APPLICATION INFORMATION 
Du Pont CONCERT Herbicide is a convenient formulation 
designed for use by the custom applicator. The dispersible 
granule formulation readily dissolves in water. 
When to Apply 
CONCERT performs best when applied to small weeds a 
few weeks after planting. 
Timing to Crop StIIge 
• CONCERT may be applied to soybeans any time after the 
2 
first trifoliate has expanded fully. 
• Apply no latcr than 60 days before harvest. 
Timing to Weeds 
• Apply CONCERT when weeds arc young and actively 
growing (after the first true leaves have expanded. but 
befDie the weeds exceed the size indicated in the table 
below). . 
• 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.

spray adjuvanls. Some weeds, such as larnbsquarters, are 
more affected by ,tress 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. Conditions that are conducive to healthy, actively 
growing plants optimize the performance of CONCERT. 
• If rain is expe,ted within I hour. do nOi apply 
CONCERT. or weed control may be decreased. 
• Applications 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 
• 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 
soybeans resume growth. Severe stress from conditions 
immediately following application may also result in crop 
injury or poor weed COlotrol. 
• Applications during periods of hot and humid weather 
increase the risk of crop injury. 
Wilting, temporary leaf yellowing, reddened veins, andlor 
growth retardation of soybeans may follow application of 
CONCERT. The growth retardation is generally in the form 
of shortened internode si>acing. These effects will generally 
be most evident 5-1 days after application. The soybeans 
will recover quickly under favorable growing conditions. 
CONCERT rapidly inhibits the growth of susceptible 
·,>;eeds. reducing weed competition hours after application.

green but stunted and noncompetitive. 
CULTIVATION 
A timely cultivation may be necessary to control suppressed 
weeds, weeds that were beyond Ole maximum size at the 
t,me of application, or weeds that emerge after an applica­
tion of CONCERT. 
• Do nol cultivate before, during, or within 1 days after the 
application. 
Cultivalion may decrea,e weed control by pruning roots 
and placmg Ihe weed under stress. 
• The besl time 10 cultivale is approximalely 14 days afler 
applicalion.

• When using CONCERT Herbicide, the tenn "FIELD CORN" is 
defined to include only that corn grown for grain or silage, 
popcorn, and seed com relalive to the Rotational Crop Guidelines 
section of this label. 
Field Bioassay for Other Crops 
All ether 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 bioassay will 
detect small quantities of CONCERT that can remain in the 
soil and could potentially injure rotational crops. A successful 
field bioassay means growing to maturity a test strip of 
crop(s) intended for production the following year. The test 
strip should cross the whole field, including knolls and low 
areas. 
SPRAYER PREPARATION AND CLEANUP 
It is important that spray equipment is clean and free of 
previous pesticide deposiL' before using CONCERT, and then 
properly cleaned out following application. aean all applica­
tion equipment before applying CONCERT. Follow the 
cleanup procedurrs specified on the label of the product previ­
ously sprayed. If no cleanup procedure is provided, usc the 
procedure that follows. Immediately following applications of 
CONCERT, thoroughly clean all mixing and spray equipment 
to avoid applicatiom to crops other than soybeans. 
NollS 
When cleaning spray eqUIpment before applying 
CONCERT, read and follow label directions for propel

