HARMONY® GT XP herbicide, referred to below as HARMONY GT XP herbicide must be used only in accordance with 
instructions on this label or as otherwise permitted by FIFRA. Always read the entire label, including the Limitation of 
Warranty and Liability. 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.
HARMONY GT XP herbicide is for use on wheat, barley, oat, triticale, fallow, corn, soybeans and as a pre-plant and/or 
post-harvest burndown herbicide in most states. Check with your state extension service or Department of Agriculture before 
use, to be certain HARMONY GT XP herbicide is registered in your state.
PRODUCT INFORMATION
HARMONY GT XP herbicide may be used for selective post emergence control of certain broadleaf weeds in wheat 
(including durum), barley, oat, triticale, post-harvest burndown, pre-plant burndown, fallow, corn and soybeans. 
HARMONY GT XP herbicide is a dry flowable granule to be mixed in water or other listed carrier and applied as a uniform 
broadcast spray. It is noncorrosive, nonflammable, nonvolatile and does not freeze.
ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY
Best results are obtained when HARMONY GT 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 of control and duration of effect are 
dependent on rate used, sensitivity and size of target weed and environmental conditions at the time of and following
application.
HARMONY GT XP herbicide stops growth of susceptible weeds rapidly. However, typical symptoms of dying weeds 
(discoloration) may not be noticeable for 1-3 weeks after application (2-5 weeks for wild garlic) depending on the 
environmental conditions and weed susceptibility. Warm, moist conditions following treatment promote the activity of 
HARMONY GT XP herbicide, while cold, dry conditions delay the activity. Weeds hardened-off by cold weather or 
drought stress will be less susceptible.
A vigorous growing crop will aid weed control by shading and providing competition for weeds. However, a dense crop 
canopy at time of application can intercept spray and resu lt in reduced weed control. Weeds may not be adequately 
controlled in areas of thin crop stand or seeding skips.
Applications made to weeds that are in the cotyledon stage, larger than the size indicated, or to weeds under stress may 
result in unsatisfactory control.
HARMONY GT XP herbicide may injure crops that are stressed from adverse environmental conditions (including 
extreme temperatures or moisture), abnormal soil conditions, or cultural practices. In addition, different varieties of the 
crop may have differing levels of sensitivity to treatment with HARMONY GT XP herbicide under otherwise normal 
conditions. Treatment of sensitive crop varieties may injure crops.
Weed control may be reduced if rainfall or snowfall occurs soon after application. Several hours of dry weather are needed 
to allow HARMONY GT XP herbicide to be sufficiently absorbed by weed foliage.
To reduce the potential of crop injury in cereals, tank mix HARMONY GT XP herbicide with 2,4-D (ester formulations 
perform best–see the "TANK MIXTURES" section of this label) and apply after the crop is in the tillering stage of growth.
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 the tank mixture. If the 
instructions on the tank mix partner label conflicts with this HARMONY GT XP herbicide label, do not use in a tank 
mixture with HARMONY GT XP herbicide.

RESTRICTIONS
Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the following:
• Do not apply or drain or flush equipment on or near desirable trees or other plants, or on areas where their roots extend, or in
locations where the product may be washed or moved into contact with their roots.
• Do not use on lawns, walks, driveways, or tennis courts.
• Do notallow spraysto drift to desirableplants
• Do not apply to wheat, barley oats or triticale underseeded with another crop.
• Do not apply this product through any type of irrigationsystem.
• Do not apply by air in the State of NewYork.
• Do not apply after planting sorghum or rice.
• Do not apply later than 7 days before plantingcotton.
• Do not allow livestock to graze on, or feed forage, hay or straw from treated soybean fields.
• Do not graze or feed forage or grain from treated field corn to livestock within 30 days of application.
• Do not make more than one pre-plant or at-planting application of HARMONY GT XP herbicide to field corn, rice, 
sorghum, or soybeans per year
• Do not apply HARMONY GT XP herbicide to crops that are stressed by severe weather conditions, drought (including low
levels of subsoil moisture), low fertility, water-saturated soil, disease, or insect damage, as crop injury may result. Risk of
injury is greatest to cereals when the 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.
PRECAUTIONS
- Calibrate sprayers only with clean water away from the well site.
- Make scheduled checks of spray equipment.
- Assure accurate measurement of pesticides by all operationemployees.
- Mix only enough product for the job at hand.
- Avoid over-filling of spray tank.
- Dilute and agitate excess solution and apply at labeledrates/uses.
- Avoid storage of pesticides near well sites.
- When triple rinsing the pesticide container, be sure to add the rinsate to the spray mix.
- Take all necessary precautions to avoid all direct or indirect contact (including spray drift) with non-target plants or areas.
- Carefully observeall sprayercleanup instructions both priorto andafterusingthis product,asspraytank residue may damage 
crops other than wheat, barley, oats, triticale, corn or soybeans.
- For ground applications applied when dry, dusty field conditions exist, control of weeds in wheel track areas may be reduced. 
Soybeans, corn, and cereal varieties 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 of HARMONY GT XP herbicide to a small area.
- For cereals under certain conditions including heavy rainfall, prolonged cold weather (daily high temperature less than 50
Deg. F.), or wide fluctuations in day/night temperatures prior to or soon after HARMONY GT XP herbicide application, 
temporary discoloration and/or crop injury may occur. To reduce the potential of crop injury, tank mix HARMONY GT XP 
herbicide with 2,4-D (ester formulations perform best– see the "TANK MIXTURES IN CEREALS" section of this label) 
and apply after the crop is in the tillering stage ofgrowth.
- 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.

