PRODUCT INFORMATION
Product Description: This product is a postemergent, systemic herbicide with no soil residue activity. It
is generally non-selective and gives broad spectrum control of many annual weeds, perennial weeds,
woody brush and trees. It is formulated as a water-soluble liquid.
This product can be mixed with additives containing surfactant, buffering agents or pH adjusting agents. It
can be applied through most standard industrial or field-type sprayers after dilution and thorough mixing
with water or other carriers according to label instructions. Ammonium Sulfate can be used. See the
“MIXING” section of this label for instructions.
5
Time to Visible Symptoms: This product moves through the plant from the point of foliage contact to
and into the root system. Visible effects on most annual weeds occur within 2 to 4 days, but on most
perennial weeds may not occur for 7 days or more. Extremely cool or cloudy weather following treatment
may slow activity of this product and delay development of visible symptoms. Visible effects are a gradual
wilting and yellowing of the plant which advances to complete browning of above-ground growth and
deterioration of underground plant parts.
Stage of Weeds: Annual weeds are easiest to control when they are small. Best control of most
perennial weeds is obtained when treatment is made at late growth stages approaching maturity. Refer to
the annual, perennial, woody brush and trees rate tables for more information on controlling specific
weeds.
Always use the higher rate of this product per acre within the specified range when weed growth is heavy
or dense or weeds are growing in an undisturbed (non-cultivated) area.
Do not treat weeds under poor growing conditions such as drought stress, disease or insect damage, as
reduced weed control may result. Reduced results may also occur when treating weeds heavily covered
with dust.
Cultural Considerations: Reduced control may result when applications are made to annual and
perennial weeds that have been mowed, grazed, or cut, and have not been allowed to regrow to the
specified stage for treatment.
Rainfastness: Heavy rainfall or irrigation soon after application may wash this product off of the foliage
and a repeat application may be required for adequate control.
Spray Coverage: For best results, spray coverage should be uniform and complete. Do not spray weed
foliage to the point of runoff.
Mechanism of Action: The active ingredient in this product inhibits an enzyme, found only in plants and
microorganisms, that is essential to formation of specific amino acids.
No Soil Activity: Weeds must be emerged at the time of application to be controlled by this product.
Weeds germinating from seed after application will not be controlled. Unemerged plants arising from
unattached underground rhizomes or root stocks of perennials will not be affected by the herbicide and
will continue to grow.
Biological Degradation: Degradation of this product is primarily a biological process carried out by soil
microbes.
Annual Maximum Use Rate: Except as otherwise specified in the crop section of this label, the
combined total of all treatments must not exceed 6 quarts (6 pounds of glyphosate acid) of this product
per acre per year. For applications in noncrop sites or in tree, vine, or shrub crops, the combined total of
all treatments must not exceed 8 quarts (8 pounds of glyphosate acid) of this product per acre per year.
The maximum use rates stated throughout this products labeling apply to this product combined with the
use of all other herbicides containing glyphosate or sulfosate as the active ingredient, whether applied as
mixtures or separately. Calculate the application rates and ensure that the total use of this and other
glyphosate or sulfosate containing products does not exceed stated maximum use rate.
For Glyphosate Weed Resistance Management: Glyphosate, the active ingredient in this product, is a
Group 9 herbicide. Target site resistance to Group 9 herbicides is rare. Although rare in occurrence, any
weed population may contain plants naturally resistant to Group 9 herbicides. Weed species resistant to
Group 9 herbicides may be effectively managed utilizing another herbicide from a different Group or using
other cultural practices.
6
Weed resistance management recommendations for Group 9 herbicides are:
• Ensure optimum weed control by making applications at the right time (correct weed size) and
utilizing the specified label rate for the most difficult to control weed in your field.
• Base decisions on local needs and use the tool(s) necessary to obtain optimum weed control and
minimize weed escapes.
• Avoid tank mixtures that reduce this products efficacy (through antagonism) or which encourage the
use of rates of this product below the labeled rate.
• Scout treated weed populations for escapes 2 to 4 weeks after application.
• Report any incidence of repeated nonperformance of this product on a particular weed to the local
retailer or county extension agent.
NOTE: Use of this product in any manner not consistent with this label may result in injury to persons,
animals or crops, or other unintended consequences. Keep container closed to prevent spills and
contamination.
MIXING
Clean sprayer parts immediately after using this product by thoroughly flushing with water.
NOTE: Reduced results may occur if water containing soil is used, such as visibly muddy water or water
from ponds and ditches that is not clear.
Mixing with Water:
This product mixes readily with water. Mix spray solutions of this product as follows:
• Fill the mixing or spray tank with the required amount of water.
• Add the specified amount of this product near the end of the filling process and mix well. Use caution
to avoid siphoning back into the carrier source. Use approved anti-back-siphoning devices required
by state or local regulations.