Cleanup Procedure 
I. Drain the tank and thoroughly hose down the interior 
surfaces. Flush the tank, hoses, and boom with dean 
water for a minimum of 5 minutes. 
2. Partially fill the tanK with clean water and add One gallor. 
of household ammonia" (containing 3% active) for every 
100 gallons of water. Finish filling the tank with water, 
then flush the cleaning solution through the hoses. boom, 
and nozzles. Add more water to completely fill the tank 
and allow to agitate/recirculate for at least 15 minutes. 
Again. flush the hoses, boom. and nozzles with the 
cleaning solution, then drain the tank. 
3. Repeat Step 2. 
4. Remove the nozzles and screens and clean sepa lItely 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 amounts of an alternate strength ammonia solution 
may be used, or a tank cleaner recommended in the DuPont 
bulletin "Sulfonylurea Herbicides. A Guide to Equipment 
Cleanout. " 
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 appli­
cation decisions. 
A VOIDING SPRAY DRIFT IS THE RESPONSIBJUfY OF 
THe APPUCA TOR. 
IMPORTANCE OF DROPLET SIZE 
The most effective way to reduce drift potential is 10 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 DRIFr POTENTIAL, BlIT 
WILL NOT PREVENT DRIFr IF APPUCA nONS ARE 
MADE IMPROPERLY OR UNDER UNFAVORABLE E/Io'VI­
RONMENTAL CONDmONS! See Wind, Temperature and 
Humidity. and Temperature 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 dropkt size and does not 
improve canopy penetration. WHEN HIGHER FLOW 
RA 11'.5 ARE NEEDED, USE A HIGHER·CAPACITY 
NOZZLE INSTEAD OF INCREASING PRESSURE. 
Nozzle Type - Use a nonle type that is designed for the 
intended application. With ITl<"t n07zle types, n"rmwer spray 
angles produce larger droplcl'. Consi,ler using low·drift 
nooks.

) 
) 
Controlling Droplet Size - Aircraft 
Number or Nozzles - Usc 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 airs~am will produce 
larger droplets than other orientations. 
• Nozzle Type - Solid stream nozzles (such as disc and core 
with swrrl plate removed) oriented strnight back produce 
larger droplers 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 IIlOIe than \0 ft above the 
canopy increases the potential for spray drift 
BOOM HEIGHT 
Setting the boom at the lowest labeled height (if specified) 
which provides uniform coverage reduces the exposure L~ 
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 potenticl) or more than \0 mph. However. many 
factors. including droplet size and equipment type determine 
drift potential at any given wind speed. A VOID GUSTY OR 
WINDLESS CONDmONS. 
Note: Local terrain can influence wind panerns. Every appli· 
cator should be familiar with local wind panems 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. 
T~mperature inversions restrict venical air mixing. which 
causes small suspended droplets to remain close to the ground 
and move laterally in a concentr .. ted cloud. Temperature 
inversions arc characterized by increasing temperature with 
altitude and arc 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, inver­
sions 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 dissipares indicates good venical 
air miXing. 
SHIELDED SPRA YERS 
Shielding the boom or individual nonles can reduce the 
effects of wind. However, it is rhe responsibility of the appli· 
calor to verify that the shields arc preventing drift ami not 
interfering with uniform dCPo\llion of the pnKluc1. 
INFORMATION ON RESISTANT WEEDS 
When herbicides with the same mode of action are used 
repeatedly over several years to control the s~me weed 
species in the same field, naturally. occurring 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 helbicides with 
different modes of action within and between crop seasons 
can aid in delaying the proliferation and possible dominanc~ 
of herbicide resistant weed biotypes. 
IMPORTANT PRECAUTIONS 
• CONCERT Herbicide should be used only in accordance 
with recommendations o~ this label or in separately 
published Du Pont recommendations. 
• Injury to or loss of desirable trees or vegetation may 
result from failure to observe the following:

Pncautions 
A lemporary crop response should be expecled following an applica­
lion of "Reflex·· 2LC. Soybean leaves which are open at Ihe lime of 
applicalion will show some bum. bronzing. crinkling and sponing. 
Soybeans will quickly oUlgrow Ihese herbici.!e effecls. 
Best results are obtained when applications are made to weeds and 
soybeans which are young and actively growing. Applicalions 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. 
A lank mix of CONCERT + "Reflex·' 2LC has occasionally resulled 
in slighl reduclions in conlrol (anlagonism) of some broad leaf species 
vo"us applicalion of CONCERT alone. This antagonism can be 
largely overcome by making lank mix applications when Ihe weeds 
are al Ihe smaller end of Ihe size range given and when applications 
arc made under good growing conditions and When weeds are free 
from stress. Alternatively. a sequential application program should 
he con~idcrC"d. 
CONCERT + ··Reflcx·· 2LC may he lank mixed wilh a po sIc mer· 
gence grass herbIcide such as DuPonl ASSURE" II Herbicide. 
However. tank mixing of a postemergence grass herbicide with poste· 
mergence broadleaf herbicides such as CONCERT and ··Reflex" 2LC 
may result In a rcdllc!ion of effectiveness of the po~lc01ergenC(.. grass 
herbicide on some grass species (antagonism). Bcst results arc

