PRODUCT INFORMATION
Apply OMNI BRAND T-METHYL 4.5F by ground or aerial application equipment using sufficient volume of
spray to provide thorough coverage. Normal fungicide usage indicates this product will be applied over the
top of the intended crop; it is critical to ensure that the tank and spray equipment has been cleaned of all
other pesticides prior to mixing this product. Continuous agitation is required to keep the ingredients in
suspension. Application gallonage and directions are given for each crop.
OMNI BRAND T-METHYL 4.5F may be tank mixed with other fungicides, insecticides and plant growth
regulators that have been approved for use by the EPA on the registered crops. Helena Chemical Company
does not make any claims of compatibility with other pesticides; always perform a Mixing Jar Test prior to
tank mixing. See Compatibility Test section on this label. Do not tank mix with highly alkaline pesticides,
such as Bordeaux mixture or lime sulfur.
Omni Brand T-Methyl 4.5F (5905-ANI) 110817 CLN.docx 4
Most effective disease control is obtained by preventative spray timing as climatic conditions indicate fungal
infection or growth is imminent. Always use the higher rates under conditions of severe disease pressure.
Also, see local State Extension Service directions for application schedules.
Use on non-bearing apples, pecans, cherries, and peaches: OMNI BRAND T-METHYL 4.5F may be used
for control of the leaf diseases listed on the label for these crops during the non-bearing years of new
plantings, and on nursery stock. All use directions and limitations must be followed, except for the PHI,
which is not applicable. Begin applications as disease is first observed. Tank mixing with a protectant
fungicide is strongly recommended for resistance management.
High volume dilute applications: Use the PRODUCT per ACRE rate for concentrate spray applications
for tree crops (example: no more than 400 gallons on apples). When making dilute ground applications,
use the PRODUCT per 100 GALLONS rate. Follow all crop specific language on this label for application.
Dilute sprays must not exceed maximum a.i. per year.
Aerial applications to tree crops: Use a minimum of 10 gal/acre for aerial application to fruit tree crops.
Increased fungicidal activity is related to coverage and timing, increased volumes are required as crop
canopy density increases. NOTE: Conifer applications require higher spray volumes, use lower volumes
with mist type applicators and highest volumes with conventional types.
Row Crop applications: Use a minimum of 5 gal/acre for ground application, however make most ground
applications with 10 to 20 gal/acre as cropping situations dictate. Increased fungicidal activity is related to
coverage and timing, increased volumes are required as crop canopy density increases.
Plantback Restriction: Do not plant any crop not labeled for OMNI BRAND T-METHYL 4.5F use within
30 days of the last application.
Chemigation: See specific directions in this label.
Mode of Action: OMNI BRAND T-METHYL 4.5F is a tubulin inhibitor fungicide falling into the FRAC Group
1 for Benzimidazoles. Its Mode of Action is the inhibition of microtubule assembly. It has protectant,
systemic and curative actions, each of these specific to certain crops, fungi and climatic conditions.
Fungicide Resistance: Fungal pathogens have proven to develop a resistance to certain fungicide
families and modes of action. These are called tolerant and resistant strains of fungi. Industry and university
research have developed effective programs that continue to provide excellent control of these strains,
however, precautions and specific steps must be taken to ensure effective fungicide rotation, tank mixing
of different modes of action and disease monitoring are the keys of your fungicide program.
Rotate or tank mix OMNI BRAND T-METHYL 4.5F different modes of action fungicide chemistry. All
products containing thiabendazole and thiophanate ethyl fungicides (benzimidazole fungicides) are NOT
considered rotation or tank mix partners. These utilize similar chemistry and mode of action and can
contribute to development of disease tolerance.
Should OMNI BRAND T-METHYL 4.5F be applied as directed and the treatment is considered not to be
effective, you may have encountered a resistant or to lerant fungi strain. Do not apply this mode of action
chemistry again during this year, as this may enhance the resistance at this site. Consult with your local
Cooperative Extension Service, University Research or Certified Crop Consultant for more information
concerning fungicides effective on the tolerant or resistant strains encountered.
