Beacon®
GENERAL INFORMATION
Beacon is a selective herbicide applied after emergence of both crop and weeds for the control of
shattercane, sorghum-almum, johnsongrass, quackgrass, and many broadleaf weeds in field corn
grown for silage, grain, or seed and popcorn. Application may be made by ground or aerial equip-
ment to young, actively growing weeds. Refer to Tables for lists of weeds controlled by Beacon alone
and in tank mix combinations.
The level of weed control following Beacon application is dependent upon weed species, weed size
at application, and growing conditions. Weed control is better when ample soil moisture exists before
and after Beacon application than when the soil is dry and weeds are under stress from lack of
moisture.
Where reference is made to weeds partially controlled, partial control can mean either erratic control
from good to poor or consistent control at a level below that generally considered acceptable for
commercial weed control.
Growth of susceptible weeds is inhibited following application of Beacon. The leaves turn yellow
and/or red after several days followed by death of the growing point and complete plant death occurs
7-30 days after Beacon application depending upon weed species and growing conditions. Weeds not
completely killed by Beacon are often stunted and are less competitive to corn. Beacon reaching the
soil during a postemergence application provides preemergence control of certain weed species.
This herbicide controls weeds by inhibiting a biochemical process which produces certain essential
amino acids necessary for plant growth. The inhibited enzyme system is acetolactate synthase (ALS).
Occurrence of ALS-resistant weed biotypes can be prevented or delayed by using this product in
sequence or in tank mixtures with other herbicides having a different mode of action, and by using
some form of mechanical control or a herbicide with a different mode of action to control weed
escapes before they set seed. Both modes of action should provide acceptable control of the specific
weed if applied alone at the rates used in tank mixture.
Beacon application at labeled rates rarely causes corn injury. When injury occurs, it is generally of
short duration and yields are not affected.
PRECAUTIONS
Follow the precautions listed below to reduce chances for crop injury and/or to avoid reduced weed
control:
11. Field Corn: Apply either a single postemergence Beacon application at the standard use rate
(0.76 oz./A) or the initial application of a split postemergence application (2 applications of
0.38 oz./A) over-the-top directed or semi-directed when free-standing field corn height is
between 4 and 20 inches. Corn plants less than 4 inches tall may be more susceptible to injury.
The second Beacon application of the split must be applied directed with drop nozzles when
corn is between 20 inches tall and before tassel emergence.
12. Beacon should not be applied if corn shows severe stress or injury due to drought, cold
weather, hail, flooding, compacted soil, saturated soil conditions, disease, insect damage,
nutrient deficiency, previously applied herbicides or other causes.
13. If irrigation is necessary following application, delay for 24 hours to minimize potential injury,
particularly on coarse-textured soils.
14. a. If a “normal� or IT* corn hybrid (not an IR or IMR* hybrid) is planted and Dyfonate®,
Lorsban®, Thimet®, or other organophosphate insecticide is applied at planting or before
applying Beacon, temporary injury may occur following the Beacon application. Do not
apply Beacon if this corn crop was previously treated with Counter® 15G (any application
method) or Counter CR® applied in-furrow at planting or over the row at cultivation, as
severe crop injury may occur. Application of Beacon to corn previously treated with labeled
rates of Counter CR applied in a surface band or T-band (in front of press wheel) at plant-
ing time, may result in crop injury. Syngenta will not be held responsible for losses or
damage resulting from such use.
*IT � Corn with enhanced imidazolinone herbicide tolerance.
*IR/IMR � Corn with enhanced imidazolinone herbicide resistance.
b. If an IR or IMR corn hybrid is planted, organophosphate insecticides, including terbufos
(Counter), can be applied at any time according to label directions without increasing the
likelihood of injury to those hybrids. Note: The interaction between organophosphate
insecticides and Beacon is completely overcome by corn hybrids with IR or IMR designa-
tions, but not by IT hybrids; i.e., IT hybrids should be considered like “normal� hybrids with
regard to this interaction.
15. Do not make a foliar postemergence or soil application of any organophosphate insecticide
within 10 days before or 7 days after a Beacon application, or severe crop injury may occur.
16. Beacon may be applied to all field corn hybrids except the few that are classified by Syngenta
as potentially susceptible to injury following Beacon application. Consult your chemical
dealer, seed supplier, or Syngenta representative for a current listing of field corn hybrids
classified as “potentially susceptible� to Beacon.
