GENERAL INFORMATION 
OLYMPUSTM FLEX Herbicide is intended for postemergence application as a foliar spray in fall-sown or winter wheat or triticale for the 
control: of annual grass and broadleaf weeds. This product requires the addition of an adjuvant as specified in this label. 
ENVIRONMENTAL AND BIOLOGICAL ACTIVITY 
OLYMPUSTM FLEX Herbicide is absorbed by foliage and roots of weeds and offers contact and residual weed control. OLYMPUSTM 
FLEX Herbicide provides the most consistent control when applied to actively growing weeds. OLYMPUSTM FLEX Herbicide is active 
against many important grass and broadleaf weeds (see list below for details). Best weed control can be expected when applications 
are made after the crop has fully emerged (fully expanded first true leaf) and before grass weeds tiller. 
Environmental conditions which support vigorous growth of crop and weeds 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. Sensitive weeds quickly stop growing and no longer compete with the crop. Visible signs of 
activity include cessation of elongation, yellowing and/or reddening of weeds, and finally plant death. 
Abnormal environmental conditions (excess soil moisture or drought, extreme cold weather) can influence crop tolerance and herbicidal 
activity and may cause temporary response to the crop or reduced levels of weed control. This may result in weed stunting, rather than 
weed death. However, weed competition will be greatly reduced, and should permit normal crop development. Crop response may 
occur when frost occurs shortly after application to actively growing wheat. 
CROPS 
OLYMPUSTM FLEX Herbicide may be used on fall-sown or winter wheat and fall sown triticale. 
VARIETIES 
If OL YMPUSTM FLEX Herbicide is tankmixed with any other product, refer to the label of the tankmix partner for further instructions and 
potential restrictions (timing of application, varietal tolerance). 
SURFACTANTS 
OL YMPUSTM FLEX Herbicide is a water dispersible granule that does not include an adjuvant. A recommended adjuvant must be 
tankmixed with OLYMPUSTM FLEX Herbicide according to the guidelines as described in the MIXING INSTRUCTIONS section. 
OLYMPUSTM FLEX Herbicide offers the flexibility to choose between three distinct adjuvant systems including 1) non-ionic surfactant 
plus ammonium nitrogen fertilizer, 2} methylated seed oil or 3} "basic blend" type adjuvant. 
Do not use additives that alter the spray solution below 6.0 pH. Best results are obtained at spray solution pH of 6.0 - 8.0. 
organosilicone-based surfactants or crop oil concentrate surfactants are not recommended for use with OL YMPUSTM FLEX Herbicide. 
1) Non-ionic Surfactant (NIS) + Ammonium Nitrogen Fertilizer (in water carrier solutions) 
Use a non-ionic surfactant at a concentration of 0.5% vlv (2 qts per 100 gallons of spray solution) with ammonium nitrogen fertilizer. At 
least 80% of the surfactant product must be active non-ionic surfactant. Avoid products that do not accurately define their ingredients. 
Products must contain only EPA-exempt ingredients (40 CFR 1001). 
Use a spray grade quality urea ammonium nitrogen fertilizer (28-0-0 or 30-0-0 or 32-0-0 at 1 - 2 qtlacre) or ammonium sulfate fertilizer 
(21-0-0-24 at 1.5 - 3Ibs/acre). 
2) Methylated Seed Oil (MSO) 
A high quality methylated seed oil containing at least 80% methylated seed oil and 10% emulsifier or greater may be used in 
tankmixture with OL YMPUSTM FLEX Herbicide at a rate of 1.3 - 1.5 ptlacre, however, potential for crop response may be increased 
compared to non-ionic surfactant plus ammonium nitrogen fertilizer. 
When a methylated seed oil is used, ammonium nitrogen or ammonium sulfate fertilizers are not recommended. 
3) Basic Blend Adjuvants 
A basic blend adjuvant is a formulated combination of a non-ionic surfactant or methylated seed oil and a nitrogen source. Apply a 
basic blend adjuvant at 1 % v/v or 0.8 - 1.6 ptlacre depending on water carrier volume per acre with OL YMPUSTM FLEX Herbicide. 
Select the appropriate amount of basic blend adjuvant per acre depending on local conditions. 
