NOT reuse them. Follow manufacturer’s instructions for cleaning/maintaining PPE. If no such instructions for washables 
exist, use detergent and hot water. Keep and wash PPE separately from other laundry. 
 
 
ENVIRONMENTAL HAZARDS 
 
This pesticide is toxic to fish, aquatic invertebrates, and to some plants at very low concentrations. DO NOT apply directly 
to water, to areas where surface water is present, or to intertidal areas below the mean high-water mark. Drift and runoff 
from treated areas may be hazardous to terrestrial and aquatic plants in neighboring areas. DO NOT contaminate water 
when disposing of equipment wash waters or rinsate. DO NOT discharge effluent containing this active ingredient into 
lakes, streams, ponds, estuaries, oceans, or other waters unless in accordance with the requirements of a National 
Pollutant Discharge Elimination System (NPDES) permit, and the permitting authority has been notified in writing prior 
to discharge. DO NOT discharge effluent containing this product into sewer systems without previously notifying the local 
sewage treatment plant authority. For guidance, contact your State Water Board or Regional Office of the EPA. 
USER SAFETY RECOMMENDATIONS 
USERS MUST: 
x Wash hands thoroughly with soap and water after handling and before eating, drinking, chewing gum, using 
tobacco, or using the toilet. 
x Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. 
x Remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as 
possible, wash thoroughly and change into clean clothing.

Ground Water 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 Advisories: 
 
DO NOT apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high-
water mark. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas. DO NOT 
contaminate water when disposing of equipment wash waters or rinsate. This product may impact surface water quality 
due to runoff of rain water. This is especially true for poorly draining soils and soils with shallow ground water. This 
product is classified as having a high potential for reaching both surface water and aquatic sediment via runoff for several 
months or longer 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 
pyroxasulfone and its degradation product, (5- difluoromethoxy-1H-pyrazol-4-yl) methanesulfone acid (M1), from runoff 
water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall is forecasted to occur 
within 48 hours. 
 
Point Source Contamination: 
 
To prevent point source contamination DO NOT mix or load this or any other pesticide within 50 feet of 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 dike mixing/ loading areas as described below. 
Mixing, loading, rinsing, or washing operations performed within 50 feet of a well are allowed only when conducted on 
an impervious pad constructed to withstand the weight of the heaviest load that may be on or move across the pad. The 
pad must be self-contained to prevent surface water flow over or from the pad. The pad capacity must be maintained at 
110% of that of the largest pesticide container or application equipment used on the pad and has sufficient capacity to 
contain all products spills, equipment or container leaks, equipment wash waters and rainwater that may fall on the pad. 
The containment capacity does not apply to vehicles delivering pesticides shipments to the mixing/ loading site. States 
may have in effect additional requirements regarding wellhead setbacks and operational containment. 
Care must be taken when using this product to prevent back siphoning into wells, spills or improper disposal of excess 
pesticide, spray mixes, or rinsates. Check valves or anti-siphoning devices must be used on all mixing equipment. 
 
Non-target Organism Advisory Statement: 
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. 
 
Endangered Species Protection Requirements: 
 
This product may have effects on federally listed threatened or endangered plant species or their critical habitat. When 
using this product, you must follow the measures contained in the Endangered Species Protection Bulletin for the county 
or parish in which you are applying the pesticide. To determine whether your county or parish has a Bulletin, and to 
obtain that Bulletin, consult “http://www.epa.gov/espp/, or call 1-800-447-3813 no more than 6 months before using this 
product. Applicators must use Bulletins that are in effect in the month in which the pesticide will be applied. New Bulletins 
will generally be available from the above sources 6 months prior to their effective dates. 
Physical/Chemical Hazards

WEED RESISTANCE MANAGEMENT 
F9310-6 Herbicide, contains both a Group 14 (fluthiacet-methyl) and a Group 15 (pyroxasulfone) 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 F9310-6 Herbicide 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 Groups 14 and 
15 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-Groups 14 and 15 herbicides. 
• Avoid making more than two applications of F9310-6 Herbicide and any other Groups 14 and 15 herbicides within 
a single growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum 
for the difficult-to-control weeds. 
• 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. 
 
