APPLICATION INFORMATION - ALL USES 
o SYNCHRONY® XP (mp) herbicide is a dispersible 
granule formulation which readily dissolves in water. 
o SYNCHRONY® XP (mp) may be used in conventional, 
no-till, or conservation tillage soybean production. 
Timing To Crop Stage 
SYNCHRONY® XP (mp), for in-season use, may he 
applied any time after the fIrst trifoliate has opened but no 
later than 60 days hefore soybean maturity. 
2 
o SYNCHRONY® XP (mp), for bumdown use, may he 
applied up to 30 days hefore planting, or prior to soyhean 
emergence after planting. 
Timing To Weeds 
Apply SYNCHRONY® XP (mp) when weeds are young and 
actively growing (after the fIrst true leaves have expanded, 
but hefore the weeds exceed the size indicated helow). 
o Applications made to weeds larger than the sizes indicated 
below. or to weeds under stress, may result in unsatisfactory 
control. 
o Applications made after July 15 may result in less than 
satisfactory weed control due to the large sizes of the weeds 
and increased weather stress. 
Tank Mix Restrictions 
When tank mixing SYNCHRONY® XP (mp) with any other 
approved soyhean pesticide, always read and follow all use 
directions, restrictions and precautions of both SYNCHRONY® 
XP (mp) and the tank mix partner(s). When tank mixing, the 
most restrictive laheling applies. 
Weed control and crop safety resulting from the use of 
tank mixtures not specifically noted on this lahel, or in 
separately published DuPont recommendations, are the 
responsibility of the user. 
Cultivation 
Do not cultivate within 7 days of application. Cultivation 
may put weeds under stress by pruning roots, thus 
diminishing control. 
Cultivation approximately 14 days after application will help 
control suppressed weeds. 
SYNCHRONY® XP (MP) AT 0.75 -1.125 
OZ PER ACRE - IN SEASON USE ON 
"STS" SOYBEANS ONLY 
FOR USE ONLY ON SOYBEAN VARIETIES 
DESIGNATED AS "STS" 
The normal use rate of SYNCHRONY® XP (mp) on 
STS soyheans is 0.75 oz oz per acre. 
SYNCHRONY® XP (mp) may be used at 1.125 oz per 
acre for preserving the STS trait in STS soybean seed 
production. Consult ROTATIONAL CROP 
GUIDEUNES for recrop intervals when using the 
1.125 oz application rate. 
o Application to soyhean varieties not designated as 
"STS" will result in severe crop injury andlor yield 
loss. 
o DuPont will not warrant the safety of this treatment to 
seed saved from previous year's production (bin run 
seed). 
o These "STS" varieties must be purchased from an 
authorized seed supplier. 
o The "STS" designation indicates the soybean variety 
contains a proprietary trait that enhances the 
soybean's natural tolerance to DuPont soybean 
sulfonylurea herbicides. Information on "STS" 
soybean varieties may he obtained from your seed 
supplier or DuPont representative.

following sequential applications. 
Spray Additives: 0.75 ozlacre rate in season 
Applications of SYNCHRONY® XP (MP) must include 
either a crop oil concentrate or a nonionic surfactant. Crop oil 
concentrate is the required adjuvant system unless tank 
mixing with a product that precludes use of crop oil 
concentrate. An ammonium nitrogen fertilizer may also be 
required. Products that combine ammonium fertilizers with 
surfactants or crop oils must meet all of the surfactant/crop oil 
and ammonium nitrogen fertilizer requirements. 
Consult local DuPont fact sheets, technical bulletins, and service 
policies prior to using other adjuvant systems. If another 
herbicide is tank ntixed with SYNCHRONY® XP (mp), select 
adjuvants authorized for use with both products. Adjuvants must 
contain only EPA-exempt ingredients (40 CFR 1001). 
Crop Oil ConcentraJe (COC) • Petroleum or Modified Seed Oil 
(MSO) 
- Apply at 1% vlv (I.gal per 100 gal spray solution) or 2% under 
arid conditions. 
-Oil adjuvants must contain at least 80% high quality, petroleum 
(mineral) or modified vegetable seed oil with at least 15% 
surfactant emulsifiers. 
Noninnic SurJacwnl (NIS) 
- Apply at 0.25% vlv (I qt per 100 gal spray solution) or 0.5% 
under arid conditions. 
- Surfactant pnoducts must contain at least 60% nonionic 
surfactant with a hydrophilic/lipophilic balance (HLB) greater 
than 12. 
Ammonium Nitrogen Fertilizer 
- Use 2 qt/acre of a high-quality urea ammonium nitrate (VAN), 
such as 28%N or 32%N, or 2 Ib/acre of a spray grade 
ammonium sulfate (AMS). Use 4 qt/acre UAN or 4 Iblacre 
AMS under arid conditions. 
• Do not use liquid nitrogen fertilizer as the total camer solution.