When a basic blend adjuvant is used, ammonium nitrogen or ammonium sulfate fertilizers are not recommended. 
APPLICATION IN FLUID FERTILIZER CARRIER 
OL YMPUSTM FLEX Herbicide provides consistent performance when applied with water as the spray carrier and the appropriate 
additive is added to the spray solution. However, OLYMPUSTM FLEX Herbicide may be applied using a liquid nitrogen solution (28-0-0, 
30-0-0 or 32-0-0) as a portion of the spray carrier. A non-ionic surfactant at a maximum concentration of 0.25% vlv (1 quart per 100 
gallons of spray solution) is required in spray solutions containing liquid nitrogen carrier. 
Kansas, Oklahoma, and Texas - OLYMPUSTM FLEX Herbicide may be applied in a fertilizer spray _ soltJt!,on corit"!;.nin£', up to a 
maximum of 50% v/v liquid nitrogen (5 gallons of liquid nitrogen in 10 gallons of spray solution per acre) and ntt exceed "'.are than 30 
pounds of actual nitrogen per acre. . . 
Washington, Oregon and Idaho - OLYMPUSTM FLEX Herbicide may be applied in a fertilizer spraysolidon co;)taining up to 3 
gallons of liquid nitrogen in a minimum 10 gallon spray solution per acre by ground only. Liquid nitrogen mayi~clude fCmlu:z.ti(:>ns from 
20-0-0 to 32-0-0. 
In all other areas, the fertilizer spray solution may be applied up to a maximum of 15% vlv liquid nitrogen.(1 is g&lIons of liquid nitrogen 
in 10 gallons of spray solution per acre). . .1 
l1.,

s--Due to the activity of fertilizer on the crop, temporary crop response may result when liquid nitrogen is used as portion of the spray l"} 
carrier. Crop response symptoms due to the use of liquid nitrogen as a portion of the spray carrier may include reduced wheat growth, l., 
discoloration, and leaf bum. 
APPLICATION INFORMATION 
Properly calibrated ground or aerial (fixed wing or helicopter) application equipment may be used to apply OLYMPUSTM FLEX 
Herbicide postemergence as a foliar spray. Do not apply pre-emergence to wheat or crop response may occur. Application should be 
made after the crop has fully emerged (fully expanded first true leaf) and before grass weeds tiller. Weed infestations should be treated 
before they become competitive with the crop. 
Thorough coverage of weeds is necessary to achieve good weed control. The use of nozzles and spray pressure that deliver MEDIUM 
spray droplets as indicated in the nozzle manufacturer's catalogs and in accordance with ASAE Standard S-572 are highly 
recommended for optimum spray coverage and canopy penetration. 
Select spray nozzles that provide best spray distribution and weed coverage at the appropriate spray pressure. Avoid uneven spray 
distribution, skips, overlaps, and spray drift. 
Do not apply OLYMPUSTM FLEX Herbicide through any type of irrigation system. 
Apply OLYMPUSTM FLEX Herbicide to wheat from emergence (fully expanded first true leaf) up to jointing. Do not apply more than a 
total of 3.5 ounces/acre of OLYMPUSTM FLEX Herbicide per crop year. 
GROUND APPLICATION 
OLYMPUSTM FLEX Herbicide can be applied broadcast in 10 or more gallons of water per acre. For weed control in dense weed 
canopies, use 15 or more gallons of water per acre. Weed infestations should be treated before they become competitive with the crop. 
The use of 8O-degree or 110-degree flat-fan nozzles is highly recommended for optimum spray coverage and canopy penetration. To 
achieve uniform spray coverage, use nozzles and pressure that deliver MEDIUM spray droplets as indicated in nozzle manufacturer's 
catalogs and in accordance with ASAE standard S-572. Use screens that are 50 mesh or larger. 
AERIAL APPLICATION 
OLYMPUSTM FLEX Herbicide should be applied in a minimum of 5 gallons of water per broadcast acre. Weed infestations should be 
treated before they become competitive with the crop. 
To achieve uniform spray coverage, use nozzles and pressure that deliver MEDIUM spray droplets as indicated in nozzle 
manufacturer's catalogs and in accordance with ASAE standard S-572. DO NOT use raindrop nozzles. 