MIXING INSTRUCTIONS
Determine the treatment rate as indicated in the directions for use for crop and pathogen and measure the
intended areas of application. Prepare a suspension of product. Fill spray tank to half full, start agitation.
See Mixing Order chart below when any other products are tank mixed with this product. Be sure to shake
product container well before pouring to measure. Some settling may occur during prolonged periods of
Omni Brand T-Methyl 4.5F (5905-ANI) 110817 CLN.docx 5
non-use. High pH environments cause a shortened tank life for diluted product. Buffer tank water to pH 6-
7 prior to the addition of OMNI BRAND T-METHYL 4.5F. Slowly pour required product into partially filled
spray tank (1/2 total volume), then finish filling tank with water, all the while maintaining agitation. Use
sufficient water to ensure full coverage of foliage. Do not use an amount of water that could lead to
excessive runoff from target plants. The amount of water will vary according to the amount of foliage
requiring coverage and type of equipment but generally 25 to 100 gallons per acre is adequate. If there is
any question as to the compatibility of the components, always perform a jar test with proportional amounts
of each product, using water from the actual use source.
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.
Do not mix more spray solution than you plan to apply that day.
Tank Mixing Instructions
OMNI BRAND T-METHYL 4.5F is compatible with most commonly used pesticides. If tank mixing with
other materials, add products in the following order: water soluble bags, wettable powders, dry flowables,
liquid flowables, emulsifiable concentrates, and soluble materials such as fertilizers. No claim of
compatibility with other products is implied. Do not tank mix with copper-containing materials or highly
alkaline pesticides, such as Bordeaux mixture or lime sulfur. Consult the intended tank mix partner
product label for appropriate application rates and use instructions. Follow the label directions for the most
restrictive of label precautions and limitations. This product cannot be mixed with any product containing a
label prohibition against such mixing. Read and observe the most restrictive precautionary statements and
other information appearing on product labels used in mixtures. OMNI BRAND T-METHYL 4.5F may be
applied in conjunction with chemically neutral liquid fertilizers. Avoid application in conjunction with highly
alkaline fertilizers, such as aqueous ammonia, as this may cause a degradation of the pesticide, resulting
in reduced performance.
Compatibility Test for Mix Components
Before mixing components, always perform a compatibility jar test. 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. Add components in the sequence indicated in the Mixing
Order using 2 teaspoons for each pound or 1 teaspoon for each pint of specified label rate per acre. Always
cap the jar and invert 10 cycles between component additions.
When the components have all been added to the jar, let the solution stand for 15 minutes. Evaluate the
solution for uniformity and stability. The spray solution should not have free oil on the surface, nor fine
particles that precipitate to the bottom, nor 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
NOTE: As each product is added to the tank, be sure it is completely dispersed before adding any other
product to the mix. Maintain agitation throughout mixing and application processes.
1) Water. Begin by agitating a thoroughly clean sprayer tank three-quarters full of clean water.
2) Agitation. Maintain constant agitation throughout mixing and application.
3) Inductor. If an inductor is used, rinse it thoroughly after each component has been added.
4) 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.
5) Water-dispersible products (such as, dry flowables - DF, wettable powders - WP, wettable dry granules
WDG, suspension concentrates - SC, or suspo-emulsions - SE).
6) Water-soluble products.
7) Emulsifiable concentrates (such as oil concentrate when applicable).
Omni Brand T-Methyl 4.5F (5905-ANI) 110817 CLN.docx 6

FUNGICIDE DILUTION MIX PREPARATION
Clean all chemical mix tank, induction lines, mixing and induction motors and pumps of any prior use
pesticide residues, scale or other foreign matter that may interfer with mixing or transfer of the pesticide
dilution into the irrigation system. Flush with clean water.
Start by filling the mix tank at least ½ full. Begin ag itation. Carefully add the required amount of OMNI
BRAND T-METHYL 4.5F and then the rest of the water. Allow time to mix completely.
APPLICATION INSTRUCTIONS
Observe ALL requirements in the System Requirements section above. Remove scale, pesticide residue,
and other foreign matter from the chemical tank and entire injector system. Flush with clean water.