Glyphosate Resistant Weeds 
 
Some populations of weeds may be resistant to glyphosate-based herbicides. Applying F9310-6 Herbicide in a tank 
mixture with glyphosate for control of emerged resistant weeds larger than specified in Table 10 in a postemergence 
application may result in unsatisfactory control. Follow all directions, restrictions and precautions on the EPA-approved 
label for each product in the tank mixture. 
DIRECTIONS FOR USE 
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Read all Directions for Use 
carefully before applying. 
DO NOT apply this product in a way that will contact workers or other persons, either directly or through drift. Only 
protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult 
the agency responsible for pesticide regulation. 
 
FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS LABEL MAY RESULT IN POOR 
WEED CONTROL, CROP INJURY, OR ILLEGAL RESIDUES. 
AGRICULTURAL USE REQUIREMENTS 
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This 
Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, 
and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and 
emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label 
about personal protective equipment (PPE) and restricted-entry interval. The requirements in this box only apply to uses 
of this product that are covered by the Worker Protection Standard.

PRODUCT INFORMATION 
F9310-6 Herbicide can be applied in all tillage systems (conventional, reduced and no-tillage). F9310-6 Herbicide can 
be applied in the fall or in the spring as a preplant, preplant incorporated, preemergence, or early post emergence 
treatment for susceptible grass and broadleaf weeds in field corn, seed corn, sweet corn, popcorn, and soybeans. F9310-
6 Herbicide may also be used in double cropping and multiple relay inter-cropping.

Weed Size: 
When applying F9310-6 Herbicide alone for post emergent weed control, apply before the weeds have reached the 
maximum height listed in Table 10. Application after weeds have reached the listed maximum height for control could 
result in commercially unacceptable weed control. For control of weeds in post applications larger than listed in Table 
10 and for wider spectrum, apply in tank-mixture with herbicide(s) that are labeled for control of targeted weeds. Uniform 
spray coverage is necessary for optimum performance. 
 
Application Instructions and Timing: 
Moisture is necessary to activate the active ingredient pyroxasulfone in soil for weed control. Dry weather following 
applications of F9310-6 Herbicide may reduce effectiveness. However, when adequate moisture is received after dry 
conditions, F9310-6 Herbicide will control susceptible germinating weeds. F9310-6 Herbicide may not control weeds that 
germinate after application but before an activating rainfall/ irrigation of at least ½ inch, or weeds that germinate through 
cracks resulting from dry soil. When adequate moisture is not received after F9310-6 Herbicide application, weed control 
may be improved by irrigation. DO NOT use on peat or muck soils or mineral soils with 10% or more organic matter 
content. Refer to the crop specific information section for specific application rates, timings and the restrictions and 
limitations by crop and use pattern. 
 
Application Precautions for Post Emergence Applications: 
1. If applying F9310-6 Herbicide post emergence, avoid applications when crop foliage is wet due to heavy dew, 
rain, or irrigation moisture. If F9310-6 Herbicide is applied post emergence, shortly before or soon after rainfall, 
crop response can occur. Recovery from this response is rapid and normal growth is not delayed. Crop yields will 
not be impacted by this crop response. 
2. DO NOT apply if crop is under severe stress due to drought, cold weather, hail, flooding, water-logged or 
compacted soil, disease, insect damage, nutrient deficiency (especially low nitrogen levels), or other causes. 
3. DO NOT tank mix any chlorpyrifos containing insecticide with F9310-6 Herbicide in post applications as crop injury 
might occur. 
4. DO NOT irrigate within 4 hours of a post emergence application of F9310-6 Herbicide. Rainfall or irrigation within 
1 hour may wash F9310-6 Herbicide off of the weeds during this period and may reduce post emergence 
performance. 
5. Observe all precautions and limitations on the label of each product used in tank mixture with F9310-6 Herbicide. 
 
Restrictions 
• DO NOT apply this product through any type of irrigation system. 
• DO NOT use flood irrigation to apply, activate or incorporate this product. 
• DO NOT make more than 1 preemergence application to spring corn or soybeans. 
• DO NOT harvest or feed field corn forage until 30 days after the last application of F9310-6 Herbicide. 
• DO NOT harvest or feed sweet corn forage or ears until 40 days after the last application of F9310-6 Herbicide. 
• DO NOT harvest or feed corn grain or stover (fodder) until 70 days after the last application of F9310-6 Herbicide. 
• DO NOT graze or feed treated soybean forage or hay to livestock. 
 