Beacon®
17. Popcorn and Seed Corn: Beacon can be applied directed or semi-directed to popcorn and
inbred lines of field corn; however, all inbred lines and all popcorn hybrids have not been
tested for sensitivity to Beacon nor does Syngenta have access to all seed company data.
Therefore, inbred lines and popcorn hybrids must be thoroughly tested for potential sensi-
tivity to Beacon before treating large acreages. To avoid crop injury, popcorn and inbred lines
should not be sprayed with over-the-top applications of Beacon; i.e., only semi-directed or
directed applications using drop nozzles when the popcorn or inbred plants are between 10
and 48 inches tall, and before tassel emergence.
18. Do not use Beacon on sweet corn or ornamental (Indian) corn.
19. Do not irrigate within 4 hours after Beacon application. Rainfall occurring within 4 hours
after Beacon application may reduce weed control.
10. Aphids or other insects infesting johnsongrass may move to the corn crop following control
of the johnsongrass with Beacon. The insects may transmit viral diseases to the corn resulting
in corn stunting, leaf discoloration, and yield loss. Virus-resistant corn hybrids and/or control
of the insects may be used to reduce the likelihood of disease development.
11. Crop competition with the weeds is particularly important for season-long control of target
grasses. Some regrowth may occur where the corn crop is not competitive. Best performance
can be obtained by following weed height and application recommendations listed later in
this label.
12. Decaying johnsongrass rhizomes have been shown to release compounds which can stunt
corn. The potential for corn stunting may be reduced if rhizome masses are broken up
through tillage prior to planting corn.
13. Do not apply Beacon in tank mixtures with Poast® or Poast Plus® herbicides, as grass control
is often reduced significantly and/or crop injury may occur.
14. Observe all precautions and limitations on the label of each product used in tank mixtures
with Beacon.
APPLICATION PROCEDURES
Ground Spray Equipment: Use stainless steel, aluminum, fiberglass, or polyethylene spray tanks. Spray
nozzles should be uniformly spaced and of the same size, and should provide accurate and uniform
application. Use spray nozzles which provide medium-coarse droplets to provide good coverage and
minimize drift.
To help assure accuracy, calibrate sprayer at the beginning of the season before use and recalibrate
frequently, especially when changing carriers. For ground application, use a minimum of 10 gals. of
water per acre. Higher volumes (e.g., 20 gals./A) should be used under severe weed infestations to
ensure adequate spray coverage. Always include crop oil concentrate or nonionic surfactant in the
spray mixture (see Mixing Instructions section which follows).
Use a pump with capacity to: (1) maintain 35-40 psi pressure at nozzles, and (2) provide sufficient
agitation within the tank to keep product in suspension. Lower pressures may be used with extended
range or low pressure nozzles. A centrifugal pump which provides propeller shear action for dispers-
ing and mixing the product is recommended. The pump should provide a minimum of 20 gals./
minute/100 gal. tank size circulated through correctly positioned sparger tubes or jets. Agitation
during both mixing and application is essential. Use screens to protect the pump and to prevent
nozzles from clogging. Screens placed on the suction side of the pump should be 16-mesh or coarser.
Do not place a screen in the recirculation line. Use 50-mesh or coarser screens between the pump and
boom, and when required, at the nozzles. Check nozzle manufacturer’s recommendations.
Good weed coverage with the spray mixture is essential for optimum weed control results. Observe
sprayer nozzles frequently during the spraying operation to ensure that the spray pattern is uniform.
Avoid any spray application under conditions when uniform coverage cannot be obtained or when
excessive spray drift may occur. To reduce spray drift, do not apply when winds are in excess of 10
mph. Allow adequate distance between target area and desirable vegetation to prevent drift to non-
target areas. Avoid spray overlap, because crop injury may result. Use a nozzle spacing and boom
height arrangement that avoid applying an excessive rate of Beacon directly over the corn rows.
Boom height for broadcast over-the-top application should be based upon the free-standing height
of the corn, not height above the soil surface; and should be at least 15 inches above the corn canopy.
Do not apply Beacon as a band application directly over the corn rows. Beacon must be applied post-
emergence over-the-top, directed, or semi-directed. If the corn canopy would prevent adequate weed
coverage, apply Beacon directed or semi-directed with drop nozzles even if the corn height is less than
20 inches. Beacon must be applied directed with drop nozzles when corn is between 20 inches tall and
before tassel emergence. Avoid all direct or indirect contact (such as spray drift) of Beacon with crops
other than those recommended for treatment on this label, since injury may occur.
