3.0 PRODUCT INFORMATION

Read all label directions before use. All applications must be made according to the use
directions that follow.

 Hyetal contains mandipropamid and is for the control or suppression of the diseases listed
on this label.
 Hyetal provides control of diseases caused by oomycete plant pathogens. It has
preventative and limited curative properties.
 Hyetal, when applied as a foliar spray and can be us ed in block, alternating spray, or tank
mix programs with other crop protection products.
 See Section 7.0 for specific crop/disease directions.


Disease Suppression: If a use indicates suppression it refers to erratic control from fair to
good, or consistent control at a level below that obtained with products registered for control.

Hyetal
Page 7

Mode of Action: Hyetal contains mandipropamid, which inhibits cellulose synthesis in the
oomycete plant pathogens.

Crop Tolerance: Not all crops within a crop group, and not all varieties, cultivars or hybrids
of crops have been individually tested for crop safety. It is not possible to evaluate for crop
safety all applications of Hyetal on all crops within a crop group, on all varieties, cultivars, or
hybrids of those crops, or under all environmental conditions and growing circumstances. To
test for crop safety, apply the product in accordance with the label instructions to a small area
of the target crop to ensure that a phytotoxic response will not occur, especially where the
application is a new use of the product by the applicator


3.1 Resistance Management

For resistance management, please note that Hyetal contains a Group 40 (mandipropamid)
fungicide. Any fungal population may contain individuals naturally resistant to the active
ingredients in Hyetal and other Group 40 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.

To delay fungicide resistance, take one or more of the following steps:
 Rotate the use of mandipr opamid or other Group 40 fungicides within a growing season
sequence with different groups that control the same pathogens.
 Use tank mixtures with fungicide from a di fferent group that are equally effective on the
target pest when such use is permitted. Use at least the minimum application rate as
labeled by the manufacturer.
 Adopt an integrated diseas e management program for fungicide use that includes
scouting, uses historical information related to pesticide use, and crop rotation, and which
considers host plant resistance, impact of environmental conditions on disease
development, disease thresholds, as well as cultural, biological and other chemical control
practices.
 Where possible, make use of predictive disease models to effectively time fungicide
applications. Note that using predictive models alone is not sufficient to manage
resistance.
 Monitor treated fungal populati ons for resistance development.
 Contact your local extension specialist or ce rtified crop advisor for any additional pesticide
resistance-management and/or IPM recommendations for specific crop and pathogens.
 For further information or to report suspected resistance contact Syngenta Crop Protection
at 1-866-796-4368. You can also contact your pesticide distributor or university extension
specialist to report resistance.

As part of a resistance management strategy:
 Apply a maximum of 4 sprays during one crop cycle.
 Apply no more than 2 sequentia l applications unless otherwise stated in the crop section.
 When tank mixing or alternating, use an effect ive partner – one that provides satisfactory
disease control when used alone at the mixture rate.
 DO NOT use Hyetal in vegetable transplant production.

3.2 Integrated Pest Management (IPM)
Syngenta advises the use of Integrated Pest Management (IPM) programs to control pests.
Hyetal may be used as part of an IPM program which can include biological, cultural, and
genetic practices aimed at preventing economic pest damage. Application of this product
should be based on IPM principles and practices including field scouting or other detection
methods, correct target pest identification, population monitoring, and treating when disease
forecasting models reach locally determined action levels. Consult your state cooperative
extension service, professional consultants, or other qualified authorities to determine the
appropriate management, cultural practice and treatment threshold levels for the specific
crop, geography, and diseases.
4.0 APPLICATION DIRECTIONS

4.1 Methods of Application
 Hyetal may be applied with all types of spray equipment commonly used for making
ground and aerial applications.
 Proper adjustments and calibration of sprayi ng equipment to give good canopy penetration
and coverage is essential for good disease control.
 For suppression or control of soil-borne diseases, as specified in this label, Hyetal must be
applied in a manner that ensures the product solution adequately saturates the target crop
root/crown zone.
 When applied to the root/crown zone before, dur ing, or soon after sowing or transplanting
the crop, Hyetal will suppress or control certain seedling root rot and crown diseases that
limit crop stand establishment.
 For soil application, apply Hyetal using chem igation, transplant water application (water
wheel or continuous stream transplanters), surface band or directed application, or in-
furrow application using the rates in Table 1. See table and chemigation instructions
below.
 If the application method does no t move the product to the target root/crown disease zone,
the application must be followed with irrigation or cultivation to correctly place the product
for disease control.

