c. Either retain the spray drift statements that appear on 
the proposed labeling for this product or update the Spray 
Drift Section so it complies with language recommended by the 
Industry - EPA Spray Drift Task Force. 
For your information, the following is the initial paragraph 
for the spray drift management p~atements that appear on a 
rece~tly registered pesticide product: 
SPRAY DRIFT 
Avoid spray drift. Do not apply when weather conditions 
may cause drift. Do not allow this product to drift on 
to non-target areas. Drift may result in illegal 
residues or injury to adjacent crops and vegetation. To 
avoid spray drift, DO NOT apply aerially when wind speed 
is greater than 10 mph or during periods of temperature 
inversions. Use of larger droplet size will also reduce 
spray drift. 
d. since the section for use of an either an Adjuvant or a 
Surfactant is ahead of all of the Tank Mixtures directions, 
the label still implies that surfactants can be used with 
Roundup Ultra or Touchdown in contradiction to their label

GENERAL INFORMATION 
STRUCTURE residual herbicide applied as an early preplant, preplant incorporated. or 
preemergence treatment, provides early season and residual control of broadleaf and grass weeds 
in Roundup Ready soybeans. STRUCTURE reduces competitive effects from weeds during the 
first weeks after soybean planting. If weeds emerge later. Roundup Ultra should be applied 
postemergence in a sequential program to maintain weed control. 
After STRUCTURE is applied, some susceptible weeds may emerge. However, growth then 
stops and the weeds either die or are not competitive 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. 
STRUCTURE 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. Therefore, adequate soil 
moisture is important for optimum activity of STRUCTURE. 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 normally 
adequate. If adequate moisture is not received within 7 days after treatment, then a cultivation or 
postemergence herbicide application may be needed to improve weed control. When adequate 
moisture is received after dry conditions, STRUCTURE will provide residual control of 
susceptible germinating weeds; activity on established weeds will depend on the weed species 
and the location of its root system in the soil. 
Occasionally, internode shortening of soybean plants may be obser .. ed with STRUCTURE 
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 and/or other products with either the ALS! 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~, 
Exceed~, 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 herbicide, TREFLANTM, TRI-4" HF 
herbicide and Sonalan™. 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, STRUCTURE 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.

) 
MIXING INSTRUCTIONS 
When water is used as the carrier, first fill the spray tank one-fourth to one-half ful\ with clean 
water. While agitating, add the required amount of STRl'CTURE. Fill the remainder of the tank 
with clean water. An antifoaming agent may be added to the tank if needed. Maintain agitation 
while spraying to ensure a uniform spray mixture. 
When tank-mixing STRUCTURE with recommended herbicides, add the other herbicides and 
adjuvants in the fol\owing order wrule agitating. Thoroughly mix each ingredient before adding 
the next ingredient. 
I. Fill spray tank 114 to 112 full with clean water. 
2. Add soluble packet products and thoroughly mix. 
3. Add WP (wettable powder), DG (dispersible granule), DF (dry flowable) or LF (liquid 
flowable) formulations. 
4. Add aqueous solution products. 
5. Add STRUCTURE. 
6. Add other EC (emulsifiable concentrate) products. 
7. Add surfactant to the spray tank.. 
8. Add liquid fertilizer. 
9. While agitating, fill the remainder of the tank with water. 
When paraquat is included in a tank-mixture, add 8 ounces of non-ionic surfactant per 100 
gallons of spray mi'l.'tUre as the last ingredient in the tank. 
In areas v.ith very hard water, a compatibility agent may be added to the tank to ensure uniform 
dispersion of the spray mixture. 
To avoid injury to sensitive crops, spray equipment used t'Or STRUCTURE applications must be 
drained and thoroughly cleaned with water before being used to apply other products.

GROUND 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. Use higher gallonage for fields with dense vegetation 
or heavy crop residues. A spray pressure of20 to 40 psi is recommended. 
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 ~ the length of the 
wingspan or rotOL 
2. Nozzles must always point backward parallel with the air stream and never be pointed 
downwards more than 45 degrees. 
Where 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. 
INFORMA nON ON DROPLET SIZE: 
The most effective way to reduce drift potential is to apply large droplets. The best drift 
management strategy is to apply the 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. 
12 8/98 
I