WEED RESISTANCE MANAGEMENT
HARMONY GT XP herbicide, which contains the active ingredient Thifensulfuron 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, follow as many of the following 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 relatively small (less than 4inches).
• Apply full rates of HARMONY GT XP herbicide for the most difficult to control weed in the field at the specified time 
(correct weed size) to minimize weedescapes.
• 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 determine 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 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 theseindicators:
- 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 ofaction.
• Rotate the use of this product with non-Group 2herbicides.
• Avoid making more than two applications of HARMONY GT 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 co ntrol 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 seedproduction.
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 dama ge. 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 GT XP herbicide can be tank mixed with “Axial” herbicides (Axial® Bold, Axial® Star, Axial® XL) for improved 
control of weeds in spring wheat. For postemergence applications, apply to young, actively growing weeds after crop emergence. 
Typically, small weeds (less than 1” in height or diameter) th at are actively growing at application are most easily controlled .
Refer to the specific product labels for information regarding use restrictions, labeled crops, rotational cropping intervals, sprayer 
cleanup, use precautions and other information. The most restrictive provisions will apply. Do not use the tank mix if any 
restrictions on the specific product labels conflict with the instructions on the FMC herbicide label.
With Other Grass Control Products
HARMONY GT XP herbicide can be tank mixed with grass control products. Antagonism generally does not occur. However, 
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 us e of 
HARMONY GT XP herbicide and the grass product to a small area.
With Fungicides
HARMONY GT XP herbicide may be tank mixed or used sequentially with fungicides registered for use on listed cereal grains.
With Insecticides
HARMONY GT XP herbicide may be tank mixed or used sequentially with insecticides registered for use on listed cereal grains. 
However, under certain conditions (drought stress, cold weather, or if the crop is in the 2-4 leaf stage), tank mixes or sequen tial 
applications of HARMONY GT XP herbicide with products containing organophosphate insecticides may produce temporary 
crop yellowing or, in severe cases, crop injury. The potential for crop injury is greatest when wide fluctuations in day/night
temperatures occur just prior to or soon after application. Test these mixtures in a small area before treating large areas.

13
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 mixin g 
HARMONY GT XP herbicide in fertilizer solution. HARMONY GT 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 GT 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 soluti on (less than 50% of the spray solution volume), the addition o f 
surfactant is necessary. Add surfactant at 1/2 pint -1 quart per 100 gal of spray solution (0.06 -0.25% v/v) based on local guidance. 
When using high rates of liquid nitrogen fertilizer in the spray solution, adding surfactant increases the risk of crop injury. Consult 
your agricultural dealer, consultant, fieldsman, or FMC representative for specific instructions before adding an adjuvant to t hese 
tank mixtures.
If 2,4-D or MCPA is included with HARMONY GT XP herbicide and the fertilizer mixture, ester formulations tend to be more 
compatible (See manufacturer’s label). Additional surfactant may not be needed when using HARMONY GT XP herbicide in 
tank mix with 2,4-D ester or MCPA ester and liquid nitrogen fertilizer solutions. Consult your agricultural dealer, consultant, field 
advisor, or FMC representative for specific instructions before adding an adjuvant to these tank mixtures.
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 fertilize r carrier 
solutions. Liquid nitrogen fertilizer solutions that contain sulfur can increase crop response.
SPECIFIC WEED RESTRICTIONS:
¾ Do notapplyHARMONY GT XP herbicidewithin60 daysof cropemergencewherean organophosphateinsecticidehas been
applied as an in-furrowtreatmentbecausecrop injury may result.
¾ Do not use HARMONY GT XP herbicide plus "Malathion" because crop injury will result.
¾ Do not use low rates of liquid fertilizer as a substitute for a surfactant.
¾ Do not use with liquid fertilizer solutions with a pH less than 3.0.