Chemigation: Do not apply this product through any type of irrigation system.
Aerial Application: Apply Beacon in water using a minimum spray volume of 3 gals./A. Include a non-
ionic surfactant, i.e., X-77®, at 1 qt./100 gals. of spray mix (0.25% volume/volume) or a good quality
crop oil concentrate at no more than 2 pts./A. (See following Mixing Instructions.) Avoid application
under conditions where uniform coverage cannot be obtained or where excessive spray drift may
occur. Make applications at a maximum height of 10 ft. above the corn with low-drift nozzles at a
maximum pressure of 40 psi and wind speed not exceeding 10 mph to assure accurate Beacon appli-
cation within the target area.
Avoid application to humans or animals. Flagmen and loaders should avoid inhalation of spray mist
and prolonged contact with skin.
Do not apply Beacon by aerial application in New York state.
Beacon®
Recommendations to Avoid Spray Drift
As with all crop protection products, it is important to avoid off-target movement.
Do not allow spray from ground or aerial equipment to drift onto adjacent land or crops, as even small
amounts may injure sensitive plants. When drift may be a problem, take steps to reduce spray drift,
including:
� Do not spray if wind speeds are or become excessive. Do not spray if wind speed is in excess of
10 mph. If sensitive crops or plants are downwind, extreme caution must be used under all con-
ditions. Do not spray if winds are gusty.
� Use extreme caution when conditions are favorable for drift (high temperatures, drought, low
relative humidity), especially when sensitive plants are located nearby.
� Drift from aerial applications of the herbicide is likely to result in damage to sensitive plants
adjacent to the treatment site. This damage can occur at levels below the concentrations that can
be detected with chemical analysis.
� Do not apply when a temperature inversion exists. If an inversion condition is suspected, consult
with local weather services before making an application.
� Further reductions in drift can be obtained by:
1. Using nozzles that provide a uniform droplet size. Use nozzles that produce medium to
coarse droplets (250-400 microns VMD) that are less prone to result in spray drift.
2. Use flat fan nozzles. For example, Turbo Teejet, XR® Teejet, RF Raindrop®, or similar “low
pressure� nozzles are preferred.
3. Recalibrate sprayer using reduced spray pressures and increased spray volumes to produce
larger droplets when conditions favor drift.
4. Applying as close to target plants as practical to obtain a good spray pattern for adequate
coverage, while maintaining a minimum boom height of 15 inches over the crop canopy for
ground application.
IMPORTANT: Follow the correct mixing order on the label or the material may not mix properly. Poor
mixing may result in crop injury or poor product performance.
Mixing Instructions
11. Make sure the spray tank is clean before mixing. If it is contaminated with other materials, mix-
ing problems and/or clogging may occur, or injury to the crop may result.
12. Fill the spray tank 1/4 � 1/2 full with clean water and begin agitation.
13. Make certain that the agitation system is working properly and creates a rippling or rolling action
on the liquid surface. Maintain agitation throughout the mixing and spraying process.
14. Drop the required number of unopened water-soluble packets containing Beacon into the spray
tank while continuing agitation and allow time to fully disperse. Add any other products pack-
aged in water-soluble film to the tank at the same time. Allow the packets to completely dissolve
and the contents of the packets to fully disperse into the mix water. Important: Water-soluble
packets must always be the first material put into the spray tank after water.
15. While maintaining agitation, continue filling the spray tank. When the tank is 3/4 full, add any
tank mix partners. Add any water-dispersible granule or other dry formulations first, and allow
material to disperse. Then add any emulsifiable liquid formulation.
16. Follow by adding either (a) a nonionic surfactant with a minimum of 80% of the constituents
effective as a spray adjuvant (e.g., X-77), at the rate of 1 qt./100 gals. of spray volume (0.25% vol-
ume/volume) or (b) a petroleum- or vegetable-based crop oil concentrate containing not less than
12% emulsifier at 1-4 pts./A as specified on the oil adjuvant label. The concentration of the oil
adjuvant should not exceed 2.5% volume/volume. In addition to crop oil concentrate or nonionic
surfactant, liquid nitrogen fertilizer (28-34% nitrogen-ammonium form) may also be added at
2-4 qts./A. Instead of the liquid nitrogen fertilizer, spray grade ammonium sulfate may be used at
the rate of 2-4 lbs./A. Liquid nitrogen fertilizers or ammonium sulfate should not be used as a
substitute for crop oil concentrate or nonionic surfactant in the spray mixture. Do not use liquid
fertilizer as the spray carrier.