In order to ensure a uniform pesticide suspension and application, be sure to continuously agitate the
fungicide tank-mixture during mixing and application.
Inject a greater volume of a more dilute suspension per unit time in order to achieve greater accuracy in
distribution and calibration.
NOTE: An injection ratio of 1:100 is directed for greenhouse systems.
Do not apply more irrigation water per acre than directed, decreased product performance may occur from
the over diluted application. Determine the treatment rate as indicated in the directions for use for crop and
pathogen and measure the intended areas of application.
Prepare a suspension of product in the mix tank or stock bucket. Fill the tank with 1/2 or 3/4 of the desired
amount of water. Start agitation and add the required amount of product to the solution along with the
remaining volume of water. Use sufficient water to ensure full coverage of foliage. Do not use an amount
of water that could lead to excessive runoff from target plants. The amount of water will vary according to
the amount of foliage requiring coverage and type of equipment but generally 25 to 100 gallons per acre is
adequate.
Chemigation must not be attempted when wind speed favors drift. When system connections or fittings are
seen to leak, stop chemigation and repair the component prior to restart. When nozzles are not providing
uniform distribution, recalibrate immediately. System must always remain in good repair.
When chemigation is completed, allow sufficient flush time for pesticide to be cleared from all nozzles and
lines prior to shutting off the flow of irrigation water.
Fertilizer co-mix Instructions:
You may mix and apply this product with other chemically-neutral liquid fertilizers. However, the
applicator should be aware that mixing this product with highly alkaline fertilizers (such as aqueous
ammonia) may cause problematic degradation of this product. Such a mix may prevent optimum control.
Sprinkler Irrigation Instructions:
Observe all System Requirements and Application Instructions above.
Always observe local irrigation restrictions or ordinances.
Repair overhead irrigation systems to block the spray jets or nozzles nearest the operations control
panels as to not allow treated water to contact the operator or operation station
.

APPLICATION INSTRUCTIONS:
Apply material with properly calibrated, hand held, mechanical or motorized spray equipment or by
chemigation through appropriate sprinkler irrigation, flood, or drip systems. Begin applications when
disease first appears and repeat at 7-14 day intervals or as needed during the growing season. Use the
shortest interval when conditions are unusually favorable for the development of disease. For hand held,
mechanical, or motorized applications, mix 8-24 oz of THIOPHANATE METHYL 4.5L per 100 gal water
(0.5-1.5 teaspoons per gal) and apply as a full coverage spray to drip for the prevention and control of the
diseases listed below. Spray volume may range up to 400 gallons of finished spray per acre depending
upon plant species and plant growth stage. For applications through irrigations systems, refer to use rates
indicated in the foliar application chart. For small volume applications less than 100 gallons, divide directed

Hydraulic Application Mixing Instructions
Add the required amount of Omni Brand T-Methyl 4.5F to a partially filled spray tank agitated by mechanical
or hydraulic means and then add the remaining volume of water. Maintain continuous agitation to keep the
material in suspension and apply with properly calibrated spray equipment.
Application Concentrations (Mechanical or Hand-Held):
Use the labeled amount of Omni Brand T-Methyl 4.5F per 100 gallons of water for the prevention and
control of the diseases shown below.
Special Instructions For Proportional Injectors (e.g. Dosatron, Dosmatic, Anderson, and similar
equipment):
Determine the treatment rate for crop and pathogen from the foliar application table below. Determine the
injection ratio for the individual system to be used for application. For systems using a 1:100 ratio, measure
and add the exact amount of specified material per 100 gallons to each gallon of water in a stock bucket or
tank. For systems using a 1:200 ratio, multiply the specified amount per 100 gallons by 2. For systems
using a 1:50 ratio, divide the specified amount per 100 gallons added by 2. For systems using 1:16 ratio,
divide the directed amount per 100 gallons by 6. Greater accuracy in calibration and distribution will be
achieved by injecting a larger volume of a more dilute suspension per unit time. For greenhouse and
nursery systems use an injection ration of 1:100.
RESTRICTION: Do not apply more than 3.0 lbs AI per year.
