 Case Number: 669126 
 
Dear Kristi Barnett: 
 
The amended label referred to above, submitted in connection with registration under the 
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, is acceptable. 
However, EPA reviewed only the label changes highlighted, marked, or otherwise indicated on 
the submitted label. Any other changes to the previously approved label that were not clearly 
highlighted, marked, or otherwise indicated in your submission were not reviewed and may 
form the basis of regulatory and/or enforcement action if later discovered by the Agency. 
Further, submission of a label amendment application with unidentified changes may be 
considered a knowing submission of false information to the Agency. This approval does not 
affect any conditions that were previously imposed on this registration. You continue to be 
subject to existing conditions on your registration and any deadlines connected with them. 
 
The highlighted label submitted with the application has been stamped “Accepted Only 
Indicated Revisions Reviewed” and is enclosed for your records. 
 
This labeling supersedes all previously accepted labeling. You must submit one copy of the final 
printed labeling before you release the product for shipment with the new labeling. In 
accordance with 40 CFR § 152.130(c), you may distribute or sell this product under the

Page 2 of 2 
EPA Reg. No. 279-9596 
Case Number 669126 
 
previously approved labeling for 18 months from the date of this letter. After 18 months, you 
may only distribute or sell this product if it bears this new revised labeling or subsequently 
approved labeling. “To distribute or sell” is defined under FIFRA section 2(gg) and its 
implementing regulation at 40 CFR § 152.3. 
 
Should you wish to add/retain a reference to the company’s website on your label, then please 
be aware that the website becomes labeling under FIFRA and is subject to review by the 
Agency. If the website contains any false or misleading statement, design, or graphic, the 
product may be misbranded and unlawful to sell or distribute under FIFRA Sections 2(q)(1)(A) 
and 12(a)(1)(E). 40 CFR § 156.10(a)(5) lists examples of statements EPA may consider false or 
misleading. In addition, regardless of whether a website is referenced on the product label, 
claims made as part of the product’s sale or distribution may not substantially differ from those 
claims approved through the registration process under FIFRA Section 12(a)(1)(B). Therefore, 
should the Agency find or if it is brought to our attention that a website contains false or 
misleading statements or claims substantially differing from the EPA approved registration, the 
product will be referred to the EPA’s Office of Enforcement and Compliance Assurance. 
 
Your release for shipment of the product constitutes acceptance of these conditions. If these 
conditions are not complied with, the registration will be subject to cancellation in accordance 
with FIFRA section 6.

PRODUCT INFORMATION 
STEWARD® EC insecticide is an emulsifiable concentrate that can be applied as a foliar spray to control many 
important insects. STEWARD® EC insecticide is diluted with water for application. Always shake well before use. Do 
not formulate this product into any other end-use products without written permission of FMC. 
USE RESTRICTIONS 
• Do not use in greenhouses. 
• Not for use on ornamental plants or plants being grown for ornamental purposes. 
• Not for use in residential areas. 
• FOR FOLIAR APPLICATIONS OF THIS PRODUCT TO A CROP WHERE BEES ARE UNDER CONTRACT TO 
POLLINATE THAT CROP: Foliar application of this product is prohibited to a crop from onset of flowering until flowering is 
complete when bees are under contract for pollination services to that crop unless: 
• the application is being made in the time period between 2-hours prior to sunset until sunrise; OR, 
• the application is being made at a time when the temperature at the application site is 50 oF or less. 
 
 
Follow manufacturer's instructions for cleaning/maintaining personal protective equipment (PPE). If no such instructions for 
washables exist, use detergent and hot water. Keep and wash PPE separately from other laundry. When handlers use closed 
systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the Worker Protection Standard 
(WPS) for agricultural pesticides (40 CFR 170.240(d)(4-6), the handler PPE requirements may be reduced or modified as 
specified in the WPS. IMPORTANT: when reduced PPE is worn because a closed system is being used, handlers must be 
provided all PPE specified above for “applicator and other handlers” and have such PPE immediately available for use in an 
emergency, such as a spill or equipment breakdown. 
 
