GENERAL INFORMATION 
AC 3037571 AC 263499 provides burndown and residual 
control of many broadleaf and grassy weeds in soybeans. 
It can be applied to no-till soybeans as a burndown prior 
to planting. It may also be applied postemergence to 
Roundup ReadY" soybeans for season-long weed 
control. AC 3037571 AC 263499 is effective for control of 
difficult weeds common to no-till production, including 
marestail. 
Occasionally, internode shortening and/or temporary yel­
lowing of crop plants may occur following an AC 3037571 
AC 263499 application. These effects occur infrequently 
and are usually temporary. 
BURNDOWN WEED CONTROL (No-till soybeans and 
stale seedbed) 
Apply AC 3037571 AC 263499 for burndown of weeds in 
no-till soybeans. It may be applied prior to planting, or 
preemergence of any soybean variety (including Roundup 
Ready or non-Roundup Ready soybeans). Add 2,4-D to 
the spray tank for enhanced control of perennial weeds 
including marestail and hemp dogbane. 
ROUNDUP READY SOYBEANS (glyphosate resist­
ant) 
AC 3037571 AC 263499 may also be applied for poste­
mergence weed control in Roundup Ready soybeans. 
Apply AC 3037571 AC 263499 for general weed burn­
down and season-long control of broad leaf and grassy 
weeds. 
For season-long control of grasses, apply Prowl® 3.3 EC 
herbicide prior to planting soybeans. Prowl 3.3 EC will 
also enhance control of waterhemp. A postemergence 
application of AC 3037571 AC 263499 will control any 
escape weeds and provide season-long control of most 
broadleaf and grass weeds. 
When mixing AC 303757/AC 263499 with 2,4-D or 
Prowl 3.3 EC, always use in accordance with the more 
restrictive label limitations and precautions. No label 
dosage rates should be exceeded. This product can not 
be mixed with any product containing a label prohibition 
against such mixing. 
When organophosphate (such as chlorpyrifos) or carba­
mate insecticides are tank-mixed with AC 303757/AC 
263499 temporary injury may result to the treated crops.

NOTE: DO NOT apply AC 303757/AC 263499 herbi­
cide postemergence to non-glyphosate­
resistant soybeans. 
FALL APPLICATIONS IN A PLANNED SEQUENTIAL 
PROGRAM ON ROUNDUP READY" SOYBEANS 
Apply AC 303757/AC 263499 after fall harvest and prior 
to ground freeze-up in the winter. Fall applications of AC 
3037571 AC 263499 will control existing weeds and 
provide residual control of winter annual weeds and early 
spring germinating weeds in soybeans. Soybeans must 
be planted in the spring following the fall application of 
AC 303757/AC 263499. If weeds emerge in-season, 
other registered soybean products may be applied poste­
mergence for weed control. 
NOTE: For fall applications of AC 3037571 AC 263499 
adjust the rotational crop intervals by basing the interval 
on the date of soybean planting rather than the date of 
herbicide application. 
FALL OR SPRING BURN DOWN APPLICATION IN A 
PLANNED SEQUENTIAL PROGRAM WITH 
LIGHTNING'" HERBICIDE APPLIED TO 
CLEARFIELD' CORN (only in states of Kentucky, 
Tennessee, and south of Interstate 70 in Indiana). 
AC 303757/AC 263499 may be applied as a fall or spring 
burndown application prior to planting CLEARFIELD' 
corn and the use of Lightning herbicide in-crop to 
CLEARFIELD' corn. DO NOT apply AC 3037571 
AC 263499 to emerged CLEARFIELD' corn, or crop 
injury will occur. 
NOTE: DO NOT apply COUNTER'" CR insecticide or 
COUNTER'" 15G insecticide to acres treated with AC 
303757/AC 263499 preplant CLEARFIELD' corn or 
crop injury may occur. 
DO NOT plant wheat in the same year as application of 
AC 303757/AC 263499 followed by Lightning, unless at 
least 10 inches of rainfall or overhead irrigation has 
occurred between application of AC 3037571 AC 263499 
and planting of wheat. 
ATTENTION 
AVOID CONTACT OF AC 303757/AC 263499 WITH 
FOLIAGE OF DESIRABLE PLANTS, BECAUSE SEVERE 
INJURY OR PLANT DEATH MAY RESULT. 
