PERSONAL PROTECTIVE EQUIPMENT (PPE)
All handlers (mixers, loaders, and applicators, or individuals performing one or more of these tasks)
must wear:
• Long-sleeved shirt and long pants,
• Shoes plus socks, and
• Chemical resistant gloves made of any waterproof material
In addition to the PPE for all handlers, mixer/loaders supporting aerial applications to: corn, cotton,
potatoes, and tuberous and corm vegetables must use closed mixing/loading systems that meet
the requirements listed in the WPS for agricultural pesticides 40 CFR 170.607(d)(2)(i) &(ii) for dermal
protection.
Follow manufacturer’s instructions for cleaning/maintaining PPE. If no such instructions for
washables, use detergent and hot water. Keep and wash PPE separately from other laundry.
ENGINEERING CONTROLS
When handlers use closed systems or enclosed cabs in a manner that meets the requirements listed
in the Worker Protection Standard (WPS) for agricultural pesticides 40 CFR 170.607 (d-f), the handler
PPE requirements may be reduced or modified as specified in the WPS.
Removable chemical extraction probes (also known as “stingers”) used in suction/extraction
systems must be rinsed within the pesticide container prior to removal.
USER SAFETY RECOMMENDATIONS
Users should:
• Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet.
• Remove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean
clothing.
• Remove Personal Protective Equipment immediately after handling this product.
• Wash the outside of gloves before removing.
• As soon as possible, wash thoroughly and change into clean clothing.

ENVIRONMENTAL HAZARDS
This pesticide is toxic to fish and aquatic invertebrates. Do not contaminate surface water through
spray drift. Do not apply directly to water, or to areas where surface water is present or to intertidal
areas below the mean high water mark. Do not contaminate water when cleaning equipment or
disposing of equipment washwater.
Surface Water Advisory
This product may impact surface water quality due to runoff of rain water. This is especially true for
poorly draining soils and soils with shallow ground water. This product is classified as having a high
potential for reaching surface water via runoff for several months or more after application. 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 loading of spiromesifen
from runoff water and sediment. Runoff of this product will be reduced by avoiding applications
when rainfall or irrigation is expected to occur within 48 hours. Sound erosion control practices will
reduce this product’s potential to reach aquatic sediment via runoff.
Groundwater Advisory
Degradates of spiromesifen have properties and characteristics associated with chemicals
detected in groundwater. This chemical may leach into groundwater if used in areas where soils are
permeable, particularly where the water table is shallow.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Read entire label before using this product.
Do not apply this product in a way that will contact workers or other persons, either directly or through
drift. Only protected handlers may be in the same area during application. For any requirements
specific to your State or Tribe, consult the agency responsible for pesticides.

4
AGRICULTURAL USE REQUIREMENTS

• Shoes plus socks
INFORMATION
OBERON ® 4 SC INSECTICIDE/MITICIDE is a Suspension Concentrate formulation. The active
ingredient contained in OBERON 4 SC INSECTICIDE/MITICIDE is active by contact on all mite
development stages. However, mite juvenile stages are often more susceptible than adults. OBERON
4 SC INSECTICIDE/MITICIDE is also highly effective against whitefly nymphs, plus it has a significant
effect on the otherwise difficult to control pupal stage. Make applications to coincide with early
threshold level in developing mite population. OBERON 4 SC INSECTICIDE/MITICIDE can be applied
by air, ground equipment, or through chemigation. However, thorough coverage of all plant parts is
required for optimum performance. Evaluate the performance of OBERON 4 SC 4 – 10 days following
application.