4.1.1 Soil Application
In-Furrow Application
 Apply Hyetal as an in-furrow spray in 5-15 gallons water per acre at planting.
 Mount the spray nozzle so the spray is dire cted into the furrow just before the seed are
covered.

Transplant Water Application
 Transplants should be adequately watered before transplanting. Ensure transplant water
volume is sufficient to thoroughly wet the root zone.
 See Table 1 for continuous-stream transplanters. Ensure 4-8 fl oz transplant water/
transplant depending on sandy (4 fl oz) vs silty soil (6-8 fl oz).
 For water-wheel transplanters, use the plant population to determine the rate of product
per plant.

Example:
16 fl oz product x acre = 0.0036 fl oz product
acre 4,356 plants plant

Surface Band or Directed Application
 Apply in a 6- to 12-inch band. See Table 1 for rates.
 For ground broadcast application, apply in a mi nimum of 20 gallons of water per acre,
unless specified otherwise. If rain is not expected within 24 hours after application,
mechanically incorporate (before planting) or sprinkler irrigate (after planting) with 0.25-0.5
inch of water to move Hyetal into target disease zone.

recommendations.

4.2.1 Nozzles
 Equip sprayers with nozzles that provide accurate and uniform application.
 Nozzles should be the same size and uniformly spaced across the boom.
 Calibrate sprayer before use.
 It is suggested that screens be used to pr otect the pump and to prevent nozzles from
clogging.
 Screens placed on suction side of pum p should be 16-mesh or coarser.
 DO NOT place a screen in the recirculation line.
 Use 50-mesh or coarser screens between the pump and boom, and where required, at
the nozzles.
 Check nozzle manufacturer’s specifications.

4.2.2 Pumps
 Use a pump with capacity to maintain 35-40 ps i at nozzles and provide sufficient agitation
in tank to keep mixture in suspension - this requires recirculation of 10% of tank volume
per minute.
 Use a jet agitator or liquid sparge tube for agitation.
 DO NOT air sparge.

4.3 Application Volume and Spray Coverage
 Thorough coverage is necessary to provide good disease control.
 Make no more spray solution than is needed for application.
 Avoid spray overlap, as crop injury may occur.
 For aerial applications, apply in a minimum of 5 gallons of water per acre unless specified
otherwise.
 For ground applications, apply in a minimum of 10 gallons of water per acre unless

5. DO NOT let the spray mixture stand overnight or for prolonged periods of time (more than
3 hours) in the spray tank without agitation.
6. Flush the spray equipment thoroughly foll owing each use and apply the rinsate to a
previously treated area.

4.4.1 Hyetal Alone
1. Add ½- ⅔ of the required amount of water to the spray or mixing tank.
2. With the agitator running, add Hyetal to the tank.
3. Continue agitation while adding the remainder of the water.
4. Begin application of the spray solution after Hyetal has completely dispersed into the mix
water.
5. Maintain agitation until all of the mixture has been sprayed.

4.4.2 Tank-Mix Precautions
 It is the pesticide user’s responsibility to ens ure that all products are registered for the
intended use. Read and follow the applicable restrictions, limitations and directions for use
on all product labels involved in tank mixing. User must follow the most restrictive
directions for use and precautionary statements of each product in the tank mixture.
 Tank mixes of Hyetal with other pestici des, fertilizers, or any other additives not
specifically labelled for use with Hyetal may result in tank mix incompatibility or
unsatisfactory performance. In such cases, always check tank mix compatibility by
conducting a jar test according to guidance in Section 4.4.3 before actual tank mixing.
 All tank mixes should be pre-tested to determine physical compatibility between
formulations.

