PRODUCT INFORMATION
Axial Star Herbicide is a postemergence systemic herbicide for the control of annual grasses
and broadleaf weeds in all varieties of spring wheat (excluding durum), winter wheat, and
barley not underseeded with legumes.
Axial Star Herbicide is absorbed by foliage and is rapidly translocated to the growing points of
leaves and stems of target weeds with growth stopping within days of application.
Susceptible grass weeds turn chlorotic (yellowing) within one to three weeks and are
completely controlled within three to five weeks. Susceptible broadleaf weeds exhibit twisting
and curling of stems (epinasty) and leaf cupping followed by growth inhibition and eventual
plant death within weeks. Level and rate of control depend on weed species, growing
conditions, crop competition, and coverage. Thorough spray coverage of target weeds is
essential for consistent control.
Rainfastness
Axial Star Herbicide is not affected by rain falling 1 hour or more after application.

Resistance Management
PINOXADEN GROUP 1 HERBICIDE
FLUROXYPYR GROUP 4 HERBICIDE
For resistance management, Axial Herbicide is a Group 1 herbicide (ACCase-inhibitor mode
of action) and a Group 4 herbicide (auxin mimic). Some naturally occurring grass weed
populations have been identified as resistant to herbicides with the ACCase-inhibitor mode of
action. Any weed population may contain or develop plants naturally resistant to Axial
Herbicide and other Group 1 and/or Group 4 herbicides. Selection of resistant biotypes,
through repeated use of these herbicides in the same field or lower than labeled use rates,
may result in weed control failures. The resistant biotypes may dominate the weed population
if these herbicides are used repeatedly in the same field. Appropriate resistance
management strategies should be followed. If resistance is suspected, contact your local
Syngenta representative and/or agricultural advisor for assistance.
Principles of Herbicide Resistant Weed Management
Scout and know your field
• Know weed species present in the field to be treated through scouting and field
history. An understanding of weed biology is useful in designing a resistance
management strategy. Ensure the weed management program will control all weeds
present.
• Fields should be scouted prior to application to determine species present and growth
stage. Always apply this herbicide at the full labeled rate and correct timing for the
weeds present in the field.
Utilize non-herbicidal practices to add diversity
• Use diversified management tactics including cover crops, mechanical weed control,
harvest weed seed control, and crop rotation as appropriate.
Use good agronomic practices, start clean and stay clean
• Use good agronomic practices that enhance crop competitiveness.
• Plant into weed-free fields utilizing tillage or an effective burndown herbicide for control
of emerged weeds.
• Sanitize farm equipment to avoid spreading seed or vegetative propagules prior to
leaving fields.
Difficult to control weeds
• Fields with difficult to control weeds should be planted in rotation with crops that allow
the use of herbicides with an alternative mode of action or different management
practices.
• Difficult to control weeds may require sequential applications, for example a broad
spectrum preemergence herbicide followed by one or more postemergence herbicide
-8-
applications. Utilize herbicides containing different modes of action effective on the
target weeds in sequential applications.
DO NOT overuse the technology
• DO NOT use more than two applications of this or any other herbicide with the same
mode of action in a single growing season unless mixed with an herbicide with a
different mode of action which provides overlapping spectrum for the difficult to control
weeds.
Scout and inspect fields following application
• Prevent an influx of weeds into the field by controlling weeds in field borders.
• Scout fields after application to verify that the treatment was effective.
• Suspected- herbicide resistant weeds may be identified by these indicators
• Failure to control a weed species normally controlled by the herbicide at the
dose applied, especially if control is achieved on adjacent weeds;
• A spreading patch of non-controlled plants of a particular weed species; and
• Surviving plants mixed with controlled individuals of the same species.
• Report non-performance of this product to your Syngenta retailer, Syngenta
representative, or call 1-866-Syngent(a) (866-796-4368). If resistance is suspected
ensure weed escapes are controlled using an herbicide with an effective mode of
action and/or use non-chemical means to prevent further seed production.
Prevent weed escapes before, during, and after harvest
• DO NOT allow weed escapes to produce seed or vegetative structures for example
tubers or stolons which contribute to spread and survival. Consider harvest weed
seed management and control weeds post-harvest to prevent seed production.
Resistant weeds
Contact your local Syngenta representative, retailer, crop advisor or extension agent to
determine if weeds resistant to the mode of action contained in this product are present in
your area. Premixes are intended to broaden the spectrum of weeds that are
controlled. Some weeds may be controlled by only one of the active ingredients in this
product. If resistant biotypes have been reported, use the full labeled rate of this product,
apply at the labeled timing, and tank-mix with an additional different mode of action product
so there are multiple effective modes of application for each suspected resistant weed.

CROP USE DIRECTIONS
Wheat and Barley
Axial Star Herbicide can be used on all varieties of spring wheat (excluding durum), winter
wheat, and barley.
Timing of Application
Apply Axial Star Herbicide to all varieties of spring wheat (excluding durum), winter wheat, and
barley from the 2-leaf stage to pre-boot stage.
For optimum results, apply Axial Star Herbicide to actively growing weeds. An early application
will maximize crop yields by reducing weed competition. Weed control following application of
Axial Star Herbicide alone or in combination with other herbicides can be reduced or delayed
under conditions of stress, such as drought, heat, insufficient fertility, flooding, and prolonged
cool temperatures. Optimum weed control will be obtained if application of Axial Star Herbicide
is delayed until the conditions of stress have ended and weeds are once again actively
growing. Weeds emerging after Axial Star Herbicide application will not be controlled.
USE RATE
Apply Axial Star Herbicide at 16.4 fl. oz./A in a minimum of 8 gallons up to 10 gallons of water
per acre.
USE RESTRICTIONS
• DO NOT apply to a crop that is stressed by conditions such as frost, low fertility,
drought, flooding, disease damage, or insect damage as crop injury may result.
• DO NOT allow spray to drift to adjacent fields seeded to crops other than wheat or
barley.
• DO NOT treat wheat or barley underseeded with legumes.
• Make only one application per 12 consecutive months.
• DO NOT graze livestock or harvest forage for hay from treated wheat and barley for a
minimum of 30 days following application.
• DO NOT harvest grain for 60 days following application.
• DO NOT feed treated wheat or barley straw to livestock for a minimum of 60 days
following application.
• This product is persistent and may be presen t in plant materials for over 30 days after
application. DO NOT use treated plant material for compost, mulch, or mushroom
spawn until 30 days after application.
-10-
• Animals that have been fed fluroxypyr-treated forage must be fed forage free of
fluroxypyr for at least 3 days before they are moved off the treated property.