17. If AAtrex® (atrazine), Accent®, Banvel®, Buctril®, Buctril + atrazine, Clarity®, Marksman®,
Resource®, or 2,4-D is desired as a tank mix partner, add it next while continuing to agitate. When
Beacon is used alone or tank mixed with AAtrex (atrazine) or Accent, either crop oil concentrate
or a nonionic surfactant should be included, with or without liquid nitrogen fertilizer or ammo-
nium sulfate, as described in item 6 above. When Beacon is tank mixed with Resource, crop oil
concentrate is the recommended adjuvant but should be added at 1-2 pts./A. The addition of
liquid nitrogen fertilizer to the Beacon plus Resource tank mix can enhance the weed control
under dry weather conditions but may also increase the risk of crop injury (i.e., foliar burn). In dry
areas, crop oil concentrate is recommended instead of nonionic surfactant. Do not use crop oil
concentrate as the spray adjuvant when using tank mixtures with Banvel (more than 2 oz./A),
Buctril, Buctril + atrazine, Clarity (more than 2 oz./A), Marksman, or 2,4-D, i.e., use a nonionic
surfactant as the additive in tank mixtures containing those products. Do not add liquid nitrogen
when using Buctril, Buctril + atrazine or 2,4-D tank mixtures.
18. Complete filling the tank, maintaining sufficient agitation at all times to ensure surface action
until the spray tank mixture is uniform.
19. An anti-foaming agent may be added to reduce excessive foaming if needed.
10. Do not leave spray in the spray tank without continuous agitation. Always maintain agitation to
avoid separation and buildup of undesirable residues on the walls of the spray tank.
11. Make only sufficient spray mixture which can be used the day in which it will be sprayed. Beacon
will remain active in the spray solution for at least 48 hours.
Beacon®
Cleaning Equipment after Beacon Application
Because most crops other than corn are extremely sensitive to low rates of Beacon, special attention
must be given to cleaning equipment before spraying a crop other than corn. Mix only as much spray
solution as needed. Immediately after spraying, clean equipment thoroughly using this procedure:
1. Flush tank, hoses, boom, and nozzles with clean water.
2. Prepare a cleaning solution of 1 gal. of household ammonia per 50 gals. of water. Many com-
mercial spray tank cleaners may be used. Please request and read a copy of the Syngenta
brochure “Clean It Up! A Guide to Cleaning Your Sprayers� (SCP 175-00103-D 2/01) from your
local Syngenta representative for more information about proper tank cleaning procedures. Do
not use chlorine-based cleaners such as Clorox®.
3. Use a pressure washer to clean the inside of the spray tank with this solution. Take care to wash
all parts of the tank, including the inside top surface. If pressure washer is not available, com-
pletely fill the sprayer with the cleaning solution to ensure contact of the cleaning solution with
all internal surfaces of the tank and plumbing. Start agitation in the sprayer and thoroughly
recirculate the cleaning solution for at least 15 minutes. All visible deposits must be removed
from the spraying system.
4. Flush hoses, spray lines, and nozzles for at least one minute with the cleaning solution.
5. Dispose of rinsate from steps 1-3 in an appropriate manner. Spray the cleaning solution on
untreated corn or return to a rinsate tank for later use as make-up for spraying corn or use other
approved disposal.
6. Repeat steps 2-5.
7. Remove nozzles, screens, and strainers and clean separately in the ammonia solution after com-
pleting the above procedures.
8. Rinse the complete spraying system with clean water.
8. Note: If the tank is equipped with the proper number of correctly mounted 360° tank washing
nozzles which are attached to a dedicated rinsing system, less cleaning solution than a full tank
may be used. Use sufficient cleaning solution to thoroughly rinse all surfaces. Start the sprayer
agitation and recirculate the cleaning solution for at least 15 minutes. Flush the spray boom with
the cleaning solution. Repeat the rinsing procedure 1-2 times.
BEACON APPLIED ALONE
Grass and broadleaf weeds which are controlled following postemergence application of a full (0.76
oz./A) rate of Beacon are listed in Tables 1 and 2. If weeds other than those listed in Tables 1 and 2 are
anticipated, apply an appropriately labeled preplant, preemergence, or postemergence herbicide or
herbicide combination. Dual II MAGNUM®, Bicep II MAGNUM®, Bicep Lite II®, Bicep Lite II MAGNUM®,
Dual II MAGNUM + AAtrex are examples of herbicide treatments that can precede Beacon application.