4.4.3 Tank-Mix Compatibility
 Conduct a jar test using a 1 pt to 1 qt cont ainer with lid by adding water or other intended
carrier such a liquid fertilizer to the jar.
 Next, add the appropriate amount of pesticides(s ) or tank-mix partner(s) in their relative
proportions based on specified label rates. Add tank-mix components separately in the
order described in the tank-mixing section, Section 4.4.4. After each addition, shake or
stir gently to thoroughly mix.
 After all ingredients have been added, put the lid on the jar, tighten and invert the jar 10
times to mix.
 After mixing, let the mixture stand 15–30 minutes and then examine for signs of
incompatibility such as obvious separation, large flakes, precipitates, gels or heavy oily
film on the jar.
 If the mixture remains mixed or can be remixed readily, it is physically compatible and can
be used.
 If the mixture is incompatible , repeat the test using a compatibility agent at the specified
label rate. Or, if applicable, slurry dry formulations in water before adding to the jar. If
incompatibility is still observed after following these procedures, do not use the mixture.
 After compatibility testing is complete, dispose of any pesticide wastes in accordance with
the storage and disposal section, Section 9.0, of this label.

1. Public water system means a system for t he provision to the public of piped water for
human consumption if such system has at least 15 service connections or regularly
serves an average of at least 25 individuals daily at least 60 days out of the year.

2. Chemigation systems connect ed to public water systems must contain a functional,
reduced-pressure zone (RPZ), back-flow preventer or the functional equivalent in the
water supply line upstream from the point of pesticide introduction. As an option to the
RPZ, the water from the public water system should be discharged into a reservoir
tank prior to pesticide introduction. There shall be a complete physical break (air gap)
between the flow outlet end of the fill pipe and the top or overflow rim of the reservoir
tank of at least twice the inside diameter of the fill pipe.

3. The pesticide injection pipeline must c ontain a functional, automatic, quick-closing
check valve to prevent the flow of fluid back toward the injection pump.

4. The pesticide injection pipeline must c ontain a functional, normally closed, solenoid-
operated valve located on the intake side of the injection pump and connected to the
system interlock to prevent fluid from being withdrawn from the supply tank, when the
irrigation system is either automatically or manually shut down.

5. The system must contain functional interlo cking controls to automatically shut off the
pesticide injection pump when the water pump motor stops, or in cases where there is
no water pump, when the water pressure decreases to the point where pesticide
distribution is adversely affected.

6. Systems must use a metering pump, such as a positive displacement injection pump
(e.g., diaphragm pump) effectively designed and constructed of materials that are
compatible with pesticides and capable of being fitted with a system interlock.

7. DO NOT apply when wind speed favors drift beyond the area intended for treatment.

4.5.4 Application Directions For Center Pivot Irrigation Equipment

 Determine the amount of Hyetal required to treat the area covered by the irrigation
system.
 Add the required amount of Hyetal into t he same quantity of water used to calibrate the
injection period.
 Operate the system at the same pressure and time interval established during the
calibration.
 Stop injection equipment after treatment is completed. Continue to operate the system
until the Hyetal solution has cleared the last sprinkler head.

4.5.6 Drip (Trickle) Irrigation Instructions
 Hyetal must be applied in a manner that en sures the product is in the root zone.
 Hyetal must be in the root zone to prov ide effective control of target pests.
 Hyetal is most effective when it is applied so that the roots are at or near the site of
application; manage irrigation so that significant quantities of Hyetal remain in the root
zone.
 A pesticide tank is advised for the application of Hyetal in drip chemigation systems.
 Ensure the drip chemigation system is oper ating properly to uniformly distribute the
chemigation application to the crop. Contact the equipment manufacturer, the local
University Extension agent or other experts if you have questions about achieving uniform
distribution of the application. This product must be applied uniformly in the root zone or
poor performance may result. Drip tape or emitters must be located within or directly
adjacent to the root zone.
 In most situations, this product should be ap plied during the middle 1/3 of the irrigation
cycle.
 The minimum injection period is the time that it takes water to move from the injection
point to the furthest emitter in the irrigation zone (propagation time). If this time is not
known, it can be calculated by measuring the time for a soluble dye to move from the

Hyetal
Page 16

injection point to the farthest emitter. A longer injection improves uniformity throughout
the zone, but needs to allow for at least an equal period of water to flush the system and
move the product through the soil.

6.0 RESTRICTIONS AND PRECAUTIONS

6.1 Use Restrictions

 DO NOT apply through any ultra-low volume (ULV) spray system.
 DO NOT apply directly to humans or animals.
 Greenhouse use is prohibited in all crops except for greenhouse tomato production.
 DO NOT use this product in vegetable transplant production.