AVOID DRIFr AC 303757/AC 263499 CARE MUST BE 
USED WHEN APPLYING THIS PRODUCT TO PREVENT 
INJURY TO DESIRABLE PLANTS AND CROPS. 
DO NOT allow the herbicide solution to drift onto desir­
able vegetation. Very small amounts of drift may cause 
injury or death to desirable crops or plants. The likelihood 
of injury occurring from the use of this product increases 
when winds are gusty. The risk of injury from this product 
increases when wind direction is constantly changing or 
during inversion conditions or other weather conditions 
that favor drift. Avoid applications using high spray pres· 
sure and high speed. These contribute to conditions that 
favor small spray droplets and drift.

MIXING INSTRUCTIONS 
BURNDOWN OR POSTEMERGENCE APPLICATIONS OF 
AC 303757/AC 263499 REQUIRE THE ADDITION OF A 
SURFACTANT lIt:l.Q FERTILIZER. 
I. SURFACTANTS: Use a non-ionic surfactant con­
taining at least 80% active ingredient. Apply the sur­
factant at the rate of 1 pint per 100 gallons of spray 
mixture (0.125% vlv of the spray mixture). Use only 
surfactants approved for application to growing 
crops. 
AND 
II. FERTILIZER: Include a fertilizer in the spray solu­
tion. Add spray grade ammonium sulfate at the rate 
of 8.5-17 Ibs. per 100 gallons of spray solution. Use 
the higher rate when weeds are under moisture or 
temperature stress. 
When mixing AC 303757/AC 263499, while agitating, 
add components in the following order: 
1) Fill spray tank 1/2 full with clean water. 
2) Add fertilizer. 
3) Add AC 3037571 AC 263499 and thoroughly mix. 
4) Add surfactant to the spray tank. 
5) While agitating, fill the remainder of the tank with 
water.

DRIFT CONTROL ADDITIVES 
Drift control additives may be included to either ground or 
aerial applications, When a drift control agent is used, 
read and carefully observe the precautionary statements 
and all other information appearing on the additive label. 
To avoid injury to sensitive crops, spray equipment used 
for AC 3037571 AC 263499 herbicide applications must 
be drained and thoroughly cleaned with water before 
being used to apply other products, 
When AC 3037571 AC 263499 is used in combination 
with another herbicide, refer to the respective label for 
rates, methods of application, proper timing, weeds con­
trolled, restrictions and precautions, Always use in accor­
dance with the more restrictive label restrictions and pre­
cautions, No label dosages should be exceeded, AC 
3037571 AC 263499 cannot be mixed with any product 
containing a label prohibiting such mixtures, 
SPRAYING INSTRUCTIONS 
DO NOT apply when winds are gusty, under low-level 
inversion conditions or under other conditions that favor 
drift, Maintain appropriate buffer zones between treated 
fields and adjacent desirable vegetation, Exposed leaves 
or other green tissue may be damaged or killed by drift 
from AC 303757/AC 263499, 
GROUND APPLICATIONS: 
Uniformly apply with properly calibrated ground equip­
ment in 10 or more gallons of water per acre, A spray 
pressure of 20 to 40 psi is recommended, 
To ensure thorough coverage, use a minimum of 20 
gallons of water per acre when applying AC 3037571 
AC 263499 to minimum or no-till crops, Use higher gol­
lonage for fields with dense vegetation or heavy crop 
residues, Adjust the boom height to ensure proper cover­
age of weed foliage (according to the manufacturer's rec­
ommendation), Use only fiat-fan nozzle tips for postemer­
gence applications, 
Avoid overlaps when spraying, 
AC 303757/AC 263499 APPLICATIONS WITH A LOW 
VOLUME SPRAYER 
AC 3037571 AC 263499 may be applied to soybeans with 
a low volume (Spra-Coupe type) sprayer, When applying 
AC 3037571 AC 263499 with a low volume sprayer, spray 
the weeds before they reach the maximum size listed in 
this label. Adequate control of weeds is dependent upon 
good spray coverage of the weeds, The sprayer must be 
calibrated to deliver the recommended spray volume and 
pressure to ensure adequate spray coverage of the 
weeds, 
When applying AC 303757/AC 263499 with a low 
volume sprayer, apply a minimum of 10 gallons per acre 
of spray solution with a nozzle pressure between 40-60 
psi for optimum coverage, Lower nozzle pressure will min­
imize the potential for drift to desirable vegetation, 
AERIAL APPLICATION 
Uniformly apply with properly calibrated aerial equipment 
in 5 or more gallons of water per acre, When applied 
5 
POSTEMERGENCE, the addition of a non-ionic surfactant 
AND fertilizer solution are required for optimum weed 
control. Apply a non-ionic surfactant at the rate of 0,125% 
v/v of spray solution AND ammonium su~ate at the rate of 
2,5 Ib/acre, (See instructions under APPLICATION 
INFORMATION - POSTEMERGENCE), 
To avoid injury to sensitive crops from drift, aerial applica­
tors must adhere to the following SPECIAL AERIAL USE 
DIRECTIONS AND PRECAUTIONS, 
• Nozzle height above ground must be a maximum of 10 
feet. 
