weed control. 
Use a petroleum-based crop oil concentrate 
(0.5% v/v) with at least 15% emulsifiers/surfactant. 
The use of crop oil concentrate may result in temporary crop 
injury. 
Ammonium Nitrogen F em/juf 
An ammonium nitrogen fertilizer is required in addition D a 
surfactant or a crop oil concentrate. 
• Use a high-{}uality liquid nitrogen fl:rtilizer ~uch r.s 
28-0-0 at a ratc of 2-4 quarts pcr acre, or I 0-34~O at a

• Usc a minimum of 5 gallons of water per acre. 
ENVIRONMENTAL CONDITIONS 
AND BIOLOGICAL ACTIVITY 
CONCERT SP provides best poslemergence results when 
applied to young. actively growing weeds_ Degree of 
control and duration of effect depend on: application rate. 
weed spectrum. weed size. growing conditions at and 
following time of treatment. soil moisture. precipitation. and 
spray adjuvants. Some weeds. such as lambsquarters. are 
more affected by stress than others. Delay application until 
streSS passes and weeds start to grow again_ Treating weeds 
under stress or large weeds may result in only partial 
control. Condilions that are conducive to healthy, actively 
growing plants optimize Jle performance of CONCERT SP. 
• If rain is expected within I hour. do Got apply CONCERT 
SP. or weed control may be decreased. 
• Applicalions made during or immediately following 
periods of abnormally cold weather for soybeans may 
result in less than satisfactory weed control. 
• Poor weed control or crop injury may result from applica­
tions made to plants under stress from 
I 
abnormal hot or cold weather. 
• growing conditions such as drought or 
water-saturated soil. 
disease. or 
nematode. insect. or prior herbicide injury. 
Delay application until stress passes and weeds and 
,oyocans resume growth. Severe stress from rnnditions 
immediately following application may also result in crop 
injury or poor weed control. 
• Applications during periods of hot and humid we.!her 
increase Ihe risk of crop injury 
Wilting. temporary leaf yellowing. reddened veins. andlor 
growth retardation of soybeans may follow application of 
CONCERT SP. The growth retardation is generally in the 
form of shone ned internode spacing. These effects will 
generaily be most evident 5-7 days after application. The 
soybeans will recover quickly under favorablr grnw;ng 
conditions.

CULTIVATION 
A timely cultivation may be neces"")' to control suppressed

application. or weeds that emerge after an application c' 
CONCERTSI'. 
Do not cultivate before. during. or wiU,in 7 days after the

Field Bioassay for Other Crops 
All other crops require a successful field bioassay. 
The suggested interval before initiating a bioas"ay is 
9 months. If the crop you want to plant docs not appear in the 
table above. you must complete a successful field :>ioassay 
during the season before planting. 111c field bioassay will detect 
small quantities of CONCERT SP that can remain in the soil 
a:>d could potentially injure rotational crops. A successful field 
bioassay means growing to matunty a test strip of crop(s) 
intended for production the following ycar.111c test strip should 
cross the whole field, including knolls and low areas. 
SPRAYER PREPARATION AND CLEANUP 
It is import,lIltthat spray eqUIpment is clean and free of previous

When cleaning spray equipmenl lX'forc applyi,'g 
CONCERT SP. read and follow label directions for proper 
rinsate disposal of the product previously sprayed. 
A steam cleaning of aerial spray tanks is recommended to 
dislodge any visible pesticide deposits. 
When spraying or mixing equipment will be used over an 
extended period to apply multiple loads of CONCERT SP, 
partially fill ule tank with fresh water at U,e end of each day of 
spraying, flush the boom and hoses. and allow 10 sit 
overnight. 
Cleanup Plocedure 
I. Drain li'~ ;ank and thoroughl) hose down the interior 
surfaces. Flush the tank. hosc:;, and boom with clean 
water for a minimum of 5 minutes. 
2. Partially till the tank with clean water and add one gallon 
of household ammonia" (containing 3% active) for every 
100 gallons of water. Finish filling the tank with water, 
then flush the c1euning solution through th~ hoses, boom, 
and nozzles. Add more water to com-pletely fill the IlIlk 
and allow 10 agitate/recirculate for al lea.<t 15 minutes. 
Again, flush the hoses, Jy~:>m, and nozzles with the 
cleaning solution, then drain the tank. 
3. Repeat Step 2. 
4. Remove the nozzles and screens and clean separately in a 
bucket containing the cleaning agent and water. 
5. Thoroughly rinse the tank with clean water for a 
minimum of 5 minutes, flUShing the water through the 
hoses and boom. 
• Equivalent amounlS of an alternate strength ammonia solution 
may be used, or a tank cleaner recomMended in the DuPont 
bulletin "Sulfonylurea Herbicides. A Guide 10 Equipment 
Cleanout." 
SPRAY DRIFT MANAGEMENT 
111c interaction of many equipment and weather -related factors 
detennines the potential for spray drift The applicator is 
responsible for considering all these factors when making appli­
calion decisions. 
AVOIDIl'<G SPRA Y DRH'T IS TilE RESPONSmn.ITY OF 
THE APPLICATOR. 
IMPORTANCE OF DROPLET SIZE 
The most effective way to reduce drift potential is to apply large 
droplets (> 150 - 200 microns). 111c best drift managemenl 
suategy is to apply the largest droplets that provide sufficient 
coverage and control. 111c presence of sensitive species nem,y,