USE OF REDUCED RATES OF COBRA HERBICIDE WITH "CONCERT" HERBICIDE 
FOR CONTROL OF EASTERN BLACK NIGHTSHADE, COMMON WATERHEMP 
AND OTHER WEEDS IN SOYBEANS 
D1RECfIONS FOR USE 
It is a violation of federal law to use this product in a manner inconsis­
yent with ils labeling. 
HOW TO USE 
Tank Mixes 
DuPonl CONCERT Herbicide may be tank mixed wilh a «dueed rate of 
"Cobra" for conlrol of easlem black nightshade and common waler­
hemp and may also aid in control or suppression of other weed species 
Refer to the "Cobra" label for other weeds which may be controlled or 
suppressed and the maximum size at application. 
Rate 
Use CONCERT at a rale of 1/2 ounce per acre. Refer 10 Ihe CONCERT 
label for the size and species of weeds conI rolled. To control small 
nightshade (a maximum of 2" in hcighl). andlor common walerhemp (a 
maximum of 4" in height). add "Cobra" at a rate of 4 to 6 fluid ounces 
per acre. Usc the higher rate of "Cobra" for nightshade and waterhemp 
at or ncar the maximum size. 
Adjuvant. 
) Nonionic surfactant or crop oil concentrate must be added to the tank 
m,x. Usc as directed on the CONCERT label. If applying CONCERT 
+ "Cobra" to STSTW soybeans, reduce the amount of crop oil concen­
t,ale to 0.5% vlv (4 pmts per 100 gallons of spray solution). DO NOr

Sequential Application Program 
Apply CONCERT as directed an the product label. If nightshade or 
common w.terhemp emer,.es following an application of CONCERT. 
"Cobra" maybe appl;ed at a reduced rate of 4 to 6 fluid ounces per aerc. 
At this reduced rate nightshade must not exceeJ 2" in height and water­
hemp must not exceed 4" in height. If these weeds exceed these si7.e5 
or if other weeds are present, refer to the "Cobra" label for rate and use 
rccommendations. To minimize crop response an interval of at least 
seven days between applicatip.ns is recommended. 
Refer to the "Cob,," label for recommend,d surfactant and fertilizer 
adjuvants. 
Precautions 
A temporary crop response s~ould be expected following an ap~hca­
tion of "Cobra". Soybean leaves which are open at the time of appli­
cation will show some burn, bronzing and speckling. Trifoliate 
soyb...~n leaves which have em~rged but are unopened at the time of 
,pplieation may appear cupped at the tip andlor crinkled along the 
edges of the leaf. Soybeans will quickly outgrow these herbicide 
effects. 
B~st resulls arc obtained when applications ale made to weeds and 
soybeans ·which are young and actively growing. Applic:llions made 
when the crop and weeds are under stress from moisf'Jrc, cold, heat, 
hIgh humidity, disease. insect pressure and prior herbicide stress 
may result in exccssive crop re~ponse andlor reduced weed contlol 
effectiveness.

