Mode of Action
Trifludimoxazin, the active ingredient in TIREXOR, is a potent inhibitor of protoporphyrinogen-oxidase
(PPO) belonging to herbicide mode of action Group 14 (WSSA). TIREXOR is rapidly absorbed by roots
and foliage. Following inhibition of protoporphyrinogen-oxidase, plant death is the result of membrane
damage. Under active growing conditions, susceptible emerged weeds usually develop chlorotic and
necrotic injury symptoms within hours and die within a few days. Susceptible emerging weed seedlings
will usually die as they reach the soil surface or shortly after emergence.
Herbicide Resistance Management
Any weed population may contain or develop plants naturally resistant to TIREXOR and other Group 14
herbicides. Weed species with resistance to Group 14 may dominate the weed population if Group 14
herbicides are used repeatedly in the same field or in successive years as the primary method of control
for targeted species. This may result in partial or total loss of control of those species by TIREXOR or
other Group 14 herbicides.
To delay herbicide resistance consider:
 Resistance management should be part of a divers ified weed control strategy that integrates
chemical, cultural, and mechanical (tillage) control tactics. Cultural control tactics include crop rotation,
proper fertilizer placement, and optimum seeding rate/row spacing. Start with clean fields using tillage or
an effective burndown herbicide program. These practices encourage crop growth and improve
competitiveness against weeds.
 Clean equipment before moving to a different fi eld to avoid spread of resistant weeds.
 Scout fields prior to application to identify the weed spe cies present and their growth stage to
determine if the intended application will be effective.
 Always follow labeled application rate and weed growth stage specifications.
 Use sequential programs with preemergence herbic ides that provide soil residual control of weeds
to reduce early season weed competition and allow for timely in-crop postemergence herbicide
applications.
 DO NOT rely on a single herbicide site of action for weed control during the growing season.
 Avoid application of herbicides with the same site of action more than twice a season.
 Use tank mixes or premixes with other herbicides possessing different sites of action that are also
effective on the target weeds.
 Scout fields after herbicide application to identif y areas where weed control was ineffective.
 Control weed escapes with herbicides possessing a different site of action or use a mechanical
control measure. Weed escapes should not be allowed to reproduce by seed or to proliferate vegetatively.
 Contact your TIREXOR supplier and/or your local BASF representative to report weed escapes.
 Consult your local BASF representat ive, local or state cooperative extension service, professional
consultants or crop advisors, or other qualified authority to determine appropriate actions if you suspect
resistant weeds.
 Suspected herbicide-resistance 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 on non-controlled plants of a particular weed species; and
- surviving plants mixed with controlled individuals of the same species.

Application Instructions
Application Rate
Refer to the Agricultural Crop Uses – Specific Information and Non-Agricultural Uses –
Specific Information sections for specific application use rate directions and the restrictions by
agricultural/non-agricultural use pattern.

Application Timing
TIREXOR may be applied after previous crop harvest, during a fallow period, preceding crop planting as
preplant surface or preplant incorporated treatments, or after crop planting as preemergence treatment in
field and row agricultural crops. TIREXOR may be applied postemergence-directed in tree crops. Refer to
the Crop-specific Information section for specific application instructions (timings, rates, restrictions and
precautions) by crop.

Post-harvest Application
Apply TIREXOR as a broadcast spray after previous crop harvest and before the ground freezes for
burndown control of existing weeds. Tillage operations may be conducted before or after applying
TIREXOR. If tillage is used following an application, tillage must be no more than 2-inches deep to
uniformly incorporate the herbicide into the upper soil surface.

Fallow Application
Apply TIREXOR as a broadcast spray during a fallow period for burndown control of existing weeds
and/or residual control of germinating weeds during the fallow period.

Preplant Surface Application
Apply TIREXOR as broadcast spray within 45 days of planting for (early) preplant burndown control of
existing weeds and/or residual control of germinating weeds up to and through crop planting.

Preplant Incorporated Applications
Apply TIREXOR as a broadcast spray to the soil surface up to 14 days before planting and incorporate
into the upper soil surface (1 to 2 inches) using a harrow, rolling cultivator, field cultivator, or other
implement capable of providing uniform shallow incorporation. Avoid deeper incorporation or reduced
weed control may result.

Preemergence Surface Application
Apply TIREXOR as a broadcast spray to the soil surface after planting and before crop emergence.
TIREXOR must be applied before crop emergence or injury will occur.

Split Applications
Preplant surface applications may be applied as the initial part of a split application program where the
sequential applications (preplant incorporated, preemergence) are made near, at, or after crop planting
time. However, the cumulative use rate total from the split application program must not exceed the
maximum labeled rate for the crop.