 
Ground Application 
Use sufficient spray pressure and spray volume for accurate and uniform application. Refer to instructions for the spray 
equipment used to determine the actual minimum volume. The carrier may be either water or a sprayable fluid fertilizer. 
DO NOT apply this product without dilution in a spray carrier. Apply F9310-6 Herbicide in a minimum of 5 gallons of 
water per acre or 10 or more gallons of sprayable fluid nitrogen fertilizer per treated acre for weed control applications. 
For postemergence applications, apply F9310-6 Herbicide in a minimum of 10 gallons per acre of finished spray solution. 
If a dense crop and/or weed canopy is present, use up to 40 gallons of spray solution per acre. 
 
Aerial Application 
Use nozzle types and arrangement that will provide optimum coverage and minimize drift potential. Apply at a minimum 
of 3 gallons per acre of finished spray solution. For dense weed populations or heavy crop canopy, a higher spray volume 
may be required to obtain adequate spray coverage.

Proper Handling Instructions 
This product may 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. 
 
MIXING AND LOADING INSTRUCTIONS 
 
Mixing Instructions: 
1. The spray equipment must be clean before using this product. If it is contaminated with other materials, mixing 
problems and/or clogging can occur and/or crop response can occur. 
 
2. Prepare no more spray mixture than is needed for the immediate application. Applying the product immediately 
after preparation ensures that it is in suspension. If application is delayed, agitation to re-mix the products and 
checking for resuspension ensures proper blending.

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 F9310-6 Herbicide 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 and/or fertilizer. 
 
5. Complete filling the tank with clean water and/or fertilizer to 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. 
 
Mixing F9310-6 Herbicide in Tank Mixtures with Other Herbicides and Fluid Fertilizers 
F9310-6 Herbicide is compatible with most commonly used herbicides, insecticides, fungicides, and spray adjuvants. It 
is the pesticide user's responsibility to ensure that all products are registered for the intended use. BEFORE MIXING 
F9310-6 Herbicide WITH OTHER REGISTERED PRODUCTS FOR ANY USE ON THIS LABEL, READ THE LABEL 
OF THE TANK MIX PARTNER TO BE CERTAIN IT IS LABELED FOR THE USE ON THE TARGET CROP AND THAT 
USE PATTERNS ARE COMPATIBLE WITH THOSE OF F9310-6 Herbicide. When using F9310-6 Herbicide in a tank 
mixture with other pesticides, users must observe the most restrictive label limitations and precautionary statements of 
each product in the tank mixture. Read and follow the applicable restrictions and limitations and directions for use on all 
product labels involved in tank mixing. 
F9310-6 Herbicide can be used with commonly used clear fluid nitrogen fertilizers (e.g. 28% or 32% UAN). It is 
recommended that a preliminary compatibility jar test be conducted using appropriate ratios of F9310-6 Herbicide and 
fertilizer. 
Prepare no more spray mixture than is needed for the immediate application. Applying the product

immediately after preparation ensures that it is in suspension. If application is delayed, agitation to re-mix the products 
and checking for resuspension ensures proper blending. 
Compatibility Test 
A jar test is advised before mixing to ensure F9310-6 Herbicide 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 for the tank mixture, replace and tighten lids. Shake jars by inverting the mixture and 
then let stand for 15 to 30 minutes. 
 
5. After waiting period, check jars for separation, precipitates, flakes, films on the side, gels or other signs of 
incompatibility. If mixtures separate but can be remixed, the mixture can be sprayed as long as good agitation 
is used. 
 
6. If the mixtures are incompatible, then try these methods to overcome the problem. A) Make a slurry of dry 
pesticides in water before adding them to the tank B) Add more compatibility agent or increase the water volume 
of the mixture. 
 
7. If tank mixtures are incompatible, then DO NOT spray the mixture. 
After compatibility testing is complete, dispose of any testing jars and pesticide wastes according to the Pesticide Storage 
and Disposal section of this label. 
 
Spray adjuvants for burndown and post applications 
An adjuvant or a product containing an adjuvant approved for use on soybean crops may be used with F9310-6 Herbicide 
for maximum consistent performance. 
 
