ENVIRONMENTAL HAZARDS
Do not apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water 
mark. Do not contaminate water by cleaning of equipment or disposing of equipment washwaters or wastes.
Groundwater Advisory
This product has properties and characteristics associated with chemicals detected in groundwater. This product may leach into
groundwater 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 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 weeks or more
after application. A level, well-maintained vegetative buffer strip between areas to which this product is applied and surface water
features such as ponds, streams, and springs will reduce the potential loading of this product from runoff water and sediment. Runoff of
this product will be greatly reduced by avoiding applications when rainfall or irrigation is expected to occur within 48 hours.
Windblown Soil Particles$GYLVRU\
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion usually have a high silt and/or
fine to very fine sand fractions and low organic matter content. Other factors which can affect the movement of windblown soil include
the intensity and direction of prevailing winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product 
ifprevailing local conditions may be expected to result in off-site movement.
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 area. Protect the forage and habitat of non-target organisms by minimizing spray drift. For further guidance and
instructions on how to minimize spray drift, refer to the Spray Drift Management section of this label.

HARMONY® EXTRA herbicide must be used only in accordance with directions on this label.
HARMONY® EXTRA herbicide is directed for use on wheat, barley, oat, and fallow in most states, check with 
your state extension or Dept. of Agriculture before use, to be certain HARMONY® EXTRA herbicide is registered 
in your state.
To the extent consistent with applicable law, FMC will not be responsible for losses or damages resulting from the 
use of this product in any manner not specifically directed by FMC.
PRODUCT INFORMATION
HARMONY® EXTRA herbicide is a dry flowable granule that is used for selective postemergence weed control in 
wheat (including durum), barley, oat and fallow. The best control is obtained when HARMONY® EXTRA 
herbicide is applied to young, actively growing weeds. The use rate will depend on weed spectrum and size of weed 
at time of application. The degree and duration of control may depend on the following:
• weed spectrum and infestation intensity
• weed size at application
• environmental conditions at and following treatment
HARMONY® EXTRA herbicide is noncorrosive, nonflammable, nonvolatile, and does not freeze. 
HARMONY® EXTRA herbicide must be mixed in water and applied as a uniform broadcast spray.
RESTRICTIONS
Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the 
following:
• DO NOT apply, drain or flush equipment on or near desirable trees or other plants or on areas where their roots 
may extend, or in locations where the chemical may be washed or moved into contact with their roots.
• DO NOT use on lawns, walks, driveways, tennis courts, or similar areas. Prevent drift of spray to desirable plants.
DO NOT apply to wheat, barley or oat crops underseeded with another crop.
DO NOT harvest sooner than 45 days after the last application of HARMONY® EXTRA herbicide.
PRECAUTIONS
Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the 
following:
• Take all necessary precautions to avoid all direct or indirect contact (including spray drift) with non-target plants 
or areas.
Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue 
may damage crops other than wheat, barley or oat.
Dry, dusty field conditions may result in reduced control in wheel track areas.
Varieties of wheat (including durum) and barley may differ in their response to various herbicides. Consult
your state experiment station, university, or extension agent as to sensitivity to any herbicide. If no information is 
available, limit the initial use to a small area.
Under certain conditions including heavy rainfall, prolonged cold weather, or wide fluctuations in day/night
temperatures prior to or soon after HARMONY® EXTRA application, temporary discoloration and/or crop injury 
may occur. To reduce the potential of crop injury, tank mix HARMONY® EXTRA with 2,4-D (ester formulations 
perform best–see Tank Mixtures) and apply after the crop is in the tillering stage of growth.
HARMONY® EXTRA must not be applied to wheat, barley or oat that is stressed by severe weather conditions, 
drought, low fertility, water saturated soil, disease, or insect damage, as crop injury may result. Risk of injury is 
greatest when crop is in the 2 to 5- leaf stage. Severe winter stress, drought, disease, or insect damage following 
application also may result in crop injury.

ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY
HARMONY® EXTRA herbicide is absorbed primarily through the foliage of plants, rapidly inhibiting the growth 
of susceptible weeds. One to 3 weeks after application to weeds (2 to 5 weeks for wild garlic), leaves of susceptible 
plants appear chlorotic, and the growing point subsequently dies.
HARMONY® EXTRA herbicide provides the best control in vigorously growing crops that shade competitive 
weeds. Weed control in areas of thin crop stand or seeding skips may not be as satisfactory. However, a crop canopy 
that is too dense at application can intercept spray and reduce weed control.
The herbicidal action of HARMONY® EXTRA herbicide may be affected in crops stressed from adverse 
environmental conditions (including extreme temperatures or moisture), abnormal soil conditions, cultural practices, 
or variations in crop variety. In warm, moist conditions, the expression of herbicide symptoms is accelerated; in 
cold, dry conditions, expression of herbicide symptoms is delayed. In addition, weeds hardened-off by drought stress 
are less susceptible to HARMONY® EXTRA herbicide.

With other grass control products
Tank mixtures of HARMONY® EXTRA herbicide and grass control products may result in poor grass control. 
Consult your state experiment station, university, or extension agent, Agricultural dealer, or FMC representative as 
to the potential for antagonism before using the mixture. If no information is available, limit the initial use of 
HARMONY® EXTRA herbicide and the grass product to a small area.
With Insecticides
HARMONY® EXTRA herbicide may be tank mixed or used sequentially with insecticides (or fungicides) 
registered for use on cereal grains. However, under certain conditions (drought stress, or if the crop is in the 2-4 leaf 
stage), tank mixes or sequential applications of HARMONY® EXTRA herbicide with organophosphate insecticides 
may produce temporary crop yellowing or, in severe cases, crop injury. Test these mixtures in a small area before 
treating large areas.
DO NOT use HARMONY® EXTRA herbicide plus products containing malathion, as crop injury will result.
With Liquid Nitrogen Solution Fertilizer
Liquid nitrogen fertilizer solutions may be used as a carrier in place of water. Run a tank mix compatibility test 
before mixing HARMONY® EXTRA herbicide in fertilizer solution. HARMONY® EXTRA herbicide must first be 
slurried with water and then added to liquid nitrogen solutions (e.g., 28-0-0, 32-0-0). Ensure that the agitator is 
running while the HARMONY® EXTRA herbicide is added. Use of this mixture may result in temporary crop 
yellowing and stunting.
If using low rates of liquid nitrogen fertilizer in the spray solution (less than 50% of the spray solution volume), the 
addition of surfactant is necessary. Add surfactant at 1/4 qt - 1 qt per 100 gal of spray solution (0.06 -0.25% v/v) 
based on local directions.
When using high rates of liquid nitrogen fertilizer solution in the spray solution, adding surfactant increases the risk 
of crop injury. Consult your agricultural dealer, consultant, fieldman, or FMC representative for specifications
before adding an adjuvant to these tank mixtures.
If 2,4-D or MCPA is included with HARMONY® EXTRA herbicide and fertilizer mixture, ester formulations tend 
to be more compatible (See manufacturer’s label). Additional surfactant is not needed when using HARMONY® 
EXTRA herbicide in tank mix with 2,4-D ester or MCPA ester and liquid nitrogen fertilizer solutions.
DO NOT use low rates of liquid nitrogen fertilizer solution as a substitute for a surfactant.
DO NOT use with liquid fertilizer solutions with a pH less than 3.0.
CROP ROTATION
Wheat, Barley, and Oat may be replanted anytime after the application of HARMONY® EXTRA herbicide.
Sugarbeets, Winter Rape, and Canola can be planted 60 days after the application of HARMONY® EXTRA 
herbicide. Any other crop may be planted 45 days after the appli cation of HARMONY® EXTRA herbicide.
APPLICATION INFORMATION
Since HARMONY® EXTRA herbicide has very little or no soil activity, it controls only those weeds that have 
germinated; therefore, apply HARMONY® EXTRA herbicide when all or most of the weeds have germinated. 
Annual broadleaf weeds must be past the cotyledon stage, actively growing, and less than 4” tall or wide. Wild 
garlic plants must be less than 12” tall with 2” to 4” of new growth. See Specific Weed Problems for more 
information.
Rainfall immediately after treatment can wash HARMONY® EXTRA herbicide off of weed foliage, resulting in 
reduced weed control. Several hours of dry weather are needed to allow HARMONY® EXTRA herbicide to be 
sufficiently absorbed by weed foliage.

