FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS
LABEL MAY RESULT IN CROP INJURY, POOR INSECT AND/OR DISEASE
CONTROL, AND/OR ILLEGAL RESIDUES.
Treatment of highly mechanically scarred or damaged seed, or seed known to be of low
vigor and poor quality may result in reduced germination and/or reduction of seed and
seedling vigor. Treat a quantity of seed using equipment similar to that planned for
treating the total seed lot. Prior to treatment, conduct germination tests on a portion of
seed before committing the total seed lot to a selected seed treatment.
Due to seed quality, crop or variety sensitivity, and seed storage conditions beyond the
control of Syngenta, no claims are made to guarantee the germination of seed or
propagating material for all crop seed when treated with Four-way VAP.
USE INFORMATION
Four-way VAP is a seed treatment product containing the active ingredients:
thiamethoxam (insecticide) and azoxystrobin, fludioxonil and mefenoxam fungicides.
Four-way VAP protects against damage from listed early season insects, soil-borne and
seed-borne diseases of crop plants.
Thiamethoxam is a systemic seed treatment insecticide belonging to the neonicotinoid
class of chemistry. Thiamethoxam protects against listed chewing and sucking insects
through contact and ingestion.
Mefenoxam fungicide is active against Pythium, Phytophthora and systemic downy
mildew.
Fludioxonil fungicide is active against Fusarium, Rhizoctonia, and suppresses seed-
borne Sclerotinia and Phomopsis species.
Azoxystrobin is active against Rhizoctonia and some seed-borne diseases.
MIXING PROCEDURES
Important: Always re-circulate Four-way VAP thoroughly before using.
Apply Four-way VAP as a water-based slurry utilizing standard slurry seed treatment
equipment which provides uniform seed coverage. Uneven or incomplete seed
coverage may not give the desired level of disease control. Thoroughly mix the
specified amount of Four-way VAP into the required amount of water or liquid inoculant
for the slurry treater and dilution rate to be used.
Certain crops require addition of inoculants when the seed is treated or planted. Four-
way VAP is compatible with several liquid inoculant products. Consult the maker of the
-8-
inoculant product and a Syngenta Crop Protection representative for directions before
applying Four-way VAP with inoculants.
Under certain disease conditions, additional amounts of fungicides may be required.
When needed, apply additional Apron XL® according to the CROP USE DIRECTIONS.
Other tank mix partners may be used with Four-way VAP; however, the user must
consider the use rate, formulation, seed and crop safety factors and compatibility of
each product to be mixed when determining the total application volume.
The total application volume must be sufficient to provide desired level of coverage.
Dilution is typically done with water or liquid inoculants. The minimum slurry volume to
achieve adequate coverage is 4.0 fluid ounces per 100 pounds of seed. More diluent
may be required to obtain complete coverage.
Continuous agitation or mixing of the slurry mixture is necessary to prevent settling out
of the solution.
Allow seed to dry before bagging.
The typical density of Four-way VAP is 9.43 pounds per gallon. Consult the
manufacturer of the application equipment you plan to use for suitability for this
application and for instructions on operation and calibration of the equipment. Follow
the manufacturer application instructions for the seed treatment equipment being used.
Follow planter manufacturer specifications for use of talc or other hopper box additives
at planting. Seed must be completely dry before adding to planter.
Four-way VAP contains an EPA approved dye/colorant that imparts an unnatural color
to the seed as stated in 40 CFR 153.155 (c).

CROP USE PRECAUTIONS
Resistance Management
MEFENOXAM GROUP 4 FUNGICIDE
AZOXYSTROBIN GROUP 11 FUNGICIDE
FLUDIOXONIL GROUP 12 FUNGICIDE
For resistance management, please note that Four-way VAP contains Group
4/mefenoxam, Group 11/azoxystrobin, and Group 12/fludioxonil fungicides. Any fungal
population may contain individuals naturally resistant to Four-way VAP and other Group
4, Group 11, or Group 12 fungicides. A gradual or total loss of pest control may occur
over time if these fungicides are used repeatedly in the same fields. Appropriate
resistance-management strategies should be followed.
Mefenoxam belongs to the phenylamide class of chemistry which interferes with fungal
RNA synthesis. Azoxystrobin belongs to the strobilurin class of chemistry which disrupts
cellular respiration and energy generation. Fludioxonil belongs to the phenylpyrrole
class of chemistry which interferes with osmotic signal transduction.
To delay fungicide resistance, take one or more of the following steps:
x Rotate the use of Four-way VAP or other Group 4, Group 11, or Group 12 f ungicides
within a growing season sequence with different groups that control the same
pathogens.
x Use tank mi xt ur es wi th f ungi ci des f r om a di f f er ent gr oup that ar e equal l y ef f ecti ve on
the target pest when such use is permitted. Use at l east the mini mum application
rate as l abel ed by the manufacturer.
x Adopt an integrated disease management program for f ungicide use that includes
scouting, uses historical information related to pesticide use, and crop rotation, and
which considers host plant resistance, impact of environmental condi tions on
disease development, disease thresholds, as well as cultural, biological and other
chemi cal contr ol pr acti ces.
x Where possi ble, make use of predictive disease models to effectivel y time fungicide
applications. Note that using predictive model s alone is not sufficient to manage
resi stance.
x M onitor treated fungal populations for resistance development.
x Contact your local extension specialist or certified crop advisor for any additi onal
pesticide resistance-management and/or IPM recommendations for specific crops
and pathogens.
x For further i nformation or to report suspected resistance contact Syngenta at 1-866-
SYNGENT(A) (866-796-4368). You can also contact your pesticide distributor or
university extension specialist to report resistance.

