PRODUCT INFORMATION 
 
F4044-2 is a selective herbicide that may be preplant surface-applied, preplant incorporated, 
preemergence, or postemergence treatment in water or li quid fertilizer for control of most annual grasses 
and certain broadleaf weeds in soybean, cotton, field corn, sweet corn, and popcorn. F4044-2 can be applied 
in all tillage systems (conventional, reduced and no-tillage). F4044-2 can be applied in the fall or in the spring as 
a preplant, preplant incorporated, preemergence, or early postemergence treatment for susceptible grass and 
broadleaf weeds. 
 
This product will not control emerged weeds. If weeds are emerged at the time of application, apply a labeled 
postemergence herbicide or utilize tillage to control emerged weeds. Dry weather following preemergence 
application of F4044-2 or a tank-mixture may reduce effectiveness. If F4044-2 is incorporated, any supplemental 
tillage before planting must not exceed the depth of incorporation. Crop injury may occur following the use of 
F4044-2 under stress conditions such as cold weather, hail, flooding, water-logged or compacted soil, 
disease or insect damage, or nutrient deficiencies during early development of the crop. 
 
 
Restrictions 
x Do not use in nurseries, on turf, or on landscape plantings. 
x Do not apply to non-target areas under conditions which favor runoff or wind erosion of soil containing 
this product. 
 
To prevent off-site movement due to runoff or wind erosion: 
 
1. Do not treat on powdery dry or light sand soils when conditions are favorable for wind erosion. Under these 
conditions, ensure that the soil surface is settled by rainfall or irrigation. 
 
2. Do not apply to impervious substrates, such as paved or highly compacted surfaces. 
 
3. Do not use tailwater from the first flood or furrow irrigation of treated fields to treat non-target crops, unless at 
least ½-inch of rainfall has occurred between application and the first irrigation. 
 
4. Application of this product followed by poor crop growing conditions such as cold, wet soil stress or waterlogged 
conditions from excessive rainfall or irrigation may result in crop response. Tank-mixes with other residual

[Optional text appears in brackets] 
 
5 
herbicides may also increase the potential for crop injury. 
 
5. Before applying to the labeled crop, verification of F4044-2 selectivity on your variety must be confirmed to 
avoid injury to sensitive varieties. Check with the state Cooperative Extension Service for information on 
potential F4044-2 varietal sensitivity. If variety tolerance is unknown, such as with new varieties, apply F4044-
2 on a small area to confirm variety safety before use on large acreage. 
 WEED RESISTANCE MANAGEMENT 
F4044-2, which contains the active ingredient pethoxamid is a group 15 herbicide based on the mode 
of action classification system of the Weed Scie nce 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 ov erlapping 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, follow as many of these herbicide 
resistance management practices as is practical: 
• 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 rela tively small (less than 4 inches). 
• Apply full rates of F4044-2 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 reproduc e 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 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. 
• 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 15 herbicides. 
• Avoid making more than two applications of F4 044-2 and any other Group 15 herbicides within a 
single growing season unless mixed with an herb icide 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 be fore leaving fields suspected to contain resistant 
weeds.

[Optional text appears in brackets]

• Manage weeds in and around fields, during and after harvest to reduce weed seed production. 
 
High Weed Pressure 
Where a use rate range is given, use the higher ra te of F4044-2 when weed pressure is high and/or 
conditions are favorable for weed development. 
 
F4044-2 APPLIED ALONE 
 
Weeds Controlled 
F4044-2 is taken up by the shoots and/or roots of emerging weeds. This uptake results in the inhibition of 
shoot and root tissue growth soon after weed germination. F4044-2 alone will not control emerged weeds 
and must be applied prior to weed emergence. If F4044-2 is incorporated, do not exceed a depth of 2-3 
inches. Any tillage after the F4044-2 incorporation and before planting must not exceed 2-3 inches. 
 
Where reference is made to weed “suppression”, this can either mean inconsiste nt efficacy (ranging from 
poor to good control), or efficacy that is consistent, bu t below levels generally considered as good control. 
Control of these weeds can be erratic, due partially to variable weather conditions. Dry weather following 
application of F4044-2 may reduce weed control. The following procedures may improve the control of 
weeds listed as partially controlled in Table 2: 
 
1. Thoroughly till soil to destroy germinating and emerged weeds. 
 
2. Plant crop into moist soil immediately after tillag e. If F4044-2 is to be used preemergence, apply 
at planting or immediately after planting. 
 
