ENVIRONMENTAL HAZARDS
F9387-1 HERBICIDE (referred to below as F9387-1) is very toxic to algae and moderately toxic to fish. DO NOT apply
directly to water, to areas where surface water is present or to intertidal areas below the high water mark. DO NOT
contaminate water when disposing of equipment wash waters or rinsate.
Groundwater Advisory
This chemical and its degradation products have properties and characteristics associated with chemicals detected
in ground water. This chemical may leach into ground water if used in areas where soils are permeable, particularly
where the water table is shallow.
Surface Water Advisory
This product may impact surface water quality due to spray drift and runoff of rain water. This is especially true for
poorly draining soils and soils with shallow ground water. This product is classified as having high potential for reaching
surface water via runoff for several months after application. A level, well-maintained vegetative buffer strip between
areas to which this product is applied and surface water features including ponds, streams, and springs will reduce
the potential loading of F9387-1 from runoff water and sediment. Runoff of this product will be reduced by avoiding
applications when rainfall is forecasted to occur within 48 hours.
Non-target Organism Advisory
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms., including
pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non-target organisms by minimizing
spray drift.
Physical/Chemical Hazards
DO NOT use or store near heat or open flame.
MIXING AND LOADING INSTRUCTIONS
This product must not be mixed or loaded within 50 feet of any wells (including abandoned wells and drainage wells),
sink holes, perennial or intermittent streams and rivers, and natural or impounded lakes and reservoirs. This setback
does not apply to properly capped or plugged abandoned wells and does not apply to impervious pad or properly diked
mixing/loading areas.
Operations that involve mixing, loading rinsing, or washing of this product into or from pesticide handling or application
equipment or containers within 50 feet of any well are prohibited unless conducted on an impervious pad constructed to
withstand the weight of the heaviest load that may be positioned on or moved across the pad. Such a pad shall be
designed and maintained to contain any product spills or equipment leaks, container or equipment rinse or wash water,
and rainwater that may fall on the pad. Surface water shall not be allowed to either flow over or from the pad, which
means the pad must be self contained. The pad shall be sloped to facilitate material removal. An unroofed pad shall be
of sufficient capacity to contain at a minimum 110% of the capacity of the largest pesticide container or application
equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude precipitation from contact
with the pad shall have a minimum containment capacity of 100% of the capacity of the largest pesticide container or
application equipment on the pad. Containment capacities as described above shall be maintained at all times. The
above specific minimum containment capacities DO NOT apply to vehicles when delivering pesticide shipments to the
mixing/loading site. States may have in effect additional requirements regarding wellhead setbacks and operational
containment.
This product must be used in a manner which will prevent back siphoning into wells, spills or improper disposal of
excess pesticide, spray mixtures or rinsates.
1. The spray equipment must be clean before using this product. If it is contaminated with other materials, mixing
problems and/or clogging may occur or crop injury may occur.
2. Prepare no more spray mixture than is needed for the immediate application, and DO NOT let the spray
mixture stand in the spray tank overnight.
3. Maintain maximum agitation throughout the spraying operation.
4. Flush the spray equipment thoroughly after each use and apply rinsate to an appropriate area.

PRODUCT INFORMATION
F9387-1 herbicide contains two active ingredients possessing both contact and systemic activity that can be applied
Post emergence for selective control of broadleaf weeds in field corn, seed corn, yellow pop-corn, sweet corn. DO NOT
apply to White Popcorn or ornamental (Indian) corn. When applied as POST application it may take 2 to 15 days to kill
the weeds on the list. The product is absorbed through the soil and /or by the weed foliage.
For effective control of grasses, F9387-1 can be tank mixed with other POST grass herbicides to provide broader
spectrum weed control in corn. F9387-1 application can also be combined with a burndown herbicide, prior to planting,
to provide added burndown and residual weed control in field corn, seed corn, yellow popcorn, and sweet corn.
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 direction 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.
WEED RESITANCE MANAGEMENT
F9387-1 contains both a Group 14 (fluthiacet-methyl) and a Group 27 (mesotrione) herbicide based on the mode of
action classification system of the Weed Science Society of America.
Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one
or more herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides
with different sites of action and overlapping weed spectrum with or without tillage operations and/or other cultural
practices.