Application Methods and Equipment
TIREXOR may be applied by ground (banded, broadcast, or spot) or air. Thorough spray coverage is
required for optimum broadleaf and grass weed control and can be improved with proper adjuvant, nozzle
and spray volume selection.
Use and configure application equipment for spray volume, accurate and uniform distribution of spray
droplets over the treated area, and to avoid spray drift to nontarget areas. Adjust equipment to maintain
continuous agitation during spraying with mechanical or bypass agitation. Avoid overlaps that will increase
rates above use rates specified in this label.

10

TIREXOR may be applied using water or sprayable fluid nitrogen fertilizer solutions as the spray carrier.
Additionally, TIREXOR may be impregnated on and applied with dry bulk fertilizer.

Mandatory Spray Drift Management

Aerial Application Requirements - Helicopter
Water Volume. Use 15 or more gallons of water per acre.
Applicators must follow these requirements to reduce the potential of spray drift to nontarget areas from
aerial applications with helicopter:
1. DO NOT release spray at a height greater than 10 feet above the vegetative canopy, unless a greater
application height is necessary for pilot safety.
2. Applicators must select nozzles and pressure that deliver medium to ultra-coarse droplets in
accordance with American Society of Agricultural & Biological Engineers Standard 641 (ASABE §641).
3. DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
4. The boom length must not exceed 75% of rotor blade diameter for helicopters.
5. Nozzles must be oriented so the spray is directed toward back of the helicopter.
6. Applicators must use ½ swath displacement upwind at the downwind edge of the field.
7. DO NOT apply during periods of temperature inversions.

Aerial Application Requirements – Fixed-wing Aircraft
Water Volume. Use 5 or more gallons of water per acre.
Applicators must follow these requirements to reduce the potential of spray drift to nontarget areas from
aerial applications:
1. DO NOT release spray at a height greater than 10 feet above the vegetative canopy, unless a greater
application height is necessary for pilot safety.
2. Applicators must select nozzles and pressure that deliver medium to ultra-coarse droplets in
accordance with American Society of Agricultural & Biological Engineers Standard 641 (ASABE §641).
3. DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
4. The boom length must not exceed 65% of the wingspan for aircraft.
5. Nozzles must be oriented so the spray is directed toward back of the aircraft.
6. Applicators must use ½ swath displacement upwind at the downwind edge of the field.
7. DO NOT apply during periods of temperature inversions.

Ground Application Requirements
Spray Carrier Volume. Use 10 or more gallons of water per treated acre or 20 or more gallons of
sprayable fluid nitrogen fertilizer per treated acre.
Applicators must follow these requirements to reduce the potential of spray drift to nontarget areas from
ground applications:
1. Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the
ground or crop canopy.
2. Applicators must select nozzles and pressure t hat deliver medium to ultra-coarse droplets in
accordance with American Society of Agricultural & Biological Engineers Standard 572 (ASABE
§572).
3. DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
4. DO NOT apply during temperature inversions.

Spray Drift Advisories
The applicator is responsible for avoiding off-site spray drift. Be aware of nearby non-target sites and
environmental conditions.

Importance of Droplet Size
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
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage.
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. When applying aerially to crops, do not
release spray at a height greater than 10 ft above the crop canopy, unless a greater application height is
necessary for pilot safety.

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 Inversion
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.
Cleaning Spray Equipment
Clean application equipment thoroughly by using a strong detergent or commercial sprayer cleaner
according to the manufacturer’s directions, followed by triple rinsing the equipment before and after
applying this product.

12

Ground Application (dry bulk fertilizer)
TIREXOR may be impregnated or coated onto dry bulk granular fertilizer carriers for residual soil surface
application. Impregnation or coating may be conducted by in-plant bulk or on-board systems. Perform the
mixing operation in well-ventilated areas.

Addition of a drying agent may be necessary if the fertilizer and herbicide blend is too wet for uniform
application because of high humidity, high urea concentration, or low fertilizer use rate. Slowly add the
drying agent to the blend until a flowable mixture is obtained. Drying agents are not intended for use with
on-board impregnation systems.

Under some conditions, fertilizer impregnated with TIREXOR may clog air tubes or deflector plates on
pneumatic application systems. Mineral oil may be added to TIREXOR before blending with fertilizer to
reduce plugging. DO NOT use drying agents when mineral oil is used. To avoid separation of TIREXOR
and mineral oil mixes in cold temperatures, keep mixture heated or agitate before blending with fertilizer.
Mineral oil may be used with in-plant blending stations or on-board injection systems.

Generally, fertilizer application rates of at least 200 lbs to 700 lbs per acre of herbicide and fertilizer blend
provide adequate distribution or coverage of TIREXOR across the soil surface. Application must be made
uniformly to the soil to prevent possible crop injury and offer satisfactory weed control. Impregnated
fertilizer spread at half rate and overlapped for a full rate offers a more uniform distribution. A shallow (less
than 2 inches) incorporation is desirable for improved weed control. Deeper incorporation dilutes the
herbicide layer near the soil surface and may result in unsatisfactory weed control.