3. If available, sprinkler irrigate with ½ inch water within 7 days after application. Refer to the section 
on Center Pivot Irrigation Application for this method of applying F4044-2. 
 
4. If irrigation is not possible and rain does not occur within 7 days after planting and application, weed 
control may be reduced. Under these conditions, perform a uniform, shallow cultivation as soon 
as weeds emerge. 
 
Application Instructions and Timings 
F4044-2 may be applied alone or in tank-mixtures with other labeled herbicides for weed control in labeled crops 
at various times. Refer to the given crop section of the label to determine if application timings listed below are 
permitted. 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 tank mixture. Tank-mixtures are permitted only in states where the tank-mix partner is registered. 
 
Preplant surface-applied: For minimum tillage or no-tillage systems only, F4044-2 alone and F4044-2 tank-
mixtures may be applied up to 30 days before planting certain crops. Treatments less than 30 days before 
planting may be made either as a split or a single application. Refer to individual crop section on this label to 
determine if early preplant surface application is permitted. If weeds are present at the time of treatment, apply 
in a tank-mixture combination with a contact herbicide. Observe Directions for Use, Precautions, and Restrictions 
on the label of the contact herbicide. To the extent possible, do not move treated soil out of the row or move 
untreated soil to the surface during planting, or reduced weed control can result. 
 
Preplant incorporated: Apply F4044-2 to the soil surface and incorporate into the top 1-2 inches of soil within 
14 days before planting using a harrow, rolling cultivator, finishing disk, or similar implement capable of providing 
uniform incorporation. Use a preplant incorporation application if furrow irrigation is used or when a period of dry 
weather after application is expected. If crop is to be planted on beds, apply and incorporate F4044-2 after 
formation of beds, unless specified otherwise. 
 
Preemergence: Surface Apply F4044-2 during planting or after planting, but before weeds or crops emerge.

[Optional text appears in brackets] 
 
7 
Postemergence: Because F4044-2 will not control emerged weeds, F4044-2 must be applied to a weed-free 
soil surface or in tank-mixture with products that provide postemergence control of weeds present at the time of 
application. Refer to the individual crop sections of this label if a postemergence application is permitted. 
 
Note: Moisture is necessary to activate the active ingredient pethoxamid in soil for weed control. Dry weather 
following applications of F4044-2 may reduce effectiveness. However, when adequate moisture is received after 
dry conditions, F4044-2 will control susceptible germinating weeds. F4044-2 may not control weeds that 
germinate after application but before an activating rainfall or irrigation of at least ½ inch, or weeds that germinate 
through cracks resulting from dry soil. When adequate moisture is not received after F4044-2 application, weed 
control may be improved by irrigation. Do not use on peat or muck soils and 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.

2 applied in the fall plus the spring must not exceed the maximum annual rate for the specific crop planted, 
or illegal residues may result. 4) Refer to the crop sections on this label for specific directions. 
 
Ground Application: Apply F4044-2 alone or in tank mixtures by ground equipment in a minimum of 10 
gallons of spray solution per acre, unless otherwise specified. 
 
Use sprayers that provide accurate and uniform appl ication. For F4044-2 tank mixtures with wettable 
powder or dry flowable formulations, screens and strain ers used for application must be no finer than 50-
mesh. Rinse sprayer thoroughly with clean water immediately after use. 
 
Banded Applications: Calculate the amount of herbicide needed for band treatment by using the following 
formula: 
band width in inches X broadcast rate per 
acre = amount needed 
per acre of field 
row width in inches 
 
APPLICATION INFORMATION AND CROP RESTRICTION/LIMITATIONS 
 
Ground Application 
Use sufficient spray volume and spray pressure for accurate and uniform application. Refer to instructions for the 
spray equipment used to determine the actual minimum volume. Do not apply F4044-2 without dilution in a spray 
carrier. The carrier may be either water or liquid fertilizer. Apply F4044-2 in a minimum of 10 gallons of water or 
sprayable liquid fertilizer per treated acre. Rinse sprayer thoroughly with clean water immediately after use. 
 
Aerial Application 
Use nozzle types and arrangement that will provide optimum coverage and minimize drift potential. Apply 
with in minimum of 5 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. 
 
The following measures must be followed to reduce the potential of spray drift to non-target areas from 
aerial applications. 
 