Research has demonstrated that using the labeled rate and directions for use is important to delay the selection for
resistance.
The continued effectiveness of this product depends on the successful implementation of a weed resistance
management program.
To aid in the prevention of developing weeds resistant to this product, users should:
• Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed
sizes present
• Start with a clean field, using either a burndown herbicide application or tillage.
• Control weeds early when they are relatively small (less than 4 inches).
• Apply full rates of F9387-1 for the most difficult to control weed in the field at the specified time (correct weed size)
to minimize weed escapes.
• Scout fields after application to detect weed escapes or shifts in control of weed species.
• Control weed escapes before they reproduce by seed or proliferate vegetatively.
• Report any incidence of non-performance of this product against a particular weed to your FMC representative,
local retailer, or county extension agent.
• Contact your FMC representative, crop advisor, or extension agent to find out if suspected resistant weeds to this
MOA have been found in your region. If resistant biotypes of target weeds have been reported, use the application
rates of this product specified for your local conditions. Tank mix products so that there are multiple effective sites
of actions for each target weed.
• If resistance is suspected, treat weed escapes with an herbicide having a site of action other than Group 14 and
Group 27 and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing further
seed production.
• Suspected herbicide-resistant weeds may be identified by these indicators:
• Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if
control is achieved on adjacent weeds;
• A spreading patch of non-controlled plants of a particular weed species; and
• Surviving plants mixed with controlled individuals of the same species.
Additionally, users should follow as many of the following herbicide resistance management practices as is practical:
• Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program.
• Utilize sequential applications of herbicides with alternative sites of action.
• Rotate the use of this product with non-Group 14/Group 27 herbicides.
• Incorporate non-chemical weed control practices, including mechanical cultivation, crop rotation, cover crops and
weed-free crop seeds, as part of an integrated weed control program.
• Use good agronomic principles that enhance crop development and crop competitiveness.
• Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds.
• Manage weeds in and around fields, during and after harvest to reduce weed seed production.
DIRECTIONS FOR USE
Misuse Statement
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS LABEL MAY RESULT IN POOR
WEED CONTROL, CROP INJURY, OR ILLEGAL RESIDUES.
Utilize a sprayer equipped with the appropriate nozzles providing optimum spray distribution and coverage at the
appropriate operating pressures. Utilize nozzles that produce minimal amounts of fine spray droplets to avoid spray drift.
Apply a minimum of 10 gallons of finished spray solution per acre by ground. If a dense crop and or weed canopy is
present use a minimum of 15 gallons per acre of finished spray volume by ground application. For best results apply
F9387-1 with medium spray droplets. The sprayer must be properly calibrated to deliver the appropriate volume of
herbicide solution. Be aware that overlaps and slower ground speeds while starting, stopping or turning while spraying
may result in excessive application and subsequent crop response. Mix the amount which will be used for spraying on
that day.
Restrictions
• DO NOT exceed 3.15 fl oz of F9387-1 /A (0.0053 lb ai/A fluthiacet-methyl + 0.0931 lb ai/A mesotrione) in a single
postemergence application.
• DO NOT apply more than a total of 5.25 fl oz of F9387-1/A (0.0089 lb ai/A fluthiacet-methyl + 0.155 lb ai/A
mesotrione) per year including preplant burndown and labeled postemergence applications to corn.
• DO NOT exceed 2 applications of F9387-1 per year.
• DO NOT apply more than 0.0089 lb ai/A of fluthiacet-methyl or 0.24 lb ai/A of mesotrione per year including all
preplant or postemergence herbicides containing these active ingredients.
• DO NOT make the second application of F9387-1 within 14 days of the first application.
• DO NOT harvest or feed forage within 45 days after application.
• DO NOT harvest or feed grain or stover (fodder) within 70 days after application.
• DO NOT harvest or feed sweet corn forage or ears within 40 days after application.
• DO NOT include nitrogen based adjuvants (UAN or AMS) when making postemergence applications of F9387-1
to yellow popcorn or sweet corn.
• DO NOT apply F9387-1 to white popcorn or ornamental (Indian) corn.
• DO NOT apply to corn that is more than 12 inches in height if atrazine is mixed with F9387-1
• DO NOT apply this product through any type of irrigation system.