• During mixing and application, foaming of the spray solution may occur. To prevent or minimize foam,
avoid the use of mechanical agitators, terminate by-pass and return lines at the bottom of the tank
and, if needed, use an approved anti-foam or defoaming agent.
Tank Mixing Procedure:
This product does not provide residual weed control. For subsequent residual weed control, follow a
label-approved herbicide program. Always predetermine the compatibility of labeled tank mixtures of this
product with water carrier by mixing small proportional quantities in advance.
It is the pesticide users responsibility to ensure that all products are registered for the intended use. Read
and follow the applicable restrictions and limitations and directions for use on all product labels involved in
tank mixing. Users must follow the most restrictive directions for use and precautionary statements of
each product in the tank mixture.
To the extent consistent with applicable law, buyer and all users are responsible for all loss or damage in
connection with the use or handling of mixtures of this product with herbicides or other materials that are
not expressly recommended in this labeling. Mixing this product with herbicides or other materials not
recommended on this label may result in reduced performance
Mix labeled tank mixtures of this product as follows:
1. Place a 20 to 35 mesh screen or wetting basket over filling port.
2. Through the screen, fill the spray tank one-half full with water and start agitation.
3. If ammonium sulfate is used, add it slowly through the screen into the tank. Continue agitation.
Ensure that dry ammonium sulfate is completely dissolved in the spray tank before adding other
products.
4. If a wettable powder is used, make a slurry with the water carrier, and add it SLOWLY through the
screen into the tank. Continue agitation.
7
5. If a flowable formulation is used, premix one part flowable with one part water. Add diluted mixture
SLOWLY through the screen into the tank. Continue agitation.
6. If an emulsifiable concentrate formulation is used, premix one part emulsifiable concentrate with two
parts water. Add diluted mixture slowly through the screen into the tank. Continue agitation.
7. Continue filling the spray tank with water and add the required amount of this product near the end of
the filling process.
8. If a surfactant is used, add it to the spray tank before completing the filling process.
9. Add individual formulations to the spray tank as follows: wettable powder, flowable, emulsifiable
concentrate, drift control additive, water soluble liquid.
Maintain good agitation at all times until the contents of the tank are sprayed. If the spray mixture is
allowed to settle, thorough agitation is required to resuspend the mixture before spraying is resumed.
Keep a by-pass line on or near the bottom of the tank to minimize foaming. Screen size in nozzle or line
strainers should be no finer than 50 mesh.

AERIAL SPRAY DRIFT MANAGEMENT
DRIFT MAY CAUSE DAMAGE TO ANY OTHER VEGETATION CONTACTED TO WHICH TREATMENT
IS NOT INTENDED. TO PREVENT INJURY TO ADJACENT DESIRABLE VEGETATION,
APPROPRIATE BUFFER ZONES MUST BE MAINTAINED.
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many
equipment and weather-related factors determine 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. These requirements do not apply to forestry applications,
public health uses or to applications using dry formulations.
1. The distance of the outer most nozzles on the boom must not exceed 3/4 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. Where states have more stringent regulations, they should be observed.
The applicator must be familiar with and take into account the information covered in the Aerial Drift
Reduction Advisory.
Aerial Drift Reduction Advisory
Importance of 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
Inversion”).
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 Use the lower spray pressures recommended for the nozzle. Higher pressure reduces
droplet size and does not improve canopy penetration. 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 uniform coverage.
• Nozzle Orientation Orienting nozzles so that the spray is released backwards, parallel to the
airstream, will produce larger droplets than other orientations. 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 larger droplets than other nozzle types.
• Boom Length For some use patterns, reducing the effective boom length to less than 3/4 of the
wingspan or rotor length may further reduce drift without reducing swath width.
• Application Applications must 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.
Swath Adjustment
When applications are made with a cross-wind, the swath will be displaced downwind. 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 drops, etc.).
10
Wind
Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, including droplet
size and equipment type determine drift potential at any given speed. Application must 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 drift.
Temperature 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.
Temperature Inversion
Applications must 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 temperature 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 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 connected cloud (under low wind
conditions) indicates an inversion, while smoke that move upwards and rapidly dissipates indicates good
vertical air mixing.
Sensitive Areas
The pesticide must 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, non-target crops) is minimal
(e.g., when wind is blowing away from the sensitive areas).
FOR AERIAL APPLICATION IN CALIFORNIA ONLY
Do not apply this product using aerial application equipment in residential areas.
When tank mixing this product with 2,4-D for aerial applications, only 2,4-D amine formulations may be
used. This tank mixtur e may be used for fallow and reduced tillage systems and alfalfa and pasture
renovation applications only.
This product plus dicamba tank mixtures may not be applied by air in California.
