GENERAL INFORMATION
Gem® RC Fungicide is a broad spectrum fungicide for the control of certain diseases in potatoes, rice, soybean, and sugar beets. 
Gem® RC Fungicide works by interfering with respiration in plant pathogenic fungi. Gem® RC Fungicide is a potent inhibitor of spore 
germination and mycelial growth.
UNDER CERTAIN CONDITIONS CONDUCIVE TO EXTENDED INFE CTION PERIODS, ADDITIONAL FUNGICIDE APPLICATIONS 
BEYOND THE NUMBER ALLOWED BY THIS LABEL MAY BE NEEDED. UNDER THESE CONDITIONS, USE ANOTHER 
FUNGICIDE REGISTERED FOR THE CROP/DISEASE.

FUNGICIDE RESISTANCE MANAGEMENT 
For resistance management, Gem® RC Fungicide contains a Group 11 fungicide. Any fungal population may contain individuals 
naturally resistant to Gem® RC Fungicide and other Group 11 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: 
x Rotate the use of Gem® RC Fungicide or other Group 11 fungicides within a growing season sequence with different groups 
that control the same pathogens. 
x Use tank mixtures with fungicide 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 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. 
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 Contact your local extension specialist or certified crop advisor for any additional pesticide resistance-management and/or IPM 
recommendations for specific crops and pathogens. 
x For further information or to report suspected resistance contact Bayer CropScience at 1-866-99BAYER (1-866-992-2937). 
You can also contact your pesticide distributor or university extension specialist to report resistance.
IPM: Applications of fungicides should be integrated into an overall disease and pest management program. Cultural practices known 
to reduce disease development should be followed. Consult your local extension specialist, certified crop advisor and/or manufacturer 
representative for additional IPM strategies established for your area. Gem® RC Fungicide may be used in Agricultural Extension 
advisory (disease forecasting or risk assessment) programs that prescribe application timings based on environmental factors favorable 
for disease development.
Product performance: Monitor efficacy of all fungicides used in the disease management program against the targeted pathogen by 
recording factors that may influence fungicide performance and/or disease development. If a fungicide appears to be less effective 
against a pathogen that it previously controlled or suppressed, contact a manufacturer representative, local extension specialist, or 
certified crop advisor for further investigation.
SPRAY EQUIPMENT
Thorough coverage is necessary to provide good disease control. Applications using sufficient water volume to provide thorough and 
uniform coverage generally provide the most effective disease control. For ground application equipment, a minimum of 10 gal./A is 
prescribed. For aerial application equipment, a minimum of 2 gal./A is prescribed for soybeans, and 5 gal./A for other crops.
Not registered for aerial application in New York State.
Broadcast Ground Sprayers
Equip sprayers with nozzles that provide accurate and uniform application. Be certain that nozzles are the same size and uniformly 
spaced across the boom. Calibrate the sprayer before use, and replace worn or damaged nozzles.
Use a pump with the capacity to: (1) maintain a minimum of 35 psi at nozzles, and (2) provide sufficient agitation in the tank to keep the 
mixture in suspension – this requires recirculation of 10% of the tank volume per minute. Use jet agitators or a liquid sparge tube for 
vigorous agitation.
Use screens to protect the pump and to prevent nozzles from clogging. Screens placed on the suction side of the pump should be 16-
mesh or coarser. Do not place a screen in the recirculation line. Use 50-mesh screens at the nozzles. Check nozzle manufacturer’s 
recommendations.
For information on spray equipment and calibration, consult sprayer manufacturer’s and/or state recommendations. For specific local 
directions and spray schedules, consult the current state agricultural experiment station recommendations.
Aerial Application
Avoid application under conditions when uniform coverage cannot be obtained or when excessive spray drift may occur. Do not apply 
directly to humans or animals.
Chemigation: Apply Gem® RC Fungicide through irrigation equipment only to crops and diseases for which the chemigation use is 
specified. Under preventative or light disease pressures the low rate may be applied. Under moderate disease pressures, apply the 
highest rate allowed and use the shorter spray intervals.
DIRECTIONS FOR USE THROUGH SPRINKLER IRRIGATION SYSTEMS
Apply this product only through sprinkler irrigation systems including Hand move, solid set, wheel lines, linear, and center piv ot. Do not 
apply this product through any other type of irrigation system. Illegal pesticide residues in the crop can result from non-unif orm 
distribution of treated water.
For specific information about calibration, contact State Extensio n Service Specialists, equipment manufacturers or other irrig ation 
experts.
SPRAY PREPARATION: Remove scale, pesticide residues, and other foreign matter from the chemical tank and entire injector 
system. Flush with clean water.