Specilll Adjuvant Types 
• Combination adjuvant products may be used at doses that 
provide the required amount of NIS, COC, MSO andlor 
ammonium nitrogen fertilizer. Consult product literature for use 
rates and restrictions. 
• In addition to the adjuvants specified above, other adjuvant 
types may be used if they provide the same functionality and 
have been evaluated and approved by DuPont Product 
Management. Consult separate DuPont technical bulletins for 
detailed information before using adjuvant types not specified

For control of Prickly 5ida and Hemp Seshanja tank mix 
075 oz SYNCHBONY® Xl' Imp) with 8- I 2 5 11 QZ 
"Cobra", 
Use the higher "Cobra" rate when Prickly Sida or Hemp Sesbania 
are heavy or if Prickly Sida and Hemp Sesbania approach the 
maximum size of I" or 4", respectively. Include a nonionic 
surfactant at 1-2 pt per 100 gallons of spray solution (.125-.25% 
v/v). Do not use crop oil concentrate when tankmixing 
SYNCHRONY® Xl' (mp) and "Cobra" at these rates. 
• Precautions for tankmixes of SYNCHRONY® Xl' (mp) 
plus "Flexstar", "Reflex", ''Blazer'', or "Cobra" 
Tank mix applications of SYNCHRONY® XP (mp) plus

results, apply SYNCHRONY® Xl' (mp) seven days before or 
one day after the grass herbicide. Refer to the grass herbicide 
label for precautions and specific use information. 
SYNCHRONY® XP (mp) and "FirstRate" herbicide: 
For improved Ragweed and Cocklebur control, add between 
0.075 - 0.3 oz per acre to 0.75 oz per acre SYNCHRONY® XP 
(mp). These tankmixes will control up to 10" Cocklebur or 
Common Ragweed and up to 12" Giant Ragweed. Use a lower 
amount of "FirstRate" when weeds are less than the maximum 
size and under good growing conditions. Use a higher amount of 
"FirstRate" when weeds are approaching the maximum size 
and/or under unfavorable growing conditions. 
A good quality petroleum-based or methylated seed oil-based 
crop oil concentrate must be added to the tank mix at the rate of 8 
pints per 100 gallons of spray solution or at 1% v/v. An 
ammonium nitrogen fertilizer may be added as directed under the 
"Spray Additives" section. 
SYNCHRONY® XP (mp) and 2,4-DB: 
• In soybeans at least 8" tall, 0.75 oz SYNCHRONY® Xl'

for improved control of giant ragweed up to 4" tal!, annual 
momingglory and other broadleaf weeds. 
• Applications ofSYNCHRONY® Xl' (mp) and 2,4-DB must 
include a nonionic surfactant at the rate of2 pints per 100 gal 
or crop oil concentrate at 8 pints per 100 gal of spray solution 
(1.0% v/v). See Spray Additives. 
• Apply a tank mix of SYNCHRONY® Xl' (mp) and 2,4-DB 
by ground only. 
• In Kansas and Missouri (except the bootheel area), when 
conditions are excessively hot and dry ( > 90"F and < 30% 
relative humidity), make applications at the rate of 2 fl oz of 
2,4-DB and SYNCHRONY® Xl' (mp).