AVOID DRIFT DO NOT APPLY WHEN WINDS ARE GUSTY OR UNDER ANY OTHER CONDITION
WHICH FAVORS DRIFT. DRIFT MAY CAUSE DAMAGE TO ANY VEGETATION CONTACTED TO
WHICH TREATMENT IS NOT INTENDED. TO PREVENT INJURY TO ADJACENT DESIRABLE
VEGETATION, APPROPRIATE BUFFER ZONES MUST BE MAINTAINED.
Use the following guidelines when aerial applications are made near crops or desirable perennial
vegetation after bud break and before total leaf drop, and/or near other desirable vegetation or annual
crops.

Aerial Applicator Training and Equipment
Aerial application of this product is limited to pilots who have successfully completed a Fresno County
Agricultural Commissioner and California Department of Pesticide Regulation approved training program
for aerial application of herbicides. All aircraft must be inspected, critiqued in flight and certified at a
Fresno County Agricultural Commissioner approved fly-in. Test and calibrate spray equipment at intervals
sufficient to ensure that proper rates of herbicides and adjuvants are being applied during commercial
use. Applicator must document such calibrations and testing. Demonstration of performance at Fresno
County Agricultural Commissioner approved fly-ins constitutes such documentation, or other written
records showing calculations and measurements of flight and spray parameters acceptable to the Fresno
County Agricultural Commissioner.
Applications at Night Do not apply this product by air earlier than 30 minutes prior to sunrise and/or
later than 30 minutes after sunset without prior permission from the Fresno County Agricultural
Commissioner.
Note: For aerial application from April 1 through February 14, refer to the “FOR AERIAL APPLICATION
IN CALIFORNIA ONLY” section of this label.
ARKANSAS ONLY
AVOID DRIFT. DO NOT APPLY INTO STILL AIR WHERE THERE IS A TEMPERATURE INVERSION
LAYER LOW ENOUGH FOR FINE SPRAY PARTICLES TO BECOME SUSPENDED AND MOVE
OUTSIDE THE TARGET AREA WHEN THE INVERSION LAYER MOVES. DO NOT APPLY WHEN
WINDS ARE GUSTY OR UNDER ANY OTHER CONDITION THAT FAVORS DRIFT. DRIFT IS LIKELY
TO CAUSE DAMAGE TO ANY VEGETATION CONTACTED. TO PREVENT INJURY TO ADJACENT
DESIRABLE VEGETATION, APPROPRIATE BUFFER ZONES MUST BE MAINTAINED.
Use the specified rate of this product in 3 to 15 gallons of water per acre. Use sufficient carrier volume
and appropriate equipment set-up to form droplets large enough to avoid drift potential. Coarse droplets
in the 300 to 500 (VMD) micron range are required.
Applications should typically be made with the nozzle release point at 8 to 15 feet above the top of the
target plants unless a greater height is required for aircraft safety. The distance of the outermost nozzles
on the boom must not exceed 75% of the length of the wingspan or rotor. In many cases reducing this
12
distance to 65% of the length of the wingspan or rotor will improve drift control without affecting the swath
width.
Nozzles must always discharge backward parallel with the airstream and never discharge downwards
more than 45 degrees on fixed wing aircraft or forward of the prevailing airflow on rotary winged aircra ft.
Avoid the use of nozzles with wide-angle discharge.
Do not apply this product when wind speeds are in excess of 10 miles per hour. Do not apply when there
is a low-level inversion where fine spray particles could be suspended in still air and move outside the
target area when the inversion layer moves. These conditions may occur when wind speeds are less than
2 mph.
Use the following guidelines when applications are made near crops or other desirable vegetation:
1. Do not apply within 100 feet of any desirable vegetation or crops.
2. If wind up to 5 miles per hour is blowing toward desirable vegetation or crops, do not apply within 500
feet upwind of the desirable vegetation or crops.
3. Winds blowing from 5 to 10 miles per hour toward desirable vegetation or crops will likely require
buffer zones in excess of 500 feet.
ARKANSAS, LOUISIANA, MISSISSIPPI, MISSOURI, AND TENNESSEE ONLY
This product controls annual and perennial weeds listed on this label prior to planting or emergence of
corn, cotton, rice, sorghum and soybeans; prior to the harvest of cotton and soybeans; and following the
harvest of any crop in the fall via aerial applications in these locations.
Aerial applications of this product may be m ade in fallow systems and conv entional, reduced and zero
tillage systems. For applications via aerial equipment, us e the specified rates of this product in 3 to 10
gallons of water per acre. Do not exceed a rate of 4.5 pts. per acre.
The likelihood of injury occurring from the use of this product is greatest when winds are gusty or in
excess of 5 miles per hour or when other conditions, including lesser velocities, will allow spray drift to
occur.