5
RESISTANCE MANAGEMENT
OBERON 4 SC INSECTICIDE/MITICIDE contains an active ingredient with lipid biosynthesis inhibitor
(LBI) mode of action, classified as a Group 23 product. Studies to determine cross-resistance of
Group 23 products with other chemical classes have demonstrated no cross-resistance. Bayer
CropScience strongly encourages that OBERON 4 SC INSECTICIDE/MITICIDE, applied alone or in
tankmix combination with another Group 23 product, be applied in a block rotation or windowed
approach with products from other chemical classes having a different mode of action before using
additional applications of other Group 23 products against the same target pest. Using a block
rotation or windowed approach, along with other IPM practices, is considered an effective use
strategy for preventing or delaying a pest’s ability to develop resistance to a given class of chemistry.
Contact your local extension specialist, certified crop advisor and/or Bayer CropScience
representative for additional resistance management or IPM recommendations. Also, for more
information on Insect Resistance Management (IRM), visit the Insecticide Resistance Action
Committee (IRAC) on the web at http://irac-online.org .
TO DELAY INSECTICIDE RESISTANCE TAKE ONE OR MORE OF THE FOLLOWING STEPS:
•
 R
otate the use of OBERON 4 SC INSECTICIDE/MITICIDE or other Group 23 insecticides/acaricides
within a growing season, or among growing seasons, with different groups that control the
same pests.
•
 U
se tank mixtures with insecticides/acaricides from a different group that are equally effective
on the target pest when such use is permitted. Do not rely on the same mixture repeatedly for
the same pest population. Consider any known cross-resistance issues (for the targeted pests)
between the individual components of a mixture.
o Individual insecticides selected for use in mixtures should be highly effective and be applied
at the rates at which they are individually registered for use against the target species.
o Mixtures with components having the same IRAC mode of action classification are not
recommended for insect resistance management.
o When using mixtures, consider any known cross-resistance issues between the individual
components for the targeted pest(s).

6
o Mixtures become less effective if resistance is already developing to one or both active
ingredients, but they may still provide pest management benefits.
o The insect resistance management benefits of an insecticide mixture are greatest if the two
components have similar periods of residual insecticidal activity. Mixtures of insecticides
with unequal periods of residual insecticide activity may offer an insect resistance
management benefit only for the period where both insecticides are active.
• Adopt an integrated pest management program for insecticide/acaricides use that includes
scouting, uses historical information related to pesticide use, crop rotation, record keeping, and
which considers cultural, biological and other chemical control practices.
• Monitor after application for unexpected target pest survival. If the level of survival suggests
the presence of resistance, consult with your local university specialist or certified pest control
advisor.
• Contact your local extension specialist or certified crop advisors for any additional pesticide
resistance-management and/or IPM recommendations for the specific site and pest problems
in your area.
• For further information or to report suspected resistance, contact Bayer CropScience LP at
1-866-99BAYER (1-866-992-2937). You can also contact your pesticide distributor or university
extension specialist to report resistance.
ENDANGERED SPECIES
The use of any pesticide in a manner that may kill or otherwise harm an endangered species or
adversely modify their habitat is a violation of Federal law.
Following best management practices can help reduce risk to terrestrial pollinators. Examples of
best management practices include checking to confirm hive locations before spraying and applying
pesticides at twilight and at night when pollinators are less likely foraging. For additional resources
on pollinator best management practices, visit https://www.epa.gov/pollinator-protection/
find-best-management-practices-protect-pollinators
Pollinator protection plans are developed by states/tribes to promote communication between
growers, landowners, farmers, beekeepers, pesticide users, and other pest management
professionals to reduce exposure of bees to pesticides. Visit available state/tribal plans for additional
information on how to protect pollinators.

7
How to Report Bee Kills: It is recommended that users contact both the state lead agency and the
U.S. Environmental Protection Agency to report bee kills due to pesticide application. Bee kills can
be reported to EPA at beekill@epa.gov . To contact your state lead agency, see the current listing
of state pesticide regulatory agencies at the National Pesticide Information Center’s website:
http://npic.orst.edu/reg/state_agencies.html
APPLICATION INSTRUCTIONS
For all insects, timing of application should be based on careful scouting and local thresholds.
For low growing berries in Crop Group 13-07G, leafy green vegetables in Crop Group 4A,
fruiting vegetables in Crop Group 8, cucurbits, and leafy brassica greens, applications using
mechanically-pressurized  handguns are prohibited.
Foliar Spray Applications
Foliar applications may be made using properly calibrated ground sprayers, fixed- or rotary-winged
aircraft or through properly designed, sprinkler-type, chemigation equipment (See Chemigation
Systems). Thorough and uniform coverage of plants, with direct contact of the spray mixture to the
target pests, is required for satisfactory control.
Do not apply where thorough coverage of plant is not possible. Applications made with less than
thorough coverage may result in slower activity and/or less overall control from a single application
than an application made with higher gallonages.
Ground applications  must be made in a minimum of 10 gallons/A .
Aerial applications  must be made in a minimum of 5 gallons/A . Aerial applications made to dense
canopies may not provide sufficient coverage of lower leaves to provide pest control. Higher labeled
rates of OBERON 4 SC INSECTICIDE/MITICIDE may be necessary for aerial applications. Do not
apply directly to bodies of water. Time applications to allow sprays to dry prior to rain or sprinkler
irrigations.
Chemigation applications  (See Chemigation Systems ) must be made as concentrated as possible.
For best results apply at 100% input/travel speed, for center pivots or 0.10 inch (2,716 gallons) up
to 0.15 inch (4,073 gallons) of water/A, for other systems. Higher labeled rates of OBERON 4 SC
INSECTICIDE/MITICIDE may be necessary for chemigation applications.