• The use of crop oil concentrate may increase temporary 
injury to soybeans. 
Some crop response may occur 5-7 days after application of 
OuPont™ SYNCHRONY® XP (mp) and 2,4-0B to soybeans 
under stress. Temporary yellowing, leaf crinkling, and/or 
soybean growth retardation may occur following application of 
SYNCHRONY® XP (mp) and 2,4-0B. Under favorable 
growing conditions, the crop will quickly recover.

Precautions for 0.375 oz SYNCHRONY® XP (mp) uses 
• A temporary crop response may occur following an 
application of SYNCHRONY® XP (mp) to soybeans not 
designated "SIS" in the variety name. 
• Applications made when the crop and weeds are under stress 
from moisture. cold. heat, high humidity. disease. insect 
pressure and prior herbicide stress may result in excessive 
crop response and/or reduced weed control effectiveness. 
• Do not tankmix "Poast Plus" with 0.375 ozlacre 
SYNCHRONY® XP (mp) unless the soybean is designated 
as an "STS" variety. 
TANK MIX COMPATIBILITY TESTING 
Perform a jar test prior to tank mixing to ensure compatibility 
of SYNCHRONY® XP (mp) and other pesticides. Use a clear 
glass quart jar with lid and mix the tank mix ingredients in 
their relative proportions. Invert the jar containing the mixture 
several times and observe the mixture for approximately 1/2 
hour. If the mixture balls-up. forms flakes, sludges. gels, oily 
film or layers. or other precipitates. it is not compatible. 
MIXING INSTRUCTIONS 
I. Fill the tank 1/4 to 1/3 full of water. 
2. While agitating, add the required amount of SYNCHRONY® 
XP (mp). 
3. Continue adequate agitation. 
4. SYNCHRONY® XP (mp) should be thoroughly mixed 
with water in the spray tank before adding any other 
material. As the tank is filling. add (in order): other 
herbicide(s). the required spray adjuvant, and the nitrogen 
fertilizer where required. 
5. Apply SYNCHRONY® XP (mp) spray preparation within 24 
hours of mixing to avoid product degradation. 
6. If the mixture has settled. thoroughly reagitate before using. 
APPLICATION EQUIPMENT 
Ground Application 
(See Also Spray Drift Management) 
Broadcast Application 
• Postemergence in soybeans. use a minimum of 10 gal water 
per acre. Under heavy weed pressure or dense crop foliage. 
increase minimum spray volume to 15-25 gal per acre. 
• Use flat fan nozzles at 25-60 psi for SYNCHRONY® XP (mp) 
applications. 
• For bumdown applications of existing vegetation. flat fan 
nozzles and a minimum of 20 gallons per acre are 
recommended so as to thoroughly wet the foliage to be burned 
down. 
• Do not use flood, rain drop, whirl chamber. or controlled 
droplet applicator (CDA) type nozzles. Unacceptable crop 
injury, excessive spray drift, or poor weed control may result.