SOYBEANS
APPLICATION TIMING (POST EMERGENCE)
HARMONY GT XP herbicide may be applied to soybeans any time after the first trifoliate has expanded fully. Apply no later than 60 
days before harvest.
Early-season soybean injury may result from tank-mix applications with other registered herbicides. Injury may manifest itself as stunting 
(seen as a reduction in leaf size or internode length), yellowin g leaves and/or red veins, and necrosis in the leaves and petio les. The 
potential for soybean injury is most pronounced with applications made during hot, humid conditions, under widely fluctuating weather 
or temperature conditions, or with applications to soybeans under stress.
USE RATES IN SOYBEANS
Make a single application of HARMONY GT XP herbicide at a rate of 0.083 ounce per acre (0.0039 lb. ai/A) for selective postemergence 
broadleaf weed control on conventional soybean varieties.
HARMONY GT XP herbicide at up to 0.33 ounce per acre (0.0155 lb. ai/A) may be used on soybeans designated 
"STS"(Sulfonylurea Tolerant). Severe injury or death of soybeans will result if any soybeans not designated as "STS" (Sulfonylurea 
Tolerant) are treated with more than 0.083 ounce of HARMONY GT XP herbicide(0.0039 lb. ai/A). Multiple applications of
HARMONY GT XP herbicide may be applied to Sulfonylurea Tolerant (STS) soybeans provided no more than a total of 0.33 ounce
(0.0155 lb. ai/A) is applied per year.
SPRAY ADDITIVES
Applications of HARMONY GT XP herbicide in soybeans must include a nonionic surfactant or crop oil concentrate, and an ammonium 
nitrogen fertilizer. See SPRAY ADJUVANTS.
WEEDS CONTROLLED
When applied to soybeans as directed, HARMONY GT XP herbicide will control the following weeds
Weeds Controlled Maximum size (inches) at

TANK MIXTURES IN SOYBEANS
HARMONY GT XP herbicide may be tank mixed with full or reduced rates of other products registered for use in soybeans. However, 
FMC will not warrant crop safety or weed control of HARMONY GT XP herbicide tank mixtures with any other pesticide or spray 
adjuvant except as specified in this label or other FMC supplemental labeling or technical bulletins.
Restriction:
Do not tank mix HARMONY GT XP herbicide with organophosphate insecticides, or apply HARMONY GT XP 
herbicide within 14 days before or after an application of an organophosphate insecticide, as severe crop injury may 
occur.
With Postemergence Grass Herbicides
HARMONY GT XP herbicide may be tank mixed with postemergence grass herbicides including Assure® II herbicide.
With postemergence grass herbicides, use surfactant rate (concentration) of 1-2 pints per 100 gallons of spray solution 
(0.125%- 0.25% v/v concentration). Use of a higher rate of nonionic surfactant, particularly under hot, humid conditions, may 
result in temporary crop injury. Do not use crop oil concentrate when tank mixing HARMONY GT XP herbicide with 
postemergence grass herbicides unless specified on other FMC supplemental labeling. Include a nonionic surfactant with the 
tank mix of HARMONY GT XP herbicide and post grass herbicides including Assure II herbicide.
With Pursuit® herbicide for postemerge broadleaf weed control in soybeans for use in the State of North Dakota 
This tank mix is labeled for the control of broadleaf weeds only. Use different control measures to control grassy weeds,
including an application of Assure II herbicide 1 day before or 7 days after applying HARMONY GT XP herbicide
plus Pursuit herbicide. Conversely, a soil applied preemerge grass herbicide may be used in a planned weed control 
program with HARMONY GT XP herbicide plus Pursuit herbicide.
Apply a tank mix of 0.083 ounce per acre (0.0039 lb. ai/A) of HARMONY GT XP herbicide plus Pursuit herbicide at
labeled rates for postemerge control of the broadleaf weeds listed in the table below. Best results are obtained when the 
HARMONY GT XP herbicide plus Pursuit herbicide tank mix is applied to weeds that are young (after the first true
leaves have expanded, but before they exceed the size indicated in the table below) and actively growing. Applications 
made to weeds that are in the cotyledon stage, larger than the size indicated below, or to weeds under stress (weather, 
herbicide, or other) may result in unsatisfactory control.