Hyetal
Page 17

6.1.1 Aerial Application Restrictions
 Use only on crops where aerial applications are indicated.

6.2 Use Precautions
 Avoid application under conditions when un iform coverage cannot be obtained or when
excessive spray drift may occur.

6.3 Spray Drift Management
Mandatory Spray Drift Requirements

Aerial Applications:
 DO NOT release spray at a height greater than 10 ft above the vegetative canopy
unless a greater application height is necessary for pilot safety.
 For all applications, applicat ors are required to use a medium or coarser spray droplet
size (ASABE S572.1).
 The boom length must not exceed 65% of th e wingspan for airplanes or 75% of the
rotor blade diameter for helicopters.
 Applicators must use ½ swath displacement upwind at the downwind edge of the field.
 Nozzles must be oriented so the spray is directed toward the back of the aircraft.
 DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
 DO NOT apply during temperature inversions.

Ground Applications:
 Apply with the nozzle height recommended by the manufacturer, but no more than 3
feet above the ground or crop canopy unless making a pasture or rangeland
application, in which case applicators may apply with a nozzle height no more than 4
feet above the ground.
 For all other applications, applicators are re quired to use a medium or coarser droplet
size (ASABE S572.1).
 DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
 DO NOT apply during temperature inversions.

Boomless Ground Applications:
 Applicators are required to us e a medium or coarser droplet size (ASABE S572.1) for all
applications.
 Setting nozzles at the lowest effective hei ght will help to reduce the potential for spray
drift.
 DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
 DO NOT apply during temperature inversions.

Hyetal
Page 18

6.4 Spray Drift Advisories
 THE APPLICATOR IS RESPONSIBLE FO R AVOIDING OFF-SITE SPRAY DRIFT. BE
AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
 DO NOT apply when conditions favor drift beyond the target area.
 The interaction of many equipment- and weat her-related factors determines the potential
for spray drift.
 DO NOT apply when the wind speed is greater than 10 mph or during periods of
temperature inversions.
 DO NOT apply when weather conditions favor drift from treated areas to non-target
aquatic habitat.

6.4.1 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.

6.4.2 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.

6.4.3 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.

6.4.4 Boom Height – Ground Boom
 Use the lowest boom height that is compat ible with the spray nozzles that will provide
uniform coverage.
 For ground equipment, the boom should remain level with the crop and have minimal
bounce.

6.4.5 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.

Hyetal
Page 19

6.4.6 Shielded Sprayers
 Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded
sprayers.
 Verify that the shields are not interferi ng with the uniform deposition of the spray on the
target area.

6.4.7 Temperature and Humidity
 When making applications in hot and dry conditions, use larger droplets to reduce effects
of evaporation.

6.4.8 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 indica ted 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 duri ng temperature inversions.

6.4.9 Wind
 Drift potential generally in creases 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.

6.4.10 Boomless Ground Applications
 Setting nozzles at the lowest effective height will help to reduce the potential for spray
drift.

6.4.11 Handheld Technology Applications
 Take precautions to minimize spray drift.

6.4.12 Non-Target Areas
 DO NOT apply this pesticide when the product may drift to non-target areas (i.e.
residential areas, bodies of water, known habitat for threatened or endangered species,
non-target crops).

8.0 SEED TREATMENT

 DO NOT use in commercial seed treatment facilities. Use of Hyetal is only permitted on
potato seed, or seed pieces, that is treated and planted within the same agricultural
establishment.
 Hyetal is to be used as an integral part of a potato disease management strategy. This
strategy includes the use of high quality seed and the incorporation of cultural techniques
such as: crop rotation and optimal harvest time for tubers to minimize disease
development, proper handling of tubers to avoid unnecessary bruising, management and
sanitation of equipment and storage areas to reduce inoculum, including avoidance of
storage conditions that lead to free moisture or condensation and application of the seed
piece treatment to clean seed pieces with a properly calibrated application system.
 Apply using standard seed treatment equipment that provides uniform seed coverage.
Uneven or incomplete seed coverage may not give the desired level of disease control.
Add enough water for a slurry volume that will allow for sufficient coverage. Follow the
application instructions provided by the equipment manufacturer for the seed treatment
equipment being used.
 Treatment of highly mechani cally scarred, excessively sprouted, bruised, or damaged
seed or seed pieces, or seed known to be of low vigor, “physiologically old” (that has
multiple sprouts) and poor quality, except for the purpose of curative control of existing
disease pests, may result in reduced germination and/or reduction of seed and seedling
vigor. Treat a small quantity of seed using equipment similar to that planned for treating
the total seed lot. Conduct germination tests on a small portion of seed before committing
the total seed lot to a selected seed treatment. Due to seed quality and seed storage
conditions beyond the control of Syngenta, no claims are made to guarantee the
germination of carry-over seed or propagating material for all crop seed.