ILLINOIS, IOWA, MINNESOTA, NEBRASKA, SOUTH DAKOTA, AND WISCONSIN 
DuPonl CONCERT Herbicide may be applied in a lank mix. or as pan 
of a .;equenlial program. wilh a reduced rale of "Pursuil" for conlrol of 
small easlern bl,ck nightshade in Ihe slates of Illinois. Iowa. Minnesola. 
Nebraska. Soulh Dakola. and Wisconsin. 
) DlRECfIONS FOR USE 
It is a violation of federal law to use this product in a manner inconsis­
lenl with its labeling. 
"CONCERT" + PURSUIT TANK MIX 
A lank mix of CONCERT al Ihe rale of 1/2 ounce per acre plus 
"Pursuit" at a rate of 2.0 ounces per acre is recommended for postemer­
gence conlrol of Ihe weeds Iisled on Ihe CONCERT label and small 
easlern blac. ~;ghlsh3de. To be effective the nightshade weeds must nOI 
exceed 2" in height. Refer 10 Ihe CONCERT lahel for olher weeds con­
lrol;ed and maximum heighls. 
Besl results are obtained when Ihe CONCERT + "Pursuit"' lank mix is 
applied to weeds that are young (after the first true leaves have 
expanded. ~UI before they exceed the size indicaled on Ihis label) and 
aclively growing. This is generally 21-30 days afler planling of soy­
beans. Applications made to weeds that are in the cotyledon stage. or 
larger than the sizes indicated. or to weeds under stress (weather. herbi-
) ~~. ::o::e~ i::~::~~:d~:s;~::::t:~n~:~t::I~roadleaf weeds only. 
Other measures should be used to control grassy weeds. 
Speay Additives 
Postemergence apphcaCtons of CONCERT + "Pursuit" tank mix must 
include the addition of a nonionic surractant and ammontUJn nitrogen 
fertilIzer as descnbc:d below. For additional information refer to the 
DuPonl bulletin "Approved Adjuvants for Use With DuPont Row Crop 
and Cereal Herbicides" for a list of approved adjuvants. 
Use a nonionic surfactant at the rate of I pmt per 100 gal of solution 
(0.125% v/v). Under dry. cool (generally 7rf' F or less) conditions 
the rate of nonionic ~urfactant may be increased to 2 pint.s per 100 
gal. of solulion (0.25% v/v). 
Use a high quality nitrogen fertlli1~r product such as lR-O-O at a rate 
of 4 . 8 pints ~r acre. or 10-.14-0 at a rate of 2 - 4 pints per acre. 
Alternattly. a high-quality, o;pr;tyahle !!rade of amrnonlurr o;ulfate

Do not use Dash' Dash HC'. crop oil concenlrates or methylated seed 
oil products such as Sun-It II' when tank mixing CONCERT + 
"Pursuit" as excessive aop injury may occur. 
"CONCERT" FOLLOWED BY PURSUIT SEQUENTIAL 
PROGRAM 
Apply CONCERT at the rale oi 1/2 ounce per acre for conlrol of the 
weeds on Ihe CONCERT label. Include spray ad1itives as recom­
mended on the CONCERT label. Be" results are obtained when 
CONCERT is applied to weeds that are young (after the first true leaves 
h,ve expanded. bul before they exceed the size indicated on the label 
and actively growing. Applications made to weeds that are in the 
cotyledon stage, or larger than the sizes indicated. or 10 weeds under 
stress (weather. hert>icide. or other) may r-.sult in unsatisfactory conlrol. 
;.pply after the firsl trifoliate of Ihe soybean has fully expanded and Ihe 
plants are actively growing. 
If eastern black nightshade becomes a problem following the applica­
tion of CONCERT. an applicalion of a reduced rate of "Pursuit" can be 
made. "Pursuit"' may be applied at a rate of 2.0 ounces per acre ior 
control of small. aClively growing eastern black nightshade that does not 
exceed 2" in height. A minimum inlerval of 7 days between the 
CONCERT application and follow-up "Pursuil" treatment is advised to 
reduce the potential for crop injury and unsatisfactory weed control. 
Soybeans should be frcc from stress and aClively growing when the 
follow-up application is made. The soybean plants should have al leasl 
one newly emerged fully expanded Irifoliate prior to the follow-up 
aprlication of ··Pursuit". 
This program is recommended for the control of broadleaf weeds only. 
Other measures should he U5ed to control grassy weeds.

IMPORTANf PRECAUI'IONS 
, Use of CONCERT is not permilted in the slale of Nonh Dakota or 
that area of Minnesota nonh and west of highways MN 27 and US 
71. 
Applications within I hour of rain may reduce weed control. 
Applications of CONCERT + "Pursuit" or CONCERT followed by 
"Pursuit" may shorten stem inlernodal length and cause temporary 
crop injury. Crop response may be increased when applications = 
made to soybeans that are under stress. Soybeans will recover 
quickly under nonnal growing conditions. 
Soybeans should be free from stress and actively growing at the time 
of applicalion. Stress may be caused by abnormally hot or cold 
weather, growing conditions such as drought or water-saturated soil. 
disease. soil nutrient deficiencies such as iron Chlorosis. or injury 
from nematodes. insects. or prior herbicide applications. 
Cultivation .nay put w~cds under stress by pruning roots. thus reduc· 
mg weed control. Avoid cultivation 7-10 days prior to or following 
application of the herbicide treatmrnt. For maximum weed control, 
cultivate 7 -10 days aft., application. 
, Ref., to Ihe CONCERT and "Pursuit" Herbicide labels for additional 
use directions, use restrictions, rotational crop intervals and precau­
tions. The most restrictive provision on either label will apply.

