PRODUCT INFORMATION
Vios™ FX Herbicide:
• is applied as a postemergence foliar spray in winter wheat and spring wheat for the control of certain annual grasses
and broadleaf weeds.
SPRAY DRIFT MANAGEMENT
MANDATORY SPRAY DRIFT
Aerial Applications:
• Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a
greater application height is necessary for pilot safety.
• Applicators are required to use a medium or coarser droplet size (ASABE S572) for all applications.
• If the windspeed is 10 miles per hour or less, applicators must use ½ swath displacement upwind at the
downwind edge of the field. When the windspeed is between 11-15 miles per hour, applicators must use
¾ swath displacement upwind at the downwind edge of the field.
• Do not apply when wind speeds exceed 15 mph at the application site. If the windspeed is greater than
10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 75% or less of
the rotor diameter for helicopters. Otherwise, the boom length must be 75% or less of the wingspan for
fixed- wing aircraft and 90% or less of the rotor diameter for helicopters.
• Do not apply during temperature inversions.
Ground Boom Applications:
• User must only apply with the release height recommended by the manufacturer, but no more than 4 feet
above the ground or crop canopy.
• Applicators are required to use a medium or coarser droplet size (ASABE S572). Do not apply when wind
speeds exceed 15 miles per hour at the application site.
• 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.
BOOM HEIGHT – Ground Boom
• For ground equipment, the boom should remain level with the crop and have minimal bounce.
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.
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.
Sensitive Areas
The pesticide should 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, nontarget crops) is minimal (e.g.,
when wind is blowing away from the sensitive areas).
USE RESTRICTIONS
• DO NOT apply Vios FX Herbicide to crops undersown with grass or legume species.
• DO NOT make more than one application of Vios FX Herbicide per 365 days.
• DO NOT apply more than 13.7 fl oz/A (0.004 pounds thiencarbazone - methyl and 0.105 pounds acid
equivalent of fluroxypyr ((4-amino-3,5-dichloro-6- fluoro-2-pyridinyl)oxy) acetic acid) of Vios FX Herbicide
per 365 days.
• DO NOT apply more than 0.04 pounds/A of Thiencarbazone-methyl from all sources per 365 days.
• DO NOT apply more than 0.25 pounds/A of fluroxypyr from all sources per 365 days
• DO NOT apply in combination with Dicamba containing products as grass control will be reduced.
• DO NOT apply Vios FX Herbicide in tank mixture with tebuconazole
• DO NOT apply Vios FX Herbicide through any type of irrigation system.
• DO NOT drain or rinse equipment near desirable vegetation.
• DO NOT apply to winter or spring wheat after jointing.
• DO NOT harvest or graze wheat forage within 7 days after application.
• DO NOT harvest winter wheat or spring wheat for hay within 30 days after application.
• DO NOT harvest wheat for grain or straw within 60 days after application in Minnesota, Montana, North
Dakota, or South Dakota; and within 70 days in all other states.
USE PRECAUTIONS
• Avoid spray drift from treated areas. Refer to the Spray Drift Management section of this label for
additional information.
• Vios FX Herbicide is rainfast 1 hour after application to most weed species. Rainfall within 1 hour may
result in reduced weed control.

4
• Non-target plants may be adversely affected if the pesticide is allowed to drift from areas of application.
To prevent damage to crops and other desirable plants, read and follow all directions and precautions on
this label before using.
• Environmental conditions which support vigorous growth of crop and weeds also result in highest
herbicidal activity. Following application, symptoms of herbicidal activity may develop within several
days. Speed of action depends on environmental conditions and increases with increasing temperature
and moisture.
• Applications of Vios FX Herbicide in winter wheat or spring wheat in combination with some EC herbicides
may cause crop response (see tank mix section).
• Applications during low temperatures (32ºF or lower), high temperatures (90ºF or greater), or to a crop
under drought stress can cause crop injury.
APPLICATION INSTRUCTIONS
• Weed infestations should be treated before they become competitive with the crop. Make applications to
actively growing weeds. Thorough coverage of weeds is necessary to obtain good weed control. Weed
control may be reduced when weeds are under stress due to severe weather conditions, drought, very
cold temperatures, etc. Temperature range for optimal herbicidal activity is 55ºF to 75ºF .
• Properly calibrate ground or aerial (fixed wing or helicopter) application equipment to apply Vios FX
Herbicide postemergence as a foliar spray. Use of nozzles and spray pressure that deliver medium to
coarse  spray droplets as indicated in the nozzle manufacturer’s catalogs and in accordance with ASABE
Standard S-572 for optimum spray coverage and canopy penetration.
• Avoid uneven spray distribution, skips, overlaps, and spray drift.
Aerial Application
Calibrate the spray equipment prior to use. Vios FX Herbicide should be applied in a minimum of 5 gallons of
water per broadcast acre.
Ground Application
Apply Vios FX Herbicide broadcast in 10 or more gallons of water per acre.
WEED RESISTANCE MANAGEMENT
For resistance management, Vios FX Herbicide is a Group 2 (thiencarbazone-methyl) and Group 4
(fluroxypyr-methylheptyl) herbicide. Any weed population may contain or develop plants naturally resistant
to Vios FX Herbicide and other Group 2 and Group 4 herbicides. 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.
To delay herbicide resistance take one or more of the following steps:
• Rotate the use of Vios FX Herbicide or other Group 2  and Group 4 herbicides within a growing season
sequence or among growing seasons with different herbicide groups that control the same weeds in a field.
• Use tank mixtures with herbicides from a different group if such use is permitted; where information
on resistance in target weed species is available, use the less resistance-prone partner at a rate that
will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local
extension service or certified crop advisor if you are unsure as to which active ingredient is currently less
prone to resistance.
• Adopt an integrated weed-management program for herbicide use that includes scouting and uses
historical information related to herbicide use and crop rotation, and that considers tillage ( or other
mechanical control methods), cultural ( e.g., higher crop seeding rates; precision fertilizer application
method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties)
and other management practices.
• Fields should be scouted prior to application to identify the weed species present and their growth stage
to determine if the intended application will be effective.
• Scout after herbicide application to monitor weed populations for early signs of resistance development.
Indicators of possible herbicide resistance include: (1) failure to control a weed species normally controlled
by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading
patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with controlled
individuals of the same species. If resistance is suspected, prevent weed seed production in the affected
area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment
when moving between fields, and planting clean seed.
• If a weed pest population continues to progress after treatment with this product, discontinue use of this product,
and switch to another management strategy or herbicide with a different mode of action, if available.
• Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management
and/or integrated weed-management recommendations for specific crops and weed biotypes.
• For further information or to report suspected resistance contact Bayer CropScience at 1-866-99BAYER
(1-866-992-2937). You can also contact your pesticide distributor or university extension specialist to
report resistance.

