USER SAFETY RECOMMENDATIONS
USERS SHOULD: Users should remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly 
and put on clean clothing”. “Users should 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.
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 when cleaning equipment or disposing of equip ment washwaters or 
rinsate.
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 Advisory
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 if prevailing 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.
PRODUCT INFORMATION
HARMONY® EXTRA XP herbicide is a dry flowable granule that is used for selective postemergence weed 
control in wheat (including durum), barley, oat, triticale and fallow. The best control is obtained when HARMONY 
EXTRA XP 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 XP herbicide is noncorrosive, nonflammable, nonvolatile, and does not freeze. HARMONY 
EXTRA XP herbicide must be mixed in water and applied as a uniform broadcast spray.

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, triticale or oat.
Dry, dusty field conditions may result in reduced control in wheel track areas.
Varieties of wheat (including durum), barley and triticale may differ in their response to various herbicides. FMC
advises that you first 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 XP herbicide a pplication, temporary discoloration and/or 
crop injury may occur. To reduce the potential of crop injury, tank mix HARMONY EXTRA XP herbicide 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 XP herbicide cannot be applied to wheat, barley. triticale 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 XP 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 XP 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 XP 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 XP herbicide.
WEED RESISTANCE MANAGEMENT
HARMONY EXTRA XP 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.
• Control weeds early when they are relatively small (less than 4 inches).

5 
 
• Apply full rates of HARMONY EXTRA XP 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 XP herbicide and any other Group 2 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.
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.

HARMONY EXTRA XP herbicide may be used as a 
burndown treatment to wheat (including durum), barley, 
triticale and oat to control emerged weeds prior to, or 
shortly after planting (prior to emergence). Make 
applications when the majority of weeds have emerged and 
are actively growing. HARMONY EXTRA XP herbicide 
can also be used as a burndown treatment prior to planting 
other crops including rice, soybeans, corn, grain sorghum, 
sugarbeets, winter rape, canola, and cotton. See “CROP 
ROTATION” before planting other crops.
Apply 0.3 to 0.6 oz/A HARMONY EXTRA XP herbicide 
as a burndown treatment before planting all crops except 
cotton.
Apply 0.3 to 0.5 oz/A HARMONY EXTRA XP herbicide 
as a burndown treatment before planting cotton. Allow at 
least 14 days between application of HARMONY EXTRA 
XP herbicide and planting of cotton. Include a nonionic 
surfactant, petroleum based crop oil concentrate, or 
vegetable-seed oil-based product (methylated seed oils are 
considered a vegetable seed-based oil). If another herbicide 
is tank mixed with HARMONY EXTRA XP herbicide to 
increase the broadleaf weed spectrum, select adjuvants 
based on the adjuvant limitations of the companion 
herbicide.
Cotton Precaution: Seedling disease, nematodes, cold 
weather, deep planting (more than 2”), excessive moisture, 
high salt concentration, and/or drought may weaken cotton 
seedlings and increase the possibility of crop injury. Cotton 
resumes normal growth once favorable growing conditions 
return.
HARMONY EXTRA XP herbicide may be applied alone 
or in combination with other suitable registered burndown 
herbicides (see TANK MIXTURES - PRE-PLANT 
BURNDOWN).
Use the higher end of the rate range when weed infestation 
is heavy or predominantly consists of those weeds listed 
under PARTIAL CONTROL or when application timing 
and environmental conditions are marginal.
Sequential treatments of HARMONY EXTRA XP
herbicide may be made provided the total amount of 
HARMONY EXTRA XP herbicide applied does not exceed 
1.0 oz/A per year.