• 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. 
• "lumber of Nozzles - Use the minimum number of nozzles that provide uniform coverage. 
• "lozzle Orientation - Orienting nozzles so that the spray is released parallel 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. 
• "lozzle 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_-\TH ADJUSD.1ENT 
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.). 
wp'-l) 
Drift potential is lowest berween wind speeds of 2-10 mph. However, many factors, including 
droplet size and equipment type, determine 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. 
TEMPERA TORE AND HUMIDITY 
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. 
TEMPERA TORE 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 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 
13 8/98

) 
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 moyes 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. 
SENSITI\ 'E 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 STRUCTURE 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. 
APPLICATION IN FERTILIZERS 
) APPLICATIONS IN LIQUID FERTILIZERS 
) 
STRUCTURE can be applied in liquid fertilizers. Follow all STRUCTURE label 
recommendations regarding incorporation, timing of application, special instructions and 
precautions. For other STRUCTURE tank mix partners, refer to the individual product labels for 
specific recommendations for using these products with liquid fertilizers. Apply treatments in 20 
or more gallons of liquid fertilizer per acre with ground equipment. Maintain continuous 
agitation in the spray tank to prevent separation. To prevent clogging, use only flood nozzles 
with no nozzle screens . 
. -'1.11 individual state regulations relating to fluid fertilizer mixing, registration, labeling and 
application are the responsibility of the individual andlor company selling the 
STRUCTUllilliquid fertilizer mixture. 
) LIQUID FERTILIZER COMPATIBILITY DETERMINATIONS 
If a liquid fertilizer and herbicide(s) mixture separates in the spray tank, clogged equipment and 
uneven application can result, which can cause poor weed control and crop injury. .-\lways 
predetennine the compatibility of STRUCTURE in the specific liquid fertilizer to be used 
according 10 the following directions: 
J. Add 1 pint offertilizer to each of2 one-quart jars. 
2. Add 1/2 teaspoon of adjuvant to one jar. 
3. Add to each jar the correct amount of STRUCTURE as specified in the table below. 
4. Close both jars and shake thoroughly for 10 seconds. 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. Add the adjuvant to the liquid fertilizer as 
directed on the manufacturer's label. 
(c) If either mixture separates, but mixes readily with shaking, the mixture can be used 
providing good agitation is maintained in the spray tank. 
(d) If separation of the mixture occurs, and agitation and, or the addition of 
adjuvant/compatibility agent does not correct the problem, DO NOT use the herbicide(s) 
in that specific liquid fertilizer.

) APPLICATIONS WITH DRY BULK FERTILIZERS 
) 
STRUCTURE may be impregnated on dry bulk fertilizers. When applied as directed. 
STRUCTURE/dry bulk fertilizer mixtures provide weed control equal to that provided by the 
same rates of STRUCTURE applied in water or liquid fertilizer. 
Apply STRUCTURE/dry bulk fertilizer mixtures only with ground equipment. 
All individual state regulations relating to dry bulk fertilizer blending, registration, labeling, and 
application are the responsibility of the individual and/or company selling the STRUCTh"REIdry 
bulk fertilizer mixture. 
A minimum of 200 pounds and a maximum of 450 pounds of dry bulk fertilizer impregnated 
with the recommended amount of STRUCTURE must be applied per acre. 
DO NOT impregnate STRUCTURE 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 STRUCTURE. A minimum of 200 pounds of 
impregnated dry bulk fertilizer, excluding the weight of ammonium nitrate or limestone, must be 
applied per acre. 
,) Apply STRUCTURE at the rate of 3 pints per acre. Use the following table to determine the 
amount of STRUCTURE to be impregnated on a ton of dry bulk fertilizer based on the rate of 
fertilizer which will be applied per acre.