8
Irrigation Timing
If irrigation is used, conduct irrigations efficiently to prevent excessive loss of irrigation waters
through runoff. Time the applications to allow sprays to dry prior to rain or sprinkler irrigations.
Allow at least 48 hours between application of product and any irrigation that results in surface
runoff into lakes, reservoirs, rivers, permanent streams, marshes, potholes, vernal pools, natural
ponds, estuaries, or commercial fish farm ponds.
CHEMIGATION SYSTEMS
OBERON 4 SC INSECTICIDE/MITICIDE may be applied through irrigation systems (chemigation) only
on those crops listed under the crop Application Directions. Do not allow chemigation to run off field.
Types of Irrigation Systems: Apply OBERON 4 SC INSECTICIDE/MITICIDE only through sprinkler,
including center pivot, lateral move, side roll, or overhead solid set irrigation systems. Do not apply
OBERON 4 SC INSECTICIDE/MITICIDE through any other type of irrigation system.
DIRECTIONS FOR ALL APPROVED TYPES OF IRRIGATION SYSTEMS
Uniform Water Distribution and System Calibration:  The irrigation system must provide uniform
distribution of treated water. Crop injury, lack of effectiveness, or illegal pesticide residues in the
crop can result from non-uniform distribution of treated water. The system must be calibrated to
uniformly apply the rates specified. If you have questions about calibration, you should contact State
Extension Service specialists, equipment manufacturers or other experts.
Chemigation Monitoring:  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 and make
necessary adjustments should the need arise.
Drift: Do not apply when wind speed favors drift beyond the area intended for treatment.
Required System Safety Devices: 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.

9
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 shut down. 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 that 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.
Using Water from Public Water Systems: Public water system means a system for the provision
to the public of piped water for human consumption if such system has at least 15 service
connections or regular serves an average of at least 25 individuals daily at least 60 days out of
the year. Chemigation systems connected to public water systems must contain a functional,
reduced-pressure zone, back flow preventer (RPZ) 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. The pesticide
injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow
of fluid back toward the injection. The pesticide injection pipeline must 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 shut down. The system must contain functional
interlocking 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. 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.

10
Cleaning the Chemical Injection System:  In order to accurately apply pesticides, the chemical
injection system must be kept clean; free of chemical or fertilizer residues and sediments. Refer to
your owner’s manual or ask your equipment supplier for the cleaning procedure for your injection
system.
Flushing the Irrigation System:  At the end of the application period, allow time for all lines to flush
the pesticide through all nozzles or emitters before turning off irrigation water. To ensure the lines
are flushed and free of pesticides, a dye indicator may be injected into the lines to mark the end of
the application period.
Equipment Area Contamination Prevention
Plug nozzles that are in the immediate area of control panels, chemical supply tanks, pumps and
system safety devices to prevent chemical contamination of these areas.
Center-Pivot and Automatic-Move Linear Systems:  Inject the specified dosage per acre
continuously for one complete revolution or move of the system. DO NOT USE END GUNS. Run the
system at maximum speed.
Solid Set and Manually Controlled Linear Systems:  Inject during the last 30 to 60 minutes of regular
irrigation period or as a separate 30 to 60 minute application not associated with a regular irrigation.
DO NOT USE END GUNS.