 
 
 
ENVIRONMENTAL HAZARDS 
This pesticide is toxic to mammals, birds, fish and aquatic invertebrates. 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 disposing 
of equipment washwater or rinsate. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated 
areas. Runoff of this product will be reduced by avoiding application when rainfall is forecasted to occur within 24 hours. 
Rinsing application equipment over the treated area will help avoid runoff to water bodies or drainage systems. Do not 
apply to any impervious surfaces which may contact or lead directly to surface water, storm drains, or urban runoff 
conveyance systems (gutters). This product is highly toxic to bees and other pollinating insects exposed to direct 
treatment or to residues in/on blooming crops or weeds. Protect pollinating insects by following label directions intended 
to minimize drift and reduce pesticide risk to these organisms. 
2 
AGRICULTURAL USE REQUIREMENTS 
STEWARD® EC insecticide must be used only in accordance with its labeling and with the Worker Protection Standard, 40 
CFR part 170. This Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, 
and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, 
notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on 
this label about personal protective equipment (PPE) and restricted-entry interval. The requirements in this box only apply 
to uses of this product that are covered by the Worker Protection Standard. 
Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 12 hours. 
For early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything 
that has been treated, such as plants, soil, or water, wear: 
Coveralls over long-sleeved shirt and long pants 
Socks plus chemical resistant footwear 
Chemical-resistant gloves made of Butyl Rubber ≥14 mils, Natural rubber ≥14 mils, Neoprene Rubber ≥14 mils, or 
Nitrile Rubber ≥14 mils.

For fields to which applications of STEWARD® EC insecticide will be made, construct a vegetative filter strip if one does not 
already exist. Existing and new filter strips must be, at a minimum, 10-foot-wide and composed of grass or other permanent 
vegetation between the field edge and down gradient aquatic habitat (such as, but not limited to, lakes; reservoirs; rivers; 
permanent streams; marshes or natural ponds; estuaries; and commercial fish farm ponds). Vegetative filter strips must be 
maintained to optimize their utility. Only apply products containing indoxacarb onto fields where a maintained vegetative 
buffer strip of at least 10 feet exists between the field and down gradient aquatic habitat. 
CHEMIGATION: Do not apply this product through any type of irrigation system except for application to alfalfa, field corn 
subgroup15-22C, cottonseed subgroup 20C, peanut, potato and soybean, and as allowed by Federal Supplemental and 
Special Local Need (SLN) labeling. (See “Application By Chemigation” section of the label.) 
 
INTEGRATED PEST MANAGEMENT 
FMC supports the use of Integrated Pest Management (IPM) programs to control pests. This product may be used as part 
of an IPM program which can include biological, cultural, and genetic practices aimed at preventing economic pest 
damage. IPM principles and practices include field scouting or other pest detection methods, correct target pest 
identification, population monitoring, rotation of insecticides with different modes- of-action, and treating when target pest 
populations reach locally determined action thresholds. Consult your state cooperative extension service, professional 
consultants, product manufacturer or other qualified authorities to determine appropriate action treatment threshold levels 
for treating specific pest/crop or site systems in your area. 
 
SCOUTING 
Monitor insect populations to determine whether or not there is a need for application of STEWARD® EC insecticide based 
on label recommendations and locally determined economic thresholds. More than one treatment of STEWARD® EC 
insecticide may be required to control a population of pests. 
 
INSECT RESISTANCE MANAGEMENT 
For resistance management, STEWARD® EC insecticide contains the active ingredient indoxacarb which is a Mode of Action 
Group 22A insecticide. Insecticides with the same group number affect the same biological site of action on the target pest and 
when used repeatedly in the same treatment area, naturally-occurring resistant individuals may survive correctly applied 
insecticide treatments, reproduce, and become dominant. 
 
To delay the development of insecticide resistance, a resistance management strategy should include incorporation of cultural 
and biological control practices, alternation to different mode of action insecticides on succeeding generations, targeting the 
most susceptible life stage, and where possible controlling multiple life stages of the same pest. 
 