APPLICATION TIMING
Cereals:
In Wheat (Including Durum), Barley, Winter Oat and Triticale, make applications after the crop is in the 2-leaf 
stage, but before the flag leaf is visible.
In Spring Oat, make applications after the crop is in the 3 leaf stage, but before jointing. DO NOT use on "Ogle", 
"Porter" or "Premier" varieties as crop injury can occur.
Since HARMONY EXTRA XP herbicide has very little or no soil activity, it controls only those weeds that have 
germinated; therefore, apply HARMONY EXTRA XP 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 XP herbicide off of weed foliage, resulting in 
reduced weed control. Several hours of dry weather are needed to allow HARMONY EXTRA XP herbicide to be 
sufficiently absorbed by weed foliage.
Fallow:
HARMONY EXTRA XP herbicide may be used as a fallow treatment, in the spring or fall when the majority of 
weeds have emerged and are actively growing.
Pre-Plant Burndown:
HARMONY EXTRA XP herbicide may be used as a burndown treatment to wheat (including durum), barley, 
triticale and oat to control emerged weeds prior to, or shortly after planting (prior to emergence). Make applications 
when the majority of weeds have emerged and are actively growing. HARMONY EXTRA XP herbicide can also be 
used as a burndown treatment prior to planting other crops including soybeans, corn, and cotton. See “CROP 
ROTATION” for the minimum time interval required before planting other crops.
SURFACTANTS
Unless otherwise specified, add an FMC specified 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 XP herbicide is used in a tank mix).
For pre-plant burndown in Cotton, include a nonionic surfactant, petroleum based crop oil concentrate, or a 
vegetable-seed oil-based product (methylated seed oils are considered a vegetable seed-based oil). If another 
herbicide is tank mixed with HARMONY EXTRA XP herbicide to incre ase the broadleaf weed spectrum, select 
adjuvants based on the adjuvant limitations of the companion herbicide.
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.

Canada thistle*
Carolina geranium
Catchweed bedstraw
Cutleaf eveningprimrose
Mallow (common, little)
Nightshade (cutleaf, hairy)
Vetch* (common, hairy)
* See SPECIFIC WEED PROBLEMS for more information.
**Partial Control: A visual reduction of weed population as well as a significant loss of vigor. For best results, use the highest labeled rate of
HARMONY EXTRA XP herbicide per acre and include a tank mix partner including 2,4-D, MCPA, Buctril® herbicide or Banvel®
herbicide/Clarity® herbicide (refer to TANK MIXTURES).
SPECIFIC WEED PROBLEMS
Canada thistle: For control in wheat, barley and triticale, use 0.6 oz/A HARMONY EXTRA XP 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 XP herbicide in combination with 2,4-D.
For control in oat, use 0.4 oz/A HARMONY EXTRA XP herbicide plus 2,4-D.
Common cocklebur, Common ragweed, Lanceleaf sage: In wheat, barley and triticale, apply HARMONY 
EXTRA XP 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) when weeds are small and actively growing. When using 1/4 lb active ingredient of 2,4-D, 
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 XP herbicide plus 2,4-D.
Corn gromwell, Wild buckwheat: For control in wheat, barley and triticale, use 0.5 to 0.6 oz/A HARMONY 
EXTRA XP herbicide plus surfactant.
For control in oat, use 0.4 oz/A HARMONY EXTRA XP herbicide plus 2,4-D, MCPA or Buctril® Herbicide.

14 
 
Kochia, Russian thistle, Prickly lettuce: Naturally occurring resistant biotypes of these weeds are known to occur. 
For best results, use HARMONY EXTRA XP herbicide in a tank mix with dicamba and 2,4-D; or Bromoxynil 
(including Buctril® Herbicide) and 2,4-D (3/4 - 1 pt Buctril® Herbicide + 1/4 - 3/8 lb active ingredient 2, 4-D
ester). HARMONY EXTRA XP herbicide needs to be applied in the spring when weeds are less than 2” tall or 2” 
across and are actively growing.
Vetch (common and hairy): For control in wheat, barley and triticale, use 0.5 to 0.6 oz/A HARMONY EXTRA XP
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 XP herbicide in combination with 2,4-D or MCPA.
For control in oat, use 0.4 oz/A HARMONY EXTRA XP herbicide plus 2,4-D or MCPA.
Wild garlic: For control in wheat, barley and triticale, use 0.5 to 0.6 oz/A HARMONY EXTRA XP herbicide plus 
surfactant when wild garlic plants are less than 12” tall with 2” to 4” of new growth. For severe infestations, use 0.6 
oz/A HARMONY EXTRA XP 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 XP herbicide plus 2,4-D or MCPA.
Wild radish: For best results in wheat, barley and triticale, apply 0.4 to 0.6 oz/A HARMONY EXTRA XP
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 XP
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 need to be 
made prior to hardening off of plants.
For control in oat, use 0.4 oz/A HARMONY EXTRA XP herbicide plus 2,4-D or MCPA.