GROUND BROADCAST EQUIPMENT
Use the specified rates of this product in 3 to 40 gallons of water per acre as a broadcast spray unless
otherwise specified. As density of weeds increases, spray volume should be increased within the
specified range to ensure complete coverage. Carefully select proper nozzles to avoid spraying a fine
mist. For best results with ground application equipment, use flat fan nozzles. Check for even distribution
of spray droplets.
HAND-HELD AND HIGH-VOLUME EQUIPMENT
Apply to foliage of vegetation to be controlled. For applications made on a spray-to-wet basis, spray
coverage should be uniform and complete. Do not spray to the point of runoff. Use coarse sprays only.
For specified rates and timing, refer to the “Annual Weeds Hand-Held or High-Volume Equipment”
section of this product label.
SELECTIVE EQUIPMENT
This product may be applied through recirculating spray systems, shielded applicators, hooded sprayers,
wiper applicators or sponge bars, after dilution and thorough mixing with water, to listed weeds growing in
any noncrop site specified on this label.
In cropping systems, hooded sprayers, shielded sprayers, and wipers may be used in row middles (in
between rows of crop plants) where any dripping or leaking will not contact crop foliage. Such equipment
must be capable of preventing all crop contact with herbicide solutions and operated without leakage of
spray mists or dripping onto crop. Wipers over-the-top of crops may be used only when specifically
specified in this products labeling.
13
AVOID CONTACT OF HERBICIDE WITH DESIRABLE VEGETATION.
Contact of the herbicide solution with desirable vegetation may result in damage or destruction.
Applicators used above desirable vegetation should be adjusted so that the lowest spray stream or wiper
contact point is at least 2 inches above the desirable vegetation. Droplets, mist, foam, or splatter of the
herbicide solution settling on desirable vegetation may result in discoloration, stunting or destruction.
Applications made above the crops should be made when the weeds are a minimum of 6 inches above
the desirable vegetation. Better results may be obtained when more of the weed is exposed to the
herbicide solution. Weeds not contacted by the herbicide solution will not be affected. This may occur in
dense clumps, severe infestations or when height of the weeds varies so that not all weeds are
contacted. In these instances, repeat treatments may be necessary.
Recirculating Spray System
A recirculating spray system directs the spray solution onto weeds growing above desirable vegetation,
while spray solution not intercepted by weeds is collected and returned to the spray tank for reuse.
Shielded and Hooded Applicators
When applied under the conditions described in the following paragraphs for shielded and hooded
applications, this product at specified rates will control those weeds listed in the “ANNUAL WEEDS RATE
TABLE” and “PERENNIAL WEEDS RATE TABLE” sections of this label. A hooded sprayer is a type of
shielded applicator where the spray pattern is fully enclosed including top, sides, front and back, thereby
shielding the crop from the spray solution. Keep shields on these sprayers adjusted to protect desirable
vegetation. When applying to crops grown on raised beds, ensure that the hood is designed to completely
enclose the spray solution. If necessary, extend the front and rear flaps of the hoods to reach the ground
in deep furrows. EXTREME CARE MUST BE EXERCISED TO AVOID CONTACT OF HERBICIDE WITH
DESIRABLE VEGETATION.
This equipment must be set up and operated in a manner that avoids bouncing or raising the hoods off
the ground in any way. If the hoods are raised, spray particles may escape and come into contact with the
crop causing damage or destruction of the crop. Avoid operation on rough or sloping ground where the
spray hoods might be raised off the ground.
Use hoods designed to minimize excessive dripping or run-off down the insides of the hoods. A single,
low pressure / low drift flat-fan nozzle with an 80 to 95 degree spray angle positioned at the top center of
the hood is recommended. Spray volume should be 20 to 30 gallons per acre.
These procedures will reduce the potential for crop injury:
• The spray hoods must be operated on the ground or skimming across the ground.
• Leave at least an 8 inch untreated strip over the drill row. For example, if the crop row width is 38
inches, the maximum width of the spray hood should be 30 inches.
• Maximum tractor speed: 5 mph to avoid bouncing of the spray hoods.
• Maximum wind speed: 10 mph.
• Use low-drift nozzles that provide uniform coverage within the treated area.
Crop injury may occur when the foliage of treated weeds comes into direct contact with leaves of the
crop. Do not apply this product when the leaves of the crop are growing in direct contact with weeds to be
treated. Droplets, mist, foam or splatter of the herbicide solution may contact the crop and cause
discoloration, stunting or destruction.
Wiper Applicators
Wiper applicators are devices that physically wipe appropriate amounts of this product directly onto the
weed.
14
Equipment must be designed, maintained and operated to prevent the herbicide solution from contacting
desirable vegetation. Operate this equipment at ground speeds no greater than 5 mph. Performance may
be improved by reducing speed in areas of heavy weed infestations to ensure adequate wiper saturation.
Better results may be obtained if 2 applications are made in opposite directions.