Consult with your local or state agricultural authorities or product manufacturer, or visit the Insecticide Resistance Action 
Committee (IRAC) on the web at http://www.irac-online.org for more information about developing a resistance management 
strategy. 
 
Unless directed otherwise in the specific crop/pest sections of this label, follow these guidelines to delay the development of 
insecticide resistance: 
• Apply STEWARD® EC insecticide and other Group 22 insecticides within a single “treatment widow” to minimize 
exposing successive generations of a pest species to the same mode of action insecticides. 
• A “treatment window” is defined as the period of residual insecticidal activity provided by one or more applications of 
products with the same mode of action not to exceed approximately 30 days. 
• Within the Group 22 “treatment window”, make no more than 2 applications of STEWARD® EC insecticide or other 
Group 22 insecticides. 
• Following a Group 22 “treatment window”, rotate to a “treatment window” of effective insecticides with a different 
mode of Action Group Number. The period between Group 22 “treatment windows” should be at least 30 days. 
• For short cycle crops (< 50 days), the duration of the crop cycle may be considered as the Group 22 “treatment 
window” if no Group 22 insecticides are used during the next crop cycle at the same farm location. 
• If STEWARD® EC insecticide is tank mixed with other insecticides, then apply rates that are individually registered for 
use against the target species. Do not rely on the same mixture repeatedly to control the same pest species and follow the 
same “treatment window” rotation recommendation described above for the tank-mixed products. 
• Use labeled rates of STEWARD® EC insecticide when applied alone or in tank mixtures. 
• Monitor after application for unexpected target pest survival. If insect resistance is suspected consult with your 
manufacturer’s representative, local university specialist, or certified pest control advisor. 
 
If resistance to STEWARD® EC insecticide develops in your area other products with a similar mode of action (Mode of 
Action Group 22) may not provide adequate control.

ADVISORY BEST MANAGEMENT PRACTICES FOR POLLINATOR PROTECTION 
 The following best management practices (BMPs) can help reduce risk to pollinators: 
• Develop and maintain clear communication with local beekeepers to help protect honey bees. To the extent possible, 
advise beekeepers within a 1-mile radius 48-hrs in advance of the application, and confirm hive locations before spraying. 
• Avoiding applications during bloom. 
• Avoiding applications when bees are actively foraging. 
• Applying pesticides in the evening or early morning hours when fewer bees are foraging. 
• Using Pollinator Protection Plans when they are available. These plans may be available from state lead agencies and 
promote communication between growers, landowners, farmers, beekeepers, pesticide users, and other pest management 
professionals to reduce exposure of bees and other pollinators to pesticides. 
• For additional resources on pollinator BMPs and Pollinator Protection Plans, visit https://www.epa.gov/pollinator-
protection/find-best-management-practices-protectpollinators 
 
BENEFICIAL ARTHROPODS 
Other than reducing the target pest species as a food source, STEWARD® EC insecticide helps conserve certain beneficial 
arthropods, including parasitic wasps, predatory mites, big-eyed bugs, damsel bugs, minute pirate bugs, and spiders. While these 
beneficials cannot be relied upon to control pests, they are of potential value and can be monitored along with pests in pest 
management programs on these crops. 
 