• For proper spray coverage adjust the boom and nozzle height 
according to the specifications listed by the nozzle 
manufacturer. 
Band Application 
• Because band applicators spray a narrower area than broadcast 
applicators, use proportionately less spray solution for band 
applications. 
• Carefully calibrate the band applicator to not exceed the 
labeled rate. 
• Flat fan nozzles are recommended. 
• Carefully follow the nozzle manufacturer's instructions for 
nozzle orientation, distance of the nozzles from the crop and 
weeds, spray volumes, calibration, and spray pressure for band 
applications. 
• For additional information on row banders, see DuPont 
bulletin, "Application Accuracy - Row Banders." 
Aerial Application 
(See Also Spray Drift Management) 
• Use nozzle types and arrangements that will provide optimum 
spray distribution and maximum coverage at 3-5 gal per acre. 
• Use a minimum of 3 gal water per acre. Under heavy weed 
pressure or dense crop foliage, increase the minimum spray 
volume to 5 gal per acre. 
• Do not apply during a temperature inversion, when winds are 
gusty. or when other conditions could produce poor coverage 
and/or off-target spray movement. 
ENVIRONMENTAL CONDITIONS 
AND BIOLOGICAL ACTIVITY 
DuPont™ SYNCHRONY® XP (mp) rapidly inhibits the growth 
of susceptible weeds. Leaves of susceptible plants yellow 3-5 
days after application, followed, in controlled plants, by the death 
of the growing point. SYNCHRONY® XP (mp) will provide 
complete control of susceptible weeds in 7-21 days. Suppressed 
plants may remain green but will be stunted and noncompetitive. 
SYNCHRONY® XP (mp) will provide best results when 
applied to young, actively growing weeds. Degree of control 
depends on: weed spectrum; weed size (if weeds are large, 
use higher spray volume); growing conditions at and 
following treatment; soil moisture; precipitation; and spray 
adjuvants. Treating weeds under stress or large weeds may 
result in only partial control. Stress may be caused by: 
• abnormal weather (hot or cold) 
• mechanical injury from cultivation 
• drought 
water-saturated soil 
• disease 
• insect injury 
• prior herbicide injury 
Stress affects some weeds, such as pigweed. more than others. 
Delay application until stress passes and weeds start to grow 
again. 
Severe stress (drought, disease, insect damage, or nutrient 
deficiency such as iron chlorosis) following application may also 
result in poor weed control. 
Do not apply SYNCHRONY® XP (mp) if rain is expected 
within 
1 hour or weed control may decrease.

ROTATIONAL CROP GUIDELINES 
Crop rotation intervals noted in the table below below are based 
on crops grown under favorable growing conditions. Crops 
grown under unfavorable environmental conditions. such as 
drought, nutrient deficiency, high salts, disease and insect 
pressure may demonstrate reduced tolerance to crop protection 
chemicals. When deciding on a particular crop to replant in your 
fields, carefully consider your particular soil and other field 
conditions (see IMPORTANCE OF SOIL pH section of this 
label). 
• Important: Crops other than soybeans following a 
SYNCHRONY® XP (mp) application can vary in their 
sensitivity to low concentrations of SYNCHRONY® XP (mp) 
remaining in the soil. Rotational crop guidelines must be 
followed. 
Region A: The states of Delaware, minois, Indiana, Iowa (fields 
located outside the boundaries of the Clarion-Nicollet-Webster 
and Hamburg-Ida-Monona soil associations and fields located 
outside the historic flood plain of the Missouri River), Kansas, 
Kentucky, Maryland, Michigan (fields south of Interstate 96 or 
per supplemental labeling), Missouri (except the Bootheel), 
Nebraska (fields south of Route 30 and east of Route 281), New 
Jersey, Ohio, Pennsylvania and West Virginia. 
Region B: The states of Alabama (except the "Black Belt" 
where soil pH must be less than 7.0), Arkansas, Florida, Georgia, 
Louisiana, Missouri (Bootheel region only), Mississippi (except