• DO NOT use aerial application to apply F9387-1.
• DO NOT harvest or feed field corn forage until 30 days after the last application.
• DO NOT apply this product with suspension fertilizers as the carrier.
• DO NOT apply product postemergence in a tank mix with emulsifiable concentrate grass herbicides, unless
specifically addressed under one of the tank mix sections of this label, or injury may occur.
Precautions
1. Avoid drift onto adjacent crops.
2. Severe corn injury may occur if F9387-1 is applied postemergence to corn that was treated with Counter® (EPA
Reg. No. 5481-562, Terbufos) or Lorsban® (Lorsban® 15G Granular Insecticide (62719-34), Lorsban 50W in
Water Soluble Packets Insecticide (62719-221), Lorsban® Advanced Insecticide (62719-591), Lorsban®-4E
insecticide (62719-220), Chlorpyrifos) in-furrow at planting, which may result in corn crop yield loss.
3. Severe corn injury may occur if F9387-1 is applied foliar postemergence in a tank mix with any organophosphate
or carbamate insecticide which may result in corn crop yield loss.
4. Severe corn injury may occur if any organophosphate or carbamate insecticide is applied foliar postemergence
within 7 days before or 7 days after F9387-1 application, which may result in corn crop yield loss.
5. DO NOT cultivate corn within 7 days before or after a F9387-1 application as weed control from the F9387-1
application may be reduced.
Rainfastness
F9387-1 requires a minimum of 1 hour rain-free period after application for best results when applied postemergence.
Cultivation
DO NOT cultivate immediately prior to post-emergence application. Cultivation may put weeds under stress, reducing
weed control. Timely cultivation 1-3 weeks after applying F9387-1 may assist weed control.
POSTEMERGENCE GROUND APPLICATION
Spray nozzles must be uniformly spaced, the same size and type, and must provide accurate and uniform application.
Use spray nozzles that provide medium to coarse droplet size to provide good coverage and avoid drift. Good coverage
of foliage is essential for optimum weed control. Boom height for broadcast over-the-top applications must be based on
the height of the crop - at least 18 inches above the crop canopy.
Apply in a spray volume of 10-30 gals./A. Use a pump that can maintain a pressure of at least 35-40 psi at the nozzles
and provide proper agitation within the tank to keep the product dispersed. Lower pressures may be used with extended
range or drift reduction nozzles. When weed foliage is dense, use a minimum of 15 gals.
Flat fan nozzles of 80° or 110° are advised for optimum postemergence coverage.
DO NOT use floodjet nozzles, extremely coarse droplet nozzles, or controlled droplet application equipment for
postemergence applications.
Nozzles may be angled forward 45° to enhance penetration of the crop and provide better coverage. Ensure that all in-
line strainer and nozzle screens in the sprayer are 50-mesh or coarser.
Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time. If the
agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying.
Adjuvant Requirements
An adjuvant or a product containing an adjuvant is required with F9387-1 for maximum consistent performance. Only
spray additives cleared for use on growing crops under 40 CFR 180.1001 may be used in spray mixture.
Postemergence Applications to Field Corn and Seed Corn
Add crop oil concentrate (COC) to the Postemergence application at the rate of 0.5 to 1.0 gal./100 gals. of water (0.5%
to 1.0% v/v). The use of a nonionic surfactant (NIS) at 1 qt./100 gallons of water (0.25% v/v) instead of COC is allowed,
but the weed control achieved with COC is consistently better than NIS. The use of methylated seed oil (MSO) adjuvants
or MSO blend adjuvants for postemergence applications of F9387-1 may cause severe crop injury. In addition to COC,
always add spray grade UAN (e.g., 28-0-0) to the spray solution at a rate of 2.5% (v/v) or AMS at 8.5 lb./100 gals. of
spray solution, except if precluded elsewhere on this label. If F9387-1 is being tank mixed with another registered
herbicide in this situation, refer to the tank mix partner label for adjuvant precautions and restrictions and follow the most
restrictive requirements.
DO NOT use liquid fertilizer as the total carrier solution except for preplant burndown applications.
Postemergence Applications to Sweet Corn and Yellow Popcorn
DO NOT add UAN or AMS when making postemergence applications of F9387-1 to yellow popcorn or sweet
corn, or severe crop injury may occur.