An effective way to reduce spray drift is to apply large droplets. Use the largest droplets
that provide target pest control. While applying larger droplets will reduce spray drift, the
potential for drift will be greater if applications are made improperly or under unfavorable
environmental conditions.
Controlling Droplet Size – Ground Boom
• Volume - Increasing the spray volume so that larger droplets are produced will
reduce spray drift. Use the highest practical spray volume for the application. If a
greater spray volume is needed, consider using a nozzle with a higher flow rate.
• Pressure - Use the lowest spray pressure recommended for the nozzle to
produce the target spray volume and droplet size.
• Spray Nozzle - Use a spray nozzle that is designed for the intended application.
Consider using nozzles designed to reduce drift.

Controlling Droplet Size – Aircraft
• Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up
nozzles. Generally, to reduce fine droplets, nozzles should be oriented parallel
with the airflow in flight.
BOOM HEIGHT – Ground Boom
For ground equipment, the boom should remain level with the crop and have minimal
bounce.
RELEASE HEIGHT - Aircraft
Higher release heights increase the potential for spray drift.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded
sprayers. Verify that the shields are not interfering with the uniform deposition of the
spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce
effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. Temperature inversions are
characterized by increasing temperature with altitude and are common on nights with
limited cloud cover and light to no wind. The presence of an inversion can be indicated
by ground fog or by the movement of smoke from a ground source or an aircraft smoke
generator. Smoke that layers and moves laterally in a concentrated cloud (under low
wind conditions) indicates an inversion, while smoke that moves upward and rapidly
dissipates indicates good vertical air mixing. Avoid applications during temperature
inversions.
WIND
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING
GUSTY WIND CONDITIONS.
Applicators need to be familiar with local wind patterns and terrain that could affect
spray drift.
Boomless Ground Applications
Setting nozzles at the lowest effective height will help to reduce the potential for spray
drift

Handheld Technology Applications
Take precautions to minimize spray drift.
Sensitive Areas
This pesticide may only be applied when the potential for drift to adjacent sensitive
areas, e.g., residential areas, bodies of water, non-target plants is minimal, (i.e., when
the wind is blowing away from the sensitive area.)
Avoid all direct or indirect contact (such as spray drift) of Axial Star Herbicide with crops
other than those specified for treatment on this label since injury may occur.
Chemigation
Do not apply this product through any type of irrigation system.
MIXING PROCEDURES
Prior to using Axial Star Herbicide, ensure that the spray tank, lines, screens and filters
are thoroughly clean.
Mixing Instructions
1. Half fill spray tank with clean water. Start agitation or bypass system.
2. If a broadleaf herbicide mix partner is to be used, add the product FIRST prior to
adding Axial Star Herbicide and agitate for 2-3 minutes.
3. Add correct amount of Axial Star Herbicide.
4. Agitate for 2-3 minutes before adding remainder of water and then maintain
constant agitation.
5. After any break in spraying operations, a gitate thoroughly before spraying again.
6. Use the spray solution as soon as it is prepared.
Tank-Mix Compatibility Test
A jar test is recommended prior to tank mixing to ensure compatibility of Axial Star
Herbicide with mixture partners. Add proportion amounts of tank mixture components in
a clear quart jar one at a time in the recommended mixing order. Gently shake or invert
capped jar and let stand for 15-30 minutes. If the mixture clumps, forms flakes, oily films
or layers or other precipitates, it is not compatible and the tank mixture should not be
used.

CLEANOUT PROCEDURES FOR SPRAY EQUIPMENT
Thoroughly clean application equipment immediately after spraying Axial Star Herbicide.
Ensure that all traces of the product are removed. The following directions are
provided:
1. Drain any remaining spray mixture from the application equipment.
2. Hose down the interior surfaces of the tank. Flush tank, hoses, boom and
nozzles with clean water for 10 minutes. Fill the tank with water and recirculate
for 15 minutes. Spray the mixture through hoses, booms and nozzles and drain
tank. Ensure that the area at the end of the spray boom beyond the last nozzle
is flushed with water.
3. Remove all spray nozzles and screens and clean separately.
4. If spray equipment will be used for pesticide application to crops sensitive to Axial
Star Herbicide, steps 1-2 should be repeated.
5. Exterior surfaces of spray equipment should also be thoroughly cleaned.
Note: Rinsate may be disposed of onsite according to label use directions or at an
approved waste disposal facility.
STORAGE AND DISPOSAL
Do not contaminate water, food, or feed by storage or disposal.
Pesticide Storage
Store in a cool, dry, secure place. Do not store near seeds, fertilizers, or foodstuffs.
Pesticide Disposal
Pesticide wastes are toxic. Improper disposal of excess pesticides, spray mixture, or
rinsate is a violation of Federal law. If these wastes cannot be disposed of by use
according to label instructions, contact your State Pesticide or Environmental Control
Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for
guidance.
