For broad spectrum control of grass and broadleafweeds in soybeans, apply TRI-SCEPT as a preplant incorporated 
trea:...-nent. 
After TRI-SCEPT is applied, some susceptible weeds emerge, growth stops, and then the weeds either die or are not 
cOIT'--?etitive with the crop. 
A timely cultivation may aid in the control of certain weeds or improve general weed control when adequate 
moisture is not received after application. Cultivation should be shallow. 
TRI-SCEPT reaches the growing points of susceptible weeds either by direct contact in the soil, or by root uptake 
and rapid translocation to the growing points. "Iberefore, adequate soil moisture is important for optimum 
TRI-SCEPT activity. The amount of rainfall or irrigation required following application depends on existing soil 
moisture, soil texture and organic matter content Sufficient water to moisten the soil to a depth of 2 inches is 
nonnally adequate. When adequate moisture is received after dry conditions, TRI-SCEPT will provide residual 
con:rol of susceptible genninating weeds; activity on esmblished weeds will depend on the weed species and the 
loc::tion of its root system in the soil. 
5 03/20101

A TRI-SCEPT preplant incorporated treabDent followed by a SCEPTER'" O.T.'" or Classic' postemergence 
treatment will control certain problem weeds. Use sequential treatments in recommended states only. 
Occasionally. internode shortening of soybean plants may be observed with TRI-SCEPT applications. This has no 
effect on soybean yields. 
Naturally occurring biotypes· of some of the weeds listed on this label may not be effectively controlled by this 
andlor other products with either the ALSI AHAS enzyme inhibiting mode of action or the mitotic inhibiting mode 
of action. Other herbicides with the ALS/AHAS enzyme inhibiting mode of action include the sulfonylureas (e.g., 
Accent', Basis', Classic. Concert', Exceed6 , Permit', Pinnacle', etc.), the sulfonamides (e.g., Broadstrike', etc.) and 
the pyrimidyl benzoates (e.g. , Staple', etc.). Herbicides with the mitotic inhibiting mode of action include the other 
dinitroaniline herbicides such as PROWL'" 3.3 EC, TREFLAN', TRIA'" HF and Sonolan'. If naturally occurring 
biotypes are present in a field which are resistant to one of the herbicides in this premix and are not controlled by 
the other mode of action herbicide in this premix, TRI-SCEPT should be tank-mixed or applied sequentially with an 
appropriate registered herbicide having a different mode of action to ensure control. 
* A weed biotype is a naturally occurring plant within a given species that has a slightly different, but distinct, 
genetic makeup from other plants. 
See your BASF representative for additional information. 
PRECAUTIONS: 
DO KOT apply sequential applications of SCEPTER"', SCEPTER'" 70DG, PURSUIT"', or PURSUIT'" DG the 
same year as a TRI-SCEPT application. 
DO NOT apply TRI-SCEPT postemergence to soybeans as crop injury may occur. 
DO KOT use TRI-SCEPT other than in accordance with the instructions set forth on this label. 
DO NOT use on crops other than soybeans. Crops other than soybeans, such as cotton, com, grain sorghum, rice 
and vegetables, may be injured by spray drift or other indirect contact with TRI-SCEPT. 
To avoid injury to sensitive crops from spray drift, follow all use directions and precautions in the SPRAYING 
INSTRUCTIONS section. 
To avoid injury to sensitive crops, spray equipment used for TRI-SCEPT applications must be drained and 
thoroughly cleaned with water before being used to apply other products to these crops. 
Apply TRI-SCEPT prior to July I in Use Region 3, as defined in the Use Area section of this label. 
There should be an interval of 90 days between the TRI-SCEPT application and soybean harvest. 
DO NOT graze or feed treated soybean forage, hay, or straw to livestock. 
Use of TRI-SCEPT herbicide in accordance with label directions is expected to result in normal growth of 
rotational crops in most situations; however, various environmental and agronomic factors make it impossible to 
eliminate all risks associated with the use of this product and, therefore, crop injury, is always possible. See the 
Rotational Crop Restriction section. 
Replanting: If replanting is necessary in a field previously treated with TRI-SCEPT, the field may be replanted to 
soybeans. Rework the soil no deeper than the treated zone. DO NOT apply a second treatment of TRI-SCEPT.