To calculate the herbicide rate when using dry bulk fertilizer application:
fl ozs herbicide per acre/pounds fertilizer per acre X 2000 = fl ozs herbicide per ton of fertilizer

Additives
For optimum burndown activity with TIREXOR, an adjuvant system must be used that includes the
following:
Adjuvant Rate
Methylated seed oil (MSO)1 1 gal/100 gals (1% v/v)2
PLUS PLUS
Ammonium sulfate (AMS)

Compatibility Test for Mix Components

Before mixing components, always perform a compatibility jar test.
1. For 20 gallons per acre spray volume, use 3.3 cups (800 mL) of water. For other spray volumes, adjust
rates accordingly. Only use water from the intended source at the source temperature.
2. Add components in the sequence indicated in Mixing Order using 2 teaspoons for each pound or 1
teaspoon for each pint of label rate per acre.
3. Always cap the jar and invert 10 cycles between component additions.
4. When the components have all been added to the jar, let the solution stand for 15 minutes.
5. Evaluate the solution for uniformity and stability. The spray solution shall not have free oil on the
surface, or fine particles that precipitate to the bottom, or thick (clabbered) texture. If the spray solution is
not compatible, repeat the compatibility test with the addition of a suitable compatibility agent. If the
solution is then compatible, use the compatibility agent as directed on its label. If the solution is still
incompatible, DO NOT mix the ingredients in the same tank.

Mixing Order

Maintain agitation throughout mixing and application until spraying is completed. Except when mixing
products in PVA bags, maintain constant agitation during mixing and application.
1. Water - Fill tank to 1/2 to 3/4 full with clean water and start agitation.
2. Inductor - If an inductor is used, rinse it thoroughly after each component has been added.
3. Products in PVA bags - Place any product contained in water-soluble PVA bags into the mixing tank.
Wait until all water-soluble PVA bags have fully dissolved and the product is evenly mixed in the spray
tank before continuing.
4. Water-soluble additives (including dry and liquid fertilizers AMS or UAN)
5. Water-dispersible products (dry flowables, wettable powders, suspension concentrates, or suspo-
emulsions)
6. Water-soluble products
7. Emulsifiable concentrates (including MSO adjuvants)
8. Remaining quantity of water

If the spray mixture is allowed to settle for any period of time, thorough agitation is essential to resuspend
the mixture before spraying is resumed. Continue agitation while spraying.

Application Rate, Method, and Timing
Apply TIREXOR up to 4.11 fl ozs/A in citrus fruit or up to 2.74 fl ozs/A in tree nuts and pome fruit plus the
required adjuvants (refer to Additives section for details) as a postemergence-directed spray either as a
uniform broadcast, banded, or spot application directed at the base of the tree trunks while targeting
emerged broadleaf weeds and grasses (refer to Table 2 and Table 3 for weeds controlled). Rates higher
than listed in Table 2 and 3 provide additional length of residual control. Spray contact of tree foliage,
flowers, buds, or fruit either directly via improper nozzle orientation or indirectly via physical drift will result
in crop injury. The use of shielded sprayers is highly advised when applying in citrus trees with low
hanging branches and fruit.
TIREXOR may be applied either in a single application or sequentially.
Applications can be made to newly planted or replacement citrus trees after irrigation or rainfall has
settled the soil, while nut trees and pome fruit trees must be established for at least 12 months prior to
application. Trunk shields must be used until adequate bark has formed to protect trees from potential
herbicide injury (typically by 2 to 3 years after establishment).
Spot Treatment
Consult the chart following for the amount of TIREXOR for making various gallons of spray mix to be used
for spot treatments applied to actively growing broadleaf and grass weeds and sizes referenced in
Table 3. Coverage is important. Spray thoroughly to wet the weed foliage but not to point of runoff. To
maximize performance, refer to the Additives section for the adjuvant and rate to be added to the spray

16

mix. Each spray mix is equivalent to applying TIREXOR at a use rate of 0.68 fl oz/A in a spray volume of
100 gallons per acre. Applications of a spot spray mix must not be made to an equivalent area less than
what is shown in the chart or exceed the equivalent broadcast rate of 0.68 fl oz/A. Spot treatments may be
applied with backpack sprayers or via an ATV-mounted (all-terrain vehicle-mounted) or tractor / truck
mounted sprayers equipped for hand wand applications. Spot applications can be made sequentially
and/or be combined with broadcast / banded applications, but the maximum cumulative amount applied
must not exceed the total use rate for the crop per year (see Crop-specific Restrictions).

b To provide effective residual control of labeled weed species, TIREXOR must be used at the maximum use rate of
4.11 fl ozs/A.