8.1 Seed Container Label Requirements
The Federal Seed Act requires that containers containing treated seeds shall be labeled with
the following statements:
 This seed has been treated with mandipropamid fungicide.
 DO NOT use for feed, food, or oil purposes.

In addition, the following statements are required on containers containing potato tuber seed
treated with Hyetal.

 Store away from feeds and foodstuffs.
 DO NOT store Hyetal treated seed in burlap bags or impervious bags/containers or in
areas that are poorly ventilated.
 Wear long-sleeved shirt, long pants and chem ical-resistant gloves when handling treated
seed.
 Treated seeds exposed on the soil surface may be hazardous to wildlife. Cover or collect
treated seeds spilled during loading.
 DO NOT contaminate water bodies when disposing of planting equipment wash- waters.
 DO NOT allow children, pets, or livestock to have access to treated seed.
 Dispose of all excess treated seed. Lefto ver treated seed may be doublesown around the
headland or buried away from water sources in accordance with local requirements. DO
NOT contaminate water bodies when disposing of planting equipment washwaters.
 Treated seed must be planted into the soil at a depth greater than 2 inches.
 DO NOT plant more than 4,500 lb/A of Hyetal-treated potato seed pieces.
 This seed has been treated with mandipropam id at the rate of XXXX mg ai/seed.

required amount of water for
the slurry treater and
dilution rate to be used. A
volume of 2 - 4 fl oz of slurry
mixture/100 lb of potatoes is
advised. Maintain constant
agitation of the slurry during
the seed treatment process.
If necessary, apply dust(s)
following the liquid seed
treatments.

Follow the manufacturer’s
application instructions for
the seed treatment
equipment being used with
appropriate set-up and
calibration. To achieve best
results, the equipment must
be calibrated so that every
potato seed tuber is
uniformly coated with a fine
layer of the slurry mix,
without any excess dripping
out of the treated seed.

If potato seed pieces must
be stored before planting,
consult your local Syngenta
representative for
information on best
management practices for
handling and storing treated
seed potatoes. Some
general guidelines are given
below under Treated Seed
Storage.

Treated Seed Storage
If the treated seed needs to
be stored or held for
(greater than 2 days), then
make sure that the seed is
stored in well-ventilated
areas that would allow air to
move through and out of the
treated seed. An ideal air
temperature is 60 F at a
relative humidity of 85 to 90
percent. Avoid allowing free
moisture to form within or
around the treated seed
during storage.

DIRECTIONS FOR USE

In-Furrow Application
 Apply Hyetal as an in-furrow spray in 5-15 gallons water per acre at planting.
 Mount the spray nozzle so the spray is di rected into the furrow just before the seed
are covered.

Table 1: Soil application rates for Hyetal /1,000 feet of row, based on plant row
spacing

Transplant Water Application
 Transplants should be adequately watered befor e transplanting. Ensure transplant
water volume is sufficient to thoroughly wet the root zone.
 See Table 1 for continuous-stream transplanters. Ensure 4-8 fl oz transplant water/
transplant depending on sandy (4 fl oz) vs silty soil (6-8 fl oz).
 For water-wheel transplanters, use the plant population to determine the rate of
product per plant.

Example:
16 fl oz product x acre = 0.0036 fl oz product
acre 4,356 plants plant

Surface Band or Directed Application
 Apply in a 6- to 12-inch band. See Table 1 for rates.
For ground broadcast application, apply in a minimum of 20 gallons of water per acre,
unless specified otherwise. If rain is not expected within 24 hours after application,
mechanically incorporate (before planting) or sprinkler irrigate (after planting) with 0.25-
0.5 inch of water to move Hyetal into target disease zone.