APPLICA TlON RATE 
Apply TRI-SCEPT at a rate of2.33 pints per acre. 
APPLICATION INSTRUCTIONS 
PREPLANT INCORPORATED APPLICATIONS: Apply TRI-SCEPT before planting and thoroughly 
incorporate. Incorporation implements should be set to thoroughly incorporate TRI-SCEPT into the top 2 inches of 
soil. A second pass must be made at an angle to the first pass to ensure thorough incorporation. PTO-driven 
equipment should be set to cut 2 inches deep and operated one time at 4 mph or less. Incorporate into the soil 
within 24 hours after application. 
TRI-SCEPT may be applied during land preparation up to 30 days prior to planting or immediately prior to planting 
in Use Region 1. For Use Region 2 and Use Region 3. TRI-SCEPT may be applied during land preparation up to 
45 days prior to planting or immediately prior to planting. Adequate moisture is required for activation of TRI­
SCEPT. 
If soybeans are planted on beds. apply and incorporate after bed formation using PTO-driven equipment or rolling 
cultivator. 
HERBICIDE COMBINATIONS 
TRI-SCEPT must be used only in accordance with the directions on this labeL 
In addition to those broadleaf herbicides specifically mentioned elsewhere in this label. TRI-SCEPT applications 
may be followed by one or more of the following herbicides: STATUS, Basagran'. Blazer, Cobra, Flexstar. 
Galaxy', Storm', Reflex, Roundup, or Roundup Ultra. DO NOT apply Roundup or glyphosate-containing products 
postemergence to soybeans that are not glyphosate-resistant. For sequential treatments with TRI-SCEPT and other 
products, a sufficient time period should occur between treatments to allow an appropriate assessment of weed 
control needs. 
Heavy infestations of some broadleaf weeds such as common ragweed and giant ragweed, which genninate deep in 
~e soil :ClOd may emerge at various times during the growing season, may require a cultivation or the application of 
a postemergence herbicide, such as a diphenylether (e.g., STATUS). for season long control. 
TRI-SCEPT may be followed by herbicides registered for postemergence grass control in soybeans. 
TRI-SCEPT Plus Trlfluralin or PROWL 3.3 EC Tank Mixture

TRI-SCEPT Plus Command 4EC Preplant Incorporated Tank Mixture 
Observe all precautionary statements on the Command 4EC label before using. Use sprayers equipped with nozzles 
that provide accurate and unifonn application. 
TRI-SCEPT plus Command 4EC preplant incorporated tank mixture may be used when heavy infestations of 
velvetleaf are anticipated. 
Apply 2.33 pints per acre of TRI-SCEPT plus 0.25 to 0.5 pint (4 to 8 oz.) per acre of Command 4EC to the soil 
surface and unifonnly incorporate. Refer to the Command 4EC label for incorporation instructions. DO NOT 
apply aerially or through irrigation systems. DO NOT apply this tank mixture to overly moist Or wet soils. 
NOTE: The use of an agriculturally approved drift reducing agent is required at spray volumes of 10 to 15 gallons 
per acre. 
Command 4EC is a volatile compound. Off-site movement of spray drift or vapors of Command 4EC can cause 
foliar whitening or yellowing of some plants. Prior to using Command 4EC, read and strictly follow all precautions 
and application instructions on the Command 4EC label. 
When applied as directed. tank mixrures of TRI-SCEPT plus Command 4EC control heavy infestations of velvetleaf 
as well as the weeds listed in the WEEDS CONTROLLED section of this label. Use the high rate of Command 
4EC when severe infestations of velvetleaf are anticipated. 
Follow all rotational crop restrictions on the TRI-SCEPT and Command 4EC labels. Always follow the most 
restrictive label. 
In the event of a crop loss due to weather conditions, soybeans can be replanted. DO NOT work the soil deeper than 
2 inches. 
TRI-SCEPT FoUowed by Roundup or Roundup Ultra 
(Glypbos8te-Resistant Soybeans Only) 
TRI-SCEPT may be applied preplant incorporated to Roundup Ready' soybeans for early season weed control and 
residual activity on broadleaf weeds and grass weeds. If weeds emerge later, Roundup or other glyphosate­
containing products may be applied postemergence for weed control. For sequential treatments, a sufficient time 
period should elapse between treatments to allow an appropriate assessment of weed control needs. 
Refer to the Roundup or other gi)--phosate-containing product labels for specific use recommendations, rates, and 
weeds controlled. 
Observe all precautions and limitations on the Roundup or other glyphosate-containing product labels. 
Note: DO NOT apply Roundup or other glypbosate-containing products postemergence to non glyphosate-resistant 
soybeans. 
MIXING INSTRUCTIONS 
Fill the spray tank one-fourth to one-half full with clean water or liquid fertilizer. While agitating add the required 
amount of product and then fill the remainder of the tank with water or liquid fertilizer. Maintain agitation while 
spraying to ensure a uniform spray mixture. 
When tank mixing TRI-SCEPT with recommended herbicides, add the TRI-SCEPT to the spray tank first and make 
sure it is thoroughly mixed before adding the other herbicide.