THE IMPORTANCE OF SOIL PH 
Soil pH varies greatly, even within the same field. pH variations 
as much as 2 pH units are common. Composite soil samples 
taken across an entire field, such as those samples taken for soil 
fertility recommendations, may not detect areas of high pH. Sulr 
sampling is recommended for areas likely to have pH values 
higher than the field average. The following is a non-inclusive 
list of potential high pH areas where subsampling is 
recommended. 
• Where different soil types are evident within a field, sample 
soil types separately. 
• Where conditions vary within a field, sample areas separately, 
such as: 
- areas bordered by limestone gravel roads, 
- river bottoms subject to flooding, 
- low areas in hardpan soils where evaporative ponds 
may occur. 
- eroded hillsides, 
- along drain tile lines, and 
- areas where drainage ditch spoil has been spread. 
• Where lime has not been deeply incorporated, soil may exhibit 
significantly higher pH values in the upper 3 inches of soil. 
Composite soil samples taken at a 6-8 inch depth may not 
reflect the elevated pH near the surface. In these cases shallow 
sampling, the upper 3 inches, is advised. 
Determine soil pH by laboratory analysis using a 1:1 soil:water 
suspension. 
SPRAYER PREPARATION AND CLEANUP 
Prior to application of SYNCHRONY® XP (mp), start with 
clean, well maintained application equipment. Immediately 
following application, thoroughly clean all application 
equipment. Postponing action, even for a few hours, only 
makes effective cleanup more difficult. Failure to clean 
spraying equipment thoroughly may result in injury to 
subsequently sprayed crops. 
When spraying multiple loads of SYNCHRONY® XP (mp) 
over an extended period of time, rinse the equipment with 
clean water at the end of the day. Leave water in the equipment 
overnight to prevent deposits from drying on surfaces. 
When applications of SYNCHRONY® XP (mp) are completed 
and prior to using the sprayer and associated equipment for 
other products or for crops other than soybeans, thoroughly 
clean the equipment using the procedure below. 
STEP I. Drain spray equipment. Thoroughly rinse sprayer, and 
flush hoses, boom and nozzles with clean water. 
Loosen and physically remove visible deposits. 
STEP 2. Fill the sprayer with clean water and add household 
ammonia (one gallon of 3% active for every 100 
gallons of water) or correct amount of a DuPont 
approved cleaner*. Flush hoses. boom and nozzles. 
Turn off the boom and top off the tank with clean 
water. Circulate through the spraying system for IS 
minutes. Flush the hoses, boom and nozzles with the 
cleaning solution. Drain the tank. 
STEP 3. Remove and clean nozzle, screens and strainers in a 
bucket of fresh cleaner and water. 
STEP 4. Repeat STEP 2.

STEP 5. Thoroughly rinse the sprayer, hoses, hnom and 
nozzles with clean water, several times. 
Clean all other associated application equipment. Take all 
necessary safety precautions when cleaning equipment. Do not 
clean near wells, water sources or near desirable vegetation. 
Dispose of waste rinse water in accordance with local 
regulations. 
• For additional information on sprayer cleanup and a listing of 
DuPont-approved cleaners, see DuPont Bulletin "A Guide 
To Application Equipment Cleanout For DuPont 
Sulfonylurea Herbicides". 
SPRAY DRIFT MANAGEMENT 
The interaction of many equipment and weather-related 
factors determines the potential for spray drift. The 
applicator is responsible for considering all these factors 
when making application decisions. 
AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY 
OF THE APPLICATOR. 
IMPORTANCE OF DROPLET SIZE 
The most effective way to reduce drift potential is to apply 
large droplets (>150 - 200 microns). The best drift 
management strategy is to apply the largest droplets that 
provide sufficient coverage and control. The presence of 
sensitive species nearby. the environmental conditions, and 
pest pressure may affect how an applicator balances drift 
control and coverage. APPLYING LARGER DROPLETS 
REDUCES DRIFT POTENTIAL, BUT WILL NOT 
PREVENT DRIFT IF APPLICATIONS ARE MADE 
IMPROPERLY OR UNDER UNFAVORABLE 
ENVIRONMENTAL CONDITIONS! See Wind, 
Temperalure and Humidily, and Temperalure Inversions 
sections of this label. 
Controlling Droplet Size - General Techniques 
• Volume - Use high flow rate nozzles to apply the highest 
practical spray volume. Nozzles with higher rated flows 
produce larger droplets. 
• Pressure - Use the lower spray pressures recommended 
for the nozzle. Higher pressure reduces droplet size and 
does not improve canopy penetration. WHEN IDGHER 
FLOW RATES ARE NEEDED, USE A IDGHER­
CAPACITY NOZZLE INSTEAD OF INCREASING 
PRESSURE. 
• Nozzle Type - Use a nozzle type that is designed for the 
intended application. With most nozzle types, narrower 
spray angles produce larger droplets. Consider using low­
drift nozzles. 
Controlling Droplet Size - Aircraft 
• Number of Nozzles - Use the minimum number of nozzles 
with the highest flow rate that provide uniform coverage. 
• Nozzle Orientation - Orienting nozzles so that the spray is 
emitted backwards, parallel to the airstream will produce 
larger droplets than other orientations. 
• Nozzle Type - Solid stream nozzles (such as disc and core 
with swirl plate removed) oriented straight back produce 
larger droplets than other nozzle types. 
• Boom Length - The boom length should not exceed 3/4 of 
the wing or rotor length - longer booms increase drift 
potential. 
• Application Heighl - Application more than 10 ft ahnve 
the canopy increases the potential for spray drift. 
9 
BOOM HEIGHT 
Setting the hnom at the lowest labeled height (if specified) 
which provides unifonn coverage reduces the exposure of 
droplets to evaporation and wind. For ground equipment, the 
boom should remain level with the crop and have minimal 
bounce. 
WIND 
Drift potential increases at wind speeds of less than 3 mph 
(due to inversion potential) or more than 10 mph. However, 
many factors, including droplet size and equipment type 
determine drift potential at any given wind speed. AVOID 
GUSTY OR WINDLESS CONDITIONS. 
Nole: Local terrain can influence wind patterns. Every 
applicator should be familiar with local wind patterns and 
how they affect spray drift. 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, set up 
equipment to produce larger droplets to reduce effects of 
evaporation. 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. 
Temperature inversions restrict vertical air mixing, which 
causes small suspended droplets to remain close to the 
ground and move laterally in a concentrated cloud. 
Temperature inversions are characterized by increasing 
temperature with altitude and are common on nights with 
limited cloud cover and light to no wind. They begin to form 
as the sun sets and often continue into the morning. Their 
presence can be indicated by ground fog; however, if fog is 
not present, inversions can also be identified by the 
movement of smoke from a ground source or an aircraft 
smoke generator. Smoke that layers and moves laterally in a 
concentrated cloud (under low wind conditions) indicates an 
inversion, while smoke that moves upward and rapidly 
dissipates indicates good vertical air mixing. 
SHIELDED SPRAYERS 
Shielding the boom or individual nozzles can reduce the 
effects of wind. However, it is the responsibility of the 
applicator to verify that the shields are preventing drift and 
not interfering with uniform deposition of the product. 
AIR ASSISTED (AIR BLASn 
FIELD CROP SPRAYERS 
Air assisted field crop sprayers carry droplets to the target via 
a downward directed air stream. Some may reduce the 
potential for drift, but if a sprayer is unsuitable for the 
application andlor set up improperly, high drift potential can 
result. It is the responsibility of the applicator to determine 
that a sprayer is suitable for the intended application, is 
configured properly, and that drift is not occurring. 
Nole: Air assisted field sprayers can affect product 
performance by affecting spray coverage and canopy 
penetration. Consult the application equipment section of 
this label to determine if use of an air assisted sprayer is 
recommended.