APPLICATION INSTRUCTIONS 
STRUCTURE may be used in Roundup Ready soybeans grown in conventional, minimum-, or 
no-till systems. STRUCTURE may be applied early preplant or preplant incorporated up to 15 
days before planting. Preemergence applications may be made during or after planting but 
before the crop cracks the soil surface. DO NOT apply postemergence (or at cracking) to 
soybeans. 
Adequate soil moisture is required for optimum activity of STRUCTURE. If sufficient rainfall 
or irrigation to activate STRUCTURE is nO! received within 7 days after application, a thorough 
shallow tillage or cultivation, or a postemergence herbicide treatment, (as appropriate to the 
tillage system), is recommended to enhance weed control. 
PREPLANT APPLICATIONS INCLUDING BURNDOWN 
Surface apply STRUCTURE up to 15 days before planting. For enhanced burndown of existing 
vegetation in no-till or reduced tillage systems, STRUCTURE may be applied in tank mix with, 
or following, either 2,4-0, Roundup Ultra.. Touchdown, or Gramoxone Extra. Refer to the 
respective product labels for rates, . methods of application, proper timing, weeds controlled, 
restrictions, and precautions. 
PREPLANT INCORPORATED APPLICATIONS 
Apply STRUCTURE before planting and incorporate uniformly into the top I to 2 inches of soil. 
STRUCTURE may be applied immediately before planting or up to 15 days prior to planting. 
Incorporate within 7 days after application. If soybeans are planted on beds, apply and 
incorporate after bed formation using PTO-driven equipment or rolling cultivator. 
PREEMERGE~CE APPLICATIONS 
SURFACE APPLICATIONS MADE BEFORE PLANTING 
STRUCTURE may be surface applied up 10 15 days before planting, both north and south of 
Interstate 1-80. 
SURF ACE APPLICATIONS MADE AFTER PLANTING 
STRUCTURE may be surface applied up to 2 days after soybean planting (before crop 
emergence) south of Interstate 1-80. 00 NOT APPLY STRUCTURE AFTER SOYBEAN 
PLANTING North ofInterstate 1-80, except in the states ofIndiana, Ohio, and Michigan. 
Note: Plant soybeans at least one inch deep and adjust planters to ensure adequate seed coverage. 
HERBICIDE COMBINATIONS 
For conservation tillage systems, STRUCTURE may be tank mixed with 2,4-0, Roundup Ultra, 
Touchdown, or Gramoxone Extra to kill existing vegetation. 
STRUCTURE must be used only in accordance with the directions on this label. Always follow 
the more restrictive label limitations and precautions when using tank mixes.

HERBICIDE COMBINATIONS FOR BURNDOWN 
IN CONSERVATION TILLAGE SYSTEMS 
For bumdown applications in conservation tillage systems: 
• add an adjuvant or a surfactant to the spray mixture, ANO 
• a nitrogen-based fertilizer at 1-2 qtJacre, or ammonium sulfate (spray grade) at 2.5lbs/acre 
• ensure thorough coverage using a minimum of 10 gallons of water per acre, with a higher 
gallonage for fields with dense vegetation or heavy crop residues 
• use appropriate nozzles to ensure thorough coverage 
• use ground equipment only. 
Adjuvant or Surfactant: 
Use either a methylated seed oil concentrate (e.g., SUN-IT IF") or a crop oil concentrate at 1% 
v/v (1 gallon per 100 gallons of spray mixture), or a nonionic surfactant (containing at least 80% 
active ingredient) at 0.25% v/v (1 quart per 100 gallons of spray mixture). 
Tank Mixtures with 2,4-D 
2,4-0 may be used with STRUCTURE alone or in combination with other STRUCTURE ta:Jk 
mixes prior to planting for control of some annual broadleaf weeds. Use the follo\\ing rates of

Tank Mixtures with Roundup Ultra or Touchdown 
l~ When applied early preplant or preemergence, Roundup Ultra or Touchdown may be mixed with 
~ STRUCTURE for control of weeds common to no-till production. Roundup Ultra Qr 
(j Touchdown will aid in the burndown of existing weeds, while STRUCTURE controls noo­
emerged weeds and some emerged weeds. 
The rate of Roundup Ultra or Touchdown, for tank mixes with STRUCTURE is the same as t!le 
rate of these products when used alone. 
Observe all precautions and limitations on the Roundup Ultra or Touchdown product labels.

) 
) 
) 
) 
Tank Mixtures with Gramoxone Extra 
Gramoxone Extra, at 1.5 to 2.5 pints per acre, may be used with STRUCTURE alone or in 
combination with other tank mixes for the control of certain emerged grasses and broad leaf 
weeds. Use the 2.5 pint rate if weeds are 4 to 6 inches tall. Weeds over 6 inches may not be 
controlled with this trealment. Apply up to 14 days before, during or immediately after planting. 
When Gramoxone Extra is included in a tank mixture, add a nonionic spreader surfactant at a rate 
of 8 fl. oz. per 100 gallons of spray mixture as the last ingredient in the tanle 
Gramoxone Extra will control most annual emerged weeds and suppress many emerged 
perennials. Refer to the Gramoxone Extra label for specific use recommendations and weeds 
controlled. 
Observe all precautions and limitations on the Gramoxone Extra label. 
STRUCTURE FOLLOWED BY ROUNDUP ULTRA 
IN A SEQUENTIAL PROGRAM 
STRUCTURE may be applied early preplant, preplant incorporated, or preemergence to 
Roundup Ready soybeans for early season weed control and residual activity on broadleaf weeds 
and grass weeds. If weeds emerge later, Roundup Ultra may be applied postemergence for weed 
control. Apply Roundup Ultra postemergence at 1 pint per acre when weeds are 1-3 inches, and 
prior to canopy closure. The addition of ammonium sulfate (spray grade) at 2.5 Ibs per acre, is 
recommended. For sequential treatments, a sufficient time period should elapse between 
treatments to allow an appropriate assessment of weed control needs. 
Note: DO NOT apply Roundup Ultra postemergence to soybeans that are not glyphosate­
resistant. Avoid conta.:t with all non glyphosate-resistant plants on which treatment is not 
intended, since se'·ere injury or destruction will result from drift, splash, or other contact with 
Roundup Ultra. 
Observe all precautions and limitations on the Roundup Ultra product label.