\ 
SPRAYING INSTRUCTIONS 
:-rOTE: DO NOT make applications when spray may be carried by wind to sensitive crops. Sensitive crops include 
leafy vegetables. sugarbeets. and cotton. Avoid overlaps when spraying. 
GROU~l) APPLICATIONS: 
Uniformly apply with properly calibrated ground equipment in 10 to 40 gallons of water. or 20 or more gallons of 
liquid fertilizer per acre. A spray pressure of 20 to 40 psi is recommended. 
DO NOT apply with ground equipment when wind velocity is greater than 10 mph. 
AERIAL APPLICATIONS: 
Uniformly apply with properly calibrated aerial equipment in 5 or more gallons of water per acre. 
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many 
equipment- and weather-related factors detennine the potential for spray drift. The applicator and the grower are 
responsible for considering all these factors when making decisions. 
The following drift management requirements must be followed to avoid off-target drift movement from aerial 
applications to agricultural field crops. 
I. The distance of the outermost nozzles on the boom must not exceed 34 the length of the wingspan or rotor. 
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 
degrees. 
\Vhere states have more stringent regulations. they should be observed. 
The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction 
Advisory Information presented below. 
INFORMATION ON DROPLET SIZE: 
The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to 
apply 'he largest droplets that provide sufficient coverage and control. 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 INVERSIONS). 
CONTROLLING DROPLET SIZE 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated 
flows produce larger droplets. 
• Pressure - Do not exceed the nozzle manufacturer"s recommended pressures. For many nozzle types, lower 
pressure produces larger droplets. When higher flow rates are needed. use higher flow rate nozzles instead of 
increasing pressure. 
• Number of Nozzles - Use the minimum number of nozzles that provide unifonn coverage. 
• Nozz.le Orientation - Orienting nozzles so that the spray is released paranel to the airstream produces larger 
droplets than other orientations and is recommended practice. Significant deflection from the horizontal will 
reduce droplet size and increase drift potential. 
• 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. Solid stream nozzles oriented 
straight back produce the largest droplets and the lowest drift.

) 
BOOM LENGTH 
For some use patterns, reducing the effective boom length to less than ~ of the wingspan or rotor length may further 
reduce drift without reducing swath width. 
APPLICATION HEIGHT 
Applications should not be made at a height greater than 10 feet above the top of the largest plants unless a greater 
height is required for aircraft safety. Making applications at the lowest height that is safe reduces exposure of 
droplets to evaporation and wind. 
SW ATH ADJUSTMEl'.'T 
When applications are made with a crosswind, the swath will be displaced downward. Therefore, on the up and 
downwind edges of the field, the applicator must compensate for this displacement by adjusting the path of the 
aircraft upwind. Swath adjustment distance should increase with increasing drift potential (higher wind, smaller 
droplets, etc.). 
WIND 
Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, including droplet size and 
equipment type, detennine drift potential at any given speed. Application should be avoided below 2 mph due to 
variable wind direction and high inversion potential. NOTE: Local terrain can influence wind patterns. Every 
applicator should be familiar with local wind patterns and how they affect spray drift. 
TEMPERATURE AND HUYlIDITY 
When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for 
evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 
TEMPERATURE INVERSIONS 
Applications should not occur during a temperature inversion because drift potential is high. Temperature 
inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. 
This cloud can move in unpredictable directions due to the light variable winds common during inversions. 
Temperature inversions are characterized by increasing temperatures \\ith altitude and are common on nights with 
limited cloud cover and light to no wind. They begin to fonn 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. 
SENSITIVE AREAS 
The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas, 
bodies of water. known habitat for threatened or endangered species, or non-target crops) is minimal (e.g. when 
wind is blowing away from the sensitive areas). 
Applicator is responsible for any loss or damage which results from spraying TRI-SCEPT in a manner other than 
recommended in this label. In addition, applicator must follow all applicable state and local regulations and 
ordinances in regard to spraying 
APPLICATIONS WITH LIQUID FERTILIZERS 
TRI-SCEPT can be applied in liquid fertilizers, alone or in combination with PROWL 3.3 EC, trifluralin, or 
Command 4EC. Follow all TRI-SCEPT label recommendations regarding incorporation, timing of application, 
special instructions and precautions. Apply treatments in 20 or more gallons of liquid fertilizer per acre with ground 
equipment. 
All individual state regulations relating to fluid fertilizer mixing, registration, labeling and application are the 
responsibility of the individual andior company selling.the TRI-SCEPTlliquid fertilizer mixture.