Aerial applications with this product should be made at a maximum height of 10 feet above the crop with low drift nozzles at a maximum 
pressure of 40 psi. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may 
occur. 
Flagmen and loaders should avoid inhalation of spray mist and prolonged contact with skin. 
See the SPRAY DRIFT MANAGEMENT section of this label for additional information on proper application of OLYMPUSTM FLEX 
Herbicide. 
MIXING INSTRUCTIONS 
OLYMPUSTM FLEX Herbicide must be applied with clean and properly calibrated equipment. Prior to adding OLYMPUSTM FLEX 
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 the appropriate rate of OLYMPUSTM FLEX Herbicide, as determined under the USE RATES section, directly to the spray tank. 
Maintain sufficient agitation during both mixing and application. OLYMPUSTM FLEX Herbicide should be fully dispersed in water 
before adding any other material. 
3. Add the broadleaf weed herbicide. 
4. Add the surfactant. 
5. Fill the spray tank with balance of water needed. 
6 Continue agitation during OLYMPUSTM FLEX Herbicide application to ensure uniform spray coverage. If the mixture is not 
continuously agitated, settling may occur. If settling occurs, thoroughly re-agitate spray solution for at least 10 minutes before 
application. Use spray solution within 24 hours after mixing. 
RE-SUSPENDING WG PRODUCTS IN SPRAY SOLUTION 
\..ike other Water Dispersible Granules or suspension concentrates (SC's), OL YMPUSTM FLEX Herbicide will settle if left standing 
without agitation. If the spray solution is allowed to settle for one hour or more, re-agitate the spray solution for a min:mum of 15 
minutes before application. 
COMPATIBILITY 
If OLYMPUSTM FLEX Herbicide is to be tankmixed with other herbicides, compatibility should be testea~riorto mixi;lg. To test for 
compatibility, use a small container and mix a small amount (0.5 to 1 quart) of spray solution, combining all in'grcdients in thci!Jarne ratio 
as the anticipated use. If any indications of physical incompatibility develop, do not use this mixture_. fors~raying.l:1C!izations of 
incompatibility usually occur within 5-15 minutes after mixing. Indications of incompatibility include separajionjn the mix,and either 
clumping or clabbering of the mixture. Read and follow the label of each tankmix product used for precau~i\),"ji:iry statem~nts, jirections

for use, geographic and other restrictions. 
WEEDS CONTROLLED 
OLYMPUSTM FLEX Herbicide effectively controls the following weeds when applied at the appropriate rate and application timing and 
weeds are emerged and actively growing at time of application. Best control is achieved when grass weeds are treated at the 1-leaf to 
2-tiller stage of growth and before broad leaf weeds are larger than 2 inches in diameter.

USE RATES 
Apply OLYMPUSTM FLEX Herbicide at a rate of 3.0 oz per acre in the fall or spring. Do not use less than 3.0 oz per acre unless 
directed by a Bayer CropScience Representative. 
Under dry conditions or in dense weed canopies, use 3.5 oz per acre for best results. 
In Washington, Oregon, and Idaho, use 3.5 oz per acre for all grass species except for wild oat and windgrass. For control of wild oat 
and windgrass, 3.0 oz per acre may be used. 
TIMING OF APPLICATION 
Apply OL YMPUSTM FLEX Herbicide from first fully expanded true leaf up to jointing. 
TANKMIXES 
For broad-spectrum control of both annual grasses and broadleaf weeds, OLYMPUSTM FLEX Herbicide may be mixed with broadleaf 
herbicides and an appropriate adjuvant. OLYMPUSTM FLEX Herbicide contains 0.091 pounds of mefenpyr-diethyl pound of product. 
Applying the maximum labeled rate of OL YMPUSTM FLEX Herbicide delivers 0.020 Ibs of mefenpyr-diethyl per acre. Do not apply more 
than 0.053 pounds of mefenpyr-diethyl per acre per year. With all tankmix partners, read and follow use directions, rates, precautions, 
timing, recropping restrictions, grazing interval restrictions and recommendations on the broadleaf herbicide and surfactant labels. It is 
recommended that products not specifically listed on this label for tankmixing with OL YMPUSTM FLEX Herbicide be applied 
sequentially, 7 days prior to or 7 days after an OLYMPUSTM FLEX Herbicide treatment. 