APPLICATION 
Apply at the listed rates when insect populations reach locally determined economic thresholds. Consult the cooperative 
extension service, professional consultants or other qualified authorities to determine appropriate threshold levels for treatment 
in your area. 
STEWARD® EC insecticide applications should target eggs and small instar larvae. 
Follow-up treatments of STEWARD® EC insecticide should be applied, as needed, to keep pest populations within threshold 
limits. Apply STEWARD® EC insecticide at 5 to 7 day intervals or as needed to manage specific target insect pests, as 
specified in the specific crop sections, to maintain control. 
Use sufficient water to obtain thorough, uniform coverage. 
Because STEWARD® EC insecticide is most effective through ingestion of treated plant material, thorough spray coverage is 
essential for optimum control of targeted pest insects. Using increased water volumes will typically result in better spray 
coverage, especially under adverse conditions such as dry, hot weather or dense plant foliage. STEWARD® EC insecticide 
may be applied by ground, aerial or overhead sprinkler chemigation application equipment. For aerial application use the 
following directions unless otherwise specified in specific crop/pest sections of this label or EPA-approved supplemental 
labeling: use a minimum of 3 gal water per acre (gpa) [minimum of 5 gal water per acre in Arizona and California]. For ground 
application use the following directions unless otherwise specified in specific crop/pest sections of this label or EPA-approved 
supplemental labeling: use a minimum of 5 gal. water per acre. Higher gallonage will provide better coverage and performance. 
For overhead chemigation applications, see "Application by Chemigation" section of the label for guidance on water volumes 
to be used. 
Use of Adjuvants: In some s ituations where coverage is difficult to achieve such as closed canopy, dense foliage, plants with 
waxy leaf surfaces, or less than optimum application equipment, an adjuvant may improve performance. Use only adjuvant 
products that are labeled for agricultural use and follow the directions on the manufacturer's label. 
 
SPRAY PREPARATION 
Spray equipment must be clean and free of previous pesticide deposits before applying STEWARD® EC insecticide. Fill 
spray tank 1/4 to 1/2 full of water. Add STEWARD® EC insecticide directly to spray tank. Mix thoroughly to fully 
disperse the insecticide; once dispersed continued agitation is required. Use mechanical or hydraulic means; do not use air 
agitation. Spray mix must not be stored overnight in spray tank. Observe the most restrictive of the labeling limitations and 
precautions of all products used in mixtures.

Tank Mixing and Compatibility - Since formulations may be changed and new ones introduced, it is a best practice that 
users premix a small quantity of a desired tank mix and observe for possible physical incompatibility (settling out, 
flocculation, crystallization, etc.). It is the pesticide user's responsibility to ensure that all products are registered for the 
intended use. This product can be tank mixed with pesticide products labeled for use on crops on this label in accordance 
with the most restrictive of label limitations and precautions. Do not exceed label application rates. This 
product cannot be mixed with any product containing a label prohibition against such mixing. 
Spray volumes of less than 3 gal of water and tank mixtures of more than two products can increase the chances of 
incompatible spray mixtures. A jar test (as described below) should be conducted when label guidance is not given or prior 
experience with a specific tank mixture is unknown. The jar test should follow the mixing sequence below in water volume 
proportional to the planned spray tank water volume to assure that the tank mixture is compatible. Constant agitation may 
be needed during mixing and spraying of mixtures. STEWARD® EC insecticide is compatible with most commonly used 
plant protectants. 
Steps to conduct a jar test to determine physical tank mix compatibility of STEWARD® EC insecticide with other products: 
- Add clean water to the jar in proportion to the planned water volume that will be used in the spray tank (a jar size of 16 
oz is acceptable). 
- While wearing the most restrictive PPE, mix proper proportional amounts of STEWARD® EC insecticide and desired 
tank mix partner(s) as will be present in the spray tank. Add one product at a time following the sequence of addition 
according to formulation type provided in this label. 
- Seal and shake mixture after each product is added. 
- Allow to stand for 1 hour. 
- View jar to determine if settling, flocculation, crystallization or any other undesirable changes have happened. 
- If none of the above is observed or the solution can be easily remixed after shaking, the mixture is compatible with 
STEWARD® EC insecticide. 
- If the tank mixture is not compatible, a higher water volume, reduced rate of the tank mix partner(s), reduced number of 
tank mix partners or a compatibility agent may be needed. 
 