. , 
AIR ASSISTED (AIR BLAST) 
TREE AND VINE SPRAYERS 
Air assisted tree and vine sprayers carry droplets into the 
canopy of trees and vines via a radially or laterally directed 
air stream. These sprayers are not suitable for applying 
herbicides. 
IMPORTANT PRECAUTIONS 
Do not graze treated fields or harvest for forage or hay. 
Do not apply this product through aoy type of inigation 
equipment. 
Injury to or loss of desirable trees or vegetation may result from 
failure to observe the following: 
• Do not apply DuPont™ SYNCHRONY® XP (mp) or drain or 
flush equipment on or near desirable trees or other plants, 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. 
• Many crops are sensitive to SYNCHRONY® XP (mp). All 
direct or indirect contact (such as spray drift) with crops other 
than soybeans should be avoided. 
• Thoroughly clean all application equipment immediately after 
use and prior to spraying crops other than soybeans. 
RESISTANCE 
When herbicides that affect the same biological site of action are 
used repeatedly over several years to control the same weed 
species in the same field, naturally-occuning resistant biotypes 
may survive a correctly applied herbicide treatment, propagate, 
and become dominant in that field. Adequate contml of these 
resistant weed biotypes cannot be expected. If weed control is 
unsatisfactory, it may be necessary to retreat the problem area 
using a product affecting a different site of action. 
To better manage herbicide resistance through delaying the 
proliferation and possible dominance of herbicide resistant weed 
biotypes, it may be necessary to change cultural practices within 
aod between crop seasons such as using a combination of tillage, 
retreatment, tank-mix partners and/or sequential herbicide 
applications that have a different site of action. Weed escapes that 
are allowed to go to seed will promote the spread of resistant 
biotypes. 
It is advisable to keep accurate records of pesticides applied to 
individual fields to help obtain information on the spread and 
dispersal of resistant biotypes. Consult your agricultural dealer, 
consultant, applicator, aod/or appropriate state agricultural 
extension service representative for specific alternative cultural 
practices or herbicide recommendations available in your area. 
INTEGRATED PEST MANAGEMENT 
DuPont recommends the use of Integrated Pest Management 
(!PM) programs to control pests. This product may be used 
as part of an Integrated Pest Management (!PM) program 
which can include biological, cultural, and genetic practices 
aimed at preventing economic pest damage. App~ication of 
this product should be based on !PM principles and practices 
including field scouting or other detection methods, correct 
target pest identification, population monitoring, and treating 
when target pest populations reach locally determined action 
10 
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 or site systems in your area.