Consult their respective labels for directions, precautions, and limitations before applying.
Beacon is packaged in water-soluble packets. One packet treats 2 acres at the standard use rate of
Beacon (0.76 oz./A). Apply a single application of Beacon at the standard use rate plus spray adjuvant
postemergence over-the-top, directed, or semi-directed when weed(s) are within the height range
specified for optimum control in Tables 1 and 2 and when the free-standing height of the field corn
is between 4 and 20 inches (minimum of 10 inches and only directed applications for inbred lines and
popcorn). Complete weed coverage is essential for optimum effectiveness of Beacon. To ensure good
spray coverage of the weeds and avoid potential crop injury, applications made after field corn is 20
inches tall (or exhibits more than 6 collars; V6, whichever comes first) should be directed or semi-
directed. Use drop nozzles for directed or semi-directed applications.
Seed Corn and Popcorn: Refer to Precaution 7 for application timing and other information.
Cultivation or split application of the standard use rate is recommended to control reinfestation that
may occur from regrowth or late germination of weeds and to improve weed control under dry con-
ditions. A waiting period of 7 days after Beacon application is recommended before making a culti-
vation or weed control may be reduced. Where shattercane is the target weed species, Beacon may
be applied at cultivation, but some regrowth of shattercane may occur. Apply Beacon ahead of culti-
vators; do not cultivate and then apply Beacon.
For optimum control of johnsongrass, cultivation or split application of the standard use rate (2 appli-
cations of 0.38 oz./A) is recommended to control reinfestation that may occur from regrowth.
Alternatively, apply 0.5 oz./A (3 acres/packet) at the first application, followed by an application of
0.25 oz./A (6 acres/packet) to control regrowth. The initial application of the split should be made
when the weed height is within the range specified for optimum control in Table 1 and when the free-
standing field corn height is between 4 and 20 inches. The second application of the split should be
made when the new weed growth is within the height range for optimum control listed in Table 1
and before tassel emergence.
After several years use of Beacon or other products for johnsongrass or shattercane control, stands of
these weeds may be substantially reduced. In fields with only seedling johnsongrass or with light
populations of shattercane, use a split application of Beacon by applying 0.5 oz./A (3 acres/packet) of
Beacon. Follow with a second application of 0.25 oz./A (6 acres/packet) to control rhizome john-
songrass or any shattercane which may germinate in later flushes.
The number of packets required to treat various acreages with a single or split Beacon application is
listed in Table 4.
Beacon®
Restrictions: To avoid possible illegal crop residues: (1) Do not graze or feed forage from Beacon-
treated corn to livestock within 30 days after application, (2) Do not harvest silage within 45 days
after application. (3) Do not harvest grain within 60 days after application. (4) Do not apply more
than the standard use rate per acre of Beacon. (5) Complete all Beacon applications to corn before
tassel emergence.

****Regrowth may occur. Control unacceptable regrowth with cultivation or the split application as
described above.
****Control of quackgrass is slower compared to other grass weed species.
****Partial control/suppression. Control is most effective under conditions favorable for weed growth
(i.e., adequate moisture, optimum temperature conditions). Do not use Beacon to control these
species if the weeds are subject to stress conditions (i.e., drought, cold temperatures, etc.), or are
not actively growing. Some other means of control should be used if infestations are severe.
****Certain biotypes of this weed species are known to be resistant to this and other ALS herbicides.
Where these ALS-resistant biotypes are known to exist, an appropriate registered herbicide,
active against that weed and with another mode of action, should be used alone or in tank mix-

***Partial control/suppression
***Certain biotypes of this weed species are known to be resistant to this and other ALS herbicides.
Where these ALS-resistant biotypes are known to exist, an appropriate registered herbicide, active
against that weed and with another mode of action, should be used alone or in tank mixture with
Beacon to control those biotypes.
***Crop oil concentrate plus liquid nitrogen fertilizer or ammonium sulfate are recommended as
spray adjuvants (refer to Mixing Instructions).
Beacon applied at 0.38 oz./A (4 acres/packet) will control the broadleaf weeds listed in Table 3 when
applied at the specified heights. Additionally, Beacon applied at 0.38 oz./A alone or in tank mixtures
will provide partial control/suppression of 4 to 12-inch shattercane, sorghum-almum, and seedling
johnsongrass under conditions favorable for weed growth (i.e., adequate moisture, no excessively
cool temperatures, etc.). If residual control of the broadleaf weed species is desired, or if prevailing
weather or soil conditions (cold temperatures, drought, etc.) are not favorable for weed growth, use
Beacon at the rates listed in Table 2, or in combination with other broadleaf herbicides as described
in the Beacon Tank Mix Combinations for Weed Control in Corn section.