Adjuvants for F9310-6 Herbicide: 
Use a spray adjuvant from one of these classes for optimum performance for burndown or post applications. 
Non-ionic surfactant (NIS) - must have a minimum of 80% of the constituents effective as spray adjuvant at the rate of 
1 quart/100 gallons of spray volume (concentration of 0.25%). 
Crop Oil Concentrate (COC) or Methylated Seed oil (MSO) - petroleum or vegetable-based oil containing not less 
than 12% emulsifier. Use 1-2 pts. /A and the concentration must not exceed 2.5% volume/volume. COC/MSO may 
improve performance under dry conditions and low relative humidity. 
Silicone-based surfactant - apply at a rate of 1 qt/100 gallons or a spray volume concentration of 0.25% or as specified 
on the adjuvant label. 
In addition to an adjuvant, urea ammonium nitrate (UAN) at 1-2 qts./A or spray grade ammonium sulfate (AMS) at 
specified use rates may also be added to the spray solution. 
Adjuvants for F9310-6 Herbicide in Tank Mixtures with Other Herbicides: 
When tank mixing with other herbicides, use the adjuvant specified for use with the tank mix partner. Follow all restrictions 
and precautions on the tank mix partner’s label.

DRY FERTILIZER APPLICATION 
F9310-6 Herbicide may be impregnated or coated onto dry bulk granular fertilizer carriers for fall and preplant surface 
and preplant incorporated applications. Follow all F9310-6 Herbicide label recommendations, instructions and 
precautions. All individual state regulations relating to dry granular fertilizer blending, registration, labeling and application 
are the responsibility of the individual and/or company selling the herbicide/ fertilizer mixture. Select the F9310-6 
Herbicide application rate per acre from this label and determine the quantity of dry bulk fertilizer to be applied per acre 
(use a minimum of 200 pounds and a maximum of 750 pounds per acre). 
 
Use the equation below to determine the amount of F9310-6 Herbicide needed per ton of fertilizer applied. 
 
(fl oz of F9310-6 Herbicide per acre X 2000) / pounds fertilizer per acre = fl oz of F9310-6 Herbicide for 1 ton of fertilizer. 
 
F9310-6 Herbicide may be impregnated on many commonly used dry fertilizer but DO NOT impregnate on ammonium 
nitrate, fertilizers containing ammonium nitrate, potassium nitrate, sodium nitrate or powdered limestone. 
To impregnate F9310-6 Herbicide on bulk fertilizer, use a closed rotary drum mixer or other commonly used dry bulk 
fertilizer blender equipped with suitable spray equipment. Mix F9310-6 Herbicide with sufficient water to form a sprayable 
slurry mixture. Orient spray nozzles to provide uniform fertilizer coverage while avoiding spray contact with mixing 
equipment. Non-uniform impregnation can cause crop injury or unsatisfactory performance. 
 
Spray the herbicide mixture onto the fertilizer after blending has started. If necessary, include a suitable drying agent to 
ensure a spreadable herbicide impregnated fertilizer. Apply treated fertilizer immediately after impregnation to avoid 
lump formulation and spreading difficulties. Accurate calibration of fertilizer application equipment and uniform fertilizer 
distribution is essential for satisfactory weed control. Apply the mixture uniformly to the soil with proper equipment 
immediately after blending and moisture is required for activation.

APPLICATION TIMING 
Fall Applications for controlling weeds germinating the following spring 
F9310-6 Herbicide may be applied in the fall to control weeds in conventional, minimum tillage, or no-till corn production 
systems planted the following spring. This fall application program will typically need to be followed with a suitable in-
season postemergence herbicide treatment to provide season long control of the complete target weed spectrum. On 
medium soils use 9 to 10 fl oz/A of F9310-6 Herbicide (0.146 - 0.163 lb ai/A pyroxasulfone, 0.0044 - 0.0049 lb ai/A 
fluthiacet-methyl). On fine soils use 10 to 13 fl oz/A of F9310-6 Herbicide (0.163 - 0.212 lb ai/A pyroxasulfone, 0.0049 - 
0.0064 lb ai/A fluthiacet-methyl) in corn and 10 to 11.4 fl oz/A (0.163 - 0.186 lb ai/A pyroxasulfone, 0.0049 - 0.0056 lb 
ai/A fluthiacet-methyl) in soybeans. 
Fall Applications for controlling weeds germinating in the fall or winter annual weeds 
F9310-6 Herbicide may be applied in the fall for burndown and residual control. For control of emerged weeds in the fall 
use combinations with other burndown herbicides like Aim (EPA Reg. No. 279-3241,Carfentrazone-ethyl), 2,4-D, 
dicamba, glyphosate, paraquat or glufosinate. Follow all directions, restrictions and precautions on the EPA-approved 
label for each product in the tank mixture. If a se quential application program (fall application followed by spring 
application of F9310-6 Herbicide) is used, the maximum combined rate of F9310-6 Herbicide must not exceed 16.3 fl 
oz/A 0.266 lb ai/A pyroxasulfone and 0.008 lb ai/A fluthiacet-methyl) per year for corn and 11.4 fl oz/A 0.186 lb ai/A 
pyroxasulfone and 0.0056 lb ai/A fluthiacet-methyl) per year in soybeans. DO NOT exceed 2-inch incorporation depth if 
tilled after application. Use the highest rate within soil type. F9310-6 Herbicide may be broadcast surface applied in the