1. The distance of the outermost nozzles on the boom must not exceed ¾ the length of the wingspan or 
90% of the rotor blade diameter. 
2. Use low drift nozzles such as straight-stream that produce coarse to very coarse droplets.

[Optional text appears in brackets] 
 
10 
3. Nozzles must always be backward, parallel with the airstream and never pointed downward more than 
45 degrees. 
4. Without compromising aircraft safety, application must be made at a height of 10 ft. or less above the 
crop canopy. Applicators must follow the most restrictive precautions to avoid drift hazards including 
those found in this labeling as well as applicable state and local regulations and ordinances. 
5. Do not apply during periods of temperatures inversions. 
6. Avoid potential adverse effects to non-target areas by maintaining a 30 ft buffer between the application 
area and the closest downwind edge of sensitive terr estrial habitats (such as grasslands, forested 
areas, shelter belts, woodlots, hedgerows, riparian areas, shrub lands, and crop lands). 
 
The applicator must be familiar with and take into account the information covered in the Spray Drift 
Management section below. 
 
SPRAY DRIFT MANAGEMENT 
 
AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR 
AND THE GROWER. 
 
Avoid any drift conditions that would allow the produc t to contact desirable vegetation. F4044-2 is not 
volatile, however; mist from spray drift may cause injury to sensitive plants. The interaction of equipment 
and weather related factors determine the potential fo r spray drift. The applicator and the grower are 
responsible for considering all these factors involved in minimizing drift potential when making decisions. 
The following drift management requirements must be followed to avoid off-target movement from 
applications to agricultural field crops. These requir ements do not apply to forestry applications, public 
health uses or to applications of dry materials. 
 
Where states have more stringent regulations, they must be observed. 
 
Information on Droplet Size 
The best drift management strategy is to apply the la rgest droplets that provide sufficient coverage and 
control. Use nozzle types arrangements that will pr ovide maximum coverage and minimize the potential 
for off target movement of spray particles. Droplets si ze for ground applications must be in the medium to 
extremely coarse size catego ries as defined in the August 1999 AS AE S572 publication entitled, “Spray 
Nozzle Classification by Drop Spectra”. Refer to that publication for additional information. For aerial 
application, low drift or straight stream nozzles that deliver coarse to very coarse droplets are required. 
Regardless of droplet size, if applications are ma de improperly or under unfavorable environmental 
conditions off target movement will occur. (see Wind, Temperature and Hum idity, and Temperature 
Inversion sections in this label). 
 
Controlling Spray Droplet Size 
 
VMD (Volume median diameter) – VMD is the expression of the droplet size of the spray cloud. The VMD 
value means that 50% of the droplets are larger th an the expressed value and 50% of the droplets are 
smaller than the expressed value. Optimum F4044-2 spray clouds should be 450 microns with fewer than 
10% of the droplets being 200 microns or less. 
 
Volume - Use high flow rate nozzles that produce medium droplets to apply the highest practical spray 
volume. 
 
Pressure - Use the lower spray pressures recommended for the nozzle and do not exceed the 
manufacture’s recommended pressure. Higher pressure reduces droplet size and does not improve canopy 
penetration. When higher flow rates are needed, use higher flow rate nozzles instead of increasing 
pressure. 
 
Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage.

[Optional text appears in brackets] 
 
11 
Nozzle Orientation – Orienting nozzles so that the spray is rele ased backwards parallel to the air-stream 
will produce larger droplets than other orientations. Significant deflection from horizontal will reduce droplet 
size and increase drift potential. 
 
Nozzle Type - Use a low drift nozzle type that is designed for the intended application. Do not use nozzles 
that produce fine or very fine spray droplets (e.g. cone). 
 
Ground Boom Application Height - Do not make applications at a height greater than 4 feet above the 
top of the largest plants. Making applications at the lowest possible height reduces exposure of droplets to 
evaporation and wind. 
 
Aerial Application Height – Apply at a height of 10 ft or less above the crop canopy unless aircraft safety 
is compromised. Applicators must follow the most restrictive use cautions to avoid drift hazards, including 
those on this label as well as state and local regulations. 
 
Swath Adjustment - When applications are made with cross wind, the swath will be displaced downwind. 
Therefore, on the up and downwind edges of the field, the applicator must compensate for this displacement 
by adjusting the path upwind. Swath adjustment dist ance must increase with increasing drift potential 
(higher wind, smaller drops, etc). 
 