TANK MIX OF "CONCERT" HERBICIDE WITH BLAZER POSTEMERGENCE HERBICIDE 
FOR BROADLEAF WEED CONTROL IN SOYBEANS 
DIRECTIONS FOR USE 
It is a violation of federal law to usc this product in a manner inconsis­
tent with its labeling. 
HOW TO USE 
DuPont CONCERT Ilerbicide may be tank mi.ed with "Blazer" for 
control of broadleaf weeds not controlled by CONCERT 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 CONCERT at a rate of 1/2 ounce per acre, Refer to the CONCERT 
label for the ~ize and species of weeds controlled. Tank mix w:li. 
"Blazer" at a rate of 1/2 to I 1/2 pints per acre, Refer to the "Blazer" 
label for the appropriate rate based on the weeds to be cont'olled and 
their size at the time of application. 
Adjuvants 
Nonionic surfactant must be added to the tank mi. at a rate of 0.125 to 
0.25% vlv (2 to 4 pints per 100 gallons of spray solution), Use as 
directed on the CONCERT label, 
Use of crop oil concentrate or vegetable origin oil is not recommended, 
as severe crop injury may occur. 
Ammonium nitrogen fertilizer may he added as directed on the 
CONCERT label. 
Mixing lrutructions 
I. Fill the sprayer tank 1/4 to 113 full with water. Regin agital d. 
2, Add the required amount of CONCERT Conlinue agitalion. 
3. Albw the CONCERT to fully disperse 10 the water. This will take 
several minutes. 
4. When lhe CONCERT is fully dispersed, resume filling the spray tank 
with water. Add the "Blazer". 
5. Add the spray adjuvants last, 
6. Maimam agitation throughout the spray application If tlu: mixtl Ie 
has seuled, thoroughly re,agitate before using. 
7. Apply the spray preparation wilhin 24 hours 10 aVOid product 
dcgradatlon 
Precautions 
A temporary crop response should be expected following an applica­
tion of "Blazer". Soybean leaves which are open al the time of appli­
cation will show some bum, bronzing and speckling. Soybeans will 
quickly outgrow these herhicide effects. 
Best results arc obtained when applicat!ons are made to weeds and soy­
bear.s which arc young and actively growing, 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. 
A tank mix of CONCERT + "Blazer" has occasionally resulted in 
slight reductions in control (antagonism) of some broad leaf species 
"crsus application of CONCERT alone. This antagonism can be 
largely overcome by making tank mix applications when the weeds 
are at the smaller end of the size range given and when applications 
are made under good growing conditions and when weeds are free 
from stress. Alternatively, a sequential application program should 
be considered. 
CONCERT + "Blazer" may be tank mixed with a postemergence 
grass herbicide such as DuPont ASSURE" II Herbicide. However, 
tank mixing of a postemergence grass herbicide y.oith postemcrgencr. 
broad leaf herbicides such as CONCERT and "Blazer" may result in a 
reduction of effectiveness of the postemergence grass herbicide on 
some grass species (antagonism). Best results are obtained if the 
grass herbicide is applied in a sequential program one day before or 
seven days following an application of the broad leaf herbicides. 
Refer to the postemergence grass herbicide label for additional mfor­
mation on antagonism.

.) DIRECTIONS FOR USE 
It is a violation of federal law '0 use this product in a manner inconsis­
lenl wilh ils labeling. 
The following recommendalions for use of DuPonl CONCERT 
Herbicide pertain only when applications are made to soybean varieties 
designaled as STS. 
The STS designation indicales Ihe soybean variely contains a propri­
etary trait that enhances the soybean's natura1 tolerance to DuPont 
sulfonylurea herbicides. Information on STS soybean varieties may 
be obtained from your seed dealer or DuPonl representative. 
Applicalion 10 soybean varieties not designated STS will resull in 
severe crop injury andhr yield loss. 
These STS varieties must be purchased from an authorized seed 
dealer. 
• DuPont will not warrant Ihe safety of this treatment to seed saved 
from previauj years production (bin·run seed).