fall after crop harvest when soil temperatures at the 4-inch depth are sustained at less than 55º F and before the ground 
freezes to control weeds in minimum or no tillage fields planted the following spring. Fall applications must be made after 
October 1. DO NOT apply to frozen or snow-covered soil. 
Preplant, preemergence and early preplant applications 
F9310-6 Herbicide may be applied prior to planting up to crop emergence. Apply F9310-6 Herbicide alone or in tank 
mixtures, up to 45 days before planting. See specific crop sections for further directions and use rates. For popcorn and 
sweet corn, preplant surface applications are not recommended on coarse soils, in areas where average annual rainfall 
(or rainfall + irrigation) typically exceeds 40 inches, or for popcorn or sweet corn. Cultivation or a labeled postemergence 
herbicide application may still be required under certain conditions for complete weed control.
 
 
If weeds are present at the time of application, use additional weed control methods including tank mixes with an 
appropriate postemergence herbicide(s) to control emerged weeds and follow all label directions, rates, restrictions, and 
precautions on the tank mixture partner labeling. 
 
Preplant incorporated (PPI) applications 
For PPI applications of F9310-6 Herbicide incorporate into the upper (1-2”) soil surface up to 14 days before planting. 
Deeper incorporation may increase the potential for crop injury and also may result in reduced weed control. Use 
appropriate equipment that provides uniform shallow incorporation, such as a field cultivator, harrow, rolling cultivator or 
finishing disc. 
 
Early Post emergence applications 
In corn, apply F9310-6 Herbicide from crop emergence through V4 stage (visible 4
th leaf collar). In soybeans, apply 
F9310-6 Herbicide from planting through the third trifoliate (V3) leaf stage. The amount of F9310-6 Herbicide to apply 
and the degree of weed control resulting from a F9310-6 Herbicide application depends upon a variety of factors such 
as weeds present, stage of growth of the weeds, environmental conditions, growing conditions and soil type. 
Under stressful growing conditions, (i.e. saturated soils, cold soil temperatures, slow growth, etc) the crop may 
experience higher risk for temporary crop response. The crop will rapidly outgrow these effects and develop normally 
with no reduction in yield. 
Before applying to corn, verification of F9310-6 Herbicide selectivity on your inbred line or hybrid line must be confirmed 
with your local seed company or supplier to avoid injury to sensitive inbreds or hybrids. 
Split applications 
F9310-6 Herbicide can be applied in sequential programs, but DO NOT exceed the maximum use rate per year. DO 
NOT exceed a maximum of 16.3 fl oz/A (0.266 lb ai/A pyroxasulfone and 0.008 lb ai/A fluthiacet-methyl) per year in corn. 
On coarse soils DO NOT apply more than a maximum cumulative amount of 6.8 fl oz/A F9310-6 Herbicide (0.111 lb ai/A 
pyroxasulfone and 0.0033 lb ai/A fluthiacet-methyl) per year in soybeans. On other soybean soils DO NOT apply more 
than a cumulative amount of 11.4 fl oz/A (0.186 lb ai/A pyroxasulfone and 0.0056 lb ai/A fluthiacet-methyl) per year in 
soybeans. Where weeds are emerged, use appropriate tank mixtures for control of the weed species present. Separate 
sequential applications by at least 14 days. 
 