Avoid leakage or dripping onto desirable vegetation. Adjust height of applicator to ensure adequate
contact with weeds. Keep wiping surfaces clean. Be aware that, on sloping ground, the herbicide solution
may migrate, causing dripping on the lower end and drying of the wicks on the upper end of a wiper
applicator.
Do not use wiper equipment when weeds are wet.
Mix only the amount of solution to be used during a 1-day period, as reduced activity may result from use
of leftover solutions. Clean wiper parts immediately after using this product by thoroughly flushing with
water.
Do not add surfactant to the herbicide solution.
For rope or sponge wick applicators: Mix 3 qts. of this product in 2 gallons of water to prepare a 33%
solution. Apply this solution to weeds listed in this section.
For porous-plastic applicators: Solutions ranging from 25% to 100% of this product in water may be
used in porous-plastic wiper applicators.
When applied as specified, this product CONTROLS the following weeds:
Corn, volunteer* Sicklepod
Panicum, Texas Spanishneedles
Rye, common Starbur, bristly
Shattercane
When applied as specified, this product SUPPRESSES the following weeds:
Beggarweed, Florida Ragweed, common

INJECTION SYSTEMS
This product may be used in aerial or ground injection spra y systems. It may be used as a liquid
concentrate or diluted prior to injecting into the spray stream. Do not mix this product with the concentrate
of other products when using injection systems.
CDA EQUIPMENT
The rate of this product applied per acre by vehicle-mounted CDA equipment must not be less than the
amount specified in this label when applied by conventional broadcast equipment. For vehicle-mounted
CDA equipment, apply 3 to 15 gallons of water per acre.
15
For the control of annual weeds with hand-held CDA units, apply a 20% solution of this product at a flow
rate of 2 fluid ounces per minute and a walking speed of 1.5 mph (1.5 pts. per acre). For the control of
perennial weeds, apply a 20 to 40% solution of this product at a flow rate of 2 fluid ounces per minute and
a walking speed of 0.75 mph (3 to 6 pts. per acre).
Controlled droplet application equipment produces a spray pattern that is not easily visible. Extreme care
must be exercised to avoid spray or drift contacting the foliage or any other green tissue of desirable
vegetation, as damage or destruction may result.

Bananacide (banana only)
USE INSTRUCTIONS: This product may be used to destroy banana plants infected with the Banana
Bunchy Top Virus as well as non-infected banana plants to establish disease free buffers around
plantations. Remove all fruit from the plants within the treatment area prior to treatment. Inject 0.04 fluid
ounce (1 mL) of this products concentrate per 2 to 3 inches of pseudostem diameter. Make the injection
at least one foot above the ground, except for very small plants, which should be injected vertically into
the top. Any subsequent regrowth must also be destroyed. All plants and mats (or units) adjacent (within
a 4 foot radius) to a treated mat shall be mechanically destroyed.
33
For control of the banana bunchy top virus, it is critical that the grower follow a strict control program
involving monitoring for diseased plants, spraying to control the aphid vector, and destruction of all
infected mats (or units). An infected plant may not show symptoms of the banana bunchy top virus for up
to 125 days; therefore, it is critical that the entire mat (or unit) containing the diseased plant be destroyed
immediately.
RESTRICTIONS: Do not apply more than 0.5 fluid ounce (15 mL) of this products concentrate per mat
(or unit). Remove all fruit from plants and mats (or units) following injection. Do not allow livestock to
consume treated plant materials. Following transplant of new banana plants into treated areas, allow
plants to become established for 3 months before applying this product for weed control.

this label.
Dormant (alfalfa only)
USE INSTRUCTIONS: This product will control or suppress many weeds including quackgrass, downy
brome, and cheatgrass in dormant alfalfa. Apply 6 to 9 fl. oz. per acre of this product. Apply in spring to
alfalfa that is dormant. Apply after spring temperatures have warmed enough to encourage resumption of
weed growth, but prior to initiation of trifoliate leaf expansion of the alfalfa. Applications made after
expansion of the first trifoliate leaf of the alfalfa will cause growth reduction and reduced crop yield.
PRECAUTION: Application of this product can cause crop injury. Any such crop injury is the responsibility
of the applicator. Do not use this product where a slight yield reduction in the first cutting of alfalfa cannot
be tolerated. Slight discoloration of the alfalfa may occur, but the alfalfa will regreen and regrow under
moist soil conditions as effects of this product wear off.
RESTRICTIONS: Do not use ammonium sulfate when spraying dormant alfalfa with Cornerstone® Plus
5. Do not make more than one application per year. Allow 36 hours after application before grazing
livestock or harvesting.
Preplant, Pre-emergence, and At-planting
USE INSTRUCTIONS: This product may be applied before, during or after planting crops listed in this
section. Applications must be made prior to emergence of the crop.