APPLICATION EQUIPMENT 
Many crops are highly sensitive 10 CONCERT. All direct or indirect 
contacl (such as spray drifl) wilh crops olher Ihan soybeans should be 
avoided. 
Ground Application: 
Broadcasl Applicalion 
Use 10-25 gallons of waler per acre. 
Use f1al fan nozzles al 25-60 psi. 
Do nol use flood, hollow cone, rain drop, whirl chamber, or con· 
trolled droplet applicator (CDA) type nozzles. Excessive spray drift, 
or poor weed cOnlrol may resull 
For proper spray coverage, adjusllhe boom and nozzle height accord· 
ing 10 the specifications lisled by lhe nozzle manufacturer. 
Band Application 
For band application, use proportionately less spray mixture. 
Carefully calibrale the band apphcalor to nol exceed the labeled rate. 
Carefully follow Ihe manufacturer'S instructions for nozzle types (flat 
fan nozzles preferred), nozzle orientation, distance of the nozzles from 
Ihe crop and weeds, spray volumes, calibralion, and spray pressure_ 
For additional information on row banders. see DuPont bulletin, 
"Application Accuracy Row Banders." 
Aerial Application 
Use nozzle Iypes and arrangements Ihal will provide for optimum 
spray distribution and maximum coverage al 510 10 GPA. 
Do not apply <luring a lemperalure-inversion condition, when winds 
are gusty, cr when other .~.,wlions will favor poor coverage andIor 
olf-Iarget spray movement 
Use a minimum of 5 gallons of water per acre. 
ENVlRONMENL\L CONDnl0NS AND BIOLOGICAL ACIlVITY 
CONCERT rapidly inhibits Ihe growlh of susceplible weeds, reducing 
weed competilion hours afler applicalion. t,.,aves tum yellow 5·7 days 
) afler postemergence application, follow<d hy death of the weed's 
growing point. Susceplihle planls are controlied in 7·21 days. Death of 
leaf tissue will follow in some species, wh.le olhers will remain green 
but stunted and noncompetitive. 
CONCERT provides beSI poSlemergence resulls when applied 10 young. 
actively growing weeds. Degree:: of control and duration of effect 
depend on: 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 lambsq~aners. arc more 
affected hy stress than others. Delay application until stres~ passes and 
weeds start to grow again. Treating weeds under stress or large weeds 
may rcsuh in only partial control. Conditions that are conducive to 
heallhy, aCI.vely growing planl< opllmize Ihe performance of 
CONCERT. 
If rain is .. pecled w.lhin I hour. do nol apply CONCERT, or weed 
conllol may be decreased. 
Applicalions made during or immedialely following periods of abnor· 
mally cold wealher for soybeans may result in less than satisfactory 
wa:d control. 
Poor weed control may result from applications made to plants under 
stress from ahnormal hot or cold weather. groWing conditions such as 
drought or water· saturated soil, dlscas~, or nematode, inseci. or prior 
herbICide injury. Delay application unhl stress passes and weeds and 
soyhcans resume growth. Se ..... cr~ stress from conditions immcdialC:ly 
following application may also rc..'mll poor weed control. 
CULTIVATION 
A limely cultivation may be necessary to control suppressed weeds. 
weeds that were beyond the maximum size at the time of application. or 
weeds Ihat emerge afler an application or CONCEI!:I'. 
Do nOl cuhivate before, during, or wilhin 7 days after the applicalion. 
Cullivation may decrease weed conlrol by pruning rOOlS and placing 
lhe weed under Slress. 
The besllime ro cuhivale is approximalely 14 days afler application.