) 
Pressure - Usc the lower spmy pressures reconuncnded for 
the nozzle. Higher pressure reduces droplet size and docs not 
improve canopy penetration. WHEN HIGHER FLOW 
RATES ARE NEEDED, USE A HIGHER-CAPACITY 
N07ZLE INSTEAD OF INCREASING PRESSURE. 
Nozzle Type - Use a nozzle type that is designed for the 
intended application. With mostnozzie types, IIdITower spmy 
angles produce larger dropl~r~. C,.,o:cler using I"w-drift 
noules. 
Controlling Droplet Size· Aircraft 
• Number of Nozzles - Use the minimum number of noules 
with the highest flow rate that provide uniform coverage. 
Nozzle Orientation - Orienting noules so that the spray is 
emined backwards, parallel to the airstream will produce 
larger droplets than other orientations. 
Nozzle Type - Solid stream nozzles (such as disc and core 
with swirl piate removed) oriented straight back produce 
larger droplets than other noule 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 
Sening the boom at the lowest labeled height (If specified) 
which provides unifoml coverage reduces the exposure of 
droplets to evaporatiOlI and wind. For ground equipment. the 
boom should remain level with the crop and have minimal 
boonce. 
WIND 
Drift potential increases at wind speeds of less than 3 mph (due 
10 inversion potential) or more than 10 mph. However, many 
factors, including droplet size and equipmcnttype detennine 
driti potential at any given wind speed. A VOID GUSTY OR 
WINDLESS CONDmONS. 
Note: Local terrain c;m influence wind pallems. Every appli­
calor should be familiar With local wmd pallems and how they 
affect spray drift. 
TEMPERATURE AND HUMIDITY 
When making applications In hot and dry conditions, sci up 
equipment to produce larger droplets to reduce effects of 
C"'lpordlion. 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature mversion. 
Temperature inversions restrict vertical air mixing. which 
causes small suspended droplets to remain close to the ground 
ard move laterally In a concentmted cloud. Temperature 
Inversions arc lharal:tcriled by increasing lempcmture with 
altitude and are common on nights with tinuted cloud (OVer

SHIELDED SPRA YERS 
Shielding the boom or individual nozzles can reduce the 
effeclS of wind. H:>wever, it is the responsibility of the appli­
cator to verify that the shields arc preventing drift and not 
interfering with unifonn deposition of the product. 
INFORMATION ON RESISTANT WEEDS 
(,~'I 
When herbicides with the same mode of action are used 
repeatedly over several years to control the same weed 
species in the same field. naturally-occuning resistant ,·.·eed 
biotypes may survive a correctly applicd herbicide 
treatment, propagate. arid become dominant in that field. 
These resistant weed biotypes may not be adequately 
controlled. Cultural practices such .. nillage. preventing 
weed escapes from going to seed. and using herbicides with 
different modes of action within and belWeen crop seasons 
can aid in delaying the proliferation and possible dominance 
of herbicide resistant weed biotypes.

F..NVIRONMENTAL CONDmON~ AND BIOLOGICAL ACflVTIY 
CONCERT SP rapidly inhibits the growth of su.reptible weeds. reduc­
ing weed competition hours after applic.tion. Leayes tum yellow 5-7 
days after postemergenee applicalion. followed by death of the weed's 
growing point. Susceptible plants are controlled in 7-21 days. Death of 
leaf tissue will follow in some species, while others will remain green 
but stunted and noncompetitive. 
CONCERT SP proyides best postemergence results wh-, applied to 
young. actiYely growing weeds. Degree of control and duration of effect 
depend 011: application rate. weed spectrum. weed size. growing condi­
tions at and following time of treatment. soil moisture. precipitation. 
and spray adjuvants, Some weeds. such as lambsquarters, are more 
affected by stress than others. Delay application until ',ress passes and 
weeds sUirt to grow again. Treallng weeds under slress or large weeds 
may resull in only partial control. Condilions Iba! are conduciye to 
healthy. lctiyely growing plants optimize tbe performance of 
CONCERTSP. 
If rain is expected within I bour. do not apply CONCERT SP. or weed 
conrrol may he decreased. 
Applications made during or immediately following periods uf abnor­
mally cold weather for soybeans moy resull in less than satlSfactory 
weed conlrol. 
Poor weed conlrol may result from applications made to plants under 
stress from abnormal hot or cold weather, growing conditions such as 
droughl or water· saturated soil. disease. or nematode. insect, or prior 
herbicide if.jury. Delay application until slress passes and weeds and 
soybeans resume growth. Severe stress from conditions immediately 
following application may also resull poor weed control. 
CULTIVATION 
A timely cullivation may be necessary to control suppressed weeds. 
weeds that were beyond the maximum size :11 the time of application, or 
weeds that emerge after an application of CONCERT SP. 
Do not cultiyate before. during. or within 7 days after the application. 
Cultiyation may decrease wccd control by pruning roots and placing 
the weed under stress. 
The best time to cultiyate is approximately 14 days after application.