34
RESTRICTIONS: Remove domestic livestock before application. The crop may be fed or grazed as soon
as it reaches sufficient maturity.
Preharvest
USE INSTRUCTIONS: This product may be used in declining stands or any stand where crop injury or
destruction is acceptable. This product will control annual and perennial weeds, including quackgrass,
when applied prior to harvest. Applications may be made at any time of the year. For control of
quackgrass apply in the spring, late summer or fall when quackgrass is actively growing. Treatments for
quackgrass must be followed by deep tillage for complete control.
PRECAUTIONS: This application may destroy an alfalfa stand and may severely injure or destroy other
labeled crops such as clover. Preharvest application is not recommended for alfalfa grown for seed, as a
reduction in germination or vigor may occur.
RESTRICTIONS: Make only one application to an existing crop stand per year. The treated crop and
weeds can be harvested and fed to livestock according to the intervals below.

USE INSTRUCTIONS: This product may be applied as a spot treatment or with wiper applicators. For
additional information on wiper applicators, see the “SELECTIVE EQUIPMENT” section of this label.
Applications may be made in the same area at 30-day intervals.
RESTRICTIONS: For spot treatment and wiper applications, apply in areas where the movement of
domestic livestock can be controlled. No more than 10% of the total field may be treated at one time.
Remove domestic livestock before application and wait 3 days after application before grazing livestock
or harvesting.
Renovation
USE INSTRUCTIONS: This product may be applied as a broadcast spray to renovate existing stands of
alfalfa, clover, and other labeled forage legumes. If the crop is to be grazed or harvested for feed, use up
to 3 pts. per acre in alfalfa and up to 2.25 pints per acre in other labeled legumes. For complete removal
of established stands of clover it may be necessary to use the higher treatment rates listed in the
“PERENNIAL WEEDS RATE TABLE” in this label.
RESTRICTIONS: When treatment rates of 3 pts. per acre for alfalfa or 2.25 pints per acre for other forage
legumes are used, remove domestic livestock before application and wait 3 days after application before
reintroduction. If treatment rates above these levels are necessary, do not graze or harvest treated foliage
for livestock feed. Crops listed for treatment in this label may be planted into the treated area at any time;
for other crops, wait 30 days between application and planting.
Conservation Reserve Program (CRP)
Types of applications: Renovation (rotating out of CRP), site preparation, postemergence weed control
in dormant CRP grasses, wiper applications over-the-top.
Renovation (Rotating out of CRP), Site Preparation
USE INSTRUCTIONS: This product may be used to prepare CRP land for crop production. Refer to
Federal, state or local use guides for CRP renovation recommendations. For any crop not listed for
treatment in this label, applications must be made at least 30 days prior to planting.
35
Postemergence Weed Control in Dormant CRP Grasses, Wiper Applications Over-the-Top
USE INSTRUCTIONS: This product may be used to suppress competitive growth and seed production of
undesirable vegetation in CRP acres. Such applications may be made with wiper application equipment
or as a broadcast or spot treatment to dormant CRP grasses. For selective applications with broadcast
spray equipment, apply 9 to 12 fl. oz. of this product per acre in early spring before desirable CRP
grasses, such as crested and tall wheatgrass, break dormancy and initiate green growth. Late fall
applications can be made after desirable grasses have reached dormancy.
PRECAUTION: Some stunting of CRP perennial grasses will occur if broadcast applications are made
when plants are not dormant.
RESTRICTIONS: No waiting period is required between application and grazing or harvesting for feed.
Do not apply more than 4.5 pts. per acre per year onto CRP grasses.
Grass Seed or Sod Production
Labeled crops: Any grass ( Graminea family) except corn, sorghum, sugarcane and those listed in this
label under “Cereal and Grain Crops”.
Types of applications: Preplant, pre-emergence, at-planting, renovation, site preparation, shielded
sprayers, wiper applications over-the-top, spot treatments, creating rows in annual ryegrass.
USE INSTRUCTIONS: This product controls most existing vegetation prior to renovating turf or forage
grass areas or establishing turf grass grown for sod. Do not disturb soil or underground plant parts before
treatment. Tillage or renovation techniques such as vertical mowing, coring or slicing should be delayed
for 7 days after application to allow proper translocation into underground plant parts. Make applications
before, during, or after planting or for renovation.
For maximum control of existing vegetation, delay planting to determine if any regrowth from escaped
underground plant parts occurs. Where existing vegetation is growing under mowed turfgrass
management, apply this product after omitting at least one regular mowing to allow sufficient growth for
good interception of the spray. Where repeat treatments are necessary, sufficient regrowth must be
attained prior to application. For warm-season grasses, such as bermudagrass, summer or fall
applications provide best control. Broadcast equipment may be used to control sod remnants or other
unwanted vegetation after sod is harvested.