For postemergence applications to yellow popcorn and sweet corn , use nonionic surfactant (NIS) at 1 qt./100
gallons of water (0.25% v/v) to minimize the risk of crop injury. A COC may be used, and will increase the level of weed
control achieved, especially under dry growing conditions, but the risk of crop injury is increased. For optimum control,
the addition of atrazine is advised wherever rotational or local atrazine restrictions allow.
Mixing F9387-1 Alone
1. Add 1/4-1/2 of the required amount of clean water to the spray or mixing tank.
2. With the agitator running, add the required amount of F9387-1 to the spray tank. Continue agitation in the spray
tank and allow product to fully and uniformly disperse.
3. Add the spray adjuvant and continue agitation while adding the rest of the water.
4. Maintain agitation until all of the mixture has been applied.
Mixing F9387-1 in Tank Mixtures with Other Pesticides
F9387-1 is compatible with most commonly used herbicides, insecticides, fungicides, and spray adjuvants. Follow WALE
(Wettable/dry, Agitate, Liquids, and Emulsifiable Concentrates) mixing guidelines. It is the pesticide users 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. If the instructions on the tank mix partner label
conflicts with this F9387-1 label, DO NOT use in a tank mixture with F9387-1.
Tank Mixing Steps
1. Add 1/4 -1/2 of the required amount of clean water to the spray or mixing tank.
2. While maintaining agitation, continue filling the spray tank. When the tank is 3/4 full, add any dry formulation tank
mix partners and allow them to completely and uniformly disperse.
3. Add the required amount of F9387-1 to the spray tank while maintaining agitation. After the product has completely
and uniformly dispersed into the tank mix, add any other liquid tank mix partners and allow them to completely
and uniformly disperse.
4. Add the proper amount of spray adjuvant and continue agitation while adding the remaining water.
5. Complete filling the tank with clean water and maintain sufficient agitation at all times to insure surface action until
the mixture is uniform.
6. After use, thoroughly clean the sprayer according to this label (see Cleaning Spray Equipment) and any tank mix
partner labels.
Compatibility Test
A jar test is advised before mixing to ensure F9387-1 compatibility with tank mix partners and adjuvants. The following
test assumes a spray volume of 25 gallons per acre. For other spray volumes, make appropriate changes in the
ingredient rates.
1. Add 1.0 pt. of water to each of 2 one-quart jars.
Note: Use the same source of water and the other components in the compatibility test that will actually be tank
mixed and applied. It is important that all components are mixed at a temperature similar to the temperature of
those used for the actual application.
2. To one of the jars, add 1/4 tsp. or 1.2 milliliters of a compatibility agent approved for this use (1/4 tsp. is equivalent
to 2 pt/100 gallons spray). Shake or stir gently to mix.
3. To both jars, add the appropriate amount of herbicide(s). If more than one herbicide is used, add them separately
with dry herbicides first, flowables next, and emulsifiable concentrates last. Finally, add the appropriate amount
of any adjuvants that will be used. After each addition, shake or stir gently to thoroughly mix. The appropriate
amount of herbicides for this test follows:
Dry Herbicides and Adjuvants: For each pound to be applied per acre, add 1.4 tsp. to each jar.
Liquid Herbicides and Adjuvants: For each pint to be applied per acre, add 0.5 tsp. or 2.5 milliliters to each jar.
4. After adding all ingredients, put lids on and tighten, and invert each jar 10 times to mix. Let the mixtures stand 15-
30 minutes and look for separation, large flakes, precipitates, gels, heavy oil film on the jar, or other signs of
incompatibility. Determine if a compatibility agent is needed in the spray mixture by comparing the two jars. If
either mixture separates, but can be remixed readily, the mixture can be sprayed as long as good agitation is
used. If the mixtures are incompatible, test the following methods of improving compatibility.
a. Slurry the dry pesticide(s) in water before addition, or
b. Add 1/2 the compatibility agent to the water and the other 1/2 to the emulsifiable concentrate or flowable
pesticide before addition to the mixture. If incompatibility is still observed, DO NOT use the mixture.
After compatibility testing is complete, dispose of any pesticide wastes according to the Storage and Disposal section
of this label.