Directions For Use 
SYNCHRONY® XP (mp) at I to 3 ozJacre may be used for bumdown and residual weed control in all states 
located in SYNCHRONY® XP (mp) Rotational Regions A and B on the main Federal Section 3 SYNCHRONY 
XP (mp) product label, excluding the state of Florida (refer to Rotational Crop Guidelines). 
Application Timing - SYNCHRONY® XP (mp) may be applied to no-till or conservation tillage fields 45 days 
before planting soybeans to just before soybean emergence. Do not apply to frozen ground. 
Application Rates: 
Medium and Fine Soils, 
1.5 - 4% Organic Matter

up to 3 ozJacre 
* In Michigan, do not apply the I ozJacre rate to soils exceeding 
pH 7.6. In all other states, the soil pH is unrestricted for I ozJacre 
rate.

For season-long control of all grass and broadleaf weeds following 1 - 3 ozJacre applications of 
SYNCHRONY@ XP (mp), a planned sequential program is required. Use higher rates of SYNCHRONY@ XP 
(mp) where longer residual control is desired. 
Weeds Controlled 
Burndown Control of existing winter and summer annual weeds 
SYNCHRONY@ XP (mp) applications will provide bumdown control of certain broadleaf weeds which are 
no greater than 3 inches in height. 
To obtain bumdown of the weed species listed below: 
• Addition of Crop Oil Concentrate at 1 % v/v (1 gallon per 100 gallons of final spray volume) is required. 
• Use a minimum of 20 gallons per acre with spray nozzles that provide thorough spray coverage of the 
weeds. 
• 2,4-D L VE may be added for enhanced bumdown control. 
Bitteicress, small- Henbits Pigweed Tansy mustard 
flowered Lambsquarters Ragweed, common Thistle - Canadian (above 
Bushy wallflower Lettuce. prickly Ragweed, giant ground portion) 
Buttercup, smallflower Marestail* Shepherdspurse Velvetleaf

Dandelion Pennycress Speedwell (field, Yellow rocket 
Deadnettle (purple, red) Pepperweed Purselane) 
Garlic, wild* Sunflower .. * AddItIOn of 1 pt/acre 2,4-D LVE IS reqUIred for the 1 ozJacre rate of SYNCHRONY@XP(mp). and 
recommended for all other rates. 
To bumdown annual grasses and broadleaf weeds listed above when they exceed the recommended height. 
SYNCHRONY@ XP (mp) may be tank mixed with other herbicides registered for preemergence or bumdown 
application prior to soybean emergence. When tank mixing with glyphosate-containing products, replace the 
Crop Oil Concentrate with nonionic surfactant at 0.25% v/v (1 quart per 100 gallons final spray volume) and 
follow the manufacturer's instructions for ammonium sulfate addition. 
Preemergence Residual Control 
Applications of l.25 - 3 ozJacre SYNCHRONY@ XP (mp) will provide preemergence control or partial control 
(suppression) of the following weeds: 
Control 
Cocklebur 
Lambsquarters 
Marestail 
Pigweeds (redroot, smooth) 
Purselane Speedwell 
Ragweed, common 
Smartweeds. annual 
Velvetleaf 
Suppression