When tank mixing with EC broadleaf herbicides, frost occurrence the night before or within two nights after application may increase 
crop response. These effects can be quite marked when OLYMPUSTM FLEX Herbicide is tankmixed with EC partners. Additionally, 
abnormally large temperature fluctuations between daytime highs and nighttime lows reduce the crop tolerance of these combinations. 
Avoid the tank mixing of EC broad leaf herbicides with Olympus Flex under these environmental conditions or wait until conditions 
moderate. When tank mixing Olympus Flex with an EC broadleaf herbicide in Washington, Oregon, and Idaho, reduce the NIS rate 
from 0.5% to 0.25%.

TANK CLEANUP PROCEDURE 
1. Drain the tank completely, and then wash out tank, boom and hoses with clean water. Drain again. 
2. Fill the tank half full with clean water and add ammonia (Le., 3% domestic ammonia solution) at a dilution rate of 1% (Le., 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. Continue agitation 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. 
CROP ROTATION RESTRICTIONS 
OL YMPUSTM FLEX Herbicide breakdown in the soil is due mainly to microbial activity. It can be affected by soil temperature and 
moisture. Conditions that accelerate the breakdown of OL YMPUSTM FLEX Herbicide include adequate soil moisture and adequate soil 
temperatures to support microbial activity. Likewise, OLYMPUSTM FLEX Herbicide breakdown can be slowed under dry, cold 
conditions. When considering crop rotations, soil moisture and soil temperature conditions following application should be monitored.

described in the FIELD BIOASSAY section of this label. In all areas, 24 inches of rainfall and a 24 month rotation interval are required \ 
for potatoes, buckwheat, onions, oats, dry beans, alfalfa, and sugarbeets. 
Rotational crops should not be planted on clay or eroded hillsides following an OL YMPUSTM FLEX Herbicide application without 
conducting a field bioassay. 
FIELD BIOASSAY 
A field bioassay must be conducted for crops not listed on this label and for crops where the cumulative precipitation requirements are 
not satisfied or for crops listed on the label for which a shorter plant-back interval than listed is desired. 
To conduct a field bioassay, plant strips of the crop you want to grow the season follOwing OLYMPUSTM FLEX Herbicide application. 
Monitor the crop for response to OL YMPUSTM FLEX Herbicide to determine if the crop can be grown safely in previously treated 
OL YMPUSTM FLEX Herbicide areas. 
Regardless of the bioassay results, do not plant any crop, except fall-sown or winter wheat, closer than 4 months after an OLYMPUSTM 
FLEX Herbicide application. 
WEED RESISTANCE 
OL YMPUSTM FLEX Herbicide is an acetolactate synthase (ALS) inhibiting herbicide. Some weed populations may contain plants 
naturally resistant to OLYMPUSTM FLEX Herbicide or other herbicides with same mode of action (ALS/AHAS enzyme inhibitors). 
Repeated use of herbicides with the same mode of action allows resistant weeds to spread. To manage the spread of resistant weed 
populations, use herbicides with different modes of action in tankmixture, rotation, or in conjunction with alternate cultural practices. 
The use of OLYMPUSTM FLEX Herbicide should conform to resistance management strategies established for the use area. Consult 
your agricultural advisor for resistance management strategies and recommended pest management practices for your area. 
SPRAY DRIFT MANAGEMENT 
OLYMPUSTM FLEX Herbicide is not volatile. Damage to sensitive crops can occur as a result of spray drift. Spray drift can be 
managed by several application factors and by spraying under the appropriate climatic conditions. Consequently, avoidance of spray 
drift is the responsibility of the applicator and grower. 
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 habitats for threatened or endangered species, non-target crops) is minimal (e.g., when wind is blOwing 
away from the sensitive areas). 
Avoiding spray drift at the application site is the responsibility of the applicator and grower. 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. 
Do not apply under circumstances where possible drift to unprotected persons or to food, forage, or other plantings that might be 
damaged or crops thereof rendered unfit for sale, use or consumption can occur. 