BEACON TANK MIX COMBINATIONS FOR WEED CONTROL IN CORN
Beacon may be applied postemergence in tank mix combinations for improved control of various
weeds. For all tank mixtures of Beacon with other herbicides, refer to both labels for weeds controlled
and application information; and follow all restrictions and precautions on both labels.
Precautions for Tank Mix Combinations: (1) Beacon applied alone or in tank mixtures with
AAtrex/atrazine or Accent can be applied using either a nonionic surfactant or crop oil concentrate
with or without liquid nitrogen or ammonium sulfate. Refer to item 6 under Mixing Instructions for
information on rates of the various additives. (2) Do not use crop oil concentrate as the spray adju-
vant when using tank mixtures with Banvel (more than 2 oz./A), Buctril, Buctril + atrazine, Clarity
(more than 2 oz./A), Marksman, or 2,4-D. In mixtures with those products, use only a nonionic surfac-
tant with a minimum of 80% of the constituents effective as a spray adjuvant at the rate of 1 qt./100
gals. of spray volume (0.25% volume/volume). Do not add liquid nitrogen when using Buctril, Buctril
+ atrazine, or 2,4-D tank mixtures. (3) Do not apply Beacon in tank mixture with cyanazine (Bladex®
or Extrazine® II), or severe crop injury may result. (4) Syngenta does not recommend tank mixtures of
Beacon with other agricultural products not listed on this label due to the possibility of reduced con-
trol, crop injury, or other undesirable interactions. If Beacon is applied in tank mixtures with other
products, follow the most restrictive labeling requirements.
Beacon Standard Rate (0.76 oz./A, 2 acres/packet) Tank Mixtures
For postemergence control of weeds not controlled by Beacon used alone, tank mixtures with AAtrex
(atrazine), Accent, Banvel (dicamba), Buctril (bromoxynil), Buctril + atrazine, Clarity, Marksman, or
2,4-D may be used to increase the spectrum of control. When used in tank mixtures with these herbi-
cides, apply Beacon as recommended in this label and use the tank mix partner as directed on its label.
Beacon®
Beacon Reduced Rate (0.38 oz./A, 4 acres/packet) Tank Mixtures
For postemergence control of weeds in corn, Beacon applied at 0.38 oz./A will control/suppress the
weeds listed in:
� Table 5 when tank mixed with AAtrex (atrazine)
� Table 6 when tank mixed with Accent
� Table 7 when tank mixed with Banvel or Clarity
� Table 8 when tank mixed with Buctril
� Table 9 when tank mixed with 2,4-D
� Table 10 when tank mixed with Resource
Weeds should be actively growing at application. If weeds exceed the heights listed in Tables 5-10, use
either the standard 0.76 oz./A rate of Beacon alone, a tank mixture with the full rate of the tank mix
partner, or utilize another solution.
In addition to the tank mixtures described in Tables 5-10, Beacon at 0.38 oz./A may be tank mixed with
Buctril + atrazine at 1-2.5 pts./A or Marksman at 1-2 pts./A. Apply mixtures with Buctril + atrazine
when the corn is 4-12 inches tall and Marksman should be applied when the corn is 4-8 inches tall or
through the 5-leaf stage, whichever comes first. Refer to Table 3 of this label and the paragraph pre-
ceding that table, as well as the label of the mixing partner, for information on weeds controlled and
optimum weed heights. Under favorable growing conditions, these mixtures can prove particularly
useful for managing light infestations of shattercane along with various broadleaf weeds.
With all tank mixtures containing atrazine, application must be made before the corn exceeds 12
inches in height; and the total atrazine applied may not exceed 2.5 lbs. a.i./A per calendar year.
Control of relatively large cocklebur, sunflower, and velvetleaf may be antagonized somewhat by tank
mixtures of Beacon with atrazine containing products.
For all Beacon reduced rate tank mixtures, a preemergence herbicide (such as Dual II MAGNUM, Bicep
II MAGNUM, Bicep Lite II MAGNUM, Dual II MAGNUM + AAtrex) should be applied for grass control,
and will improve control of several of the weeds listed in Tables 5-10.