APPLICATION EQUIPMENT 
Many crops are highly sensitive 10 CONCERT and CONCERT + 
CLASSIC. All direct or indirect contacl (such as spray drift) with crops 
o!bet than soybeans should be avoided. 
GnMlnd AppUcatlOD: 
Broadcasl Application 
• Use 10-25 gallons of water per ICre. 
• Use flat fan nozzles al 25-60 psi. 
• Do not use flood, hollow cone, rain drop, whirl chamber, or con­
trolled droplet applicator (CDA) Iype nozzles. Excessive spray drift, 
or poor weed control may result. 
For proper spray coverage, adjust the boom and nozzle height accord­
ing to the specifications listed by the nozzle manufacturer. 
Band Application 
Fo, band application, use proportionately less spray mixture. 
Carefully calibrate the band applicator to r.at exceed the labl-Ied rate. 
Carefully follow the manufacture~s instructions for nozzle types (flat 
fan nozzles preferred), nozzle orientation, distance of the nozzles from 
the crop and weeds, spray volumes, calibration, and spray pressure. 
For additional information on row banders, see DuPont bulletin. 
"Application Accuracy Row Banders," 
.' 'rial Application 
Use nozzle types and arrangemenls thaI will provide for optimum 
spray distribution and maximum coverage at 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. 
ENVIRONMENTAL CONDmONS AND BIOLOGICAL ACTIVITY 
CONCERT rapidly inhibits the growth of susceptible weeds, reducmg 
weed competition hours after application. Leaves tum yellow 5·7 days 
after postemergence application, followed by death of Ihe weed's 
growing poin'. Susceptible plants are controlled in 7-21 days. De"h of 
leaf tissue will follow in some speci~s. while others will rer.!lin green 
but stunled and noncompetitive. 
CONCERT provides best postemergence results when applied to young, 
actively growing weeds. Degree of control and duration of effect 
depend on: application rale. weed spectrum. weed size, growing condi­
tions at and following time of treatment. soil moisture. precipitation, 
and spray adjuvants. Some weeds. such as h:mbsquarters. are more 
affected by stress than others. Delay application until stress passes and 
weeds start 10 grow again. Treating weeds under stress or large weeds 
may result in only partial control. Conditions that are conducive to 
healthy. actIvely growing plants optimize the performance of 
CONCERT. 
If rain is expected WIthin I h(lUf, do not apply CONCERT. or weed 
control may be drcrr3co<"d 
) . . ) _. 
\ 
Applications made during or immediately following periods of abnor­
mally cold weather for soybeans may result in less than sai:isfactory 
weed control. 
POOl weed control may r<.Sult from applications made to plants under 
stress from abnormal hot or cold weather, growing conditions such as 
drought or water-saturated soil, disease, or nemat'lde, insect, or prior 
herbicide injury. Delay application until stress passes and weeds and 
soybeans resume growth. Severe stress (rom conditions immediately 
following application may also result poor weed control. 
CULTIVATION 
.\ timely cultivation may be necessary 10 conlrol suppressed weeds, 
weeds that were beyond the maximum size al the time of application, or 
weeds that emerge after an application of CONCERT. 
• Do not cultivale before, during, or within 7 days after the application. 
• Cultivation may decrease weed control by pruning roots and placing 
lbe weed under stress. 
The besl time to cultivale is approximalely 14 days afler application.

Field Bioassay·· 
" When using CONCERT Herbicide. the term "FIELD CORN" is 
defined to include only that com grown for grain or silage, popcorn, and 
seed com relative to the Rotauonal Crop Guidelines section of this label. 
""Field Dioassay 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 bioassay will detect small quantities of CONCERT 
that can remam in the soil and could potentially injure rotational crops. 
A successful firld bioassay means growing to maturity a test strip of 
crop(s) intended for production the following year. The test strip should 
cross the whole field, including knolls and low areas. 
SPRAYER PREPARATION AND CLEANUP 
It is important Ihat spray equipmenl is clean and free of previous pesti­
cide deposits hefore using CONCERT, and then prop"rly cleaned out 
following application. aean all application equipmenl before applying 
CONCERT. Follow the cleanup procedures specified on the label of lhe 
product previously sprayed. If no cleanup procedure is provided, use the 
procedure Ihat follows. Immediately following applications of 
CONCERT. thoroughly clean all mixing and spray equipment to avoid 
applications to crops other than soylxans.