• When usong CONCERT SP :Ierbicide, the tenn "FIELD CORN" IS 
defined to include only that com grown for ~rain or silage, popcorn. and 
seed com relative to the Rotational Crop Guidelines seclion of this label. 
"Field Rioassay for Other Crops. All other crops require a successful 
field bIoassay. The suggested interval before initiating a bioassay is 9 
months. If the crop you want to plant does not appear in the table above. 
you must complete a successful field bioassay during the season before 
planting. The field bio"-'5ay will detect small quantiti ... of CONCERT 
SP that can remain in the soil and could potentially injure rotalional 
crops. A successful field bioassay means growing to maturity a test strip 
of crop(,) intended for production the following year. The test strip 
should cross the whole field. including Itnolls and low areas. 
SPRAYER PREPARATION AND CLEANUP 
It is important that spray equipment is clean and free of previous pesti­
cide deposits before wing CONCERT SP. and then properly cleaned out 
following application. Clean all application equipment before applying 
CONCERT SP. Follow the cleanup procedures specified on the label of 
the product previously sprayed. If no cleanup procedure is provided. use 
)the procedure thar follows. Immediately following applications of 
. CONCERT SP. 'horoughly clean all mixing and spray equipment to 
avoid applications to crops other than soybeans. 
Cleanup Procedure 
I. Drain the tank and thoroughly hose down the interior surfaces. Rush 
the tank., hoses, and boom with clean wdter for a minimum of 5 
minutes. 
2. Partially fill the tank with clean water and add one gallon of house­
held ammonia' (containing 3% active) for every 100 gallons of 
water. i'inish filling the tank with water. then flush the cleaning solu­
tion through the hoses. boom. and nozzles. Add more water to com­
pletely fill the tank and allow to agitateirecirculate for at least 15 
minurcs. Again, flush the hoses. boom. and nozzles with the cleaning 
solution, then drain the tank. 
3. Repeat Step 2. 
4. Re!T1('ve the nOlzle~ and screens and clean scp'U'iltely in a tuckCL con­
) tainlng the cieaninE: agent and water. 
5 ThorOlighly rinse the lank with clean water for a minimum of 5 
minutes. flushing the water through the hoses and bJOm . 
• Equivalent amounts of an alternate strength ammonia solution may be 
useJ or Du?ont approved cleaner can be used in the de:mout procedure 
(see DuPont Bulletin "Information on Cleaning Agents for Spray~r 
Clcanout of DuPont Sulfonylurea lIerbiCl!Jes"). Carefully ,cad and 
follow the indiVidual cleaner instructions.

PROGRAM 
Apply CONCERT SP at the rate of 112 ounce per acre (one Soluble 
Pack per 4 acres) for control of the weeds on the CONCERT SP label. 
Include spray additives as recommended on the CONCERT SP label. 
Dest results are obtained when CONCERT SP is applied to weeds that 
are young (after the fim true leaves have expanded. but before they 
exeeed the size indicatcd on the label and actively growing. 
Applications made to weeds that are in the cotyledon stage. or larger 
than the sizes indicaled. or to weeds under stress (weather. herbicide. or 
other) may result in unsatisfactory control. Apply after the f.;;,\ trifoli­
ate of the soybean ha:~ fully expand.:d and the plants are active::'

Ground Application:" 
Broadcast Application 
Use 10·25 gallons of water per acre 
Usc nat fan nozzks at 25 - 40 psi. 
Do not usc flow, hollow cone, rain drop. whirl chamber or controlled 
droplet applicator (CDA) type nozzles as unacceptable crop injury, 
excessive spray drift. or poor weed cor.tr.>1 may result. 
For proper spray coverage, adjust the boom and nozzle height accord­
i"g to the specifications listM by the nozzle manufacturer. 
Band Application 
For band application, use proportionately less spray mixture. 
To avoid crop injury, carefully calibrate the band applic::tor so as not 
to exccM the labeled rate. 
Carefully follow the manufacturer's instructions for r,ozzle type, (Oat 
fan preferred), nozzle orientation, distance of the nozzles from the 
crop and weods, spray vol limes, calibration, and spray pressure. 
} For additional information on row banders, see DuPont bulletin 
.. Application Accuracy - Row Banders". 
I,erial A pphcation 
Use nozzle types and arrangements that will provide for optimum 
spray distribution and m""num coverage at5 to 10 gallons per acre. 
Do nor :::'jJplY during a temperature inversion. when winds arc 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 special directions for aerial application. 
I!lIPORTANT PRECAUfIONS