11
MANDATORY SPRAY DRIFT MANAGEMENT
Aerial Applications:
•
 D
o 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.
•
 A
pplicators must select nozzle and pressure that deliver medium or courser droplets
in accordance with American Society of Agricultural & Biological Engineers Standard
641 (ASABE S641). If the windspeed is 10 miles per hour or less, applicators must use ½ swath
displacement upwind at the downwind edge of the field. When the windspeed is between
11-15 miles per hour, applicators must use ¾ swath displacement upwind at the downwind
edge of the field.
•
 D
o not apply when wind speeds exceed 15 mph at the application site. If the windspeed 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.
•
 D
o not apply during temperature inversions.
Ground Boom Applications:
•
 U
ser must only apply with the release height recommended by the manufacturer, but no more
than 4 feet above the ground or crop canopy.
•
 A
pplicators must select nozzle and pressure that deliver medium or courser droplets
in accordance with American Society of Agricultural & Biological Engineers Standard
572 (ASABE S572).
•
 D
o not apply when wind speeds exceed 15 mph at the application site.
•
 D
o 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.

12
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
• 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.
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.
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.

13
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.
WIND
Drift potential generally increases with wind speed. 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.
FOR USE IN CALIFORNIA
Allow growth of a vegetative filter strip within 25 feet (on which the product should not be applied)
along lakes, reservoirs, rivers,
permanent streams, marshes, potholes, vernal pools, natural ponds, estuaries, or commercial fish
farm ponds.
MIXING INSTRUCTIONS
Mix pesticides in areas not prone to runoff such as concrete mixing//loading pads, disked soil in flat
terrain or graveled mix pads, or use a suitable method to contain spills and /or rinsate. Properly empty
and triple-rinse pesticide containers at time of use as stated in the STORAGE AND DISPOSAL section.
Mixing and Loading Requirements
To help prevent potential contamination of groundwater, use of a properly designed and maintained
containment pad for mixing and loading of any pesticide into application equipment. If containment pad
is not used, maintain a minimum distance of 25 feet between mixing and loading area and potential
surface to groundwater conduits such as field sumps, uncased well heads, sink-holes, or field drains.

14
COMPATIBILITY
OBERON 4 SC INSECTICIDE/MITICIDE is physically and biologically compatible with many registered
pesticides and fertilizers or micronutrients. When considering mixing OBERON 4 SC INSECTICIDE/
MITICIDE with other pesticides, or other additives, first contact your supplier for advice. For further
information, contact your local Bayer Representative. If your supplier and Bayer Representative
have no experience with the combination you are considering, conduct a test to determine physical
compatibility. To determine physical compatibility, add the required proportions of each chemical
with the same proportion of water, as will be present in the chemical supply tank, into a suitable
container, mix thoroughly and allow to stand for five minutes. If the combination remains mixed, or
can be readily re-mixed, the mixture is considered physically compatible.
ORDER-OF-MIXING
OBERON 4 SC INSECTICIDE/MITICIDE may be used with other recommended pesticides, fertilizers
and micronutrients. The proper mixing procedure for OBERON 4 SC INSECTICIDE/MITICIDE alone or
in tank mix combinations with other pesticides is:
1) Fill the spray tank 1/4 to 1/3 full with clean water;
2) While recirculating and with the agitator running, add any products in PVA bags (See Note) . Allow
time for thorough mixing;
3) Continue to fill spray tank with water until 1/2 full;
4) Add any other wettable powder (WP) or wettable granules (WG) products;
5) Add the required amount of OBERON 4 SC INSECTICIDE/MITICIDE, and any other “flowable” (FL or
SC) type products;
6) Allow enough time for thorough mixing of each product added to tank;
7) If applicable, add any remaining tank mix components: emulsifiable concentrates (EC), fertilizers
and micronutrients.
8) Fill spray tank to desired level and maintain constant agitation to ensure uniformity of spray
mixture.
NOTE: Do not use PVA packets in a tank mix with products that contain boron or release free chlorine.
The resultant reaction of PVA and boron or free chlorine is a plastic that is not soluble in water or
solvents.