F9310-6 Herbicide in Tank Mixtures 
For enhanced control of emerged weeds use F9310-6 Herbicide in combination with other labeled burndown herbicide 
products for the crop like Aim
® EC Herbicide (EPA Reg. No. 279-3241, Carfentrazone-ethyl), 2,4-D, dicamba, glyphosate, 
paraquat, glufosinate and products containing saflufenacil (e.g. Sharpen ® (EPA Reg. No. 7969-278, Saflufenacil) 
Verdict®, (EPA Reg. No. 7969-279, Dimethenamid-P + Saflufenacil) or OpTill® (EPA Reg. No. 7969-280, Imazethapyr + 
Saflufenacil). Saflufenacil may be applied prior to planting at any time in combination with F9310-6. 
 
F9310-6 Herbicide may be applied pre and post emergence with glufosinate or glyphosate-based products, or other pre 
and postemergence broadleaf herbicides approved for use on corn. Tank mixing F9310-6 Herbicide with other 
postemergence herbicides may increase the speed of activity and provide control of the weeds listed in Table 10. F9310-
6 Herbicide may be tank-mixed with labeled insecticides for that crop such as Hero ® Insecticide (EPA Reg. No. 279-
3315, Bifenthrin + Zeta-Cypermethrin), or Mustang ® Maxx (EPA Reg. No. 279-3426, Zeta-Cypermethrin) and with 
labeled fungicides. Some populations of weeds may be resistant to glyphosate-based herbicides. Applying F9310-6 
Herbicide in a tank-mix with glyphosate on resistant weeds larger than specified in Table 10 may result in unsatisfactory 
control. Other herbicides in tank-mix with F9310-6 Herbicide or separately may be required to achieve adequate control 
of these resistant biotypes. Follow all directions, restrictions and precautions on the EPA-approved label for each product 
in the tank mixture and follow the most restrictive requirements of the products being mixed.

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 must select nozzle and pressure
that deliver coarse or coarser droplets in accordance with American Society of Agricultural & Biological
Engineers Standard 572 (ASAE S572).
• For all other applications, applicators must select nozzle and pressure that deliver medium or coarser droplets
in accordance with American Society of Agricultural & Biological Engineers Standard 572 (ASAE S572).
• DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
• DO NOT apply during temperature inversions.
Aerial Applications: 
• DO NOT release spray at a height greater than 10 feet above the vegetative canopy, unless a greater 
application height is necessary for pilot safety.
• For applications prior to the emergence of crops and target weeds, applicators must select nozzle and pressure 
that deliver coarse or coarser droplets in accordance with American Society of Agricultural & Biological 
Engineers Standard 641(ASABE S641).
• For all other applications, 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).
• The boom length must be 75% or less of the wingspan for fi xed-wing aircraft and 90% or less of the rotor 
diameter for helicopters.
• Applicators must use a minimum of one-half swath displacement upwind at the downwind edge of the field.
• Nozzles must be oriented so the spray is directed toward the back of the aircraft.
• 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.
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 
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. 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. 
 
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 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). 
 
CLEANING SPRAY EQUIPMENT 
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 F9310-6 Herbicide 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 F9310-6 Herbicide 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. 
5. Properly dispose of all cleaning solution and rinsate in accordance with Federal, State, and local regulations and 
guidelines. 
DO NOT apply sprayer cleaning solutions or rinsate to sensitive crops. 
DO NOT store the sprayer for any extended period of time with F9310-6 Herbicide spray solution remaining in the tank, 
spray lines, spray boom plumbing, spray nozzles or strainers.

If the sprayer has been stored or idle, purge the spray boom and nozzles with clean water before beginning any 
application. 
Should small quantities of F9310-6 Herbicide remain in inadequately cleaned mixing, loading and/or spray equipment, 
they may be released during subsequent applications potentially causing effects to certain crops and other vegetation. 
To the extent consistent with applicable law, FMC accepts no liability for any effects due to inadequately cleaned 
equipment. 
When F9310-6 Herbicide has been tank mixed refer to the label of the product used previously, or tank mixed with 
F9310-6 Herbicide for cleaning instructions. 
REPLANTING INSTRUCTIONS 
If corn or soybeans treated with F9310-6 Herbicide is lost due to a natural catastrophe such as hail or frost, corn or 
soybeans can be replanted immediately, provided this is not restricted on the label of a product used previously or by a 
product applied in a tank mixture with F9310-6 Herbicide.