MANDATORY SPRAY DRIFT MANAGEMENT
Ground Boom Applications:
• Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or
crop canopy.
• For applications prior to the emergence of crops and target weeds, applicators are required to use a Coarse
or coarser droplet size (ASABE S572.1).
• For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE S572.1).
• DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
• DO NOT apply during temperature inversions.
SPRAY DRIFT MANAGEMENT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT.
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest
control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are
made improperly or under unfavorable environmental conditions.
Controlling Droplet Size Ground Boom
Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest
practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher
flow rate.
Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet
size.
Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to
reduce drift.
BOOM HEIGHT Ground Boom
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. For ground
equipment, the boom must remain level with the crop and have minimal bounce.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the
shields are not interfering with the uniform deposition of the spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing
temperature with altitude and are common on nights with limited cloud cover and light to no wind. The presence of an
inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke
generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an
inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Avoid applications
during temperature inversions.
WIND
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS.
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.
HANDHELD TECHNOLOGY APPLICATIONS
Take precautions to minimize spray drift
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read
and carefully observe cautionary statements and all other information on the additives 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).
CROP ROTATION RESTRICTIONS
Immediate: Corn (field, seed, sweet corn and pop)
Following harvest of corn the following crops may be planted immediately: Asparagus, cranberry, flex,
millet(pearl), grasses grown for seed (Kentucky bluegrass, perennial ryegrass, and tall fescue), oats, rhubarb, sorghum
(grain and sweet), and sugarcane.
Following harvest of corn and not less than 4 months after application of F9387-1, the following crops may be
planted: Small grains including wheat, barley, and rye.
Following harvest of corn and not less than 10 months after application of F9387-1, the following crops may be
planted: Alfalfa, blueberry, canola, cotton, lingonberry, peanuts, potatoes, soybeans, sunflowers, tobacco, okra and rice
can be planted back the following season. If F9387-1 is applied postemergence following a mesotrione-containing
preemergence herbicide, only corn (field, seed and pop) or grain sorghum may be replanted the year following
application or severe crop injury may occur.
Following harvest of corn and not less than 18 months after application of F9387-1, the following crops may be
planted: Sugar beets, dry beans, snap beans, cucurbits, red clover, and all other rotational crops may be replanted 18
months after application of F9387-1.
REPLANTING INSTRUCTIONS
If replanting is necessary in fields previously treated with F9387-1, the field may be replanted to Corn (field, seed and
pop). If tank-mix combinations were used, refer to product labels for any additional replanting instructions.
SPRAYER EQUIPMENT CLEAN-OUT
Many pesticides are very active at low rates, especially to sensitive crops. Residues left in mixing equipment, spray
tanks, hoses, spray booms and nozzles can cause crop effects if they are not properly cleaned. As soon as possible
after spraying F9387-1 and before using the sprayer equipment for any other applications, the sprayer equipment must
be thoroughly cleaned using the following procedure. In addition, users must take appropriate steps to ensure proper
equipment clean-out for any other products mixed with F9387-1 as required on the other product labels. More complete
cleaning can be achieved if the spray system is cleaned immediately following the application.
1. Drain sprayer tank, hoses, spray boom and spray nozzles. Use a high-pressure detergent wash to remove
physical sediment and residues from the inside of the sprayer tank and thoroughly rinse. Then, thoroughly flush
sprayer hoses, spray boom and spray nozzles with a clean water rinse. Remove and clean spray tips and all
filters and screens (tank, spray hose and spray tips) separately in the ammonia solution of Step 2.
2. Next, prepare a sprayer cleaning solution by adding three gallons of ammonia (containing at least 3% active)
per 100 gallons of clean water. Prepare sufficient cleaning solution to allow the operation of the spray system
for a minimum of 15 minutes to thoroughly flush hoses, spray boom and spray nozzles.
3. Convenient and thorough cleaning of the sprayer can be achieved if the ammonia solution or fresh water is left
in the spray tank, hoses, spray booms and spray nozzles overnight or during storage.
4. Before using the sprayer, completely drain the sprayer system. Rinse the tank with clean water and flush through
the hoses, spray boom, and spray nozzles with clean water. Remove and clean spray tips and all filters and
screens (tank, spray hose and spray tip) separately in an ammonia solution.