Tank Mixtures and Crop Safety 
Crop varieties can differ in their responsiveness to tank mixtures, and environmental conditions can influence product 
performance and crop response. It is not possible to test STEWARD® EC insecticide alone or with all possible tank mix 
combinations on all varieties under all environmental conditions. When considering the use of a tank mixture on a labeled crop 
without prior experience, or which is not specifically described on STEWARD® EC insecticide product labeling or in other 
FMC product use instruction, it is important to check crop safety first. To test for crop safety prepare a small volume of the 
intended tank mixture, apply it to an area of the target crop as directed by both this and the tank mix partner product labels, and 
observe the treated crop to ensure that a phytotoxic response does not occur. 
Use of STEWARD® EC insecticide in any tank mixture applications that is not specifically described on STEWARD® EC 
insecticide product labeling or in other FMC product use instructions, could potentially result in crop injury. Follow the 
precautions on this label and on the label for any other product to be used in tank mixtures before making such applications to 
your crops. It is the pesticide user's responsibility to ensure that all products are registered for the intended use. Read and follow 
the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow 
the most restrictive directions for use and precautionary statements of each product in the tank mixture .

SPRAY TANK CLEANOUT 
Prior to application, start with clean, well maintained application equipment. Immediately following application, 
thoroughly clean all spray equipment to reduce the risk of forming hardened deposits which might become difficult to 
remove. 
Drain spray equipment. Thoroughly rinse sprayer and flush hoses, boom and nozzles with clean water. 
Clean all other associated application equipment. Take all necessary safety precautions when cleaning equipment. Do not 
clean near wells, water sources or desirable vegetation. Dispose of waste rinse water in accordance with local regulations. 
 
APPLICATION BY CHEMIGATION –ALFALFA (GROWN FOR SEED), FIELD CORN 
SUBGROUP 15-22C, COTTON, PEANUT, POTATO AND SOYBEAN (HULLS AND 
SEED) 
 
Instructions for the Use of STEWARD® EC insecticide in Overhead Sprinkler Chemigation Systems. 
Overhead chemigation applications offer the advantage of greater penetration and coverage of the target plant. However, 
typical chemigation applications are more dilute than ground or aerial applications. For best results, it is recommended to 
keep the concentration of STEWARD® EC insecticide as high as possible in the application. Apply STEWARD® EC 
insecticide in 0.1 to 0.2 inches of water per acre. STEWARD® EC insecticide is most active as an ingestion insecticide, 
although it does have activity as a direct contact insecticide. For best results, applications of STEWARD® EC insecticide 
should ensure thorough coverage of the target plant to maximize the opportunity for target insects to ingest STEWARD® 
EC insecticide. 
 
Types of Chemigation Systems: 
STEWARD® EC insecticide may be applied only through overhead sprinkler irrigation systems. Overhead irrigation 
systems include the following; center pivot, end tow, hand move, lateral move, side roll, solid set and wheel line. Center 
pivot and lateral move irrigation systems are preferred. Other overhead sprinkler systems may be used if they provide 
uniform water distribution. Do not apply STEWARD® EC insecticide through any other type of irrigation system. Do not 
use filter screens smaller than 50 mesh throughout the system, due to possible build up of material on 100 mesh or smaller 
screens. 
 
Directions for Chemigation: 
Preparation 
A pesticide tank is recommended for the application of STEWARD® EC insecticide in chemigation systems. Thoroughly 
clean the injection system and tank of any fertilizer or chemical residues using a standard clean -out procedure. Dispose of 
any residues in accordance with State and Federal laws. With the mix tank 1/4 to 1/2 full with water and the agitator 
running, measure the required amount of STEWARD® EC insecticide and add it to the tank. Then add additional water to 
bring your total pesticide mixture up to the desired volume for your application. Note: Always add the STEWARD® EC 
insecticide to water, never put STEWARD® EC insecticide into a dry tank or other mixing equipment without first adding 
water. See "Tank Mixing Sequence" section of the container label for tank mixing sequence. Continue to agitate the 
mixture throughout the application process. Use mechanical or hydraulic agitation, do not use air agitation. Highly alkaline 
water should be buffered so that the pH of the spray solution is in the range of neutral to slightly acidic. 
 
Injection Into Chemigation Systems 
Inject the proper amount of STEWARD® EC insecticide into the irrigation water flow using a positive displacement 
injection pump. Injection should occur at a point in the main irrigation water flow to ensure thorough mixing with the 
irrigation water. For continuously moving systems, inject the solution containing STEWARD® EC insecticide into the 
irrigation water line continually and uniformly throughout the irrigation cycle. Apply in no more than 0.2 inches of water 
per acre. For overhead sprinkler systems that are stationary, add the solution containing STEWARD® EC insecticide to the 
irrigation water line and apply no more than 0.2 inches of water per acre just before the end of the irrigation cycle. 
 