Use Restrictions for All Non-Agricultural Uses

 DO NOT apply more than 4.11 fl ozs/A (0.134 lb ai/A) of TIREXOR in a single application or as a
maximum cumulative amount from sequential applications per year.
 Sequential applications must be separated by at least 14 days.
 Maximum number of applications per year: 3


Weed Control for All Non-Agricultural Uses

In addition to weeds listed in Table 2 and 3, TIREXOR controls the following weed species in non-
agricultural use sites:

Common Name Scientific Name
Needles, Spanish Urtica urens
Parthenium Parthenium hysterophorus
Pine Pinus spp.

Wildling Pine Control
Apply TIREXOR for rapid brownout of wilding (volunteer) pine, including loblolly pine (Pinus taeda) and
Virginia pine (P. virginiana). For best control, apply TIREXOR as a uniform broadcast spray with a labeled
rate of a glyphosate-based product plus the required adjuvant (see Additives section for specifics) in

25

addition to other tank mix herbicides. Make foliar applications in the spring, summer, and early fall when
wildling pine seedlings are actively growing. Mid-to-late fall applications to wildling pines when growth is
slowing may not provide consistent control. Thorough spray coverage of broadcast foliar applications is
essential for control. Use a spray volume of 15 gallons of water per acre or more for aerial application.
Use a spray volume of 20 gallons of water per acre or more for ground application.

Tank Mixes for All Non-Agricultural Uses

It is the pesticide user’s responsibility to ensure that all products in the listed mixtures 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.

Broad-spectrum control of additional broadleaf and/or grass weeds requires a tank mix with another
herbicide. Read and follow the applicable restrictions and precautions and directions for use on the other
product label. The most restrictive labeling applies to tank mixes. TIREXOR may be tank mixed or applied
sequentially with other herbicide products, including but not limited to:

 glyphosate
 saflufenacil

Spot Treatment for All Non-Agricultural Uses

Postemergence spot application may be made with TIREXOR using backpack sprayers or via an ATV-
mounted (all-terrain vehicle-mounted) or tractor / truck mounted sprayers equipped for hand wand
applications. Spray volumes must be sufficient to thoroughly wet target area and/or foliage but not to the
point of runoff, i.e. a spray-to-wet basis. See the following chart for amount(s) of TIREXOR to prepare
spray solutions for spot application.
To maximize performance, refer to the Additives section for the required adjuvant and rate to add to the
spray mix.
Each spray mix is equivalent to applying TIREXOR at 4.11 fl ozs/A in a spray volume of 100 gallons per
acre. Applications of a spot spray mix should not be made to an equivalent area less than what is shown
in the chart or exceed the equivalent broadcast rate of 4.11 fl ozs/A.

Application Rate, Method, and Timing
Bareground
Apply TIREXOR for contact burndown plus residual preemergence control of broadleaf and grass weeds.
Apply TIREXOR with a labeled rate of a glyphosate-based product plus the required adjuvant (refer to
Additives section for details) as a uniform broadcast application. To provide effective residual broadleaf
weed and grass control, TIREXOR must be applied at the maximum use rate of 4.11 fl ozs/A. The actual
length of residual control depends on factors including soil type, organic matter, weed pressure, and
rainfall amounts after application. Precipitation is necessary to activate TIREXOR. Dry weather following
application may reduce effectiveness.
Selective Weeding
Apply TIREXOR as a postemergence spray with a labeled rate of a glyphosate-based product plus the
required adjuvant (refer to Additives section for details) as a uniform broadcast application for selective
weed control.

Selective Stem Application
Apply TIREXOR in a tank mix with glyphosate and/or other tank mix herbicides plus the required adjuvant
(refer to Additives section for specifics) for rapid brownout of woody species using a directed-foliar
individual plant treatment. For enhanced brownout of pine species (including loblolly pine [Pinus taeda]
and Virginia pine [P. virginiana]), tank mix with glyphosate or other pine control herbicides. Make selective
stem applications of TIREXOR using backpack or hydraulic handgun equipment. For best results, apply
TIREXOR at a rate of 4.11 fl ozs in a spray volume of 100 gallons per acre with a tank mix partner (refer
to tank mix partner label for the use rate). The proper spray pattern for selective stem applications is to
uniformly wet all foliage on the target plant without drenching target vegetation causing spray solution to
run off. For best results, make selective stem applications with methylated seed oil at 1% v/v as the
adjuvant. Apply TIREXOR up to 4.11 fl ozs/A with selective stem applications.

Use-specific Restrictions
 DO NOT apply more than 4.11 fl ozs/A (0.134 lb ai/A) of TIREXOR in a single application or as a
maximum cumulative amount from sequential applications per year.
 Sequential applications must be separated by at least 14 days.
 Maximum number of applications per year: 3

 DO NOT feed or allow domestic animals to graze areas of grass treated with TIREXOR within 365
days of application.