• Nozzles must be pointed toward the rear of the aircraft, 
The downward angle of the nozzle should not be greater 
than 20 degrees, 
• To minimize wing-tip vortex roll, nozzles or spray boom 
must not be located any closer to end of wing or rotor 
than three-fourths the distance from the center of the 
aircraft, 
• Use a maximum spray pressure of 40 psi. 
• A buffer zone must be established between the area to 
be sprayed and sensitive crops, 
• DO NOT spray when wind velocity is greater than 5 
mph, Coarse sprays (larger droplets) are less likely to 
drift, 
Applicator is responsible for any loss or damage which 
results from spraying AC 3037571 AC 263499 in a manner 
other than recommended in this label. In addition, applica­
tor must follow all applicable state and local regulations 
and ordinances in regard to spraying, 
APPLICATION INFORMATION 
POSTEMERGENCE 
AC 3037571 AC 263499 is effective in controlling weeds in 
conservation tillage as well as in conventional production 
systems, Apply AC 303757/AC 263499 as a postemer­
gence treatment. Application timing should be based on 
weed size and not crop growth stage, Apply AC 
3037571 AC 263499 to crops and weeds that are actively 
growing, 
A non-ionic surfactant and a nitrogen-based fertilizer must 
be added to the spray solution for optimum weed control 
activity, See the ADJUVANTS section under MIXING 
INSTRUCTIONS for specific instructions, 
When AC 3037571 AC 263499 is applied postemergence, 
absorption will occur through both the roots and foliage, 
Susceptible weeds stop growing and either die or are not 
competitive with the crop, AC 3037571 AC 263499 not 
only controls many existing broadleaf and grass weeds 
when applied postemergence, it also provides control of 
susceptible weeds that may emerge after application, 
For maximum weed control, cultivate 7 - 10 days follow­
ing a postemergence AC 3037571 AC 263499 applica­
tion, This timely cultivation will enhance residual weed 
control, especially under dry conditions, 
AC 3037571 AC 263499 herbicide should be applied a 
minimum of one hour before rainfall or overhead irrigation,

Unusually cool temperatures (50· F or less) reduce photo­
synthesis and transpiration and thus reduce uptake, 
translocation, and efficacy of AC 3037571 AC 263499 
herbicide in weeds. 
If air temperature has been below 50· F for 10 or more 
hours, delaying an AC 3037571 AC 263499 application for 
48 hours after the temperature increases above 50· F, will 
improve weed control and reduce crop response. 
NO-TILLJMINIMUM TILLAGE AND DOUBLE 
CROP SOYBEANS 
AC 3037571 AC 263499 controls existing weeds and 
provides residual control of most weeds when applied 
early postemergence to soybeans in no-till or minimum 
tillage and double crop soybean production systems. The 
application may be applied either before or after emer­
gence of the crop. (Refer to the WEEDS CONTROLLED 
chart for weeds controlled and recommended weed size). 
The addition of Prowl'" 3.3 EC herbicide in a tank­
mixture with AC 303757/AC 263499 for burndown weed 
control will provide season-long control of grasses and 
enhance control of waterhemp. 
For improved burndown weed control, AC 303757/AC 
263499 may be tank-mixed with 2,4-0. Refer to the 2,4-0 
label for application rates and intervals between applica­
tion and planting.

tion:1 
All crops not listed elsewhere in this ROTATIONAL 
CROP GUIDELINE. 