Uniform Water Distribution 
The irrigation system used for application of STEWARD® EC insecticide must provide for uniform distribution of 
STEWARD® EC insecticide treated water. Non-uniform distribution might result in crop injury, lack of effectiveness or 
illegal pesticide residues in or on the crop being treated. Ensure the irrigation system is calibrated to uniformly distribut e 
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. 
6

Equipment Calibration 
Calibrate the irrigation system and injector before applying STEWARD® EC insecticide. Calibrate the injection pump 
while the system is running using the expected irrigation rate. If you have questions about calibration, you should contact 
your state extension service specialists, equipment manufacturer or other experts. 
 
Monitoring of Chemigation Applications 
A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of a 
responsible person, shall shut the system down and make necessary adjustments should the need arise. Wear the personal 
protective equipment as defined in the PPE section of the label for applicators and other handlers when making adjustments 
or repairs on the chemigation system when STEWARD® EC insecticide is in the irrigation water. 
 
Required System Safety Devices 
Do not connect any irrigation system used for pesticide applications to a public water system unless the pesticide label - 
prescribed safety devices are in place. Public water system means a system for the provision to the public of piped water for 
human consumption, if such a system has at least 15 service connections or regularly serves an average of at least 25 
individuals at least 60 days out of the year. 
1. 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. 
2. The pesticide injection pipeline must contain a functional, automatic, quick -closing check valve to prevent the flow of 
fluid back toward the injection pump. 
3. 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. 
4. The system must contain functional interlocking 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. Chemigation systems connected to public water systems must contain a functional, reduced- pressure zone, backflow 
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 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. 
 
Operation 
Start the water pump and sprinkler, and let the system achieve the desired pressure and speed before starting the injector. 
Start the injector and calibrate the injection system according to the directions above. This procedure is necessary to deliv er 
the desired rate per acre in a uniform manner. When the application is finished, allow the entire irrigation and injector 
system to be thoroughly flushed clean before stopping the system. 
• End guns must be turned off during the application, if they irrigate nontarget areas or if they do not provide uniform 
application and coverage. 
• Plug nozzles in the immediate area of control panels, chemical supply tanks and system safety devices to prevent 
contamination of these areas. 
• Do not apply when wind speed favors drift beyond the area intended for treatment. 
• Do not apply when system connections or fittings leak or when nozzles do not provide uniform distribution. 
• Do not allow irrigation water to collect or run-off during chemigation. 
 
Cleaning the System 
Thoroughly clean the injection system and tank of any fertilizer or chemical residues using a standard clean- out procedure. 
Dispose of any residues in accordance with State and Federal laws. Consult your owner’s manual or your local equipment 
dealer for cleanout procedures for your injection system.

SPRAY DRIFT 
AERIAL APPLICATIONS 
• Do not release spray at a height greater than 10 feet above the ground or vegetative canopy, unless a greater 
application height is necessary for pilot safety. 
• Applicators are required to use a medium or coarser droplet size (ASABE S572.1). 
• Applicators must use 1/2 swath displacement upwind at the downwind edge of the field. 
• 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 for fixed-wing aircraft and 75% or less for helicopters. Otherwise, the boom length 
must be 75% or less for fixed-wing aircraft and 90% or less for helicopters. 
• If the windspeed is 10 miles per hour or less, applicators must use a minimum of ½ swath displacement upwind at the 
downwind edge of the field. 
• When the windspeed is between 11-15 miles per hour, applicators must use a minimum of ¾ swath displacement upwind 
at the downwind edge of the field. 
• Do not apply during temperature inversions. 
GROUND BOOM APPLICATIONS 
• User must only apply with the release height recommended by the manufacturer, but no more than 4 feet above the 
ground or crop canopy. 
• Applicators are required to use a medium or coarser droplet size (ASABE S572.1). 
• Do not apply when wind speeds exceed 15 mph at the application site. 
• Do not apply during temperature inversions. 
AIRBLAST APPLICATIONS 
• Sprays must be directed into the canopy. 
• Do not apply when wind speeds exceed 15 mph at the application site. 
• User must turn off outward pointing nozzles at row ends and when spraying outer row. 
• 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 
• 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 manufacturer 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. 
8