products for a greater spectrum of broadleaf control. Refer to the Puma® 1EC herbicide label for information 
regarding use restrictions, labeled crops, rotational cropping intervals, sprayer cleanup, use precautions and other 
information. The most restrictive provisions on either label will apply. DO NOT use the tank mix if any restrictions 
on the Puma® 1EC herbicide label conflict with the instructions on the FMC herbicide label.
With other grass control products
Tank mixtures of HARMONY EXTRA XP herbicide and grass control products may result in poor grass control. 
FMC advises that you first 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 XP herbicide and the grass product to a small area.
With Insecticides
HARMONY EXTRA XP 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 XP herbicide with organophosphate 
insecticides (including parathion) 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 XP 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 XP herbicide in fertilizer solution. HARMONY EXTRA XP 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 XP 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 guidance.
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 specific instructions 
before adding an adjuvant to these tank mixtures.
If 2,4-D or MCPA is included with HARMONY EXTRA XP herbicide and fertilizer mixture, ester formulations 
tend to be more compatible (See manufacturer’s label). Additional surfactant is not needed when using HARMONY 
EXTRA XP herbicide in tank mix with 2,4-D ester or MCPA ester and liquid nitrogen fertilizer solutions.
Note: In certain areas east of the Mississippi river unacceptable crop response may occur with use of straight or 
dilute nitrogen fertilizer carrier solutions where cold temperatures or widely fluctuating day/night temperatures 
exist. In these areas consult your agricultural dealer, consultant, field advisor, or FMC representative for specific 
instructions before using nitrogen fertilizer carrier solutions.
Liquid nitrogen fertilizer solutions that contain sulfur can increase crop response.

18 
 
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.
GRAZING
Allow at least 7 days between application and grazing of treated forage. In addition, allow at least 7 days between 
application and feeding of forage from treated areas to livestock. Allow at least 30 days between application and 
feeding of hay from treated areas to livestock. Harvested straw may be used for bedding and/or feed. Allow at least
45 days between application and harvesting of grain.

PRODUCT APPLICATION INFORMATION
PRODUCT MEASUREMENT
HARMONY EXTRA XP herbicide is measured using the HARMONY EXTRA XP herbicide 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 XP herbicide.
3. Continue agitation until the HARMONY EXTRA XP herbicide is fully dispersed, at least 5 minutes.
4.Once the HARMONY EXTRA XP herbicide is fully dispersed, maintain agitation and continue filling tank with 
water. HARMONY EXTRA XP herbicide must be thoroughly mixed with water before adding any other material.

19 
 
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 XP herbicide.
6. If the mixture is not continuously agitated, settling will occur. If settling occurs, thoroughly re-agitate before 
using.
7. Apply HARMONY EXTRA XP herbicide spray mixture within 24 hours of mixing to avoid product degradation.
8. If HARMONY EXTRA XP herbicide and a tank mix partner are to be applied in multiple loads, pre-slurry the 
HARMONY EXTRA XP 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 XP herbicide.
APPLICATION METHOD
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.
“Raindrop RA” nozzles are not advised for HARMONY EXTRA XP herbicide applications, as weed control 
performance may be reduced.
Use screens that are 50-mesh or larger.
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 XP herbicide by air in the state of New York.

and Bronate® herbicide package labels for a list of weeds controlled/suppressed.
SPRINKLER IRRIGATION APPLICATION
Apply this tank mix through sprinkler irrigation systems including center pivot, lateral move, side (wheel) roll, solid 
set or hand move irrigation systems only. DO NOT apply these herbicides through any other type of irrigation 
system.
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniform distribution
of treated water. If you have questions about calibration, you may contact State Extension Service specialists, 
equipment manufacturers or other experts. DO NOT connect an irrigation system (including greenhouse 
systems) used for HARMONY EXTRA XP herbicide application to any public water system. 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 if the need arises.