crabgrass. panicum) 
Chickweed, cornmon 
Jimsonweed 
Momingglory, annual 
Nutsedge. yellow 
Prickly Sida (tea weed) 
Ragweed. giant 
If applying 1 ozJacre of SYNCHRONY@ XP (mp). heavy weed pressure. delayed planting, or adverse 
environmental conditions may require additional bumdown control measures at planting. For enhanced residual 
control. products such as 2-4 ozJacre "Sencor" may be tank mixed with I ozJacre SYNCHRONY@ XP (mp). 
Early spring applications of 1 ozJacre SYNCHRONY@ XP (mp) will provide limited residual control of the 
above-listed weeds to contribute to a clean seed at planting.

Planned Sequential Programs 
SYNCHRONY® XP (mp) will not provide adequate season-long preemergence control of annual grasses and 
all broadleaf weeds. For season-long control, follow SYNCHRONY® XP (mp) with postemergence herbicide 
applications based on targeted weeds. To insure maximal rotation flexibility when considering a sequential 
program of SYNCHRONY® XP (mp) followed by CLASSIC® or SYNCHRONY® XP(mp), carefully 
consider: the soil pH, the recommendations below, the rotational information in this section, and the Rotational 
Crop Guidelines on product labeling. 
Applications of 1 ozlacre SYNCHRONY@ XP (mp) [Region A and B states] to soils with pH 
greater than 7: Do not apply additional chlorimuron-ethyl-containing herbicides (CLASSIC@, 
SYNCHRONY@ XP) except in the states of AL, AR, GA, LA, MO bootheel, MS, NC, OK, SC, TN, 
and TX, where up to 0.5 oz/acre SYNCHRONY@XP (mp) may be applied. 
Applications of 1.5 ozlacre SYNCHRONY® XP (mp) [Region B states] to soils with pH greater than 7: Do 
not apply additional chlorimuron-ethyl-containing herbicides (CLASSIC®, SYNCHRONY® XP) 
Applications of 1-3 oz SYNCHRONY® XP (mp) to soils with pH less than 7 may be followed with a single 
postemergence application of CLASSIC® or SYNCHRONY® XP. See table below for rates that may be 
applied: 
Expanded Application Rate CLASSIC® SYNCHRONY® XP (mp)

2.6 - 3 up to 114 none 
Refer to the sequential herbicide labels for specific information regarding use rates, application timing, crop 
rotations and other restrictions and precautions. 
Rotational Crop Information 
For rotational crop information following 1 ozlacre SYNCHRONY® XP (mp) in Region A states, and up to 1.5 
ozlacre applications in Region B states, use Recrop Interval 1 or 2 under the Section 'Rotational Crop 
Guidelines' on the main Federal Section 3 SYNCHRONY XP (mp) product label, depending on whether the use 
was in a Region A or Region B state. 
For all other applications of SYNCHRONY® XP (mp) under this supplemental labeling, follow the recropping 
intervals given in the table below. Crop rotation intervals noted in the table below are based on crops grown 
under favorable growing conditions. Crops grown under unfavorable environmental conditions, such as drought, 
nutrient deficiency, high salts, disease and insect pressure may demonstrate reduced tolerance to crop protection 
chemicals. When deciding on a particular crop to replant in your fields, carefully consider your particular soil 
and other field conditions.

* Field Corn is defined to include only that corn grown for grain, silage, popcorn, and seed com. However, 
because seed com inbred lines may vary in their sensitivity to trace amounts of herbicide carryover, DuPont 
cannot warrant that seed corn can be recropped without damage or yield loss. Users should seek the advice of 
their seed com company agronomists regarding inbred sensitivity to herbicides prior to planting any inbred 
lines. 
**In the states of DE, KY, MD, MO bootheel, NJ, NC, SC, TN, VA, and WV, field com may be recropped after 
9 months if the SYNCHRONY@ XP (mp) rate does not exceed 2.5 ozlacre.