5
APPLICATION INSTRUCTIONS: First prepare a suspension of Gem ® RC Fungicide in a mix tank. Fill tank with 1/2 to 3/4 the desired 
amount of water. Start mechanical or hydraulic agitation. Add the required amount of Gem ® RC Fungicide and then the remaining 
volume of water. Start sprinkler and uniformly inject the suspension of Gem® RC Fungicide into the irrigation water line so as to deliver 
the desired rate per acre. The suspension of Gem ® RC Fungicide should be injected with a positive displacement pump into the main 
line ahead of a right angle turn to insure adequate mixing. If you should have any other questions about calibration, you shou ld contact 
State Extension Service specialists, equipment manufacturers or other experts.
NOTE: When treatment with Gem ® RC Fungicide has been completed, further field irrigation over the treated area should be avoided 
for 24 hours to prevent washing the chemical off the crop.
GENERAL PRECAUTIONS FOR APPLICATIONS THROUGH SPRINKLER IRRIGATION SYSTEMS
Maintain continuous agitation in mix tank during mixing and application to assure a uniform suspension. Greater accuracy in calibration 
and distribution will be achieved by injecting a larger volume of a more dilute solution per unit time. The system must contain a 
functional check valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water 
source contamination from backflow. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to 
prevent the flow of fluid back toward the injection pump. The pesticide injection pipeline must also contain 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 shutdown. The system must 
contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops. 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. 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. Do not apply when wind speed favors drift beyond the area intended for 
treatment. If you are unsure of wind conditions which result in drift, contact your local extension agent.
Do not apply when wind speed favors drift, when system connection or fittings leak, when nozzles do not provide uniform distribution or 
when lines containing the product must be dismantled and drained. Crop injury, lack of effectiveness, or illegal pesticide residues in the 
crop may result from non-uniform distribution of treated water.
Allow sufficient time for pesticide to be flushed through all lines and all nozzles before turning off irrigation water. A person 
knowledgeable of the chemigation system and responsible for its operation shall shut the system down and make necessary 
adjustments should the need arise.
Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the 
label-prescribed safety devices for public water supplies are in place.
MIXING PROCEDURES
Prepare no more spray mixture than is needed for the immediate o peration. Thoroughly clean spray equipment before using this 
product. Vigorous agitation is necessary for proper dispersal of the product. Maintain maximum agitation throughout the 
spraying operation. Do not let the spray mixture stand overnight in the spray tank. Flush the spray equipment thoroughly foll owing 
each use and apply the rinsate to a previously treated area.
Gem® RC Fungicide Alone: Add approximately 1/2 of the required amount of water to the mix tank. With the agitator running, add the 
Gem® RC Fungicide to the tank. Continue agitation while adding the rema inder of the water. Begin application of the solution after the 
Gem® RC Fungicide has completely and uniformly dispersed into the mix water. Maintain agitation until all of the mixture has been 
applied.
Gem® RC Fungicide + Tank Mix Partners: Add approximately 1/2 of the required amount of water to the mix tank. Start the agitator 
running before adding any tank-mix partners. In general, tank-mix partners should be added in this order: products packaged in water-
soluble packaging*, wettable powders, wettable granules (dry flowables), liquid flowables such as Gem ® RC Fungicide, liquids, and 
emulsifiable concentrates. Always allow each tank-mix partner to become fully and uniformly dispersed before adding the next p roduct. 
Provide sufficient agitation while adding the remainder of the water. Maintain agitation until all of the mixture has been applied.
*N o t e : When using Gem® RC Fungicide in tank mixtures, all products in water-soluble packaging should be added to the tank before 
any other tank mix partner, including Gem ® RC Fungicide. Allow the water-soluble packaging to completely dissolve and the 
product(s) to completely disperse before adding any other tank-mix partner to the tank.
If using Gem ® RC Fungicide in a tank mixture, observe all directions for us e, crop/sites, use rates, dilution ratios, precautions, and 
limitations which appear on the tank-mix product label. Do not exceed the label ’s dosage rate, and the most restrictive label 
precautions and limitations must be followed. This product must not be mixed with any product which prohibits such mixing. Tan k 
mixtures or other applications of products referenced on this label are permitted only in those states in which the referenced p roducts 
are registered.
Gem® RC Fungicide is compatible with most insecticide, fungicide, and foliar nutrient products. However, the physical compatibility of 
Gem® RC Fungicide with tank-mix partners should be tested before use. To determine the physical compatibility of Gem ® RC 
Fungicide with other products, use a jar test, as described below.
Using a quart jar, add the proportionate amounts of the products to 1 qt. of water. Add wettable powders and water-dispersible granular 
products first, then liquid flowables, and emulsifiable concentrat es last. After thoroughly mixing, let stand for at least 5 m inutes. 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.

6
The crop safety of all potential tank mixes including additives and other pestic ides on all crops has not been tested. Before 
applying any tank mixture not specifically listed on this label, the safety to the target crop must be confirmed. To test for crop 
safety, apply Gem ® RC Fungicide to the target crop in a small area and in accordance with label instructions for the target 
crop.
SPRAY DRIFT MANAGEMENT
Aerial Applications
x For aerial applications, do not apply when wind speeds exceed 15 mph at the application site. If the wind speed is greater 
than 10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 75% or less of the rotor 
diameter for helicopters. Otherwise, the boom length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or 
less of the rotor diameter for helicopters.
x Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater application 
height is necessary for pilot safety.
x Applicators must use ½ swath displacement upwind at the downwind edge of the field.
x Do not apply during temperature inversions.
Airblast applications
x Sprays must be directed into the canopy.
x Do not apply when wind speeds exceed 15 miles per hour at the application site.
x User must tum off outward pointing nozzles at row ends and when spraying outer row.
x Do not apply during temperature inversions
Ground Boom Applications
x Apply with the nozzle height recommended by the manufacturer, but no more than 4 feet above the ground or crop canopy.
x Applicators are required to use a medium or coarser droplet size (ASABE S572).
x Do not apply when wind speeds exceed 15 miles per hour at the application site.
x Do not apply during temperature inversions.
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 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

7
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.
Handheld Technology Applications:
x Take precautions to minimize spray drift.
USE DIRECTIONS FOR SPECIFIC CROPS
Gem® RC Fungicide provides control or suppression of several important diseases of potatoes, rice, soybeans, and sugar beets. When 
reference is made to disease suppression, suppression can mean eith er erratic control from good to fair or consistent control at a level 
below that obtained with the best commercial disease control products.
ROTATIONAL RESTRICTIONS