PRECAUTION: Applications must be made prior to the emergence of the crop to avoid crop injury.
RESTRICTIONS: If application rates total 4.5 pts. per acre or less, no waiting period between treatment
and feeding or livestock grazing is required. If the rate is greater than 4.5 pts. per acre, remove domestic
livestock before application and wait 8 weeks after application before grazing or harvesting. For any crop
not listed for treatment in this label, applications must be made at least 30 days prior to planting.
Shielded Sprayers
USE INSTRUCTIONS: Apply 1.5 to 4.5 pts. of this product in 10 to 20 gallons of water per acre to control
weeds between grass seed rows. Uniform planting in straight rows aid in shielded sprayer applications.
Best results are obtained when the grass seed crop is small enough to easily pass by the protective
shields.
For additional instructions, see “Shielded and Hooded Applicators” in the “APPLICATION EQUIPMENT
AND TECHNIQUES” section of this label.
PRECAUTION: Contact of this product in any manner to any vegetation to which treatment is not
intended may cause damage. Such damage shall be the sole responsibility of the applicator.
36
Wiper Applications Over-the-Top
USE INSTRUCTIONS: Applicators should be adjusted so that the wiper contact point is at least 2 inches
above the desirable vegetation. Weeds should be a minimum of 6 inches above the desirable vegetation.
Better results may be obtained when more of the weed is exposed to the herbicide solution. Weeds not
contacted by the herbicide solution will not be affected. This may occur in dense clumps, severe
infestations, or when height of weeds varies so that not all weeds are contacted. In these instances,
repeat treatments may be necessary. For additional instructions, see ”Wiper Applicators” in the
“APPLICATION EQUIPMENT AND TECHNIQUES” section of this label.
PRECAUTION: Contact of the herbicide solution with desirable vegetation may result in damage or
destruction.
Spot Treatments
USE INSTRUCTIONS: Use a 1.0 to 2.0% solution. Apply this product prior to heading of grasses grown
for seed. Hand-held equipment may be used to control sod remnants or other unwanted vegetation after
sod is harvested.
PRECAUTION: The crop receiving the spray in the treated area will be killed. Take care to avoid drift or
spray outside the target area for the same reason.
Creating Rows in Annual Ryegrass
USE INSTRUCTIONS: Use 0.75 to 1.5 pints of this product per acre. Use the higher rate when the
ryegrass is greater than 6 inches tall. Best results are obtained when applications are made before the
ryegrass reaches 6 inches in height.
PRECAUTIONS: Set nozzle heights to allow the establishment of the desired row spacing while
preventing spray droplets, spray fines, or drift to contact the ryegrass plants not treated. Use of low-
pressure nozzles, or drop nozzles designed to target the application over a narrow band are
recommended.
Grower assumes all responsibility for crop losses from misapplication.
Pasture Grasses
Labeled crops: Any grass (Gramineae family) except corn, sorghum, sugarcane and those listed in this
label under “Cereal and Grain Crops”. Grasses that may be treated include bahiagrass, bermudagrass,
bluegrass, brome, fescue, guineagrass, kikuyu grass, orchardgrass, pangola grass, ryegrass, timothy,
wheatgrass.
Types of applications: Preplant, pre-emergence, spot treatment, wiper applications over-the-top,
pasture renovation, postemergent weed control (broadcast treatments).
Preplant, Pre-emergence and Pasture Renovation
USE INSTRUCTIONS: This product may be applied prior to planting or emergence of forage grasses. In
addition, this product may be used to control perennial pasture species listed on this label prior to re-
planting.
RESTRICTIONS: If application rates total 4.5 pts. per acre or less, no waiting period between treatment
and feeding or livestock grazing is required. If the rate is greater than 4.5 pts. per acre, remove domestic
livestock before application and wait 8 weeks after application before grazing or harvesting. Crops listed
for treatment in this label may be planted into the treated area at any time; for other crops, wait 30 days
between application and planting.
Spot Treatment and Wiper Applications Over-the-Top
USE INSTRUCTIONS: This product may be applied as a spot treatment or with wiper applicators in
37
pastures. To achieve maximum performance, remove domestic livestock before application and wait 7
days after application before grazing livestock or harvesting. Applications may be made in the same area
at 30-day intervals.
RESTRICTIONS: For spot treatments or wiper application methods using rates of 4.5 pts. per acre or
less, the entire field or any portion of it may be treated. When spot treatments or wiper application are
made using rates above 4.5 pts. per acre, no more than 10% of the total pasture may be treated at any
one time.
Postemergent Weed Control (Broadcast Treatments)
USE INSTRUCTIONS: This product may be used to suppress competitive growth and seed production of
annual weeds and undesirable vegetation in pastures. For selective applications with broadcast spray
equipment, apply 9 to 12 fl. oz. of this product per acre in early spring before desirable perennial grasses
break dormancy and initiate green growth. Late fall applications can be made after desirable perennial
grasses have reached dormancy.