Apply after the first trifoliate of the soybean plant has fully expanded. Applications of HARMONY GT XP herbicide plus Pursuit
herbicide tank mixes must be made before soybeans have begun to flower. Maintain an interval of at least 85 days between an application 
of Pursuit herbicide and soybean harvest.
Apply to soybeans that are free from stress and are actively growing. Stress may be caused by abnormally hot or cold weather, growing 
conditions including drought or water-saturated soil, disease, soil nutrient deficiencies including iron chlorosis, or injury from nematodes, 
insects, or prior herbicide applications.
Applications of HARMONY GT XP herbicide plus Pursuit herbicide may shorten stem internodal length and cause temporary crop 
injury. Crop response may be increased when applications are made to soybeans that are under stress.

ADJUVANTS
Post emerge applications of HARMONY GT XP herbicide tank mixed with Pursuit herbicide m ust include the addition of a 
nonionic surfactant and ammonium nitrogen fertilizer.
• A nonionic surfactant must be included at the rate of 1 pint per 100 gallons of solution (0.125% v/v concentration).Do not use 
crop oil concentrates or methylated seed oil products.
• Useahigh qualityliquidnitrogenfertilizerincluding28-0-0,or10-34-0 at labeled rates. Use the lower rate for spray volumes less
than 15 gallons per acre. Alternately, a high-quality, sprayable grade of ammoniumsulfate (21-0-0) may be used atlabeled rates.
Broadcast Application: Use flat fan nozzles at 25-60 psi. Do not use flood, hollow cone, rain drop, whirl chamber or controlled 
droplet applicator (CDA) type nozzles as unacceptable crop injury, excessive spray drift, or poor weed control may result. Use 10- 25 
gallons of water per acre. For proper spray coverage, adjust the boom and nozzle height according to the specifications listed by the 
nozzle manufacturer.
Band Application: For band application, use proportionately less spray mixture. To avoid crop injury, carefully calibrate the band 
applicator not to exceed the labeled rate. Carefully follow the manufacturer's instructions for nozzle types (flat fan nozzles 
preferred),nozzleorientation,distanceof nozzlesfromthe cropand weeds,sprayvolumes,calibration,and spraypressure.
AerialApplication:Usenozzletypesandarrangementsthatwillprovideforoptimumspraydistributionandmaximumcoverageat 5 
to 10 GPA.Do not apply during a temperature inversion condition, when winds are gusty, or when other conditions will favor poor 
coverage and/or off target spray movement. Use a minimum of 5 gallons of water per acre. Consult the respective product labels 
for specialdirectionsfor aerialapplication.
ROTATIONAL CROP GUIDELINES
Soybeans, field corn, grain sorghum, rice, safflower, wheat, barley, oats, and triticale may be planted anytime after the application of 
HARMONY GT XP herbicide. Cotton may be planted 7 days after application. Any other crop may be planted 45 days after the 
application of HARMONY GT XP herbicide. Refer to the Pursuit herbicide labels for guidelines on planting rotational crops following 
its use. Follow the maximum time interval listed on the respective labels prior to planting a rotational crop. The most restrictive time 
interval shall apply.

17
RESTRICTIONS 
Refer to the Pursuit herbicide label for additional use directions, use restrictions, and precautions. The most restrictive 
provision on either the Pursuit herbicide label, or this HARMONY GT XP herbicide label will apply.
x Do not allow spray from either ground or aerial equipment to drift onto adjacent crops or land, as injury 
to other plants may occur.
x Do not tank mix with organophosphate insecticides, or apply within 14 days before or after an application 
of an organophosphate insecticide as severe crop injury may occur.
x Do not graze animals on green forage or stubble. Do not utilize hay or straw for animal feed or bedding.
PRECAUTIONS
Sequential applications of HARMONY GT XP herbicide following post emerge Pursuit herbicide treatments are not advised 
because:
x Crop injury from sequential post emerge applications of HARMONY GT XP herbicide following Pursuit herbicide 
is greater than from the use of either product applied alone. The first application interferes with the soybean plant's 
ability to metabolize the second herbicide treatment. Sequential applications may result in severe crop injury.
x Any weeds not controlled by the Pursuit herbicide application will be stressed at the time of the sequential treatment. 
This will result in unsatisfactory weed control, particularly for stress sensitive weeds including lambsquarters.
x Weeds that have recovered from a Pursuit herbicide application will typically be larger than labeled size by the time 
soybeans may be safely treated with a HARMONY GT XP herbicide application. This will result in unsatisfactory 
weed control.
HARMONY GT XP herbicide plus Pursuit herbicide treatments may be tank mixed with Assure II herbicide to control 
volunteer corn and shattercane. Pursuit herbicide will reduce the activity of Assure II herbicide on all other grasses. For 
broad spectrum grass control, apply Assure II herbicide 1 day before, or 7 days after Pursuit herbicide treatments. Refer to 
the Assure II herbicide label for application rates, weed sizes, and restrictions.
Applications within 1 hour of rain may reduce weed control.
Cultivation before, during, or within 7 days after the application may put the weeds under stress by pruning roots. Root 
pruning may reduce weed control. The best time to cultivate is approximately 14 days after application.
To avoid subsequent injury to crops other than soybeans, thoroughly clean all mixing and spray equipment immediately 
following application.
Refer to the respective labels for cleanout procedures. Follow the more restrictive cleanout directions.