Wind - Variable wind speeds with changing directions ma y pose the largest potential for drift damage if 
crops other than rice are adjacent to the field to be sprayed. Drift potential is lowest between wind speeds 
of 2 to 10 mph. However, many factors, including droplet size and equipment type determine drift potential 
at any given speed. Applications mu st be avoided if wind speed is below 2 mph due to variable wind 
direction and high inversion potential. Do not to apply F4044-2 when wind speed exceeds 15 mph. NOTE: 
Local terrain can influence wind patt erns. Every applicator shall be familiar with local wind patterns and 
how they affect spray drift. 
 
Temperature and Humidity - When making applications in low relative humidity set up equipment to 
produce larger droplets to compensate for evaporation, but they still should remain within the medium 
droplet size category. Droplet evaporation is most severe when conditions are both hot and dry. 
 
Temperature Inversions – Do not apply at times when spray particles may be entrained into a temperature 
inversion layer. If inversion conditions are suspected, consult with local weather services before making an 
application. Applications must not occur during temp erature inversion, because drift potential is high. 
Temperature inversions restrict vertical air mixing, whi ch causes small suspended droplets to remain in a 
concentrated cloud. This cloud can move in unpred ictable directions due to the light variable winds 
common during inversions. Temperature inversions are characterized by increasing temperatures with 
altitude and are common on nights with limited cloud cover and light to no wind. They begin to form as the 
sun sets and often continue into the following morning. Their presence can be indicated by ground fog. 
However, if fog is not present, inversions can also be identified 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. 
 
Sensitive Areas – The pesticide must only be applied when the potential for drift to adjacent sensitive 
areas (e.g., residential areas, bodies of water, kno wn habitat for threatened or endangered species, 
nontarget crops) is minimal (e.g., when wind is blowing away from the sensitive areas). Avoid application 
to humans or animals. Flagmen and loaders must avoid inhalation of spray mist and prolonged contact with 
skin. 
 
Center pivot irrigation application — F4044-2 alone or in tank mixture with other herbicides which are 
registered for center pivot application may be applied in irrigation water preemergence at rates as listed on 
this label. F4044-2 also may be applied postemergenc e to the crop and preemergence to weeds in crops 
where postemergence applications are allowed on this label. Follow all restrictions to avoid illegal residues. 
Do not apply this product through any other type of irriga tion system other than center pivot. Crop injury,

[Optional text appears in brackets] 
 
12 
reduced weed control, or illegal pesticide residues in the crop can result from nonuniform distribution of 
treated water. If you have questions about calibra tion, you should contact State Extension Service, 
equipment manufacturers, or other experts. Do not connect an irrigation system (including greenhouse 
systems) used for pesticide application to a public water system, unless the pesticide label-prescribed 
safety devices for public water systems are in place. A person knowledgeable of the chemigation system 
and responsible for its operation, or under the supervision of the responsible person, shall shut the system 
down and make necessary adjustments should the need arise. 
 
DRY FERTILIZER APPLICATION 
 
F4044-2 may be impregnated or coated onto dry bulk granular fertilizer carriers for fall and preplant surface and 
preplant incorporated applications. Follow all F4044-2 label restrictions, instructions and precautions. 
 
The individual and/or company selling the herbicide/fertilizer mixture should ensure all individual state regulations 
relating to dry granular fertilizer blending, registration, labeling, and application are followed. 
 
Select the F4044-2 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 700 pounds per acre). Use the equation 
below to determine the amount of F4044-2 needed per ton of fertilizer applied. 
 
(fl. oz. of F4044-2 per acre X 2000) 
_______________________________ 
= fl. oz. of F4044-2 for 1 
ton of fertilizer Pounds fertilizer per acre 
 
F4044-2 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 F4044-2 on bulk fertilizer, use a closed rotary drum mixer or other commonly used dry bulk fertilizer 
blender equipped with suitable spray equipment. Mix F4044-2 with sufficient water to form a sprayable slurry 
mixture. Spray nozzles be directed 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. 
 
Fertilizer Impregnation Restrictions 
Impregnation of F4044-2 is restricted to commercial facilities. On-farm fertilizer impregnation is prohibited. No 
more than 500 tons of bulk fertilizer can be impregnated per day. No single facility may impregnate fertilizer with 
this product for more than 30 days per calendar year. 
 
