• DuPont™ SYNCHRONY® STS® DF berbicide is a 
dispersible granule formulation which readily dissolves in 
water . 
• SYNCHRONY® STS® DF may be used in conventional, 
no-till, or conservation tillage soybean production. 
TIming To Crop Stage 
SYNCHRONY® STS® DF, for in-season use, may be 
applied any time after the first trifoliate has opened but no 
later than 60 days before soybean maturity, 
• SYNCHRONY® STS® DF, for burndown use, may be 
applied up to 30 days before planting, or prior to soybean 
emergence after planting. 
2 
Timing To Weeds 
Apply SYNCHRONY@ STS", OF when weeds are young 
and actively growing (after the first true leaves have 
expanded, but before the weeds exceed the size indicated 
below), 
Applications made to weeds larger than the sizes indicated 
below, or to weeds lmder stress, may result in unsatisfactory 
control. 
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® STS® OF with any other 
approved soybean pesticide, always read and follow all use 
directior", restrictiens and precautions of both SYNCHRONY® 
STS® OF and the tank mix partner(s), When tank mixing, the 
most restrictive labeling applies. 
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,

Precautions for 0.25 oz SYNCHRONY® STS® DF uses 
• A temporary crop response may occur following an 
application of SYNCHRONY® STS® OF to soybeans not 
designated "STS" in the variety name.

• Applications rrude 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 .md,'or reduced weed control effectiveness. 
• Do not tankmi' "Poast Plus" with 0.25 ovacre OuPont™ 
SY~CHRO"y;l: STS® OF unless the soybean is designated 
as an "STS" variety. 
MIXING INSTRUCTIONS

APPLICATION EQUIPMENT 
Ground Application 
(See Also Spray Drift Management) 
BroadcDSl App6clllion 
Postemergence in scybeans, use a minimwn of 10 gal water 
per acre. Under heavy weed pressure or dense crop foliage, 
increase minimwo spray volwoe to 15·25 gal per acre. 
Use flat fan nozzles at 25-60 psi for SYNCHRONY@ STS® 
OF applications. 
For bumdown applications of existing vegetation, flat fan 
nozzles and a minimum of20 gallons per acre are 
recommended sc as to thoroughly wet the foliage to be burned 
down. 
Do not use flood, rain drop, whirl chamber, or controlled 
droplet applicator (COA) 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 Appliclllion 
Because band applicators spray a narrower area than broadcast 
applicators, use proportionately less spray sclution 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 volwnes, calibration, and spray pressure for band 
applications.

Use a minimum of 3 gal water per acre. Under heavy weed 
pressure or dense crop foliage, increase the minimum spray 
volwne 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 
SYNCHRONY® STS® OF 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® STS® OF will provide 
complete control of susceptible weeds in 7·21 days. Suppressed 
plants may remain green but will be stunted and noncompetitive. 
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® STS® OF if rain is expected 
within 
I hour or weed control may decrease.

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 ~mples taken for soil 
fertility recommendations, may not detect areas of high pH. Sub­
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 I: I soil:water 
suspension. 
SPRAYER PREPARATION AND CLEANUP 
Prior to application of DuPont™ SYNCHRONY® STS® 
DF, 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 ofSYNCHRONY® STS® DF 
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® STS® DF 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. 
Tum 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. 
8 
STEP 5. Thoroughly rinse the sprayer. hoses, boom and 
noutes with clean water, several times. 
Clean al1 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.

SPRAY DRIFT MANAGEMENT 
The interaction of many equipment and weather-related 
factors determines the potential for spray drift. The 
ap~)liCdtor i,,, f(sponsihle for considering all thes,'O factors 
wben making application decisions. 
A VOIDING 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, 
Temperature and Humidity, and Temperature Invenions 
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. 
Pnssure - Use the lower spray pressures recommended 
for the nozzle. Higher pressure reduces droplet size and 
does not improve canopy penetration. WHEN HIGHER 
FLOW RATES ARE NEEDED, USE A HIGHER­
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 minimwn 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 Height - Application more than lOft above 
the canopy increases the potential for spray drift.

-----_. __ ._- --
BOOM HEIGHT 
Setting the boom at the lowest labeled height (if specified) 
which provides unifonn coverage reduces the exposure of 
.iroplets to evaporation and wind. For ground equipment, the 
boom should remain level with the crop and have minimal 
oounce. 
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. 
~ote: Local terrain can influence wind patterns. Every 
applicator should be familiar with local wind patterns and 
bow 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 moming. 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 and/or 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. 
Note: 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. 
9 
AIR ASSISTED (AIR BLASn 
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. 
In addition to the general drift management principles 
already described, the following specific practices will 
further reduce the potential for drift.: 
Adju.st deflectors and aiming devices so that spray is only 
directed into the canopy. 
Block off upward pointed nozzles when there is no 
overhanging canopy. 
Use only enough air volume to penetrate the canopy and 
provide good coverage. 
• Do nol allow spray to go beyond the edge of the cultivated 
area. Spray the outside row only from outside the 
planting. 
IMPORTANT PRECAUTIONS 
"""riot" ··:e~1i.ttl'(Or1iaiVes1l~J~ 
.~L~I:,y)~~~~,,~tf'-~~4i;;.i'i~4i~~ 
Injury to or loss of desirable trees or vegetation may result from 
failure to observe the following: 
Do not apply DuPontr .. SYNCHRONY® STS® OF 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® STS® DF. 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. 
INFORMATION ON RESISTANT WEEDS 
When herbicides with the same mode of action are used 
repeatedly over several years to control the same weed species in 
the same field, naturaIIy-<JCcurning resistant weed biotypes may 
survive a correctly applied herbicide treatment, propagate, and 
become dominant in that field. These resistant weed biotypes 
may not be adequately controlled. Cultural practices such as 
tillage, preventing weed escapes from going to seed, and using 
herbicides with different modes of action within and between 
crop seasons can aid in delaying the proliferation and possible 
dominance of herbicide resistant weed biotypes.