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. 
AIR ASSISTED (AIR BLAST) FIELD CROP SPRAYERS 
Air assisted field crop sprayers carry droplets to the target via a downward directed air stream. Some may reduce the 
potential for drift, but if a sprayer is unsuitable for the application and/or set up improperly, high drift potential can re sult. It 
is the responsibility of the applicator to determine that a sprayer is suitable for the intended application, that it is configur ed 
properly, and that drift is not occurring. 
Note: Air assisted field sprayers can affect product performance by affecting spray coverage and canopy penetration. 
Consult the application equipment section of this label to determine if use of an air assisted sprayer is recommended.

*Colorado potato beetle - In situations where Colorado potato beetle populations are known or suspected to be difficult to control with current insect 
control products, the inclusion of piperonyl butoxide (PBO), a synergist, with STEWARD® EC insecticide may be necessary to achieve optimum control. 
In these situations, a combination of STEWARD® EC insecticide applied at a rate of 6.7 – 11.3 fl oz/A combined with a product containing 0.5 lb ai/A of 
the synergist piperonyl butoxide (PBO) may be necessary to achieve the most effective control of Colorado potato beetle larvae. 
Apply the low rates on small plants, small insects and light infestations of insects. Use intermediate rates on large insects and heavier infestations of 
insects. Use the highest specified rate for controlling severe infestations. Apply STEWARD® EC insecticide as a thorough coverage spray using 
properly calibrated air or ground spray equipment. Use sufficient water to obtain thorough and uniform coverage. For aerial application, use a 
minimum of 5 gal/A of water. 
**Potato tuberworm foliar feeding larvae – STEWARD® EC insecticide is most effective when applied by ground, air or overhead chemigation to 
vigorously growing plants through tuber bulking prior to the beginning of crop senescence. For control of potato tuberworm foliar feeding larvae, apply 
STEWARD® EC insecticide when tuberworm larvae and/or moth counts reach locally established treatment threshold populations. STEWARD® EC 
insecticide is absorbed into leaf tissue via translaminar movement and is most effective when applied to vigorously growing plants through tuber bulking 
(Growth Stage IV) prior to the beginning of crop senescence (Growth Stage V). Repeat applications of effective insecticides may be needed to keep 
tuberworm larvae populations as low as possible prior to harvest in order to reduce the risk of tuber damage. Failure to adequately control tuberworm 
larvae prior to crop senescence or vinekill increases the risk of tuber damage. To improve control of adults (moths), apply STEWARD® EC insecticide in 
a tank mix with a pyrethroid insecticide. 
Potato tuberworm is a difficult pest to control due to several factors; eggs can be laid deep in the canopy and on the underside of the leaf, and larvae feed 
inside the leaves prior to moving to the soil to feed on the tubers. An integrated spray approach is essential. Foliar sprays alone (ground or air) may not 
provide adequate control of larvae in the mid to lower crop canopy. For best results, apply via chemigation or integrate chemigation applications into the 
foliar spray program. Ensure thorough coverage by using sufficient spray volumes. For ground applications use at least 10 gal/A of water. For aerial 
applications, use at least 5 gal/A of water. For best results with foliar sprays, add Methylated Seed Oil (MSO) as a spray adjuvant at 1 gal per 100 gal of 
spray volume (1% v/v). For chemigation applications, apply in 0.1 to 0.2 inches of water per acre and add MSO at 12 to 16 fl oz/A. 
 Do not make more than two sequential applications of STEWARD® EC insecticide for control of potato tuberworm before rotating to another registered 
 insecticide having a different mode of action.