PRECAUTIONS
• Apply to soybeans that are free from stress and are actively growing . Stress may be caused by abnormally hot or coldweather,
growingconditionsincludingdroughtorwater-saturatedsoil,disease,soilnutrientdeficienciesincludingiron chlorosis, orinjury
from nematodes,insects,or priorherbicideapplications.
• Applications of HARMONY GT XP herbicide when tank mixed with Pursuit herbicide may shorten stem internodal length and
cause temporary crop injury. Crop response may be increased when applications are made to soybeans that are under stress. 
Soybeans will recover quickly under normalgrowing conditions.
• Cultivation may put weeds under stress by pruning roots, thus reducing weed control. Avoid cultivation 7-10 days prior to or 
followingapplicationoftheherbicidetreatment.Formaximumweedcontrol,cultivate7-10daysafterapplication.
• Apply this treatment after the first trifoliate of the soybean has fully expanded and the plants are actively growing, but before 
soybeansbegintoflower.
• Refer to the HARMONY GT XP herbicide or Pursuit herbicide labels for additional use directions, use restrictions, rotational
crop intervals, and precautions. The most restrictive provision on either label willapply.
• Applications within1 hour ofrain may reduce weedcontrol.
With Glyphosate
HARMONY GT XP herbicide may be tank mixed with glyphosate for control of certain broadleaf weeds in Roundup Ready or 
Roundup Ready X "STS (Sulfonylurea Tolerant) stacked trait" soybeans. For tank mixtures of HARMONY GT XP herbicide plus 
glyphosate herbicide, always read and follow all use directions, restrictions, and pre-cautions on the EPA approved labels. When 
tank mixing, the most restrictive labeling applies.
For improved control of common lambsquarters, volunteer “Roundup Ready” canola, ALS-sensitive horseweed and kochia, and/or

AT THE END OF THE DAY
During periods when multiple loads of HARMONY GT XP herbicide are applied, at the end of each day of spraying, rinse the 
interior of the tank with fresh water and then partially fill, and flushthe boom and hoses. This will prevent the buildup of dried 
pesticide deposits which can accumulate in the application equipment.
AFTER SPRAYING HARMONY GT XP herbicide AND BEFORE SPRAYING CROPS OTHER THAN 
WHEAT, BARLEY, OAT, TRITICALE, FIELD CORN AND SOYBEANS
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately following 
applications of HARMONY GT XP 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 ingredient) 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-stre ngth ammonia solution or an FMC-approved clea ner 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 because dangerous gases will form. Do not clean equipment in an 
enclosed area.
2. Steam-clean aerial spray tanks prior to performing the above cleanout procedure to facilitate the removal of any caked
deposits.
3. When HARMONY GT XP herbicide is tank mixed with other pesticides, examine all cleanout procedures for each product

MANDATORY SPRAY DRIFT MANAGEMENT
Ground Boom Applications:
• Apply with the nozzle height advised by the manufacturer, but no more than 3 feet above the ground or crop canopy,
unless making a turf, pasture, or rangeland application, in which case applicators may apply with a nozzle height no 
more than 4 feet above the ground.
• 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.
Boom-less Ground Applications:
• Applicators are required to use a Medium or coarser droplet size (ASABE S572.1) for all applications.
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• Do not apply during temperature inversions.
SPRAY DRIFT MANAGEMENT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT.
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While 
applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly o r 
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 advised 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 directions for setting up nozzles. Generally, to reduce fine droplets, orient 
nozzles 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, 
keep the boom level with the crop and minimizebounce.
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.

25
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.
BOOM-LESS GROUND APPLICATIONS
Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read and 
carefully observe cautionary statements and all other information on the additive’s label. If using an additive that increases 
viscosity, ensure that the nozzles and other application equipment will function properly with a viscous spray solution. Preferred 
drift control additives have been certified by the Council of Producers & Distributors of Agrotechnology CPDA).