Application to Fertilizer 
Apply 200-700 lbs. of the herbicide/fertilizer mixture per acre. For best results, apply the mixture uniformly 
to the soil with properly calibrated equipment imme diately after blending. Uniform application of the 
herbicide/fertilizer mixture is essential to prevent po ssible crop injury. Non-uniform application may result 
in poor weed control. In areas where conventional tillage is practiced, shallow incorporation of the mixture 
into the soil may improve weed control. 
 
Precaution: To avoid crop injury, do not use the herbicide/fertilizer mixture on crops where bedding is used.

MIXING AND LOADING INSTRUCTIONS 
 
F4044-2 Alone 
Mix F4044-2 with water or liquid fertilizer and apply as a spray. Fill the spray tank half to ¾ full with water 
or liquid fertilizer, add the proper amount of F4044-2, th en add the rest of the water or liquid fertilizer. 
Ensure sufficient agitation is used during mixing and application to maintain a uniform solution. 
 
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. 
 
3. Maintain maximum agitation throughout the spraying operation. 
 
4. Flush the spray equipment thoroughly after each use and apply rinsate to an appropriate area. 
 
Mixing Steps: 
1. Add 1/4 -1/2 of the required amount of clean water and/or fertilizer 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 F4044-2 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 (for burndown applications only) 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 F4044-2 in Tank-mixtures with Other Herbicides and Liquid Fertilizers 
F4044-2 is compatible with most commonly used herbicides, insecticides, fungicides, and spray adjuvants. 
Although F4044-2 is compatible with most products, not all combinations have been tested. Before applying 
any tank mixture not specifically listed on this label, the crop safety of the target crop should be confirmed 
by applying the mixture to a small area of the target crop in accordance to the label instructions. It is the 
pesticide user’s responsibility to ensure that all pro ducts 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. 
 
 BEFORE MIXING F4044-2 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 USE ON THE TARGET 
CROP AND THAT USE PATTERNS ARE COMPATIBLE WITH THOSE OF F4044-2. When using F4044-2 in 
a tank-mixture with other pesticides, observe the most restrictive label limitations and precautions for the products 
being used.

[Optional text appears in brackets] 
 
14 
F4044-2 can be used with commonly used clear liquid nitrogen fertilizers (e.g. 28% or 32% UAN). It may be 
necessary to prepare a dilution of F4044-2 and water before adding it to the liquid fertilizer mix. It may also be 
mixed with other liquid fertilizers, however, it is recommended that a preliminary compatibility jar test be conducted 
using appropriate ratios of F4044-2 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 Jar Test: 
Perform a jar test before mixing to ensure F4044-2 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 (for burndown applications only). After each addition, 
shake or stir gently to thoroughly mix. 
(Dry Herbicides and Adjuvants (for burndown applications only): For each pound to be applied per acre, add 
1.4 tsp. to each jar. Liquid Herbicides and Adjuvants (for burndown applications only): 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. (Properly dispose of testing jars and any 
pesticide waste). 
 
Use of Adjuvants: 
An adjuvant may be used with F4044-2 unless otherwise specified in the crop use directions. F4044-2 is 
compatible with most products, however not all have been tested. Use the compatibility jar test above to 
ensure physical compatibility. 
 
Early preplant and preemergence surface applications: 
F4044-2 may be applied prior to planting up to crop emergence. Apply F4044-2 alone or in tank-mixtures, up to 
30 days before planting. 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, tank-mix an appropriate postemergence or burndown herbicide(s) 
to control emerged weeds and follow all label directions, rates, restrictions, and precautions on the tank mixture 
partner labeling. Before applying to corn, verification of F4044-2 selectivity on your inbred line or hybrid line must 
be confirmed with your local seed company or supplier to avoid injury to sensitive inbred lines or hybrids.

[Optional text appears in brackets] 
 
15 
Preplant incorporated (PPI) applications: 
For PPI applications of F4044-2 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. 
 