Order of Mixing
Vios FX Herbicide must be applied with clean and properly calibrated equipment. Prior to adding Vios FX
Herbicide to the spray tank, ensure that the spray tank, filters and nozzles have been thoroughly cleaned.
In-line strainers and nozzle screens should be 50 mesh or coarser.
1. Fill the spray tank 1/4 to 1/2 full with clean water and begin agitation or bypass.
2. Add a listed tank mix partner, if desired. Please check Tank Mix section for optimum mixing suggestions
3. Add the specified rate of Vios FX Herbicide directly to the spray tank. Maintain sufficient agitation during
both mixing and application. DO NOT pre-slurry by adding any quantity of Vios FX Herbicide to a small
amount of water.
4. Fill the spray tank with balance of water needed.
5. Continue agitation during Vios FX Herbicide application to ensure uniform spray coverage.
NOTE: Vios FX Herbicide may settle if left standing without agitation.  If the spray solution is allowed to stand
for one hour or more, re-agitate the spray solution for a minimum of 10 minutes before application.

6
Equipment Cleanup Procedures
1. Drain the tank completely, and then wash out tank, boom and hoses with clean water. Drain again.
2. Half fill the tank with clean water and add ammonia (i.e., 3% domestic ammonia solution) at a dilution rate
of 1% (i.e., 1 gallon of domestic ammonia for every 100 gallons of rinsate). Complete filling of the tank with
water. Agitate/recirculate and flush through boom and hoses. Leave agitation on for 10 minutes. Drain tank
completely.
3. Repeat step 2.
4. Remove nozzles and screens and soak them in a 1% ammonia solution. Inspect nozzles and screens and
remove visible residues.
5. Flush tank, boom, and hoses with clean water.
6. Inspect tank for visible residues. If present, repeat step 2.

Cover Crops
Use of cover crops as a means of soil improvement, erosion control, weed and/or insect suppression, etc.,
following harvest in the fall is increasing. Planting of cover crops in fields treated with Vios FX Herbicide is
allowed as long as these cover crops are not grazed by livestock nor harvested for food. Cover crops are to
be tilled under or chemically controlled with burndown herbicides in the spring.  Many cover crops can be
planted within 90-120 days after application of Vios FX Herbicide. However, all potential cover crops have not
been evaluated for tolerance to Vios FX Herbicide and significant injury may occur.  Prior to seeding a cover
crop, complete a successful field/ small scale bioassay to provide an indication of the level of tolerance to the
prior Vios FX Herbicide application. Refer to the “Field/Small Scale Bioassay” section.
Field/Small Scale Bioassay
A field/ small scale bioassay must be completed before rotating to a cover crop other than those specified in
the “Rotational Crop Restrictions” section of this label. To conduct an effective field bioassay, grow strips of
the crop(s) you intend to grow the following season in a field previously treated with Vios FX Herbicide. The
test strip should be placed in a controlled area and should include low areas and knolls, and include variations
in soil such as type and pH. Crop response to the bioassay will determine if the crop(s) grown in the test strips
can be grown safely in the areas previously treated with Vios FX Herbicide.
For an effective small scale bioassay, collect uniform samples of all soil types from the Vios FX Herbicide-treated
field and place the soil into a sturdy container.  Plant the desired cover crop into the soil, apply water and place
the container in a warm, sunny area to allow germination and growth of the crop.  Monitor growth of the cover
crop over a three to four week period.  If the cover crop emerges and grows normally, the risk to establish and
grow the cover crop in the Vios FX Herbicide-treated field should be tolerable.
WEEDS CONTROLLED & PARTIALLY CONTROLLED
Vios FX Herbicide effectively controls the following weeds when applied at the application timings
recommended and when weeds are actively growing. Best control is achieved when grass weeds are
treated between the 1-leaf to 1-tiller stage of growth and broadleaf weeds are between the 1-6 leaf stage of
growth, unless otherwise indicated. Vios FX Herbicide will have an effect on weeds that are larger than the
recommended leaf stage; however the speed of activity and level of control may be reduced.