5. Properly dispose of all cleaning solution and rinsate in accordance with Federal, State, and local regulations and
guidelines.
6. DO NOT apply sprayer cleaning solutions or rinsate to sensitive crops.
7. If the sprayer sets overnight or for any extended period of time with F9387-1 spray solution, the spray tank needs
to be agitated and purge the spray boom and nozzles before beginning any application.
8. Small quantities of F9387-1 remaining in inadequately cleaned mixing, loading and/or spray equipment, could
be released during subsequent applications potentially causing effects to certain crops and other vegetation.
FMC accepts no liability for any effects due to inadequately cleaned equipment.
9. When F9387-1 has been tank mixed refer to the label of the product used previously or tank mixed with F9387-
1 for cleaning instructions.
10. DO NOT drain or flush equipment on or near desirable trees or plants.
11. DO NOT contaminate any body of water including irrigation water that may be used on other crops.
WEEDS CONTROLLED
F9387-1 Application Alone
At the rates and weed size listed, F9387-1 controls or suppresses the weeds listed in Table 1 when the product is applied
alone. Weeds larger than the size indicated in Table 1 may only be partially controlled. For best postemergence results,
apply F9387-1 to actively growing weeds. Dry weather following application of F9387-1 may reduce residual weed control
effectiveness. F9387-1 applied alone or in mixture with atrazine will not provide consistent or effective control of weeds
identified as resistant to postemergence group 27 herbicides.

CROP USE DIRECTIONS
CORN
(Includes field corn, seed corn, sweet corn and yellow popcorn)
Timing and Method of Application:
Preplant Burndown
Apply F9387-1 Herbicide from 2 to 3.75 fl oz/A (0.0034 0.0063 lb ai/A fluthiacet-methyl + 0.0591 0.111 lb ai/A
mesotrione) with other registered burndown herbicides in water or liquid fertilizers as a burn-down treatment to control
or suppress weeds prior to planting. For improved broadleaf weed control with limited residual control prior to planting
corn and before corn emergence, apply F9387-1 in tank mixes with Aim® (EPA Reg. No. 279-3241,Carfentrazone-ethyl),
paraquat, glyphosate, glufosinate, dicamba, Sharpen ® (EPA Reg. No. 7969-278, Saflufenacil), and 2,4-D. Refer to
individual product labels for precautionary statements, restrictions, rates, approved uses, and a list of weeds controlled.
Always use the most restrictive label language when applied in a tank mix. For optimum performance make applications
to actively growing weeds.
Postemergence Application
Use Rate: Apply F9387-1 at 2.5 to 3.15 fl oz/A (0.0042 0.0053 lb ai/A fluthiacet-methyl + 0.074 0.0931 lb ai/A
mesotrione) Refer to weed table 1 for specific use rate requirements.
F9387-1 may be applied broadcast postemergence up to the V8 growth stage (or 30 inches tall). The spray boom must
be maintained at a minimum of 18 inches above the crop canopy to ensure uniform spray delivery and avoid
concentrating spray in corn whorls. For optimum performance, make application to actively growing weeds <5 inches
tall and rosettes less than 3 inches across. Application after weeds have reached the listed maximum height for control
could result in commercially unacceptable weed control. F9387-1 herbicide may be tank mixed with other herbicides
registered for use in corn to improve weed spectrum or general weed control unless restricted under the corn crop
section.
Refer to seed company requirements for use on field corn inbred lines. Special adjuvant restrictions must be followed
for postemergence applications of F9387-1 in yellow popcorn or sweet corn (see the spray adjuvant recommendation in
the Directions For Use Section).
Postemergence applications (after crop emergence) of F9387-1 may cause crop bleaching, leaf speckling in field corn,
yellow popcorn and sweet corn hybrids. Crop bleaching, leaf speckling is typically transitory and has no effect on final
yield or quality. However, herbicide sensitivity in yellow popcorn and sweet corn varies widely, and all yellow popcorn
and sweet corn hybrids have not been tested. Contact your popcorn or sweet corn company, Field man, or University
Specialist about hybrid requirements before making a postemergence application of F9387-1 to yellow popcorn or sweet
corn.