Postemergence and Layby applications: 
Apply F4044-2 postemergence-layby for additional residual on later flushes of weeds that can emerge in-season. 
The amount of F4044-2 to apply and the degree of weed control resulting from application depends upon a variety 
of factors such as weeds present in the field, environmental conditions, growing conditions and soil type. Moisture 
is necessary to incorporate the active ingredient in the soil for control of germinating seedling weeds. Dry weather 
following a postemergence application of F4044-2 may reduce effectiveness. Rainfall or irrigation of at least ½ 
inch within 7 days should be received to ensure good control. F4044-2 may not control weeds that germinate 
after application but before an activating rainfall/irrigation has occurred or weeds that germinate through cracks 
resulting from dry soil. For layby applications to control late emerging weeds, apply to the soil before weed 
emergence or in combination with other herbicides or cultivation to control emerged weeds. For best results, 
direct the application to the soil below the corn canopy. 
 
Sequential applications 
F4044-2 can be applied in sequential programs, but do not exceed the maximum use rate per year. Where weeds 
are emerged use appropriate tank-mixtures for control of the weed species present. 
 
 F4044-2 may be used following an earlier application of F4044-2 herbicide during the same cropping season. 
 
Spray Equipment/Volume: Apply F4044-2 in sufficient water volume to ensure thorough coverage as a 
broadcast application for good weed control. 
 
For ground application, use a minimum of 10 gallons of spray solution per acre by ground sprayer. For 
aerial application, use aircraft spray equipment set to a minimum of 2 gallons of spray solution per acre for 
corn, cotton, and soybean. 
 
Application Method Restrictions 
Do not use flood irrigation to apply, activate or incorporate this product. 
 
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 F4044-2 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 F4044-2 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.

[Optional text appears in brackets] 
 
16 
 
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. 
 
x Do not apply sprayer cleaning solutions or rinsate to sensitive crops. 
 
x Do not store the sprayer overnight or for any extended period of time with F4044-2 spray solution 
remaining in the tank, spray lines, spray boom plumbing, spray nozzles or strainers. 
 
x If the sprayer has been stored or idle, purge the spray boom and nozzles with clean water before 
beginning any application. 
 
x Should small quantities of F4044-2 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. FMC accepts no liability for any effects due to inadequately cleaned 
equipment. 
 
When F4044-2 has been tank-mixed refer to the label of the product used previously or tank-mixed with F4044-2 
for any additional cleaning instructions. 
 
Handling 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. 
 
Additional State imposed requirements regarding well-head setbacks and operational area containment must be 
observed. 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. 
 
CROP USE DIRECTIONS 
 
CORN (FIELD CORN, SWEET CORN, POPCORN GROWN FOR GRAIN, SEED OR SILAGE USES) – CROP 
SECTION 
 
Preplant Surface or Preplant Incorporated Applications (up to 30 days prior to planting): Apply F4044-2 
as a broadcast or banded spray to the soil surface or incorporated up to 30 days before planting.

[Optional text appears in brackets] 
 
17 
Preemergence Surface Application: Apply F4044-2 as a broadcast or banded spray to the soil surface after 
planting and before crop emergence. 
 
Postemergence: F4044-2 does not have postemergence activi ty against weeds. F4044-2 can be applied 
postemergence from seedling emergence until the corn re aches 40 inches in height. Directed spray may 
be used to minimize interference from the crop and to increase soil coverage. Drop nozzles will provide 
optimum spray coverage and minimize contact with the crop when corn height is greater than 24 inches 
tall. 
 
Fall Application for Spring Weed Control: Apply after September 30 in ND, SD, MN, WI, and north of 
Route 30 in IA. Apply after October 15 north of Route 91 in NE and south of Route 30 in IA. Apply after 
October 31 north of Route 136 in IL. 
 
Application considerations for use of F4044-2 in corn: 
x For residual control of weeds only. 
x For heavy weed pressure and/or longer residual activity, use the higher la beled rate according to 
soil texture. 
x For control of emerged weeds, tank-mix with labe led postemergence herbicides plus any required 
adjuvants. 
x Rainfall or irrigation is required for incorporation and activation of F4044-2, or poor control of new 
weed flushes may result. 
x Corn seed must be planted a minimum of 1.5 inches deep. Shallow planting can lead to increased crop 
response risk. 
x A preplant or preemergence tank-mix followed by a sequential application of a postemergence herbicide 
may be necessary for some weeds. 
x Rainfall or irrigation is required for incorporation and activation of F4044-2, or poor control of new 
weed flushes may result. 
x For control of additional weed species, F4044-2 may be used in combination with other labeled corn 
herbicides for increased weed control. 
 