1 Following forty months after an AC 303757/AC 
263499 application, and before planting any crop not 
listed elsewhere in the ROTATIONAL CROP GUIDE­
LINES, a successful field bioassay must be completed. 
The field bioassay consists of a test strip of the 
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, the intended 
rotational crop may be planted the following year. 
Sugarbeet production can be reduced when grown in 
soil conditions with a pH less than 6.S. If the field is lime 
to adjust pH prior to planting rotational crops not listed 
in the ROTATIONAL CROP GUIDELINE, apply the 
lime at least 1? months prior to planting the rotational 
crop. 
Use of AC 3037571 AC 263499 in accordance with label 
directions is expected to result in normal growth of rota­
tional crops in most situations; however, various envi­
ronmental and agronomic factors make it impossible to 
eliminate all risks associated with the use of this product 
and, therefore, rotational crop injury is always possible. 
EXCEPTIONS TO ROTATIONAL CROP 
GUIDELINE 
Wheat: Wheat may be planted 3 months following a 
AC 3037571AC 263499 application in areas east of inter­
state highway 1-35. 
Sweet corn and popcorn varieties: (States of Iowa, 
Illinois, Indiana, Ohio, Wisconsin, Minnesota and 
Tennessee only). Sweet corn and popcorn varieties may 
be planted the year following an application of AC 
3037571 AC 263499 . Some sweet corn and popcorn 
varieties may be injured when planted at less than 18 
months following an application of AC 3037571 AC 
263499 . Before planting sweet corn for processing, 
contact the processor company for information and rec­
ommendations regarding the tolerance of sweet corn vari­
eties planned for fields treated with AC 303757/AC 
263499 the previous year. DO NOT plant fresh market 
sweet corn varieties prior to 18 months after AC 
3037571 AC 263499 use. Before planting popcorn, 
contact the popcorn company for information and recom­
mendations regarding the tolerance of popcorn varieties 
planned for fields treated with AC 3037571 AC 263499 
the previous year. Since growing conditions, environmen­
tal conditions and grower practices are beyond the 
control of BASF, ALL RISKS AND CONSEQUENCES 
ASSOCIATED WITH PLANTING SWEET CORN OR

... 
POPCORN VARIETIES INTO FIELDS TREATED PRE­
VIOUSL Y WITH AC 303757/AC 263499 herbicide 
SHALL BE ASSUMED BY THE USER. 
Stunting and maturity delay or other adverse effects may 
result when sweet corn or popcorn are planted following 
AC 303757/AC 263499 use. 
Com inbred lines: Corn inbred seed lines may be 
planted the year following an application of AC 
3037571 AC 263499 . Several seed companies have 
tested a wide range of inbreds for sensitivity to AC 
303757/AC 263499 soil residues and have reported good 
crop safety. However, due to the proprietary nature of 
seed production, BASF has not been given access to the 
inbred data. 
Growers are directed to contact the seed company for 
information and recommendations regarding the planting 
of corn grown for seed in fields treated with AC 
3037571 AC 263499 the previous year. Since growing 
conditions, environmental conditions and grower prac­
tices are beyond the control of BASF, all risks and conse­
quences associated with planting seed corn inbreds into 
fields treated previously with AC 303757/AC 263499 shall 
be assumed by the user. 
Certain vegetable crops: (States of New Jersey, 
Virginia, North Carolina, South Carolina, Georgia, 
Alabama, Florida, Delaware, Maryland, 
Pennsylvania, Kentucky and Indiana only). The follow­
ing crops may be planted 18 months following the last 
application of AC 3037571 AC 263499 : bahiagrass, 
cabbage, cantaloupe, cucumber, Irish potato, onion, 
sweet potato transplants, sweet pepper transplants, 
tomato transplants, and watermelon. 
Barley: (States of Indiana, Ohio, Kentucky, 
Pennsylvania, New Jersey, Delaware, Virginia and 
Maryland only). Barley may be planted 4 months follow­
ing an AC 3037571 AC 263499 application in these 
states. 
PRECAUTIONS 
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 85 days between 
an application of AC 303757/AC 263499 and soybean 
harvest. 
AC 3037571 AC 263499 applications should be made 
before soybean bloom. 
Make only one application of AC 3037571 AC 263499 per 
soybean growing season. 
DO NOT graze or feed treated soybean forage, hay or 
straw to livestock.