Syngenta encourages responsible product stewardship to ensure effective long-term
control of the fungal diseases on this label.
THIAMETHOXAM GROUP 4A INSECTICIDE
Four-way VAP contains a Group 4A insecticide (thiamethoxam, belonging to the
neonicotinoid class of chemistry). Insect biotypes with acquired or inherent resistance
to Group 4A insecticides may eventually dominate the insect population if Group 4A
insecticides are used repeatedly as the predominant method of control for targeted
species. This may result in partial or total loss of control of those species by Four-way
VAP or other Group 4A insecticides.
Thiamethoxam is a systemic insecticide belonging to the neonicotinoid class of
chemistry which includes nicotinic acetylcholine receptor (nAChR) agonists.
In order to maintain susceptibility to this class of chemistry:
x Avoid using Group 4A insecticides exclusively for season long control of insect
species with more than one generation per crop season.
x For insect species with successive or overlapping generations, apply Four-way VAP
or other Group 4A insecticides using a “treatment window” approach. A treatment
window is a period of time as defined by the stage of crop development and/or the
biology of the pests of concern. Within the treatment window, depending on the
length of residual activity, there may either be single or consecutive applications
(seed treatment, soil, foliar, unless otherwise stated in the Directions for Use) of the
Group 4A insecticides. Do not exceed the maximum Four-way VAP allowed per
growing season.
x Following a treatment window of Group 4A insecticides, rotate to a treatment window
of effective products with a different mode of action before making additional
applications of Group 4A insecticides.
x A treatment window rotation, along with other IPM practices for the crop and use
area, is considered an effective strategy for preventing or delaying a pests ability to
develop resistance to this class of chemistry.
x If resistance is suspected, do not reapply Four-way VAP or any other Group 4A
insecticides.
Other Insect Resistance Management (IRM) practices include:
ƒ Incorporating IPM techniques into your insect control program.
ƒ Monitoring treated insect populations for loss of field efficacy.
ƒ Using tank-mixtures or premixes with insecticides from a different target site of
action group as long as the involved products are all registered for the same crop
outlet and effective rates are applied.
For additional information on Insect Resistance Management:
ƒ Contact your local extension specialist, certified crop advisor and/or product
manufacturer for additional insect resistance management recommendations.

When applied according to the FOUR-WAY VAP RATE TABLE, Four-way VAP
provides early season protection against injury by aphids, bean leaf beetle, grape
colaspis, leaf miners, leaf hoppers, Mexican bean beetle, seed corn maggot,
threecornered alfalfa hopper, thrips, white grubs, and wireworm.
Four-way VAP provides protection against damping-off and seed borne rots due to
Pythium, Phytophthora, Fusarium, Rhizoctonia species and early season Phytophthora
root rot. Four-way VAP also suppresses seed-borne Sclerotinia and Phomopsis
species.

When to add additional Apron XL:
If target fields have a history of high Phytophthora pressure, add additional Apron XL as
directed in the rate table and the Apron XL label. The additional Apron XL may reduce
compatibility with some rhizobia inoculants. Consult with the maker of rhizobia
inoculants before adding the additional Apron XL.

NOTE:
x Under cool conditions at planting, azoxystrobin has been documented in some geographies to delay emergence of certain varieties within the
Legume Vegetable Group.
x Due to the large number of varieties within the Legume Vegetable Group, some varieties have not been evaluated for seed safety. If the Four-
way VAP seed safety of a particular variety is unknown, a seed safety germination study should be conducted prior to applying Fo ur-way VAP.
x When treated according to the directions for post-planting protection against listed pests, Four-way VAP will also provide prote ction during
post treatment storage of the seed against damage from the following stored grain insects: Indian Meal Moth ( Plodia interpunctella), Rice
Weevil (Sitophilus oryza), Red Flour Beetle (Tribolium castaneum), and Lesser Grain Borer (Rhizopertha dominica).
x If seed to be treated has existing infestations of stored grain insects, it is recommended that the seed be fumigated prior to treating with Four-
way VAP and bagging.