Apphcallolls of CONCERT SP • "Pursuit" or CONCERT SP fol­
lowed by "Pursuit" may shorten stem internodal length and cause 
tcmrx>rary crop injury. Crop response may be increased when appli· 
cations afC made to soybeans that are under stress. Soybeans WIll 
recovC'[ quickly under normal growing conditions. 
Soyhcans should he free from stress and aClively growing at the time 
of application. Stress may be caused by abnormally hoi or cold 
weather, powmg condItions such as drought or water·saturate.d soil. 
disease. soil mHnent deficiencies such as iron chlorosis. or injury 
from nematodes. Insects. or prior herbicide applications.

HOW TO USE 
DuPont CONCERT 5P Herbicide may be tank mixed with "Blazer" for 
control of br('adleaf weeds not controlled by CONCERT 5P applied 
alone in soybeans. Refer to the "Blazer" label for other weeds which 
may be controlled or suppressed and the maximum size at application. 
Rate 
Use COr,CERT 51' at a rate of one 2-ouo<:" Soluble Pack per 4 acres 
(112 ounce pe' acre). Refer to the CON<::ERT SP label fo, the size and 
species of weeds controlled. Tank. mix with "Blazer" at a rate of 1/2 to 
1 112 pmts pcr acre. Refer to the "Biai.er"' label for the: appropriate rate 
based on :he weeds to be controlled dnd their size at th~ time of aoplica· 
tion.

('rccautioru: 
A temporary crop response should be expected following an applica­
tion of "Blaze,". Soybean leaves which are open at the time of "ppli­
cation will show some bum, bronzing and specklir.g. Soybc'.ans will 
quickly outgrow these herbicide effects. 
Best results are obtained when applications are made to weeds and 
soybeans which are young and actively growing. Applications made 
whr.n the crop and weeds are under stress f!"om moisture. cold. heal, 
high humidity, disease, insect pressure and prior herbicide stles:; 
may result in excessive crop response and/or reduced weed control 
effectiveness. 
A tank mix 0' CCJNCER r 51' + "Blaze'-' has occasionally resulted in 
~light reductions In control (ar.lagonism) of some broa1le1.f species 
versus appli1.'3tien of CONCERT SP alone. This antagonism can be 
largely overcome by making tank mix applications when the weeds 
arc at the smaller end of the size range gi .cn and when applications 
arc made under good growmg conditions and when weeds are free 
from stress. Altematively, a sequential application program should 
be considered. 
CONCERT 51' + "Blaze," may be tank mixed with a po'teme'gence 
grass hcrolcutc ~uch a~ DuPont ASSURE- II Herbicide. However, 
13nk ITIL'(ing of a po<;tcmefi!cllcc grass herhicide With postcmcrgencc

• CONCERT SP + "Cobra" m"y be tank mixed with a postemergence 
grass herbicide such as DuPont ASSURE" II Herbicide. However, 
taok mixing of a postemergence grass herbicide with postemergence 
broadle.f herbicides such as CONCERT SP and "Cobra" may result 
in a reduction of effectiveness or the postemergence grass herbicide

A temporary crop response should be expected following an applica­
tion of "Renex" 2LC. Soybean leaves which are open at the time of 
application will show some bum, bronZing, cnnkling and spotting. 
Soybeans will quickly outgrow these herbicide effects. 
Best results are obtained when applications are made to weeds and soy­
beans which arc young and actively growing. Applications made when 
the crop and weeds are under stre-ss rrom moisrure. cold. heat. high 
humidity, disease:, insect pressure and prior herbicide stress may result 
i(1 exce~sive crop response and/or reduced weed conlrol effectiveness. 
A tank mix of CONCERT SP + "Reflex" 2LC has occasionally 
resulted in 'light reductions in control (antagonism) of some 
broadleaf species versus application of CONCERT SP alone. This 
antagonism can be largely overcome by makmg rank mix appliLa­
(ions when the weeds are at the smaller end of the size range given 
and when apphcallop.s are made under good grow;ng tonditions iJnd 
when wceds are free rrom stress Alternatively, a ~cquential aprlil:3-

CONCERT SP + "Reflex" 2LC may be tank mIXed WIth a postemcr­
gence grass hcrbicide such as DuPont ASSURE- II Herbicide. 
H.,we'·cr. tank mixing of a postemergencc grass herbicide with poo;te­