specified rate of HARMONY® EXTRA herbicide per acre and include a tank mix partner such as 2,4-D, MCPA, dicamba or
bromoxynil containing herbicides (refer to TANK MIXTURES).
SPECIFIC WEED PROBLEMS
Canada thistle: For control in wheat and barley, use 0.6 oz/A HARMONY® EXTRA herbicide plus surfactant 
when all thistles are 4” to 8” with 2” to 6” of new growth. Make the application in the spring. Control will be 
improved by using HARMONY® EXTRA herbicide in combination with 2,4-D (refer to TANK MIXTURES).
For control in oat, use 0.4 oz/A HARMONY® EXTRA herbicide plus 2,4-D (refer to TANK MIXTURES).
Common cocklebur, Common ragweed, Lanceleaf sage: In wheat and barley, apply HARMONY® EXTRA 
herbicide at 0.4 to 0.5 oz/A in combination with 2,4-D at rates from 1/4 to 3/8 lb active ingredient (ester 
formulations work best) per acre when weeds are small and actively growing. When using 1/4 lb active ingredient of 
2,4-D per acre, be sure to add surfactant at the rate of 1/4 to 1/2 quart per 100 gallons of spray solution (0.06 to 
0.125% v/v—use the higher rate under stress conditions).
For control in oat, use 0.4 oz/A HARMONY® EXTRA herbicide plus 2,4-D. Refer to the Tank Mixtures sections of 
this label for additional details.

14 
 
Corn gromwell, Wild buckwheat: For control in wheat and barley, use 0.5 to 0.6 oz/A HARMONY® EXTRA 
herbicide plus surfactant.
For control in oat, use 0.4 oz/A HARMONY® EXTRA herbicide plus 2,4-D, MCPA or bromoxynil containing 
herbicides (refer to TANK MIXTURES).
Kochia, Russian thistle, Prickly lettuce: Naturally occurring resistant biotypes of these weeds are known to occur. 
For best results, use HARMONY® EXTRA herbicide in a tank mix with dicamba and 2, 4-D; or bromoxynil and 
2,4-D. Apply HARMONY® EXTRA herbicide in the spring when weeds are less than 2” tall or 2” across and are 
actively growing. Refer to the Tank Mixtures section of this label for additional details.
Vetch (common and hairy): For control in wheat and barley, use 0.5 to 0.6 oz/A of HARMONY® EXTRA 
herbicide plus surfactant when vetch is less than 6” in length. For severe infestations of vetch, or when vetch is 
greater than 6” in length, use HARMONY® EXTRA herbicide in combination with 2,4-D or MCPA (refer to the 
Tank Mixtures section of this label).
For control in oat, use 0.4 oz/A HARMONY® EXTRA herbicide plus 2,4-D or MCPA (refer to TANK 
MIXTURES).
Wild garlic: For control in wheat and barley, use 0.5 to 0.6 oz/A HARMONY® EXTRA herbicide plus surfactant 
when wild garlic plants are less than 12” tall with 2” to 4” of new growth. For severe infestations, use the 0.6 oz/A
rate of HARMONY® EXTRA herbicide. Plants hardened-off by cold weather and/or drought stress may be more 
difficult to control. Thorough spray coverage of all garlic plants is essential. Typical symptoms of dying garlic 
plants may not be noticeable for 2 to 5 weeks.
For control in oat, use 0.4 oz/A HARMONY® EXTRA herbicide plus 2,4-D or MCPA (refer to TANK 
MIXTURES).
Wild radish: For best results in wheat and barley, apply 0.4 to 0.6 oz/A HARMONY® EXTRA herbicide plus 
surfactant either in the fall or spring to wild radish rosettes less than 6 inches in diameter. Applications made later 
than 30 days after weed emergence will result in partial control. For increased control of severe wild radish 
infestations, or wild radish emerged greater than 30 days, apply HARMONY® EXTRA herbicide at 0.3 oz/A in 
combination with MCPA at 1/4 lb active ingredient per acre. Surfactant is required when tank mixing with MCPA, 
add 1 quart per 100 gallons of spray solution (0.25% vol/vol). Fall applications must be made prior to hardening off 
of plants.
For control in oat, use 0.4 oz/A HARMONY® EXTRA herbicide plus 2,4-D or MCPA (refer to TANK 
MIXTURES).
SURFACTANTS
Unless otherwise specified, add an FMC advised nonionic surfactant having at least 80% active ingredient at 1 to 2 
qt per 100 gal of spray solution (0.25 to 0.5% v/v - refer to TANK MIXTURES for specific adjuvant directions
when HARMONY® EXTRA herbicide is used in a tank mix).
Consult your agricultural dealer, applicator, or FMC representative for a listing of advised surfactants. Antifoaming 
agents may be used if needed.
DO NOT use low rates of liquid nitrogen fertilizer solution as a substitute for surfactant.
GROUND APPLICATION
For optimum spray distribution and thorough coverage, use flat-fan or low-volume flood nozzles.
For flat-fan nozzles, use a spray volume of at least 5 gal per acre (GPA).
For flood nozzles on 30” spacings, use at least 10 GPA, flood nozzles no larger than TK10 (or the equivalent), and a 
pressure of at least 30 psi. For 40” nozzle spacings, use at least 13 GPA; for 60” spacings use at least 20 GPA. It is 
essential to overlap the nozzles 100% for all spacings.