20 
 
The sprinkler chemigation system must contain a functional check valve, vacuum relief valve, and low pressure 
drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow. The 
pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of 
fluid back toward the injection pump. The pesticide injection pipeline must also contain a functional, normally 
closed, solenoid- operated valve located on the intake side of the injection pump and connected to the system 
interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either 
automatically or manually shut down. The system must contain functional interlocking controls to automatically 
shut off the pesticide injection pump when the water pump motor stops. The irrigation line or water pump must 
include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the 
point where pesticide distribution is adversely affected. Systems must use a metering pump, including a positive 
displacement injection pump (e.g., diaphragm pump), effectively designed and constructed of materials that are
compatible with pesticides and capable of being fitted with a system interlock. DO NOT apply when wind speed 
favors drift beyond the area intended for treatment.
SPECIFIC REQUIREMENTS FOR APPLICATION THROUGH SPRINKLER IRRIGATION SYSTEMS
1. In center pivot and continuous lateral move systems, HARMONY EXTRA XP herbicide + Bronate® herbicide
needs to be applied continuously for the duration of the water application. In solid set systems, application of the 
tank mix needs to be made during the last 30 to 45 minutes of the irrigation set.
2. Set the sprinkler system to deliver approximately 0.5 inch or less of water per acre for best product performance.
3. Fill the supply tank with half of the water amount desired, add the HARMONY EXTRA XP herbicide and agitate
it well. Add the Bronate® herbicide and then add the remaining water amount with agitation. Bronate® herbicide
requires a dilution with at least 4 parts water to 1 part Bronate® herbicide.
4. Agitation is advised in the pesticide supply tank when applying this tank mix.
5. The use of a surfactant is not advised with this tank mix application.
6. Inject the HARMONY EXTRA XP herbicide + Bronate® herbicide solution at least 8 feet ahead of a right angle 
turn of irrigation pipe to insure adequate mixing. Allow sufficient time for the herbicide mixture to be flushed 
through the lines before turning off irrigation water.
7. Follow both HARMONY EXTRA XP herbicide and Bronate® herbicide label instructions for spray tank cleanout 
both before and after application. Flush lines with clean water following application.
8. DO NOT apply when wind speed favors drift beyond the area intended for treatment. Avoiding spray drift is the
responsibility of the applicator.
SPRAY EQUIPMENT
Be sure to calibrate air or ground equipment properly before application. Select a spray volume and delivery system 
that will ensure thorough coverage and a uniform spray pattern with minimum drift. Use higher spray volumes to 
obtain better coverage when crop canopy is dense. Avoid swath overlapping, and shut off spray booms while 
starting, turning, slowing, or stopping, to avoid injury to the crop.
Continuous agitation is required to keep HARMONY EXTRA XP herbicide in suspension.
Before Spraying HARMONY EXTRA XP HERBICIDE
The spray equipment must be cleaned before HARMONY EXTRA XP 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 XP herbicide.
At the End of the Day
It is advised that during periods when multiple loads of HARMONY EXTRA XP 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.

21 
 
After Spraying HARMONY EXTRA XP HERBICIDE and Before Spraying Crops
Other Than Wheat, Barley, Triticale and Oat
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately 
following applications of HARMONY EXTRA XP herbicide as follows:
1. Drain tank; thoroughly rinse spray tanks, boom, and hoses wit h 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 buck et 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 ma y be applied back to the crop(s) advised 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-cleaning aerial spray tanks is advised prior to performing the above cleanout procedure to facilitate the 
removal of any caked deposits.
3.When HARMONY EXTRA XP 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 XP herbicide and applications of other pesticides to HARMONY EXTRA XP herbicide-
sensitive crops during the same spray season, it is advised that a sprayer be dedicated to HARMONY EXTRA XP
herbicide to further reduce the chance of crop injury.

MANDATORY SPRAY DRIFT MANAGEMENT
Ground Boom Applications:
• Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or crop
canopy.
• For applications prior to the emergence of crops and target weeds, applicators are required to use a Coarse or 
coarser droplet size (ASABE S572.1).
• For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE S572.1).
• DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
• DO NOT apply during temperature inversions.
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.
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.

23 
 
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).