PRECAUTIONS: Some stunting of perennial grasses will occur if broadcast applications are made when
plants are not dormant. Use of higher application rates will cause stand reductions.
RESTRICTIONS: Do not apply more than 4.5 pts. per acre per year onto pasture grasses except for
renovation uses (see instructions above). If replanting is needed due to severe stand reduction,
applications must be made at least 30 days prior to planting any crop not listed for treatment in this label.
No waiting period is required between application and grazing or harvesting for feed.
Rangelands
Types of applications: Postemergence.
This product will control or suppress many annual weeds growing in perennial cool and warm-season
grass rangelands. Preventing viable seed production is key to the successful control and invasion of
annual grassy weeds in r angelands. Follow-up applications in sequential years should eliminate most of
the viable seeds. Grazing of treated areas should be delayed to encourage growth of desirable
perennials. Allowing desirable perennials to flower and reseed in the treated area will encourage
successful transition.
USE INSTRUCTIONS: Apply 9 to 12 fl. oz. of this product per acre to control or suppress many weeds,
including downy brome, cheatgrass, cereal rye and jointed goatgrass in rangelands. Apply when most
brome plants are in early flower and before the plants, including seedheads, turn color. Allowing for
secondary weed flushes to occur in the spring following rain events further depletes the seed reserve and
encourages perennial grass conversion on weedy sites. Fall applications are possible, and
recommended, where spring moisture is usually limited and fall germination allows for good weed growth.
For medusahead, apply 12 fl. oz. of this product per acre at the 3-leaf stage. Delaying applications
beyond this stage will result in reduced or unacceptable control. Controlled burning may be useful in
eliminating the thatch layer produced by slow decaying culms prior to application. Allow new growth to
occur before spraying after a burn. Repeat applications in subsequent years may be necessary to
eliminate the seedbank before reestablishing desirable perennial grasses in medusahead-dominated
rangelands.
Slight discoloration of the desirable grasses may occur, but they will regreen and regrow under moist soil
conditions as effects of this product wear off.
RESTRICTIONS: Do not use ammonium sulfate when spraying rangeland grasses with this product. No
waiting period between treatment and feeding or grazing of livestock is required. Do not apply more than
4.5 pts. per acre per year.

In-crop (Roundup Ready Glyphosate Tolerant Corn hybrids only): For in-crop Roundup Ready
glyphosate tolerant corn, apply a tank mixture of this product (24 fl. oz. per acre) plus Clarity (8 to 16 fl.
oz. per acre) or 2,4-D (0.5 to 1.0 pounds a.i. per acre). Apply between corn emergence and the 5-leaf
stage of growth (approximately 8 inches tall).
COTTON
Preplant: For control of horseweed, apply this product (24 fl. oz. per acre) in a tank mix with Clarity (8 fl.
oz. per acre). This application must be made 21 to 35 days before planting and before horseweed
reaches 6 inches in height. In order to avoid crop injury, a minimum interval of 21 days during which there
is at least 1 inch of cumulative rainfall must be observed between Clarity application and planting of
cotton.
Post-directed (Roundup Ready Glyphosate Tolerant Cotton varieties only): Management of early
season weed competition and the development of a crop height differential between cotton and the
horseweed is often achieved by a combination of preplant burndown and postemergent over-the-top
and/or directed applications of Cornerstone® Plus 5 herbicide. These measures enhance the
development of a height differential that is necessary to successfully make post-directed treatments. In-
crop post-directed applications of MSMA (2 pounds a.i. per acre) tank mixed with diuron (0.5 to 0.75
pounds a.i. per acre) should be made when the temperature is 80°F or higher.
SOYBEANS
Preplant: Apply a tank mixture of this product (24 fl. oz. per acre) with 2,4-D (0.5 pounds a.i. per acre)
before horseweed exceeds 6 inches in height. See the 2,4-D product label for time intervals that are

WOODY BRUSH AND TREES RATE TABLE
Apply this product after full leaf expansion, unless otherwise directed. Use higher rate for larger plants
and/or dense areas of growth. On vines, use the higher rate for plants that have reached the woody stage
of growth. Best results are obtained when application is made in late summer or fall after fruit formation.
In arid areas, best results are obtained when applications are made in the spring to early summer when
brush species are at high moisture content and are flowering.
Ensure thorough coverage when using hand-held equipment. Symptoms may not appear prior to frost or
senescence with fall treatments.
Allow 7 or more days after application before tillage, mowing or removal. Repeat treatments may be
necessary to control plants regenerating from underground parts or seed. Some autumn colors on
undesirable deciduous species are acceptable provided no major leaf drop has occurred. Reduced
performance may result if fall treatments are made following a frost.