LIQUID FERTILIZER COMPATIBILITY DETERMINATIONS 
If a liquid fertilizer and herbicide(s) mixture separaleS in the spray tank, clogged equipment and uneven application 
can result, which can cause poor weed control and crop injury. Always predetermine the compatibility of TRI· 
SCEPT alone or with PROWL 3.3 EC, trifluraJin. or Command 4EC in the specific liquid fertilizer to be used 
according to the following directions: 
I. Add I pint of fertilizer to each of 2 one·quart jars. 
2. Add 112 teaspoon of adjuvant to one jar. 
3. (a) When using TRI·SCEPT alone, add to each jar the correct amount of TRI·SCEPT as specified in the 
following table. 
(b) When using TRI·SCEPT pbs PROWL 3.3 EC, trifluralin or Command 4EC, first add the specified 
quantity of TRl·SCEPT. theu add the co=t amount of PROWL 3.3 EC, trifluralin or Command 4EC. 
4. Close both jars and shake thoroughly for 10 ,",conds. Let them stand for 30 minutes and then observe the 
results. Look for signs of separation. an oily layer or globules, sludge, flakes or other precipitates. 
5. Determine compatibility 
(a) If the mixture without adjuvant does not separate, use this mixture in your spray tank. 
(b) If the mixture with adjuvant does not separate, but the one without adjuvant separates, use the adjuvant 
mixture in your spray tank .. -\dd the adju\"ant to the liquid fertilizer as directed on the manufacturer's label. 
(c) If either mi,mre separates, but mixes readily with shaking, the mixture can be used providing good agitation 
is maintained in the 5pray tank. 
(d) If separation of the mixture occurs, and agitation and/or adjuvant does not correct the problem, DO NOT 
use the herbicide(s) in that specific liquid fertilizer.

All individual state regulations relating to dry bulk fertilizer blending, registration, labeling, and application are the 
responsibility of the individual andlor company selling the TRI-SCEPT/dry bulk fertilizer mixture. 
A minimum of 200 pounds and a maximum of 450 pounds of dry bulk fertilizer impregnated with the recommended 
amount of TRI-SCEPT must be applied per acre. 
DO NOT impregnate TRI-SCEPT onto coated ammonium nitrate or limestone because these materials will not 
absorb the herbicide. Dry fertilizer blends containing mixtures of ammonium nitrate or limestone may be 
impregnated with TRI-SCEPT. A minimum of 200 pounds of impregnated dry bulk fertilizer, excluding the weight 
of ammonium nitrate or limestone, must be applied per acre.

fertilizer blender equipped with suitable spray equipment. Spray nozzles must be placed to provide uniform 
coverage of TRI-SCEPT onto the fertilizer during mixing. 
If trifluralin or PROWL 3.3 EC is to be combined with TRI-SCEPT prior to impregnation, premix the trifluralin or 
PROWL 3.3 EC with an equal volume of water before adding it to the TRI-SCEPT. DO NOT mix undiluted 
trifluralin or PROWL 3.3 EC with TRI-SCEPT. 
Apply the TRI-SCEPT/dry bulk fertilizer mixture with an accurately calibrated dry fertilizer spreader. The TRI­
SCEPT/dry bulk fertilizer mixture must be spread uniformly on the soil surface. Uneven spreading can cause poor 
weed control and crop injury.
