chlorimuron + metribuzin, tribenuron-methyl, or cloransulam-methyl for additional broadleaf control.

ADDITIONAL RESIDUAL GRASS CONTROL

BL3 can be tank mixed with pendimethalin for additional grass control. Tank mixes with flufenacet, metolachlor, dimethenamid or alachlor, 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 Corteva Agriscience.