ROT A TlONAL CROP GUIDELINES 
The following rotational crops may be planted after applying STRUCTURE in soybeans at the 
recommended rate: 
I. Anytime: Soybeans 
2. Four months: Wheat 
3. Nine and one-half months: IMI-CORN'" seed hybrids'; Field com (non IMI-CORN seed 
hybrids) 
4. Eleven months: . Barley; Edible beans 
5. Eighteen months: Alfalfa; Grain sorghum; Oats; Pop com; Sweet com; Peas 
6. Twenty six months: Potatoes 
7. Forty months: Sugar beets'; Red table beets'; all crops not listed elsewhere m the 
ROTATIONAL CROP GUIDELINES'. 
, Contact your chemical dealer, seed supplier, or American Cyanamid to obtain information 
regarding the availability of imidazolinone tolerant (IMI-CORN) field com hybrids which are 
adapted to your area. 
, Following 40 months after a STRUCTURE application, and before planting sugar beets, red 
table beets, or any crop not listed elsewhere in the ROTATIONAL CROP GUIDELINES, a 
successful field bioassay must be completed. The field bioassay consists of a test strip of 
sugar beets (or the other intended rotational crop) planted across the previously treated field 
and grown to maturity. The test strip should include low areas and knolls, and include 
variations in soil such as type and pH. If no crop injury is evident in the test strip, sugar beets 
(or the other intended rotational crop) may be planted the following year. 
If the field is limed to adjust soil pH prior to planting sugar beets (or other rotational crops not 
listed in the ROTATIONAL CROP GUIDELINES), apply the lime at least 12 months prior to 
planting. 
PRECAUTIONS 
DO NOT use STRUCTURE other than in accordance with the instructions set forth on this label. 
DO NOT apply STRUCTURE postemergence to soybeans as crop injury may occur. 
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 
STRUCTURE. 
To avoid injury to sensitive crops, spray equipment used for STRUCTURE applications mlli"! be 
drained and thoroughly cleaned with water before being used to apply other products to these 
crops. 
Use of STRUCTURE 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 use of this product and, therefore, 
20 8/98

) 
rotational crop injury is always possible. For specific recommendations see the ROTATIONAL 
CROP GUIDELINES. 
Only rotational crops harvested at maturity may be used for feed or food. 
Replanting: If replanting is necessary in a field previously treated with STRUCTURE, the field 
may be replanted to soybeans. Rework the soil no deeper than the treated zone. DO NOT 
APPLY A SECOND TREATMENT OF STRUCTURE. 
In the event of a crop loss due to weather, soybeans can be replanted. DO NOT work the soil 
deeper than 2 inches. 
If soybeans are furrow irrigated, till the soil prior to planting winter wheat or barley. The beds 
should be broken up and the soil mixed with tillage equipment set to cut 4-6 inches deep. 
There should be an interval of at least 90 days between an application of STRUCTURE and 
soy bean harvest. 
DO NOT graze or feea treated soybean forage, hay or straw to livestock. 
Application of produru containing chlorirnuron ethyl (e.g., Classic, Canopy~, Concert, Gemini~, 
Lorox~ Plus, Preview.8, Pinnacle, Synchrony~, etc.), imazaquin (e.g., DETAIL~, SCEPTER~, 
SCEPTER~ 70 DG, SCEPTER~O.T.~, SQUADRON~, STEEL~, TRI-SCEPT~), imazethapyr 
(e.g., PURSUI~, PURSUI~PLUS EC, etc.), or flumetsulam (e.g., Broadstrike) the same year 
as labeled rates of STRUCTURE may increase the risk of injury to sensitive rotational crops. 
Consult labels for recommended uses of these products in combinations.