15 
 
Raindrop “RA” nozzles are not advised for HARMONY® EXTRA herbicide applications, as weed control 
performance may be reduced.
Use screens that are 50-mesh or larger.
Chemigation - Refer to specific supplemental labeling for use directions for HARMONY® EXTRA herbicide in 
chemigation systems.
DO NOT apply this product through any irrigation system unless the supplemental labeling on chemigation is 
followed.
AERIAL APPLICATION
Use nozzle types and arrangements that provide optimum spray distribution and maximum coverage at 2 to 5 GPA. 
Use at least 3 GPA in Idaho, Oregon, or Utah.
DO NOT apply HARMONY® EXTRA herbicide by air in the state of New York. See the Spray Drift Management 
section of this label.
PRODUCT MEASUREMENT
HARMONY® EXTRA herbicide is measured using the HARMONY® EXTRA h erbicide volumetric measuring 
cylinder. The degree of accuracy of this cylinder varies by ± 7.5%. For more precise measurement, use scales
calibrated in ounces.
PESTICIDE HANDLING
• Calibrate sprayers only with clean water away from the well site.
• Make scheduled checks of spray equipment.
• Ensure that all operation employees accurately measure pesticides.
• Mix only enough product for the job at hand.
• Avoid overfilling of spray tank.
• DO NOT discharge excess material on the soil at a single spot in the field, grove, or mixing/loading station.
• Dilute and agitate excess solution and apply at labeled rates or uses.
• Avoid storage of pesticides near well sites.
• When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix.
MIXING INSTRUCTIONS
1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of HARMONY® EXTRA herbicide
3. Continue agitation until the HARMONY® EXTRA herbicide is fully dispersed, at least 5 minutes.
4. Once the HARMONY® EXTRA herbicide is fully dispersed, maintain agitation and continue filling tank with 
water. HARMONY® EXTRA herbicide must be thoroughly mixed with water before adding any other material.
5. As the tank is filling, add tank mix partners (if desired) then add the required volume of nonionic surfactant. 
Always add surfactant last. DO NOT use with spray additives that alter the pH of the spray solution below pH 5.0 
or above pH 9.0, as rapid product degradation can occur. Spray solutions of pH 6.0-8.0 allow for optimum
stability of HARMONY® EXTRA herbicide.
6. If the mixture is not continuously agitated, settling will occur. If settling occurs, thoroughly re-agitate before 
using.
7. Apply HARMONY® EXTRA herbicide spray mixture within 24 hours of mixing to avoid product degradation.
8. If HARMONY® EXTRA herbicide and a tank mix partner are to be applied in multiple loads, pre-slurry the
HARMONY® EXTRA herbicide in clean water prior to adding to the tank. This will prevent the tank mix partner 
from interfering with the dissolution of the HARMONY® EXTRA herbicide.