The following drift management requirements must be followed to avoid Off-target drift movement from aerial applications to agricultural 
field crops. 
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. 
3. All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers. 
Where states have more stringent regulations, they shall be observed. The applicator should be familiar with and take into account the 
information covered in the Aerial Drift Reduction Advisorv Information. 
INFORMATION ON 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 Inversions below). 
Uniform, thorough spray coverage is important to achieve consistent weed control. Select nozzles and pressure that deliver MEDIUM 
spray droplets as indicated in nozzle manufacturer's catalogs and in accordance with ASAE Standard S-572. Nozzles that deliver 
COARSE spray droplets may be used to reduce spray drift provided spray volume per acre (GPA) is increased to maintain coverage of 
weeds. 
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 - Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle t'j~c:: ~cwer pre:.;~ure produces 
larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasir.g pr~s'1ure. 
• Number of nozzles - Use the minimum number of nozzles that provide uniform coverage. 
• Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the airstream produce..:; larger droolet!'; than other 
orientations and is the recommended practice. Significant deflection from horizontal will reduce droplet size al,d ;ncrt:lase drift 
potential. 
a

10 -• Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles l 'L 
produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce the largest droplets 
arid the lowest drift. 
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 HEIGHT: 
Applications should 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. 
For ground boom applications, apply with nozzle height no more than 4 feet above the ground or crop canopy. 
SWATH ADJUSTMENT: 
When applications are made with a crosswind, the swath will be displaced downward. 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.) 
WIND: 
Drift potential is lowest between wind speeds of 2 - 10 mph. However, many factors, including droplet size and equipment type 
determine drift potential at any given speed. Application should 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 spray drift. 
For all non-aerial applications, wind speed must be measured adjacent to the application site, on the upwind side, immediately prior to 
application. 
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. Avoid spraying during conditions of low humidity and/or high 
temperatures. 
TEMPERATURE INVERSIONS: 
Do not make aerial or ground applications into areas of temperature inversions 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 temperatures 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 concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and 
rapidly dissipates indicates good vertical air mixing. 
ENDANGERED SPECIES 
To avoid adverse effects on endangered plant species, the following mitigation measures will be required where endangered species 
occur in Counties listed in the table on the following page. 
For ground applications, the applicator must: 
1. Apply when there is sustained wind away from native plant communities, OR 
2. Leave 50 foot untreated buffer between treatment area and native plant communities. 
For aerial applications, the applicator must: 
1. Apply only when there is sustained wind away from native plant communities, OR 
2. Leave 350 foot untreated buffer between treatment area and native plants.

PRECAUTIONS FOR USE 
• Use adjuvants as specified on this label. 
• Do not apply OL YMPUSTM FLEX Herbicide to crops undersown with grass and legume species. 
• OLYMPUSTM FLEX Herbicide is rainfast 4 hours after application to most weed species. Rainfall within 4 hours may result in 
reduced weed control. 
• Applications should be made to actively growing weeds. Weed control may be reduced when weeds are under stress due to 
severe weather conditions, drought, very cold temperatures, etc. Weed control may be reduced if the herbicide application is made 
under dry, dusty conditions - especially in the wheel track areas. 
• Do not make more than one application of OL YMPUSTM FLEX Herbicide in one growing season. 
• Do not apply more than 3.5 ozlacre of OLYMPUSTM FLEX Herbicide in one growing season. 
• Do not apply more than 0.053 pounds of mefenpyr-diethyl per acre per year. 
• Do not apply when wind causes drift to off-site vegetation as injury may occur. Small amounts of OL YMPUSTM FLEX Herbicide via 
drift or tank contamination can cause severe response to crops other than fall-sown or winter wheat. Careful management of spray 
drift and tank cleanout is required. 
• Wheat may be harvested for forage after 30 days or grain and straw 71 days after an OL YMPUSTM FLEX Herbicide application. 
• Do not apply OL YMPUSTM FLEX Herbicide in tankmixture with malathion, mancozeb, phosphorodithioate (Di-Systor,~ crlorpyrifos 
(Lorsban™), or methyl parathion as unacceptable crop response may occur. 
• Do not use in San Luis Valley, CO.