Application restrictions for use of F4044-2 in corn: 
x May only be applied to corn up to 40 inches in height. 
x Do not make more than 2 applications of F4044-2 per year. 
x Do not retreat within 14 days of application. 
x Do not apply more than 3 pt (1.5 lb ai/acre) total of F4044-2 per application. 
x Do not apply more than 3 pt (1.5 lb ai/acre) total of F4044-2 per cropping year.

COTTON - CROP SECTION 
 
Preplant Surface or Preplant Incorporated Applications (up to 30 days prior to planting): Apply F4044-2 
as a broadcast or banded spray to the soil surface or incorporated up to 30 days before planting. 
 
Preemergence Surface Application: Apply F4044-2 as a broadcast or banded spray to the soil surface after 
planting and before crop emergence. 
 
Postemergence: F4044-2 does not have postemergence activity against weeds. F4044-2 may be applied 
postemergence either as over the top or directed post emergence to cotton for residual preemergence control of 
listed weeds. F4044-2 must not be applied over-the-top when cotton is greater than 8 leaves. 
 
Postemergence-Directed – Early and Lay-by Applications: F4044-2 does not have postemergence 
activity against weeds. Apply F4044-2 alone or as a tank mixture with other herbicides residual 
preemergence control of listed weeds. 
 
Application considerations for use of F4044-2 in cotton: 
x For residual control of weeds only. 
x For heavy weed pressure and/or longer residual ac tivity, use the higher labeled rate according to 
soil texture. 
x For control of emerged weeds, tank-mix with labeled postemergence herbicides plus any required 
adjuvants. 
x Rainfall or irrigation is required for incorporation and activation of F4044-2, or poor control of new 
weed flushes may result. 
x A preplant or preemergence tank-mix followed by a sequential application of a postemergence herbicide 
may be necessary for some weeds. 
x Rainfall or irrigation is required for incorporation and activation of F4044-2, or poor control of new 
weed flushes may result. 
x For control of additional weed species, F4044-2 may be used in combination with other labeled cotton 
herbicides for increased weed control. 
 
Application restrictions for use of F4044-2 in cotton: 
x May only be applied to cotton up to first bloom. 
x Do not make more than 2 applications of F4044-2 per season. 
x Do not retreat within 14 days of application. 
x Do not apply more than 3 pt (1.5 lb ai/acre) total of F4044-2 per application. 
x Do not apply more than 3 pt (1.5 lb a.i./acre) total of F4044-2 per cropping season.

SOYBEAN - CROP SECTION 
 
Fall Application for Spring Weed Control: Apply after September 30 in ND, SD, MN, WI, and north of 
Route 30 in IA. Apply after October 15 north of Route 91 in NE and south of Route 30 in IA. Apply after 
October 31 north of Route 136 in IL. 
 
Preplant Surface or Preplant Incorporated Applications (up to 30 days prior to planting): Apply F4044-2 
as a broadcast or banded spray to the soil surface or incorporated up to 30 days before planting. 
 
Preemergence Surface Application: Apply F4044-2 as a broadcast or banded spray to the soil surface after 
planting and before crop emergence. For additional control of morningglory, common ragweed, Palmer amaranth 
and giant ragweed, velvetleaf, sunflower and others, use tank-mixes or sequential applications of AUTHORITY 
herbicides at their labeled use rate. 
 
Postemergence: F4044-2 does not have postemergence activity against weeds. F4044-2 may be applied 
postemergence for residual preemergence control of listed weeds. F4044-2 can be applied to soybeans from 
emergence to R1 stage. 
 
Application considerations for use of F4044-2 in soybean: 
x For residual control of weeds only. 
x For heavy weed pressure and/or longer residual ac tivity, use the higher la beled rate according to 
soil texture. 
x For control of emerged weeds, tank-mix with labe led postemergence herbicides plus any required 
adjuvants. 
x Rainfall or irrigation is required for incorporation and activation of F4044-2, or poor control of new 
weed flushes may result. 
x Soybean seed must be planted a minimum of ½ -inch deep. Shallow planting can lead to increased crop 
response risk. 
x A preplant or preemergence tank-mix followed by a sequential application of a postemergence herbicide 
may be necessary for some weeds. 
x Rainfall or irrigation is required for incorporation and activation of F4044-2, or poor control of new 
weed flushes may result. 
x For control of additional weed species, F4044-2 may be used in combination with other labeled soybean 
herbicides for increased weed control.