16 
 
GRAZING
DO NOT graze livestock in treated areas. In addition, DO NOT feed forage or hay from treated areas to livestock 
(harvested straw may be used for bedding and/or feed).
SPRAY EQUIPMENT
SPRAYER CLEANUP
The spray equipment must be cleaned before HARMONY® EXTRA herbicide is sprayed. Follow the cleanup 
procedures specified on the labels of the previously applied products. If no directions are provided, follow the six 
steps outlined in After Spraying HARMONY® EXTRA herbicide.
AT THE END OF THE DAY
FMC advises that during periods when multiple loads of HARMONY® EXTRA herbicide are applied, at the end of 
each day of spraying the interior of the tank be rinsed with fresh water and then partially filled, and the boom and 
hoses flushed. This will prevent the buildup of dried pesticide deposits which can accumulate in the application 
equipment.
AFTER SPRAYING HARMONY® EXTRA HERBICIDE AND BEFORE SPRAYING 
CROPS OTHER THAN WHEAT, BARLEY AND OAT
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately 
following applications of HARMONY® EXTRA herbicide as follows:
1. Drain tank; thoroughly rinse spray tanks, boom, and hoses with clean water. Loosen and physically remove any
visible deposits.
2. Fill the tank with clean water and 1 gal of household ammonia* (contains 3% active) for every 100 gal of water. 
Flush the hoses, boom, and nozzles with the cleaning solution. Then add more water to completely fill the tank. 
Circulate the cleaning solution through the tank and hoses for at least 15 min. Flush the hoses, boom, and nozzles
again with the cleaning solution, and then drain the tank.
3. Remove the nozzles and screens and clean separately in a bucket containing cleaning agent and water.
4. Repeat step 2.
5. Rinse the tank, boom, and hoses with clean water.
6. If only Ammonia is used as a cleaner, the rinsate solution may be applied back to the crop(s) specified on this 
label. DO NOT exceed the maximum labeled use rate. If other cleaners are used, consult the cleaner label for
rinsate disposal instructions. If no instructions are given, dispose of the rinsate on site or at an approved waste
disposal facility.
* Equivalent amounts of an alternate-strength ammonia solution or an FMC-approved cleaner can be used in the cleanout 
procedure. Carefully read and follow the individual cleaner instructions. Consult your Ag dealer, applicator, or FMC 
representative for a listing of approved cleaners.
Notes:
1. CAUTION: DO NOT use chlorine bleach with ammonia as dangerous gases will form. DO NOT clean
equipment in an enclosed area.
2. Steam-clean the aerial spray tanks prior to performing the above cleanout procedure to facilitate the removal of
any caked deposits.
3. When HARMONY® EXTRA herbicide is tank mixed with other pesticides, all cleanout procedures must be
examined and the most rigorous procedure must be followed.
4. In addition to this cleanout procedure, all precleanout guidelines on subsequently applied products must be
followed as per the individual labels.
5. Where routine spraying practices include shared equipment frequently being switched between applications of
HARMONY® EXTRA herbicide and applications of other pesticides to HARMONY® EXTRA herbicide-
sensitive crops during the same spray season, dedicate a sprayer to HARMONY® EXTRA herbicide to further
reduce the chance of crop injury.

MANDATORY SPRAY DRIFT
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.
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 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).
• The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade diameter for
helicopters.
• Applicators must use 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 CONDITION S.
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.

18 
 
RELEASE HEIGHT - Aircraft
Higher release heights increase the potential for spray drift. When applying aerially to crops, DO NOT release spray 
at a height greater than 10 ft above the crop canopy, unless a greater application height is necessary for pilot safety.
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 Chemical Producers and 
Distributors Association (CPDA).
WEED RESISTANCE MANAGEMENT
HARMONY® EXTRA herbicide, which contains the active ingredients Thifensulfuron methyl and Tribenuron 
methyl, is a group 2 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.

19 
 
• Control weeds early when they are relatively small (less than 4 inches).
• Apply full rates of HARMONY® EXTRA 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 these
MOAs have been found in your region. DO NOT assume that each listed weed is being controlled by multiple sites 
of action. Products with multiple active ingredients are intended to broaden the spectrum of weeds that are
controlled.
Some weeds may be controlled by only one of the active ingredient in this product.
• If resistance is suspected, treat weed escapes with an herbicide having a site of action other than Group 2 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 2 herbicides.
• Avoid making more than two applications of HARMONY® EXTRA herbicide and any other Group 2 herbicides 
within a single year 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, such as mechanical cultivation, crop rotation, cover crops and 
weed-free crop seeds, as part of an integrated weed control program.
• Use good agronomic principles that enhance crop development and crop competitiveness.
• Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds.
• Manage weeds in and around fields, during and after harvest to reduce weed seed production.
INTEGRATED PEST MANAGEMENT
This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, 
cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field 
scouting or other detection methods, correct target pest identification, population monitoring, and treating when 
target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, 
professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for
treating specific pest/crop systems in your area.
