Environmental Hazards
Do not apply directly to water, to areas where surface water is present, or to intertidal
areas below the mean high water mark. Do not contaminate water when disposing of
equipment washwater or rinsate.
This product may contaminate water through drift of spray in wind. This product has a
potential for runoff for several months or more after application. Poorly draining soils
and soils with shallow water tables are more prone to produce runoff that contains this
product. A level, well maintained vegetative buffer strip between areas to which this
product is applied and surface water features such as ponds, streams, and springs will
reduce the potential for contamination of water from rainfall-runoff. Runoff of this
product will be reduced by avoiding applications when rainfall is forecasted to occur
within 48 hours.
Do not discharge effluent containing this product into lakes, streams, ponds, estuaries,
oceans, or other waters unless in accordance with the requirements of a National
Pollutant Discharge Elimination System (NPDES) permit and the permitting authority
has been notified in writing prior to discharge. Do not discharge effluent containing this
product to sewer systems without previously notifying the local sewage treatment plant
authority. For guidance, contact your State Water Board or regional office of the EPA.

USE INFORMATION
Apply Micora as a foliar protectant fungicide for control of diseases caused by downy
mildews and Phytophthora spp. Micora can also be applied as a drench for control of
root and stem diseases caused by Phytophthora spp. Apply Micora prior to disease
development, rotating with other effective fungicides having a different mode of action.
Application: Mix only the amount of spray solution needed for immediate application.
Thorough coverage is necessary to provide good foliar disease control. Make foliar
applications in an adequate water volume to achieve thorough and uniform coverage
without excessive runoff (to drip).
Adjuvants: For some uses on this label, a spreading/penetrating type adjuvant such as
a non-ionic surfactant, crop oil concentrate, silicone based, or blend may be added at
the manufacturer’s recommended rates to improve coverage on waxy or hard to wet
plant surfaces. When an adjuvant is to be used with this product, the use of an adjuvant
that meets the standards of the Chemical Producers and Distributors Association
(CPDA) adjuvant certification program is recommended.
Efficacy: Under certain conditions conducive to extended infection periods, use
another registered fungicide for additional applications if maximum amount of Micora
has been used. If isolates that are resistant to Group 40 fungicides are present, efficacy
may be reduced for certain diseases. The higher rates in the rate range and/or shorter
spray intervals may be required under conditions of heavy infection pressure, highly
susceptible varieties, or when environmental conditions conducive to disease exist.
Integrated Pest Management (IPM): Micora should be integrated into an overall
disease and pest management strategy whenever the use of a fungicide is required.
Cultural practices known to reduce disease development should be followed. Consult
your local agricultural authorities for additional IPM strategies established for your area.
Micora may be used in State Agricultural Extension advisory (disease forecasting)
programs which recommend application timing based on environmental factors
favorable for disease development.
Resistance Management
MANDIPROPAMID GROUP
40 FUNGICIDE
For resistance management, please note that Micora contains a Group 40
fungicide. Any fungal population may contain individuals naturally resistant to Micora
and other Group 40 fungicides. A gradual or total loss of pest control may occur over
time if these fungicides are used repeatedly on the same plants. Appropriate resistance-
management strategies should be followed.
To delay fungicide resistance, take one or more of the following steps:
Micora
Page 7
x Rotate the use of Micora or other Group 40 fungicides within a growing season
sequence with different groups that control the same pathogens.
x Use tank mixtures with fungicides from a different 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.
x Adopt an integrated disease management program for fungicide use that includes
scouting, uses historical information related to pesticide use, 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.
x 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.
x Monitor treated fungal populations for resistance development.
x Contact your local Syngenta representative, retailer, or extension specialist for any
additional pesticide resistance-management and/or IPM recommendations for
specific plants and pathogens
x 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:
x Apply a maximum of 4 foliar sprays or 2 drench applications during one crop cycle
unless otherwise stated in the specific use directions.
x Apply no more than 2 sequential applications unless otherwise stated in the specific
use directions.
x Use Micora in rotation or in tank mix with an effective fungicide with a different mode
of action – one that provides satisfactory disease control when used alone at the
mixture rate.
Syngenta encourages responsible product stewardship to ensure effective long-term
control of the weed species on this label.
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
x Volume - Increasing the spray volume so that larger droplets are produced will
Micora
Page 8
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.
x Pressure - Use the lowest spray pressure recommended for the nozzle to
produce the target spray volume and droplet size.
x Spray Nozzle - Use a spray nozzle that is designed for the intended application.
Consider using nozzles designed to reduce drift.
Controlling Droplet Size – Aircraft
x 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.
BOOM HEIGHT – Ground Boom
For ground equipment, the boom should remain level with the crop and have minimal
bounce.
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.
Boomless Ground Applications:

Setting nozzles at the lowest effective height will help to reduce the potential for spray
drift.
Handheld Technology Applications
Take precautions to minimize spray drift.
MIXING INSTRUCTIONS
Mixing Instructions
x Prepare no more spray mixture than is required for the immediate operation.
x Thoroughly clean spray equipment before using this product.
x Agitate the spray solution before and during application.
x Rinse spray tank thoroughly with clean water after each day’s use and dispose of
pesticide rinsate by application to an already treated area.
x Do not allow spray mixture to stand overnight or for prolonged periods of time (more
than 3 hours) without agitation.
Micora Alone (no tank mix):
x Add ½- Ҁ of the required amount of water to the spray or mixing tank.
x With the agitator running, add Micora to the tank.
x Continue agitation while adding the remainder of the water.
x Begin application of the spray solution after Micora has completely dispersed into
the mix water.
x Maintain agitation until all of the mixture has been sprayed.
Micora + Tank Mixtures: Micora is usually compatible with all tank-mix partners. To
determine the physical compatibility of Micora with other products, use a jar test. Using
a quart jar, add the proportionate amounts of the products to 1 quart of water. Add
wettable powders and water dispersible granular products first, then liquid flowables,
and emulsifiable concentrates last. After thoroughly mixing, let stand for at least 5
minutes. If the combination remains mixed or can be remixed readily, it is physically
compatible. Once compatibility has been proven, use the same procedure for adding
required ingredients to the spray tank.
It is important to mix only the amount of product that can be sprayed
immediately. Continuous agitation is recommended. If circumstances cause a
delay of more than 3 hours, the product(s) may settle and be difficult to
re-suspend. If this occurs, good agitation is required for a minimum of 15
minutes before and during spray operation.
Mixing in the Spray Tank
x Add ½- Ҁ of the required amount of water to the spray or mixing tank.
x With the agitator running, add the tank mix partner(s) into the tank in the same order
as described above.
Micora
Page 10
x Allow the material to completely dissolve an d disperse into the mix water. Continue
agitation while adding the remainder of the water and Micora to the spray tank.
x Allow Micora to completely disperse.
x Spray the mixture with the agitator running.
APPLICATION EQUIPMENT
Micora may be applied with application equipment commonly used for greenhouse and
nursery crop production. Proper adjustments and calibration of spraying equipment to
give good canopy penetration and coverage is essential for good disease control.
Aerial Application: Micora may be applied by air to field-grown roses only.
Spray Equipment
Nozzles
x Add ½- Ҁ of the required amount of water to the spray or mixing tank.
x It is suggested that screens be used to protect the pump and to prevent nozzles
from clogging.
x Screens placed on suction side of pump should be 16-mesh or coarser.
x Do not place a screen in the recirculation line.
x Use 50-mesh or coarser screens between the pump and boom, and where required,
at the nozzles.
x Check nozzle manufacturer’s recommendations.
Pump
x Use a pump with capacity to:
(1) maintain 35-40 psi at nozzles
(2) provide sufficient agitation in tank to keep mixture in suspension - this
requires recirculation of 10% of tank volume per minute.
x Use a jet agitator or liquid sparge tube for agitation.
x Do not air sparge.
For more information on spray equipment and calibration, consult sprayer
manufacturers’ and state recommendations. For specific local directions and spray
schedules, consult the current state agricultural recommendations.
Application Through Irrigation Systems (Chemigation)
x Apply this product only th rough overhead, hand held, micro-irrigation systems (e.g.,
drip, trickle, spaghetti tubes and micro sprinklers) and motorized calibrated irrigation
systems. Do not apply this product through any other type of irrigation system.
x Plant injury and/or poor disease control can result from non-uniform distribution of
treated water.
Micora
Page 11
x If you have questions about calibration, you should contact State Extension Service
specialists, equipment manufacturers, or other experts.
x Do not connect an irrigation system (including greenhouse systems) used for
pesticide application to a public water system, unless the pesticide label-prescribed
safety devices for public water systems are in place.
x A person knowledgeable of the chemigation system and responsible for its
operation, or under the supervision of the responsible person, shall shut the system

down.
4. The system must contain functional interl ocking controls to automatically shut off
the pesticide injection pump when the water pump motor stops.
5. The irrigation line or water pump must include a functional pressure switch which
will stop the water pump motor 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.
Motorized Calibrated Irrigation Equipment
x Determine the acreage covered by the sprinklers.
x Fill injector solution tank with water and adjust flow rate to use the contents over a
20- to 30-minute interval. When applying Micora through irrigation equipment, use
the lowest obtainable water volume while maintaining uniform distribution.
Micora
Page 12
x Determine the amount of Micora required to treat the area covered by the irrigation
system.
x Add the required amount of Micora into the same quantity of water used to calibrate
the injection period.
x Operate the system at the same pressure and time interval established during the
calibration.
x Stop injection equipment after treatment is completed. Continue to operate the

another effective non-Group 40
fungicide.
Plant Safety: Micora has been shown to be safe when applied at the recommended
rates to the ornamental plants listed in Table 2. However, due to the large number of
genera, species and varieties of ornamental and nursery plants, it is impossible to test
every one for tolerance to Micora. Neither the manufacturer nor the seller has
determined whether Micora can be used safely on genera, species, or varieties of
ornamental and nursery plants not specified on this label. The user should conduct
small scale testing at the recommended rates to ensure plant safety prior to broad scale
commercial use on plant genera and species not listed in this label.
When using an adjuvant or tank mix partner, the user should conduct small scale testing
at the recommended rates to ensure plant safety prior to broad scale commercial use.
